Research and design of concentrating photovoltaic coupled heat pump cogeneration system

In this paper, the research on building cogeneration system based on concentrating photovoltaic coupled heat pump complementarity is carried out, and the cogeneration system platform is built. The energy transfer model and optimal combination of concentrating photovoltaic photothermal system, coupled heat pump heating, hot water supply system, heat storage system and other system components are studied, the operation mechanism of cogeneration system is analyzed, and experimental tests are carried out. Study the steady-state operation parameters that maintain the maximum comprehensive utilization rate under different working conditions under high cold and high altitude conditions and the system operation regulation strategies under different demand conditions, so as to improve the comprehensive energy utilization rate, reduce building energy consumption, provide technical support for building energy conservation in Tibet, and further provide new development ideas for realizing "carbon peak" and "carbon neutralization" in Tibet.
