Improve model for direct fired double-effect absorption chiller #1325

Closed shanshanhsieh closed 5 years ago

shanshanhsieh commented 6 years ago

The current model in CEA for direct fired double-effect absorption chiller is composed of one double-effect absorption chiller and a gas burner.

During operation, the heat sources are either produced by evacuated tube solar collectors or gas burners, similar examples are seen in literature: https://www.sciencedirect.com/science/article/pii/S1359431104001255#FIG1 https://www.sciencedirect.com/science/article/pii/S0038092X10002033#sec1 https://www.sciencedirect.com/science/article/pii/S0960148104000424#TBL6 http://www.maya-airconditioning.com/eng/pdf/chmg/CH-MGCE%20CH1%209-1(EN).pdf

The model for gas burner is a duplicate of gas boiler at the moment. Possible improvement measures are either:

  1. find a better gas burner model (which consider flame temperature and the heat exchanger)
  2. make a new model for direct-fired double-effect absorption chiller

2 years here, we will not have it anytime soon. Closing it.
