No Part Name Abbreviation Symbol Function
1 Invet er Compressor INV
This type of compressor uses a drive to control the compressor motor
speed to modulate cooling capacity.
2
Outdoor Heat Exchanger
(Heat Exchanger - Main (Outdoor unit))
HX_PHE
By heat exchange of the Water air and the refrigerant thereby condensing
the refrigerant during a cooling operation
and evaporating the refrigerant during a heating operation.
3Accumulator AC
It pr events liquid compression to separate the liquid refrigerant owing
into the compr essor.
4 Oil Separator OS
Separating the oil from the r efrigerant discharged from the compressor,
and sends the separat ed oil to the compressor.
5 Reservoir RE
When cooling operation stores the liquid refrigerant, when heating
operation and stor es the gaseous refrigerant.
When the refrigerant ow heating and cooling operation to eliminate
imbalanc es .
6
Intercooler
(Heat Exchanger - Intercooler)
IC (HX_IC)
The heat exchange between the r efrigerant in the pipe and passing
through the EVIEEV.
7IPM Cooler IPMC
By heat exchange between the liquid refrigerant and IPM, prevent
overheating of IPM and pr ot ect the system.
8
High Pressur e Sensor
(Pressur e Sensor-High)
HPS (PS_H)
By measuring the pr essur e (high pressure) of the compressor discharge,
protects the pressure control & system.
9
Low Pressure Sensor
(Pressur e Sensor-Low)
LPS (PS_L)
By measuring the pr essur e (low pressure) of the compressor suction,
protects the pressure control & system.
10
High Pressur e Switch
(Pressur e Switch-High)
HPSW (PW_H)
By stopping the system immediat ely to the high pressure exceeds the set
pressure and protects the system.
11
Main EEV
(Electronic Expansion Valve-Main)
E_M
By controlling the amount of refrigerant during the heating operation and
it controls the superheat.
12
EVI EEV
(Electronic Expansion Valve-EVI)
E_EV (E_EVI) By controlling the amount of refrigerant passing thr ough the intercooler
13
EVI Sol. Valve
(Solenoid v
alve-EVI)
V_ES (V_EVI)
"When the compressor stops , close the valve.
The r efrigerant having passed thr ough the EVI EEV prevents the inow of
the stopped compr essor."
14
EVI Bypass Valve
(Solenoid valve-EVI Bypass)
V_EB
In Vapor/Flash Injection
Requires close the valve to ow the refrigerant to
the compressor.
5
Hot Gas Bypass Valve
(Solenoid valve-Hot Gas Bypass)
V_HG
When high pressure is abnormally high, when low pressur e is abnormally
low, Opening the valve
by-pass the high-pressure gas to the low pressur e
pipe to protect the system.
16
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 pr essur e gas pipe. (HR Only)
17
Liquid tube Valve
(Solenoid valve-Liquid tube)
V_L Valve is Closed to prevent refrigerant from accumulating in receiver tank.
18
MainCooling Valve
(Solenoid
valve - Main Cooling)
V_MC
Opening the valve during cooling operation and sends a high-pr essure
gas into the indoor unit for the heating operation. (HR Only)
19
Accumulator Oil Return Valve (Solenoid
valve-Accumulator Oil Return)
V_AR
Opening the
valve during operation and sends the oil which accumulates
in the lower liquid separat or to the compressor.
20
Hot Gas Charging Valve
(Solenoid valve-Hot Gas Charging)
V_HCValve is opened when high pressur e is low in cooling operation.
