Every winter, "heating" and "heating" will surely become the topic of discussion after the meal of the people of the country. After this round of strong cooling, the topic was discussed again. The national cold wave has come, and it is probably the most comfortable home in a heated home. "You are heating in the north by heating, I am shaking in the south to warm up." "The people of the South are frozen and stupid. The northern part of the heating can't feel this sadness." "Eating ice cream in the north is the greatest respect for heating."


So how do other countries heat up? The most popular heating method relies on natural gas and electricity, while Japan and South Korea rely on the characteristic furnaces and warmth; Sweden and Austria use energy for secondary use; the most special is Hungary, which recycles used banknotes every year for fuel. That is, "burning money for heating", this kind of heating method is a bit "meat pain". Either way, there is snow in the winter and you drink tea and read a book in the house. Thanks to the heating!


Russia: Heating represents the arrival of winter


Russia, the title of "Ice Country", is one of the coldest countries in the world. In the eyes of the Russians, snowing is a very common thing. Only when heating starts, it represents the arrival of winter.


Today, Russia has the world's largest district heating system, with 81% of households using central heating and about 2 million workers responsible for building, maintaining and managing heating facilities. Starting from October 1st every year, when the temperature in Russia is lower than 8 degrees Celsius for 5 consecutive days, the relevant agencies will start the heating system. The first heating targets are kindergartens, primary and secondary schools, medical units, and then in half a month. , to achieve all heating in succession.


Ivanosina, who lives in Moscow, is a housekeeper. She said: "It's not difficult in winter. The temperature in the room is above 25 degrees. There is heating in the room. Wearing a single coat is enough." Russia There is a difference in heating time across the country. The heating time in Russia spanning 11 time zones is long and short, usually more than 6 months. The length of time to extend is determined by the latitude of the area. For example, the heating time in St. Petersburg will last for 7 months. Of course, if the temperature in May is still very low, then the heating will be extended accordingly.


Japan: Frequently appeared in Japanese TV dramas


If you are familiar with Japanese TV dramas, you will find that the furnace is frequently seen in Japanese TV dramas: After the family gets off work, they will chat around the oven for dinner. The Japanese oven, also known as the warm table, is a quilt on a double-decked table with electric heaters under the table. When the legs are pushed in, it can have the effect of heating and cold resistance. So why is it being stoved? Due to the earthquake in Japan, houses have to be built lighter, but such a structure is not conducive to heating projects, and is not conducive to warmth; plus Japan is poorly resourced, heating energy consumption is too large, not suitable for central heating.


The old-style oven is a square small table. The table is covered with a quilt that covers the entire table and the ground to prevent heat loss. Then put it on the table top. There is a tens of centimeters below the table. At the bottom of the raft, there is a stove box with fossils or briquettes in the oven, and a wooden floor on the stove. When heating, people put their feet on the hot wooden floor covered by the quilt, and they can feel the warmth instantly. With the advancement of technology, the furnace was continuously transformed, the small table became a rectangle, the legs were raised, and some even equipped with stools to facilitate people to eat, study or work on the same table; It has also become an electric heater, eliminating the need for people to constantly add fossil or briquettes to the stove.


The new type of furnace can be placed at random. When people decorate the house, they no longer fix the position of the furnace. Instead, they lay a layer of mat on the ground, put the furnace with electric heater directly on the mat, and people put their legs into it. Inside the quilt, you can feel the warmth of winter.


South Korea: Warmth continues the life culture


The older generation in Korea is accustomed to using warmth. It works by burning heat in the kitchen or outside the stove, and then heating the room through the pipes under the house, similar to the Chinese floor heating, but the Korean warmth is full-floor, covering the house. The corners of the corner fall. How big is this full-floor warmth? The five-bedroom warm-up room of a family living in Gyeongsangnam-do has an area of 174.9 square meters. To this end, the Korean Record Research Institute also awarded the “Single Warm and Large Area Warm House” certificate to the family in 2013.


Usually, the warmth of Korea is combined with the board of the hall, which is closely related to the climate of Korea. The main climate in South Korea is continental and maritime, with obvious changes in the four seasons, hot summers and cold winters. Therefore, in order to cool down, the Koreans will choose a good floorboard during the renovation; in order to warm, the floor of the house is higher than the ground level, and the warm room is not large, and it is easy to maintain a warm temperature. The combination of the hall wood and the warmth has become a major feature of Korean houses.


In the winter, the warmth provides the right temperature for the house, so that Koreans can continue the "sitting-style" habits, especially for families with children. In the winter, children crawl on the ground and parents don't have to worry. Will be cold and sick.


United States: The fireplace is mainly for the atmosphere


There are about 117 million households in the United States. According to the Census Bureau, 50% of households use natural gas for heating, 39% use electric heating, and the rest use heating oil, propane, wood and other means of heating. Due to its location in the northern hemisphere, most of the buildings are double glazed or triple glazed, and the doors are mostly double glazed, which is conducive to the maintenance of indoor temperature.


In the big cities of the United States, people live in apartments, and apartments are heated by electricity. Each household has a boiler and a water heater. The water heater and boiler are placed in separate cubicles to ensure 24 hours of hot water supply. New York apartments are heated by central air conditioning. The Tenant Benefits Guide specifies the heating time and temperature of the rental house. From October to May, the landlord must provide heating to the tenant. The outdoor temperature is below 12 degrees Celsius and the indoor temperature must reach 20 degrees Celsius. If the landlord does not provide heating, the tenant can complain to the local government at any time.


In small towns in the United States, people live in villas. Because the villas are separate buildings, heating oil is used for heating. There is a boiler in the basement of each house that is responsible for heating and boiling water. Typically, cottages require more than 800 gallons of heating oil throughout the year, while large villas require more than 2,000 gallons and float at $4 per gallon. In general, summer oil prices are cheaper than winter. In addition to conventional equipment, the fireplace is a plus item for the house. The fireplace is usually placed in the living room. Most Americans do not use a fireplace to warm the winter. Only when it is an important holiday such as Thanksgiving, Christmas or New Year, friends and family gather together. Together, the fireplace will be used. At this time, the fireplace is the best prop for the atmosphere.


Austria: Waste-to-energy heating into a model of the EU circular economy


The EU has always advocated “circular economy”, and the rubbish trade between Austria and Italy is a model of success. In 2017, EVN, the second largest public utility in Austria, imported 70,000 tons of garbage from Rome, Italy. The rubbish was transported to a garbage collection plant 60 km west of Vienna. The plant's capacity to dispose of waste is 500,000 tons per year, and this 70,000 tons of waste can generate more than 550,000 megawatt hours of electricity. EVN sells electricity, heat and gas converted from garbage to meet the heating needs of Austrian residents.


Germany: indoor minimum temperature must not be lower than 20 degrees Celsius


In 1946, the Arctic and Siberian colds swept through Europe, and the Germans ushered in the "coldest winter." However, at the time, German households did not have heating or electricity, and the outdoor reached minus 20 ° C. Hundreds of thousands of Germans were killed in this “no-warm crisis” because of hunger and cold. Later, the German government targeted “allowing every household to use heating”, and each city built a thermal power plant to centralize heating. Berlin has the largest central heating network in the country. There are 1,875 kilometers of heating pipes in the city for 1.2 million people. The heating season starts in October and ends in April of the following year.


The government also strictly stipulates the room temperature of renting houses. From the perspective of comfort and energy saving, the bedroom should be 16 ° C, the living room is 20 ° C, the study is 22 ° C, and the bathroom is 24 ° C. Monus, an energy policy expert living in Berlin, said: "The landlord must provide heating when the room temperature is below 18 ° C. If the indoor temperature is below 20 ° C between 6 am and 12 pm, the tenant can go to court to sue the landlord. According to the government regulations, after the heating is turned to the maximum and the room temperature still cannot reach 20 °C, then the house is regarded as a "defective house", and the tenant has the right to request to reduce the rent; if the heating is completely impossible, the tenant can request the rent freely, and Have the right to cancel the rental contract.


Sweden: new green energy heating


Sweden is one of the countries around the Arctic. The winter is long and cold, so heating is an important issue related to the quality of life of the Swedes. In Stockholm, Sweden, there is one more way to heat up – new green energy heating, which provides heat to the residents of the city through the heat generated by the data center. The data center is called "Stockholm Data Park" and is operated by the municipal government and local heating companies. The major data centers are joining in, for example, popular social platforms and video sites, as long as people send photos, blessings, and watching Video programs, webcasts, etc., the server will run fast, the heat generated can become the energy of heating.


After the cold water flows into the data center, the “Stockholm Data Park” specializes in making pipes for the water that has warmed up after the cooling process, allowing them to flow into the factory and then distributing them to households to provide heat to the home. Mattson, head of business development at Stockholm Data Park, said: "More and more companies hope to enhance their reputation and build their brand image by strengthening their awareness of environmental climate." Currently, the data center operated by H&M, a clothing retail chain, has joined. . H&M not only sells the waste heat, but also enjoys the free cold water provided, which saves a lot of money and saves a lot of money. According to Matson, it is expected that by 2018, the “Stockholm Data Park” will be able to heat 2,500 residential apartments; it is expected to meet more than 10% of all heating needs in Stockholm by 2035.


Sweden is not the only country that is trying to heat a new green energy source in a data center. Finland, the United States, Canada and other countries have similar project tests. These countries are heating small towns, but Sweden decided to use this heating method from the capital. Stockholm began to spread, and then expanded to the national level, becoming a pioneer in leading the concept of green energy.


Hungary: The central bank sends "money bricks" for welfare groups to burn money for heating


Hungary is the only country in the world that recycles worn paper money every year as a fuel. At this time, the old banknote has another place: it is pressed into a “money brick” for the welfare groups to burn “money bricks” for heating. Hai Laiyi, head of an autism children's center in Misqualo, a city in northeastern Hungary, said: "This is a very effective charity. For us, it is like a charity to help us save some of the heating costs." The bricks are flammable and hot, only a little bit of wood is needed, and the room is very warm.” Hailaiyi estimates that the “money brick” provided by the Hungarian Central Bank saved about 6 of their autistic children’s centers. Wan Fulin's heating costs.


China: Coming into large-scale clean heating mode


China's heating model has been dominated by coal burning. In recent years, in order to improve environmental quality and improve residents' living standards, large-scale implementation of “coal to gas” and “coal to electricity” projects in the northern heating area has been carried out in the north since the heating season. In terms of air quality, the results in 2017 are obvious. There are no smog days in many places, and respiratory diseases are also reduced accordingly.


In the process of large-scale clean heating, “coal to gas” has affected the heating of residents due to the “gas shortage”, which has affected industrial gas and taxi gas, causing a lot of inconvenience to production and life. Air source heat pump heating has the best effect, the cleanest and most energy-saving in the centralized heating mode that has been implemented, and can be divided into household heating and central heating. It is highly praised by users and the government. It is expected that a larger implementation scope will be obtained in 2018.
