There are a few ways to approach this one.

First choice: Mad Max bartertown rube Goldberg contraption. Everything is independent of everything else and is simple as it can be. Cheaper but not so efficient or reliable.

Second choice: big single speed compressor and duty cycle control. Larger heat exchangers equate to longer cycles and higher efficiency. Price depends on what you can scrounge up.

Third choice: variable speed digital control and equipment. Efficiency, price, and reliability all depend on homework done up front and thorough testing and trials. Not usually cheap but more set it and forget it.
