    摘要: A controller includes a first input that receives a signal indicating an energy consumption value of a compressor, a second input that receives a signal indicating an energy consumption value of a variable speed condenser fan, a third input that receives a signal indicating an ambient temperature, a fourth input that receives a signal indicating a condenser temperature, an output that provides a control signal to the variable speed condenser fan, a memory that stores a temperature difference set-point, and a processor in communication with the inputs, the output and the memory. The processor calculates a difference between the ambient temperature and the condenser temperature, compares the difference with the temperature difference set-point, controls the variable speed condenser fan based on the comparison, monitors the energy consumption values, and modulates the temperature difference set-point to minimize energy consumption.
