Industrial cooling water circulating cold water system which as the name implies: industrial cold water machine, industrial ice machines, industrial cold water systems, industrial chillers, industrial chillers, because this device is widely used, the reason for their name is different. Industrial cold water system is an industrial equipment section for circulating liquid cooling rapidly to improve production efficiency of cold water facilities. Liquid flows through an evaporator of liquid industrial cold water cooling systems needed to reach the goal. Compressed industrial cooler cycle including compression chillers four main components (compressor, evaporator, condenser, filter drier, thermal expansion valve), which has played a most important part of the process of cold water in the cold water. Use of multiple compressors in parallel, each compressor comes with a separate cold water circuits, namely evaporators, condensers are completely independent; all compressors by unified microcomputer control system, one by one open, shut, never with each other do not interfere with each other, with nine wells brand all imported genuine original production, the single failure rate is very low, the above reasons, you can ensure that the series has a highly stable machine performance, the first choice in many years of continuous operation. Single-stage refrigeration cycle single stage chiller is used widely in the refrigerator for a class, it can be applied aspects of ice, air conditioning, refrigeration and industrial food production processes. Single-stage refrigeration cycle refers to the refrigerant in the cooling system have been compressed, condensation, throttling, four evaporation process, will complete the single stage chiller cycle, which reached a refrigeration purposes. Refrigeration system evaporator, single-stage compressor, oil separator, condenser, ammonia storage device, the ammonia liquid separator, throttle and other ancillary equipment, etc., with each other through a pipe coupled in the closed system. Wherein, the evaporator cooling capacity is a conveying device, the heat absorbed by the cooling body refrigeration liquid refrigerant after evaporation; compressor is the heart of the system, plays a suction, compression, transport refrigerant vapor action; oil separator for sedimentation compressed refrigerant vapor separated in the oil; condenser compressor discharge temperature of the refrigerant vapor is condensed into a saturated liquid; ammonia storage device for storing the refrigerant condensed in the condenser ammonia solution, adjusted between the condenser and the evaporator supply and demand of the refrigerant liquid ammonia; ammonia liquid separator systems for liquid ammonia gravity important ancillary equipment; throttle the refrigerant from the throttling effect while controlling and regulating the flow of refrigerant into the evaporator liquid and the system is divided into high side and low side of the two-part two-stage refrigeration cycle system, dual-stage refrigeration cycle is developed on the basis of a single-stage refrigeration cycle, the compression process is divided into two phases, the refrigerant vapor from the evaporator first into the low to mid-level cylinder compression pressure, through the middle of the cylinder to cool down before entering the high pressure stage, compressed to the condensing pressure into the condenser. General evaporation temperature at -25 ℃ ~ -50 ℃, should adopt a two-stage compressor refrigeration. Refrigeration system evaporator, two-stage compressor, an oil separator, a condenser, an intercooler, ammonia storage device, the ammonia liquid separator, throttle and other ancillary equipment, etc., with each other through a pipe coupled in the closed system . Among them, the use of a small amount of liquid intercooler refrigerant absorbs heat of vaporization at the intermediate pressure, superheated steam discharged from the low pressure stage is cooled to reduce the high pressure stage of the suction temperature, but also the high-pressure liquid refrigerant is cooled. Compressor refrigeration system basically consists of: compressor refrigeration system is the whole core component refrigerant is compressed source of power. Its role is to input electrical energy into mechanical energy, the compressed refrigerant cycle. Evaporator: The evaporator is relying evaporator refrigerant liquid (actually boiling) to be absorbed by the cooling medium heat exchanger member. It functions in a refrigeration system is to absorb heat (or cold output). In order to ensure the evaporation process can be long-lasting and stable, we must continue with the refrigeration compressor pumped the gas evaporation, evaporation to maintain a certain pressure. Condenser: a condenser in the refrigeration process and play the output of heat to the refrigerant condensed effect. After the refrigerant discharged from the compressor high pressure superheated vapor into the condenser, which in all of the heat absorbed by the working process, including the refrigerant compressor and the evaporator and heat is absorbed in the pipe are transmitted to the surrounding medium by the cooling water or fans away; refrigerant high pressure superheated steam condenses back into a liquid. (Depending on the cooling medium and the cooling mode, the condenser can be divided into three categories: shell and tube condenser, finned condenser, evaporator and condenser.) Thermal expansion valve: thermal expansion valve flow both in the refrigeration system valve, and refrigeration equipment throttle, which is installed between the filter drier and evaporator refrigeration equipment, its temperature package is wrapped in the outlet of the evaporator. Its main role is to make high-pressure refrigerant liquid at room temperature, throttle down when passing through the thermal expansion valve, into a low-pressure refrigerant wet steam (mostly liquid, a small part of the steam) into the evaporator, vaporized in the evaporator endotherm, while the cold water to achieve the purpose of cooling. Dry filter: In the refrigeration cycle must prevent moisture and dirt (oil, iron, copper scrap) from entering, the main source of water is the newly added trace moisture refrigerant and oil contained in the system or due to maintenance When the air is brought into the water. If the system does not preclude clean water, when the refrigerant throttle (thermostatic expansion valve or capillary) through, because sometimes downward pressure and temperature of water will solidify into ice, making obstruction, affecting the normal operation of the refrigeration unit. Therefore, in the refrigeration system must be installed in dry filter. Reservoir: accumulator installed after the condenser, the condenser and the outlet tube is in direct communication. Refrigerant liquid flows into the condenser should be unimpeded within the reservoir, so that you can take full advantage of the condenser cooling area. On the other hand, when the heat load changes of the evaporator, the refrigerant liquid required amount also changes, then, the reservoir will act as adjustment and storage of the refrigerant. Cold water system for small devices often do not install the reservoir, but the use of the condenser to adjust and store refrigerant. Refrigerant: Most industrial cold water systems used in modern industry are used as a refrigerant R22 or R12. The refrigerant is cold refrigerant flow system, its main role is to carry heat, and realize endothermic and exothermic changes in the state.
