Plate and shell heat exchanger in AC on the application of hot water-Qingdao Ruipute
Click number:- Release time:2020-06-09

The following is a case study of a plate and shell heat exchanger in a practical application in air conditioning hot water, where we have analyzed actual customer conditions. The most suitable equipment was designed and selected. Customers in the use of the process of the problem has been a certain solution.


Use of conditions: the heat transfer system is mainly different process hot water steam heat exchange, 90 ? and 105 ? process hot water, the use of traditional hot water. In the case of the shell-and-tube type heat exchanger, the steam heating on the steam side is not continuous, resulting in steam impingement and internal leakage, which seriously affects steam condensation. Water Return System. The condensate returns to the boiler make-up water tank, and the internal leakage causes the hardness of condensate to be unqualified and all of it is discharged, causing a lot of heat energy and water waste.

The main problems:

1. leakage, regular inspection of condensate, found that the water quality is not up to standard, process water leakage, had to be discharged, extreme Waste; sometimes it is not found in time and can cause contamination of the tank and boiler.

2. Scaling, large scale is found when removing and cleaning maintenance.

3. Occupy a large space, not conducive to equipment expansion.


Caused by the analysis of the above reasons:

1. process water often start and stop, steam control valve switch more frequently, the impact of the tube heat exchanger. The influence of thermal stress is obvious, and the weld is prone to cracking, causing intermixing of media and pollution of condensate.

2. Quality problems, resulting in scaling, affecting the efficiency of heat transfer, the need for frequent disassembly and cleaning, time-consuming and laborious, high economic costs

3. Tube heat exchanger The low heat transfer coefficient, low efficiency, and large area of land.


Qingdao Ruipute plate and shell heat exchanger for the plate and shell type disadvantages made targeted improvements, it can be said, completely make up for its shortcomings.


First of all, the core component of the heat exchanger is a fully welded circular plate group, no adhesive strips, high temperature resistance and impact resistance is very strong, working temperature widely, on the Means the housing can withstand greater thermal expansion and contraction. The robust pressure housing ensures the safety of the housing and maintains stable heat transfer performance even in harsh operating environments. The effects of thermal stress are completely overcome, avoiding contamination and downtime caused by leaks.


Second, the use of materials and processes that are not easy to scale, making the scaling rate lower, reducing maintenance and cleaning time.


Finally, the plate and shell heat exchanger heat transfer efficiency is high, in the same heat transfer of small, its volume is much smaller than the shell and tube heat exchanger, to be able to expand the scale of production for the future to prepare.


After using our plate and shell heat exchanger products, customers regularly check the water quality, no more leakage phenomenon is found, condensate has been fully Recycling, avoiding waste. No need for frequent disassembly and maintenance, saving labor and material resources.
