Principle of electromagnetic heating heating furnace
Introduction to frequency conversion electromagnetic heating furnace:
The electromagnetic heating furnace adopts the principle of electromagnetic induction heating, which uses AC rectification to convert it into DC power and then inverts it into a high-frequency alternating current, which acts on the inductor coil to generate an alternating magnetic field, so that the furnace body generates numerous small eddy currents, and the furnace is heated by eddy current collision. body, the water in the furnace body to achieve the purpose of heating, the coil has between water and thermally insulating material is greater than 20mm, but thermal efficiency can reach 98% environmentally safe, short warm-up time, fast heating. Biyuanda electromagnetic heating furnace system includes: variable frequency electromagnetic heating controller, intelligent operation control system, electromagnetic coil, heating furnace body and protection circuit.

9 , small size
The electromagnetic heating furnace is small in size and beautiful in appearance. It can be installed in the living room, bedroom, office and other places. Minimize the possession of space.
10 , a wide range of applications
Electromagnetic heating furnaces have a wide range of applications. They can be used for central heating or household heating. From residential quarters to self-built houses, from enterprises and institutions to ordinary shops, all places that require heating, such as hotels, schools, units, and houses, are involved.
Operating cost of electromagnetic induction heating furnace
Electromagnetic heating operation cost calculation
The electricity heating operation cost of one square meter in the whole heating period can be calculated according to the following formula:
Unit area heat load × heat load coefficient × daily working time × heating period days × electricity price unit price = heating cost per unit area of the entire heating period
Electromagnetic heating operation status can be divided into the following types:
( 1 ), the user is at home for a long time, the electric heating furnace is running 24 hours a day, in order to save operating costs, the heating temperature at night is appropriately lowered.
The cost of electromagnetic heating is: 0.05kw/m2×0.6×10 hours ×120 days ×0.52 yuan / degree= 18.72 yuan / M2
( 2 ), office workers, users only at noon, at home at night, electric heating furnace intermittent operation in 3 periods.
The electromagnetic heating cost is: 0.05kw/ M2 × 0.6 × 6 hours × 120 days × 0.52 yuan / degree = 11.23 yuan / M2
( 3 ), office, 5- day work system, heating only from Monday to Friday, electric heating stove running during the day, the rest of the time running in anti-freeze state.
The electromagnetic heating cost is: 0.06kw/ M2 × 0.6 × 6 hours × ( 120 days × 5 / 7 ) × 0.52 yuan / degree = 9.62 yuan / M2
( 4 ), the school, in addition to the five- day work week , there is a 35- day holiday, heating time is relatively short.
The electromagnetic heating cost is: 0.06kw/ M2 × 0.6 × 6 hours × [ ( 120 days - 35 days) ×5/7×0.52 yuan / degree = 6.81 yuan / M2
Using the above calculated value × actual heating area (saleable area) of the room, it is possible to calculate the operating cost of the entire heating period. If the user reasonably adjusts or closes the heating device that does not require a heating room (such as an unused room, bathroom or kitchen), the actual The heating area is reduced accordingly, and the heating costs are reduced accordingly.
Note: 0.07kw/ M2 is a standard energy-efficient building requiring winter heating electric load of 55 - 70w / M2 , electromagnetic heating is more than 35% energy saving than ordinary electric heating , 0.52 yuan / kW is the current unit price of electricity in Beijing. If the peak and valley electricity price can be calculated at an average of 0.35 yuan / kWh, the user's heating cost for a long time at home is 12.6 yuan, and the heat load coefficient of 0.6 means the initial period of the heating period. At the end of the period, the indoor heat load is small, and during the coldest period of the heating period, the indoor heat load is large, with an average of 0.6 . Actual heating area: The building area is multiplied by 0.78 , minus the practical area of the room without heating.
The electromagnetic heating furnace is similar to electric water heaters and air conditioners. The working time is proportional to the heat load demand of the room. The electricity price per unit, heating cycle and electric heating furnace work time are different in each region, such as the northeast region. The weather is cold, but his house insulation measures are better (the wall thickness is 0.5 meters, the external insulation material, the window is double-vacuum glass), and the electricity bill is relatively cheap.
