Refrigerating Cycle Diagram
6
13. 4-way valve (4-W/V)
13.
It enables the change between cooling and heating by reversing the flow direction of refrigerant.
14. Electronic expansion valve (EEV)
13.
By sensing suction temperature and low pressure, controls the suction super heat and
13.
mass flow of refrigerant.
15. Check valve (C/V)
13.
To reduce the loss of pressure at the electronic expansion valve while cooling and to prevent
13.
the over-load of the compressor.
16. Suction sensor (SUC.S)
13.
To control EEV for optimized suction super heat to control over-heating at the electronic expansion
13.
valve by the temperature of the compressor suction part when heating.
17. Oil sensor (OIL.S)
13.
To control EEV against liquid back and low dilution of oil to protect the compressor by measuring
13.
the temperature of oil used for controlling sump at low temperature in cooling / heating mode.
18. Temperature sensor (FDTS, Fixed Discharge Temperature Sensor)
13.
It is the means to measure the refrigerant temperature of compressor outlet which is used as the data
13.
for control of fixed compressor.
19. Low pressure sensor (LPSO)
13.
By measuring the low pressure, any abnormal system status is determined and the low-pressure
13.
protection control is performed.
20. High pressure sensor (HPSO)
13.
By measuring the high pressure, any abnormal system status is determined and the high-pressure
13.
protection control is performed.
21. Oil separator
13.
This device recovers oils emitted from the compressor and returns it to the compressor again.
