ABSTRACT:
A refrigerant system adjusts, in a coordinated prioritized manner, the variable capacities of a compressor, evaporator fan and a condenser fan to minimize the system's overall power consumption while maintaining a comfort zone within a target comfort range. The target comfort range is defined by desired temperature and humidity limits. When the comfort zone is within the target comfort range, the system periodically attempts to reduce the compressor capacity. If the attempt succeeds, the evaporator fan capacity is then minimized. The condenser fan capacity can also be minimized provided the refrigerant system can maintain at least a minimum saturated suction temperature of the refrigerant flowing from the condenser to the compressor.
