I would like to know why the HVAC industry design practice for at least the smaller systems that I know of still seems disadvantaged from an electrical efficiency viewpoint. I am certainly NOT a professional in this area but rather a retired electrical engineer with a fair amount of hands on experience with smaller A/C systems. Why are the compressors still "canned" forcing all the motor heat into the refrigerant and then using fan energy to remove that heat. Why not use mechanical seal compressors as the automotive HVAC industry traditionally still does quite reliably. Similarly, why is the air handling fan motor always placed in the conditioned air space adding that much additional heat load to the system?If you would like to email me directly, please decipher my email from: ralft(at)hal- pc(dot)org
