Industrial Chiller

After years of practical exploration in the refrigeration industry, the increasing maturity of evaporative cooling technology has provided new ideas for improving the energy efficiency of chillers. Evaporative condensation technology is efficient, energy-saving and green. By reducing the condensation temperature, the energy efficiency of H.Stars chillers is increased by about 20% More and more users prefer evaporative chillers Principle of  evaporative condenser The evaporative condenser combines the condensation process of the water-cooled condenser and the cooling tower with the water cooling process. It uses cooling water to form a thin film on the surface of the heat exchanger, and the water film directly contacts the forced air. The material to be cooled transfers heat to the water film. The water film undergoes unsaturated evaporation and exchanges and transfers heat and mass with the air. Finally, the air takes away the heat. It improves the traditional cooling method...

How to manufacture the shell and tube heat exchanger  I Shell and tube heat exchanger is a kind of heat transfer device, which is composed of shell, tube plate, tube bundle, baffle and cover; How is the manufacture to produce the  shell and tube heat exchanger ? In the manufacturing of heat exchanger, the manufacturing process of cylinder, head and other parts is the same as that of general container manufacturing progress, but the requirements are different. The inspection of materials, drilling of tube plate and baffle hole, welding of cylinder and processing of flange are the key points to the quality. Throughout its manufacturing process, most of manufacturer still use traditional processes, in which the proportion of welding is relatively high, so it is necessary to weld in strict accordance with the welding process, and to detect the weld. The heat exchanger produced by H.Stars Group subsidiary company UAR, has gone through 18 processes. It has been meticulously...
