Plate Heat Exchanger For Refrigeration
Jan 12, 2019

  The plate heat exchanger is an efficient and compact heat exchange equipment. In refrigeration technology, heat exchangers are indispensable refrigeration equipment. Heat exchangers such as condensers, evaporators, regenerators and intercoolers not only account for 50% of the total refrigeration unit in terms of weight, volume and metal consumption.,but also have a significant impact on refrigeration performance. Therefore, strengthening the heat transfer of the refrigerating heat exchanger, reducing the weight and volume, and reducing the metal consumption have always been the development direction of the refrigeration technology. A new type of all-welded plate heat exchanger has been applied in the refrigeration technology. and showing strong growth potential.

  Compared with the shell-and-tube heat exchanger for refrigeration, in addition to the general characteristics of the plate heat exchanger, the plate heat exchanger for refrigeration has the following characteristics:

  (1)Small refrigerant charge, which is conducive to environmental protection and lower operating costs

  The shell-and-tube heat exchanger has a large volume on both the shell side and the tube side. To make the refrigeration system work normally, it is necessary to fill a large amount of refrigerant, and it may also cause environmental pollution. On the one hand, the plate heat exchanger is small in size and small pitch size.

  (2)Low freezing tendency and high frost resistance

  High turbulence can be formed in the plate heat exchanger at low water flow rate, and the temperature distribution is very uniform, thereby reducing the freezing tendency of the chilled water. Even if freezing occurs, it can withstand the pressure generated by freezing, unlike the shell-and-tube heat exchanger, which can easily cause the heat pipe to burst and can continue to be used after freezing.

  (3)Evaporation is thorough and economical

   When the refrigerant evaporates in the refrigerating plate heat exchanger, it is easy to achieve complete evaporation to no liquid level, so in most cases, the refrigeration system does not need to be equipped with a gas-liquid separator. And easy to achieve unitization, easy to install, maintenance and transportation , save costs and reduce costs.
