Calculation of electric heaters: precise control, efficient and energy-saving

Among many industrial equipment, electric heaters are widely used in all walks of life due to their efficient and convenient characteristics.How to calculate the electric heater to ensure its stable operation, energy saving and efficient operation has become the focus of many users.Today, let’s discuss the calculation method of electric heaters together.

1. Basic principles of electric heaters

The electric heater converts electrical energy into heat energy to heat the equipment.The basic principle is: when current passes through the heating element, due to the existence of resistors, the electrical energy is converted into thermal energy, thereby achieving heating of the equipment.

2. Calculation method of electric heater

1. Power calculation: The power of an electric heater refers to the rate at which electric energy is converted into heat energy per unit time.The calculation formula is: Power (W) = Voltage (V) × Current (A).

2. Calculation of heating area: The heating area refers to the actual heating area of the electric heater.The calculation formula is: heating area (m²) = heating length (m) × heating width (m).

3. Calculation of heating time: The heating time refers to the time required for the electric heater to heat to the set temperature.The calculation formula is: heating time (h) = heating quantity (J) ÷ heating power (W).

3. Precautions for purchasing electric heaters

1. Power selection: Choose the appropriate power according to actual needs to avoid excessive power causing energy waste, or too small power cannot meet heating needs.

2. Heating element material: Choose high temperature and corrosion resistant heating elements to ensure the service life of the electric heater.

3. Protection level: Choose the appropriate protection level according to the use environment to ensure that the electric heater operates normally in harsh environments.
