A control methodology for dynamically adjusting the switching limits of a cycled refrigerant compressor in an air conditioning system with the objective of achieving an optimal or specified tradeoff between compressor cycling frequency and discharge air temperature variation under all operating conditions. In a first embodiment, the compressor cycling limits are controlled to maintain a virtually constant discharge air temperature variation for all operating conditions. In a second embodiment, the compressor cycling limits are controlled so that the discharge air temperature variation changes in relation to the discharge air temperature to provide a virtually constant human comfort level for the occupants. And in a third embodiment, the compressor cycling limits are controlled so that the discharge air temperature variation changes in relation to the ambient or outside air temperature to provide a virtually constant human comfort level for the occupants.
A method of operation for an air conditioning system including an evaporator for conditioning inlet air, a refrigerant compressor that is cycled on and off to control a cooling capacity of the evaporator, and a heater core configured to re-heat a selected portion of the conditioned inlet air to affect a discharge air temperature of the system, the method comprising the steps of:
