Abstract: A method and device are for adjusting air volume of an air conditioner are provided, that use a computer readable storage medium. The air conditioner includes an indoor unit with a vase-shaped housing, wherein the vase-shaped housing includes a bottle mouth and where an air outlet of the indoor unit is provided at the bottle mouth of the vase-shaped housing. A liftable cover plate is provided at the air outlet of the indoor unit. The method includes obtaining specified air volume, obtaining curved surface features of an inner wall at the bottle mouth of the vase-shaped housing and cover plate specifications of the cover plate, and adjusting an actual height of the cover plate according to the specified air volume, the curved surface features, and the cover plate specifications.

Abstract: A control method and system for refrigeration, oil return and noise reduction of a multi-split air-conditioner. The method comprises: when the accumulative time that the frequency of a compressor is smaller than the set frequency threshold reaches the oil return cycle and a standby indoor unit exists, conducting an oil return running mode; resetting the accumulative time; starting counting the oil return running time; calculating the indoor unit starting load; determining the opening degree of an expansion valve of the standby indoor unit according to the indoor unit starting load and whether there is anyone in a room where the standby indoor unit is located; controlling the compressor to run according to the set oil return frequency; and when the oil return running time reaches the oil return set time, exiting the oil return running mode, and conducting a normal refrigerating running mode.
