Chillers commonly known as refrigerators, refrigerators, ice machines, frozen water machines, coolers, etc., because the use of a wide range of industries, so the name also countless. With the continuous development of chillers industry more and more people began to pay attention to the chiller industry, any choice is more and more important for human beings, in the product structure "energy efficiency than water-cooled screw unit", "water source heat pump unit", " Screw-type heat recovery unit "," efficient heat pump unit "," screw-type low-temperature refrigeration unit "and other highly competitive product structure of its nature principle is a multi-functional machine, remove the liquid vapor by compression or heat absorption Type refrigeration cycle. The steam compression chillers consist of four main components of the vapor compression refrigeration cycle compressor, evaporator, condenser, part of the metering device in order to achieve the different refrigerant. The absorption chiller uses water as a refrigerant and relies on a strong affinity between the water and the lithium bromide solution to achieve a cooling effect.
Chillers are generally used in air conditioning units and industrial cooling. In air conditioning systems, chilled water is usually distributed to the heat exchanger or coil in the air handling unit or other types of terminal equipment to cool in their respective spaces, and then the cooling water is redistributed back to the condenser to be cooled. In industrial applications, chilled water or other liquid cooling pumps are through process or laboratory equipment. Industrial chillers are used to control the products, mechanisms and factories of mechanical cooling of all walks of life. Chillers in the form of cooling can be divided into water-cooled and air-cooled, technically, water-cooled than air-cooled energy efficiency ratio of 300 to 500 kcal / h; in the price, the water is much lower than the air-cooled; In the installation, the water cooling to be included in the cooling tower can be used, air cooling is mobile, no other auxiliary.
With the rapid development of economy, the continuous improvement of scientific and technological strength, our chiller manufacturing technology is also changing, and the gap between developed countries is gradually narrowing, but the main core components such as compressors or foreign joint ventures, Inadvertently increased business costs.
Modern society, the application of refrigeration equipment more and more widely, modern refrigeration equipment are used to cool the chiller, chiller market development prospects can be expected. The advanced state of the cold water machine is still some developed countries in the West. Their development trend is also combined with the reality of the country, and vigorously improve the chiller shape, and constantly improve the performance of chillers, chillers to achieve smaller, the effect of increased efficiency. Experts point out that in the increasingly fierce market competition, chillers developed technology matures today, miniaturization, high performance chiller has become a new trend. At the same time, in order to adapt to the rapid development of industrial production, more personalized, more fit production of the actual product will continue to emerge.
