Jeff - elaborate on this parallel arraingement.
I am learning a LOT. Keep up the excellent discussion. For example, I had not completely thought out the trade off with larger heat exchangers (more efficient) with losses with turn off and turn on.
If the system is on almost all the time, then the transient inefficiency at turn on and off is minimized, but that means a tough sizing.
If the COP for this NZ system is 4+ then the EER will be spectacular. Knowing the specific area, they have little to no AC load. If you EVER have the chance, you MUST visit NZ. A simply incredible, friendly and beautiful country. Damn if it is a 17 hour flight from the USA to there . . . .
Great discussions between you two!
Steve
