An optimised air source heat pumps (ASHP) using an economised vapour injection (EVI) compressor is integrated in a residential house for field trial and aimed to replace fossil-fuel boiler heating system. Due to the complex of operation strategy and ambient conditions, a good understanding of the EVI-ASHP performance under different operation conditions is essential. This study investigates and analyses the heating capacity and performance of the developed EVI ASHP in field trials for space heating and hot water supply for whole year with variable operation strategies and issues in details. The results of this study provide a solid basis for system operation improvement and scaling up applications of this kind of heat pump in the future.
