Knowledge Of Plate heat exchange

Vertical shell and tube condenser The main features of the vertical condenser are: 1)     Due to the high cooling flow and flow rate, the heat transfer coefficient is high, generally about K = 600 ~ 700 (kcal / m2? H? ℃ ). 2)     Vertical installation covers small areas, and can be installed outdoors. 3)     Cooling water flow directly and have high flow rate, so not need high water quality, the general water can be used as cooling water. 4)     Scales in pipe can be easy removed, and do not have to stop the refrigeration system work. 5)     But in the vertical condenser, the rise temperature of cooling water is generally only 2 ~ 4 ℃ , logarithmic average temperature difference is generally about 5 ~ 6 ℃ , so need much water. And because the equipment is placed in the air, the tube is susceptible to corrosion and is easier to find its leaking. Shower type condenser ...

                                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...
