D.C. Inverter Multi-variable Modular
●When system compressor starts up, temp of discharge tube or casing
top in cooling mode is within 70~95 , and at least 10
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
pressure value;
●In heating mode, defrost temp1 is about 2
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
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.
●In heating mode, the opening angle of adjustable electronic expansion
valve varies within 120~480PLS.
Varies from 20Hz to 95Hz
●According to different operating freq. and different load, 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 normal if actual voltage varies 15v from the
calculated voltage.
Varies from 30Hz to 100Hz
●According to different operating freq. and different load, 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 normal if actual voltage varies 15v from the
calculated voltage.
