Knowledge Of Plate heat exchange

                                The Flow Chart For Refrigeration System Hofmann heat exchanger Plate heat exchanger is efficient and compact heat exchanger equipment, has been widely used in the refrigeration system, and is indispensable refrigeration system equipment that can be used as a condenser, evaporator, regenerator and intercooler for change thermal equipment. Compared with the traditional shell and tube heat exchanger, with high heat transfer efficiency (2 to 4 times of the traditional shell and tube heat exchanger), energy saving, economical, compact structure, easy to disassemble and so on. So it is widely used in refrigeration systems. However, if the plate heat exchanger in different refrigeration systems cannot get the correct use and maintenance, it cannot play its role and use normally, which is not only diseconomy, but influence production to bring economic losses to the ente...

Hofmann Under normal operating conditions, the more options are symmetrical flow path plate heat exchangers, because when the volume flow of the two media fluid is roughly the same, the choice of equal arrangement is more reasonable. While the difference of the medium fluid flow on both sides is large, the small side of the fluid should choose multi-process layout. In general case, the change side of plate heat exchanger is always a single process. Multi-process plate heat exchanger, if not special needs, generally take the same number of flowways for the same liquid. In the case of certain pressure drop, the multi-process arrangement will have a corresponding lower pressure drop for each measurement, so the flow rate will become low. In addition, multi-process layout is also an important factor of different average heat transfer temperature, which should be avoided or reduced as much as possible. In recent years, with the diversification of plate heat exchang...
