System Description
Mechanical Refrigeration Device Component
Control Panel Device Component
Dual Pressure Switch
-
Dual Pressure Switch (DPS) consists of high low pressure switch and low pressure switch in a case. On contacts part like as bellows, lever and contact setting screw, these contacts is a fair of 2. High pressure control is return type HPS (high low pressure switch), this switch is used when abnormal raising of compressor outlet (ex. clogging of tube, freezing of expansion valve), and LPS (low pressure switch) is used when abnormal down of intaking pressure.
-
When all pressure of intake and emit are not normal, the system can not work. In other words, on piping and tubing part in refrigeration system this device is used in control of compressor working/stop. it is just for safety device.
