Abstract
An air conditioning apparatus having a dehumidifying mode so that the apparatus is able to cool and dehumidify air in a space to be conditioned and also dehumidify air in the space with no sensible cooling of the air. The apparatus has both an evaporator and a heater. A solenoid operated stop valve allows hot refrigerant to flow through the heater when the valve is open. In its cooling mode, the apparatus operates much as a conventional vapor compression air conditioner, with the stop valve shut and no refrigerant flow through the heater. The stop valve opens to align the apparatus for its dehumidifying mode. In that mode, a portion of the hot refrigerant exiting the compressor discharge bypasses the outside condenser and flows through the inside heater. In the dehumidifying mode, air heated by passing over the heater is mixed with air cooled and dehumidified by passing over the evaporator at the air outlet of the air conditioner to produce a stream of dehumidified air at the approximate temperature of the inlet air. The invention is particularly suited to room air conditioner applications but may be used in other types of air conditioning systems.
