(Prevent-freezing control for indoor heat exchanger)
In cooling/dry operation, the sensor of indoor heat ex-
changer detects evaporation temperature and controls the
compressor speed so that temperature of the heat ex-
changer does not exceed the specified value.

compressor speed so that temperature of the heat ex-
changer 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)
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)
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.
(R zone)
higher, the capacity control
operation returns to the usual
control in cooling operation.
(R zone)
1) When temperature of the indoor
heat exchanger rises in the
range from 50°C to 55°C, the
compressor speed is kept.
(Q zone)
range from 50°C to 55°C, the
compressor speed is kept.
(Q zone)
When temperature of the indoor
heat exchanger drops in the
range from 46°C to under 55°C,
the compressor speed is kept.
(Q zone)
heat exchanger drops in the
range from 46°C to under 55°C,
the compressor speed is kept.

2) When temperature of the indoor
heat exchanger rises to 55°C or
higher, the compressor speed is
reduced. (P zone)
higher, the compressor speed is
reduced. (P zone)
3) When temperature of the indoor
heat exchanger does not rise to
50°C, or when it drops below to
46°C, the capacity control
operation returns to the usual
control in heating operation.
(R zone)
50°C, or when it drops below to
46°C, the capacity control
operation returns to the usual
control in heating operation.
