Problems solved by technology

After the air conditioner is turned off, the refrigerant stops flowing in the pipeline. When the air conditioner restarts the cooling mode, it takes a while for the refrigerant to enter a stable refrigeration cycle. Before that, the cooling effect of the air conditioner was not ideal. Especially in the case of high indoor temperature, it is difficult to reduce the indoor temperature quickly even if the heat exchange air volume is increased, and the user experience is poor

Abstract

The method comprises the steps that when the air conditioner is switched to a refrigeration mode, the air conditioner is controlled to operate in a first refrigeration control mode, in the operation process of the first refrigeration control mode, a first electromagnetic valve is in a closed state, and a second electromagnetic valve is in an open state; and a refrigerant output by the outdoor heat exchanger flows through the cold accumulation module through a second refrigerant pipeline to absorb the cooling capacity of the cold accumulation module and then is input into the indoor heat exchanger. The cold energy is stored in advance through the cold accumulation module, when the air conditioner is switched to the refrigeration mode, a refrigerant output by the outdoor heat exchanger enters the cold accumulation module through the second refrigerant pipeline to achieve secondary supercooling, the actual temperature of the refrigerant is further reduced, the refrigerating capacity of the refrigerant per unit mass is increased, and the refrigeration effect can be effectively improved after the refrigerant enters the indoor heat exchanger; rapid refrigeration is realized under the condition that the air conditioner restarts the refrigeration mode, so that a user can feel a cooling effect more pleasantly, and the user experience is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioner control, and in particular, to an air conditioner control method, a control device and an air conditioner. Background technique [0002] In the cooling mode of the air conditioner, the high-temperature refrigerant is compressed by the compressor and then enters the heat exchanger, and the low-temperature refrigerant obtained by exchanging heat between the heat exchanger and the outdoor enters the indoor heat exchanger to cool the air blown out of the indoor heat exchanger. achieve refrigeration. After the air conditioner is turned off, the refrigerant stops flowing in the pipeline. When the air conditioner restarts the cooling mode, it takes a period of time for the refrigerant to enter a stable refrigeration cycle. Before that, the cooling effect of the air conditioner is not ideal. Especially when the indoor temperature is high, even if the heat exchange air volume is increased,...
