is 65-80°C, which is more than 10°C higher than the
saturation temperature corresponding to the system
high-pressure.
3
Defrosting
temperature
°C
●When the system runs for cooling, the defrosting
temperature is 5-11°C lower than the system
high-pressure value.
●When the system runs for heating, the defrosting
temperature is 2°C higher or lower than the system
low-pressure value.
4
System
high-pressure
°C
●The normal system high-pressure value is
20-55°C. With the change of environment
temperature and system operation capacity, the
system high-pressure value is 10-40°C higher than
the environment temperature. The higher the
environment temperature, the less the temperature
difference.
●When the system runs for cooling with the
environment temperature being 25-35°C, the system
high-pressure value is 44-53°C.
●When the system runs for cooling with the
environment temperature being -5 to 10°C, the
system high-pressure value is 40-52°C.
5
System
low-pressure
°C
●When the system runs for cooling with the
environment temperature being 25-35°C, the system
low-pressure value is 0-8°C.
●When the system runs for cooling with the
environment temperature being -5 to 10°C, the
system low-pressure value is -15 to 5°C.

valves
PLS
●During the cooling operation, the heating electronic
expansion valves always remain at 480 PLS.
●During the heating operation, the adjustable
electronic expansion valves change between 120
and 480 PLS.
7
Operation
frequency of
inverter
compressor
Hz
●The operation frequency of inverter compressor 1
changes between 20 and 95 Hz.
●The operation frequency of inverter compressor 2
changes between 30 and 100 Hz.
8
Current of
inverter
compressor
A
●According to different operation frequencies and
loads, the current of inverter compressor 1 changes
between 7 and 25 A. The current of inverter
compressor 2 changes between 7 and 20 A.
9
IPM module
temperature of
inverter
compressor
°C
●When the environment temperature is lower than
35°C, the temperature of the IPM module is lower
than 80°C. The highest temperature is not higher
than 95°C.
10
Driver bus line
voltage of
inverter
compressor
V
●The normal bus line voltage is 1.414 times larger
than the power voltage. For example, if the
three-phase power voltage is 390 V, the bus line
voltage after current rectification is 390 V×1.414 =
551 V. It is normal if the difference between the
actual test value and the calculation value is within
15 V.

●With the adjustment of system pressure, the fans
run between 0 and 65 Hz.
