Résumé

This study aims to analyze the performance of a CO2 heat pump system with an ice-slurry function, including a supercooler, a tri-partite gas cooler, and an ejector. The prototype was developed as part of the TRI-HP project. The performance tests were conducted under different operating conditions in three different modes in the laboratory. The modes are space heating (SH), domestic hot water (DHW), and parallel mode (PA), in which a simultaneous supply of DHW and SH is provided. A numerical model was also developed and verified with the test results.
The results show that the developed heat pump can operate under different operating conditions successfully. It can supply hot water up to 45 °C and 70 °C for SH and DHW, respectively. The system's heating coefficient of performance (COPH) varies between 3 to 6.5 depending on operating conditions.
