A heat regenerative adsorption refrigerator using spiral plate heat exchangers as adsorbers and an adsorption heat Dump for air conditioning using plate fin heat exchangers or plate fin shell and tube type 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 kinds of adsorption systems. With a heat source temperature of 100 degrees C, the refrigerator achieved a refrigeration power density of more than 2.6 kg ice per day per kg activated carbon with a coefficient of performance (COP) of 0.13, and the heat pump achieved 150 W/kg activated carbon for air conditioning with a COP of about 0.4.
