Summary

In several situations, simultaneous needs in heating and cooling in buildings can occur (Iow-energy, glass-fronted office buildings). A heat pump for simultaneous healing and cooling (HPS) can be installed advantageously in this kind of buildings. This article, presents a near-industrial prototype of HPS using propane as a refrigerant developed by the Mechanical and Civil Engineering laboratory of Université de Rennes 1 and the Pole Cristal of Dinan. Not only producing hot and cold water simultaneously, this HPS takes advantage of ifs storage system to enhance the overall performance and carry out a more efficient defrosting. Propane (R290) is interesting for its low environmental impact (zero ODP and GWP100=3 kgCO2) and the performance of its thermodynamic cycle. Its high flammability can be mastered by limiting the refrigerant charge like in most domestic refrigerators in Europe. This article presents the refrigeration circuit of the HPS and its operation. The results of a standard test campaign and annual simulations are presented to show the performance improvement of the HPS compared to those of a reversible heat pump from the market.
