<In cooling/dry operation>
(Prevent-freezing control for indoor heat exchanger)
In cooling/dry operation, the sensor of indoor heat
exchanger detects evaporation temperature and
controls the compressor speed so that temperature of
the heat exchanger does not exceed the specified
value.
Description
1) When temperature of the indoor
heat exchanger drops below 5°C,
the compressor speed is
reduced. (P zone)
2) When temperature of the indoor
heat exchanger rises in the
range from 6°C to under 7°C, the
compressor speed is kept.
(Q zone)
3) When temperature of the indoor
heat exchanger rises to 7°C or
higher, the capacity control
operation returns to the usual
control in cooling operation.
