| 摘 要： | 针对寒冷地区普通空气源热泵在该地区冬季使用时制热量衰减、室外极易结霜等缺点，提出以地道风作为空气源热泵的低位热源。以济南市为例，采用DeST软件对寒冷地区冬季气象条件进行了模拟分析，并根据换热模型计算得出了埋深6m的地道出口空气温湿度的变化值。结果表明，与普通空气源热泵相比，基于地道风的空气源热泵不仅可以充分利用土壤层储存的自然热量，还可以有效地提高热泵的性能系数，避免热泵的结霜，节能效果显著。

| Abstract: | According to shortcomings of conventional air source heat pump applying in cold regions,heating capacity decrease and the evaporator frosting,this paper presents a new heat pump system in which underground tunnel air is served as air source.The ambient air temperature and humidity in Jinan are simulated adopting DeST soft.Air temperature and humidity at the outlet of tunnel buried 6m below ground are calculated on the basis of the heat exchange models of earth-to-air.The calculated results show that air sou... |
