通过对夏热冬冷地区的地理位置、内部气候进行说明与分析,对现有采暖方式及设施进行综述,分析出现有采暖方式的优缺点;结合目前的节能趋势和市场要求,提出夏热冬冷地区采暖方式发展的趋势与走向。近年来冬季中国南方频繁出现极端天气,主要表现在以下几个方面:一是平均气温明显偏低,最冷月平均气温0℃~10℃,甚至部分地区日最低气温破历史极值;二是降温幅度大,低温持续时间长;三是雨雪多、湿冷特征明显,月平均相对湿度在80%左右。因此南方城市对集中供暖的呼声愈加高涨,特别是长江流域夏热冬冷地区,包
Through the description and analysis of the geographical location and internal climate of the hot summer and cold winter area, the current heating methods and facilities are summarized and the advantages and disadvantages of the existing heating methods are analyzed. Based on the current energy saving trends and market requirements, Trend and Trend of Heating System in Cold Area. In recent years, extreme winter weather in southern China frequently occurs, mainly in the following aspects: First, the average temperature is obviously low, the coldest month average temperature is 0 ℃ ~ 10 ℃, and even the daily minimum temperature in some areas is broken the historical extreme; Second, Large temperature range, low temperature long duration; Third, more snow and rain, wet and cold characteristics are obvious, the average monthly relative humidity of about 80%. Therefore, the voice of central cities in southern China is getting louder and louder, especially in hot summer and cold winter areas in the Yangtze River Basin.
