The compressor contactor closes and the condenser fan motor and the compressor turns on. This occurs concurrently because the compressor contactor controls each the compressor and the condenser fan motor. this is essential due to the fact if the compressor contactor pulls in or engages and the fan doesn’t begin however the compressor does then the technician knows there is a hassle with the condenser fan motor and vice versa. If neither starts Heat Pump Installer Auckland but the contactor is pulled in then the technician knows there’s either a trouble with the contactor passing voltage throughout the contacts or a power hassle. If the contactor does not pull-in then the tech is aware of there is a control trouble.
Condenser – Air Conditioner – heat Pump Fan Motor
Condenser Fan Motor
at the equal time the compressor contactor is doing its task the blower fan relay closes (from the “G” touch in the thermostat) and energizes the blower fan. whilst the compressor gets the refrigerant transferring through the refrigeration device the fan starts shifting air through the duct machine and across the evaporator coil.
when the thermostat satisfies the “Y” and the “G” contacts in the thermostat open de-energizing the compressor contactor and the fan relay. The compressor and condenser fan motor de-energize and forestall operation. The fan, in heating and cooling mode (no matter what sort of warmness you’ve got) will remain on because of a time delay in the air handler.that is to deplete any cool or hot air left inside the duct machine. It adds performance to the machine and uses any residual strength left within the machine. In heating mode it additionally allows for a cooling down of the heat left in the device.
