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 termperature, 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:
The unit absorbs heat from outdoor air, carrys and emits the heat in indoors
to make indoor air temperature higher. Its heating capacity would be lower
according to the low weather of outdoor ambient.
This heating air circulation system can enhance the indoor temperature
in a short while.
If outdoor temperature got lower, please operate with the other heating ventilating
equipments.
Defrosting:
When outdoor temperature is low but with high humidity, after a long while running,
frost will form on outdoor unit, that will affect the heating effect, at this time,
the auto defrosting function will act, the heat running will stop for 8-10mins.
During the auto defrost, the fan motors of indoor unit and outdoor unit will stop.
During the defrost, the indoor indicator flashes, the outdoor unit may emit vapor.
This is due to the defrosting, it isn't malfunction.
After defrost finished,the heating will recover automatically.
Anti-freezing function:
In "HEAT" mode, under the following three states, if indoor heat exchanger didn't reach certain
temperature, indoor fan would not operae to prevent blowing out cool air:
(Within 3mins)
1.Heating starts. 2.Afer Auto defrosting finished. 3.Heating under the low temperature.
The conditions of unit can't normally run
The following temperature range protection device may act, that may cause stop running.
