How does geothermal heat work? How does geothermal heat come about?

The water supply temperature of the low-temperature hot water floor radiant heating system should not exceed 60, and the working pressure of the heating system should not be exceeded. Underfloor heating systems should be cleaned once a year before use. Here's how:

First close the inlet and return valves connecting the conduit, then open the filter, take out the filter and clean it, check whether the filter screen is damaged or blocked, if there is damage, it should be replaced with a filter screen of the same specification, and it can be installed as it is (note: in the process of disassembling and assembling the filter screen, do not let debris enter the pipe). In the process of starting water supply or using the floor heating system, air may accumulate in the pipeline, which affects the heating effect, and the release valve of the water distributor and collector can be opened to discharge the gas, and the method is the same as that of traditional heating.

The water flow of each branch of the system can be adjusted by adjusting the ball valve on each branch, and the purpose of controlling the temperature of each part can be achieved, but the adjustment should be cautious so as not to affect other branches. The floor heating pipe laid under the ground is only about 3-4cm away from the floor surface, and it is easy to hurt the floor heating pipe by smashing and knocking on the ground, so it is strictly forbidden to knock and impact the ground where the floor heating pipe is laid, and it is strictly forbidden to wedge any sharp object into the ground to prevent damage to the floor heating pipe. When you need to place heavy items (more than 2 tons of square meters) on the ground, please contact the property management company or our company first.

When the user really needs to drill holes in the roof, it is important to pay attention to the depth of the drilling hole should not exceed the thickness of the floor slab structure to prevent damage to the upper floor heating pipes. There are many exposed pipes near the water collector, so attention should be paid to protection, and it is best to add a protective cover. It is strictly forbidden to place high-temperature heat sources near the water collector and on the ground where the floor heating pipes are laid to prevent damage to the pipeline system.

When there is no heating in winter, attention should be paid to protection to prevent the water separator parts from cracking and the water in the heating pipe from freezing and blocking the pipe. When you encounter problems that you can't solve during use, such as no heat, water leakage, etc., please contact Reference: China Education Development Network.

Geothermal heat is gradually accumulated by the earth in the long process of evolution, and the heat stored in the interior of the earth is a natural energy source, also known as underground heat. The generation of geothermal heat is mainly due to the heat released during the transformation of radioactive elements in rocks, and is the main energy source for volcanoes, hot springs, and crustal movements.

Low-temperature hot water radiant heating (referred to as plumbing) The plumbing system uses low-temperature hot water as the heat medium, and heats the surface through the special floor heating pipes laid under the indoor ground (such as cement floor, tile floor, wooden floor), and uses the entire ground as the heat dissipation surface to evenly radiate heat to the room, which is an energy-saving heating system that adjusts the microclimate of the room.

Low-temperature hot water radiant heating originated in developed countries in North America and Northern Europe, and the technology has been used and developed in Europe for many years, and is a very mature and widely used heating technology in Europe.

At present, it has also been widely used in China. Low-temperature hot water radiant floor heating has the characteristics of comfortable thermal feeling, stable heat balance, energy saving, maintenance-free, and convenient management, which is an extremely ideal heating method, especially suitable for large-area and long-term heating.

In recent years, geothermal heating has been more and more popularized in the north, not only in the cold winter to ensure the room temperature, but also has the role of saving space, clean and environmentally friendly, the correct use of water system ground radiant heating is very important, the use of good is green, environmental protection, energy saving, health care, the best choice for residential heating, so the design is the foundation, construction is the key, the pipe is the premise, the correct operation and maintenance is the guarantee. So what problems should be paid attention to in the operation of geothermal heating?

First of all, look at three **:

Save room space:

Reducing the space area where the conventional heating method heating is located, can save 6-10% of the actual area of the precious room, that is to say, a 100 square meter of the room due to the placement and decoration of the radiator, will lose 6-10 square meters of the living area in vain, if 3000 yuan square meters, then will lose 18000-30000 yuan, which does not include the cost of decoration materials and labor costs required for the decoration of radiators, and the choice of geothermal heating can save all this cost.

Energy saving: The temperature distribution in the hall along the height direction is relatively uniform, and the temperature gradient is small, which reduces the ineffective heat loss. Practice has proved that the design temperature of the radiant heating room can be 2-3 °C lower than that of the radiator installation method, but the same comfort can be obtained, so as to reduce the heat supply and save energy. At the same time, heat loss is low due to low temperature transfer.

radiant heating and cooling

Raise or lower the temperature of one or more surfaces in the inner surface of the envelope to form a hot or cold radiant surface, through which the radiant surface provides cooling to the room by means of radiation and convective heat transfer.

JGJ 142 - 2012 Technical Regulations for Radiant Heating and Cooling).

Now there are two most common types: water floor heating and electric floor heating.

Water floor heating is to dissipate heat through the heat pipe laid under the ground, and the water flowing in the heat pipe is driven by the heat source equipment (hot water boiler, heat pump), etc., to complete the circulation of heat source, heat pipe, heat source, and the water after the temperature is reduced is returned to the heat source equipment to heat to the set temperature, which is a closed cycle.

Electric floor heating is generally through the laying of power cables under the ground, through the reflective film under the cables, the heat is dissipated upward. The cable itself is a heat source device.

The principle of geothermal heating is that the heating pipes are laid under the tiles or floors in the home according to a certain rule, and the hot water in the boiler room will flow through these heating pipes in winter, and the heat will be dissipated upward, thus playing the role of heating.

As the name suggests, underfloor heating is a layer of heating under the floor, and these devices are heated with electricity, and the heat emitted makes the floor warm. The principle is similar to that of an electric furnace.

At present, most buildings use floor heating for heating, which heats the bottom air first, and then rises and the cold air descends to form a small circulation, which quickly warms the whole house. This is the most efficient way to heat your home.

The geothermal energy that we have here is a lot of pipes in the floor, and it's natural gas, which means that the heat is going through the pipes under the floor.

This makes the floor hot, but it's not recommended because it's expensive and the time to heat is slow.

Geothermal heating has been widely used because of its good effect.

Geothermal heating is a special floor heating pipe laid under the indoor ground, the pipe is heated by hot water (gas) to heat the surface, and the whole ground is used as a heat dissipation surface to evenly radiate heat to the room, which is an energy-saving heating system that adjusts the microclimate of the room. The heat source can still be used in the original boiler or natural gas heating source. Its advantages are that the "dark circles" are very good.

It is a new type of thermal regulation. Very popular with users.

Geothermal energy is the natural heat energy extracted from the earth's crust, which comes from the lava in the earth's interior and exists in the form of heat, which is the energy that causes volcanic eruptions and **. The Earth's interior can reach temperatures of up to 7,000 meters, and at depths of 80 to 100 miles, the temperature drops to 650 to 1,200. Through the flow of groundwater and the surging of lava into the earth's crust 1 to 5 km above the surface, the heat can be transferred closer to the surface.

The hot lava heats up the nearby groundwater, which eventually seeps out of the ground. The simplest and most cost-effective way to harness geothermal energy is to take these heat sources directly and extract their energy.

Humans have long used geothermal energy, such as hot springs for bathing, medical treatment, underground hot water for heating, building greenhouses for crops, aquaculture, and drying grains. However, it was only in the middle of the 20th century that geothermal resources were truly recognized and exploited on a larger scale.

When many people watch Korean dramas, they will find that many people in Korean dramas like to sit on the floor. It's the same whether it's a cold winter, so many friends will say, won't it be cold? In fact, many homes in Korea are equipped with ambiguous floors, so they will not be cold.

After the electric heating cable is energized, the working temperature is 40-60 degrees Celsius, and the heat dissipation surface is the ground (or wall, top surface). 2.How water underfloor heating works:

It is to lay pipes under the indoor floor (such as cement floor, tile floor, marble, solid wood plywood floor, etc.), and the temperature of the heating pipe is not higher than 60. The floor is heated to a certain temperature by the two-way circulation of special hot fluid in the pipe, and then a certain amount of heat is evenly radiated to the room by the floor to achieve the purpose of continuous indoor heating. Advantages of dry installation 1

In the underfloor heating system, if one of the pipes is damaged, it is also convenient to repair the pipes, without the steps of pipe clamps, cable ties and steel meshes. At the same time, there is no need for the curing period of cement, and the shelter period of construction workers can also be reduced from 7 days to 2 days. 2.

Most of the modules and pipes belong to plastics, and the coefficient of thermal expansion and cold contraction will be relatively similar, which better solves the problem of pipeline rupture and cement leveling layer cracking caused by heating and expansion of pipes. 3.The dry installation method is suitable for laying with and without keel, and can also lay wooden flooring directly on the module, and can achieve the purpose of health care through the module of far-infrared rays and magnetic therapy.

4.Dry installation is generally not used in the bathroom and kitchen. In addition, because the dry installation method has not been used in China for a long time, whether it can be suitable for the domestic climate and home decoration materials still needs us to go and observe it.

After the electric heating cable is energized, the working temperature is 40-60 degrees Celsius, and the heat dissipation surface is the ground (or wall, top surface).

Do the math how much it will cost you to renovate your home

1. Direct geothermal heating.

The extensive use of coal-fired boilers is an important cause of serious air pollution. At present, Beijing** has explicitly stipulated that coal-fired boilers will be abolished in major urban areas and replaced with oil or gas to reduce air pollution.

However, gas and fuel oil are expensive upfront and operating costs. The development of geothermal resources provides a feasible way to solve this problem. Vigorously advocating and promoting geothermal heating will make an important contribution to the cause of environmental protection.

2. Balneotherapy and health care.

The geothermal water in Beijing is a medium and low temperature thermal mineral water, which is rich in lithium, fluorine, radon, metaboric acid, metasilicic acid and other minerals, and has certain medical, health care and health preservation effects. Frequent bathing with hot mineral water has a certain effect on hypertension, coronary heart disease, cardiovascular and cerebrovascular diseases, rheumatism, ** diseases, etc. The introduction of hot mineral water into the house will undoubtedly greatly improve the quality of life of residents.

3. Entertainment and tourism.

Relying on hot spring bathing, a series of entertainment and tourism projects such as swimming pools, water parks, recreation centers, conference centers, recuperation centers, hot spring hotels, hot spring resorts, and high-end hotels can be developed.
