●When the system compressor starts
running and in normal cooling mode,
the air discharge pipe or shell top
temperature is between 70°C and
95°C, more than 10°C higher than the
saturation temperature corresponding
to the high system pressure; in normal
heating mode, the air discharge pipe or
shell top temperature is between 65°C
and 90°C, more than 10°C higher than
the saturation temperature
corresponding to the high system
pressure.

of the
defrosting
temperature
sensor
°C
●When the system operates in cooling
mode, the temperature of the
defrosting temperature sensor is 5°C to
11°C lower than the high system
pressure;
●When the system operates in heating
mode, the difference between the
temperature of the defrosting
temperature sensor and th
e low system
pressure is about 2°C.

High system
pressure
°C
●The normal high system pressure
value is between 20°C and 55°C.
Based on the change of the ambient
temperature and operating capacity of
the system, the high system pressure
value is 10°C to 40°C higher than the
ambient temperature, and the higher
the ambient temperature, the smaller
the temperature difference between the
two is;
●In cooling mode, when the ambient
temperature is between 25°C and
35°C, the high system pressure is
between 44°C and 56°C;
●In heating mode, when the ambient
temperature is between –5°C and
10°C, the high system pressure is
between 40°C and 56°C.

Low system
pressure
°C
●In cooling mode, when the ambient
temperature is between 25°C and

between 0°C and 8°C;
●In heating mode, when the ambient
temperature is between –5°C and
10°C, the low system pressure is
between –15°C and 5°C.
