Problem Statement: 在HYSYS里 ''将热损失作用于外墙''选项是怎样工作的？ | Solution: 这个决定热损失是直接作用于容器内物流还是作用于容器外墙的选项，只应用于动态模拟。
如果热载作用于外墙，则并非所有热载都会传递给容器内物流，因为容器墙壁本身也会消耗热载从而改变自身温度。
另一个考虑因素是传热速率。在动态模拟中，容器壁温和容器内物流温度有可能是不同的。将热载作用于容器外壁会降低传热速率，因为容器壁本身提供了额外的传热阻力。其程度取决于容器壁的热导和厚度。直接将热载作用于物流不会产生这个额外的传热阻力。
这些作用只在动态里生效，因为在静态模拟里最终容器内物流吸收的热载总是相同的，不管热载是作用于物流本身还是容器外壁因为两者总是处于热平衡状态。

Problem Statement: Why do I get ball valves in my output report when I specify that I want a Globe valve? | Solution: Check your pipe diameters. The ICARUS software will generate a BALL VALVE with a line diameters of greater than 18, even if a Globe Valve is specified. This is because of the LARGE diameter of the pipe line specified. In the ICARUS Technology, Globe Valves are typically used for smaller diameter pipe, availab... |
Problem Statement: How can I turn off my steam tracing manifolds (headers and returns) for some of my piping items?
The headers and returns are already existing, so I don't need more. | Solution: One can delete the subheaders by opening the General Piping Specs in the Project Basis, and choose '-' for the Steam tracing sub-header opt field.
The only caveat to setting this, is that deleting the subheaders will affect ALL components in the project.
An enhancement request has already been made to... |
Problem Statement: Is it possible to assign a COA to conduit and conduit fittings by size, as well as material? | Solution: It is possible to assign a COA that way. We can create COA exceptions based on the material symbol and the “pipe diameter” fields in the allocations form to denote the conduit size. We will have to define new COAs and create exceptions for internal COAs 721 and 722 for conduit and fittings. One caveat is that... |
