Will a VFD work on a standard heat pump compressor without damaging the compressor or other components?
This will be used only for the compressor, not any other controls, like reversing valves, fans, etc. although a fan is possible at a future date.
I am considering implementing a VFD and a 3mode (PID) controller (instead of the thermostat) for varying the speed according to demand. I know they make VFD drives for the newer heat pumps but I do not know the extent of the associated changes.
I have a used compressor that can be used as a test but I would like some advice before I start.
Any advice or help on this from an expert will be sincerely appreciated.
Thanks in advance for your time and efforts on this.
