The refrigerant is compressed in the compressor and flows through the discharge line as a gas to the condenser. There it gives up its heat as it condenses to a liquid in the condenser.
An electronic hot gas bypass valve is used to control cooling capacity during intermittent or partial load conditions. This feature contributes substantially to chiller longevity by eliminating excessive cycling of the compressor and providing close temperature control.
