Abstract

See full text

A specially designed electronic expansion valve control system is provided for use with a refrigerant-based air conditioning circuit having a compressor, a condenser coil, an electronic expansion valve and an evaporator coil fluid coupled in series. The control system includes a unit control and an expansion valve control. The unit control is operative to receive compressor operation-related signal information and responsively generate at least one output signal representative of the received compressor operation-related signal information. The expansion valve control is operative to receive from the unit control only the at least one output signal, and to receive from one of the coils coil operation-related signal information, and to responsively output a control useable to control the expansion valve, the control signal being related in a predetermined manner to the signals received by the expansion valve control.
