室内温度调控问题探究

Study on Indoor Temperature Control

以东北地区某典型房间为研究对象,对其室内温度调控进行了分析并提出以下问题:当室外温度为0℃,进水口流量为0.5 m^(3)/h时,求房间的空间温度分布;当室外温度为0℃,进水口流量在0.1~1变化时,求房间的动态温度分布。利用稳态导热微分方程,得到了温度关于空间的一维分布函数,建立了房间温度随空间与暖气流量的二维函数T(x,V),得出了暖气水流量和房间温度分布之间的关系,由此提出了暖气水流量控制方案,以期消耗最少的能源,满足用户对房间温度的要求。

Through taking a typical room in Northeast China as the research object,the study analyzes the indoor temperature control and proposes the problems.When the outdoor temperature is 0℃,and water intake flow is 0.5 m^(3)/h,spatial temperature distribution in the room is to be solved.When the outdoor temperature is 0℃,and water intake flow changes between 0.1 and 1 m3/h,dynamic temperature distribution of the room is solved.Through using steady-state differential equations of heat conduction,one-dimensional distribution function of temperature on space is got,two dimensional function T(x,V)of room temperature on space and gas flow is established,and relationship between heating water discharge and room temperature distribution is got.Therefore the study proposes the heating water discharge control scheme,to consume the least energy,and satisfy user’s demand on room temperature.
