2.2Working Principle and Special Functions for Heating
(Heat Pump Model Only)
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.
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 oC, the indoor unit
Principle:
1.Air conditioner absorbs heat from the outdoor and transmit to indoor and evaporated, so that indoor temperature increased. Its heating capacity will decrease by the decrease of outdoor ambient temperature.
2.If outdoor temperature got lower, please operate with other heating ventilating equipments.
Defrosting:
1.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, and the heat running will stop for
2.During the auto defrosting function, both the fan motors of indoor unit and outdoor unit will stop operate.
3.During the defrosting function, the indoor indicator flashes and the outdoor unit may emit vapor. This is due to the defrosting, it is not malfunction.
4.After defrosting finished, the heating will recover automatically.
