That is one very nice advantage of the English system when working with refrigeration equipment. In Metric, you have kw for shaft power from a motor, kw for electricity, and kw for heat. Gets kind of confusing.

Thanks for the compliment humid. No need to feel inferior. I have put up my share here of what are probably viewed as dumb questions. I only halfway get enthalpy anyway.
But I gotta warn you, it is lame. Don't hold it against me. I spend too much time at hvac-talk.com.
I have a pro working on the site though, should come out pretty nice. I plan on putting up a tech info section, like a library of technical brain droppings from the last 5 years of doing this.
