Advanced manufacturing industry is an important way for the transformation and upgrading of manufacturing industry in our country and will become the forerunner of our country's participation in international competition.At present, our country profoundly recognizes that the task of manufacturing industry development is urgent. The "13th Five-Year Plan" and "Made in China 2025" Industry development has become a hot spot of concern for all people.Therefore, China's food, medicine, materials, instrument Manufacturing and other industries usher in rapid development.As one of the common laboratory equipment, refrigeration equipment has become increasingly prominent demand.
Refrigeration equipment is a combination of a refrigerator and a facility that uses cold, and different refrigeration methods use different equipment. At present, the most widely used is the vapor compression refrigeration, the main equipment is a compressor (see fluid transport machinery), condensation Valves, evaporators and throttles.
Before the artificial refrigeration began to develop, humans already knew that the use of natural ice and snow in the simple equipment to maintain low temperature conditions, the use of natural cold source. In 1834, the United States J. Perkins trial successful human turn with ether as working fluid can Continuous working refrigerators. From 1872 to 1874, D. Bell and C. von Linde invented ammonia compressors in the United States and Germany, respectively, and made ammonia vapor compression refrigerators, which are modern compression refrigerators The beginning of the 1850s, the French Carlyle brothers have successfully developed with sulfuric acid and water as the absorption of the absorption chiller and ammonia absorption chiller 1910 steam jet-type chiller appeared in 1930 there Freon refrigeration Agent, and promoted the rapid development of compression refrigerating machine.In 1945, the United States successfully developed silver bromide absorption chiller.At the same time, refrigeration equipment technology continues to improve, the industry is also more widely used.
At present, with the rapid development of food, medicine and other industries in our country, the demand for refrigeration equipment as an essential laboratory instrument is constantly increasing, including freezers, chromatography freezers, ice makers, freeze dryers, freeze dryers, chillers , Cryogenic thermostats and other refrigeration equipment have been widely distributed in major laboratories, plastics industry, electronics industry, electroplating industry, machinery industry, construction industry, vacuum coating, food industry, pharmaceutical industry and other manufacturing enterprises to meet the refrigeration needs of various industries.
As a refrigeration equipment, the cooling method of such instruments are mainly direct cooling and indirect cooling two direct cooling with cooling speed, heat transfer temperature difference is small, the system is relatively simple advantages, which are widely used in accordance with the purpose of cooling and utilization of cold Different ways, the refrigeration unit can be divided into refrigeration refrigeration unit, test refrigeration unit, production refrigeration unit and air conditioning refrigeration unit.
At present, in the refrigeration equipment industry in our country, some outstanding instrument industries have keen market perspectives and deep plowing in the refrigeration industry, making important contributions to the development of the manufacturing industry in our country, such as the excellent Leibo Technology (Beijing) Co., Ltd., Equipment Co., Ltd., Shanghai Extension Refrigeration Equipment Co., Ltd., Bosheng Refrigeration Equipment Co., Ltd., and constantly improve the refrigeration equipment technology, speed up equipment Innovation and upgrading to help users solve the cooling problem, which has gradually won the recognition of users in the country to actively encourage the development of the manufacturing sector, the refrigeration sector usher in a new round of business opportunities, domestic refrigeration companies need to seize the opportunity to borrow Potential and.
