What is Shell And Tube Heat Exchanger?

Heat exchanger is the most important part of the refrigeration unit, its quality and manufacturing process determine the heat transfer efficiency and service life of the unit. And on behalf of a manufacturing enterprise has the core technology and has the intellectual property rights and the ability to create.

What is the role of Fixed Tube Heat Exchanger in Water Chiller?

In the whole cycle of the chiller, the role of high pressure in the condenser is the heart of the whole system. And, the condenser is the device that outputs heat, and the heat drawn from the evaporator even the heat converted from the work consumed by the compressor is taken away by the cooling medium in the condenser.

According to the spatial orientation of the shell and heat transfer tube bundle, the shell and tube condenser can be divided into two types: vertical and horizontal.

But no matter which type, the cooling water takes the tube process and the refrigerant takes the shell process, that is, the high temperature and high pressure refrigerant vapor cools on the outer surface of the heat transfer tube, condenses and converges to the shell. The reason for this arrangement is that the average heat transfer coefficient between cooling water and tube bundle is generally higher than the average heat transfer coefficient of refrigerant vapor condensation, which requires a larger heat exchange surface for condensation; in addition, in order to keep the pressure of high temperature and high pressure refrigerant vapor within a certain range, a larger space is also required.
