室内低温热水地板辐射供暖系统的节能分析

Analyses on Energy Saving in Interior Low-temperature Hot Water Radiant Floor Heating System

本文阐述了低温热水地板辐射采暖分户热计量系统是一种易控、易调、节能的采暖系统,讨论了地板辐射供暖方式与其他方式在房间内人体热舒适方面的差异,并通过对其综合节能效果的考察,分析了地板辐射供暖系统不稳定供暖过程的数学模型,用数值计算的方法分析了间歇供暖条件下,达到室内要求温度所需的预热量与预热时间的关系。

The low tewperature hot water radiant floor heating systen equipped with household-based heat metering is one of the systems easy to control and efficient to utilize energy.In this paper,radiant floor heating system is discussed by comparing with other heating ways in the thermal comfort.Based on general energy saving analyses,one mathematical model of radiant floor heating syslem instability is established,and with the help of numerical simulation,the relation of the pre-warm space with the pro-warn-up time is determined on the indoor temperature needs of intermittent heating.
