As winter is approaching, many places in the north have already provided heating or have begun trial heating, which has also heated up the topic of "southern heating". The pace of southern heating is firmly moving forward, including Shanghai, Hefei, Wuhan, and Chongqing In many areas, many communities have joined the ranks of central heating.
​Recently
, some media disclosed a statistical data: In 2019, the sales of household radiators increased by 430% year-on-year, and the "main force" of sales growth is Shanghai, Nanjing, Wuhan and other southern cities. At the same time, Xu Wei, dean of the Institute of Building Environment and Energy of the China Construction Research Institute, also introduced to the media: "After a rough calculation, the total heating market in the south may be 400 billion to 500 billion in the next ten years. Increase the scale by 40 billion."

Over the years, the Qinling-Huaihe line has gradually become the geographical dividing line between the north and the south in my country. In the 1950s, it became the dividing line between the north and the south for collective heating. The heating modes of the two sides are very different.

When winter comes, the problem of heating in the south becomes more and more prominent. Many cities start to take the heating system into consideration when building new communities, which shows that the problem of heating has become very urgent and has become a basic need of many residents. Especially in the recent period, affected by the cold wave disaster, the temperature in the southern region has changed greatly. In some cities, the government has implemented a plan to provide heating for the winter.
Many urban residents in southern my country use air conditioners and electric heaters to survive the cold winter, which seriously wastes power resources, increases energy consumption, and increases the burden on residents. There are many hidden dangers in terms of safety.
Why does the south not adopt large-scale heating like the north? Some experts in the industry believe that there are some practical difficulties in the demand for central heating in the south. For example, there is no special heating plan in urban planning in the vast southern region, and the investment in heating infrastructure is huge, and the economic burden on the government and residents is heavy.

Should there be heating in the south? As early as the heating season in 2015, the Ministry of Housing and Urban-Rural Development responded by advocating the scientific selection of appropriate heating methods in the "Southern Region" and adopting decentralized and local heating methods to meet individual heating needs. The "Southern Region" mainly refers to the Yangtze River Basin, which is characterized by hot summer and cold winter, involving 14 provinces (municipalities directly under the Central Government) and an urban population of about 150 million. The "southern region" is humid and cold in winter, and when the outdoor temperature is lower than 5°C, people feel a strong sense of discomfort. Heating in winter in the "Southern Region" is a natural demand after the improvement of living standards. What kind of heating method is suitable needs to be solved as a whole.
The particularity of the principle of the air source heat pump heating system has become the first choice of heating equipment for "coal to electricity", and it is also the first choice for many families to choose heating equipment. For buildings with heating and cooling requirements, air energy heat pumps are not only convenient and easy to install, but also require less installation workload than traditional engineering systems, and it is relatively easy to change the installation. During the operation of the whole heating system, the unit can reach the standard of zero pollution and zero discharge, and this feature is in line with the general trend of energy saving and environmental protection. At the same time, the air source heat pump can choose various heating ends without re-construction. The temperature balance in the heating area and intelligent control can meet the user's pursuit of high-quality life for comfortable heating.

After years of technical accumulation and large-scale engineering practice in northern heating, the air source heat pump technology has been continuously enriched and improved. Technologies such as air source heat pump cooling and heating combined supply system and triple supply system have injected fresh blood into the market, opened up a new market pattern, and become a hot spot for heating in the south.
With the development of science and technology, air source heat pumps or traditional heating methods are gradually combined with the Internet. In the future, it is very likely that the heating system will be connected with other intelligent equipment to form an intelligent community based on the Internet of Things management system. Intelligent buildings, etc., adopt scientific means to control the heating system. I believe that with the express train of science and technology, the air source heat pump with high efficiency, energy saving and environmental protection will become a popular heating method for heating in the north and south.
