Module-based AHU model #310

Closed KFinkbeiner closed 4 years ago

marcusfuchs commented 7 years ago

@KFinkbeiner Thanks for starting this issue. Could you please add 1-2 sentences of description to inform everyone about what the aim of this development is?

KFinkbeiner commented 7 years ago

Firstly, the aim is to develop a modular model of an air handling unit (AHU). The modular modeling approach enables the modeling of AHU with different component configurations in a time efficient manner. Further, the modular modeling approach simplifies the on-going development of individual components, as well as the entire AHU. Secondly, the model should be suitable to the AixLib low-order building models. Here, a map based (states of moist air – Mollier diagram) modeling approach is pursued, which promises a reasonable computation time.

Could we close this issue and have further discussion in #360 to prevent similar discussions in several issues, @KFinkbeiner?

KFinkbeiner commented 7 years ago

Sorry for missed comments. The current status of the development is:

  1. A list of all AHU components is prepared
  2. Refering the thermodynamic function (coolin, heating...) and the used technology, the list is sorted
  3. The component performance is identified in the Mollier diagram and is described by corresponding equations
  4. First component models are implemented and we run first tests

@KFinkbeiner : I am not sure what the current status is here. But I set the milestone to next version which is due on 30 May 2018. Maybe you can solve this issue (partially) at the institute's hack day ;)

LauraMaier commented 5 years ago

@KFinkbeiner Maybe you can work on this issue at the institute´s hack day tomorrow :)

KremerMartin commented 5 years ago

@KFinkbeiner As we have some models ready, only needing some refinement, this maybe could be a task for the hacktober. ;) Especially on the Hackday next week. :)

Dawac commented 4 years ago

@KFinkbeiner : As there is no branch linked to this issue and the topic seems to also be discussed in #360, we will close this issue on the upcoming Hackday

KremerMartin commented 4 years ago

@Dawac I will open a new issue. On the upcoming Hackday, I will provide the actual development of the new modular equation-based AHU model on the regarding branch. @KFinkbeiner Maybe we could work together on this, if you've got time on the next Hackday. ;)
