Abstract
A refrigeration system control method and apparatus for minimizing off cycle losses during a cooling mode of operation 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 valve in the refrigerant line and a compressor apparatus connecting the other end of the indoor coil to the other end of the outdoor coil includes the steps of sensing the humidity of an indoor space to be cooled by the refrigeration system to determine whether the sensed humidity is below a preset humidity setpoint level or above the preset humidity level, and controlling an energization of an indoor coil fan during a time period starting with an energization of the compressor apparatus and ending after the deenergization of the compressor apparatus and having a fan energization duration during the time period dependent on the sensed humidity.
