The School of Energy and Machinery Engineering, Shanghai Electric Power University, has achieved a series of important results in the field of solar photovoltaic thermal use

Recently, Associate Professor Zhang Tao of the School of Energy and Machinery Engineering of Shanghai Electric Power University uses the first author and communication authors' academic papers "Preliminary Investigation on the Switching Time of a PhotovoltaRTARTED Heat-PUMP/Heat-PITE-PITE-PIET-PIAT-PIAT-PIAT-PIAT-PIAT hybrid system”（Applied Energy, 2022, 324: 119693）、“Seasonal-regulatable energy systems design and optimization for solar energy year-round utilization”（Applied Energy, 2022, 322: 119500）连续被国际能源类顶级期刊Applied Energy (In the first district of the Chinese Academy of Sciences, IF = 11.446) Published, Associate Professor Cai Jingyong and Professor Shi Zhengrong are cooperative researchers.

In recent years, the comprehensive utilization of solar photovoltaic thermal heating (PV/T) has become a research hotspot in the field of solar energy due to high comprehensive utilization efficiency because it can be available at the same time. Reasonable integration of heat transfer mode is the cutting -edge topic of the direction of the direction while meeting the needs of users' electricity and heat needs. The first paper integrates passive phase transformation heat transfer (non -power consumption) and active phase transformation (with power consumption), designed and manufactured PV/T composite heat collectors/evaporator; and based on the composite heat collector /Evapoor, developed a photovoltaic-solar heat pump/heat pipe composite system; this composite system has two operating modes: main and passive operation mode, which can switch the operating mode according to real-time meteorological and user requirements. The experimental testing platform was established and the switching operation numerical model of the composite system was established to study the timing of the switching of the main and passive operation mode.

There are a lot of seasonal solar energy waste in the non -warming season for solar light thermal output. The second paper proposes two solar seasons to regulate the energy system, namely solar light thermal and photovoltaic integration, and solar light thermal and organic Langken cycle integration. Both systems can be regulated in the heating season to adjust solar energy for building heating, and make full use of the seasonal balance of solar energy in the non -warm season.

Associate Professor Zhang Tao and other studies in the fields of comprehensive utilization of solar photovoltaic light thermal use, construction energy conservation, heat pump and other fields. In the past two years, the first author and communications author published 7 papers in the Chinese Academy of Sciences. Except for the above two papers published on the Applied Energy There are 3 papers published in internationally renowned journals.

The above studies have been supported by the Shanghai Municipal Science and Technology Commission's key research projects, Shanghai -IV peak disciplines, and key innovation teams of local colleges and universities in Shanghai. (Correspondent: Fan Lida, Shanghai Electric Power University)
