How much heating do Southerners use in their homes?

I'm a southerner, what is heating, thousands of basically haven't seen it, and now when I come to the north to go to school, I know what heating is used for and how easy it is. I always feel that the north is cold, in fact, I now think that the weather in the north is really good, although the winter is very cold, but the house is heated enough, the winter is like summer, and the summer is not particularly hot, and the weather is pleasant in the morning and evening.

There is no such good treatment in the south, it feels cold in winter and hot in summer. In the south, there is no heating in the general family, and everyone installs air conditioning, which is generally not used much in winter, and is often turned on in summer. In winter, electric blankets are used a lot, and there are plugged in electric heaters.

But there is no heating in the south, and we have more underfloor heating on our side. I still once, when I went to Chengdu to play, we rented a hot rental house together, and then there was floor heating inside. It is not easy to meet such a house in winter, even if the equipment is better, there is floor heating, which is not available in the general home.

Anyway, there is basically no heating in our house, and the structure of the house is different. And it is not so easy to install heating in the south, whether it is in terms of the degree of cold in winter and so on, it is not achieved overnight, it has to be done slowly. I also like underfloor heating, and if it can be installed in the home in the future, it will definitely be very comfortable in winter.

There is another place that is particularly comfortable for the south, that is, the supermarket, which is heated enough in winter, and I think it is also a cool thing to work in it, which is warm in winter and cool in summer. However, the winter in the south is not so sad, the cold is not thorough, it is very good, the self-cultivation is particularly good, anyway, there is an electric blanket, and the winter is not so terrifying.

I am a northerner, living in Sichuan for more than 10 years, doing building materials business, as far as I know, Sichuan also has floor heating, but very few, the north is central heating, by the heating company through the embedded pipeline heating, and Sichuan there is no embedded pipeline, the new buildings are pre-planned to have heating, the later are cut off, do not need. Generally their own installation of the kind of natural gas is more expensive, the use of natural gas for combustibles, the cost is very high, most of them use air conditioning and electric heaters for heating, from a long-term perspective, economic and safety perspectives, but also have to be the safety and economy of geothermal pipelines is to lay pipelines to be troublesome, I personally want to use the ground heating, my father-in-law's family built by himself last year, in rural Sichuan, I designed for him, it turns out that every year in winter, children and the elderly are wearing thick clothes all day and night, and it is cold to touch, I specially customized an earthen boiler for him from a friend in the north, this year the old man is happy, the room is the same as the temperature in the building in the northern winter, zero 267 degrees, you don't need to wear so much at home, or it is recommended to have floor heating.

There are several reasons why there is no heating in the south:

1. The winter time in the south is short

Due to the large difference in climate between the north and the south, and the early winter, longer winter, and colder climate in the north, the heating period in the north is generally more than 4 months, or even as long as half a year. The south is relatively late in winter, the summer time is relatively poor, if the central heating in the south, the heating equipment is used for a relatively short time, the maintenance of the required funds is relatively large, the value is relatively small. This makes it difficult to show its true technology, and it will be beaten into the cold for a long time.

2. Insufficient funds and no need

The weather in the south is relatively humid, in the rainy season, in order to better ventilation, we need to sacrifice part of the insulation performance in the construction of the city, then the indoor heat is easy to lose, even if the south provides heating, it is difficult to maintain a warm feeling indoors. And the establishment of the heating system, it is necessary to build many thermal power plants and boiler rooms, and to dig up the ground to lay the heat transmission website, which requires a lot of investment in capital and manpower and material resources.

3. Too wasteful

You must know that the establishment of the heating system requires a lot of money, and the heating time in the south is only two months at most, while the heating time in the north is generally 3-4 months, so it is not cost-effective to spend a lot of money to get heating equipment. Moreover, the heating fee paid by the north is fully sufficient for the people in the south to turn on air conditioning to keep warm.

In addition, a lot of coal and natural gas in the south are transported from the north, which requires increased costs, so it is far less cost-effective to use air conditioning to keep warm.

4. The heating efficiency is not high

Compared with the northern region, there are more rivers and seas in the south, and the people in the south have the habit of opening windows for ventilation when they live, if the windows are opened for ventilation, the indoor heat will be lost while heating, and it is difficult to achieve good heating efficiency.

5. The structure of the house in the south is also not suitable for heating

In the northern houses, the walls are like sandwich biscuits, and the windows and doors are tightly repaired, all to keep warm. In the south, in order to keep out the moisture as much as possible, houses cannot be built as airtight as in the north. So, even if the heat goes down the heating pipe to your home, they can't stay and it's hard to keep it warm.

1. Humid climate is not suitable.

The climate in the south is relatively humid, especially in winter, it often rains, if the heating equipment is repaired to the south, it will rot in the humid climate for a long time, and it will cost a lot to repair. The climate in the south is relatively humid in all seasons, and this equipment is built there, and the service life will not be long.

2. Low efficiency.

The northern region will enter winter to November at the latest, and the south, at least until mid-December, the south is much later than the north, and in the spring, the south also warms up faster, so the cold duration is relatively short, which has spent a lot of money to build the heating equipment, just opened not long ago, it will be closed, and more than a year is idle.

3. Advocate adapting measures to local conditions.

According to the characteristics of hot summer and cold winter, it is recommended to adopt decentralized and local heating methods according to local conditions; At the same time, improve the winter insulation performance of the building. Encourage the use of renewable energy for heating. It is not advisable to build large-scale central heating heat sources and municipal heating pipe network facilities for building central heating.

The main heating methods in China are central heating and decentralized heating. The theoretical efficiency of central heating energy utilization is high, and it is suitable for continuous heating in the whole space during the long cold period, but there are also problems such as large project construction scale, long cycle, high one-time investment, difficult heat supply adjustment, serious air pollution, and inability to mobilize energy saving.

Decentralized heating has the characteristics of small construction scale, short cycle, flexible and convenient operation and management, and easy measurement. However, if coal is used, the heat source efficiency is low, the pollutant control is difficult, and the scope of application is limited by the influence of region, resources, environment, building type and living habits, but if electric heating and renewable energy are used, it is completely different.

The hot summer and cold winter areas involve parts of 14 provinces (municipalities directly under the central government), with a residential construction area of about 3.4 billion square meters and a population of about 100 million people, the winter is humid and cold, and when the outdoor temperature is lower than 5, people's discomfort is greater than the cold and cold areas of the same outdoor temperature, therefore, it is necessary to set up heating facilities in these areas for winter heating.

There are several reasons why there is no heating in the south:

1.The use of central heating in the south is not very efficient.

The number of days of central heating in the north will reach half a year, and there will be general.

Three or four months, but there are more warm weather in the south and shorter winters.

2.Southern cities have not considered the heating system in the construction process, and the investment in heating infrastructure construction is too large.

3.Due to the humid climate characteristics in the south, the buildings in the south are better ventilated and less insulated. 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 large, even if there are insulation measures.

As a result, there is no heating in the south.

1. Heating heat loss is related to four factors:

1.Outside temperature.

The lower the outside temperature, the greater the temperature difference from the body surface, and the faster the heat is lost.

2.Humidity.

Moist air has a greater thermal conductivity than dry air, and air humidity accelerates heat loss.

3.Wind velocity.

Wind speed strengthens heat convection and accelerates heat loss.

4.Ambient object temperature.

The temperature of the surrounding objects determines the speed of heat radiation heat dissipation between the human body and the surrounding objects.

Second, the impact of high air humidity on heating:

1.The higher the humidity, the better the thermal conductivity of the air. The thermal conductivity of still air is , the thermal conductivity of water is , the air at the same temperature, the greater the humidity, the more water vapor dissolved in the air, and the better the thermal conductivity.

2.The higher the humidity, the greater the heat capacity of the air. Heat capacity refers to the amount of heat that a substance needs to absorb to heat up. The specific heat capacity of water is the content of junior high school physics, and the air in a room rises from 5 to 10 degrees, and the higher the humidity, the more heat the air needs.

1. Due to the humid climate characteristics in the south, the buildings in the south have better ventilation and poor thermal insulation, which makes the indoor temperature easy to lose, and it is not suitable to install heating under such building characteristics.

2. The winter time in the south is short, and the equipment utilization rate is low.

This is because the temperature in the south is higher than that in the north, it is not too cold and the cold time is short, and the installation of heating is of little use, so it is meaningless.

Hello! Because the climate in the south is relatively hot, there is no need for heating, and generally there is no need for heating when crossing the Yellow River, and now air conditioners are installed at home.

Because the temperature in the south is relatively high in winter, air conditioning is generally used for heating, but in recent years, many places in the south have also adopted centralized gas supply.

Because the south is not as cold as the north, the temperature in winter is generally around freezing, so there is no need to use heating.

Because the south is like spring all year round, there is no need for heating.

There is a huge difference in heating between the north and the south, and there are three reasons why there is no heating in the south1. EfficiencyAt present, most of the boiler central heating used in China is simply water heating

This means that there is a need for a long and complex system of pipes to transport the hot water, and it is important to insulate these pipesHowever, the climate in the south is humid, and the moist water vapor has a high specific heat capacity, which leads to the hot water in the pipe quickly interacting with heat, and the hot water is basically warm water to your homeThe air in the north is dry, easy to keep warm, and there is little heat exchange, so the southern partners use other methods (air conditioning, electric stoves, etc.) to heat much more efficiently

Second, the structure of the houseThe structure of houses in the north is very different from that in the south, in order to keep warm and keep out the cold, the "sandwich" is mostly used"The walls are insulated, and the windows in the north are also smaller, which are easy to keep warmIn the south, due to humidity, good ventilation and sunlight are preferred, so the walls are more breathable and the windows are larger, which is convenient for ventilation and lighting

Why is there no heating in the South, country.

There is no heating in the southern winter, but homes are allowed to install heating separately, and air conditioning can also be used to heat the house. Heating refers to the north of China and countries with low average annual temperatures.

This is a facility used to protect against the cold in winter. Heating in a broad sense refers to the products and methods that allow people to get their heating needs, and is a product that increases the ambient temperature after heating through a heat source, and the heat medium reheats the air to form a heat exchange.

Heating refers to a central heating facility in a narrow sense. It transports the steam or hot water generated by the boiler by pipes (i.e., heating pipes) to the radiator (i.e., radiator) in the room or car body, which dissipates heat and increases the room temperature, and then flows back to the boiler to reheat and circulate. There are rules that require clean water to be used for heating in order to benefit people's health.

Clean water must be used for heating to benefit the environment. Clean water must be used for heating to help the company's image.

Why? There is no heating in the south in winter.

Heating can be installed in homes in the south, but due to the small number of heating users in the south, central heating is not yet mature, so most of the heating in the south is independently installed in residents' homes.

Buildings in the southern region do not emphasize warmth, but pay more attention to heat protection, shading, and ventilation, which ensures comfort in the rainy and humid summer. Unless all the houses in the south are demolished and rebuilt according to the standards of the north, even if central heating is realized, the warmth of the building is not good, and the heat will only be lost faster.

Moreover, there are generally no heating pipes in southern buildings. It is difficult to renovate an old building from scratch, and it is also difficult to do so in places where there are no heating pipes. This determines that if central heating is to be implemented in the south, it will be a big project and costly.
