Chillers commonly known as freezers, 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. Chillers include four main components: compressors, evaporators, condensers, expansion valves, thus achieving the unit refrigeration heating 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.
The chiller is used in air conditioning
A: Industrial chillers - features
Industrial chillers are designed for non-aluminum wave soldering, reflow and other equipment cooling process design, according to temperature control temperature division specifications are as follows: 10 degrees above, 5-10 degrees, 0-5 degrees, -5-15 degrees.
Two: central air conditioning - features
Water cooler air conditioner is a new type of central air conditioning unit, which concentrates the essence of domestic and foreign products, the use of modern advanced technology manufacturing, high quality, beautiful appearance, the product a total of two categories, (direct blow and duct) Specifications, the cooling capacity from (25000W-199400W). Can be widely used in electronics, food, cinemas, restaurants and other industrial and comfortable places.
Central air conditioning host:
1. Water-cooled chiller with horizontal shell and tube condenser and shell and tube evaporator, which has a simple structure, heat stability, long-lasting efficiency, easy maintenance features, has been recognized as the central air conditioning host the most ideal structure composition.
2. Unit control system using imported plc controller, man-machine interface configuration large-screen touch screen, the interface is simple and generous, intuitive and easy operation.
3. The unit has a reliable safety protection device, including high and low voltage protection, exhaust overheating protection, compressor motor overheating protection, overload current protection, antifreeze temperature protection, water protection device emergency stop switch, Melting bolt, valve and so on.
