摘要
Systems and methods to control an electronic expansion valve (EEV) of a vapor compression system are described. A heating ventilation, and air conditioning (HVAC) system includes control circuitry having a sensor. The control circuitry sets a control setpoint of a vapor compression system such that an electronic expansion valve operates across a first operating range. The control circuitry receives a signal from the sensor indicative of an operating condition of the vapor compression system. The control circuitry adjusts the control setpoint based at least in part on the operating condition. The control circuitry controls operation of the electronic expansion valve based at least in part on the adjusted control setpoint, wherein the electronic expansion valve operates across a second operating range, different from the first operating range, at the adjusted control setpoint.
