Defrosting control method and related equipment

The embodiment of the invention provides a defrosting control method and related equipment. The defrosting control method is used in the air cooling unit, the air cooling unit comprises a first system and a second system, the first system and the second system share one fin, the defrosting mode is determined by estimating the defrosting point time, whether the two systems need to conduct defrosting at the same time or only the first system conducts defrosting is needed, and the appropriate defrosting mode is selected. The problems that under the condition that an existing mode is single, the indoor temperature change is large due to simultaneous defrosting, and the time is long due to alternate defrosting are solved. Meanwhile, if only the first system carries out defrosting, the second system stops using the fins shared with the first system, so that the defrosting efficiency and the defrosting effect of the first system are guaranteed, the influence of heat absorption of the system which does not carry out defrosting in the alternate defrosting mode on defrosting is avoided, the problem of long time caused by alternate defrosting is also solved, and the defrosting efficiency is improved. And the problem that the user experience is influenced by the existing defrosting mode is solved.
