空气源热泵低温适应性研究的现状及进展

随着改革开放的发展、人们生活水平的提高，许多传统供暖地区的居民开始有夏季制冷的要求，而且这些地区传统的以燃煤为基础的供暖模式所带来的负面影响越来越不能适应社会可持续发展的要求。空气源热泵因其特殊的优点而在长江中下游以南地区备受重视，但是传统的空气源热泵要想成功应用下地北方寒冷地区还有许多问题有待进一步解决。文章分析了空气源热泵系统在寒冷地区使用时需要解决的一些问题，以及国内外为解决这些问题所做的一些工作，对于更好地促进这空气源热泵技术的发展具有积极的意义。

State of knowledge and current challenges in the ASHP developed for the cold areas

With the development of national economy and improvement in people's living standard, spacing cooling is gradually populated among people living in the cold areas; what's more, the conventional spacing heating method based on coal|fired boilers can't meet with the policy of sustainable development. Of all the available heating and cooling methods, ASHP (Air Source Heating Pump) is the optimal method for its self|evident virtues, however the conventional ASHP can't run in the cold areas and a spare heating source is needed when the ambient temperature is very low, and thus initial cost is soaring and unbearable considering the low rate of utilization. In this paper the author analyzed several problems that prevent the ASHP to be used in the cold areas, relevant researches round the world are reviewed, which is very beneficent to the perfection of the ASHP.
