Cold medium circulation machine, industrial circulating water cooling equipment system operation is through three interrelated systems to work: the refrigerant circulation system, water circulation system, electrical control system.
The liquid refrigerant in the evaporator refrigerant circulation system to absorb water and heat and began to evaporate, formed a certain temperature difference between refrigerant and water * * * end, the liquid refrigerant is completely evaporated into gas, after the compressor suction and compression (pressure and temperature increase), gaseous refrigerant through the condenser (air / water) to absorb heat, condensation liquid. Through the expansion valve (or capillary) after the throttle into a low-temperature low-pressure refrigerant into the evaporator, complete the refrigerant cycle process.
Water circulating system water pump is responsible for pumping water from the tank to the user needs to cool the equipment, frozen water will heat away after the temperature rise, and then return to the freezer.

General 10P above the use of water cooling, 10P following the use of air-cooled heat.
Air-cooled industrial chiller is generally a whole machine, and the evaporator, compressor and condenser are done together. For the air-cooled industrial cold water machine with a little power, it is required to consider the heat dissipation problem of the condenser cooling fan. In the air conditioning plant application, the overall machine needs to set the exhaust duct to the heat of the cooling fan out of the outdoor.
Air cooling type industrial cold water machine can also be done in the composition, the condenser directly into the outdoor (outdoor unit), the evaporator and the compressor on the indoor (indoor unit). However, considering the cooling medium in the process of heat transfer between the condenser and the evaporator and other issues, indoor and outdoor machines in the distance between the * * * good control within 6 meters, in addition, the transmission of cold medium of copper pipe need to do thermal insulation. Power cable and control cable and copper wiring fan can be together, so air-conditioning plant just pipe openings can wear. For the application of small flow and small heat capacity air cooled chiller industrial applications, generally use the overall direct use, at this time can not take into account the heat. For air cooled chiller and large flow and big heat, can be split.
Air cooled condenser cooling machine and its effect is affected by seasonal climate changes in the external environment is influenced, and the chiller, the tower cooling effect is stable, it is necessary to determine the set of towers, poor mobility. Application of cold water machine used in the plastic processing machinery mould cooling, can greatly improve the plastic surface finish, reduce plastic surface marks and internal stress, the product does not shrink, not easy to deformation, plastic products, mold release, accelerate product shape, thereby greatly improving the production efficiency of plastic molding machine; cold water machine application in CNC machine tools, coordinate boring machine, grinding machine, machining center, machine and all kinds of precision machine tool spindle lubrication and hydraulic system of transmission medium cooling, can accurately control the temperature and reduce the thermal deformation of machine tools, improve the machining accuracy of machine tool.

Industrial circulating water cooling equipment, cold water cycle machine, refrigerant cycle machine, cycle refrigeration units in the use of the various industries and the selection of features
One, UV curing machine: characteristics:
Stepless dimming + water cooling + metal halogen lamp + cryogenic + = energy efficient, indoor lamp adopts water cooling (chuanben chiller chilled water) + air-cooled heat insulation tube below the installation of quartz glass, reduce reducinglow surface temperature, protect dry goods are not heat distortion, prolong the service life of the lamp tube; CBE water cooling series: suitable for offset printing machine, printing machine, flexo printing machine, coating machine and other printing equipment at home and abroad. Offset printing machine, such as: Germany, Heidelberg, Japan Roland KBA, KOMORI, MITSUBISHI, Sakurai, Ming Liang, Biden etc.. Gravure printing machine such as: Bost, Rudi, the Swiss cup Italy Xi'an black, Nakayama Matsunori used part of the customer: Baoding City special light source electrical appliance factory; Chi Sheng (Guangzhou) Technology Co., ltd.;
Two, ultrasonic cleaning machine:The study shows that the effect of ultrasonic on the liquid, rupture of each bubble in liquid will produce great energy of shock wave, the equivalent moment of high temperature and high degree of hundreds of thousands of atmospheric pressure, this phenomenon is called "cavitation", ultrasonic cleaning is the shock waves generated by liquid bubble to wash and scour workpieces inside and outside surface of the effect. Second ultrasonic wave propagation, the liquid in the liquid, and the cleaning tank in the ultrasonic frequency vibration, and the liquid cleaning tank has its own inherent vibration frequency, the vibration frequency is the frequency, so people can hear the hum. Water cleaning lotion temperature suitable for 40-60 * * * C, especially in cold weather if the low temperature of liquid cleaning effect is poor, the cleaning effect is poor. So there is some cleaning machine to control the temperature of the cleaning tank outside around the electric heating wire, when the temperature rises after cavitation occurs easily, so the cleaning effect is better. When the temperature continues to rise, the gas pressure inside the cavity increases, and the pressure drop is caused by the impact of the two factors. All the factors, chuanben brand industrial cleaning agent can reduce water temperature, condensation of gaseous cleaning agent, effectively prevent the volatilization of cleaning agent
Three, the plastics injection molding extrusion blowing molding film, rolling film standard industrial chiller can be applied in the industry. The injection mold cooling the melted plastic particles by injection mold, condensation, mold ejection molding plastic workpiece, in the continuous production process is required for cooling the plastic mold, to shorten the setting time, improve the dimensional accuracy, surface quality and molding quality. Frozen water temperature requirements: 6... 18 degree of freezing water temperature requirements: + 0.5K or + 2K chiller capacity of the injection molding machine injection molding machine (usually called "safety"), the greater the amount of injection, the required cooling capacity is also large. Usually in the injection molding machine clamping force "tonnage" nominal, it will need to "tonnage" into "Oz", but "tons" and "Oz" is not a one-to-one comparison table below is only the general condition of the transformation, and there is a certain upper and lower deviation. Extrusion extrusion molding pipes, trunking, cable and all kinds of plastic profiles. The raw material heated to melt molding after a cold bath cooling, freezing temperature of water bath must be kept constant. Due to high production speed, because the surface need large capacity unit. Because the frozen pool is large enough, the unit can not fit the water tank.
Blowing the main production of various types of bottles of mineral water bottles, bottles of steam. Compressed air drying - blowing bottles with a clean, dry compressed air, the use of industrial water cooling machine can be used as a source of cold water can be removed from the compressed air in the water. Mould cooling - cold water can accurately control the mold temperature, improve product quality, improve the production efficiency of compressed air drying and cooling of the mould can be used with a chiller as the cold source thermoforming products for less * * * common containers, such as yogurt cup plastic heated extrusion mold under constant frequency, constant temperature is very important the chilled water temperature range, the requirements are very high, so we need a proportional valve from the cold water but to accurately adjust the temperature. The hydraulic system of mold, mold, injection to hydraulic system, hydraulic oil hydraulic pump energy absorption temperature rise, usually oil temperature not higher than 60 DEG C. Cooling water temperature is about 27 degrees Celsius more appropriate, due to the requirements of water temperature and mold is not the same, so the need for electric water valve and mold cooling circuit separate or need an independent cooling system.
Four, machinery industry of laser technology in laser (laser) system of laser source, light controller and electric control cabinet may require additional cooling. The freezing water temperature is usually 15... Between 22 degrees Celsius, the accuracy requirements of frozen water is usually + 1K or + 2K. Part of the equipment may require + 0.5K, in addition to some equipment on the freezing water conductivity, corrosion resistance, and so there is a certain requirement. In the laser system, there is a certain requirement for the water temperature in the start, so it is needed to increase the electrical heating in the water circuit. The beam controller in some systems will require an independent cooling circuit. For the special application of the laser system, it can be designed to meet the different requirements of industrial water cooling machine. Welding electrode, welding and cutting etc need cooling furnace. Such as large, medium and large welding torch nozzle cooling; gold, silver hand decoration processing of electric furnace cooling, etc. usually small to medium water chiller. Internal and external circulation pump system or closed water tank system. Many machining tools (machining center, lathe, milling machine, drilling machine, etc.) need cutting tool or high speed rotation of the spindle to produce heat, in the cutting process also produces a lot of heat. Such as the spindle, cutting fluid, lubricating oil, hydraulic oil, etc. in the part of the machine cabinet usually cooling. Non cutting machines, such as electric spark machine, polishing machine, grinding machine, etc.. The use of the chiller water system adopted by some iron plug, because some required the installation of filters. Internal and external circulation pump system or closed water tank system.
Chuanben brand industrial chiller selection 1, through the cooling water inlet and outlet temperature (oil) to calculate the calorific value of Q = SH * De * F * DT / 60 Q: heat KW (Note: heat chuanben 1P chiller is about 3KW) than SH: hot water heat is 4.2KJ/Kg*C (4 thousand and 200 MJ / kg * Celsius) oil heat is 1.97KJ/Kg*C (1 thousand and 970 MJ / kg * degrees Celsius) the proportion of 1Kg/L De: the proportion of water (1 kg / L) the proportion of 0.88Kg/L oil (0.88 kg / L): F (flow LPM L/min L / min) DT: cooling water (oil) import and export (export - import temperature difference note: 60 / temperature) is used to flow into the L / L / S; 1kW = 1kJ/s; 1 cases: the cooling water is 15 degrees, 20 degrees of water, flow rate of 20 L / min calorific value Q = 4.2 x 1 x 20 x 60 = 7KW (20-15) / choice chiller cooling capacity when used to 20%-50% CBE-03 can be increased properly W example 2: the inlet of the cooling oil is 18 degrees, the oil is 26 degrees, the flow rate is 15 L / minQ = 1.97 x 0.88 x 15 x (26-18) = /60 2.6KW (oil) using the cold water chiller capacity can be properly increased by 2, 20%-50% can use CBE-02A power equipment, heat, such as for estimation of a spindle cooling, cooling capacity according to the 30% estimate of the spindle motor power required refrigeration unit. For example: 15KW motor, refrigeration unit, optional 4.5kw or 5.8kw cooling capacity; B, injection molding machine can be estimated by 0.6KW per ounce cold or every 80 tons of 3KW refrigeration quantity accounting; 3, through the water (oil) Shenglai box temperature calculating heating value Q = SH * De * V * DT / 60 KW SH: Q: heat than hot water heat is 4.2KJ/Kg*C (4 thousand and 200 MJ / kg * Celsius) oil heat is 1.97KJ/Kg*C (1 thousand and 970 MJ / kg * degrees Celsius) the proportion of 1Kg/L De: the proportion of water (1 kg / L) the proportion of 0.88Kg/L oil (0.88 kg / L V (L): water capacity L) including water tank and piping in the total water capacity of DT: water (oil) * * * large temperature within a minute L / 60 note: for Wen Sheng degrees Celsius / into Celsius / sec; 1kW = 1kJ/s; note: when measuring water (oil) box temperature is slightly lower than the environment temperature and equipment in large * * *; Work under the load. Example: water tank volume 3000L*** large water temperature 0.6 degrees / minutes heat Q = 4.2 x 3000 x 1 x 0.6 x / 60 = 126KW the choice of cold water chiller can be appropriate to increase the 20%-50% can choose CBE-50W;
Note: the temperature of refrigeration and temperature and water chiller, 1 different change; 2, the actual equipment heat will also because of the different parts, mold, parameter changes; 3, the use of cold water machine after the temperature drops, connecting pipe, water tank, oil tank, mould, spindle, surface temperature of equipment below the ambient temperature, so the result will absorb heat load increases; 4, in the actual application of industrial cooling in many cases can not be accurately calculated using the above method, then only through the empirical data and the similar equipment analogy estimation method.
