The data on heating in the south shows that there is a big difference between the north and the sout

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.

There is no need for heating in the south. The winter in the south is short, and the temperature in the south is not very low, so there is no need to waste so much manpower and material resources on heating.

The difference between the climate of the southern region and the northern region, the northern region has a winter of up to four months or even half a year. However, the winter in the south is only a little more than a month at most, and it is not worth it to spend a lot of money on maintenance, so there is no heating service in many parts of the south.

The living habits of southerners and northerners are completely different, and when southerners live, they like to open windows for ventilation. This is a very bad behavior for heating, after all, if people open the windows, the heat dissipation of the whole room will be greatly increased, which leads to a certain waste of heating resources, and the efficiency of heating is not high.

Climatic characteristics of the south

1. Equatorial monsoon climate: located in the island area of the South China Sea south of 10 degrees north latitude. The average annual temperature is above 26 degrees Celsius, the annual accumulated temperature is 9,000 degrees Celsius, the temperature changes very little, and the rainfall is evenly distributed in the four seasons.

2. Tropical monsoon climate: including the southern part of Taiwan Province, Leizhou Peninsula and Hainan Island. The annual accumulated temperature is greater than 8000 degrees Celsius, the average temperature of the coldest month is not less than 16 degrees Celsius, the annual extreme minimum temperature is not less than 5 degrees Celsius for many years, and the extreme minimum temperature is generally not less than 5 degrees Celsius, and there is no frost all year round.

3. Subtropical monsoon climate: North China and South China belong to this type of climate. The annual accumulated temperature is between 4500 and 8000 degrees Celsius, and the average temperature of the coldest month is -8 0 degrees Celsius, which is the transition zone between the tropics and the temperate zone, and the summer temperature is quite high (at least 6 seasons when the average temperature is greater than 25 degrees Celsius, that is, 30 days), and the winter temperature is quite low.

Is it necessary to heat in the south, it is necessary, not all places in the south are like spring all year round, it is completely possible to take different heating methods according to different regions (or different times) so that the masses of people can fully feel the warmth of heating, the general process is to find the problem, put forward the problem, after the problem is found, according to their own knowledge and life experience to make assumptions about the answer to the problem Design the first plan, including the selection of materials, design methods and steps, etc, whether the results obtained by reanalysis are consistent with the hypothesis, so as to draw conclusions Not all problems reach the right conclusion at the first time Sometimes, due to the imperfection of the method, it is also possible to draw wrong conclusions Therefore, after reaching the conclusion, it is also necessary to reflect on the whole process The general methodological steps of the experiment: asking questions, making hypotheses, making plans, implementing plans, drawing conclusions, expressing and communicating

The most commonly used methods in science include observation method, experimental method, investigation method and data analysis method

Observation is a basic method of science Scientific observation can be made directly with the naked eye, with the help of magnifying glasses, microscopes and other instruments, or with the use of cameras, video recorders, video cameras and other tools, and sometimes it is also necessary to measure Scientific observation should have a clear purpose; Observations should be comprehensive, meticulous, and realistic, and recorded in a timely manner; Be planned and patient; Think positively and record in a timely manner; To exchange views and discuss The design of the experimental protocol should be carried out closely around the questions and hypotheses raised When studying the influence of one condition on the research object, the experiment carried out under the same conditions except for the different conditions is called a controlled experiment General steps: find and ask questions; gather information related to the issue; make assumptions; design of experimental protocols; Conduct experiments and record them; analysis of experimental phenomena; Conclusion Investigation is one of the common methods of science When investigating, we must first clarify the purpose of the investigation and the object of the investigation, and formulate a reasonable investigation plan During the investigation process, sometimes because the scope of the investigation is very large, it is necessary to select a part of the survey objects as samples During the investigation process, it is necessary to record truthfully The results of the investigation should be sorted out and analyzed, and sometimes the statistical methods should be used to collect and analyze data is also one of the common methods of science There are many ways to collect information Go to the library to consult books and newspapers, and visit relevant people, The form of information includes text, data, and audio-visual data, etc., and the information obtained should be sorted out and analyzed, and answers and clues should be found from it.

In the past, the friends in the south always envied the friends in the north for heating, but now the south basically uses heating. It's just that there may be some differences in the way of heating in the north and south, most of the north is collective heating, and some are separate heating, while the south basically uses separate heating. Next, I will tell you about the relevant situation of winter heating in the south.

1. Floor heating. Underfloor heating is divided into water heating and electric heating. If it is plumbing, we need to boil the hot water in the underfloor heating to 50 to 60, and we can make a 100 house warm up to 20.

If it is electric heating, it uses electricity as an energy source, and then converts 100% of the electrical energy into heat energy, and then heats the surrounding air. Comparatively speaking, the temperature required for underfloor heating is lower, but the amount of the latter part of the day is about 20 cubic meters, and the cost will be slightly more.

Second, radiators.

A common heating tool in the south is the radiator, because the radiator will heat faster than the floor heating, and it does not need to be turned on for a long time, so the use of radiators for heating is very popular in the south. If a gas wall-hung stove is used, the hot water in the radiator needs to be boiled to 70 to 80, and only this temperature can warm up a 100-year-old house to about 20, and it can also maintain a comfortable type.

3. Household air conditioning.

If it is a household air conditioner, you can turn it on when you need to use it at home. However, household air conditioners should not be used for a long time, because long-term use will cause the air in the house to become particularly dry, and the dust is easy to increase, affecting the overall comfort. In more serious cases, it can even produce respiratory diseases, which endanger people's health.

Fourth, summary. The above is the three ways to share the use of the South to change the rapid warmth, each of which has its own advantages and disadvantages. When choosing a heating method, each family must choose according to the specific situation of their own family.

Because the situation of each household is different, the effect of heating needs to be different. Therefore, we must be cautious when choosing a heating method.

Finally, I would like to remind you that when installing heating equipment, you must not be greedy for cheap and choose some three-no products. Because these heating devices are used at home for a long time, they are prone to danger if they are inferior products. Therefore, we must look for qualified products when purchasing.

1. Air conditioning and heating.

Air conditioning is a commonly used heating method in the south, although it is convenient, but the heating effect is not very good. Because the air conditioner sinks and the heat rises, air conditioners are generally installed above people's heads, so heating in winter will be more uncomfortable. Because all the heat is concentrated in the middle and upper parts of the human body, it blows dry mouth.

2. Electric floor heating.

The investment cost of electric floor heating is not high, the heating speed is fast, and the comfort effect is also very good, so it is a relatively good choice. However, after the user uses it, they are afraid of its high operating costs, not that they can't stand the cold, and they are not willing to open it at all, resulting in the floor heating in Pisheng's home reduced to a furnishing.

3. Gas wall-hung boiler heating.

The gas wall-hung boiler consumes natural gas for heating, and there are two options at the end of the heating: floor heating and radiator, which is suitable for families with different needs. Although the gas wall-hung boiler is slightly lower than the electric heating in terms of operating costs, a family of 100 square meters has to pay at least 1,000 yuan a month, which is still difficult for ordinary families to accept.

Fourth, air can be used for floor heating and air conditioning.

Air energy floor heating and air conditioning is a new generation of energy-saving and environmentally friendly equipment, which can be heated and cooled, and looks similar to air conditioning. However, in terms of effect, the air energy floor heating air conditioner is much stronger, and its heating end is similar to the wall-hung boiler, with two options of floor heating and radiators, and the comfort is very good. However, due to the fact that the southern building grip core is not insulated, you can choose to dig next to the heating, which is ready to use, which can save some unnecessary consumption.

There is no heating in the south** Reason:

1. High investment.

Because the southern city has not considered the heating system in the construction process, the heating infrastructure is almost non-existent, if the future to central heating, then the infrastructure construction investment is not able to bear, but also everyone can not stand.

First of all, it is necessary to rebuild or rebuild the power plant, hydropower generation is not possible, it must be thermal power generation to burn coal, and the steam burned can be used as a heat source for heating. One thermal power plant is not enough, and in the city it is necessary to build several large boiler rooms, countless small boiler rooms.

It is not enough to have a heat source, but also a heat transmission pipe network, some go from the ground, and large pipes with a thickness of dozens of centimeters must be erected on both sides of the street, and some go from the ground, and each street must be excavated again.

It's not enough to have heat pipes on the streets, but also in the buildings, and now almost all the building structures in the south don't take this into account, and they have to be re-erected on the walls.

2. The use efficiency is not high.

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.

3. There is a lot of waste.

The waste of central heating is also very large, due to the unreasonable design of the heating system, the user can not control the room independently, if it is hot, I have to open the window to adjust the room temperature, about 7 of all the heat is wasted.

At present, office buildings, classrooms and other public buildings, after work, after school, weekends, New Year's Day, Spring Festival and winter vacation, when there is no one indoors, as usual, the waste is obvious.

Here are a few ways to keep warm in the South

1. The building uses insulation materials to keep warm. When building a house, the developer will put an insulation layer on the walls of the room to achieve the effect of the room being cool in winter and cool in summer. This is a very environmentally friendly method of ecological warmth.

2. Floor heating to keep warm. Nowadays, home decoration will be equipped with floor heating, which is comfortable and warm, environmentally friendly and healthy.

3. Air conditioning keeps warm. Homes are now air-conditioned, and it is comfortable to turn on the heating in the coldest weather. This heating method is fast, economical and cost-effective.

4. Wall-hung boiler keeps warm. Wall-hung boiler is more comfortable than air conditioning, more cost-effective than floor heating, and is the most applicable method.

5. Electric grill table for heating. When it's not too cold, you can sit around the electric grill table to keep warm, and you can also dry clothes, the most traditional way to keep warm.
