I have a friend who is an ME with Trane (a big manufacturer of both air conditioners and compressors). I'm going to see if maybe he can answer some of the questions posed in this thread.

Thank you Jerry and Bill for taking the time to look into this problem of mine more deeply.
Unfortunately, even as I read through your thoughtful replies, the problem is not resolved. A BTU/hr. is a unit of Power, as are HP and Tons Refrigeration. And with airconditoners, the rated BTU/hr of cooling capacity is much *greater* than the rated BTU/hr of energy input. You can leave HP out of it and just use the watts rating for energy input and the BTU/hr rating for cooling capacity.
For example a 610 watt air conditioner is rated for 6000 BTU/hr cooling capacity. 610 watts=2077 BTU/hr yields 6000 BTU/hr cooling capacity. Does this not seem odd?
There is something I am obviously missing here, but I'll be darned if I can figure it out, so far. I'm checking this further. I'll let you know what I find out.
