TEWI analysis of high-temperature residential heat pumps.

Résumé

Heat pumps for residential heating constitute a key technology to lower CO2 emissions associated with building heating. The heat pump system capable to replace the current fuel or gas burner heating system needs to provide heat at a high condensing temperature (around 55°C) in order not to change the hydronic network. The heat pump system needs also to provide 100% of heating capacity even for low outside temperature, for Europe typically -15°C. The paper presents a new design of a variable capacity heat pump capable to provide heat at such a high level of temperature by using variable composition blends, and a two-stage system. The seasonal energy efficiency is calculated and a comparison is performed with the current heating system using fuel or gas in order to forecast the gains in terms of CO2 emissions for European climatic conditions and different generation mixes.
