Research To Dynamic Thermal Environment In The House About Central Heating Of Household-based Metering

With the innovation of heat supply in our country, the household heat metering of centralized heat supply is becoming more and more popular. Due to the operating characteristics of the system, the influence of heat transfer between household and intermittent heating should be considered calculating the heat load of house about household heat metering. So it is a focus for the calculation of heat load about heating house with household heat metering system. And the problem has a direct effect on heating supply results, investment economics and effective use of energy.The study measure is the numerical calculation of Computational Fluid Dynamic, the calculation tool is FLUENT. As calculation tool, the FLUENT has many advantages, for example, cheapness, rapidness, the ability of calculating idea conditions.The step of study is that: Firstly, this paper work over the measure of dynamic simulation considering single house as study object. Secondly, this paper engages steady calculation with three floor house. At last, this paper engage dynamic calculation and analysis of thermal comfort.
