Experimental study on dynamic performance analysis of a flat-plate solar solid-adsorption refrigeration for ice maker

摘要

A flat-plate solid-adsorption refrigeration ice maker has been built for demonstration pur- poses. The working pair consists of methanol used as the refrigerant and activated carbon as the adsorption medium. The adsorbent bed ins constructed of two flat-plate collectors, with a total surface area of 1.5 m~2. Solar radiation can be simulated with quartz lamps and some important parameters such as temperature and pressure of each subsystem can be handled by a computer. The experimental results show that this machine can produce 4-5 kg of ice after receiving 14-16 MJ of radiation energy with a surface area of 0.75 m~2, while producing 7- 10kg of ice after receiving 28-30 MJ of radiation energy with 1.5 m~2.
