Abstract
A desiccant assisted air conditioning system, incorporating desiccant members in each of separate passages for process air and regeneration air, is presented to significantly improve the cooling efficiency to utilize the low and high temperature heat sources of a heat pump device. While one desiccant is dehumidifying so that moisture in the process air is being adsorbed in the one passage while the regeneration air is removing moisture from the desiccant in the other passage. The combined effect of this arrangement enables to produce cooling effect in excess of the cooling capacity of the heat pump device, and to achieve a significantly higher energy efficiency for operating the air conditioning system.
Claims6
A desiccant assisted air conditioning system comprising:
- a process air passage for dehumidification of process air and a regeneration air passage for regeneration of a desiccant material;
- at least two desiccant members, one desiccant member being disposed in said process air passage and other desiccant member being disposed in said regeneration air passage;
- a sensible heat exchanger;
- and a heat pump device,
- wherein a high temperature heat source of said heat pump device is disposed in said regeneration air passage for heating regeneration air, a low temperature heat source is disposed in said process air passage for cooling of process air, and said sensible heat exchanger exchanges heat between process air which has passed through said one desiccant member and regeneration air which has not yet entered into said other desiccant member.
