Compressor
discharge temp
℃
(
℉
)
●When compressor starts, discharge
temp in cool mode is within 70~105
℃
(158~221
℉
) and at least 10
℃
(50
℉
)
higher than the high pressure
saturation temp;
●As for temp in heat mode, it is within
65~90
℃
(149~194
℉
) and at least
10
℃
(50
℉
) higher than the high
pressure saturation temp.
3 Defrosting temp
℃
(
℉
)
●In cool mode, defrosting temp is
4~10
℃
(39~50
℉
) lower than system’s
high pressure value;
●In heat mode, defrosting temp is
about 2
℃
(36
℉
) different from
system’s low pressure value.

(

●In cool mode, the normal high
pressure value is within 20
℃
~55
℃
(68~131
℉
). According to the change
of ambient temp and system’s
operating capacity, the high pressure
value will be 10
℃
~30
℃
(50~86
℉
)
higher than ambient temp. The higher
ambient temp is, the smaller temp
difference is. If ambient temp is
25~35
℃
(77~95
℉
) in cool mode,
system’s high pressure value will be
within 44~53
℃
(111~127
℉
).
●In heat mode, if ambient temp is
above -5
℃
(23
℉
), system’s high
pressure value is within 40~52
℃
(104~126
℉
). If ambient temp is low
