Ducted AC Unit

Ducted AC units are independent home or office air conditioning and heating systems. In the rest of this article, we will answer all your questions about technical specifications, capacities, and prices of all types of ducted AC units for wholesale purchase.

Ducted AC Review, Selection, and Pricing

What is Ducted AC? Ducted air conditioners, commonly known by the international name Ducted Split Air Conditioner Unit, are used by many experts for ducted ACs and are considered one of the most common heating and cooling (Ventilation and Air Conditioning) systems in apartments today.

By providing cool and fresh air in the summer and hot air in the winter (by transferring cold or hot air through ducts installed in the dropped ceiling), ducted ACs or ductless split ACs bring the temperature of all rooms in a residential unit to a comfortable temperature conditions and provide the desired air conditioning.

Ducted AC consists of two parts or components, the Evaporator Coil (Internal Unit) and the condenser (External Unit), which are connected through 2 pipes or tubes made of copper or aluminum.

One pipe carries refrigerant from the compressor to the evaporator to create a cooling effect, and the other pipe carries it back for compression and recirculation. During the cooling cycle process, the air in the internal unit is cooled and distributed through the channels inside the dropped ceiling.

How Ducted Split AC Systems Works (Heating + Cooling)

The way that a ducted split AC works is similar to a ductless split AC. Directing the refrigerant gas to the condenser after condensing in the compressor (with high temperature and pressure). Then, the refrigerant gas circulates in the condenser and blows the fan. Therefore, the heat is transferred to the outside, and the refrigerant turns into a liquid phase at the outlet of the condenser.

After passing through the expansion valve, the refrigerant liquid encounters a sharp drop in pressure and temperature and enters the coil. By absorbing the heat, it cools a large amount of air. The cold air is then directed through channels to the entire place.
However, Ducted ACs' heating performance is different from that of air conditioners and air handling units, and it is done using different methods, which will be described below.

Methods of Heat Supplying in Ducted AC Systems and Side Considerations

There are three ways to set the ducted AC to work for winter heating, using a hot water coil, an electric coil, and a heat pump, each of them described below:

• The Hot water coil: In buildings with Ducted AC or channels, the most common method of providing heating, used in 90% of cases, is to use a hot water coil that fits the dimensions of the outlet opening of each ducted AC. It is recommended to use a hot water coil to provide heating in inverter Ducted ACs, which can provide cooling and heating through the unit's compressor because, with this method, we can significantly reduce electricity consumption and related costs in the winter season. In winter, hot water is provided by the building's central heating system (engine room) or by the heating package of each unit, and by entering the hot water coil, it provides the hot air required by each unit. Also, remember that if you do not use the automatic Air Vent on the hot water coil, you must ventilate the hot water coil every year at the beginning of the cold season!
  
  
• The Heat pump: Another method of providing heat is to use Ducted AC units equipped with a heat pump system. In addition to high electricity consumption and insufficient heating capacity in many areas, heat pumps can cause the condenser to freeze in sub-zero winters.
  
  
• The Electric coil: Using electric coils in Ducted Split ACs to provide heating is rare and generates high electricity consumption. In this case, there is no need for hot water in the package and the machine room for the heating system, so this model is used in places that do not have gas mains or a central machine room.
  
  

Types of Ducted AC

Ducted split AC systems refer to an HVAC (heating, ventilation, and air conditioning) system that uses ductwork to distribute conditioned air throughout a building. Each type of ducted split AC system has advantages and disadvantages and is selected based on several factors. They are commonly used to maintain comfortable indoor temperatures in homes, offices, and commercial buildings. Here are some types of ducted split AC systems:

Power consumption

Grade A Ducted Split AC Units: This type of ducted AC is designed just to reduce the cost of electricity consumption with the energy classification of Grade A. In the inverter unit, a compressor with variable speed capability is used, which reduces the compressor speed as the temperature of the internal environment decreases and increases as the temperature increases.

Grade A Ducted Split AC Units: This type of split air conditioner does not have an inverter and a fixed speed (ON/OFF) and has a higher power consumption than the inverter split air conditioners of grade A; for this reason, they have an energy class B label.

Electricity Type

Single-phase (220) volt ducted AC: Produced with capacities of 18,000, 24,000, 30,000, and 36,000 use single-phase electricity.

Ducted AC with three-phase electricity: ducted split ACs with capacities of 42,000, 48,000, and 60,000 use three-phase electricity.

Compressor type

Rotary compressor: The main components of this type of compressor are a fixed cylinder, piston (rotor), and blade. Compared to piston compressors, rotary compressors have less noise, vibration, power consumption and dimensions, more balanced operation, and higher efficiency.

Scroll compressors: Scroll compressors are more efficient and have a higher capacity than the other two types of compressors. This is why this type of compressor is usually used in ducted ACs with a capacity of more than 36,000.

Piston compressor: This is the oldest type of compressor. Most ducted ACs equipped with this type of compressor can be used in hot and tropical areas, such as cities in the south of the country.

Brand

Iranian: In recent years, many manufacturers in Iran have started to produce and supply high-quality Iranian ducted ACs using international standards. Some popular Iranian ducted AC brands include DamaTajhiz, G Plus, Iran Radiator, and Goldiran.

Non-Iranian: Some popular imported ducted split ACs available in the Iranian market include Hisense, Midea, Tech Electric, LG, and Green, which are offered in various capacities.

Ducted ACs Internal Components

The two internal units (evaporator or air generator) and the external unit (condenser) of the ducted ACs have different components, each with a specific function.

The main parts of a ducted AC's evaporator

Ducted AC evaporators consist of five parts:

1. The Body of the Evaporator: the body is usually made of thick and high-quality galvanized sheet metal with high resistance to corrosion and rust.
2. The Evaporator Coil: which contains the refrigerant.
3. The Fan and Electromotor: The fan and electromotor rotate and start to transfer the temperature created by the refrigerant to the air outlet valves.
4. The Drip Pan or Tray: This prevents water droplets on the coil from dripping to the ceiling.
5. The Air Filter: The air filter is located in the air outlet, improving the quality of the air entering the rooms.
   
   

The figure below shows different views of the internal parts of the condenser/evaporator:

The Main Components of the Ducted AC Condenser

The condenser of the ducted AC consists of seven parts, which are as follows:

1. The Compressor: The compressor is the main part of the condenser and is filled with refrigerant gas R410a or R22, depending on the type of compressor.
2. The Electric Motor: Or condenser fan motor is connected to the compressor, converts electrical energy into mechanical energy, and causes the condenser fan to rotate.
3. The Condenser’s Fan: A condenser fan that moves air across the condenser.
4. The Expansion Valve: Expansion valve that expands the refrigerant flow.
5. The Four-Way Valve: The four-way valve is responsible for reversing the cooling and heating mode of the ducted AC.
6. The Accumulator: An accumulator or liquid breaker is a temporary tank for refrigerant that prevents liquid from entering the compressor and adjusts the amount of oil returned to the compressor.
7. The Drier Filter: The drier filter is a piece that removes any moisture, dust particles, and deposits from the refrigerant circulation cycle.
   
   

In the figure below, you can see the internal view of the ducted AC condenser and its constituent parts:

Where Are Ducted ACs Used For?

Ducted ACs or split channels are used for cooling/heating in houses and offices as a luxury option with a cost of electricity consumption equal to and sometimes more than a ductless split AC (according to cooling load and thermal calculations). Generally, ducted ACs are used when the ductless split or other air conditioners are insufficient.

Using a ducted split AC, you can have an independent cooling and heating provider for a separate building unit. As a result, the maintenance and operation costs of a central refrigeration system such as a chiller are reduced.

The experts of the specialized heating equipment of DamaTajhiz can help and advise every builder and mass builder to choose the most suitable Ductless Split AC Unit based on each project's technical and economic conditions.

Ducted AC Capacity Determination Guide

During the initial estimation of the cooling capacity of the ducted split AC or the split channel required for each unit in climatic conditions (Tehran, Mashhad, Karaj, Isfahan, Erbil, Kabul, Sulaymaniyah, Halba, and other cities with similar climates) in summer and the middle floors of the building. Which are not exposed to direct sunlight on the roof through summer and the coldness of the roof surface in winter.

For every 35 or 40 square meters of the total area of the apartment, about one ton of refrigeration is considered (400 BTU/hour per square meter).

If each unit's area is more than 120 square meters, it is better to use two devices for each unit. Also, remember that each BTU/hour of 12000 is equivalent to one ton of refrigeration.

1. For apartments up to 150 square meters, single-phase ducted ACs with inverters can be used. Still, with 32 amp electricity, there is no need to demand three-phase electricity from the electricity provider services.
2. For apartments up to 200 square meters, you can use single-phase ducted split ACs with inverters by using single-phase electricity but 50 amps.
3. Our experts say builders must obtain three-phase electricity for units above 200 square meters.
4. When choosing ducted ACs, one of the points of interest is to consider their aeration volume, usually equal to 400 CFM for each ton of capacity, directly impacting the device's noise production.
5. For more information, refer to the approximate calculation table below to determine the required capacity according to the conditions and bases of the mentioned calculations.
   
   

The following capacity estimation table is approximate and only for residential apartments with weather conditions such as Tehran, Rasht, Babol, Sari, Karaj, Mashhad, Isfahan, Kermanshah, Shiraz, Beirut, Sulaymaniyah, Erbil, Mosul, Aleppo, Hama, Mazar-i-Sharif, Kabul, Latakia, Kirkuk, etc. And with a distance of 2.8 meters from the ceiling to the floor (except for situations where people are gathering and increasing latent heat, the use of high-consuming electrical equipment, and glass walls).

Ducted Split AC Unit Side Considerations

Before ordering, pay attention to the device specifications and information, whether single-phase or three-phase electricity consumption. Also, compare the electricity consumption ampere of the device with the ampere of your building's electricity meter.

Suppose you need a ducted AC for hot and dry weather type cities such as Zahedan, Zabul, Yazd, Kerman, Baghdad, Najaf, Karbala, Riyadh, Madinah, etc., Or hot and humid weather type cities such as Ahvaz, Abadan, Bandar Abbas, Kish, Chabahar, Doha, Bushehr, Bandar Mahshahr, Basra, Karachi, Sharjah, Dubai, Abu Dhabi, Muscat, Sana'a, Jeddah, etc. Ask for opinions and calculations of HVAC facility engineers and experts about tropical compressors, condensers, and gold or bluefin evaporators.

Note: You also need to consider an extra 20% to 30% of the cooling capacity of the device for the mentioned weather types.

Ducted AC Unit Features

These features include:

• The ability to install horizontally in the minimum space above the false ceiling in each unit
• Simple and cheap maintenance and repair of split duct compared to central air conditioning system (chiller)
• Removal of extensive piping on the floor and ceiling of the units
• Removing vertical ducting and preventing the reduction of common space in apartment complexes
• Uniform transfer of cold and heat through the channels implemented inside the false ceiling of each unit
• Independence for each apartment unit and as a result reducing maintenance costs and not needing to use a maintenance technician
  
  

Ducted AC Unit Advantages & Disadvantages

The ducted AC system has advantages and disadvantages that you need to know before buying this device in order to have a better shopping experience:

Ducted AC Unit Advantages

The advantages of buying and using ducted AC are as follows:

• Dual use for providing cooling and heating
• Eliminating the need for a chiller, cooling tower, central boiler, radiators, and related piping
• The possibility of using fresh air if needed and installing an air suction channel
• Removing humidity or hot summer air, air filtration, and reducing air pollution
• The possibility of using a heating system with a spa coil and an independent heating package
• The possibility of installing ductwork for large spaces with various uses
• The possibility to install an air filter and control the temperature of any part of the space by employing a thermostat and thermostatic valves to adjust the air separately
• Easy setup and use 
• Suitable lifespan
  
  

Ducted AC Unit Disadvantages & Limitations

In addition to their many advantages, ducted AC devices also have a number of limitations, of course, there are different methods to solve each of these limitations and use them more efficiently. In the following, we will describe the disadvantages of ducted AC and how to solve them.

Independent Temperature Control Incapability

In the ducted AC unit, it is not possible to control the temperature of each room or unit independently. This means that in a building, all the rooms connected to a ducted AC will have the same temperature and will be cooled or heated at the same time.

Solution:

• This limitation of the ducted AC can be controlled to some extent by the correct design and dimensions of the channel branches and considering their distance to the internal unit of the device.
• But to completely solve this problem and control the amount of air entering each room, instead of using fixed valves, it is necessary to use motorized or thermostatic valves (so-called mechanical or electric dampers).
• Then each valve should be controlled by a thermostat installed in each room to adjust the opening and closing of the valve with the thermostat command. As a result, it is possible to control and adjust the volume of hot or cold air entering each room/unit.
  
  

Note: With the installation of these dampers, the total price of the ducted AC system will also increase; For this reason, in such a situation, it is suggested to use other alternative systems such as a fan coil and chiller in the project in question.

Extreme Sound Level

The sound level of the ducted AC system is one of the things that may be annoying for some residents of the building. This sound is created due to the passage of air inside the channels built into the false ceiling of the building and the operation of the ventilation fan of the indoor unit, especially when the air is sucked into the device, and by the ducted AC, this sound is transmitted to the space inside each unit. This problem is solved by different methods that are mentioned below.

Solution:

• Installing a suction valve or a few meters of insulated flexible duct for air return in the air suction path into the ducted AC. Buying ducted AC whose internal components of the evaporator, such as the blower fan and electric motor, are BLCD type or variable speed and low noise.
• Paying attention to the important points related to the pressure drop, speed, and wind of the airflow of the device when designing the ducted AC channeling and using a ductulator when calculating and designing the distribution channels and air valves of the ducted AC and as a result of implementing channels with the appropriate cross-section
• Installing the device's internal unit in a space away from the bedroom and living room; For example, above the false ceiling of the corridors and entrances of each unit are suitable places to install the ducted AC panel.
• Choosing a device with an aeration volume appropriate to the project's needs; Also, if you need to use a device with a high-capacity tonnage, you can use two ducted ACs with a lower tonnage, which usually allocates one device to the hall and reception and the other ducted AC to the bedrooms.
  
  

High Electricity Consumption

The ducted AC heating and cooling system is such that it ventilates all the internal spaces of each unit at the same time and equally. As a result, if a person, for example, only needs to ventilate the living room, all the rooms and spaces connected to this system are also ventilated. Therefore, the waste of energy and electricity consumption of ducted AC increases compared to split air conditioners.

Solution:

• Using inverter ducted AC and low consumption. Paying attention to the distance between the internal and external ducted AC unit installation location
• Using two ducted ACs to separately control the ventilated spaces of each unit, one in the hall and reception and the other in the corridor of the bedrooms.
• It is also generally recommended that you use any ducted AC in a space where more people are usually present at the same time during most of the day.
  
  

Tropical Ducted Split AC Units Benefits and Advantages

Tropical ducted split AC units have many unique features compared to a normal ducted AC, which is as follows:

• The most obvious characteristic of the tropical ducted AC is its compressor. The tropical ducted AC compressor works in such a way that it performs well despite the high temperature of the outside. Generally, scroll compressors are used in this type of ducted split unit.
  
  
• Evaporator and condenser coils in tropical ducted ACs are usually either Blue Fin or Gold Fin. Because in very hot and humid regions, there is always some acidic salt in the air and the rainwater. Moisture and salts can accumulate on the coil's surface, negatively affecting the device's efficiency. Evaporator and condenser coils being equipped with Blue Fin or Gold Fin epoxy coating prevents the accumulation of acidic salt and moisture on the coils.
  
  

Although tropical ducted AC units are designed and manufactured for temperatures of 21 to 57 degrees Celsius, they can also be used in regions with other weather types and temperatures.

Buying Ducted AC Units

The first step to choosing a ducted AC unit should be to pay attention to the dimensions and surface area of the building, the installation location, and the capacity of the device. Because ducted ACs are produced and supplied in different types with different cooling, heating, and ventilation capacities, before choosing and buying the required ducted AC, you should consider the size and use of your environment so that you can make the right choice. And be correct in the model and capacity of the ducted air conditioner. Then, things like single-phase or 3-phase electricity, energy consumption, features, brand, and price of ducted AC should be examined.

Another point that should be considered when buying a ducted AC is the material of the ducted AC ventilation fan.

In general, we have the following three options in terms of selecting the ventilation fan in ducted AC units:

• The galvanized ventilation fan, which produces more noise compared to the next options but is more stable and also provides a better static pressure for the passage of air inside the channels.
• The fan is made of compressed plastic, which has a lower price and less noise, but it is not recommended for cold areas at all.
• The fan is made of polyamide with compressed carbon fibers, which is the best ventilation fan in duct ACs and is completely resistant to a temperature of 120 degrees Celsius. And in addition to fully providing the airflow and pressure passing through the channels, it will have less noise than galvanized fans. Which, of course, has a higher price.

Factors to Observe When Installing a Ducted AC

Here are the ten important factors you best consider when installing a ducted AC system in your home or office:

1. The correct choice of capacity, dimensions, type, and installation location of the ducted AC unit.
2. Deciding whether to use a normal type ducted AC unit or an inverter type (basically, inverters enable less electricity consumption and prevent electric shocks by starting and changing the idle speed of the compressor) and it is better to use one for the capacities of 24,000 and above.
3. Correct and conscientious implementation of the device and copper pipes/tubes to benefit from the highest efficiency of the ducted split AC system.
4. To determine the right capacity, first, send the latest architectural plan of the units and floors of your building via fax or email to the DamaTajhiz experts as a consulting and sales center for all types of cooling and heating devices.
5. Before ordering, examine the type of electricity of your building to find out if it is a single-phase or three-phase. As well as the amperage of the electricity consumed.
6. The importance of the ventilation fan balance in the performance of the device directly affects the lifespan of the ball bearing of the motor to maintain the dynamic balance of the fan. Also, pay utmost attention to the device being completely horizontal, aligned, and balanced.
7. Considering that the recycled air of the same unit is usually being used and circulated, it is necessary to install the device on top of the dropped ceiling or any other space where the device is located. Two areas need to be separated using a porcelain blade or tile installation so the air of the same unit will be recycled.
8. At the time of ducting, the place of installation of air output valves of the device should have the greatest distance from the air input valves.
9. Due to the importance of determining the temperature of the inside air and the turn-off and turn-on commands of the thermostat to control the operation of the ventilation fan, in some brands that do not have a thermostat in the air suction canal, determining the location of the thermostat installation is very important. Therefore, when determining the installation location of the thermostat, observe the height 140 cm from the floor and in a place without direct sunlight or airflow.
10. To run copper pipes at height, use an oil trap for every 6 meters of copper pipe.
    
    

Note: The cost of implementing air distribution, recycling channels, and copper pipes between the inner duct and the outer panel varies based on the distance and length of the path between these two parts. However, due to the manufacturer's Residential unit's request about the average installation price, as a general estimate, the cost of implementing them can be about 20% to 30% of the initial price of the ducted AC unit (this estimate is approximate).

Ducted AC Internal Unit (Evaporator Coil) Installation Mistakes

In many projects, the internal unit of the device is installed before the installation of the dropped ceiling. When installing a dropped ceiling, the possibility of repair and the need to access the internal unit must be considered.

Otherwise, some part of the dropped ceiling will be destroyed for the partial maintenance of the evaporator and will cause a significant extra cost; therefore, it is necessary to consider a space for access to the internal unit while installing the dropped ceiling.

Ducted AC & Mini Chiller Comparison

Due to the builders of residential units' rapid requests about comparing the cost of preparation, implementation, and operation of ducted split units to the mini chillers (fan coils) for one unit. According to the calculation and estimation of DamaTajhiz sales experts, the correct estimation of the price comparison depends on several factors such as the capacity, selected brand, technical characteristics and specifications of each piece of equipment, the size of the unit's infrastructure, the location and how it is implemented, etc.

But in normal conditions, the total cost of buying, installing, and running a ducted AC system is about 40% lower than the cost of buying, installing, and running a mini chiller (for a single unit with a similar capacity and brand).

In operating costs, which mainly include the cost of electricity consumption + the cost of periodic repairs and refrigerant gas charging, there is not much difference between a ducted AC unit and a mini chiller. But if ducted ACs with a capacity of more than 3 tons of refrigeration, if the suction valve under the device is not installed and the air channel is not properly designed, the noise of the air passage will attract attention.

Iranian Ducted Split ACs Overview

In the past decade, Iranian-made ducted ACs have been through major changes in combining science and industry, making them comparable to the popular and elder brands of ducted split ACs worldwide. This feedback is evident in the air conditioning and heating industry and Iranian brands' warranty and after-sales service.

It is one of the important factors in attracting customers and increases the peace of mind for buyers when choosing these home essential products. It should be mentioned that this evolution in production started in the last decades, starting with making small equipment such as pumps, boilers, burners, fan coils, and chillers and coolers, and now, after several decades, it is time for Iranian brands such as Iran Radiator, DamaTajhiz, Sarayel, etc. to produce high-quality and long-lasting ductless splits and ducted splits.

Important Points to Consider When Using a Ducted Split AC Unit

If a person is close to the device, the noise of the fan and the passage of the suction air of the device in some brands may be heard loudly, so it is better not to install the ducted split unit inside the dropped ceiling of the bedrooms, TV room or the living room. The appropriate place to install it is as much as possible above the dropped ceiling of the entrance, hallways, or the communication spaces inside the residential units.

Note: To prevent annoying noise in the bedrooms, it is better that the capacity of the installed ducted AC above the dropped ceiling of the bedrooms not exceed 2 tons of refrigeration.

Do not install the ducted AC unit above the dropped ceiling of the bathroom or kitchen. Suppose there is no installation of thermostatic valves to adjust the incoming air to each room (which is usually ignored). In that case, you will not have control over the temperature settings of each room separately.

One of the limitations of using a ducted AC unit is the installation of a condenser in the outer space of the building. Because installing many condensing units for an apartment complex (if not on the roof) can damage the appearance of the façade, if it is possible to install them on the roof of the building, in addition to checking the ability to suction the refrigerant gas from the internal panel to the condensing unit installed on the roof, the costs of implementing copper connection pipes and other components should also be considered.

The maximum length of the connecting pipes (copper or aluminum) between the internal panel and the outer unit is between 10 and 30 meters (based on the expert's opinion).

What is the Difference Between an Inverter and a Normal Ducted AC?

In normal or fixed-speed ducted ACs, the compressor's speed cannot be adjusted. This means that when the ambient temperature reaches the desired temperature, the compressor is turned off and turned on again when the ambient temperature changes. For this reason, they are called ON/OFF ducted ACs.

However, the inverter kit is a part that allows the user to control the temperature of the environment and change the speed of the compressor according to the desired temperature.

In other words, the ducted AC inverter can reduce the speed of its compressor motor when the ambient temperature reaches the user's desired temperature and, at the same time, maintain this temperature. This saves and reduces electricity consumption and keeps the compressor on during its operation.

This continuous activation of the compressor also makes the ambient air remain in a favorable state without a temperature drop. It should be noted that the sound level and power consumption of inverter ducted split units are lower, and their price is higher than normal ducted ACs.

The sound level of the Ducted AC Unit

To know the exact sound level of each ducted AC unit, you should refer to the catalog of its manufacturer or the technical specifications provided on the reference and specialized website of DamaTajhiz.

In general, a ducted AC internal unit is installed inside the dropped ceiling and uses a large fan to deliver air to all rooms. On the other hand, this air enters the space by passing through different channels. For this reason, the sound of the ducted AC evaporator fan can be heard completely in the interior of each unit. Therefore, it is recommended that the evaporator be installed above the dropped ceiling of the corridors and the entrance of each unit. It should be noted that the sound level of inverter ducted ACs is usually lower than the sound of fixed round or non-inverter models.

Of course, it goes without saying that to reduce the noise of the ducted air suction fan from the vent or grill under the device, you can also use the air return ducting.

Ducted AC Unit Maintenance and Service

One of the important points about the maintenance of the ducted AC is choosing the appropriate capacity of the device with the size of the desired environment and then its accurate channeling according to the space of the building. In addition, it is better to avoid turning off the ducted AC frequently during the day and night.

To increase the useful life of the ducted AC, be sure to pay attention to the periodic services of the device, some of which include the following:

• Check and wash the spa coil
• Washing the blower in the condenser fan
• Washing evaporator and condenser fins
• Checking and checking the power consumption of the device
• Refrigerant gas check and gas charging if needed
• Checking the ducted AC ceiling chassis
• Check (and repair if necessary) where the wires are connected to the terminal
  
  

Note: Keep in mind that periodic repair or service of ducted split AC is a specialized process and must be done by service members or authorized services of the product manufacturing company.

How Much is the Cost and Electricity Consumption of the Ducted AC?

In general, the electricity consumption of the ducted AC unit depends on various factors, including the capacity, whether or not the ducted AC has an inverter and the amount you consume from the device. In addition, the ducted AC consumes more electricity compared to the air conditioner and the wall split. Still, if you use a low-consumption ducted split AC or an inverter, you will save a lot of electricity. Note that predicting the monthly electricity cost of the Ducted AC is not an easy task. Still, if you use a Ducted AC without a high-capacity inverter around the clock, you should expect a high-cost electricity bill!

Of course, suppose the size of the unit you are looking for is more than 130 square meters. In that case, it is better to use two smaller ducted AC devices, one for the hall and reception (working during the day) and one for the rooms (mainly working at night), so that the cost of electricity and the sound they produce be divided and adjusted.
