Abstract
A head pressure control system may control a high side operating condition of a vapor compression system. The head pressure control system includes a vapor compression system having a compressor, condenser, expansion valve, and evaporator. The head pressure control system may also include a high side condition sensor, a low side condition sensor, a controller, and a control device. The low side condition sensor may measure and communicate a low side operating condition to the controller. The high side condition sensor may measure and communicate a high side operating condition to the controller. The controller may compare a theoretical high side operating condition to the high side operating condition, and determine a control output. The controller may communicate the control output to a control device, which may influence the high side operating condition based on the control output.
