Air duct heater power calculation: Accurate control of thermal energy output

Among many electric heating equipment, air duct heaters have been widely used in the industrial field due to their efficient and convenient characteristics.To ensure that the air duct heater can work stably and efficiently, the power calculation of the air duct heater is particularly important.Next, let’s learn how to calculate the power of the air duct heater.

Steps to calculate the power of the air duct heater

1. Determine the heating requirements: It is necessary to clarify the heating requirements of the air duct heater, including heating area, heating temperature, etc.

2. Calculate the thermal load: calculate the required thermal load based on the heating requirements.The calculation formula for thermal load is: thermal load (W) = heating area (m²) × heating temperature (℃) × thermal conductivity coefficient (W/m·℃).

3. Select the right heater power: Choose the right heater power according to the thermal load.The power of the heater should be about 1.2 times the heat load to ensure the heating effect.

Things to note when calculating the power of the air duct heater

• Thermal conductivity coefficient: Thermal conductivity coefficient is one of the key factors affecting the power calculation of air duct heaters.The thermal conductivity coefficients of different materials are different, and it needs to be selected according to actual conditions.

• Environmental factors: Ambient temperature, humidity, etc. will also affect the accuracy of the power calculation of air duct heater, and these factors need to be considered.

• Equipment efficiency: The efficiency of the heater will also affect power calculation, and the heater efficiency is generally above 90%.

When calculating the power of air duct heater, you can also refer to the following table to better understand the scope of application of air duct heaters of different power:

Heater power (kW)	Scope of application (m²)
1.5	10-15
3	20-30
5	40-50
7.5	60-80

The power calculation of air duct heater is crucial to ensure the equipment is stable and efficiently operated.When choosing a duct heater, be sure to calculate according to actual needs to avoid problems caused by excessive or too small power.
