초록 ▼

An air conditioning apparatus having a dehumidifying mode so that the apparatus is able both to cool and dehumidify air in a space to be conditioned and also to dehumidify air in the space with no sensible cooling of the air. The apparatus has two heat exchangers in its indoor section and two heat exchangers in its outdoor section. In its cooling mode, the apparatus operates much as a conventional vapor compression air conditioner, with both outside heat exchangers operating in series as a single evaporator. A four way reversing valve shifts to align the apparatus for its dehumidifying mode. In that mode, hot refrigerant is directed to one of the inside heat exchangers before reaching one of the outside heat exchangers that continues to function as a condenser. The cooled refrigerant bypasses the second outside heat exchanger before passing through the second inside heat exchanger that continues to function as a evaporator. Air to be conditioned flows through the indoor section so that, in the dehumidiying mode, air heated by passing over the one inside heat exchanger is mixed with air cooled and dehumidified by passing over the second inside heat exchanger 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.

대표청구항 ▼

A vapor compressing air conditioning apparatus, having at least air cooling and air dehumidification operating modes, comprising: a first closed refrigerant flow loop from compressor means to a first condensing heat exchanger means to second condensing heat exchanger means to first throttling means to dual function heat exchanger means to evaporating heat exchanger means to said compressor means; a second closed refrigerant flow loop from said compressor means to said dual function heat exchanger means to said second condensing heat exchanger means to second throttling means to said evaporating heat exchanger means to said compressor means; and flow control means for causing refrigerant to flow through said first closed refrigerant flow loop when said apparatus is in its cooling operating mode and through said second refrigerant flow loop when said apparatus is in its dehumidifying mode.
