Abstract:
Controls for an air conditioner comprising:a modulated capacity compressor for pumping varying amounts of coolant through a coolant circuit of an air conditioner, modulated return air bypass damper for varying the amount of return air bypassing an evaporator of the air conditioner, a modulated reheater provided adjacent the evaporator for adding reheat to an air stream after the air stream passes through the evaporator, a controller attached to and controlling modulation of the compressor, said controller attached to and controlling the return air bypass damper, and said controller attached to and controlling modulation of a valve that modulates the reheater, said controller attached to and receiving information from a temperature sensor that senses air temperature of conditioned space air produced by the air conditioner, said controller controlling modulation of the compressor to maintain a desired temperature in the conditioned space air, and said controller attached to and receiving information from a humidity sensor that senses air humidity of conditioned space air produced by the air conditioner, and said controller first modulating the return air bypass damper to maintain a desired humidity in the conditioned space air and then said controller second also modulating the reheat valve to control flow of hot coolant gas to the reheater to maintain the desired humidity in the conditioned space air.
