Re: Fluid change (not in a predefined scheme)

Good afternoon, the same problem has recurred, as unfortunately unresolved. I tried to change a predefined fluid with the R245fa, to perform liquid-liquid thermal exchange with a plate heat exchanger. I would, therefore, have the following technical doubts: What is the correct procedure for entering...

Programmable controller (Function and MATCHFLOW)

Good morning, I contact you for a doubt regarding the realization of the programmable controller. Starting from the material provided in Polysun's Tutorial_EN I created a new controller, however due to the absence of some practical examples I cannot find the error. Starting from the attached file, I...

Re: Mass flow rate error (external heat exchanger) Thema ist als GELÖST markiert

Good morning, The aim of the project is to insert an external plate heat exchanger (no mixing) and exchange heat from the solar fluid loop with an organic fluid under pressure (therefore in a liquid state) in another loop as in the figure. It would, therefore, be a heat exchange in an external heat ...

Re: Mass flow rate error (external heat exchanger) Thema ist als GELÖST markiert

Good morning Nathanael, the two loops contain different fluids and so I inserted two different pumps because there are two different flow rates. I would simply like to simulate a thermal change between these two different loops and therefore I want to simulate them by interposing an external heat ex...

Re: Fluid change (not in a predefined scheme)

In my model I will use a fluid under pressure, so the state conditions of the fluid are different. Furthermore, the fluid could vaporize. What would be the logic of entering the parameters in order to insert them correctly? I ask this question because in the catalogs the fluid data refers to environ...

Mass flow rate error (external heat exchanger) Thema ist als GELÖST markiert

Good morning, I found a problem in a simple configuration. In the attachment, there is a file (separate system) in which there are 2 different loops of 2 different fluid. This configuration works without any problems. Then I try to insert an external heat exchanger between the 2 loops and the follow...

Hot source and problem of too many cold input

Good afternoon, in the solution presented in the attachment, I would like to insert in point 3 a hot water source (95 ° C) and consequently cold in 4. Currently, as input I found only a cold source. Is there a possibility to change fluid temperatures? Furthermore starting the simulation the followin...

Fluid change (not in a predefined scheme)

Good afternoon, thanks to your help in previous topics, I can change the fluid in circulation. However, as can be seen in the attachments, the modification takes place only if implemented in a Wizard proposed by the software. If starting from this I apply some plant modifications (insert new pipes o...

Doubts in the sizing of storage and heat exchanger for swimming pool for shower, modoyfy parameter error and control Thema ist als GELÖST markiert

Good morning, I'm an Erasmus student in Portugal. I have 6 doubt related to my simulation. I apologize previously for the error description in Portuguese, but the software was installed in the Portuguese language. In attachment there is the plant image and the error code. This are my doubts: 1st: Di...

External heat exchanger with ORC fluid Thema ist als GELÖST markiert

Good morning, I'm a student who is using Polysun software, version 11.0. I have two doubts. I would like to make a simulation in which an organic fluid (other than the default water) is present on one side of the external heat exchanger. How could such a simulation be done? I tried to insert the inl...
