Is there central heating in the south? What are the ways?

The first choice for central heating in the south is medium-fired heating. In response to the increasingly urgent winter heating needs of non-traditional heating areas in the south, the China Gas Heating Project is a comprehensive solution for distributed central heating innovatively proposed and promoted by China Gas, and is a smart central heating system using the concept of distributed energy, referred to as China Gas Heating House.

Relying on China Gas's rich experience in comprehensive energy transmission and distribution and management, China Gas Heating Home Project has innovatively developed a high-efficiency and energy-saving heat source system, an intelligent heating transmission and distribution system, and an indoor intelligent temperature control system, and carried out efficient heat energy configuration through the intelligent heating cloud management system, and provided users with high-quality heating services with comfortable room temperature, economical use, safety and reliability, and long-term stability with the support of the intelligent CRM customer service system.

The project is an urban public utility, which will greatly improve the happiness index of local urban residents and the quality of the working environment.

In order to provide heating in the south, the principle of several aspects should be adhered to.

First, the principle of environmental protection should be adhered to. Coal-fired heating has become one of the "culprits" of smog in the north, and even "coal-to-gas" heating has a certain amount of pollution. Therefore, no matter what form of heating, it should be based on the premise of clean heating, energy conservation and emission reduction.

Second, the heating in the south should learn from the heating experience of the north for decades, but also cannot copy the northern model. The terrain of the south is complex, mainly mountainous and hilly terrain, the difficulty and cost of construction are relatively high, and the early stage of urban construction in the south did not consider heating, and there was no laying of heating pipe network, and now it is necessary to lay it comprehensively, which is both wasteful and unrealistic. At the same time, the heating time in most areas in the south is basically less than 2 months, the equipment utilization rate is low, and the depreciation and labor costs also increase.

In addition, heat loss from pipes is also a problem, and the pipeline transportation process is the main way to lose heat from heating. Therefore, we should give full play to the role of the market, do not subsidize or subsidize less, and effectively solve the pain points of southern residents in winter by improving the marketization level of the heating industry; Adopt more advanced heating technology, do not engage in complex heating system infrastructure, improve equipment utilization, reduce pipeline heat loss, reduce operation and maintenance costs, etc.

Third, the heating in the south should adhere to the principle of inclusiveness. At present, the cost of decentralized heating for southern residents, including floor heating, gas wall-hung boilers, etc., is almost 6,000 yuan and 8,000 yuan for a heating season. Scientific and reasonable measures should be taken to truly make residents affordable and comfortable, and enjoy clean and intelligent moderate central heating.

At this year's two sessions, the topic of heating in the south was mentioned again, and many representatives and members called for it to be started as soon as possible. Within a week after the meeting, Chengdu, Sichuan Province solicited heating needs from all residents in the city, and only 30% of the residents in each community or building needed to agree to build central heating. The charging standard is 230 yuan square meters, and the use fee is 10 yuan per month.

Compared to central heating in the north, the cost is a bit higher.

In fact, as early as a few years ago, some residents in the south called for central heating. However, the buildings in the south are not insulated, and the houses are more scattered, which is not suitable for the central heating model of the north. Otherwise, not to mention the cost of building a pipe network, the smog disaster in the north is also a lesson from the past.

Therefore, if the south wants to provide heating, it can only explore distributed central heating with local areas as a unit. For example, district central heating does not need to use large-scale centralized heat sources, and the laying of pipe networks is also simpler.

Air energy heat pump is a device that only needs a small amount of electrical energy to drive, mainly absorbing heat in the air to make heat, and the energy-saving effect is about three times that of electric heating. There is no harmful gas emission, and there will be no adverse effects on the environment, which is very suitable for the environment in the south.

Air energy heat pumps have household and commercial machines, household heating can be divided into households, and commercial households can be used for district central heating. From the point of view of investment costs, the cost of central heating will be lower, but sub-household heating also has its advantages, that is, the temperature can be freely controlled, open when you want, turn off when you want, and the temperature of each room can be adjusted freely.

Of course, at present, it is still difficult for the south to implement central heating, after all, the fact that the building is not insulated cannot be changed, which will be much higher for families who want to heat. Therefore, only some households with good conditions will consider self-heating or central heating. Although the investment cost of self-heating is higher, it is convenient and can control the temperature freely.

If it is central heating, even if no one is at home for ten and a half days, the heating fee will have to be paid.

No, the implementation of central heating in the south is very uneconomical and will cause huge energy consumption.

Will central heating be implemented in the south? The possibility of central heating is very small, this is because in the south of winter, the temperature is not very low, there is no need for heating, especially in Fujian and Guangdong, the average temperature in winter is more than ten degrees. However, it is also possible to provide central heating in slices or provinces, and central heating in areas with an average temperature below zero degrees in winter.

Of course not, because it is cold in the south for so many months, there is no need to do central heating, which is too expensive.

I don't think so, because it's not necessary, and it costs a lot of money.

The person in charge of the urban construction department of some cities believes that the annual heating cycle in the south is short, the utilization rate of central heating facilities is low, and the unified central heating mode in the north is not suitable for the south. The reporter randomly interviewed two heating pipes in Hefei City that have been in the community for about 10 years, and found that about 30% of the owners still have not turned on the heating.

It can be seen that how to provide central heating in the south is also facing its own unique regional problems. What's more, the south is also a vast regional concept, and the temperature difference in winter is obvious, which undoubtedly creates different opinions for the consensus on heating.

China's central heating system, which is modeled after the Soviet Union, is bounded by the Qinling Mountains and the Huai River, and delineates the north-south heating line, lacking the flexibility to deal with climate change or extreme weather. In addition, the "energy threat theory" advocated and the extremely high cost of renovating the heating infrastructure in southern cities, and the reluctance of developers to invest, ultimately led to the delay in heating supply in the south.

The reasons for the cold winters in the south are:

1. The air humidity in the south is high, and the clothes are very humid, which is not warm when attached to the body, which is equivalent to not wearing it. But the cold in the north can be solved by wearing more clothes, the main thing is the problem of humidity, plus the warmth measures in the south are not very good, the walls are thin, and there is no heating.

2. In the south, the wet wind blows, although the temperature is not very low, but it has strong permeability, which can quickly take away the heat of the human body, and can make the surface of your body as low as the surrounding temperature.

The reasons why there is no central heating in the south: 1. The humidity of the air in the south is relatively large, the thermal insulation capacity is relatively poor, and the difficulty of heating is relatively large. 2. The cold time in the south is relatively short, about two months, and the utilization rate of central heating equipment is relatively low.

3. Most of the winter in the southern region is heated by air conditioning, and it is not turned on all day, and the cost is relatively appropriate. There are many reasons for the lack of collective heating in the southern region, and the reasons for the lack of heating in the southern region are multifaceted and not singular.

The use of central heating in the south is not very efficient. In some places in the north, the number of days of central heating will reach half a year, and there will be general.

In three or four months, if there is central heating in some areas in the south, the total number of days will be much less than that in the north, and the heating system that has been built with huge sums of money is idle most of the time, and it is not worth it.

Due to the humid climate characteristics of the south, the buildings in the south are characterized by better ventilation (taking into account the climate of the four seasons) and poor thermal insulation. Buildings are well ventilated and poorly insulated, making it easy for indoor temperature to be lost. In humid climates, if central heating is used, the heat loss along the way of transporting the heat medium in the long-distance pipe network is very, very large, even if there are thermal insulation measures.

Since the construction of cities in the south has not considered the heating system during the construction process, the infrastructure for heating is almost non-existent. In addition, the winter temperature in the southern cities is relatively high, and you can survive the whole winter without heating at all.

Because of the warm climate in the south, there is generally no need for central heating as in the north. But in the southern winters, especially in some wet and cold areas, people still need to take some measures to keep their indoors warm and comfortable. Today, Jin Jinlai will introduce some common heating methods in the south to help southern friends who are new to heating to better understand.

Let's follow the golden flagship flag brother to find out.

1.Air-conditioned heating: Air-conditioned heating is one of the most common heating methods in the south.

With the heating function of the air conditioner, the indoor temperature can be raised to a comfortable level. The advantages of air conditioning heating are convenient, fast and easy to adjust, but the disadvantage is that the energy consumption is high, and it is not suitable for large-scale heating.

2.Electric heater heating: Electric heater heating is a more traditional heating method in the south.

The heating principle of an electric heater is to convert electrical energy into heat energy by means of electrical resistance heating. The advantage of electric heater heating is that it is convenient and easy to adjust, but the disadvantage is that it consumes more energy and is not suitable for large-area heating.

3.Floor heating: Floor heating is a relatively high-end heating method in the south.

The heating principle of underfloor heating is to dissipate heat through the floor, and the heat energy is evenly transferred to the whole room. The advantages of underfloor heating are comfort, energy saving, and aesthetics, but the disadvantage is that the installation cost is high and it needs to be planned in advance.

4.Gas heating: Gas heating is a relatively energy-saving and high-quality heating method in the south.

The gas is converted into heat energy through a gas boiler, and then the hot water is transmitted to the various rooms through pipes. The advantages of gas heating are energy saving, environmental protection and comfort, but the lack of filial piety is that the installation cost is high, and professional installation and maintenance are required.

In conclusion, there are a variety of options for heating in the south, each with its advantages and disadvantages. When choosing a heating method, you need to take into account your actual situation, such as the size of the house, budget, use needs, etc. At the same time, it is also necessary to pay attention to the safety and maintenance of heating equipment.

I hope the above introduction can help southern friends who are new to heating to better understand the heating method in the south and choose the heating method that suits them.

1. Central heating transports urban heat to the user's home through pipelines, and the heat source comes from a large cogeneration thermal power plant.

2. Boiler heating in the community The boiler room is built by the community, by burning natural gas, oil, coal, etc.
