the coil will operate as evaporator and the coil as condenser.
In United States, usually the system will operate in cooling mode and when it's OFF, in heating mode. .
we will want to run our heat pump in heat mode to heat up the room to maintain temperature for the human body..
The valve needs certain head pressure to operate and it will cause the air conditioning system to stop operating.
The solution to this problem is to install fan speed controller that will be able to regulate the speed of the outdoor fan of the condenser.
By changing the voltage to it, In order to use the controller, check the specifications of the fan to ensure that the fan is able to be modulated..
sensor will be mounted on the liquid line of the condenser where its temperature is used to control the speed of the fan.
By regulating the speed, the head pressure will not drop too low hence the heat pump will still be able to operate in cooling mode even.
In cooling mode, the hard start feature will be in which the voltage to the fan will be at its maximum during the first few seconds to ensure rotation of the fan.
