AIR CONDITIONING METHOD USING LIQUID DESICCANT

摘要

The present invention relates to a Process for Energy Efficient Conditioning of Air Using Liquid Desiccant (CAULD) with the contacting device functioning as adiabatic/diabatic humidifiers/dehumidifiers and/or direct/indirect Evaporative Coolers (EC) wherein the LD is regenerated by multi stage or single stage regeneration while ensuring the outgoing air stream free of LD. The main advantages of the CAULD is that the outgoing air stream is free of desiccant as compared to the conventional LD based air conditioning, use of low grade heat sources and possibility of recovering water. This is possible by the appropriate design of the dehumidifier, regenerator, liquid-liquid heat exchanger air-air heat exchangers and other components of CAULD. Significant reduction in weight and cost can be achieved with the use of alternate materials such as plastics and this eliminates problems due to corrosion. The system is compact, low weight and techno-economically viable for air-conditioning.
