Two air conditioning compressors connected in parallel supply an evaporator suitably valved for operation at full capacity with both compressors for maximum normal comfort cooling, for operation at half capacity with one of the compressors for half capacity normal comfort cooling, and for operation at three-quarter capacity with both compressors for maximum dehumidification of the treated air without frosting the evaporator. Waste heat from a refrigerant compressor may be used to reheat the air during the dehumidification operation.

An air conditioning and dehumidification system comprising: (a) means for compressing refrigerant and selectively operable at generally full and reduced capacities; (b) means for evaporating refrigerant and having means for selectively operating at generally full and reduced capacities; (c) means for directing compressed refrigerant from said compressing means to said evaporating means for evaporation therein; and (d) means for controlling said compressing meand and said means for selectively operating said evaporating means selectively responsive to the temperature and moisture content of air ambient to said evaporating means for selectively: (aa) operating said compressing means at full capacity and said evaporating means at full capacity for substantially maximum comfort cooling without substantial dehumidifying of said ambient air, (bb) operating said compressing means at a reduced capacity and said evaporating means at a corresponding reduced capacity for corresponding reduced comfort cooling of said ambient air, and (cc) operating said compressing means at full capacity and said evaporating means at a reduced capacity for substantially maximum dehumidifying of said ambient air without substantial frosting of said evaporating means.
