Multisource heat pump: data analysis for the first year of operations of a case study.

Author(s) : BUSATO F., LAZZARIN R., NORO M.

Summary

A multisource heat pump heating system was designed in 2007 to equip a new high school building in Agordo (BL), a town in the mountains of northern Italy. The aim of the design phase was that of minimizing the primary energy consumption of the building; a low consumption building envelope was designed, then the best solution in terms of the climatization system has been the object of a detailed analysis conducted by means of dynamic simulation in the TRNSYS environment. The plant was designed to serve for the sole purpose of heating and ventilation, due to the severe climatic condition and the use of building, closed in summertime; moreover the demand for hot tap water is negligible and is fulfilled by means of electric water heaters. Absorption heat pumps were chosen, the heat sources are the solar heat, the exhaust ventilation and the ground heat. Several papers have presented the primary energy evaluation of the different solution and the operational strategies of the plant, as well as the economic analysis. Some of these results are presented in this paper. The building was equipped with a data logging systems surveying all the main parameters of the heating plant. The paper illustrates the data analysis of the first year of operation.
