Procedures for evaluating the energy performance of hybrid building thermal energy supply systems (Collection of articles)

In this work, the selected articles refer in particular to energy performance evaluation procedures related to heat pumps with mechanical vapor compression integrated in hybrid systems, which supply consumers of the space heating type and the preparation of hot water for consumption in buildings. One category of works is based on energy performance evaluation procedures that call on the isentropic energy efficiency of the refrigerator, but there are also two more recently developed works that are based on the isentropic energy efficiency of the heat pump. Regardless of whether the central core addressed was the isentropic energy efficiency of the refrigerator or the isentropic energy efficiency of the heat pump, the final expression of the COP was the same and the work procedures are similar.

The annual energy performance evaluation procedure takes into account the maximum electrical power of the heat pump, the annual operating period being composed of two sub-periods in which the working stages are slightly different as it turns out from the works presented. It also highlights the way in which the building and the related utilities supply facilities contribute to the energy performance of the hybrid system.
