Experimental Study and Techno-Economic Analysis of Household PVT Heat Pump Poly-Generation System

The PVT heat pump poly-generation system has become a research hotspot in the field of building energy conservation and renewable energy utilization, due to its high efficient and stable time-sharing distributed poly-generation characteristics. In this paper, the household PVT heat pump system is selected as the research object, aiming to meet the building’s various energy demands for heating, cooling, power and hot water, by establishing one set of PVT heat pump poly-generation system. The system operating principles and the design method of roll-bond-PVT unit are introduced in detail. The experimental investigation on the PVT heat pump system was carried out, and the main poly-generation performance during summer was given. The concept of electro-thermal number is proposed to illustrate the design principle and configuration method of household type system. In addition, the techno-economic analysis of the household PVT heat pump poly-generation system was developed. The key economic indexes were proposed, and the technical economy of the system was analyzed and compared. The research results of this paper are of great reference value for the future application of the household PVT heat pump poly-generation system.
