Embodiment Construction

[0033] When the multi-connected system is running in the heating mode, due to the thick suction pipe of the compressor, after the four-way reversing valve is reversed, the flow rate of the refrigerant entering the internal unit decreases, resulting in oil accumulation. Therefore, the air conditioner will automatically enter the oil return mode.

[0034] In order to make the above objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035]In the description of the present invention, it should be understood that the terms "first", "second", and "third" are only used for descriptive purposes, and should not be understood as indicating or implying relative importance or implicitly indicating the indicated The number of technical characteristics. Thus, features defined as "first", "second", and "third" may explic...

Abstract

The invention provides an air conditioner control method and device, an air conditioner and a storage medium and relates to the technical field of air conditioners. The control method comprises the steps of acquiring the current outdoor environmental temperature when receiving an instruction of the air conditioner operating in an oil return mode; determining the operating frequency of a compressorand the opening degree of an electronic expansion valve of an indoor unit according to the current outdoor environmental temperature; and correcting the operating frequency of the compressor according to the obtained high pressure. Compared with the prior art, the air conditioner control method has the advantages that reversing and oil return are carried out not through a four-way reversing valve, and the oil return purpose is achieved by correcting operating parameters of the compressor and the opening degree of the indoor electronic expansion valve; and the situation that the indoor temperature fluctuation is too large due to reversing and oil return and the comfort degree of users is affected is avoided.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner control method and device, an air conditioner and a storage medium. Background technique [0002] In the prior art, when the multi-split air conditioner is in heating operation, the refrigerant is turned into a gas by the high temperature and high pressure of the compressor in the compressor, and the refrigerant is discharged from the compressor, which will take away part of the lubricating oil, and the lubricating oil will be released along with the refrigerant. The circulating flow of the evaporator and condenser is stored in the evaporator and condenser, and the disadvantages are: the air conditioner does not return oil for a long time, and the oil stored in the evaporator or condenser will affect the heating effect of the air conditioner; Lack of lubricating oil over time leads to increased friction of bearings in the compressor and compres...
