What Is an Absorption Chiller?
Refrigerators that rely on the role of the absorber-generator set to complete the refrigeration cycle. It uses a binary solution as a working medium, in which a low boiling point component is used as a refrigerant, that is, using its evaporation to cool; a high boiling point component is used as an absorbent, that is, using its absorption of refrigerant vapor to complete the working cycle . Absorption refrigerators are mainly composed of several heat exchangers. Commonly used absorption refrigerators are ammonia water absorption refrigerators and lithium bromide absorption refrigerators.

- Ammonia absorption refrigerator
- Aqueous ammonia solution is used as the working medium, where ammonia is used as the refrigerant and water is used as the refrigerant
- Carrier's invention of lithium bromide absorption refrigeration technology in the 1950s did not immediately promote it. (At that time, electricity and energy in the United States were not in short supply. The global concern about Freon refrigerants damaging the ozone layer of the earth s atmosphere did not attract enough attention.) research Development. Japanese manufacturers have vigorously developed since the introduction of lithium bromide technology. Companies such as EBARA, Hitachi, Mitsubishi Heavy Industries, and Kawasaki Heavy Industries have formed mature and stable technologies. At present, domestic domestic lithium bromide units account for about 90% of the host market.
- In 1982 (perhaps 1981) Carrier, the inventor of lithium bromide unit technology, in turn purchased lithium bromide technology from Ebara! American companies including York and Trane have also purchased lithium bromide unit technology from Japanese manufacturers.
- Mr. Akira Takada, the chief engineer of Ebara, published the book "Absorption Refrigerator" in 1982, which was translated into various languages by various countries, leading the development of the world's absorption air-conditioning industry.
- Domestic ammonia water absorption absorption refrigerators have also come out, and large ammonia water absorption refrigeration devices have also been applied in the chemical industry. Domestic research institutions in universities have begun research in this area. Shandong Taishan Group's 1-100 million kcal unit has also been promoted and used in various industries. With the gradual depletion of chemical energy, ammonia water absorption refrigeration equipment driven by waste heat will contribute to domestic energy conservation and emission reduction. [1]
