Can electric heating radiate? Many people choose electric heating in winter. Electric heating can make the room warmer. Some people want to know whether there is radiation in electric heating and whether it will harm their health. The following is an explanation about whether the electric heater has radiation!
Does the electric heater radiate? 1 the answer is yes, because any electrical appliance will have more or less radiation. Although the household electric heater can radiate, the radiation amount is very small, which is within the range of human safety.
Some netizens believe that electric heaters such as electric heaters radiate infrared rays. Strictly speaking, there is electromagnetic radiation around us. Household electric heating equipment uses 50HZ power frequency alternating current, so it is absolutely impossible to emit high-frequency electromagnetic waves harmful to people.
Electric heater is a very convenient heating equipment. The principle of heat dissipation is to directly heat the indoor air by using the radiation diffusion or convection heat transfer principle of outdoor materials to achieve the purpose of raising the room temperature. Therefore, radiation is inevitable, mainly because it is big or small.
There are many kinds of household electric heaters. Some greenhouses can adopt reflective type, all greenhouses can adopt convection type to warm every corner of the room through natural convection of air, and there is also a fan type that uses fan motor to force convection to warm the air. Different types of electric heaters have different radiation levels.
What kind of electric heating is good?
Choose the right one, not the expensive one.
This can't be decided only by looking at one aspect of electric heating. Maybe you have the best electric heating in your home, the space is not suitable, and it is not the best for you.
Generally speaking, the choice of electric heating depends on the size of the room. If the room is not warm, it is necessary to choose a slightly larger power, and the room area is more than 20 square meters. It is more suitable to buy an electric heater with a ratio of 1500W or even1000 w.
Finally, I would like to remind you that all electrical appliances have radiation, and the best way to avoid radiation is actually to reduce the use of these electrical appliances. Of course, if you have to use it, you'd better choose one with relatively small radiation, so as to minimize the damage.
Does the electric heater radiate? Many people will ask, "Does the electric heater radiate?" Every year, especially for families with old people and children. Before answering this question, we must understand that any electric heating equipment, as long as it is an electrical appliance, will inevitably have radiation.
Strictly speaking, there is no electrical appliance without radiation on the market. Electromagnetic radiation is everywhere around us, because the radio can receive radio stations anywhere.
While electric heating uses the principle of radiation diffusion or convection heat transfer of external materials to dissipate heat, that is, electric energy is converted into heat energy, so radiation is inevitable, mainly because it is a big or small problem.
Different types of electric heaters have different radiation levels. When choosing electric heating products, users can choose a product with the least radiation or water heating equipment.
Such as radiator or floor heating, can be used in conjunction with wall-hung boilers, and hot water is taken from pipelines, so that the heating comfort is high, and the demand for hot water in family life can also be met. Below, we take electric floor heating and liquid circulation system as examples to compare the advantages and disadvantages of electric heating and water heating.
We often say that there are two main forms of floor heating: electric floor heating and circulating system. As the name implies, electric floor heating is converted into heat energy by electric energy, while liquid circulation system heats the floor by burying hot water pipes in the floor and radiates heat evenly to the room.
Both of them belong to comfortable heating methods, but they are different in radiation problems, occupied floor height, operating costs and applicable units. , embodied in the following points:
1, the electric floor heating has radiation problems, and the circulating system has no radiation safety concerns;
2. The laying cost of electric floor heating is basically only related to the area, and it is convenient to lay in a small area. The circulatory system is suitable for large families;
3. The floor height occupied by electric floor heating is 2 cm less than that of the circulating system;
4. The liquid circulation system is comfortable, but the heat transfer speed is slower than that of electric floor heating;
5. The running cost of electric floor heating is relatively high, and the circulation system is comfortable and energy-saving;
6. The liquid circulation system can also solve the problem of domestic water consumption at the same time without another domestic water heater;
7. The service life of the circulating system is more than 50 years, which is longer than that of electric floor heating.
Advantages of energy-saving electric heater
1, high efficiency, energy saving and environmental protection
The electrothermal conversion rate of Planck carbon crystal wall heating parts is greater than 99. 8%, which is a commodity with electrothermal conversion rate on the market. The temperature rises quickly, saving energy and electricity, and the running cost is more wasteful than the traditional way. There is no harmful gas emission, no good dust purification, no air blockage and drying problems.
2. The temperature rises rapidly
The traditional heating rate is 2 hours, and Planck carbon crystal wall is used for heating. Under normal circumstances, 15 minutes can reach 18 degrees Celsius.
3. Comfortable heating
Average heating, average constant heat energy from bottom to top, fully meet the needs of human body. Show the concept of "warm feet and cool head" advocated by western medicine.
4, the structure is complex
The secondary components of Planck carbon crystal wall heating are carbon crystal heating plate, power supply connecting wire and temperature controller. The construction device is simple and convenient. No matter whether it is total heating or partial heating, there is no restriction on the design and auxiliary installation of components, and the design concept of "people-oriented" is completely achieved.
What are the types of electric heating?
1, oil-immersed electric heater
Oil-filled type, also known as oil-filled type, consists of sealed electric heating elements, metal radiating pipes or fins, indicator lights, etc. After the power supply is turned on, the heat transfer oil is heated and then convectively circulated along the radiator pipe or radiator.
Heat is dissipated through the surface of the cavity wall and plays a heating role. The advantage of this electric heater is that it will automatically cut off power when the temperature reaches the set temperature.
2, electric heating film electric heater
Electric heating film adopts transparent high-temperature electric heating film as heating material, and the heat transfer mode is enhanced convection, which has fast start-up speed and rapid temperature rise, but the temperature drops quickly after power failure. The electrothermal film has long service life, small size and beautiful appearance, and is a new type of heater product.
3. Convective electric heating
Convective electric heaters use heat energy to heat. After electrifying, the air around the heating element will be heated up, and will flow out from the air outlet, and then the cold space will be replenished to realize repeated circulating heating. The advantages of this electric heater are that it meets the comfort requirements of ergonomics, high safety performance and no noise interference.
4. Quartz tube electric heater
The quartz tube takes the timely radiation tube as the electric heating element, and uses the far infrared heating energy-saving technology to make the far infrared emitted by the far infrared radiation element be absorbed by the object and directly turned into heat energy, thus achieving the purpose of heating.
The quartz tube electric heater has the advantages of support, protection, heating, strong penetration, good heating direction, convenient movement and affordable price.
