defrosting temperature
sensor
When the system is running in cooling
mode, the temperature of defrosting
temperature sensor is 5~11
41~51.8
lower than system high pressure;
When the system is running in heating
mode, the temperature difference
between the defrosting temperature
sensor and the system low pressure is
about 2

● The normal high pressure value of the
system is 20

. According to the change of
ambient temperature and the change of
operating capacity of the system, the
high pressure value of the system is
10
50
~40
104
higher
than the ambient temperature. The
higher the ambient temperature, the
smaller the temperature difference;
When the unit operating in the cooling
mode at the ambient temperature of
25~35
77~95
, the system high
pressure value is 44~56
111.2~132.8
;
When the unit operating in the heating
mode at the ambient temperature of -
5~10
23~50
, the system high
pressure value is 40~56
104~132.8
;
