The COP vs. the Temperature Level in the Space Heating System Figures 5.15 through 5.17 show the measured COP for the CO2 heat pump unit as a function of the high-side pressure at fixed set-point for the hot water temperature and varying supply/return temperatures for the space heating system. The measured values come from the same measuring series as presented in Figures 5.7 through 5.9. Figure 5.15 The measured COP at 60oC DHW temperature and varying supply/return temperatures for the SH system. 5 – Experimental Results 4.0 3.5 3.0 2.5 7.5 8.0 8.5 9.0 9.5 10.0 Gas Cooler Pressure [MPa] 3.98 3.89 3.86 33/28°C, 60°C 35/30°C, 60°C 40/35°C, 60°C 4.0 3.5 3.0 2.5 7.5 8.0 8.5 9.0 9.5 10.0 Gas Cooler Pressure [MPa] 3.57 3.75 3.50 33/28°C, 70°C 35/30°C, 70°C 40/35°C, 70°C Figure 5.16 The measured COP at 70oC DHW temperature and varying supply/return temperatures for the SH system. 125 COP [-] COP [-]PDF Image | Residential CO2 Heat Pump System for Combined
