Implement a moving boundary condenser for improved part load modeling

Open fwitte opened this issue 1 year ago • 1 comments

Especially in heat pump or refrigeration machine applications, the condenser component may have a significant heat transfer share from the desuperheating of the working fluid. The heat transfer coefficients for desuperheating and condensation usually differ strongly, therefore using an overall kA (UA) value for the complete process to model part load may not be correct. Therefore an approach is implemented with a moving boundary, which will split the virtual area of the condenser into a desuperheating and a condensation part. The split will happen proportionally to the heat transfer of each subprocess and be validated using reference data.

Another interesting approach would be following this publication: https://www.sciencedirect.com/science/article/pii/S1359431114011570

This will serve as basis for new heat exchanger models. Another one, i.e. a 1-D heat exchanger including pressure losses will follow.
