1. Electric heating design and calculation occupy a very important position in the electric heating system. This chapter briefly introduces some calculations and designs in typical applications. For further study, please refer to relevant manuals. The design and calculation of electric heating are usually carried out in the following three parts:
1. Calculate the power required to heat from the initial state to the set temperature within the specified time.
