What controls the A/C compressor clutch cycle in a car?

My car only has the fan speed to control the coolness. If the compressor cycle does not change, where the excess high pressure liquid freon go when I turn down the fan speed? That means If I slow down the fan, will the compressor cycle also slow down and save more energy?What controls the A/C compressor clutch cycle in a car?
The Thermostat in the 'a/c', controls the compressors cycle.


If you turn the fan to low, the evaporator coils cool off less, and the compressor will not cycle as often, therefore saving you fuel.


It would work the same as turning the controls to a higher temp setting. The compressor is an ';ON or OFF'; device.

The compressor will continue to run but with a bit less


load, so it would require less power to run. You may not


be able to measure the difference tho. Some cars have


a compressor shut-off that temporarily cuts the clutch


power when in a high load steer (parking) or during


wide-open throttle (passing). Hope that answers your


question.
