The gauge-switch of pressure К/В - a design and a functioning principle
Principle of functioning of the gauge-switch of pressure К/В
The pressure gauge-switch is included in a line of a high pressure of a receiver-dehumidifier and serves for compressor K/V switching-off at excessive increase or pressure drop in a line.
So pressure lowering in высоконапорной more low 177 кПа the gauge-switch perceives lines as a signal of development of leaks of a coolant and stops the compressor in order to avoid irreversible losses of a working body, the high pressure in a line is excessive (from above 2940 кПа) can lead to destruction of components of a refrigerator path and also demands compressor switching-off. |
