The global average temperature has broken records several times this summer. The high temperature is unbearable, and the centralized cooling has once again become a hot topic in technology. Despite the weather, the temperature is still high. The reporter learned that in Suzhou high-speed rail New City and other places, has achieved "centralized energy supply", users do not need to install their own air conditioning host can achieve summer cooling, winter heating. How is centralized energy supply achieved? Is it possible to enter ordinary people's homes in the future? Reporters visited.

The 'vanishing Air conditioner'

In an office building in Suzhou high-speed Rail New City, the reporter felt a burst of cool, but this cold feeling did not come from the user's self-built air conditioning, but from the centralized cooling. In the winter, it can be centrally heated, and the centralized energy supply of warm winter and cool summer has become a reality.

Here, centralized energy supply is expected to enter the homes of ordinary people

At present, the application scenarios of centralized energy supply in Jiangsu are mainly CBD, commercial core areas, emerging industrial parks, centralized office areas, etc. In the future, will centralized energy supply enter the homes of ordinary people?

Large-scale promotion of the application of centralized energy supply needs the overall planning support of the government. Hao Jianjun told reporters that the construction cycle of the centralized energy supply system has a long time span, and the infrastructure such as energy station housing and energy supply pipe network has a large investment. Hence the need for government leadership and planning first. At the same time, he believes that the scale of the centralized energy supply system should be appropriate, taking into account that there is a certain scale effect, to achieve the economy of infrastructure investment, but also to consider that if the large-scale planning, the production cycle is too long, the early investment allocation and the "big horse car" network loss may bring a heavy burden to the project. Therefore, it is necessary to take into account the economy under the premise of reliable and advanced technology. Through stable and reliable energy supply guarantee and high energy utilization efficiency, the project can achieve a comprehensive balance of energy conservation and emission reduction, high comfort and economy.

From point to point, centralized energy supply can first "gain a foothold" in the business district with large population density. Huang Yifeng believes that centralized energy supply needs to strengthen planning and guidance, implement the layout of energy stations in the concentrated areas of new buildings such as business districts, parks and residential buildings with large population density and high building density, integrate the unified planning of power, water, communication, gas, steam and energy supply pipelines, and build an efficient and stable centralized energy supply system.

He believes that for the power price of energy stations, it is recommended to implement preferential pricing for the cooling and heating operation of comprehensive energy stations using renewable energy, and explore the possibility of implementing some residential electricity prices in proportion to the service of public and residential mixed buildings. At the same time, for residential areas that adopt centralized energy supply, it is recommended to properly adjust the construction standards of power supply and distribution facilities, reduce the power allocation per unit area, further reduce the development cost, avoid resource waste, and release the grid margin.

"' Overall innovation ', overall resource conditions, energy demand, environmental protection and economic benefits, scientific formulation of special plans to achieve regional energy system investment, construction, operation of the system and model innovation; "Scientific energy use", according to the user load characteristics, reasonably determine the scale, optimize the system configuration, according to the grade corresponding, temperature interface requirements, to achieve energy integration, cascade and recycling; "Reliable and reasonable", from the stable reliability of energy supply, to seek the rational and balance of system technology and economy. 'Low carbon environmental protection', that is, to create a green eco-city of a new high-speed rail city, fully adopt energy-saving technologies, low carbon emissions, and minimize the impact of the energy system on the environment." Gu Guodong said.
