Abstract
It is found that the heat-supplied temperature in winter is generally too high by investigating the heat-supplied samples in China. The excessively high temperature increases energy consumption, aggravates environmental pollution, and leads to frequent occurrence of diseases such as respiratory disease, cardiovascular and cerebrovascular disease. Therefore, it is suggested that the heat-supplied temperature should be controlled under 20°C.
Highlights
According to the statistical yearbook of urban and rural construction 2017 released by the ministry of housing and urban-rural development, China's urban central heating area is 8.309 billion square meters, and heating energy consumption is equivalent to 164.2 million tons of standard coal, which will produce 432 million tons of carbon dioxide, 2.003 billion kilograms of sulfur dioxide, and 1.764 billion kilograms of nitrogen oxides
A large number of empirical studies on the relationship between winter heating and local pollution have been conducted in China's academic circles
Most scholars have concluded that winter heating is a result of close and positive correlation with local pollution
Summary
Since the winter of 2012, there has appeared severe haze weather in North China and Huang-Huai area. In terms of spatial distribution, Beijing, Tianjin, Hebei, Shanxi, Shandong and Henan are the areas with the most serious haze. According to the air quality status of 74 cities released by the ministry of environmental protection, the top 10 cities with the worst air quality from 2013 to 2017 are all in the northern heating areas. According to the statistical yearbook of urban and rural construction 2017 released by the ministry of housing and urban-rural development, China's urban central heating area is 8.309 billion square meters, and heating energy consumption is equivalent to 164.2 million tons of standard coal, which will produce 432 million tons of carbon dioxide, 2.003 billion kilograms of sulfur dioxide, and 1.764 billion kilograms of nitrogen oxides.
