Domestic cold water machine has occupied the domestic market
The cold water machine for the main business of brands, four brands such as Carrier, Trane, G, Mike Weil, in addition to York to maintain a certain growth, other brand market share gradually by many domestic brands. In addition to brand awareness, product quality, customer service and price, service and other factors. Many domestic cold water machine brand is technically mature, after sale is also more perfect, coupled with high cost of products, people are more willing to choose domestic brands.
Cold water machine, as in the industry: water cooled and air-cooled chiller chiller is divided into two kinds, low temperature and normal temperature chiller chiller in temperature control, room temperature control in 0 to 35 DEG C range. The temperature of the low temperature machine is controlled in the range of 0 ~ -120. (on the market in addition to the chiller and call out, such as: industrial chiller, freezer, freezer, refrigeration machine, industrial cold water machine, low temperature freezer, screw chiller, screw chiller, water cooled screw chiller, water cooled screw chiller, air-cooled chiller, air-cooled chillers, low temperature brine freezer, brine freezing unit, water cooled screw chiller, water cooled screw chillers, screw chiller, air-cooled screw chiller, air-cooled screw chiller, water cooled screw chiller).
First, the working principle of the cold water machine
Cold water machine is a kind of water cooling equipment, cold water machine is a kind of cooling water equipment that can provide constant temperature, constant current and constant pressure. Its working principle is that the first to machine the inner water tank into a certain amount of water, the water cooling chiller refrigeration system will, then by the water pump cooling water into the cooling equipment, chiller chilled water will heat away after the temperature reached back to the water tank, cooling effect.
Two, the use of cold water machine
Cooling pumps used in industrial applications: chilled water or other liquid are through process or laboratory equipment. Industrial cold water machine is used to control products, mechanisms and plant mechanical cooling of all walks of life. They are usually used for plastic injection molding and blow molding industry, cutting metal processing oil, welding equipment, die-casting and machining, chemical processing, pharmaceutical formulation, food and beverage processing, paper making, cement processing, vacuum system, X ray diffraction, power supply and power station, analysis equipment, semiconductor, compressed air and gas cooling. They are also used for cooling high thermal energy, such as nuclear magnetic resonance imaging and laser specialized engineering projects, and in hospitals, hotels and schools. Industrial applications of the chiller can be concentrated, each unit is cooled to meet a variety of needs, or distributed in each application or device has its own refrigerator. Each method has its advantages. It is also possible that there is a combination of central and decentralized refrigeration machines, especially when the cooling requirements are the same for some applications or the use of integral, but not all.
The use of air conditioning (central air conditioner used in factories, hotels, shopping malls, office buildings and other places) in the air conditioning system, chilled water is usually assigned to the heat exchanger coil, or in air handling units, terminal equipment or other types of cooling in their respective space (S air), and then re circulated cooling water back cooling cooling. These cooling coils transfer sensible heat and latent heat from the air to the chilled water, therefore, the usual desiccant cooling air flow. A typical application of the air conditioning unit rated at 15 to 1500 tons (18000018000000 BTU / h or 53 to 5300 kW) cooling capacity. Chilled water temperature range from 35 to 45 degrees Celsius or 7 ~ 1.5 degrees Celsius, depending on the application needs.
From the point of long-term development, development of domestic cold water machine industry think faster, we must form the core technology and core competitiveness with independent intellectual property rights, in order to realize the breakthrough of the refrigeration industry, occupy the entire domestic market, or even go abroad, to seize the commanding heights of the future competition strategy choice.
