[0046] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0047] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0048] The main solution of the embodiment of the present application is: when the air conditioner meets the nighttime defrosting conditions, the water tank temperature of the hot water tank is obtained, and it is detected whether there is a user sleeping in the room corresponding to each indoor unit to obtain the user sleep detection result; and the air conditioner is controlled to perform nighttime defrosting according to the water tank temperature and the user sleep detection result.

[0049] In this embodiment, for the convenience of description, the following description is made by taking the identification of the air conditioner as the execution subject.

[0050] Since the outdoor unit of the prior art air conditioner is prone to frost after running at low temperature for a long time, the conventional air conditioner condenser will trigger the defrost action after frosting, that is, the four-way valve is switched to cooling, and the frost on the outdoor unit heat exchanger is melted by high temperature and high pressure refrigerant.

[0051] Conventional defrosting action is prone to cause abnormal noise. On the one hand, there is the abnormal noise caused by the switching of the four-way valve of the outdoor unit. On the other hand, the defrosting frequency is generally higher after switching to refrigeration, the refrigerant flow rate is large, and the system pressure is also higher when the indoor unit is not blowing air. The hissing sound of the refrigerant and the abnormal sound of the electronic expansion valve impacting the valve needle will be more obvious, affecting the user's experience during sleep at night.

[0052] This application provides a solution, which realizes analysis based on the user's sleep situation and the water tank temperature, and realizes defrosting of the outdoor unit and uninterrupted heating of the indoor unit through cooling of the water tank. Through sleep scene recognition, the defrosting operation noise is improved, and the user's sleep experience is improved.

[0053] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, an air conditioner, etc. The following takes an air conditioner as an example to illustrate this embodiment and the following embodiments.

[0054] Based on this, the embodiment of the present application provides an air conditioner control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the air conditioner control method of the present application.

[0055] In this embodiment, the air conditioner control method includes steps S10 to S40:

[0056] Step S10, when the air conditioner meets the night defrosting condition, the water tank temperature of the hot water tank is obtained, and it is detected whether there is a user sleeping in the room corresponding to each indoor unit, and the user sleeping detection result is obtained;

[0057] It should be noted that in the normal heating / hot water system of the heat recovery system, the outdoor heat exchanger acts as an evaporator, and the air conditioner indoor unit and water tank act as a condenser to achieve the heating and hot water functions. After long-term operation, the outdoor heat exchanger is prone to frost. The conventional defrost control system switches to the cooling + hot water mode, and the outdoor heat exchanger turns to the condensation side for defrosting.

[0058] It should be understood that the present invention proposes a nighttime defrost control method for a heat recovery system. During defrosting in a specific time period, the system will switch to water tank refrigeration to ensure that the air conditioner indoor unit can heat normally during the defrosting process. Through sleep scene recognition, the defrosting process ensures that when a person is detected sleeping, the corresponding indoor unit electronic expansion valve is closed to reduce defrosting noise and improve user experience. When the unit is running in a set time period (generally set by the user as sleep time), the outdoor unit condenser outlet temperature sensor T3 and the operating time are used to determine whether the unit needs to be defrosted. When defrosting is entered, the system switches to the heat recovery nighttime defrost mode, such as Figure 2 As shown. Explain the figure At this time, the water tank is converted to the evaporation side, and the outdoor unit and the air conditioner are the condensation side. On the one hand, the outdoor unit heat exchanger can quickly defrost through the high-temperature refrigerant, and on the other hand, it ensures the uninterrupted heating of the air conditioner, bringing improved user experience. The defrosting process will run a specific defrosting frequency to ensure the speed and effect of defrosting.

[0059] It should be noted that it is necessary to first determine whether the current operation of the air conditioner meets the night defrosting conditions, then directly measure the water tank temperature of the hot water tank, and monitor whether there is a user sleeping in the corresponding room of each indoor unit through infrared. In order to further improve the abnormal sound problem during the defrosting process, before entering the night defrosting program, each air conditioner indoor unit will detect the indoor scene through an infrared camera. When it is recognized that there is a user sleeping in the room, the electronic expansion valve of the indoor unit in the corresponding room will be temporarily closed during the defrosting process to prevent the defrosting frequency from suddenly increasing, causing the refrigerant flow sound to become louder, thereby affecting the user's sleep.

[0060] In a feasible implementation manner, in order to determine whether the air conditioner currently meets the night defrost conditions, before step S10, it also includes: obtaining a preset defrost time period, the condenser outlet temperature of the air conditioner outdoor unit and the accumulated running time of the air conditioner; and determining whether the air conditioner meets the night defrost conditions based on the preset defrost time period, the condenser outlet temperature and the accumulated running time.

[0061] It should be understood that when the unit is running in the set time period (generally set by the user as sleep time), the unit is judged whether it needs defrosting by the outdoor unit condenser outlet temperature sensor T3 and the running time. Among them, the preset defrosting time period is the preset user sleep time period, for example: 9 pm to 8 am the next day. The specific time period is not specifically limited and can be set by yourself.

[0062] In a feasible implementation manner, in order to perform defrost when the current moment is not in the sleep time period set by the user, the step of determining whether the air conditioner meets the night defrost conditions according to the preset defrost time period, the condenser outlet temperature and the accumulated running time also includes: when the preset defrost time period is not met at the current moment, detecting whether there is a user sleeping in the room corresponding to each indoor unit to obtain a user sleep detection result; and adjusting the air conditioner to the air conditioning refrigeration water tank hot water making mode for defrosting according to the user sleep detection result.

[0063] In a specific implementation, if the preset defrosting time period is not met at the current moment, the air conditioner is controlled to defrost in a conventional defrosting mode, and the user's sleep condition is detected at the same time, and the air conditioner is controlled to defrost in a refrigerated water tank hot water making mode according to the user's sleep condition. The electronic expansion valve is set according to the preset opening.

[0064] Step S20, controlling the air conditioner to perform nighttime defrosting according to the water tank temperature and the user sleep detection result.

[0065] It should be noted that when entering defrost mode, the system switches to heat recovery night defrost mode, such as Figure 2 As shown. At this time, the water tank is converted to the evaporation side, and the outdoor unit and the air conditioner are the condensation side. On the one hand, the outdoor unit heat exchanger can quickly defrost through the high-temperature refrigerant, and on the other hand, it ensures the uninterrupted heating of the air conditioner, bringing improved user experience. The defrosting process will run a specific defrosting frequency to ensure the speed and effect of defrosting.

[0066] It should be understood that the corresponding electronic expansion valve is adjusted according to the water tank temperature and whether a user is sleeping in the room corresponding to a certain air-conditioning indoor unit, so as to achieve air-conditioning defrosting without affecting the user's sleep.

[0067] In a feasible embodiment, in order to perform corresponding defrost control based on the water tank temperature, a water circuit electronic expansion valve is connected between the hot water module and the air-conditioning outdoor unit, and step S20 includes: when the water tank temperature is greater than or equal to the preset water tank temperature, closing the water circuit electronic expansion valve, and starting the water tank water circulation mode of the hot water tank to reduce the water tank temperature of the hot water tank until the water tank temperature is lower than the preset water tank temperature; and when the water tank temperature is lower than the preset water tank temperature, controlling the air conditioner to enter the night defrost mode for defrosting according to the user detection result.

[0068] In the specific implementation, during the heating process, the water temperature in the water tank may be heated to a relatively high temperature. At this time, if the system switches to the night defrost mode, the evaporation side pressure may be too high, which may cause the system to shut down due to excessive high pressure protection. Therefore, before entering the night defrost control, it is necessary to increase the judgment of the current water temperature condition.

[0069] It should be noted that if the water temperature Tw is lower than the set threshold value Tw_set and the defrosting conditions are met, the night defrosting mode can be directly entered according to the above logic.

[0070] It should be understood that if Figure 2 As shown in the figure, if the water temperature Tw is higher than the set threshold value Tw_set and the defrosting conditions are met, the defrosting entry time needs to be delayed. At this time, the water circuit electronic expansion valve EXV D is closed first to prevent the water tank from continuing to make hot water. At the same time, the water tank water circulation is turned on to quickly reduce the water temperature. After the water temperature drops below the threshold value Tw_set, the night defrosting mode is immediately entered. After the mode is switched, the water circuit electronic expansion valve is immediately opened and the circulating water pump is stopped to prevent the water temperature from being too low to affect the heat exchange effect.

[0071] This embodiment provides an air conditioner control method, when the air conditioner meets the night defrosting conditions, the water tank temperature of the water heating tank is obtained, and it is detected whether there is a user sleeping in the room corresponding to each indoor unit to obtain the user sleep detection result; and the air conditioner is controlled to perform night defrosting according to the water tank temperature and the user sleep detection result. In this way, it is realized to analyze the user's sleep situation in combination with the water tank temperature, and through the cooling of the water tank, the outdoor unit is defrosted while the indoor unit is continuously heated. Through the recognition of the sleep scene, the defrosting operation noise is improved, and the user's sleep experience is improved.

[0072] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 , step S20 includes steps S201 to S202:

[0073] Step S201, when the water tank temperature is lower than a preset water tank temperature, determining the indoor unit to be adjusted corresponding to the user's sleeping room according to the user detection result;

[0074] It should be noted that when it is determined that the water tank temperature is lower than the preset water tank temperature, it is first determined based on the user monitoring results whether there is a user who is sleeping, and the air conditioner indoor unit corresponding to the room where the sleeping user is located is used as the indoor unit to be adjusted.

[0075] Step S202, controlling the air conditioner to perform defrosting at night according to the indoor unit to be adjusted.

[0076] It should be understood that the electronic expansion valve of the indoor unit in the room corresponding to the indoor unit to be adjusted is determined to perform defrosting at night, specifically, it is divided into the situation where the user is sleeping and the situation where the user is not sleeping.

[0077] In a feasible implementation, in order to avoid disturbing the user when he is sleeping, step S202 includes: determining the electronic expansion valve of the room unit corresponding to the indoor unit to be adjusted; and closing the electronic expansion valve of the room unit corresponding to the indoor unit to be adjusted, and controlling the air conditioner to defrost at night.

[0078] In the specific implementation, when it is recognized that there is a user sleeping in the room, the electronic expansion valve of the indoor unit in the corresponding room will be temporarily closed during the defrosting process to prevent the sudden increase in defrosting frequency from causing the refrigerant flow sound to become louder, thereby affecting the user's sleep. Therefore, the electronic expansion valve of the indoor unit in the room where the indoor unit is to be adjusted is closed, and then the air conditioner is controlled according to Figure 2 Defrost as shown.

[0079] In a feasible implementation, in order to complete defrosting when the user is not sleeping, step S202 includes: when the user sleep detection result is that the user is not sleeping, obtaining a preset defrost expansion valve opening; and adjusting the electronic expansion valve of each room unit to the preset defrost expansion valve opening, and controlling the air conditioner to perform defrosting at night.

[0080] It should be noted that when it is determined that there is no user sleeping in the room corresponding to the air conditioner indoor unit, all the indoor electronic expansion valves (such as Figure 4 EXV A, EXV B, EXV C) in the defrost valve are adjusted to the preset defrost expansion valve opening to achieve night defrosting.

[0081] In this embodiment, when the water tank temperature is lower than the preset water tank temperature, the indoor unit to be adjusted corresponding to the user's sleeping room is determined according to the user detection result; and the air conditioner is controlled to perform defrosting at night according to the indoor unit to be adjusted. In this way, different operations are performed based on different sleeping situations of the user to achieve defrosting, and the defrosting operation noise is improved through sleep scene recognition, thereby improving the user's sleeping experience.

[0082] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the air conditioner control method of the present application.

In this way, it is realized to analyze the user's sleep situation in combination with the water tank temperature, and through the cooling of the water tank, the outdoor unit is defrosted while the indoor unit is continuously heated. Through the recognition of the sleep scene, the defrosting operation noise is improved, and the user's sleep experience is improved.
