Experimental study on the performance of an air-source multi-functional heat pump for commercial buildings

This paper presents a novel air-source multi-functional heat pump (AMHP) for commercial buildings. The AMHP integrates refrigeration, space heating, water heating, and heat recovery functions into a single device, offering a comprehensive solution for commercial building heating and cooling needs. The objective is twofold: to enhance energy efficiency and to reduce environmental impact. A series of experiments were conducted to assess its performance across a range of operating modes and ambient conditions. The findings indicate that the AMHP can function reliably over an extended period, thereby achieving substantial energy savings. This research provides a pragmatic and energy-efficient solution for a range of applications in commercial buildings. Further system design optimization is proposed for subsequent studies.
