Major Function
Operated up to 20Hz~100Hz by inverter operation. Pressurize high
temperature, low pressure refrigerant to high temperature, high
pressure.
Adjust outdoor wind quantity while varying the outdoor fan by 0~65Hz.
Adjust flow quantity depending on overheat level of refrigerant in the
outdoor side in heat status.
Adjust flow quantity depending on overheat level of the outlet of the
excessive cold heat exchanger in cold status.
Stabilize the system by high pressure gas to the low pressure part
after opening when bypass and low pressure of refrigerant rapidly
reduces to less than the valve valve.
Cut-off the outdoor heat exchanger with the evaporator or condenser
depending on operation of the indoor unit.
Used to obtain flow quantity of refrigerant in cold condition.
Mechanically stop the compressor where the compressor rises to the
high pressure limit valve due to abnormal operation.
Measure high pressure of the system.
Measure low pressure of the system.
.
Used for control by measuring temperature of the outdoor heat
exchanger.
Used for protecting and controlling the compressor by measuring
discharger temperature.
Measure outdoor temperature.
Used for controlling super heat level by measuring refrigerant
temperature of the suction pipe.
Used for controlling sub cool level by measuring refrigerant
temperature of the liquid pipe.
Used for controlling super heat level by measuring outlet
temperature of the subcooler circuit.
Used for controlling super heat level by measuring outlet
temperature of the subcooler circuit.
Prevent reverse flow of high pressure refrigerant into the compressor.
