Example Embodiment

[0020] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0021] In the following description, a lot of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features known in the art have not been described. The shutdown in the drawings refers to the air conditioner receiving a shutdown signal after pressing the remote control of the air conditioner; turning on refers to After pressing the remote control of the air conditioner, the air conditioner receives the start signal.

[0022] The air conditioner system structure of the present invention is as figure 1 As shown, the composition and structure are the same as the existing air conditio...

Abstract

The invention discloses an air conditioner capable of controlling transfer of a refrigerant and a control method of the air conditioner and belongs to the field of air conditioners. In the air conditioner, a four-way reversing valve having a stop function is used; during start and shutdown of the air conditioner, the transfer of the refrigerant can be actively controlled during the start and shutdown of the air conditioner by controlling closing and opening of an electronic expansion valve, controlling start and stop of a compressor and controlling the switching of modes of the four-way reversing valve, so that the air discharging speed and the cooling speed when the air conditioner is started in a refrigeration mode can be effectively increased, and energy conservation is realized.

Description

technical field [0001] The invention belongs to the field of air conditioners, and in particular relates to an air conditioner with the function of controlling refrigerant migration and a control method. technical background [0002] After the current air conditioner is turned off in the cooling mode, the compressor stops working immediately, while the throttle valve keeps a certain opening, and the refrigerant will migrate from the condenser with higher pressure to the high-pressure In the lower evaporator, the refrigerant in the evaporator after shutdown is greater than the refrigerant in the evaporator when the air conditioner is running stably, and the refrigerant in the condenser is smaller than the refrigerant in the condenser when the air conditioner is running stably. After the next start-up, the compressor will migrate a large amount of refrigerant in the evaporator to the condenser. [0003] The refrigerant quality change process in the air conditioner is as follo...
