长三角地区空气源热泵冬季频繁结霜应对措施OA

Countermeasures for frequent frosting of air-source heat pumps in the Yangtze River Delta re-gion are discussed from aspects including active de-frosting technologies,passive anti-frosting technolo-gies,improvement of standards,and policy incentives.Active defrosting technologies include ultrasonic de-frosting,reverse-cycle defrosting,and electric heating defrosting.Passive anti-frosting technologies include anti-frosting using superhydrophobic surfaces,anti-frosting using photothermal conversion materials,and anti-frosting using low-temperature thermal insula-tion materials.To address the high-humidity and low-temperature operating conditions in the Yangtze River Delta region,the contents of improving relevant standards are put forward.It is suggested that incentive policies should be introduced from the perspectives of financial subsidies,taxation,carbon market coordina-tion,market access and competition,and regional coor-dination and ecological co-construction.
