Development of no valve solar ice maker

A no valve, flat plate solar ice maker is developed on the basis of previous research achievements of a large number experiments and theory analysis. There are no valves and measure gauges installed on this advanced device, also no moving parts on this device, activated carbon and methanol is used as working pairs for this no valve solar ice maker. Experimental results under both indoor and outdoor showed that each subsystem, such as adsorbent bed, condenser, evaporator, demonstrated a good performance on system running processes; this no valve solar ice maker prototype is approached to practical application of mass production from view of cost and techniques. After the successful study of this no valve solar ice maker, two new improved economic solar ice makers are fabricated for mass application in China now. All this will accelerate practical application of solid adsorption refrigeration driven by solar energy.
