CN-121993871-A - Air conditioner heat storage defrosting method and device, medium and air conditioner

Abstract

The invention discloses a sample file management method, a sample file management device, a sample file management medium and an air conditioner, wherein the heat storage device is utilized to store heat in advance when a target heat storage condition is met, and after a defrosting mode is entered, the system still needs to draw heat from the indoor to melt a frost layer of an outdoor unit, but the indoor is compensated and regulated in real time by releasing the heat pre-stored in the heat storage device. The scheme effectively counteracts the temperature drop influence caused by indoor heat taking in the defrosting process, so that the indoor temperature is always maintained in a stable balance state in the defrosting period, and the problems that the room temperature severely fluctuates and the user thermal comfort is obviously reduced due to defrosting heat absorption of the traditional air conditioner are accurately solved.
