#1 is great idea if you need to replace a failed compressor. Big side benefit besides higher COP is that in HP mode the evaporator does not freeze up. Did this for own house. #4 Beats even #1 if you have a 3 phase compressor - I replaced my failed compressor with a single phase compressor as that was what I had on hand, would have used the VFD approach with a 3 phase compressor if I'da had one on hand or could have found one at a low price. BTW - I would try to find the cheapest CHINESE VFD that I could <G> |
