3.3 Key parts
3.3.1 Oil Separator
It is used to separate oil from high pressure & temperature gas refrigerant that is pumped out from compressor.
3.3.2 Gas-liquid separator
It is used to store the liquid refrigerant and oil, it can protect the compressor from liquid hammer.
3.3.3 Four-way valve (ST)
ST1: It is used to control the refrigerant flow from the left heat exchanger. When ST1 is OFF, the left heat exchanger is condenser
When ST1 is ON, the left heat exchanger is evaporator .
ST2: It is used to control the refrigerant flow from the right heat exchanger . When ST2 is OFF , the right heat exchanger is condenser ,
when ST2 is ON, the right heat exchanger is evaporator .
ST3: When the system is in cooling mode , it is ON , when the system is in heating mode or mixed mode , it is OFF .
3.3.4 EXV (Electromagnetic expansion valve)
a) Max. Open degree is 480 pulses.
b) Generally when system is electrified the EXV closes 700pulse first, then opens to 350 pulse and stand by. Then the unit is started,
it opens to the right pulse.
c) When the running outdoor unit receives OFF signal, the EXV of auxiliary unit will stop while main unit is running and auxiliary
unit is stopped at the same time. If all outdoor units are stopped, the EXV will close first, and then open to the pulse of stand-by.
3.3.5 SV2
It is for spraying a little liquid refrigerant to cool compressor down. Open when any compressor discharge temperature is higher than
100˚C.
3.3.6 SV4:
a) Oil return valve.
b) Opens after the DC inverter compressor has been run for 200 seconds and then closes 10 minutes later. (For the system has only
one outdoor unit).
c) Every 20 minutes, SV4 of each outdoor unit opens for 3 minutes. (For the system has more than one outdoor unit)
3.3.7 SV5
a) It is used for quick defrosting.
b) In defrosting mode, the opening of SV5 can cut the refrigerant flowing circle, so the defrosting process will takes less time.
c) In cooling mode and main cooling , it is always off.
3.3.8 Hi pressure sensor
To detect the discharge pressure of the compressor and to control the DC fan speed
3.3.9 Pressure switch
It is used to protect the system pressure ,when the pressure is higher than 4.5Mpa or lower than 0.05Mpa , the switch will work . Once
the pressure switch is open , the compressor will stop .

5.4.4 Power wire selection
Power wiring includes the main wire (a) connecting to branch box and the wire (b) between branch box and power facilities.
Please select the wire diameter according to the following requirement.
a) Diameter of main wire (a): depends on the total horse power (HP) of outdoor unit (See 5.4.3).
Example:
In system: (8HP×1 unit+8HP×1 unit+10HP×1 unit)
So totally 26HP → See 5.4.3 → size of wire is 25mm2 (within 20m)
b) Diameter of wire (b): depends on the number of combined outdoor unit.
If outdoor unit quantity ≤ 5, the wire (b) diameter selection is same as main wire (a) selection (See 5.4.3).
If outdoor unit quantity > 5, there will be 2 electric control boxes, the wire (b) diameter selection depends on the total horse power (HP)
of outdoor units connecting to each electric control box (See 5.4.3).
