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