Cooling history of the world

Closed-type refrigerators, in order to improve competitiveness 3. Currently, ammonia and lithium bromide water of a group of water = only for absorption refrigeration system. In 1938, the United States Zellhoeler company, Copley company and the company has used over Marval F and J Ang l2 and triethyl glycol dimethyl since World War II, it is main solvent for freon 22: Try to oil , acetate and more complex organic matter units (amine, ammonia material, ethylene glycol, etc.). Since 1957, U. of Rome Selledo President, the United States B. T. Mr. Eiseman, Mastrange] o person, Mr. and the Soviet Union to continue to do a lot of work. 4. Since the implementation of energy savings that people pay more attention to since the absorption chiller is once taken seriously, because the refrigerator can make use of waste heat. Since 1970, the Soviet Union and the United States were studied. It advocated the use of waste heat in the summer heat and power plant, with production of cold-water absorption chiller. Use of solar absorption chillers can also find a new way. In the refrigeration field, hire the current state of technology, people advocated the use of solar energy for air conditioning, the most applicable or absorption chiller. In 1950 or so, in many countries have achieved only a small solar operated absorption chiller. Around 1965, people began to seriously study the solar air blame, and the first University of Queensland in Australia have been successful, and then from 1970 onwards. The stomach is also a lot of U.S. schools, laboratories, and has installed more residential solar energy air-conditioning devices. 1976, the United States total about s1) o sets of absorption of solar air conditioning units, almost all using lithium bromide. Generator has the heating of the year is 75-8 ● sun small boat. Stage in the absence of sunlight, the means of electricity or fuel oil heating. In addition to right foot traditional-style loop closure creeping absorption system, the 1940 has designed a lithium bromide with water,[link widoczny dla zalogowanych], the opening match warm-income systems. But is seldom used. (Continued) ...
