摘要(Abstract):

从除霜方式和除霜系统优化、霜层形成机理、抑制结霜技术与结霜/除霜工况下机组的动态特性等4个方面对空气源热泵除霜问题的研究现状进行了评述,提出存在的问题并展望了今后研究的发展。
Due to the low temperature and high humidity outdoors in winter,frost will form and accumulate undesirably on the surface of outdoor heat exchanger,which will degrade the performance of air source heat pump(ASHP).The research on air source heat pump defrosting at home and abroad was reviewed from four aspects: optimization of defrosting system,mechanism?of frost formation,measures to retard frost and dynamic characteristics of system under frosting/defrosting conditions.The development prospect of ASHP was also carried out.
