Résumé

This study presents results of two experimental campaigns on a 30 kW air source CO2 heat pump prototype for domestic hot water (DHW) production. The prototype has been realized, tested and optimized within the NxtHPG (Next Generation of Heat Pumps working with Natural fluids), 7th Framework European project. The project aims to reach higher efficiency (10-20% SPF improvement) and lower Carbon footprint (20% lower TEWI) than the current state of the art HFCs/HFOs or Sorption heat pumps, with costs very similar or slightly higher than the latter systems (10%). The tested CO2 heat pump has been designed to produce water at 60 °C/80 °C starting from a return temperature in the range 10 °C/55 °C (winter) and 20 °C/55 °C (summer). First experimental campaign was performed to determine possible issues and potential improvements to be applied on this prototype. In the second experimental campaign, after the required modifications of the prototype, the measured performance, COP and heating capacity, have been in line with objectives. In addition, useful information have been obtained to make additional modifications to further improve the heat pump performance.
