Chiller Cooling

What is Chiller? How Does the Chiller System Work?

Chiller, which is called chiller in English and translated into Turkish as cooling systems; These are systems called injection cooling systems that transfer heat from one source to another. Chiller cooling systems consisting of compressor, condenser, expansion valve and evaporator work by cooling the compressed and heated gas in the compressor in the condenser. Then, due to the pressure of the gas passing through the expansion valve, its temperature decreases and it liquefies. While passing through the evaporator, it takes the heat from the liquid to be cooled, comes to the compressor as a gas at low pressure, and is compressed again. The working system continues in this way. chiller system;
  • Water cooled chiller
  • It is divided into 2 as air cooled chillers.
Apart from this, heat pump chiller, 4-pipe chiller, free cooling chiller systems are also used. In order to answer the question of how the chiller system works, it is necessary to examine the chillers separately.

Air Cooled Chiller

Chiller cooling systems are grouped according to their different characteristics. The biggest distinction is what the heat source is. If the heat is thrown into the air, it is called an air source chiller, if it is thrown into the water, it is called a water source chiller. Air-cooled chiller systems operate in the form of the energy of the refrigerant gas in the chiller, gained through the evaporator and compressor, on air-cooled coils. Compressed in the compressor and high temperature gaseous refrigerant is sent to the condenser. With the help of fans, heat transfer takes place by providing air flow on the battery surface. Cooling is completed by transferring the heat from the gas to the air.

Water Cooled Chiller

Water-cooled chiller cooling systems, unlike the air-cooled chiller operation logic, cool the hot gas in the condenser circuit with water. Shell & Tube or plate type heat exchangers are used. For those who say how the chiller works, it should be noted that there is a need for a water source during the supply of the cooling water to be circulated in the condenser in water-cooled chiller systems. Water resources; It can be stream, sea, cooling tower or standard waterline. In water-cooled chiller systems, it is generally used in places where the space where the system will be placed is limited, where energy costs are important but water costs are low. Since water-cooled chiller models have the ability to work indoors, they also provide an ideal solution when it is desired to be positioned closest to the desired cooling area. Water-cooled chiller systems can also be used for air-conditioning of marine vehicles. Finally, for those who say how the chiller works, it should be noted that water-cooled chiller systems provide 65% smaller volume compared to the chiller device of similar capacity, as it minimizes the device volume. At the same time, due to the increase in compressor operating performance, it consumes less electricity and provides high performance. Chiller chillers; It is used mainly in industrial production facilities, food and pharmaceutical industry, plastic production facilities, cosmetics manufacturing facilities, cold storages, hotels and hospitals. However, the chiller project suitable for each usage area should be specially prepared.
