一、概述随着我国建筑事业的发展,改革我国采暖建筑外围护结构的形式,加大热阻,节省采暖建筑的能耗,是一个刻不容缓的问题。哈尔滨建筑工程学院的资料已就哈尔滨地区采暖建筑节能和墙体的改革进行了较详细的探讨,同时还推荐了哈尔滨地区采暖建筑的最优墙体结构形式。本文进一步探讨我国不同室外采暖温度地区,与墙体结构形式相适应的经济热阻这样一个问题,供大家在采暖建筑的设计中参考。二、有关公式的推导墙体热阻增加,一次投资增多,但采暖耗能费用减少,同时采暧的运行及设备费用也减少。经济热阻主要取决于两个因素:
I. Overview With the development of China’s construction industry, reforming the form of external thermal protection structures in China’s heating buildings, increasing thermal resistance, and saving energy consumption in heating buildings is a matter of no delay. The Harbin Institute of Civil Engineering and Architecture has conducted detailed discussions on the energy saving and wall reform of heating buildings in the Harbin area, and also recommended the optimal wall structure for heating buildings in the Harbin area. This paper further explores the issue of economic thermal resistance in different areas of the country’s outdoor heating temperature and in accordance with the structure of the wall structure, for reference in the design of heating buildings. 2. With regard to the derivation of the formula, the thermal resistance of the wall increases. Once the investment is increased, the cost of heating and energy consumption is reduced. At the same time, the operation and equipment costs of the mining are also reduced. Economic thermal resistance mainly depends on two factors:
