Morphing Air Conditioner into Autocascade System

[wdrzal]

I reviewed the link for the PGC-150 and it states rated amps 12.5 at 230VAC (2875W). Even with the air-cooled condenser fan, this seem way over 1.5-hp (1.5*750/0.85 = 1324W, the 0.85 is the electric motor efficiency). So it appears to me closer to a 3-hp used by this reciprocating compressor. What am I missing?

A good quality hermetic compressor can be pushed to 200%++ of their rating. They might only last 3 to 5 years (instead of 20+)before the insulation on the windings breaks down. Look @ NEMA motor insulation classes.
