This product has obtained the national patent and passed CCC certification of national compulsory product certification in China. At the same time, the perfect internal organizational structure, from management, production, sales, after-sales, so that you will never have worries.
Second, product introduction
"Delong" brand electromagnetic induction heating equipment is the replacement product of resistance heating equipment (electric boiler). The product patent is the shareholder of Delong Company. This product has been awarded the honorary titles of "China Quality Certification Association" and "Top Ten Best-selling Famous Brands".
Product heating principle:
The normal 50HZ power frequency power supply enters the heater and is output through the variable frequency power supply in the heater.
Part of it is a high-frequency power supply with 20000HZ frequency conversion. The heating core (as shown in figure 1) is separated from water and electricity, and high-frequency wires are wound inside and outside. The high-frequency current of high-frequency power supply generates high-frequency magnetic field through high-frequency wires, activates water molecules, and stimulates water molecules through infrared rays, thus achieving the purpose of rapid heating.
When the internal temperature of nonmetallic pipeline interlayer reaches above 27℃, infrared ray (as shown in figure 1) will help to heat the internal water.
Quiet and environmental protection: the normal audio frequency of human body is 15000- 18000HZ, and the working frequency of heater is 20000HZ, which exceeds the audio frequency of human body and has no noise when working.
Third, product features
1, high heat conversion efficiency and energy saving.
Technically, electromagnetic induction heating, infrared auxiliary heating and forced thermal convection are used to do work at the same time, which can quickly raise the room temperature and save energy. The equipment has no heat storage container, that is, it can be heated when it is added, and cold water enters and hot water exits, and the heat conversion efficiency is over 98%. At the same time, this product is equipped with electronic digital signal temperature sensor, microcomputer control, accurate and sensitive temperature control, so that the indoor temperature is balanced, thus saving electricity. Under the strong combination of electromagnetic induction heating and infrared auxiliary heating, it saves more than 30% energy than other fuel, gas and electric heating equipment.
2. Quiet and environmentally friendly
Electromagnetic induction heating is a green product with avant-garde flavor. It adopts advanced frequency conversion technology to convert 50HZ power frequency power supply into 20000HZ high frequency power supply, and there is no noise after the equipment is started. When in use, it does not release any harmful gas, is non-combustible, smokeless and tasteless, does not have many pollution problems of traditional heating equipment, and does not produce open flames when heating. In addition, hot water circulating heating is really environmentally friendly.
3, safe and reliable
The whole machine is separated from water and electricity, and the front circuit, the rear waterway and the heating core are operated by water and electricity. The product has constant power, weak current controls strong current, soft start and soft turn-off, no contact switch, no starting impulse current, and is safe and reliable to use.
4, long service life
The heating core part of this product is heated by electromagnetic induction, and the water is magnetized after heating, and no scale is formed. The system is maintenance-free for life, and the important components are imported from abroad, with a service life of more than 30 years.
5, the product is small in size
Beautiful appearance, can be placed in the living room, bedroom, office and so on.
6. Intelligent control
Microcomputer control, accurate to 65438 0 degrees. It can set 9 time periods every day, and can set indoor constant temperature, furnace constant temperature and various alarm functions. It is simple to operate, easy to learn and use.
7, the installation and operation costs are low.
After the successful development, the high-frequency electromagnetic induction heating heat source equipment quickly pushed to the market and won recognition, which shows its great advantages. Low long-term operation cost is its biggest advantage.
Four, three advantages
1, magnetized water
The heater is based on the principle of electromagnetic induction heating. Water and electricity are separated, and water molecules are activated and heated by magnetic field lines. When heating, the heating core part forms a large fixed magnetic field for water. After the water passes through, it is cut by the magnetic wire, which magnetizes the water and has no structure.
Advantages: long service life, stable thermal efficiency, and maintenance-free heater and whole HVAC system.
Why is there not a good structure?
(1) If the heater is structured, the heat will be conducted to the outside through the structural layer, which will affect the heating of water and reduce the thermal efficiency.
(2) If the radiator is constructed, it is equivalent to forming an insulation layer inside the radiator. The internal water temperature is 60℃ and the external radiator is 40℃, which affects the heating effect.
2. Soft start and soft shutdown without starting surge current
In your life, there is often a "click" when you turn on the refrigerator, TV and other electrical appliances, and the lighting equipment such as light bulbs darkens instantly when you use the water pump, which is caused by the voltage drop caused by surge current. The reason is that the rated current of 10A, for example, reaches 20A at the moment when the appliance is turned on, and then falls back to 10A. This 20A is the surge current, which affects the service life of other household appliances.
Electric heating products are very powerful appliances for users, and because of the temperature setting, they are frequently turned on and off every day in winter, which has a great influence on other household appliances. If the rated current of our heater is 20A, then it will be 5A, 6A, 10A, 15A, 20A, 1.2 seconds, and there is no surge current. Closing is also gradually closed within 1.2 seconds, which has no effect on household appliances.
3. Constant power
Current is directly proportional to voltage, electric power is the product of current and voltage (220V), and 380V is multiplied by root number 3, indicating that the power of electrical appliances varies with current and voltage.
The external voltage is unstable. 220V electricity may sometimes be 260V, and 380V electricity may sometimes be 420 or 340V V. If the voltage is high (current is proportional to voltage), the current will also rise and the power will be higher (current * voltage = power). The bearing capacity of the electrical components of the heater is certain, which will affect the service life of the heater. If the voltage drops, the power of the heater will be lower, which will affect the heating effect of users.
Our products can have constant power. By adjusting the frequency conversion pulse width, the current will automatically decrease when the voltage is high and increase when the voltage is low, so as to ensure the constant electric power, the service life of the heater and the heating effect of users.
