Benchmarking model for the ongoing commissioning of the refrigeration systemof an indoor ice rink

This paper proposes the development of the benchmarking model for the ongoing commissioning of the operation of the refrigeration system of an indoor ice rink. The paper presents (1) the development of models for chillers, ice-concrete slab and controller, (2) the training phase in which the parameters of the benchmarking model are identified based on measurements under normal operating conditions, and (3) the comparison between measured and predicted energy performances. The proposed approach for the development of a benchmarking model can be implemented as application software in the Building Energy Monitoring System of any ice skating rink, if measurements of relevant independent variables are available.
