室内自然对流散热的直膨式空气源热泵研究进展
Research progress on air source heat pump with direct expansion indoor natural convection heat dissipation
摘要
Abstract
Under the promotion of the clean heating policy of"coal to electricity",air source heat pump heating technology has developed rapidly.On the basis of introducing the research on traditional hot water and hot air source heat pump heating technology,this paper focuses on analyzing the principle,terminal development types,and structural characteristics of the new direct expansion air source heat pump heating technology,such as condensation direct heat dissipation,condensation indirect heat dissipation,and condensation heat storage heat dissipation terminal.A comprehensive evaluation of its application fields and actual operating effects is also conducted.The direct expansion air source heat pump heating with natural convection heat dissipation has no intermediate heat medium secondary heat exchange,fast heating speed,effectively improves indoor thermal comfort,and enhances energy efficiency.In addition,the future development direction of air source heat pump heating technology is discussed,which will be further improved from the aspects of end of pipe high efficiency and serialization,low global warming potential(GWP)working fluid,rational operation and regulation,multifunctional heat pump,and compatibility with residential buildings,providing reference for promoting and expanding its engineering applications.关键词
