WebThe water-cooled chiller operates by circulating water or other fluids through the evaporator. The evaporator cools the fluid by transferring heat to the refrigerant. The refrigerant then flows to the compressor, where it is compressed and heated. The hot, high-pressure gas flows to the condenser, where it releases heat into the environment. WebRunning a single system on the chiller and checking the temperature differential across the evaporator (return minus leaving water temp) is also a quick means for checking for low flow, if the flow cannot be measured using a flow meter or there is doubt about the accuracy of the flow pressure drop measurement. Web43.3ºC]). This chiller can also operate as a cooling-only chiller at normal condensing temperature.
