Double-effect adsorption refrigeration device

摘要

The present invention relates to an adsorption chiller using double-effect cycle utilizing middle driving heat source of 100-150 degree centigrade. The cycle consists of two cycles such as high temperature cycle (HTC) and low temperature cycle (LTC). Zeolite-water system and silica gel-water system are used as adsorbent-adsorbate pairs of HTC and LTC respectively. Waste heat of zeolite generated at during adsorption period of the zeolite is re-used for pre-heating and desorbing the silica gel.
