Abstract
An air conditioner unit includes a refrigeration loop including an indoor heat exchanger and an outdoor heat exchanger, a compressor for circulating refrigerant, and an electronic expansion valve. A controller receives a command to perform an operating cycle at a target compressor speed, determines a starting position of the electronic expansion valve using a valve position equation that is a function of the target compressor speed, an indoor temperature, an outdoor temperature, and empirically determined constants, and initializes the operating cycle with the electronic expansion valve at the starting position.
