Abstract
A method of operating an air conditioning system includes changing output of the compressor based on a temperature limit of the evaporator. The temperature limit is one of a predetermined fixed temperature limit and a variable temperature limit. The method also includes determining the variable temperature limit by determining a target air outlet temperature for conditioned air in a control space, detecting an actual evaporator temperature, calculating a difference between the target air outlet temperature and the actual evaporator temperature, finding a predetermined first temperature adjustment that correlates to the difference, finding a predetermined second temperature adjustment that correlates to another condition, and calculating the variable temperature limit by adjusting the fixed temperature limit by one of the first and second temperature adjustments.
