Paper Title:
Study on Change Regularity of Air Temperature Underground Tunnel Based on Intermittent Operating of Heat Pump
  Abstract

In this paper, based on the analysis of strata soil temperature variation, the DeST software is used to simulate changes of outdoor air parameters under typical meteorological year in Jinan. One-dimensional unsteady state soil air heat transfer model is regarded as the research object, this paper theoretically studies export air temperature change rules for the whole year under tunnel intermittent running condition. The results show that the tunnel plays a preheating role for outdoor air in winter and the cold role in summer, which provides a good cold、heat source conditions for the application of air source system based on the tunnel wind, especially the most hot and cold day throughout the year, the system has a remarkable effect.
