DVI compressor coupled with vapor injection controls the capacity 10 to 100% of its
capacity.
It enhances cooling and heating performance and COP with using vapor injection.
FVI compressor coupled with vapor injection is fixed compressor. It enhances cooling,
heating performance and COP with using vapor injection.
|t is used for variation of digital compressor's capacity. When the valve is open, the DVI
compressor keeps the unloading state, otherwise loading state.
It measures the temperature of compressor outlet. The main function of it is to protect
compressor from overheating.
It separates oil and refrigerant discharged from the compressor and returns the oil into
compressor again.
It protects the system from abnormal high pressure. (Open : 4.1Mpa, Close : 3.5 Mpa)
When the suction pressure becomes abnormal low pressure, it opens.
During the oil balance operation, it makes high pressure for the shell of compressor
The main function of it controls the capacity of compressor in pursuit of target of high
pressure in heating operation by measuring the value of the system.
It enables to change operating mode into cooling and heating mode.
It measures the temperature of ambient.
It has application to know subcooling and the complete point of defrost.
It controls the amount of refrigerant entering outdoor's heat exchanger in heating
operation.
When the compressor is overheating, it opens to make discharge temperature low.
It enables to secure sufficient subcooling and control the amount of vapor entering into
vapor port of compressor.
Through turbo intercooler, heat is exchanged each other between saturated liquid
refrigerant and a little expanded refrigerant.
These temperature sensors enable to control EVI EEV's step to secure superheat.
It is used to know subcooling.
(Subcooling = The saturated temp. of high pressure - Liquid tube temp.)
This valve closes during application of vapor injection.
This is applied to know superheat in heating mode with the low pressure sensor.
Ambient air temperature sensor (Tair)
When oil balance operation happens, this valve opens.
The main function of it is to control the capacity of compressor in pursuit of target of low
pressure in cooling operation by measuring the low pressure.
With checking sump temperature of compressor, it prevents the compressor from liquid
back and overheating.
While the oil balance is operating, it make a self-diagnosis of the oil valve.
In order to prevent outdoor heat exchanger from refrigerant accumulation in main cooling
operation, this valve closes, otherwise Main EEV controls the amount of refrigerant.
