Heating knowledge and common sense

1. What is the heating knowledge and common sense?

1. Heating refers to supplying heat to buildings and maintaining a certain indoor temperature. It solves the basic living needs of residents in northern my country for heating in winter. social services.

2. Central heating is a clean and guaranteed heating method that the heating group transports municipal heat to users' homes through pipelines. 3. Floor radiant heating is provided by various methods such as household gas heating furnaces, municipal heat pipe networks, and community boiler rooms.

This heating method has a uniform temperature and is more energy-saving, but it has higher requirements for pipe materials and will deform the furniture over time. 4. Gas heating uses natural gas, liquefied petroleum gas, coal gas, and electricity as energy sources. The heating time can be set by oneself and measured by households, but there are safety risks.

5. The heating area using gas, oil, and electricity as heating energy is increasing year by year, and is accepted by more and more people. Heating energy composed of coal, gas, oil, electricity, etc. The structure is becoming more reasonable, and heating charges are becoming increasingly market-oriented. In some areas, pilot communities that charge based on heat consumption have emerged. Extended information Heating methods of heating: 1. Water heating uses wall-mounted boilers or boilers to heat circulating water, and then connects it to the radiator through pipes. Finally, the appropriate temperature is output through the radiator to form an indoor temperature difference. Finally, thermal circulation is performed to increase the temperature of the entire indoor room. Rise evenly.

2. Heating heats the air. As soon as the cold air comes in, it is heated by the radiator into hot air. The hot air rises and forms convection with the cold air in the room. The cold air circulates to the vicinity of the heater and is heated into Hot air, hot air circulates in the room, and the room becomes warm. Baidu Encyclopedia-Heating.

2. Knowledge about heating

If you want to know about heating, let me tell you about radiators.

1. The valves on the heating pipes cannot be opened and closed at will. When the heating system is put into operation for the first time, it generally needs to be debugged.

Specific to each household, it is to adjust the valve of each standpipe to the appropriate position, open the manual air release valve of each radiator, discharge the air collected in the radiator, or open the The exhaust valve of the gas collecting tank on the top of the system is exhausted until each radiator is heated up, and the debugging is completed. Once commissioning is completed, the valve should be fixed and cannot be opened or closed at will.

2. Try to maintain a certain amount of heat dissipation space near the radiator in the room. Do not pile debris on or in front of the radiator.

Otherwise, the heat dissipation effect of the radiator will be affected. 3. The position of the radiator cannot be changed at will.

The installation of radiators is arranged in a position conducive to indoor heating, which can ensure that the air convection and indoor temperature are relatively uniform in various places. Once the position is changed, it will cause an imbalance in the indoor temperature. On the other hand, once the pipes and radiators are moved, leaks will easily occur, causing unnecessary losses to the home.

4. Do not release water from the system at will. If there is a lack of hot water in the pipes, cold water must be added to maintain a certain pressure in the pipe network system. The more hot water is lost, the water temperature in the pipe network will drop rapidly. , causing the indoor temperature to drop. Friends who use steel heaters should pay attention to closing the valve in time when heating is stopped so that the heater is filled with water. This can extend the practical life. Copper-aluminum composite radiators can also be filled with water if conditions permit! Generally, the service life of steel radiators is more than ten years, and if properly maintained, they can last for twenty years.

Copper-aluminum composite radiators last longer and can have a lifespan of more than twenty years. When choosing a home heater, you need to pay attention to the quality of the product, pay attention to the construction when installing it, and pay attention to maintenance when using it to ensure that the service life of the home heater will be longer.

3. What are the basic common sense of low-temperature radiant heating?

The heat dissipation surface of low-temperature radiant heating is integrated with the building components. It is divided into ceiling type and floor type according to its installation position. , wall type, skirting board type, etc., according to their structure, they are divided into pipe type, duct type, and combined type.

Low-temperature hot water floor radiant heating has the characteristics of high comfort, energy saving, convenient implementation of household heat metering, and convenient secondary decoration for residents. It can also effectively utilize low-temperature heat sources such as solar energy, underground hot water, and heating. and return water of air conditioning systems, heat pump hot and cold water units, industrial and urban waste heat and waste heat, etc.

Low-temperature radiant heating - low-temperature hot water floor radiant heating. Before the construction of low-temperature hot water floor radiant heating, low-temperature hot water floor radiant heating was used as the heating medium. Low-temperature hot water less than 60 degrees was used as the heating medium. Plastic pipes were used to be embedded in the ground and should not be less than 30mm in the concrete cushion. The ground structure was generally composed of It consists of structural layer (floor or soil), insulation layer (the upper part is laid with heating pipes with fixed spacing), filling layer, waterproof layer, moisture-proof layer and floor layer.

4. What is the introductory knowledge of home heating?

After entering winter, major cities in the north have now entered the heating period, and many families have also gone to various places. You can buy various heating equipment in large shopping malls, but what is the working principle of home heating equipment? Home heating means that it starts and ends at the same time on a household basis, which is different from central heating.

Home heating, and integrated heating using gas as heat source. Floor heating uses the entire ground as a radiator, and heats the entire ground evenly through the heat medium in the radiant layer of the floor. It uses the ground's own heat storage and the law of upward radiation of heat to conduct from bottom to top to achieve the purpose of heating.

Radiant floor heating is an advanced heating method. The principle is to pass circulating hot water into the heating pipe loop under the floor or floor tiles or directly lay heating cables to heat the floor. The heat passes through a large area of ??the ground and is mainly radiated to the space above the floor gently and evenly. Disperse, making the human body feel the dual thermal effects of heat exposure and air temperature.

Low-temperature floor radiant heating is to lay pipes under the ground indoors. The ground is heated to a certain temperature through hot water circulation in the pipes, and then the ground radiates heat evenly to the room. At the same time, the proportion of hot and cold air increases Under the action of the difference, the natural convection phenomenon of the air is generated, thereby creating an indoor thermal microclimate with ideal temperature distribution, making the indoor environment reach the most comfortable state for human body senses. So what are the benefits of floor heating to the human body? It improves blood circulation and metabolism and has obvious curative effect on rheumatism; the windless floor heating can reduce the cardiovascular pressure on the elderly; it maintains skin moisture and helps women stay youthful; there is no dust in the room, suitable for people with sensitive respiratory systems. , reduce the incidence of asthma; help keep the mind clear, help improve memory and understanding, thereby improving learning efficiency; improve sleep quality, fall asleep quickly, ensure deep sleep, help maintain strong work energy; save space, avoid installing traditional Direct hidden dangers caused by radiators. According to relevant scientific statistics, the floor heating system can encourage people to increase the amount of exercise and contribute to physical and mental health.

5. What are the common sense about heating safety in winter?

Common sense about heating safety in winter—ventilation and moisturizing are equally important. In winter, people are often most concerned about indoor temperature, but not about indoor air humidity. Not that concerned.

In fact, if the room temperature is too high and the humidity is too low, it will make people feel uncomfortable, and may even lead to symptoms such as chapped lips, bleeding nostrils, dry and itchy throats, etc.; experts from Comfort 100 Network said that for those who have heated the room, For families, the most important thing is to pay attention to indoor moisture. If the relative humidity is low, you can sprinkle some water on the ground or mop the floor with a wet mop to increase the humidity. You can also place a basin of water near the cooling facility to allow the water to slowly evaporate to keep the indoor air moist.

In addition, if you raise a few pots of flowers and plants in the room, it will not only adjust the relative humidity in the room, but also make the room full of greenery. Households with humidifiers should pay attention to regular indoor humidity adjustment to fully serve your health.

6. What knowledge is needed for heating operation management?

7. Heating tips: Why the heating is not hot

1. To stop heating in a wide range, first ask the neighbors on the left and right if the situation is the same, and secondly find out the reason and determine the user Check whether the indoor heating facilities are faulty, and then ask the unit or community heating station whether there is a power or water outage, whether the heat source or heating station equipment is faulty, and whether the heating main network is faulty, and then repair and solve it according to the corresponding situation.

2. The indoor heating part is not hot. This situation generally has the following reasons: ⑴ Air accumulation, blockage or unreasonable installation. If there is air accumulation in the radiator or at the end of the pipeline, contact the maintenance personnel of the heating station to come and debug the exhaust. If the problem cannot be solved after debugging, then the radiator or pipeline may be blocked or seriously installed unreasonably. For blockages or unreasonable installation, please ask professional maintenance personnel to conduct disassembly and inspection to eliminate the blockage or reinstall the pipes with reasonable installation. ⑵Hydraulic imbalance. This situation often occurs in a one-household, one-circulation installation system. Some radiators are not hot. If the hot ones are turned off, the non-hot ones can be heated up. This phenomenon is called hydraulic imbalance of the indoor circulation system. To deal with this situation, you can adjust the indoor system, turn off the hot heater first, let the tepid heater heat up, and then slowly turn on the hot heater.

3. Install or modify radiators without permission. The installation of radiators has strict technical requirements and must be installed under the windows. This can prevent the rising hot air flow and directly heat the cold air that penetrates through the window gaps. Airflow makes the air flowing through the room warmer and more comfortable. Users install or modify radiators themselves. Due to irregular installation, unreasonable position, and many bends, the heating air is blocked and the water flow resistance is too large. Not only does the heating in their own homes not get hot, but it also affects the connection of the same pipes up and down the entire building. All heaters are not hot. After heating is completed, professional technicians must be found for modification.

4. The poor quality of radiators affects the heat dissipation effect. The steam radiators installed in the homes of early centralized heating users do not meet the requirements of the current water circulation system. Some users purchase radiators in pursuit of aesthetics and ignore the radiators. Due to the uneven heating of these radiators, poor thermal conductivity, and easy to cause blockage, affecting the heating effect. It is recommended to find professional technicians to replace the radiator with good thermal conductivity.

5. The heating facilities are aging and the pipe network radiators have a limited service life. If users fail to maintain them on time, they will cause serious internal corrosion, scaling, and blockage, which will affect the heat dissipation effect. According to the "Qingdao Heating Regulations", the responsibility for the maintenance, repair, and update of the heat metering devices used by residential users or the heating facilities within the household port shall be borne by the user. Therefore, the user must do a good job in the maintenance of the heating facilities in daily life. If problems are discovered, ask professionals to flush or replace the heating facilities in a timely manner.

8. Heating installation knowledge and precautions

How to choose a radiator? How to choose a radiator for home decoration, and how to choose what kind of heating system the radiator is used for. If the home is used for central heating, the horizontal radiator should be installed under the window to block the intrusion of cold air. If the vertical radiator is chosen, it should be installed on both sides of the window. Since the radiator is close to the ground, it can keep all the indoor air. Convection occurs in the air, so the room temperature is maintained at equilibrium. How to choose a radiator for gas boiler systems and pressureless systems. For pressureless coal-fired heating systems, the height of the radiator should not exceed 1500. It is best to choose a radiator with a height of about 600 for the best effect. In this way, the water flows quickly and the radiator Good heat dissipation effect. The height of the gas boiler system should not exceed 1800. If the water temperature is high, you can consider a radiator with a small water capacity. If the water temperature is lower than 60 degrees, it should be made of steel, so that as long as the water temperature is high, the heat can be dissipated.

Heating (i.e. radiator) renovation is very critical. If the renovation is not done well, all the decorations in the home will be destroyed, so be sure to choose a professional renovation team and products with guaranteed quality. When buying a heater, you first need to look at the quality of the heater itself. Another thing you must look at is how strong is the heating manufacturer of this brand? Because heating products are different from other products, you can’t just buy it and be done with it. Buying a heater also involves several years of use, accident liability, and even compensation.

Therefore, you must choose a strong manufacturer and a big brand. This way, your home won’t be in trouble and you won’t be able to find a merchant in a few years. And generally big brand manufacturers are more afraid of heating leaks than consumers, because such big brands can really run away like monks, but they can never escape responsibility.
