Refrigerators, chillers, chillers, chillers, chillers, chillers, water chillers, etc., are numerous because of their extensive use in various industries. The principle of nature is a multifunctional machine that removes liquid vapour from the condensed or thermal absorbent refrigeration cycle. The vapour compressor cold water unit consists of a steam compressor cycle compressor, evaporationer, condenser, and partial measuring devices, thus achieving different refrigerants. Absorption chillers use water as a refrigerant and rely on water and lithium bromine solutions between them to achieve a high degree of irritation。
Refrigerators are refrigeration equipment (also known as chillers, ice-water machines, chillers, chillers, chillers, chillers, water chillers) that is used by industry to recycle liquid coolers to achieve the required temperature and to increase production efficiency. These liquids can flow through heat exchangers to cool the air or equipment. The vapour compressed water chiller group consists of four main components of the vapour compressed refrigeration cycle (compressors, evaporationers, condensers, dry filters, heat expansion valves), which provide the most important chilling link in the refrigeration process。
Using multiple compressors in combination, each compressor carries an independent cooling circuit, i. E. Evaporation and condensation, which is fully independent; all compressors are under the command of a unified microcomputer control system, turn on and off, and will never interfere with each other, with all the imported originals, with a very low single failure rate and a combination of the above, ensuring that the series is highly stable, and that it is the first to operate continuously over the years select
Basic composition of refrigeration systems
Compressors: compressors are a core component of the entire refrigeration system and a power source for refrigerant compression. Its function is to convert imported electrical energy into mechanical energy and to compress refrigerants。
Evaporaters: the evaporation of refrigerant liquids (in fact boiling) is used to absorb heat-resorting equipment for cooling media heat. Its function in refrigeration systems is to absorb heat (or output cooling). In order to ensure a stable and sustainable evaporation process, the evaporation gas must be pumped away from the refrigerated compressor on a continuous basis to maintain a certain evaporation pressure。
Condensers: in the refrigeration process, condensers act as an output heat and condensers. When high-pressure overheated vapour is released from the chiller compressor into the condenser, the total heat it absorbs in the course of its work, including from the evaporation and chiller compressor, as well as within the pipe, to the surrounding medium (water or air); the refrigerant overheated vapour is recondensed into liquid. (coolers can be classified into three categories depending on the cooling medium and mode of cooling: water cooler, wind cooler, evaporation condenser
Thermal expansion valves: thermal expansion valves are both flow-regulating valves in the refrigeration system and throttle valves in the refrigeration equipment, which are installed between dry filters and evaporation units, and their thermogenic packs are wrapped at the evaporation exit. Its main function is to reduce the flow of liquid refrigerants at high pressure constant temperatures to low-temperature and low-pressure coolant wet vapours (mostly liquids and minor vapours) into the evaporation unit, in which heat is injected for cooling purposes。
Dry filters: water and pollution (oil, iron, copper, crumbs) must be prevented from entering the refrigeration cycle, mainly from the trace water contained in the newly added refrigerant and lubricant, or from the air when the system is overhauled. If the water in the system is not removed, when the refrigerant passes through the throttle (thermal expansion valve or caustic catheter), pressure and temperature drops sometimes condensate into ice, block passages and affect the proper functioning of refrigeration units. Therefore, dry filters must be installed in the refrigeration system。
Receptor: the liquid receptacle is installed after the condenser and is directly connected to the condenser's drain pipe. Refrigerant liquids for condensers should flow freely into the receptacle so that the cooling area of the condenser can be fully utilized. On the other hand, when the heat load of the evaporation unit changes, so does the need for refrigerant liquids, at which point the receptacle acts as a refrigerant and storage agent. For small refrigeration systems, liquid receptacles are often not used, but condensers are used to convert and store refrigerants。
Refrigerants: r22 or r12 are used as refrigerants in most industrial chillers used in modern industries. Refrigerant is the fluid mass in the refrigeration system and its main function is to carry heat and to inhale and heat when the state changes。
The working principles of the bronze source refrigerator
According to the principles of the refrigeration system, low-temperature low-pressure liquid refrigerants absorb heat in the evaporation unit with the surrounding media, evaporate into low-temperature and low-pressure gas, with constant cooling temperature and volume changes during evaporation, cooling of low-temperature low-pressure gas into the compressor, compressed by the compressor, compressed into high-temperature high-pressure high-pressure gas, into the condener, heat exchange with indoor media, partial heat of high-temperature high-pressure gas is absorbed in the evaporation unit, the temperature of the medium is elevated, the high temperature of the cold is discharged from the water/disperstant heat wind, the heat condensor is released into the high-temperature high-pressure fluid flow, after dry filtering by drying the dryer, the flow of the inflating valves, and the flow of the cooler to low-tepressure fluids, and the temperature is changed to the temperature for the heat, thus achieves the entire
Wind-cooler is one of the bronze source cold waters models that cools the constant water to a certain temperature by compressing the cooling mechanism of the chiller to enhance cooling molds or machines, which are used as a single machine, with the dissipation device being the built-in fan, with three inter-connected systems: the refrigerant cycle system, the water cycle system, and the electrical self-control system。
Refrigerant cycle systems:
The liquid refrigerant in the evaporation unit absorbs the heat in water and starts evaporation, produces a temperature difference between the refrigerant and the water, and the liquid refrigerant is completely evaporated into the gas, then inhaled and compressed by the compressor (increased pressure and temperature), and the gas refrigerant absorbs the heat through the condenser to condensate the liquid. Refrigerant cycling is completed by using an expansion valve (or a cavity tube) voltage that becomes a low-temperature, low-pressant refrigerant into the evaporation unit。
Water cycle system:
The pumps are responsible for pumping the water from the tank to the equipment that the user needs to cool, and the cold water takes the heat away and the temperature rises and returns to the freezer。
Electrical self-control systems:
Includes power supply and automatic control。
The power is partly supplied through contact, to compressors, fans, pumps, etc。
