Guide to buying the best ducted split

Ducted split or channeled split is a good example of the new generation of air conditioning equipment, which, in addition to balancing and creating a favorable temperature in the environment, due to its modernity and occupying less space, also has a significant impact on the beauty and arrangement of each unit. The split duct device is similar to the split device in terms of performance, with the difference that this device is placed on top of the false ceiling and only a few air vents are visible in the environment. Currently, among the devices that are used for air conditioning, the split duct is particularly popular, because of the uniform transfer of cold and heat, removal of ambient humidity, the ability to install air vents on the wall and ceiling of the environment, etc. They are among the benefits that make people buy this device. In this article titled as a guide to buying the best split duct, how to calculate the capacity, differences between normal and inverter (low consumption) models, popular brands, use and benefits of this equipment, please stay with us to get the important points. Learn more about split ducts.

Application of ducted split

A ducted split is used for cooling and heating in residential apartments, offices, villas, etc. This equipment is considered a luxury option, with the cost of electricity consumption equivalent to or even higher than gas coolers (according to cooling and heating load calculations), and it is generally used instead of several splits in one unit. By using duct splits, in addition to providing cooling and heating for each apartment unit independently, the maintenance and operation costs of a central refrigeration system such as a chiller are also greatly reduced.

Ducted splits or channel splits in the capacity of 18,000, 24,000, 30,000, 36,000, 42,000, 48,000, and 60,000 BTU are produced and supplied in the form of single-phase or 3-phase electricity in different dimensions.

The difference between ordinary ducted split and inverter

Ducted splits are produced in two models, normal and inverter, in terms of performance and energy consumption. Common ducted splits only have two modes of off or on (with maximum power) in the operation of the motor or compressor, that is, there is no intermediate mode and compressor operation speed adjustment for them. However, according to the ambient temperature, inverters reduce or increase the speed of the compressor after a few minutes and can change the performance of the compressor in the range of 0 to 100, for example, 30%, 50%, etc. which means reduced energy consumption and longer life of the device.

Approximate calculation of ducted split capacity

By considering parameters such as square footage, area of the environment, and humidity percentage of the geographical location, we can choose the ducted split with the appropriate capacity. for example; If the air coefficient of Tehran is 400 and the size of the residential area in question is 100 square meters, by multiplying these numbers, we get the suitable split duct capacity 40000=400*100

Important point: before choosing and buying the required split duct, in addition to paying attention to the capacity and sufficient ventilation volume of the chosen split duct for the size of the desired space, other important issues such as the type of single-phase or three-phase electricity required by the device should be considered. Pay enough attention to the power supply in the unit as well as the physical dimensions, especially the height of the inner panel of the split duct for the possibility of placing it on top of the false ceiling of the respective unit.

Important points in choosing a ducted split

Among the points that should be considered in order to choose a better ducted split are as follows.

• Basically, inverter ducted splits provide the possibility of less electricity consumption and prevent electric shock by starting and changing the idle speed of the compressor, and it is better to choose the type with inverter for capacities of 24,000 and above.
• In order to determine the required ducted split capacity, first send the latest architectural plan of the units and floors of your building via fax or email to the heating equipment experts as a consulting and sales center for all types of cooling and heating devices.
• Before choosing and ordering the purchase of any of the ducted splits, in addition to the dimensions of the air conditioner or the internal panel, the issue of single-phase or three-phase electricity, as well as the ampere (A) of electricity consumed, taking into account the power and specifications Pay attention to the electricity meter of your unit.
• In general, the cost of implementing air distribution and return channels inside the units and implementing copper pipes between the inner duct and the outer panel of duct splits or channel splits is different based on the distance and length of the path between these two parts, but according to frequent questions Builders of residential units, as a general estimate, the cost of their implementation can be considered to be about 20% to 30% of the initial price of duct split (of course, this estimate is approximate).

Important point: before choosing and buying the required ducted split, in addition to paying attention to the capacity and sufficient ventilation volume of the chosen split duct for the size of the desired space, other important issues such as the type of single-phase or three-phase electricity required by the device should be considered. Pay enough attention to the power supply in the unit as well as the physical dimensions, especially the height of the inner panel of the split duct for the possibility of placing it on top of the false ceiling of the respective unit.

Also, if the surface area of your unit is more than 120 meters, it is better than two ducted splits, one for cooling and heating in the hall and reception (which will naturally be turned off during sleep) and one for the rooms (which is only when you light sleep) use. For this, in addition to the effective reduction of electricity consumption due to the division or zoning of the used spaces, we will have the possibility of less ducting, better air distribution, capacity selection and less noise by each of the split ducts.

Important points when installing split duct

Correct and principled implementation of ducted split and copper pipe in order to benefit from the highest efficiency of the split duct system.
Due to the importance of ventilation fan balance in the performance of the split duct and its direct relationship with the lifespan of the engine bearing, in order to maintain the dynamic balance of the ventilation fan of the device, pay utmost attention to the completely horizontal and leveled installation of the ducted split types in your installation location. .
Due to the importance of determining the temperature of the inside air and the commands of disconnecting and connecting the thermostat to control the operation of the ducted split ventilation fan, in brands that do not have a thermostat in the air suction path, determining the location of the thermostat installation is of particular importance. Therefore, when determining the installation location of the thermostat, observing the height of 140 cm from the floor, also install the thermostat in a place where there is no possibility of direct sunlight or exhaust air flow from the outlet air valve of the split duct.
If you have abandoned the implementation of air return channels, for the possibility of air circulation in the rooms (when the door of each room is closed), the entrance door of each room must have an air outlet valve to the hall and reception area, or under the door of each room. The room should have a distance of at least 5 cm from the floor of the room for air circulation.
At the time of ducting, the installation location of air return valves, ducted splits or channel splits should have the greatest distance from the air outlet valves.
Considering that the return air of the same unit is usually used in ducted splits, it is necessary to install the ducted split on top of the false ceiling or any other space where the device is located, that installation space with a porcelain blade or tile installation. Other public spaces of the building (above the false ceiling) such as corridors or corridors of the floors should be completely separated and the ducted split should be installed in a place and position where only the return air of the same unit or the desired space flows.
To run copper pipes at height, use an oil trap for every 6 meters of copper pipe length.
