Panel compared advantages and disadvantages in heat pipe heat exchanger
(a) the advantages
1. The heat transfer coefficient is highTube and shell heat exchanger structure, in terms of strength is very good, but not very ideal, from the standpoint of heat transfer for fluid flow in the shell side there is a baffle plate, shell, fluid, the bypass between heat exchange tube and tube bundle - shell. Through the bypass fluid, not fully participate in heat transfer. And plate heat exchanger, there is no bypass, and corrugated plate can make the fluid in smaller velocity under turbulent flow. So have higher heat transfer coefficient of plate heat exchanger, generally considered a tube and shell heat exchanger 3 ~ 5 times.Accomplish the same heat transfer, the use of tube and shell heat exchanger and the adoption of plate heat exchanger; Plate heat exchanger heat transfer area is only for the tube shell type heat exchange area of 1/3 ~ 1/4.2. The logarithmic mean temperature difference is big -

Hvac equipment and energy saving is the industry development
Since the 1920 s, along with the constant promotion of air-conditioning equipment in our country, the technology unceasing enhancement, hvac industry in China has made considerable development. Currently, hvac technology has already begun to put into application in the field of public buildings and so on, and effective impetus to the development of the domestic hvac industry.
As is known to all, the development of hvac industry is bound to be somewhat to energy consumption, especially air conditioning equipment mostly belongs to one of the larger electric consumption, in this to energy conservation as the theme of the era, the further development of hvac equipment also cannot leave the link of energy-saving technology transformation of ascension. Is the key to the hvac industry of energy conservation and environmental protection equipment research and development, is, of course, as far as possible in the design and manufacture of green environmental protection equipment has reached the purpose of energy s
