Optimization for Solar-thermal Water Source Heat Pump Hybrid Heating System Based on TRNSYS
In view of the inadequacies of solar heating technology and heat pump heating technology,a solar-thermal water source heat pump composite heating system was designed.Taking a project in the Tibet Xigaze area as the research object,TRNSYS simulation software was used to establish a solar-thermal water source heat pump composite heating system model,conducting simulation analysis of the running characteristics of the heating system and analyzing the economy of the system.Then,the Hooke-Jeeves optimization algorithm was used to optimize the key parameters of the heating system.The results show that the solar-thermal water source heat pump composite heating system in Tibet can operate efficiently and stably,realizing the cascading utilization of solar energy from high temperature to low temperature.During the heating season,the system's average coefficient of performance reaches 4.43.Compared with electric boiler heating,the composite heating system has a higher economy,and the static payback period is 5.3 years.After optimization,energy consumption is reduced,leading to a 7.9％enhancement in the system's average coefficient of performance during the heating season.
