How is solar energy cooled?

Since solar energy is an energy source, it should be able to do all kinds of work. Similar to the refrigeration principle of refrigerator, solar energy can also be used for refrigeration, except that the working medium used in solar refrigeration equipment is ammonia water or lithium bromide instead of Freon. Its structure generally consists of six parts: collector-ammonia generator, heat exchanger, condenser, refrigeration evaporator, absorber and ammonia circulating pump. The Air Conditioning Institute of China Research Institute of Building Science and Beijing No.3 Cotton Textile Factory once conducted an experiment: a room with a height of 4. 1 m and a collector area of 40 square meters was cooled by absorption with ammonia water, and the cooling capacity could reach 7000 kcal/h (4. 1868×7000 kj/h), and the effect was satisfactory.

Using this principle, various solar ice makers have been manufactured. In this way, the saying "let the sun bask in popsicles" is not a joke, but a living fact.
