<p>An air conditioning system (100) cools air in an enclosure (110), such as a building. A cooling fluid is supplied by a compressor (120) to a coil (130) in a duct (106). A fan (102) forces air through the duct and is cooled by the coil to cool the enclosure. A logic module (154) drives a motor control subsystem (156) to: deactivate a motor (124) of the compressor, when a monitoring module (150) detects thermodynamic saturation of the cooled air 132 leaving the duct; maintain operation of the fan, until a target temperature in the enclosure has been reached; activate the motor when the monitoring module detects that the cooled air leaving the duct is no longer thermodynamically saturated and a time threshold has been exceeded since deactivation of the motor. The voltage applied to the motor is regulated to be the minimum voltage that allows enough current to flow to provide synchronous rotation of the motor.</p> |
