[0049] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0050] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0051] See also Figure 1The present invention provides a method for controlling an air-conditioning system, the method comprising:

[0052] S10, obtaining the storage mode of the storage box;

[0053] S20, obtaining a temperature control mode of the air conditioning system;

[0054] S30: Controlling the opening and closing of the first air outlet and the second air outlet respectively according to the storage mode and the temperature control mode.

[0055] In the control method of the air-conditioning system provided by the present invention, the storage cavity is used to place food. Different storage modes are selected according to the type and requirements of the food. After selecting the storage mode, the temperature control mode of the air-conditioning system is detected. The air outlet temperatures of the outdoor unit and the indoor unit are exactly opposite. In order to maintain the set temperature in the storage cavity in any mode, the first air outlet and the second air outlet are selected to be opened according to the temperature control mode, so that the temperature of the storage cavity can be regulated regardless of the temperature control mode of the air-conditioning system.

[0056] Specifically, in this embodiment, the storage mode includes a fresh-keeping mode, and the temperature control mode includes a cooling mode and a heating mode;

[0057] When the storage mode is the fresh-keeping mode, step S30 includes:

[0058] S31. When the temperature control mode is the cooling mode, control the first air outlet to be open and the second air outlet to be closed;

[0059] In the preservation mode, it is only necessary to let cold air into the storage cavity. In the cooling mode, the indoor unit will blow out cold air and the outdoor unit will blow out hot air. Therefore, in this embodiment, the first air outlet is opened and the second air outlet is closed to let cold air into the storage cavity.

[0060] S32. When the temperature control mode is the heating mode, control the first air outlet to be closed and the second air outlet to be opened.

[0061] Similarly, in this embodiment, in the heating mode, the outdoor unit will generate cold air, so the second air outlet is directed to the storage cavity to generate cold air.

[0062] In addition, the storage mode includes a heat preservation mode, and the temperature control mode includes a cooling mode and a heating mode;

[0063] When the storage mode is the keep warm mode, step S30 includes:

[0064] When the temperature control mode is the cooling mode, the first air outlet is controlled to be closed and the second air outlet is controlled to be opened;

[0065] In the insulation mode, the temperature of the food in the storage cavity needs to be maintained. In the cooling mode, the first air outlet blows out cold air and the second air outlet blows out hot air. Therefore, in this embodiment, the second air outlet is connected to the storage cavity to keep the food warm.

[0066] When the temperature control mode is the heating mode, the first air outlet is controlled to be opened and the second air outlet is controlled to be closed.

[0067] Similarly, in the heat preservation mode, when the indoor unit generates hot air, the hot air is directly injected into the storage cavity through the first air outlet to maintain the temperature of the food in the storage cavity.

[0068] In one embodiment provided by the present invention, the objects to be stored are placed in the storage cavity, and the fresh-keeping mode or the heat-keeping mode is selected according to the state of the storage cavity. In the fresh-keeping mode, cold air is passed into the storage cavity. At this time, the storage cavity is ventilated according to the respective air outlet temperatures of the indoor unit and the outdoor unit; in the heat-keeping mode, hot air is passed into the storage cavity. Similarly, the gas of the part of the indoor unit or the outdoor unit that generates hot air is selected to be introduced into the storage cavity.

[0069] On the other hand, the control method of the air-conditioning system further includes:

[0070] S01, obtaining the set temperature difference;

[0071] S02. Controlling the opening and closing states of the cabinet air vents according to the relationship between the set temperature difference and the preset range.

[0072] The cabinet is provided with a cabinet air vent to blow air onto the kitchen countertop. In this embodiment, by obtaining the set temperature difference and based on the relationship with the preset range, it is determined whether the inside of the cabinet has met the preset temperature conditions, and then it is determined whether there is excess wind to blow out.

[0073] Specifically, step S02 includes:

[0074] S021. When the set temperature difference is greater than the preset range, controlling the cabinet air vent to close;

[0075] When the set temperature difference is greater than the preset range, it proves that there is still a large temperature difference between the set temperature values inside the cabinet. At this time, it is necessary to give priority to adjusting the temperature inside the cabinet to the set temperature. Therefore, the cabinet air vents are not opened to insulate the cabinet, so that the internal temperature can quickly reach the set temperature value.

[0076] S022. When the set temperature difference is not greater than the preset range, control the cabinet air vents to be at least partially open.

[0077] When the set temperature difference is not greater than the preset temperature, it proves that the temperature inside the cabinet is close to the preset temperature. At this time, there will be excess wind blowing on the external table, thereby controlling the cabinet air outlet to be at least partially open.

[0078] It should be noted that the cabinet air vents are controlled to be at least partially open according to the size of the preset temperature difference. The smaller the preset temperature difference, the larger the air vents are opened.

[0079] Specifically, in this embodiment, step S022 includes:

[0080] S0221. When the set temperature difference is within the preset range, controlling one of the upwind vent and the downwind vent to be opened and the other to be closed according to the temperature control mode of the air conditioning system;

[0081] The cabinet air vents include upper air vents and lower air vents that are spaced apart from each other. In this embodiment, when the set temperature difference is within the preset range, it proves that there is excess wind in the cabinet to be transported outward without affecting the temperature control inside the cabinet. At this time, choose to open the upper air vent or the lower air vent.

[0082] It should be noted that, in this embodiment, step S0221 includes:

[0083] When the temperature control mode is the cooling mode, the upper air vent is opened and the lower air vent is closed;

[0084] When the temperature control mode is the heating mode, the downwind vent is opened and the upwind vent is closed.

[0085] In this embodiment, according to the law that cold air sinks and hot air floats, when cooling, the upper air vent is opened, so that after the internal temperature of the cabinet remains stable, excess cold air accumulates and overflows from the top, while ensuring the internal temperature and transferring the temperature to the outside; similarly, when heating, the lower air vent is opened.

[0086] S0222. When the set temperature difference is less than the preset range, control the upwind vent and the downwind vent to open simultaneously.

[0087] When the set temperature difference is smaller than the preset range, it proves that the temperature control inside the cabinet is almost complete. At this time, the air-conditioning system can fully take into account the surrounding environment and open all the upwind vents and the downwind vents to diffuse the temperature to the surrounding environment.

[0088] In one embodiment provided by the present invention, a set difference between the set temperature and the actual temperature is obtained. When the set difference is within the preset range, the air conditioning system opens the upper air vent during cooling and opens the lower air vent during heating; when the set difference is greater than the preset range, the upper air vent and the lower air vent are closed to keep warm; when the set difference is less than the preset range, the upper air vent and the lower air vent are all opened.

[0089] On the other hand, the control method of the air conditioning system also includes:

[0090] S03, obtaining the set temperature difference;

[0091] S04. Controlling the operating frequency and the operating wind speed of the indoor unit according to the relationship between the set temperature difference and the preset range.

[0092] In this embodiment, the operating frequency and the operating wind speed of the air-conditioning system are automatically adjusted according to the set temperature difference, so as to automatically control the temperature inside the cabinet.

[0093] Specifically, in one embodiment provided by the present invention, when the set temperature is within the preset range, it proves that the temperature inside the cabinet is close to the set temperature. At this time, the medium frequency operating frequency and the medium air outlet speed are selected; when the set temperature is greater than the preset range, it proves that the temperature inside the cabinet needs to be quickly controlled. At this time, high frequency operation and high air outlet speed are selected; and when it is less than the preset range, low frequency operation and low air outlet speed are selected.

[0094] The operating frequency is the compressor frequency, and the frequency increases from the low-frequency operating frequency to the high-frequency operating frequency; and the air outlet speed increases from the low air outlet speed to the high air outlet speed.
