Screw Chiller

Screw Style Chiller

In a screw style chiller, the compressor compresses the refrigerant, which increases its pressure and temperature. The compressed refrigerant is then cooled in a condenser, where it releases heat to the environment. The cooled refrigerant then flows through an expansion valve, which reduces its pressure and temperature. This allows it to absorb heat from the water or other fluid that needs to be cooled.

A screw style chiller is a type of chiller that uses a screw compressor to cool water or other fluids. It is a type of positive displacement compressor that compresses the refrigerant or coolant through two interlocking rotors that turn in opposite directions.

In a screw style chiller, the compressor compresses the refrigerant, which increases its pressure and temperature. The compressed refrigerant is then cooled in a condenser, where it releases heat to the environment. The cooled refrigerant then flows through an expansion valve, which reduces its pressure and temperature. This allows it to absorb heat from the water or other fluid that needs to be cooled.

The cooled water or fluid is then circulated through the system to cool the space or process that requires cooling. The process is repeated continuously, with the screw compressor compressing the refrigerant and the cooling cycle continuing.

Screw style chillers are commonly used in commercial and industrial settings, such as office buildings, hospitals, data centers, and manufacturing plants. They are known for their energy efficiency, low noise levels, and ability to handle high heat loads. They are also capable of providing precise temperature control, making them ideal for applications where temperature control is critical.
