When the refrigeration system evaporator liquid Freon into the expansion valve orifice into the evaporator, is vaporization process, which needs time to absorb a lot of heat, so the price is cooled gradually reduce the quality of the plating temperature chilled water machine, in order to achieve the refrigeration cooling effect. So chilled water machine, 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; end plate production structure solid water chilled water machine, heat exchanger tubes and end plates for Expanding style combined wind chilled water machine, and add partitions in the cap so that the flow of refrigerant into a multi-channel, in order to maintain refrigeration oil return, low-pressure refrigerant liquid pipe and tube are working valve is connected, 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. Main features: ◎ intelligent temperature control using PID tuning function, precise temperature control; ◎ exquisite appearance, reasonable structure, the exhaust heat is good; ◎ system tight insulation measures; ◎ stainless steel bath opening for easy cleaning; ◎ optional water level, water flow, high low temperature alarm signal output; ◎ all stainless steel pipe fittings and pumps, reduce pollution; ◎ can be built-in filters, particulate filters and ion purification resin; ◎ good shock absorption, low noise.
