From jon at esru.strath.ac.uk Thu Jan 12 09:20:32 2023 From: jon at esru.strath.ac.uk (Jon Hand) Date: Thu, 12 Jan 2023 09:20:32 +0000 Subject: [esp-r] Going off-piste on early stage environmental control explorations Message-ID: I am a firm believer in the use of limited attribute environmental control descriptions to explore patterns of performance prior to a heavy investment in model detail. Can a room be comfortable with a controller which includes a 10 minute rest in its duty cycle? Would multiple stages of heating provide better control at a lower running cost? Commissioning is indicating that there are serious offsets in how the thermostats are tracking temperatures - none of these need wait for the detail stage. I have created another video which starts with matching the simulation time step better to the ?sense of time? of the control logic (what could possibly go wrong with a sticky ON-OFF controller?) And once that is dialled-in I look at controllers matched to the foibles of particular control regimes and see how they can be used to answer some of these early-stage questions. Might make a good background resource for workshops or classes as well as checking reminding ourselves that 'just because it didn't crash... it does not signal that it is a good rendition of control X'.... https://youtu.be/w8ECqcVtFDA Feedback appreciated on this as well as other videos in the series.... -Jon -------------- next part -------------- An HTML attachment was scrubbed...

First - there only seem to be 4 verticies in the description. Should there not be more points? And the mass seems to be low. Can you supply a sketch of what the predefined person should look like? What do you intend it to be used for? A visual study or to represent the mass of a person (or both)? If you created a thermal zone that only included the various entities associate with the 'person' and sent it I could test creating a predefined entity to see if there are errors. Also if you attached the predefined database it would be helpful for others to look at.

The error is happening when it is trying to compose a menu. We would need to do some debugging while attempting to create the same network to get past this. To help us with this can you send a sketch of the network you wanted to create along with the names of the entities that you tried to use so the fault can be duplicated? Until this can be done why not try an alternative approach? It seems like a simple network. Is there a reason you do not use a simple box model of a thermal zone with it? This will us the much more common bps simulator to solve both the zone and the flow network - so you get the dynamics.

The focus is on sizing and evaluating the performance of the ventilation system and its components, and the idea is to configure the flow network in enet and simulate it in mfs without including the building and plant, at least at the beginning. Initially, the idea is to understand how enet and mfs work together. The flow network configured in enet is: [image: image.png] The configuration file sup_vent is attached to this mail.

Grobe) Date: Wed, 8 Nov 2023 19:47:51 +0100 Subject: [esp-r] 2d/3d heat conduction Message-ID: Dear all, ESP-r's capability to model heat conduction not only orthogonal to surfaces, but also refined in 2d and 3d, is mentioned several times in the documentation. However I have not been able to find any information about how to do that so far. Is there any documentation, publication, example introducing this feature available? Best, Lars.

Years ago, I tried getting the feature to work, however, to no avail, as far as I recall. So don?t hold your breath ? Best Achim > On 8 Nov 2023, at 19:47, Lars O.
