Abstract
In order to solve the problems of air source heat pump heating system （ASHP system） in severe cold region, such as substandard heating effect, low efficiency and high energy consumption, it is necessary to reform and optimize the energy systems. The research object was the ASHP system of an office building in severe cold region. The system design and operation data were investigated on site, the heating effect of the ASHP system was analyzed, and an optimization plan for renovation was proposed. The models of solar photovoltaic air source heat pump coupled heating system （PV-ASHP system）, solar thermal air source heat pump coupled heating system （SC-ASHP system）, and solar photovoltaic thermal air source heat pump coupled heating system （PV/T-ASHP system） were constructed by TRNSYS software to study the feasibility of the transformation scheme. The results showed that compared with the heating system before the transformation, the Ccop of the SC-ASHP system and the PV/T-ASHP system can be increased to 7.10 and 6.57. The energy consumption of the PV-ASHP system and the PV/T-ASHP system is reduced by 50%, and the solar energy utilization rate of the PV/T-ASHP system is the highest, reaching 61.5%.
