Optimization of container house energy supply system for air source heat pump assisted with solar energy based on TRNSYS
Taking a container house in the northern mountains area of Beijing as the research object,the simulation model of the solar thermal-air source heat pump heating system was established by TRENSYS software,and the operating state in January was simulated and the operation results were analyzed.The results show that the room temperature does not meet the heating requirements,and the heating system cannot achieve off-grid operation.Then an optimization plan is proposed,replacing the solar thermal module with a solar photovoltaic solar thermal module,and the warm air blower terminal heating method is replaced by floor radiant heating.After optimization,the indoor temperature is greatly improved,maintaining around 20.0 ℃,that satisfies the heating requirements.The Room Temperature Fluctuation index was reduced from 78.0％to 12.5％.The total power consumption was reduced from 1 494.0 to 674.7 kW·h.The system's CO2 emission reduction increased from 108.75 to 325.27 kg,and the emission reduction increased by 198.9％.The photovoltaic solar thermal module has a power generation capacity of 713.0 kW·h,which meets the power consumption requirements of the room and theoretically realizes off-grid operation.The research results can provide a theoretical basis for the design of the energy supply system of container houses.
