Abstract


Authentic wind one of the ways is to make use of renewable energy , authentic wind building air-conditioning and ventilation energy consumption savings this topic is in promoting the development and utilization of new energy and renewable energy situation to re-submit its application prospects very wide. In this paper, on the basis of the analysis of authentic wind down ( liters) warm Research , authentic wind ventilation and air conditioning prospects . First analysis and calculating the distribution characteristics of the soil temperature , including the initial soil temperature, the the formation temperature change after use . Then coupling the fourth class of boundary conditions that the boundary conditions for the introduction of dynamic heat transfer numerical model of underground engineering the authentic air can be more realistic under actual reaction conditions and rock dynamic coupling between the heat transfer process , and effectively avoid convective heat transfer coefficient in the actual process is not a constant problem . The main work of this paper are : to establish the mathematical model of heat transfer between the air and the wall , in certain non-isothermal and non- heat flux boundary conditions , the calculation program , carried out of the air and the the authentic heat exchanger process simulation analysis ; simulation systematic analysis of various factors on authentic wind down ( liters) warm by authentic air heat exchanger of the outdoor air ; calculated under different conditions, the final temperature for the application of of authentic wind in ventilation and air conditioning provides a theoretical basis .
