摘要
为了对空气源热泵技术在长江流域因地制宜的应用提供理论依据,从研究结霜机理出发,同时考虑空气源热泵结霜与气象参数的关系,给出了基于空气干球温度与露点温度的空气源热泵结霜判据。应用该判据,对空气源热泵在长江流域9个城市的气候适宜性进行了研究,结果发现,空气源热泵的气候适宜性有绝对适宜性和相对适宜性之分,绝对适宜性是不同城市应用比较的基础,相对适宜性是单个城市应用的理论依据。并比较分析了本文研究结果与相关文献研究结果的异同之处。
To provide a theoretical basis of air-source heat pump application for the local conditions,studies frosting mechanism on cold surfaces,takes into consideration the relationship between frosting of air-source heat pump and climate parameters at the same time,and gets the frosting criterion of air-source heat pump based on air dry-bulb temperature and dew-point temperature.By means of the criterion,researches the climate suitability of air-source heat pump in 9 cities in the area.The results show that the climate suitability of air-source heat pump is divided into absolute climate suitability and relative climate suitability,with the former being used to compare different cities and the latter taken as the theoretical basis of application in a specific city.Compares and analyses the similarities and differences of the authors＇ findings and other related references.
