建筑物热力入口热量供需平衡调节方法

Regulation Method of Heat Supply and Demand Balance at Building Heat Entrance

采暖系统水平失调是建筑供热的常见现象,从而导致供热系统供热量往往与建筑热负荷不配备,因此如何使供热量按需调节对建筑采暖节能降耗具有至关重要的作用。为解决该问题,本文针对散热器采暖系统,提出了基于能量平衡法的供热系统热量调节方法,并在一个办公建筑中实现了工程应用,分析了采暖系统常数的实验获取方法,实验研究了能量平衡法对建筑室内平均温度控制的效果,并与利用入口温度调节时的室内平均温度进行了比较。结果表明,基于能量平衡法可以稳定地控制建筑室内平均温度,与采用入口温度调节的方法相比,基于能量平衡法调节供热量时,建筑室内平均温度的波动较小。

The imbalance of heating system is a common phenomenon of building heating,thus the supply of heating system often doesn’t match the building heating load,therefore,how to adjust the heat supply of heating system according to the building demand is of vital importance to save building heating energy consumption.In order to solve the problem,in this paper,the heat regulation method of heat supply system based on energy balance method is proposed,and the engineering application is realized in an office building,and the experimental method of obtaining the heating system constant is analyzed.The effect of the energy balance method on the average temperature control in the building was studied experimentally and compared with the average temperature in the building when the inlet temperature was adjusted.The results show that the average temperature in the building can be controlled stably based on the energy balance method.Compared with the method using the entrance temperature regulation,the wave of average temperature in the building is less when the energy balance method is used to regulate the heat supply.
