Investigation of thermal comfort conditions by heat pump Hybridized with phase change Material-based solar desiccant cooling system

Research on the performance and thermal comfort of CO2 heat pump heating system in high altitude area

“…The average annual COP of the 𝐶𝐶𝐶𝐶 2 heat pump heating system at high altitude is 2.95, which is much higher than the COP of other heat source equipments.At high altitude, the 𝐶𝐶𝐶𝐶 2 heat pump can save 41.0% and 59.9% of energy consumption per year compared with conventional heat pump and electric boiler. Compared with conventional heat pumps, gas boilers and electric boilers, the annual operating cost savings are RMB 61,897, RMB 136,317 and RMB 196,400 respectively[8]. Using 𝐶𝐶𝐶𝐶 2 heat pump for heating, the average annual heat cost per square metre is RMB 64, which is much lower than the local heat cost using other heat source equipment.…”
