Experimental Research On Multi-source Solar Energy And Air Source Heat Pump System With Serpentine Tube Energy Storage Exchangers

Multi-source solar energy and air source heat pump system with serpentine tube energy storage exchanges combines the advantages of air source heat pump, solar energy utilization technology and energy storage technology, it is a new high-efficiency heat pump system. The system uses the cleaning energy, such as air source energy and solar energy, and they both complement each other.. In the meantime, the new system is going to improve some problems such as air source heat pump operating inefficiently and even not running; the new system uses energy storage material Rt6for storage in the night and the evening low power, which reaches the "peak shifting and valley filling" purpose and relieves the problems of power shortage, which saves operation cost.The system can be operated in different patterns in light of the demands of consumers or the climate conditions by switching the angle valve to change the direction of refrigerant. In total, it has more than10different running modes. The adjustment is flexible, functions are wide, it can be run throughout the year.Through the calculation and selection, we build the experimental platform and do a lot of experiments. We observe and analyze the operating rules under the effect of different temperature, pressure and the volume of serpentine tube energy storage exchangers. Then, we make the numerical simulation using FLUENT and compares with the experimental data, which verifies the reliability of the system.Experimental results show that the system is efficient, safe, stable and reliable.This project is sponsored by science and technology support program of Jiangxi province (Project No.:20112BBE50031).
