Working principle and special functions for cooling
Principle:
The air conditioner transfers heat from the indoor area to the outdoor area, thus
reducing the indoor room temperature, using heat pump technology.
Anti-freezing function:
In COOL mode under low ambient temperature, frost will form on the heat exchanger.
When the indoor heat exchanger temperature decreases to below 0
℃ , the indoor unit
microcomputer will stop the compressor from running. This is normal and is important to
protect the compressor and prolongs the life of the air conditioner.
Working principle and special functions for heating
Principle:
*
The air conditioner transfers heat from outdoor area to the indoor area, thus increasing
the indoor room temperature using heat pump heating technology.
*
In extreme cold temperature, the condenser will require defrosting regularly. You may
need to use alternative heating equipment.
Defrosting:
*
When outdoor temperature is low but high humidity, frost will form on outdoor unit that
will affect the heating, resulting in the auto defrost function where the heating will stop
for 8-10mins.
*
During the auto defrosting, the fans of indoor and outdoor unit will stop.
*
During the defrosting, the indoor indicator flashes, the outdoor unit may emit
vapour. This is normal and is not a malfunction.
*
Once defrosting is completed, the heating will recover automatically.
Anti-cool wind function:
In the “Heat” mode, the indoor fan operation will be delayed to prevent cold air being
expelled for additional comfort.
It is apparent during the start of the heating mode, upon completion of the Auto
Defrosting and heating during very low temperature.
It is normal for the indoor unit to expel low air flow and the louver to rotate to a certain
position:
1. In “Heat” mode, upon starting, the compressor running is delayed.
2. In “Heat” mode, upon reaching the set temperature, the compressor stops
running for about 1 min.
