85年3～5月,我们在法国进行能源审计的培训,同时对法国城市供热的情况也做了些了解并参观了巴黎和里尔二个城市的供热情况,现将法国供热情况简介如下。一、巴黎的城市供热巴黎市区有229万人口,加上近郊共有500万居民,市区占地约120平方公里,与北京三环路以内约140平方公里相近。巴黎的气候与上海地区相似。由于生活水平较高,室内温度一般恒定在19℃,低于17℃时开始供暖,所以供暖期约半年。巴黎城市的供热,一部份是集中供热,一
From March to May of the year 85, we conducted energy audit training in France. At the same time, we also learned about the situation of heating in French cities and visited the heating conditions in Paris and Lille cities. Now we report the situation of heating in France. The introduction is as follows. 1. Urban heat supply in Paris Paris has a population of 2.29 million, plus a total of 5 million residents in the suburbs. The urban area covers an area of 120 square kilometers, which is similar to the 140 square kilometers within the Beijing Third Ring Road. The climate in Paris is similar to that in Shanghai. Due to the high standard of living, the indoor temperature is generally constant at 19°C. Heating starts when the temperature is lower than 17°C, so the heating period is approximately six months. Part of the heating in Paris is concentrated heating.
