چکیده
Abstract A comprehensive techno-economic evaluation is evaluated based on an innovative compound ejector-heat pump system with PV/T (photovoltaic thermal) waste heat-driven. The aim of the simultaneous data centre cooling and heat recovery for district heating to reduce residential greenhouse gas emissions. new avoids ejector by combining evaporative-condenser as driving force, considering several low global warming potential alternatives R134a. simulation indicates that proposed presents a remarkable difference in all investigated refrigerants’ overall coefficient performance (COP). Particularly, R515B highest increase COP, 54% 49% modes, respectively. It also provides electricity consumption reduction, 84.1 MWh yearly. Moreover, improves power usage effectiveness (PUE) index from 10 19%. In financial terms, shortest payback period (6.3 years) obtained R515B, followed R515A R1234ze(E).

Limited options for low-global-warming-potential refrigerants
Hydrofluorocarbons, currently used as refrigerants in air-conditioning systems, are potent greenhouse gases, and their contribution to climate change is projected to increase. Future use of the hydrofluorocarbons will be phased down and, thus replacement fluids must be found. Here we show that only a few pure fluids possess the combination of chemical, environmental, thermodynamic, and safety p...
