Working principle and special functions for cooling
Principle:
Air conditioner absorbs heat in the room and transmit to outdoor and discharged, so that
indoor ambient temperature decreased, its cooling capacity will increase or decrease by
outdoor ambient temperature.
Anti-freezing function:
If the unit 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
℃
, the
indoor unit microcomputer will stop compressor running and protect the unit.
Working principle and special functions for heating
Principle:
*
Air conditioner absorbs heat from outdoor and transmits to indoor, in this way to increase
room temperature. This is the heat pump heating principle, its heating capacity will be
reduced due to outdoor temperature decrease.
*
If outdoor temperature becomes very low, please operate with other heating equipments.
Defrosting:
When outdoor temperature is low but high humidity, after a long while running, frost will
form on outdoor unit, that will effect the heating effect, at this time, the auto defrosting
function will act, the heat running will stop for 8-10mins.
*
*
