Problems solved by technology

Before the air conditioner is started, the refrigerant storage on the outdoor side is relatively small and almost exists in gaseous form, while the refrigerant storage on the evaporator side is relatively large, so it takes a long time to re-establish the system balance, resulting in After the air conditioner is started, the temperature of the outlet air drops slowly

Embodiment 1

[0048] In the above embodiment, it is detected that the air conditioner is in the standby state, and the control and adjustment of the reversing assembly 40 to the first conduction state also includes: if it is detected that the reversing assembly 40 is in the first conduction state for a period greater than or equal to the duration Threshold value, control and adjust the reversing assembly 40 to the second conduction state, so as to close the flow path from the indoor heat exchanger 10 to the reversing assembly 40 .

[0049] In this embodiment, within the set duration threshold, the refrigerant from the side of the indoor heat exchanger 10 has flowed to the discharge end of the compressor 30, and it is enough to make the connection between the side of the outdoor heat exchanger 20 and the side of the indoor heat exchanger 10 The amount of refrigerant quickly reaches a balance. At this time, control and adjust the reversing assembly 40 to the second conduction state to close th...

Embodiment 2

[0051] Such as image 3 As shown, the difference from Embodiment 1 is that: on the basis of Embodiment 1, further, an auxiliary liquid storage tank 60 is connected in series on the flow path between the exhaust end of the compressor 30 and the reversing assembly 40 to assist The liquid storage tank 60 is used to store the refrigerant flowing to the exhaust end.

[0052] In this embodiment, by setting the auxiliary liquid storage tank 60 in series on the flow path between the discharge end of the compressor 30 and the reversing assembly 40, the auxiliary liquid storage tank 60 plays the role of storing refrigerant, improving the performance of the compressor 30. The amount of refrigerant stored at the exhaust end of the exhaust end ensures that when the reversing assembly 40 is controlled and adjusted to the second conduction state, enough refrigerant enters the outdoor heat exchanger 20 to increase the cooling speed of the air conditioner.

Embodiment 3

[0054] Such as image 3 As shown, the difference from Embodiment 2 is that: on the basis of Embodiment 2, further, a first control valve 70 is provided between the auxiliary liquid storage tank 60 and the reversing assembly 40 to respond to the operation command of the cooling mode , control and adjust the reversing assembly 40 to the first conduction state. In the first conduction state, the refrigerant placed in the indoor heat exchanger 10 can flow to the compressor 30 through the reversing assembly 40, specifically including: controlling the opening The first control valve 70 is used to guide the refrigerant in the indoor heat exchanger 10 into the auxiliary liquid storage tank 60 through the reversing assembly 40 in the first conduction state.

[0055] In this embodiment, by setting the first control valve 70 between the auxiliary liquid storage tank 60 and the reversing assembly 40, the first control valve 70 is used to control the disconnection of the flow path between ...

Abstract

The present invention provides an operation control method, an operation control device, an air conditioner, and a storage medium, wherein the operation control method includes: detecting that the air conditioner is in a standby state, controlling and adjusting the reversing assembly to a first conduction state, and at the first In the conduction state, the refrigerant placed in the indoor heat exchanger flows to the exhaust end of the compressor through the reversing component; in response to the operation command of the cooling mode, the air conditioner is controlled to operate in the cooling mode according to the operation command, and in the cooling mode Next, the control adjusts the reversing assembly to the second conduction state, and the compressor runs to drive the refrigerant at the discharge end to flow to the outdoor heat exchanger. Through the technical solution of the invention, it is beneficial to improve the refrigeration speed and achieve the purpose of rapid refrigeration.

Description

technical field [0001] The present invention relates to the technical field of air conditioner control, in particular to an operation control method, an operation control device, an air conditioner and a computer-readable storage medium. Background technique [0002] When the air conditioner reaches the cooling and stable operation state, the amount of refrigerant on the outdoor side is relatively large, while the amount of refrigerant on the indoor side is relatively small. Before the air conditioner is started, the refrigerant storage on the outdoor side is relatively small and almost exists in gaseous form, while the refrigerant storage on the evaporator side is relatively large, so it takes a long time to re-establish the system balance, resulting in After the air conditioner is started, the outlet air temperature drops slowly. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or rel...
