They are based on the air pressure within the tank. They come on then the pressure drops to a pre-set point and shut off the pressure raises to a pre-set point.
pump is used to move liquid from one point to another, while compressor is used to compress and move gases from point to point.

Surge is a point when compressor is not add enough energy to overcome system resistance.
More than likely, your H-A/C control is set to Defrost. In most vehicles, when this is set to Defrost, the A/C Compressor runs continually.More than likely, your H-A/C control is set to Defrost. In most vehicles, when this is set to Defrost, the A/C Compressor runs continually.
Turndown: The allowable operating range for the centrifugal compressor between the design point and the surge line at any given speed for a fixed compressor head.
In a centrifugal compressor, the energy is transferred using a set of impeller blades and balancing drums. These balancing drums can be on the inlet or outlet side of the compressor and help to space out the energy in the compressor.
No, as long as you don't turn the A/C on or set the controls to Defrost which will cause the compressor to run.
The compressor is coming on because you have the heater set to defrost. Take it off defrost and the compressor will not come on. I would suspect the compressor is locked up.
you shouldn't need to unless it set a check engine light for some reason. if it was just a compressor change for, say, the compressor locked up then no. hope this helps.
A pressure switch would activate the compressor's motor starter. When the pressure drops below a set 'low' limit, the motor powering the compressor turns on, when the pressure reaches a set 'upper' limit, the unit turns off...How's that for "Straight Forward"?
Yes your compressor comes when you set your thermostat to "Fan" setting and you have it on cool setting.
