3. Component introduce
Component name Main function
DC Inverter
DC inverter Compressor :
Compressor work frequency range is 20~120 Hz.
HP Switch
High Pressure Switch:
When refrigerant high pressure value over the target pressure
value , switch valve is disconnected, signal is interrupted ,then stop
running to protect the refrigerant system
OS
Oil Separator:
To separate refrigeration oil and high pressure refrigerant
Filter
Filter impurities to avoid blockage of electronic expansion valve
SV1
Unload Valve
SV5/ SV6
Enhance vapor injection Valve
HP sensor
High Pressure Sensor:
Detecting refrigerant system high pressure value
4-way valve
Change the refrigerant flow direction to achieve cooling or heating
mode
Plate Heater
Sub-cooler:
5.5
℃
sub-cooling by plate heat exchanger make sure liquid
refrigerant flow into evaporator Instead of gas-liquid refrigerant flow
into evaporator , reduce Airflow noise and temperature fluctuation
and support long piping length
SV3
Sub-cooling Valve
Refrigerant Cooling
Well cooled by refrigerant, ensuring the long life time of the PCB
