This air-cooled chiller working diagram illustrates the flow and major components of a refrigeration system designed for cooling water. It includes the compressor (1) which compresses refrigerant gas, the high and low pressure gauges (2, 13) and protectors (3) to monitor system pressure, the condenser (4) where refrigerant releases heat to air, and the high-pressure accumulator (5) for liquid refrigerant storage. The system also features valves for flow control such as the solenoid valve (10), expansion valve/capillary (11), and various shut-off valves (6, 8, 16, 17). The evaporator (12) cools the water circulated by the frozen water pump (15), while the fan (14) aids heat dissipation. Additional components include the liquid mirror (9), filter dryer (7), water supply valve (19), tank water floating ball valve (20), and drain valve (21), collectively ensuring efficient and safe chiller operation.
