[0038] In this embodiment of the disclosure, smart home appliances refer to home appliances formed by introducing microprocessors, sensor technology and network communication technology into home appliances. They have the characteristics of intelligent control, intelligent sensing and intelligent application. The operation of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet and electronic chips. For example, smart home appliances can be connected to electronic devices to enable users to remotely control and manage smart home appliances.

[0039] In this embodiment of the disclosure, the terminal device refers to an electronic device with wireless connectivity. The terminal device can communicate with the aforementioned smart home appliances by connecting to the internet, or directly via Bluetooth, Wi-Fi, or other methods. In some embodiments, the terminal device may be, for example, a mobile device, a computer, or an in-vehicle device built into a hovercraft, or any combination thereof. Mobile devices may include, for example, mobile phones, smart home devices, wearable devices, smart mobile devices, virtual reality devices, or any combination thereof. Wearable devices may include, for example, smartwatches, smart bracelets, pedometers, etc.

[0040] In this embodiment, combined with Figures 1-1 to 1-3 As shown, the cabinet air conditioner comprises an indoor heat exchanger, an outdoor condenser 5, a compressor 4, a four-way reversing valve 6, multiple throttling devices, a heat storage module 8, and an air supply module. Specifically, the dual air supply system of the cabinet air conditioner consists of two motors, two fans, and two sets of air guides. The first indoor air supply module 71 and the second indoor air supply module 72 are independently controlled. The indoor heat exchanger consists of a first indoor evaporator 31 and a second indoor evaporator 32 connected in parallel. A second throttling device 112 and a third throttling device 113 are respectively installed before the inlet of the first indoor evaporator 31 and the second indoor evaporator 32. The cabinet air conditioner can achieve differentiated control of cooling and heating in the same space area and at the same time by independently controlling the inlet flow of the first indoor evaporator 31 and the second indoor evaporator 32.

[0041] Figure 1-1 This is a schematic diagram of a cabinet air conditioner's heating and defrosting cycle provided in an embodiment of this disclosure; combined with Figure 1-1As shown, optionally, when the cabinet air conditioner is running in defrost mode, the cabinet air conditioner will close the second throttling device 112 or the third throttling device 113 while running in heating mode, and at the same time open the first throttling device 111 on the outdoor side 1, so that the high-temperature refrigerant compressed from the compressor 4 flows through only one indoor evaporator, reducing the consumption of high-temperature refrigerant on the indoor side 2 and effectively increasing the residual heat of the outdoor condenser 5 during defrosting; at the same time, the fourth throttling device 114 located on the exhaust pipe of the compressor 4 and the fifth throttling device 115 located at the outlet will be opened, so that the bypass refrigerant flows through the heat storage module 8 and then merges into the main exhaust pipe to participate in the circulation. At this time, the heat storage module 8 can perform heat storage operation, and the refrigerant participates in defrosting and flows out from the outdoor heat exchanger (outdoor condenser) 5, and controls the shut-off valve 9 to close. At the same time, the sixth throttling device 116 and the seventh throttling device 117 will be activated so that the refrigerant flows into the heat storage module 8 to absorb the heat of the heat storage module 8 and evaporate back to the return port of the compressor 4, thereby forming a heating defrosting circuit.

[0042] Figure 1-2 This is a schematic diagram of the cooling cycle of a cabinet air conditioner provided in an embodiment of this disclosure; combined with Figure 1-2 As shown, when the cabinet air conditioner is in cooling mode, the refrigerant flows through the compressor 4 and is compressed into a high-temperature and high-pressure gas. The high-temperature and high-pressure gaseous refrigerant transfers heat to the outside through the outdoor condenser 5 and becomes a low-temperature and low-pressure liquid refrigerant. The liquid refrigerant enters the indoor side 2 after being throttled and depressurized by the throttling device. The cabinet air conditioner automatically controls the opening of the second throttling device 112 and the third throttling device 113 according to the user's needs, thereby realizing differentiated heat exchange requirements.

[0043] Figure 1-3 This is a schematic diagram of the heating cycle of a cabinet air conditioner provided in an embodiment of this disclosure; combined with Figure 1-3 As shown, when the cabinet air conditioner is operating in heating mode, the low-temperature, low-pressure gaseous refrigerant is compressed into a high-temperature, high-pressure gas by the compressor 4. The high-temperature, high-pressure gaseous refrigerant enters the first indoor evaporator 31 and / or the second indoor evaporator 32 on the indoor side 2. The cabinet air conditioner can automatically control the opening of the second throttling device 112 and the third throttling device 113 according to user needs, thereby adjusting the refrigerant flow to meet differentiated heat exchange requirements. Specifically, when the cabinet air conditioner is operating in heating mode, it closes the fourth throttling device 114, the fifth throttling device 115, the sixth throttling device 116, and the seventh throttling device 117 on the outdoor side, and opens the first throttling device 111, the second throttling device 112, and the third throttling device 113, and opens the shut-off valve 9.

[0044] Figure 2 This is a schematic diagram of a method for controlling a cabinet air conditioner provided in an embodiment of this disclosure; combined with Figure 2 As shown, optionally, embodiments of this disclosure provide a method for controlling a cabinet air conditioner, comprising:

[0045] S21, the cabinet air conditioner obtains the outdoor ambient temperature where the cabinet air conditioner is located, the heating capacity of the cabinet air conditioner, and the operating time of the cabinet air conditioner compressor.

[0046] S22, when the ambient temperature of the outdoor unit where the air conditioner is located, the heating capacity of the air conditioner, and the running time of the air conditioner compressor all meet the defrosting start conditions, the air conditioner determines the target defrosting strategy.

[0047] S23, the cabinet air conditioner controls the cabinet air conditioner to execute the target defrosting strategy in defrosting mode.

[0048] In this solution, the floor-standing air conditioner can collect the ambient temperature of its location outdoors through its associated outdoor temperature sensor. The floor-standing air conditioner obtains its heating capacity by: acquiring the real-time coil temperature and the ambient temperature of the room where it is located; and using the difference between the real-time coil temperature and the ambient temperature as its heating capacity. The floor-standing air conditioner can also calculate the compressor's operating time by combining the compressor's start-up time and the current time. In this way, accurate acquisition of the outdoor ambient temperature, heating capacity, and compressor operating time can be achieved.

[0049] Furthermore, the floor-standing air conditioner can determine whether the defrost start conditions are met in the following way: The floor-standing air conditioner uses the ratio of its heating capacity to a reference heating value as a first ratio. If the outdoor ambient temperature is lower than the target temperature threshold, the first ratio is not higher than the first threshold, and the compressor's operating time exceeds the target duration threshold, then the floor-standing air conditioner determines that the outdoor ambient temperature, heating capacity, and compressor operating time all meet the defrost start conditions. In this way, when the outdoor ambient temperature, heating capacity, and compressor operating time all meet the defrost start conditions, the floor-standing air conditioner can determine its target defrost strategy. Here, the target defrost strategy includes a light frost handling strategy or a heavy frost handling strategy. After determining the target defrost strategy, the floor-standing air conditioner can control itself to execute the target defrost strategy in defrost mode.

[0050] The method for controlling a cabinet air conditioner provided in this disclosure acquires the outdoor ambient temperature, the heating capacity of the air conditioner, and the operating time of the compressor. When these conditions are met, a target defrosting strategy is determined, and the air conditioner is controlled to execute this strategy in defrosting mode. This approach effectively improves defrosting efficiency and mitigates the significant temperature drop during defrosting, enhancing both the user experience and reliability of the air conditioner.

[0051] Figure 3 This is a schematic diagram of a method for determining defrosting start conditions provided in an embodiment of this disclosure; combined with Figure 3 As shown, optionally, the outdoor ambient temperature where the cabinet air conditioner is located, the heating capacity of the cabinet air conditioner, and the operating time of the cabinet air conditioner compressor are all determined to meet the defrost start conditions by means of the following methods:

[0052] S31, the ratio of the heating capacity of the cabinet air conditioner to the reference value of the heating capacity is used as the first ratio.

[0053] S32, when the ambient temperature outside the cabinet air conditioner is lower than the target temperature threshold, the first ratio is not higher than the first threshold, and the running time of the cabinet air conditioner compressor is greater than the target duration threshold, the cabinet air conditioner determines that the ambient temperature outside the cabinet air conditioner, the heating capacity of the cabinet air conditioner, and the running time of the cabinet air conditioner compressor all meet the defrost start conditions.

[0054] In this solution, after the floor-standing air conditioner calculates a heat reference value, the ratio of its heating capacity to the heat reference value can be calculated and used as the first ratio. If the outdoor ambient temperature is below the target temperature threshold, the first ratio is not higher than the first threshold, and the compressor's operating time exceeds the target duration threshold, then the floor-standing air conditioner determines that the outdoor ambient temperature, heating capacity, and compressor operating time all meet the defrost start conditions. The target temperature threshold is the initial ambient temperature at which frost forms at the location of the air conditioner; the first threshold is 0.8; and the target duration threshold is the user-preset duration after startup before defrosting. This method allows for accurate determination of whether the defrost start conditions are met.

[0055] Figure 4 This is a schematic diagram of a method for determining a target defrosting strategy provided in an embodiment of this disclosure; combined with Figure 4 As shown, optionally, in step S22, the cabinet air conditioner determines the target defrosting strategy, including:

[0056] S41, the cabinet air conditioner calculates the heat reference value based on the standard indoor coil temperature and the standard indoor ambient temperature.

[0057] S42, the ratio of the heating capacity of the cabinet air conditioner to the reference value of the heating capacity is used as the first ratio.

[0058] S43, the cabinet air conditioner determines the target defrosting strategy based on the first ratio.

[0059] In this solution, the floor-standing air conditioner can obtain the standard indoor coil temperature and the standard indoor ambient temperature. Here, the standard indoor coil temperature is the average of the coil temperature over five consecutive cycles in a non-frosting state. As an example, each cycle is 1 minute. The standard indoor ambient temperature is the average of the indoor ambient temperature over five consecutive cycles in a non-frosting state. Thus, after obtaining the standard indoor coil temperature and the standard indoor ambient temperature, the difference between the two can be used as a heat reference value. In this way, the heat reference value can be accurately calculated.

[0060] Furthermore, the floor-standing air conditioner can use the calculated quotient of its heating capacity and a reference heating value as a first ratio. Based on this first ratio, the target defrosting strategy for the floor-standing air conditioner is determined. Specifically, the target defrosting strategy for the floor-standing air conditioner is determined according to the first ratio, including: if the first ratio is not higher than a first threshold but higher than a second threshold, the target defrosting strategy is a light frost treatment strategy; if the first ratio is lower than the second threshold, the target defrosting strategy is a heavy frost treatment strategy. In this way, the target defrosting strategy can be accurately determined by combining the calculated first ratio.

[0061] Optionally, S43, the cabinet air conditioner determines the target defrosting strategy based on the first ratio, including:

[0062] If the first ratio is not higher than the first threshold and is higher than the second threshold, the cabinet air conditioner determines that the target defrosting strategy for the cabinet air conditioner is the micro-frost treatment strategy.

[0063] If the first ratio is lower than the second threshold, the cabinet air conditioner determines that the target defrosting strategy is the thick frost treatment strategy.

[0064] In this scheme, the first threshold is 0.8, and the second threshold is 0.6. This allows the target defrosting strategy for the cabinet air conditioner to be determined as a light frost treatment strategy when the first ratio is no higher than 0.8 but higher than 0.6; and the target defrosting strategy for the cabinet air conditioner to be determined as a heavy frost treatment strategy when the first ratio is lower than 0.6. This method, combined with the calculated first ratio, enables precise determination of the target defrosting strategy.

[0065] Figure 5 This is a schematic diagram of a micro-frost treatment strategy according to an embodiment of this disclosure; combined with Figure 5 As shown, optionally, the microfrost treatment strategy includes:

[0066] S51, the cabinet air conditioner determines the target air outlet that is farthest from the user among multiple air outlets.

[0067] S52, Cabinet Air Conditioner Control: The cabinet air conditioner controls the air supply module and throttling device inside the target air outlet to shut off.

[0068] S53, when the throttling device on the outdoor side of the cabinet air conditioner is activated and the conditions for micro-frost treatment are met, the cabinet air conditioner restarts the air supply module inside the target air outlet at a low fan speed.

[0069] In this solution, the cabinet air conditioner can acquire the user's location information through radar sensors and determine the target air outlet farthest from the user among multiple air outlets. Furthermore, the cabinet air conditioner controls the air supply module and throttling device inside the target air outlet to shut off. This facilitates the indoor side entering single-evaporator heat exchange mode.

[0070] Furthermore, if the outdoor throttling device of the floor-standing air conditioner is activated and the conditions for micro-frost treatment are met, the air conditioner can restart the air supply module inside the target air outlet at a low fan speed. For example, if the floor-standing air conditioner determines that less heat is needed for defrosting, it confirms that the micro-frost treatment conditions are met. This solution ensures rapid defrosting while simultaneously activating the air conditioner's "following the user" mode, improving user comfort.

[0071] Alternatively, thick cream treatment strategies include:

[0072] The cabinet air conditioner control system shuts down the throttling device inside any air outlet while simultaneously shutting down the air supply module inside each air outlet.

[0073] In this solution, the cabinet air conditioner can control the throttling device inside any air outlet to shut down the air supply module inside each air outlet simultaneously. This allows the heat exchanger to avoid absorbing indoor heat and instead transfer higher heat to the outside, thus enabling rapid defrosting of the outdoor unit of the cabinet air conditioner.

[0074] Figure 6 This is a schematic diagram of another method for controlling a cabinet air conditioner provided in this disclosure embodiment; combined with Figure 6 As shown, optionally, after the control unit air conditioner executes the target defrosting strategy in defrosting mode, it further includes:

[0075] S61, the cabinet air conditioner obtains the execution time of the air conditioner's target defrosting strategy and the ratio of the current heating capacity of the cabinet air conditioner to the heating reference value;

[0076] S62, if the execution time exceeds the preset time threshold and / or the ratio of the current heating capacity of the cabinet air conditioner to the heat reference value is greater than the first threshold, the cabinet air conditioner controls the cabinet air conditioner to stop running the defrost mode and stops executing the target defrost strategy.

[0077] In this solution, the floor-standing air conditioner can obtain its current heating capacity and calculate the quotient between the current heating capacity and a reference heating value. Additionally, the floor-standing air conditioner can obtain the execution duration of the target defrosting strategy through its associated timing module. This method enables accurate data acquisition.

[0078] Furthermore, if the execution time exceeds a preset time threshold and / or the ratio of the current heating capacity of the floor-standing air conditioner to the heat reference value is greater than a first threshold, the floor-standing air conditioner will stop operating the defrost mode and simultaneously cease executing the target defrost strategy. The preset time threshold is a defrost time limit set by the user, and the first threshold is 0.8. This method accurately determines the timing of stopping the target defrost strategy, providing a precise data foundation for the energy-saving control of the floor-standing air conditioner.

[0079] Figure 7 This is a schematic diagram of a device for controlling a cabinet air conditioner provided in an embodiment of this disclosure; combined with Figure 7 As shown, this embodiment of the present disclosure provides a device 200 for controlling a cabinet air conditioner, including an acquisition module 71, a determination module 72, and a control module 73. The acquisition module 71 is configured to acquire the outdoor ambient temperature where the cabinet air conditioner is located, the heating capacity of the cabinet air conditioner, and the operating time of the cabinet air conditioner compressor; the determination module 72 is configured to determine a target defrosting strategy for the cabinet air conditioner when the outdoor ambient temperature, the heating capacity of the cabinet air conditioner, and the operating time of the cabinet air conditioner compressor all meet the defrosting start conditions; the control module 73 is configured to execute the target defrosting strategy when the cabinet air conditioner is in defrosting mode.

[0080] The device 200 for controlling a cabinet air conditioner provided in this embodiment acquires the outdoor ambient temperature, the heating capacity of the air conditioner, and the operating time of the compressor. When these conditions are met for defrosting to start, a target defrosting strategy is determined, and the air conditioner is controlled to execute this strategy in defrosting mode. This solution effectively improves defrosting efficiency and reduces the significant drop in indoor temperature during defrosting, enhancing both the user experience and reliability of the air conditioner.
