How was heating in the north before the invention of heating?

This lack of heating still exists in the countryside of the past or in the north. In the past, there were mostly bungalows, and the main heating methods were stoves and hot ondols. So there used to be some particularly interesting memories.

When I went to school, I lived on campus, and on a certain weekend in winter, the whole dormitory went out to deliver charcoal to the dormitory, and this was a quota, how much a dormitory was, how many classes were. In winter, the place near the stove is the most popular, and when class is over, students who don't go to the toilet sit around chatting and making a fire. In the winter in the dormitory, we sometimes don't eat at night, take some meat and rice from home, boil porridge in a porcelain jar, and cook noodles to eat.

When I was at home, I roasted sweet potatoes and potatoes to eat, and we don't usually grow sweet potatoes there, so baked potatoes are often available, and roasted sweet potatoes are not often available, so I order pickles, which I think are very delicious.

In the north, they all use charcoal fire plates, and there are also those kinds of kang to keep warm.

In the past, rural ondol households mostly used "braziers" for indoor heating. Put the smokeless charcoal burner in the stove pit into a large iron basin and burn it to heat up. The city uses a stove for cooking, boiling water, and heating.

When I was a child, there was heating, but some people were reluctant to burn the kang to resist the cold, some people were about to spend ten days and a half a month during the New Year, and some people were willing to use coal to burn in the house to be particularly warm. In the past, the windows were not well sealed, and plastic sheets were nailed to the outside, and there were also old people who lit braziers, and there were also earthen stoves that were connected to the kang, and so on.

There is a kang in the house, and a lot of wood will be prepared before the arrival of winter, and then when winter comes, the kang will be burned, and if you don't put some quilts under the kang when you sleep when you are a child, you can be scalded awake.

For children, in addition to heating the fire, the biggest fun is to make some winter snacks by themselves, among which roasted corn and roasted sweet potatoes are most children's winter favorites. I remember when I was a child, I always liked to put one or two corn and sweet potatoes next to the fire, although I would be confused by accident, but in the end I would still eat it with relish. In my opinion, it is very pleasant to eat your own warm food while listening to the adults chatting about homely things.

Not only that, but in winter, rural children even do their homework is sitting next to the fire, high stools and low stools are matched, it is a simple desk, children can do homework while helping adults look at the kang peanuts on the fire.

As a northern child who lived and grew up in the countryside, the deepest impression of winter is the scene of the whole family sitting around the fire. The winter in the countryside is always extremely cold, not to mention going out, that is, leaving the fire at home will freeze people to stomp their feet, most rural families have neither air conditioning and heating, but also too expensive to use electricity heating, so the fire on the spot has become the only way for rural people to heat up.

Nowadays, many places still maintain a kind of equipment that uses a cylindrical earthen stove for heating, although this thing is not large, but the whole house is still very warm, especially with a chimney walking from the house, this room will be warm.

Every house in the north has a fire kang and also uses a brazier. The windows are covered with plastic to prevent the cold from entering the house.

The stove and the kang are added, the snow is falling outside, the house is warm, a few plates of peanuts and melon seeds, and an idle book, it is really beautiful.

The northerners used to be kang, because it was cold, if it was very cold, they would boil the water in the pot and then go to the kang.

I think they're probably like a southerner.

When I was young, we had a stove in our house, and we could put firewood and coal in it, and when the stove was hot, there would be heat in the house.

Coal is the main fuel for winter heating in northern China, but with the development of heating technology and equipment, the heating energy structure has also undergone some changes. At present, the heating area with gas, oil and electric potential as heating energy sources is increasing year by year, which is accepted by more and more people, and the heating energy structure constructed by coal, gas, oil and electricity is gradually becoming reasonable.

Heating refers to the supply of heat to the building and maintains a certain indoor temperature, which is a social service to solve the basic living needs of residents in northern China for winter heating.

Heating in the north is in the form of collective heating and individual heating.

1. Collective heating.

It is mainly the heating company or the boiler room of a community as the heating provider, they use a large enough boiler to build a heat source in the form of coal, gas or electricity, and then send the heating to the households in the community through special heating pipes. The advantage of this method is that it can evenly supply heating to any part of the community.

2. Household heating.

It is a way for each user to use a separate heating system for heating, which is very popular, because users can choose according to their own needs and preferences, and truly realize on-demand heating. Moreover, this heating method has also given birth to many new types of heating equipment, such as electromagnetic wall-hung boilers, resistance wall-hung boilers, gas wall-hung boilers, air energy heat pumps and so on.

Heating

It refers to the facilities used to protect against the cold in winter in the north of China and countries and regions with low average annual temperatures. In a broad sense, it refers to the products and methods that allow everyone to get the heating needs, and are products that increase the ambient temperature after heating the heat medium and then heating the air through the heat source.

In fact, the earliest design requirements were mainly for water mains to freeze in winter in areas where the temperature would reach below 0C. In short, heating is an ancillary service or incidental to the water supply needs of urban residents.

Radiator. Radiator is a kind of heating-based heating equipment. It is mainly used in the northern region where the winter is cold, and has the effect of keeping warm, and cast iron radiators were mostly used in the past, but now more materials have been developed.

Cast iron radiators have gradually withdrawn from the market stage, steel radiators, copper-aluminum composite radiators, aluminum radiators and other new radiators are superior to cast iron radiators in terms of material and production process, becoming the most mainstream spine radiator on the market.

In cold areas such as Northeast China, heating has replaced fire walls and ondols as people's new heating equipment.

Summary. 1. What are the most advanced heating methods in rural areas?

1. Solar energy. Solar heating mainly includes three parts: solar heating system, circulation system, and heat dissipation system.

The solar collector heats up the water to 50-60, and sends the hot water to the indoor cooling system to dissipate the heat by the circulation system, and the water after heat dissipation is circulated to the bottom of the solar collector, so that the cycle repeats, the continuous hot water has been dissipating heat to the room, so as to achieve the purpose of heating.

2. Hanging kang. The main body of the hanging kang is an efficient prefabricated and assembled overhead fire kang structure, which can achieve a double-layer heat dissipation effect, so that the heat in the cushion soil in the kang can be dissipated from the overhead part to the room. The 4 walls in the kang, especially the cold wall part, are equipped with insulated houses to reduce the heat absorption of the cold walls.

The reform of the structure in the kang makes the flue gas evenly distributed and expands the heat dissipation area in the room. The hanging kang also increases the plug plate on the furnace eye, so as to control the convection in the kang and achieve the effect of heat preservation and safety.

3. Simple floor heating. This kind of floor heating only needs to dig a one-meter square pit in the room, install a chimney, fill it with flammable materials such as corn stalks, corn cobs, cotton stalks, sawdust, etc., compact and ignite, and cover it with a stone slab with air intake holes, and a simple floor heating is built.

State-of-the-art heating in the countryside of the North.

1. The first working principle: the heater is a heating element, and his task is to make the room warmer and imitate the peace, just like boiling water in a kettle. The difference is that the kettle is a closed container relative to the water, and the room is not closed relative to the air.

Think about it, if you pour cold water into the pot while boiling it, the water will never boil, and all the heat of the stove will be absorbed by the heating of the cold water. The same goes for heating the air in the house while heating. The cold air from outside keeps coming into the house, and the room will never be warm.

Heating works by heating the air, what if you avoid the above problems? It is to place the radiator in a place where the window is eyed, and the cold air such as the door is easy to enter the house. As soon as the cold air comes in, it is heated into hot air by the radiator.

The hot air rises and forms a convection current with the cold air in the house. The cold air circulates to the vicinity of the heating and is heated into hot air. When the hot air circulates in the house, the room is warm.

What happens if you leave the radiator somewhere else in the house? The heating side heats the air. And the cold air from the outside world is constantly coming in from outside the house.

After the cold air has cooled the room, the radiator heats him up, and the room will naturally not be warm. Therefore, the heating system, including the radiator type electric heater (Shanghai seems to be called oil tin), works in the above way. And not the so-called heating of the object.

As you can tell from the name of the heater, it is the gas that warms up.

2. The second working principle: the working principle of the radiator is to transform the original radiator cavity into an independent circulation system, add a small amount of superconducting liquid to it, and only take water in the connecting pipe at the bottom of the radiator. When the water flows in the connecting tube of the superconducting radiator, the superconducting liquid is used as the medium to transfer heat, and the superconducting liquid is heated to cause the molecules and atoms of the substance to collide and rub against each other to produce heat energy, resulting in the phenomenon of aggregation and fusion, so that the superconducting medium is instantly heated at high speed, and the activated and gasified high-temperature gas radiates outward through the surface of the radiator to dissipate heat.

At the same time, it is condensed and flows back to the heat source duct, where it is activated for vaporization. Work repeatedly to achieve the purpose of energy saving and heat dissipation. The amount of heat dissipation of the superconducting radiator depends on the preparation of the superconducting liquid in the radiator and the amount of superconducting liquid added to the radiator, the material of the radiator, and the temperature of the water in the connecting pipe.

It has the advantages of low starting temperature, fast conduction, high temperature, water saving of more than 80%, easy installation, time-saving and material-saving, corrosion resistance, long service life, safety and reliability, energy saving and environmental protection.

Northern heating process: the heat source of central heating, generally there is a thermal power plant to provide hot steam, which is transported to the heat exchange station with pipelines, and the heat exchange station turns the heat into hot water and transports it to thousands of households, just like tap water. Hot water passes through the heat sink in the room, dissipating the heat into the room.

When the indoor temperature reaches 20 degrees or more, it is more comfortable.

The northern part of China has a temperate monsoon climate, and some areas have a plateau climate.

The characteristics of the temperate monsoon climate are: hot and rainy summer, cold and dry winter, and the average temperature in winter is below 0 degrees Celsius.

The plateau climate is a climate formed on the plateau surface with high altitude, wide ground, and gentle undulations. The climate of the northern plateau in China is mainly distributed in the Loess Plateau, which is characterized by the following characteristics: with the increase of altitude, the air, water vapor and dust decrease, and the direct solar radiation is enhanced, and the ultraviolet radiation is particularly obvious; However, the effective radiation has also increased.

On the snow-covered plateau, the reflectivity increases and the ground absorbs less radiation, so the net radiation is smaller than that of the plain at the same latitude.
