Principle:
Air conditioner absorbs heat in the room and transmit to
outdoor and discharged, so that indoor ambient
temperature decreased. It's cooling capacity will decrease
by the increase of outdoor ambient temperature.
Anti-freezing Function:
If the units is running in COOL mode and in low
temperature, there will be frost formed on the heat
exchanger, when indoor heat exchanger temperature
decreased below 0 C, the indoor unit micro-computer will
stop compressor running and protect the unit.
