Speaking of energy efficiency indicators, there is an urgent need for a heat exchanger design software
Thread Content
The new Regulations on the Safety Supervision of Special Equipment came into effect on May 1 this year, and energy conservation has been established as a fundamental national policy. Therefore, designing heat exchangers is no longer just about meeting strength requirements; energy efficiency criteria must also be established. Is there any friend willing to share a shell-and-tube heat exchanger design software for use when needed? First, I would like to express my thanks here!
There are currently two internationally widely used software programs for the design of shell-and-tube heat exchangers: HTRI and HTFS+. I am pleased to see that **stricter regulations are being established for special equipment such as heat exchangers; energy conservation should indeed become a standard requirement. Traditional process engineers often design heat exchangers based on experience, and to be safe they leave large margins in the design, resulting in significant waste. The greatest advantage of using software is optimization; it helps engineers determine which type of heat exchanger is the most cost-effective to use while still complying with safety regulations. I believe that as efforts to save energy increase in our country, heat exchanger software will play an increasingly important role. The poster can compile examples encountered in actual work and post them on the forum for discussion.
I work in the field of chemical processing equipment, and in my daily work I often encounter situations where clients are unwilling to provide their process parameters, such as inlet and outlet flow rates and temperatures. Unless it comes to the working temperature required for strength calculations and the name of the medium necessary for material selection, the user will only tell you what type of heat exchanger is needed, what material it should be made of, and what its heat exchange area should be, without providing any other parameters. As for the calculation of wall temperature, it relies entirely on empirical estimation. The users’ approach is understandable – after all, process secrecy is important – but it creates difficulties for us who are involved in equipment design: previously it was sufficient as long as the users were satisfied, but now compliance with energy efficiency standards is required. I really don’t know how to deal with such problems in the future.
