Function
This type of compressor uses a drive to control the
compressor motor speed to modulate cooling capacity.
The outdoor air and the refrigerant to heat exchange
through the heat exchanger.
By heat exchange of the outdoor air and the refrigerant
thereby condensing the refrigerant during a cooling
operation and evaporating the refrigerant during a heating
operation.
It prevents liquid compression to separate the liquid
refrigerant flowing into the compressor.
Separating the oil from the refrigerant discharged from the
compressor, and sends the separated oil to the compressor.
When cooling operation stores the liquid refrigerant, when
heating operation and stores the gaseous refrigerant.
When the refrigerant flow heating and cooling operation to
eliminate imbalances.
The heat exchange between the refrigerant in the pipe and
passing through the EVIEEV.
By heat exchange between the liquid refrigerant and IPM,
prevent overheating of IPM and protect the system.
By measuring the pressure (high pressure) of the
compressor discharge, protects the pressure control &
system.
By measuring the pressure (low pressure) of the compressor
suction, protects the pressure control & system.
By stopping the system immediately to the high pressure
exceeds the set pressure and protects the system.
By controlling the amount of refrigerant during the heating
operation and it controls the superheat.
By controlling the amount of refrigerant passing through
the intercooler.
"When the compressor stops, close the valve.
The refrigerant having passed through the EVI EEV prevents
the inflow of the stopped compressor."
In Vapor/Flash Injection Requires close the valve to flow the
refrigerant to the compressor.
When high pressure is abnormally high, when low pressure
is abnormally low, Opening the valve by-pass the high-
pressure gas to the low pressure pipe to protect the system.
To open the valve when the cooling operation alone. Convert
the high-pressure gas pipe to the low pressure gas pipe. (HR
Only)
Close the main valve in the cooling operation and to control
the amount of refrigerant in the Main EEV. (HR Only)
