摘要:

近年来,长江流域居住建筑供暖的呼声越来越高,相关供暖技术越来越受到人们重视。从长江流域的气候特点、建筑物围护结构和供暖特点出发,针对居住建筑,综合分析了常用的单一热源热泵供暖方式、复合热源热泵供暖方式和供暖末端形式。认为分户式空气源热泵供暖是解决长江流域住宅供暖问题的快捷方式,小区域性的能源塔热泵供暖是重要途径,多热源复合供暖是发展方向。城镇应以节能高效的小区域集中供暖为主,分户供暖为辅;乡村应因地制宜地采用清洁能源供暖技术,充分利用长江流域的水源和地源的优势。应大力发展复合热源供暖方式,在提高节能性和供热效率的同时提升其经济性。辐射式散热末端具有优异的舒适性和节能性,是一种比较理想的供暖末端形式。建筑节能技术应与供暖技术共同发展。

Abstract:

In recent years, the demand for heating of residential buildings in the Yangtze River Basin has been increasing, and the related heating technology has been paid more attention. Based on the climatic characteristics, building envelopes and heating characteristics of the Yangtze River Basin and focused on residential buildings, comprehensively analyses the common single heat source heat pump heating mode, the composite heat source heat pump heating mode and heating terminal forms. Considers that the household air-source heat pump heating is a shortcut to solve the residential heating problem in the Yangtze River Basin, the energy tower heat pump is an important way of heating in small region, and the multiple heat source compound heating is the development direction. In cities and towns, energy saving and efficient small district central heating should be the main heating way, supplemented by household heating. In rural areas, clean energy heating technology should be adopted in accordance with local conditions to make full use of the water and ground sources in the Yangtze River Basin. It is necessary to develop the composite heat source heating system to improve its energy saving, heating efficiency and economical efficiency. The radiant terminal has excellent comfort and energy saving, which is a suitable and perfect heating terminal form. The building energy saving technology should be developed together with the heating technology.
