Absorption refrigerators

Absorption principle

— absorption refrigerators are known as devices that can operate not only from electricity, but also from a gas cylinder. The principle of their operation is based on the absorption of ammonia by water and the heating of the water-ammonia solution with a heater; the heater can be either electric or gas. Accordingly, one of the main advantages of such models is independence from electricity. This is especially true when used outdoors, especially since the gas consumption is very low — for example, a 5-liter cylinder can last for almost 10 days of continuous operation. At the same time, in terms of speed and overall cooling efficiency, such models are noticeably superior to thermoelectric ones, although they are inferior to compressor ones. On the other hand, the design of the absorption car refrigerator is quite simple, and the noise level is low. The volume of such units can be quite impressive — up to 100 liters or more.
