DC Inverter Multi VRF System User Manual
Unit Reference
℃
●When compressor starts, discharge temp in cool
mode is within 70~105℃ and at least 10℃ higher
than the high pressure saturation temp;
℃
●As for temp in heat mode, it is within 65~90℃
and at least 10℃ higher than the high pressure
saturation temp.
●In cool mode, defrosting temp is 4~10℃ lower
than system's high pressure value;
℃
●In heat mode, defrosting temp is about 2 ℃
different from system's low pressure value.
●In cool mode, the normal high pressure value is
within 20 ℃~55℃. According to the change of
ambient temp and system's operating capacity, the
high pressure value will be 10℃~30℃ higher than
ambient temp. The higher ambient temp is, the
smaller temp difference is. If ambient temp is
℃
25~35℃ in cool mode, system's high pressure
value will be within 44~53℃.
●In heat mode, if ambient temp is above -5℃,
system's high pressure value is within 40~52℃. If
ambient temp is low and many IDUs are turned on,
the high pressure will be lower.
●When ambient temp in cool mode is 25~35℃, the
low pressure value is 0~8℃.
℃
●When ambient temp in heat mode is above -5℃,
the low pressure value is -15~8℃.
●In cool mode, the thermal electronic expansion
PL valve remains 480PLS.
S ●In heat mode, the adjustable opening angle of
EXV is 40~480PLS.
HZ Changes in 10Hz~80Hz.
When compressor works normally, the current is
A
no more than 18.4A.
When ambient temp is below 35℃, IPM temp is
lower than 80℃ and the highest temp won't be
℃
above 95℃.
Changes in 0~49Hz according to system's
HZ
pressure.
——
℃
●According to ambient temp, for a same IDU in
cool mode, the inlet temp will be 1℃~7℃ lower
℃
than the outlet temp, and 4~9℃ higher than the
low pressure value.
●For a same IDU in heat mode, the inlet temp will
℃
be 10℃~20℃ lower than the outlet temp.
●In cool mode, the opening angle of indoor EXV
PL varies within 70~480PLS.
S ●In heat mode, the opening angle of indoor EXV
varies within 70~480PLS.
Number of IDUs detected by software is the same
—
with the actual number. No communication error.
Indoor unit can drain water out completely and
smoothly. Condensate pipe has no backward
— slope of water; Water of outdoor unit can be
drained completely through drainage pipe. No
water drop from unit base.
Compressor and indoor/outdoor fan motor do not
—
have strange noise. Unit can operate normally.
