✦ Synopsis

This paper presents the description and operation of a solar-powered ice-maker with the solid adsorption pair of activated carbon and methanol. A domestic type of charcoal was chosen as the adsorbent, and a simple flat-plate collector with an exposed area of 0.92 m was employed to produce ice of about 4-5 kg d\ at an evaporator temperature of about !6°C. The above system could achieve solar refrigeration COP of about 0)1-0)12. With the description of the idealized refrigerating system, the influences of evaporating temperature, adsorbing temperature and condensing temperature on the COP were also analysed.
