为分析供热系统安装散热器温控阀后的流量变化及影响因素,建立建筑层次的计量供热系统动态模型,并结合算例进行模拟。结果表明,在供热系统供水温度一定时,流量变化的主要影响因素为太阳辐射、外温及用户行为。北京某一典型日的计算结果表明,当楼内所有用户对温控阀均不进行调节时,楼栋相对流量在1d内的降幅约30%;当50%的用户按作息调节阀门时,流量降幅范围约60%～90%。
In order to analyze the change of flow rate and its influencing factors after the radiator thermostat valve is installed in the heat supply system, a dynamic model of building heating system is established and simulated with the example. The results show that the main factors that affect the flow rate change are solar radiation, external temperature and user behavior when the temperature of water supply in the heating system is constant. The calculation results of a typical day in Beijing show that when all the users in the building do not regulate the temperature control valve, the relative flow rate of the building decreases about 30% within 1d. When 50% of the users adjust the valve according to the operation and rest, the flow rate Decline range of about 60% to 90%.
