Research progress on defrosting technology of air source heat pump
The research progress on defrosting technology of air source heat pump at home and abroad is summarized.Aiming at the current demand for fast defrosting and de-frosting with heating capacity,as well as the booming development of phase change energy storage technology in recent years,the improvement measures of conventional de-frosting methods are introduced,as well as current research hotspots,such as gas supple-ment defrosting,non-stop defrosting,ultrasonic defrosting and intelligent defrosting and other technologies.The research shows that researchers have not stopped improving all kinds of conventional defrosting technologies,and it is still difficult to be well solved the contradiction between the improvement of defrosting efficiency and the increase of system complexity,technical requirements,cost and energy consumption of air source heat pump defrosting while taking indoor comfort into consideration.The fast defrosting and non-stop defrosting while heating are the future development directions of the defrosting technology of air source heat pump.
