高大空间分层供暖室内气流的数值模拟研究

Numerical Simulation Research on Air-distribution in A Stratified Heating Large Space

以重庆地区某高大机械加工厂房分层空调为对象,建立厂房分层供暖设计方案下的计算模型,分析了送风射流特性,并对分层供暖气流分布特性和送风机理进行详细分析,结果表明分层供暖能使热射流充分作用于供暖区,抑制大空间上下部间的热对流,但并不能产生很大的节能效益。

Choosing a large machine workshop in Chongqing area as an object, the computational models under the stratified air conditioning design schemes were built, and the properties of the air supply jet were analyzed. The distribution characteristic of airflow was described, as well as the wind supply mechanism under the stratified air conditioning. The research results show that stratified heating can make a full use in the heating area and inhibit thermal convection between the upper and lower in large space, but it can＇t produce a huge benefit of energy conservation.
