Refrigerating Float Valves

without comments

These valves are divided into high-side float valves and low-side float valves. They are employed to control the refrigerant flow to a flooded-type liquid cooler. A high-side float valve is located on the high-pressure side of the throttling device. It is used in a refrigeration system with a single evaporator, compressor, and condenser. A low-side float valve is particularly located on the low-pressure side of the throttling device and may be used in refrigeration systems with multiple evaporators. In some cases a float valve operates an electrical switch controlling a solenoid valve which periodically admits the liquid refrigerant to the evaporator, allowing the liquid level to fluctuate within preset limits.
