Abstract

This thesis presents an experimental analysis of a 10 kW air-to-water propane heat pump, as part of the Flaminco research project that has been carried out by Mitis. With regard to legislation concerning heating and air conditioning, propane is a natural gas that could be a substitute refrigerant for polluting refrigerants. The work involes four mains parts: preparation of the HP unit test rigs, experimental campaign, the evaluation of test results and a case study with a load profil. The experimental compaign is mainly focused on the performance in the heating mode of the heat pump, and is also studied in cooling mode. The performance of the compressor and the system is studied with different operating points and against external parameters such as air temperature and water temperature. The case study was made with Dymola using preimplemented libraries. The heating system is composed of a gas turbine, a storage tank, a condensing boiler and a known load. The load profile is given and the models are adapted to match the real machines. The interest is to see the impact of the regulation system on the economic aspect for one year.
