Industrial chiller refrigeration equipment refers to the equipment mainly used for crew food refrigeration, all kinds of goods refrigeration and cabin air conditioning in summer days. It is mainly composed of compressor, expansion valve, evaporator, condenser, accessories and pipeline. According to the working principle, it can be divided into compression refrigeration equipment, absorption refrigeration equipment, steam jet refrigeration equipment, heat pump refrigeration equipment and electric heating refrigeration equipment. At present, the compression refrigeration equipment is the most widely used on ships. Through the working cycle of the equipment, the heat of the object and its surrounding is removed, resulting in and maintaining a certain low temperature state. The main refrigerants used are freon and ammonia, especially Freon. However, due to the destruction of ozone layer by freon, it has been restricted by environmental protection regulations. Ammonia and other new refrigerants are being re used and trial produced.
Before the development of artificial refrigeration, people have known to use natural ice and snow to maintain low temperature in simple equipment, that is, to use natural cold source. In China, natural ice was used to preserve food about 3000 years ago. Until now, people still use natural cold sources such as ice, snow and groundwater. The cold storage device cooled by natural ice or artificial ice can only reach limited low temperature, and the technical and sanitary conditions are poor, so it is difficult to meet various requirements. Modern refrigeration device is the application of refrigeration machine to cool.
In 1834, the United States successfully manufactured a continuous working refrigerator with ether as working medium. In 1844, the United States trial produced a refrigerator with air as working medium, which was used to make ice and cooling air in hospitals. From 1872 to 1874, with the advanced technology, ammonia compressor was invented and ammonia vapor pressure compressor was made. This is the starting point of modern compression refrigerator. In the 1950s, the French Carles brothers developed absorption chillers and ammonia water absorption chillers with sulfuric acid and water as working medium. In 1910, steam jet refrigerator appeared. Freon refrigerant appeared in 1930, which promoted the rapid development of compression refrigerator. In 1945, the United States developed a silver bromide absorption refrigerator.
