What is the division of heating areas in China?
The main reason for the "north-south difference" in heating lies in the demarcation of heating in Qinling and Huaihe rivers formulated at the beginning of liberation. But at that time, this line was formulated based on the consideration of the level of economic development, not the actual need. The south without heating is colder than the north, and even many northerners can't stand the winter in the south. Once there is snow and ice, the temperature in the south will drop below zero, which makes people even more "unbearable".
It is obviously out of date to continue to decide whether to provide heating according to the north-south dividing line drawn a hundred years ago. In fact, the call for central heating in South China has been going on for many years, but every time it is much cry and little rain, the relevant proposal has not been recognized by the decision-making level so far. The basis of opposing each other is mainly huge energy consumption.
Extended data:
1, the central heating mode in China follows the Soviet Union.
The central heating system in China began in 1950s. Referring to the model of the Soviet Union at that time, the residential boiler heating system was initially established. At that time, the Soviet Union defined the outdoor temperature below 5 degrees Celsius as winter, while China stipulated that only areas where the daily average temperature does not exceed 5 degrees Celsius and the number of days exceeds 90 days can provide central heating.
It mainly includes North China, Northeast China and Northwest China. Throughout the world's winter heating modes, neither Russia with central heating (that is, the former Soviet Union) nor European countries with household heating have divided heating areas by geographical boundaries like China.
2. The division of the North-South boundary is unscientific.
In 1950s, China demarcated the north as a central heating area with the Qinling Mountains and Huaihe River as the boundary, while the south did not provide central heating, that is, the north-south heating hotline. However, according to the latest statistics, the average winter temperature in many areas in the "South" often breaks the data record of "no more than 5 degrees Celsius", which is a reference for central heating.
"No more than 5 degrees Celsius" is only based on the human body's feeling of temperature, and does not consider other related factors such as humidity and wind speed. Therefore, it is unreasonable for the surrounding areas near the dividing line to decide whether to provide central heating according to the north-south dividing line.
