Abstract: Proposed by the present disclosure are an air conditioner, a control method and a computer-readable storage medium. The air conditioner includes: a refrigerant switching device, an indoor heat exchanger, an outdoor heat exchanger, a compressor, a memory, and a processor. The refrigerant switching device includes a liquid pipe, a gas pipe, and a valve assembly. The processor executes a computer program to execute the following: obtaining switching information of a working mode of the air conditioner; and controlling the valve assembly according to the switching information and the gas pipe and the liquid pipe are closed according to the sequence of the gas pipe first and then the liquid pipe, and then opened according to the sequence of the gas pipe first and then the liquid pipe.

Abstract: A switching device for a multi-split air conditioner and a multi-split air conditioner having same. The switching device has a base, a drain tank, multiple damping pads, and multiple fixing members. The base has a bottom wall and side walls, the side walls surrounding the bottom wall and extending upward from the edge of the bottom wall. The drain tank is disposed in the base, and the bottom surface of the drain tank is vertically spaced apart from the bottom wall of the base. The multiple damping pads are disposed on the drain tank and arranged at intervals in the circumferential direction of the drain tank. The multiple fixing members are respectively disposed on the damping pads and are connected to the side walls of the base. The multiple fixing members are all spaced apart from the drain tank.
