Working principle of cooling mode

Principle:
The air conditioner absorbs heat from the room and uses refrigerant to transfer the heat energy
to the outdoor unit where it is discharged to the outdoor air. Total cooling capacity will increase
or decrease based on outdoor ambient temperature.
Anti-freezing protection
If the unit is running in the COOL mode, and the indoor coil temperature drops due to low indoor
air temperature conditions, the microcomputer will stop the compressor in order to protect the
unit.
