Adsorption Coolers
An adsorption cooler operating in accordance with the periodical adsorption principle and consisting of at least one adsorption container filled with zeolite. At least one condenser with a collecting container for the water which desorbs from the zeolite and an insulated cooling container which may be closed by a shut-off member are serially connected with the adsorption container. In the cooling container, the adsorption cooler generates ice in stages which acts as a cold buffer. The system is usable for example in solar cooling systems, vehicle air conditioning units and air conditioning insulation as well as beverage coolers.
We use helium adsorption coolers for space. Two rocket –borne 3He and 4He coolers and a space borne 3He refrigerator developed to cool bolometric detectors have been successfully flown.
