Résumé

In low-heating-energy buildings heat pumps have become an attractive heating system, due to a notable reduction of the space heating requirements and the introduction of low temperature heating systems. Comfort cooling becomes also more important, especially in lightweight buildings with large south-oriented windows, which partially tend to overheat in summer. A heat pump has the unique feature that heating and cooling can be provided with the same system and also at the same time. Thus an integrated heat pump system with the functions heating, cooling and preparation of domestic hot water is an interesting solution for the energy supply of low-heating-energy buildings. At the Institute of Thermal Engineering, Graz University of Technology, a prototype of an integrated heat pump using the natural refrigerant R744 (CO2) has been developed. A detailed experimental analysis of the prototype in different modes of operation has been performed and is presented in this paper. The results of these measurements are used to validate a steady-state model of the system, which will be applied to obtain performance maps of the heat pump in different modes of operation.
