Component
Function / remark
1a
Flare connection
See pipe connection diameter.
2a
Liquid stop valve
The liquid stop valve is used as shut-off valve in case of a pump-down.
2b
Liquid stop valve
with service port
3
Gas stop valve with
service port
The gas stop valve is used as shut-off valve in case of a pump-down.
4
Compressor
The compressor can restart after 3 min from last stop.
5a
Capillary tube
The capillary tube allows pressure equalization during a compressor OFF-cycle.
5b
The capillary tube expands the liquid to enable evaporation in the evaporator.
6
Electronic expan-
sion valve
The expansion valve expands the liquid to enable evaporation in the evaporator. The opening
degree is controlled to obtain the optimum discharge temperature.
7
Heat exchanger
The heat exchanger is of the multi louvre fin type. Hi-X -tubes and coated waffle louvre fins are
used.
8
Filter
The filter is used to collect impurities, which may enter the system during installation and is also
used to avoid blockage of the capillaries and other fine mechanical parts of the unit.
9
Liquid receiver
The liquid receiver is used to make sure only completely liquefied refrigerant is sent to the expan-
sion valve. It is also used as a container in which surplus refrigerant is stored.
10
Check valve with
service port
The check valve allows you to connect a gauge.
11
Low-pressure sen-
sor (RZQ71)
The low pressure sensor is used to control the unit's actuators (expansion valve, frequency,...)
Low-pressure switch
(RZQ100~140)
The low-pressure switch stops the operation of the unit when the pressure becomes abnormally
low.
12
High-pressure
switch
The high-pressure switch stops the operation of the unit when the pressure becomes abnormally
high.
13
Propeller fan and fan
motor
The propeller fan creates air displacement across the heat exhanger.
14a
One-way valve
The one-way valve is used to force the refrigerant liquid to flow through the receiver and the
expansion valve in the same direction both in cooling and heating.
14b
The one-way valve is used to release overpressure in the liquid receiver during stand-still.
15
4-way valve
(reversing solenoid
valve)
The 4-way valve is used to select refrigerant flow in cooling or heating mode.
When the 4-way valve switches from ON to OFF, a timer starts counting up to 150 as soon as the
cooling or defrosting operation is stopped. This delay time is to eliminate the switching sound.
16
Muffler
The muffler is used to absorb the refrigerant noise from the compressor.
17
Solenoid valve
P
Y1S: Capacity control solenoid valve
P
Y3S: Liquid injection solenoid valve
P
SV: Solenoid valve (Purge liquid receiver)
18
Thermistor
P
R1T: Air thermistor
P
R2T: Coil thermistor
P
R3T: Discharge pipe thermistor
19
Branch pipe
