Energy Simulation Analysis of Solar Wall Heating and Ventilation System in Severe Cold Region

In order to analyze the volume of air, which meet air supply conditions, per centiare Solar Wall panel can heated, also verify the feasibility and energy-conservation effect of Solar Wall System in severe cold region of China, a 3D model was established. The realizable k-ε model of the CFD Simulation Software FLUENT was applied to simulate conditions of different air supply velocity in the coldest month(January). The conclusion is that per centiare Solar Wall panel can heat 72.24 m³/h airflow, which can well meet the air supply condition during heating period in Shenyang. Therefore, Solar Wall Air System is available in heating air, which mixed by fresh air and recycling return air, and is significant in energy conservation. What is more, the air supply is within the capacity of the system, proving that the system is applicable and has significant energy-saving and low carbon effect in severe cold regions in China.
