A heat-regenerative adsorption refrigerator using spiral plate heat exchangers as adsorbers and an adsorption heat pump for air conditioning using plate fin heat exchangers as adsorbers have been developed and researched, experimental research results are shown. The activated carbon-methanol adsorption pair is used for the two adsorption systems, which yield a refrigeration power density of more than 2.6 kg ice per day per kg activated carbon and 150 W kg(-1) activated carbon for air conditioning, respectively.
