Chiller AC Units


A chiller AC unit, also known as a chiller, is a type of air conditioning system that is commonly used in large commercial, industrial, and institutional buildings to provide cooling. It works by removing heat from the indoor air and transferring it to an external environment.

The chiller AC unit consists of several key components


The compressor is the main component of the chiller unit. It compresses refrigerant gas, raising its temperature and pressure.


The evaporator is where the chilled water or refrigerant absorbs heat from the building’s air or process equipment. As the refrigerant evaporates, it cools the air or water passing through the evaporator coils.


The condenser is responsible for rejecting the heat absorbed from the building or process equipment. It cools the hot refrigerant by transferring the heat to a separate cooling medium, such as water or air.

Expansion Valve

The expansion valve controls the flow of refrigerant into the evaporator. It reduces the pressure and temperature of the refrigerant, allowing it to absorb heat from the building or process equipment.

Chiller AC units can use different types of refrigerants, such as R-410A, R-134a, or R-22, depending on the specific model and environmental regulations. They are typically designed to provide a centralized cooling solution for large spaces, and the chilled water or refrigerant is distributed to various areas within the building through a network of pipes or ducts.

Chillers are known for their energy efficiency, cooling capacity, and ability to handle heavy cooling loads, making them suitable for applications like office buildings, hotels, hospitals, data centers, and industrial facilities.
