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)
Opening the valve during cooling operation and sends a high-pressure
gas into the indoor unit for the heating operation. (HR Only)
Opening the valve during operation and sends the oil which accumulates
in the lower liquid separator to the compressor.
