●When system compressor starts up, temp of discharge
℃
tube or casing top in cooling mode is within 70~95℃ , and
at least 10℃ higher than system high pressure saturation
℃
temp; Temp in heating mode is within 65℃~80℃ , and at
least 10℃ higher than system high pressure saturation
℃
temp.
●When inverter compressor starts but inverter
compressor 2 stops, the discharge tube temperature of
℃
inverter compressor 2 is almost the same with ambient
temp.
●In cooling mode, defrost temp1 is 5~11℃ lower than
system high pressure value;
℃
●In heating mode, defrost temp1 is about 2℃ different
from system low pressure value.
●System's normal high pressure value is within 20℃
~25℃. According to the change in ambient temp and
system operational capacity, system's high pressure value
is 10 ~40℃ higher than ambient temp The higher ambient
℃
temp is, the smaller temp difference is.
●When ambient temp is 25~35℃, system's high pressure
value in cooling mode is 44~53℃.
●When ambient temp is -5~10℃, system's high pressure
value in heating mode is 40~52℃.
●When ambient temp is 25~35℃, system's low pressure
value in cooling mode is 0~8℃.
℃
●When ambient temp is -5~10℃, system's low pressure
value in heating mode is -15~5℃.
●In cooling mode, heating electronic expansion valve
remains 480PLS.
PLS
●In heating mode, the opening angle of adjustable
electronic expansion valve varies within 120~480PLS.
Hz Varies from 20Hz to 95Hz
●According to different operating freq. and different load,
A
current will vary from 7A to 25A.
●When ambient temp is lower than 35℃, IPM temp is
℃
below 80℃. Highest temp won't be above 95℃.
●Normal bus voltage is 1.414 times of power voltage. For
example, if 3-phase power voltage is 390v, then the bus
voltage after rectification is: 390v X 1.414=551v. It's
V
normal if actual voltage varies 15v from the calculated
voltage.
Hz Varies from 30Hz to 100Hz
●According to different operating freq. and different load,
A
current will vary from 7A to 20A.
●When ambient temp is lower than 35℃, IPM temp is
℃
below 80℃. Highest temp won't be above 95℃.
●Normal bus voltage is 1.414 times of power voltage. For
example, if 3-phase power voltage is 390v, then the bus
voltage after rectification is: 390v X 1.414=551v. It's
V
normal if actual voltage varies 15v from the calculated
voltage.
