Abstract: The present invention belongs to the technical field of air conditioners, and aims to solve the problem of not being conducive to energy saving because the control logic of using a compressor to perform up-frequency heating is independent from the control logic of using an electric heating device to perform heating when an existing variable-frequency air conditioner can normally perform heating. Therefore, provided is a heating control method for a variable-frequency air conditioner. The variable-frequency air conditioner comprises an indoor unit, a compressor and an electric heating device, wherein the electric heating device is arranged on the indoor unit and can heat air output from the indoor unit. The heating control method comprises: acquiring an up-frequency power of a variable-frequency air conditioner; if the up-frequency power of the variable-frequency air conditioner is greater than or equal to a preset power, maintaining the current operating frequency of a compressor and starting an electric heating device; and if the up-frequency power of the variable-frequency air conditioner is smaller than the preset power, continuously increasing the operating frequency of the compressor. In the present invention, when an variable-frequency air conditioner normally performs heating, heating can be performed in a power-saving mode, thereby achieving energy saving and being environmentally friendly, and improving the user experience.
