Abstract: A method and a device for controlling a capacity change of a compressor, and a smart home appliance. The method includes: determining whether a capacity of the compressor is required to be changed; if yes, determining an intermediate frequency; changing the capacity of the compressor while maintaining the operating frequency of the compressor at the intermediate frequency; and the maintaining the operating frequency of the compressor at the intermediate frequency reduces a sudden change in output of the compressor after the changing the capacity.

Abstract: The present disclosure relates to an embedded type air conditioner outdoor unit and an air conditioner. The embedded type air conditioner outdoor unit comprises: a housing comprising an air inlet and an air outlet which are provided on the same side surface of the housing; a heat exchanger provided within the housing, for heat exchange with air introduced by the air inlet; and a cross-flow fan provided within the housing, for flowing the air introduced by the air inlet through the heat exchanger. By applying the technical solution of the present application, the air introduced by the air inlet after heat exchange by the heat exchanger is expelled via an exhaust port by using the cross-flow fan, thereby improving the problem of much noise of the embedded type air conditioner outdoor unit.

Abstract: A method for controlling the power-on or power-off of an air conditioner is provided. The method includes the following steps: determining whether a variable capacity compressor of the air conditioner is in a standby single-cylinder operation state before starting the air conditioner, where the variable capacity compressor is configured to be switchable between a single-cylinder operation state and a dual-cylinder operation state; if so, starting the air conditioner; if not, switching the variable capacity compressor to the standby single-cylinder operation state, and then starting the air conditioner. With this control method, regardless of whether the air conditioner is shut down because the power supply of the unit is cut off or because a power-off signal is received, the air conditioner can be started in a single-cylinder operation state in the next startup, so that the operation state of the cylinder is always determined when starting the air conditioner.
