An air-cooled chiller is a type of chiller that uses air as the cooling medium to remove heat from a process fluid or coolant. It is commonly used in industrial and commercial applications where water is scarce or expensive, or where the cooling load is relatively small.
The basic components of an air-cooled chiller include:
Compressor: This is the heart of the chiller and is responsible for compressing the refrigerant gas and moving it through the system.
Condenser: The hot refrigerant gas from the compressor is condensed into a liquid by passing through a series of fins that are cooled by ambient air.
Expansion Valve: The liquid refrigerant is then passed through an expansion valve, which reduces its pressure and temperature.
Evaporator: The low-pressure, low-temperature liquid refrigerant then flows through the evaporator, where it absorbs heat from the process fluid or coolant, causing it to evaporate and return to the compressor as a gas.
The main advantage of air-cooled chillers is that they do not require a separate cooling tower or water source, making them easier to install and maintain. However, they are typically less efficient than water-cooled chillers and may not be suitable for applications with large cooling loads or in areas with high ambient temperatures.
Air-cooled chillers are commonly used in applications such as data centers, commercial buildings, and process cooling. They are available in a wide range of sizes and capacities to suit different applications.
