When the refrigeration system evaporator liquid Freon into the expansion valve orifice into the evaporator, is vaporization process, which need to absorb a lot of heat when the wind chilled water machine, so the price is cooled fluid temperature gradually reduced in order to achieve refrigeration cooling effect. Well, according to media types can be divided into the cooled cooling liquid (water) in the evaporator (dry evaporator) and the evaporator cooling air used (Table cold evaporator) two categories. Here introduces the chiller evaporator refrigeration system used generally for dry shell and tube evaporator. As shown, the refrigerant evaporated in the heat exchange tubes, the water in the shell and tube side of the flow, to increase heat exchange efficiency, is provided in the shell and tube side 2mm thick flap, so that the water flows back and forth around, to achieve the purpose of the ice produced brine, the container shell is made of 6mm thickness above the steel pipe, can withstand 10 Kg / cm, external to the PE foam board insulation. Seamless and efficient heat exchange tube with copper, the embossing process processed into the internal thread-fin tube to increase the heat transfer area, and improve the efficiency of heat transfer, pressure 20 Kg / cm; frozen solid end plate production structure Water, heat exchanger tubes and end plates for Expanding style combine, and add partitions in the cap so that the refrigerant flowing water into multiple water-cooler to keep the frozen oil return, low-pressure refrigerant liquid pipe and tube are working valve connection, the total heat transfer coefficient should be able to tolerate 0.086 M2 ℃ / KW fouling factor, pressure drop through the evaporator, the water does not exceed 6.5mAq. Products Chiller mainly to give the product or equipment to provide chilled water to achieve cooling purposes. Both chillers are required for cooling with cooling towers, but because the water-cooled chiller box built water tanks and pumps, so the installation of the tank type water-cooler, users only need to chillers and cooling towers linking piped water can be put to use. And in addition to open chiller equipped with cooling towers, but also need to increase the pump and double stainless steel water tank insulation before using chilled water machine, Shanwei City, chilled water machine, water-cooler-long refrigeration industry by the Dongguan City-long Refrigeration Electrical Equipment Engineering Limited.
