The best air conditioning system selection guide

Employers and industry experts have always been concerned about selecting the best system given the range of air conditioning systems and equipment. When selecting an appropriate air conditioning system, a number of variables should be taken into account, including the weather, the intended use of the space, electricity consumption, the conditions and facilities needed to operate the system (such as the presence of an engine room, patio, or terrace), and the initial cost of purchasing the equipment. All of these situations are made possible following consultation with the facility engineers. In this post, we'll introduce several tools and equipment to assist you in selecting the best air conditioning system, therefore staying with us.

numerous varieties of air conditioning apparatus and systems

We are fortunate that our nation produces and supplies a variety of air conditioning systems and equipment, some of which are more beneficial than others.

Ducted Split
Compression chiller (air, blue) / mini chiller (air)
Air conditioner and split AC unit
air conditioner
Fan coil
Airwasher
Evaporative Cooler

We will go through each of these gadgets' unique traits in the sections that follow.

apparatus for ducted split

When it comes to cooling and heating a unit, split duct and split channel are actually the same thing. A range of 18,000 to 60,000 BTUs per hour are offered by these devices. While duct splits and splits operate in a similar manner, splits are only intended to chill one room or one space, whereas duct splits can simultaneously cool multiple rooms. Split ducts should typically be fitted with hot water coils that draw heat from the heating package of the same unit or the building's main engine room in order to warm the atmosphere during the colder months of the year. The high electricity usage and associated expenditures, as well as the requirement to build adequate ducting and electricity supply (three phases in units above 200 square metres), are some factors that should be taken into consideration when choosing a split duct. During business hours, you can speak with a Dematahheiz professional to discover the precise capacity and appropriate duct splits for your project.

Mini chiller or compression chiller

Although there are many different types and uses for chillers in industry and air conditioning, air conditioning systems are where they are most commonly used. Chillers come in a variety of capacities, and facility engineers or heating specialists determine the capacity that is needed.
Compression chillers' air conditioning operation is based on the cooling and pumping of circulating water to fan coils and other air conditioning components. In a way that the compressor chiller cools the water in the evaporator before transferring the cooled water via the pump to the air conditioner or fan coil within the building, which subsequently cools the surrounding air. In terms of performance, chillers typically come in two varieties: compression and absorption, with compression being the most practical. According to the kind of condenser, condenser chillers can be either air-cooled or water-cooled; the water-cooled variety has better efficiency and is more cost-effective initially while using a lot of water in the cooling tower. It is an air cooler. Furthermore, areas of Sharjah where the summertime relative humidity is greater than 50% are not suitable for water chillers. Due to the efficient reduction in water use and the absence of a water cooling tower, air chillers are more often used. The chillers can also be classified into different types of scroll, piston, centrifuge, and screw compressors depending on the type of compressor that is used in them. The number and type of compressors will be chosen based on the project's technical and financial requirements as well as the environmental and meteorological conditions. became. Mini chillers, also known as little air-conditioning chillers, are chillers that are smaller in size and only utilised for one unit. Allocating space for their installation on the building's terrace or roof is one of the factors that should be taken into account when selecting micro chillers. In this system, the ambient air is cooled by the fan coils or the air conditioner, which are positioned within the appropriate unit. The water is chilled in the micro chiller and then delivered by the pump to the fan coils or the air conditioner. In order to assess the capacity of the mini-chiller needed for your units, you may get in touch with the professionals at the air conditioning unit of the Demataghiz group. Mini chillers typically have a refrigeration capacity of 3 to roughly 15 tonnes and are made and supplied with a scroll compressor.

Split Ac Unit and Ducted Split

Because of their independence, relatively low initial purchase cost, ease of installation and operation, and suitable power in quickly cooling the air and reducing the humidity of the environment, gas and split air conditioners are ideal for hot and humid climates. These systems operate using the compression refrigeration cycle, refrigerant gas, and single-phase power. The disadvantage of air conditioners and split systems is their high energy consumption, which must be considered. In addition, because gas and split air conditioners reduce air humidity, they are not suggested for use in places with a moderate and dry environment. It should also be mentioned that gas and split air conditioners are most suited for small buildings and should not be used in large or luxurious projects. To assess the air conditioner and split capacity needed for your room or unit, call the heating experts during office hours.

Air Handling Unit (AHU)

Air conditioners come in flat, industrial and sanitary (hospital) varieties. These devices have the same components and functions as fan coils, with the exception that air conditioners use a fraction of fresh air for air circulation, whereas fan coils primarily use air from within the building. One of the most noticeable distinctions between the air conditioner and the fan coil is its use in big venues (conference halls, passenger terminals, flower houses, medical centres, cinema halls, etc.), ability to manage the humidity of the ambient air, and filtration. They have a more powerful and efficient entrance to the air system. If fan coils are employed independently in each area of the building, it should be remembered that air conditioners are typically used centrally in buildings and that the appropriate air produced in them is distributed to different sections of the building through a channel. put in place and used.

Fan coil unit device

Blower fans and heat exchangers (coils) typically make up fan coils, as their name suggests. These devices also include additional parts and apparatus, such as an air filter, a blower, an electric motor, and a distillation tray.
A fan coil is actually a form of heat exchanger that circulates hot water from the engine room boiler or gas package during the cold season and cold water produced by the chiller during the hot season inside its copper coil. The air in the desired environment is heated or cooled by pulling air into the fan coil, where it is filtered and then passed across the coil's hot or cold surface. The fan coils are manufactured and delivered in five different ceilings, floor, ceiling, wall, and channel models, as well as in all different types of surface and built-in, depending on the requirements of the project and the installation location. In terms of plumbing, they are additionally separated into 2-pipe and 4-pipe kinds. Two pipes are utilised for cold water and two pipes are used for hot water when there are four pipes. As a result, simultaneous cooling and heating will be possible in 4-tube fan coils. One of the factors to consider when selecting a fan coil is the appropriate type for the project, not taking up much space and not requiring ductwork, the ability to cool and heat at the same time (in the case of 4 pipes), and the ability to independently adjust the temperature in each room. by using a separate thermostat and limiting the transfer of pollution across departments, particularly in medical and hospital settings. The necessity for many pipes, the inability to adjust humidity, and the loudness of the ventilation fan, particularly in the bedroom, are some of the drawbacks of the fan coil. So that it can effectively cool and heat the surroundings while operating at the lowest fan speed and with the least amount of noise, it is always preferable to select a fan coil that is one size larger than what is needed for each space.

Air Washer Unit Device

An airwasher is a device that uses evaporative cooling to chill and raise the relative humidity of the surrounding air (much like a water cooler). It is best used in hot, dry climates with summertime relative humidity levels of less than 40%. This method has several benefits over condensation refrigeration cycle-based systems, including the ability to chill vast buildings while using less electricity and the ability to clean the ambient air.

The inability to regulate air humidity, the inability to divide the air into multiple compartments, the ongoing requirement for water, the potential for nozzle clogging, and the associated expenditures are some of this device's drawbacks.
In factories, workshops, large exhibitions, etc., air washers are frequently used. You can speak with the Demataghez collection professionals during business hours to ascertain the capacity and select the ideal airwasher for your salon.

Evaporative Cooler

Evaporative Coolers, which employ the evaporative cooling method to chill, raise the humidity, and condition the air in the appropriate environment, are one of the more traditional and well-known cooling devices. Evaporative Coolers are only appropriate for use in hot, dry places due to the rise in relative humidity; they are not advised in Sharjah regions with relative humidity exceeding 40% in summer (such as the northern or southern regions of Iran). We can list the low electricity consumption, affordable cost, and simplicity of installation and maintenance of Evaporative Coolers as some of their advantages. Evaporative Coolers come in front, portable, high-pressure, and even industrial models (large capacity for salons).
Different types of plastic or cellulose pads are now used in Evaporative Coolers; cellulose pads are, of course, better and more effective than traditional pads for a number of reasons.
