Air-cooled chiller
Refrigerant circulation system:
The liquid refrigerant in the evaporator to absorb the heat from the water and began to evaporate, a certain temperature difference between refrigerant and the final water, the liquid refrigerant is completely evaporated into gas, after the compressor suction and compression (pressure and temperature increase), gaseous refrigerant through the condenser heat, condenses into liquid. Through the expansion valve (or capillary) into a low temperature and low pressure refrigerant into the evaporator, the refrigerant cycle.
Water circulation system:
Water pump is responsible for pumping water from the tank to the user needs to cool the equipment, frozen water will take away the heat after the temperature increases, and then returned to the frozen water tank.
Electrical automatic control system:
The utility model comprises a power supply part and an automatic control part, wherein the power supply part is provided with a power supply for a compressor, a fan, a water pump, etc. through a contactor.
The automatic control part comprises a temperature controller, pressure protection, overload protection, delay relay, etc. are combined to achieve the automatic start and stop according to the temperature, protection and other functions.
Characteristics of air-cooled chiller
Air cooled chillers can be used on small systems, most of the large units are water-cooled. Water is the initial investment of host, is a little less than air. But with the cooling tower and the engine room, electronic water treatment instrument, is less than what place! Besides years of running, the refrigeration efficiency water-cooled unit will decrease, not air cooling.
Air cooled machine adopts air cooling method, cooling tower, cooling water pump and piping systems necessary for eliminating the cooling water system, avoid water poor area caused by the condenser fouling, the water pipes are blocked, but also saves water resources, water is the air conditioning equipment products, maintenance of the most economical and simple models.
Air cooled chiller should be slightly higher than the water cooled chiller one-time investment, but the annual operation cost is lower than the water cooled chiller room, the construction cost in a variety of air conditioning cold and heat source system is the minimum, maintenance cost is about half the cost of water-cooled or boiler.
The noise and volume of air cooled chillers are larger than that of water cooling. Water cooling units are mostly installed in the basement.
The effect of cold water machine on plastic machinery
1, 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;
2, cold water machine used 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.
The main application of industry chiller: laser technology, welding, plastic molding, injection molding, extrusion, blowing, thermoforming, mechanical cutting and non cutting processing, casting, surface treatment, electroplating, electrophoresis, medical equipment, electronics industry, electronic circuit board production, chip manufacturing, chemical industry, papermaking, pharmaceutical industry, the food processing industry, aluminum, Aluminum Alloy, toughened glass, coated glass production, ultrasonic cleaning, jewelry processing, leather, fur processing, ink production, aquaculture.
After-sale service
For the creation of the brand, increase brand awareness and establish a corporate image, we have the spirit of "all the pursuit of high quality, customer satisfaction for the purpose of" the spirit of "the most preferential price, the most attentive service, the most reliable product quality" principle solemn promise to you:
