No Part Name Abbreviation Symbol Function
1 Inveter Compressor INV
This type of compressor uses a drive to control the
compressor motor speed to modulate cooling capacity.
2 Outdoor Fan Motor OFM
The outdoor air and the refrigerant to heat exchange
through the heat exchanger.
3
Outdoor Heat Exchanger
(Heat Exchanger -
Main (Outdoor unit))
OHX
(HX_M)
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.
4 Accumulator AC
It prevents liquid compression to separate the liquid
refrigerant flowing into the compressor.
5 Oil Separator OS
Separating the oil from the refrigerant discharged from the
compressor, and sends the separated oil to the compressor.
6 Reservoir RE
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.
7
Intercooler
(Heat Exchanger-Intercooler)
IC (HX_IC)
The heat exchange between the refrigerant in the pipe and
passing through the EVIEEV.
8 IPM Cooler IPMC
By heat exchange between the liquid refrigerant and IPM,
prevent overheating of IPM and protect the system.
9
High Pressure Sensor
(Pressure Sensor-High)
HPS (PS_H)
By measuring the pressure (high pressure) of the
compressor discharge, protects the pressure control &
system.
10
Low Pressure Sensor
(Pressure Sensor-Low)
LPS (PS_L)
By measuring the pressure (low pressure) of the compressor
suction, protects the pressure control & system.
11
High Pressure Switch
(Pressure Switch-High)
HPSW (PW_H)
By stopping the system immediately to the high pressure
exceeds the set pressure and protects the system.
12
Main EEV
(Electronic Expansion Valve-Main)
E_M
By controlling the amount of refrigerant during the heating
operation and it controls the superheat.
13
EVI EEV
(Electronic Expansion Valve-EVI)
E_EV (E_EVI)
By controlling the amount of refrigerant passing through
the intercooler.
14
EVI Sol. Valve
(Solenoid valve-EVI)
V_ES (V_EVI)
"When the compressor stops, close the valve.
The refrigerant having passed through the EVI EEV prevents
the inflow of the stopped compressor."
15
EVI Bypass Valve
(Solenoid valve-EVI Bypass)
V_EB
In Vapor/Flash Injection Requires close the valve to flow the
refrigerant to the compressor.
16
Hot Gas Bypass Valve
(Solenoid valve-Hot Gas Bypass)
V_HG
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.
17
Hot Gas Bypass Valve 2
(Solenoid valve-Hot Gas Bypass 2)
V_HG2
To open the valve when the cooling operation alone. Convert
the high-pressure gas pipe to the low pressure gas pipe. (HR
Only)
18
Outdoor EEV Valve
(Solenoid valve-Main EEV)
V_OE (V_ME)
Close the main valve in the cooling operation and to control
the amount of refrigerant in the Main EEV. (HR Only)
