a fuel burner uses the drive belt from the crank to turn the a/c compressor at all times a/c is requested..........what system does the prius use to run a compressor at all times since the gas side shuts off so often?.....TIA, bill
Battery.

hmmm....typing the word "battery" says little about the process of refrigeration..........thanks for the reply, i guess...........

The same system that your house uses.
Electricity.
The battery drives the AC system. If the battery gets low, the engine does whatever it needs to do at the time to charge the battery up so that it can continue to run the AC system.
Huh?
The refrigeration process is exactly the same--whether it's a Prius, a Buick, your home AC, or a refrigerator.
An electric motor turns the AC compressor. The battery runs the electric motor.
So, what system does the Prius use to run a compressor at all times? One word: battery.
Almost. That Buick (and all conventional cars) uses the engine - not an electric motor - to power the compressor.
The Prius compressor is motor-driven, but is that motor powered by 12V? Traction battery dc? Inverter output ac? Because it dissipates considerable power, it would be more efficient to run it from HIGH voltage, and probably ac after the inverter.

I just realized -- even a high efficiency compressor (vane, scroll) would require at least a 500W motor, so at 12V that would take more than 40 amps. It has to be high voltage.
This can be useful:
An electric motor, drawing power from the traction battery. The 12V system is much too weak to power an A/C system for any length of time. If the A/C draws down the traction battery, eventually the engine will be started up to recharge the traction battery and provide power to the A/C motor.
