Plate heat exchangers stand out in refrigeration technology
May 23, 2019

Plate heat exchanger is an efficient and compact heat exchange equipment. It has been widely used in petroleum, chemical, light industry, electric power, metallurgy, machinery, energy and other industrial fields, and has become a highly competitive variety in the heat exchanger family. In particular, a new type of all-welded plate heat exchanger is used in refrigeration technology and has shown strong development potential.


Compared with the shell-and-tube heat exchanger for refrigeration, the plate heat exchanger has the general characteristics of the plate heat exchanger and the small refrigerant charge, which is beneficial to environmental protection and lower operating cost; The anti-freezing performance is high. Due to the low flow rate of water, high turbulence can be formed in the plate heat exchanger, and the temperature distribution is very uniform, thereby reducing the freezing tendency of the chilled water. Even if freezing occurs, it is more able to withstand the pressure generated by freezing, unlike the shell-and-tube heat exchanger, which can easily cause the heat pipe to burst and can be used after freezing.


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 can save costs and reduce
