Study On A 22kW Compound Energy System Combined With Air Source Heat Pump And Solar Energy

Energy resourcesand circumstance have turn intoa universal concern of society.Because of the unique preponderance of energy saving and environmental protection,the heating and heating equipment combined with solar energy and heat pump has been paid much attention by the scholars at home and abroad.Solar water heaters are becoming increasinglypopular,but solar water heaters are vulnerable to climate and weather,and cannot operate stably all day long.As an efficient energy-saving device,air source heat pump water heater has become increasingly important because of its pollution-free,high efficiency,saving energy and free from the influence of light.These two systems are combined to form a solar assisted air source heat pump system,the maximum possible can overcome the weakness of both and give good play to the advantages of both,so as to ensure that all day long efficient preparation of domestic hot-water and indoor heating requirements.This paper reviews the solar water heater,the air collector of solar,and the merits and drawbacks of the working principle and development status of the heat pump and heat exchanger,solar energy has pointed out other incomparable advantages,and points out that the solar system encountered problems in practical application andmerits and drawbacks,and puts forward the best solution for the solar energy.In this paper,the analytic study of solar collector system,regenerative system and the heat pump of air source on indoor supply heating efficiency and multi energy supply of system combination model are analyzed.Through the new control strategy,the fusion of solar energy and the heat pump of air source is utilized,and the indoor air conditioning and heating requirements are realized with higher system comprehensive utilization ratio and system cycle performance coefficient.United with the needs of the topic,a series of the water heat collector of solar with air source heat pump experiments and an air collector of solarwith air source heat pump experiment were carried out.The data of heating and non-heating time proportion in winter were collected.In combination with the results of winter climate conditions and experimental analysis in Wuhan region binding mode of heat collector,water of solar air collector and heat pump are discussed scientific,detailed,and develop the most with Wuhan weather and meet the requirements of intelligent energy efficient work mode selection,and the typical working conditions were calculated.This experiment,with the help of experimental platform and theoretical analysis,combines solar energy with heat pump well,and can learn from each other to achieve the effect of indoor heating at low temperature.
