A toolkit for primary HVAC system energy calculation. 2. Reciprocating chiller models.

Author(s) : BOURDOUXHE J. P. H., GRODENT M., LEBRUN J. J., SAAVEDRA C., SILVA K. L.

Summary

The modelling used in the toolkit is oriented toward simple solutions with a minimum number of parameters that are accurate enough for annual energy calculations of whole building systems. Quasi-static models, which are generally sufficient for such applications, allow the user to deal with the part-load regime. The chiller model is developed and documented on the basis of the following elements: an information flow diagram in which a selection of input and output variables and parameters is proposed, three conceptual schemas in which the main physical hypotheses are expressed, and a set of equations derived from the conceptual schemas. The actual refrigerant cycle is taken into account. Heat exchangers and reciprocating compressors are modelled with some realism.
