Indoor Unit Fan Control
Outline
During compressor start and stop control, the indoor fan will receive instruction from the outdoor unit
in order to protect the compressor from receiving liquid and to assure a smooth compressor start up:
Q
Indoor fan control before compressor stop
Q
Indoor fan control during compressor stop
Q
Indoor fan control before compressor startup
Q
Indoor fan control at compressor startup
Before compressor
stop
After thermostat off or remote-controller signal off has been sent from the outdoor unit to the indoor
unit, the compressor will keep on running for a period of time in order to execute the "residual pump
down operation". During this pump down operation, the indoor fan will keep on operating.
Purpose:
Q
Cooling: Minimize the remaining refrigerant amount in indoor unit heat exchanger
Q
Heating: Lower the high pressure by avoiding high temperature build up around the indoor unit heat
exchanger.
