Good morning everyone!
Well, I'm getting ready to replace the compressor in my heat pump at home. According to the Copeland Performance Sheets, it's drawing too much current.
So, I'm thinking to myself, must be something wrong inside.
ZR34K1PFV (obsolete compressor)
It's drawn too much current from day one, and checked everything out, it's okay. Ohm value from winding to winding, capacitor okay. It does not over heat, or anything. So, I just purchased a clamp on watt meter. Verified it's wattage, and the wattage is dead on as compared to the performance sheet for the conditions is operating. I'm having a little problem understanding just why.
Conditions: 60 psig suction 162 psig discharge. 60hz
Volts 240v
Wattage on Run winding to line: 1.15KW
Wattage on Common to line: 1.98 kw
Wattage on Start winding to capacitor: .90kw
Performance sheet said (at closest condition) 1960 watts. Why the difference between Run and Common?
Here's the other kicker: Amp draw 12 amps. Performance sheet is 9.5 under those conditions.
