A refrigeration system control for minimizing cycling losses of a refrigeration system having an indoor coil, an indoor coil fan, an outdoor coil, an outdoor coil fan, a refrigerant line between one end of the indoor coil and one end of the outdoor coil, a compressor apparatus and a reversing valve connecting the compressor apparatus between the other end of the indoor coil and the other end of the outdoor coil includes the steps of operating the reversing valve to a state opposite to the one representative of the operating condition of the refrigeration system for a predetermined period of time starting prior to an energization of the compressor apparatus and ending after the energization of the compressor apparatus, restoring the reversing valve to a state needed for the operating condition of the refrigeration system at the end of the period of time while continuing the energization of the compressor apparatus.
A method for controlling a refrigeration system having an indoor coil, an indoor coil fan, an outdoor coil, an outdoor coil fan, a refrigerant line between one end of the indoor coil and one end of the outdoor coil, a compressor means and a reversing valve connecting a compressor means between the other end of the indoor coil and the other end of the outdoor coil including the steps of operating the reversing valve to a state opposite to the one representative of the operating condition of the refrigeration system for a predetermined period of time starting prior to an energization of the compressor means and ending after the energization of the means which period of time is sufficiently short to minimize a differential pressure across the compressor means without allowing a redistribution of a liquid refrigerant in the refrigeration system and restoring the reversing valve to a state needed for the operating condition of the refrigeration system at the end of the period of time while continuing the energization of the compressor means.

A method for controlling a refrigeration system having a compressor means including an inlet port and an outlet port including the steps of selectively introducing a flow path between the outlet port and a low pressure point in the refrigeration system for a predetermined period of time starting prior to an energization of the compressor means and ending after an energization of the compressor means which period of time is sufficiently short to minimize a differential pressure across said compressor means without redistributing a liquid refrigerant in the refrigeration system.
