Abstract
Provided are a control method for a heating unit, the heating unit, and a refrigerating and freezing apparatus. The control method includes: acquiring a forward power signal output from an electromagnetic wave generation module and a reverse power signal returned to the electromagnetic wave generation module; calculating an electromagnetic wave absorption rate of an item to be treated according to the forward power signal and the reverse power signal; and adjusting a rotation speed of a cooling fan according to a power value of the forward power signal and the electromagnetic wave absorption rate. There is no need to dispose additional temperature sensing apparatuses, heat generated by the electromagnetic wave generation module can be reflected more precisely, and unexpected energy waste and noise pollution are avoided while fully cooling the electromagnetic wave generation module.
