摘要
An energy-efficient air conditioning control method regulates the capacity of a variable capacity refrigerant compressor (12) based on the compressor suction and discharge pressures and a measure of the ambient temperature. A target suction pressure is selected based on the ambient temperature and the sensed discharge pressure, and the capacity of the compressor (12) is adjusted as required to attain the target suction pressure. In a first embodiment of the control method, the ambient temperature is used to select a target evaporator outlet air temperature, which is used along with the sensed discharge pressure to select the target suction pressure, while in a second embodiment of the control method, the target suction pressure is selected directly on the basis of the ambient temperature and the sensed discharge pressure.
