[0034] The core of this utility model is to provide an air conditioner and its management and control equipment. When the voltage detection device determines that the air conditioner power supply is cut off, the energy stored in the energy storage backup device is used to provide emergency power to the processing device and the refrigerant control valve of the air conditioner, and the refrigerant control valve is immediately controlled to shut off. That is, the processing device can ensure that the refrigerant control valve is in the closed state before the power is completely cut off, thereby preventing a large amount of refrigerant leakage and improving the safety of air conditioner use.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] Please refer to Figure 1 , Figure 1 This utility model provides a structural schematic diagram of an air conditioner management and control device, which includes an air conditioner power supply 100, an energy storage backup power device 200, a voltage detection device 300, and a processing device 400.

[0037] The output terminal of the air conditioner power supply 100 is connected to the energy storage backup power device 200, the processing device 400 and the refrigerant control valve of the air conditioner respectively. The energy storage backup power device 200 is connected to the processing device 400 and the refrigerant control valve. The voltage detection device 300 is connected to the processing device 400 and the air conditioner power supply 100 respectively. The processing device 400 is connected to the refrigerant control valve. The refrigerant control valve is used to control the opening and closing of the refrigerant flow path. The refrigerant flow path is the flow path of refrigerant from the outdoor unit of the air conditioner to the indoor unit.

[0038] Voltage detection device 300 is used to detect the real-time voltage value at the output terminal of air conditioner power supply 100;

[0039] The processing device 400 is used to control the refrigerant control valve to shut off when it is determined by the real-time voltage value that the air conditioner power supply 100 will be cut off.

[0040] An energy storage backup power device is used to supply power to the processing device 200 and the refrigerant control valve using stored electrical energy under the control of the processing device 200.

[0041] Specifically, considering the technical problems mentioned above, and taking into account that the voltage of the air conditioner power supply 100 will drop rapidly when the air conditioner is powered off or in standby mode, and that refrigerant leakage will still occur even when the air conditioner is powered off, and that the air conditioner cannot prevent a large amount of refrigerant leakage by "closing the refrigerant control valve" when it is not working, that is, once refrigerant leakage occurs when the air conditioner is not working and the refrigerant control valve is in the open state, the refrigerant can flow from the outdoor unit to the indoor unit and cause a large amount of leakage, thereby causing serious safety hazards. Therefore, in this embodiment of the utility model, in the scenario where the air conditioner power supply 100 drops rapidly due to power outage or standby mode, the temporary power supply of the energy storage backup power device 200 is used to quickly control the refrigerant control valve to close, thereby preventing a large amount of refrigerant leakage caused by the inability to close the refrigerant control valve in time when the air conditioner is not working and a refrigerant leakage occurs.

[0042] Specifically, based on the above considerations, this utility model embodiment includes an energy storage backup power device 200. During normal operation, the air conditioner power supply 100 can charge the energy storage backup power device 200 to achieve energy storage. On the other hand, a voltage detection device 300 is provided for the processing device 400, allowing the processing device 400 to determine whether the air conditioner power supply 100 will be disconnected. In the event of a power outage, the processing device 400 can control the energy storage backup power device 200 to use the stored electrical energy to supply power to the processing device 400 and the refrigerant control valve, and control the refrigerant control valve to close. That is, the refrigerant control valve can be quickly closed before the electrical energy stored in the energy storage backup power device 200 is exhausted, thereby ensuring that even if refrigerant leakage occurs when the air conditioner is not working for a long time, the refrigerant located in the outdoor unit of the air conditioner will not flow to the indoor unit and cause an increase in leakage.

[0043] The specific process by which the voltage detection device 300 determines that the air conditioner will be powered off can be varied. For example, the air conditioner will be powered off when the output voltage of the air conditioner power supply 100 is lower than a preset threshold. The preset threshold can be set independently, for example, it can be 7V, etc. This embodiment of the present invention does not limit the specific process.

[0044] Specifically, for a better explanation of the embodiments of this utility model, please refer to... Figure 2 , Figure 2This is a schematic diagram of the structure of another air conditioner management and control device provided by this utility model. Reference numeral 1 is a switching power supply; reference numeral 2 is a second unidirectional single-pass device D1 (diode); reference numeral 3 is a supercapacitor charging management chip; reference numeral 4 is a controllable switch; reference numeral 5 is a 12V_C voltage detection circuit; reference numeral 6 is a boost circuit; reference numeral 7 is the main chip of the outdoor unit control board; reference numeral 8 is a first unidirectional conducting device D2 (diode); reference numeral 9 is a DC-DC step-down circuit; reference numeral 10 is a refrigerant control valve including a high-pressure valve and a low-pressure valve; reference numeral 11 is a gas sensor; reference numeral 12 is the main chip of the indoor unit control board; reference numeral 13 is the indoor unit control board; reference numeral 14 is the outdoor unit control board; and reference numeral 15 is a supercapacitor (i.e., an energy storage module).

[0045] Specifically, the structure of the air conditioner power supply 100 can be varied. For example, it may include a switching power supply connected to the mains power, a second unidirectional conducting device, and a DC step-down circuit. The positive terminal of the second unidirectional conducting device is connected to the output terminal of the switching power supply, and the negative terminal of the second unidirectional conducting device is connected to the DC step-down circuit and the refrigerant control valve. The switching power supply can output 12V_C (12V-13V DC voltage), while the DC step-down circuit can reduce the output voltage of the switching power supply to the voltage required by the processing device 400 (e.g., 3.3V or 5V).

[0046] in, Figure 2 The DC-DC step-down circuit in the text is a DC step-down circuit, where DC stands for direct current, and the processing device 400 is... Figure 2 The main chip of the outdoor unit control board, and the refrigerant control valve may include Figure 2 The high-pressure valve and low-pressure valve, and the refrigerant control valve can be installed on the refrigerant pipes of the outdoor unit. The second one-way conduction device can be... Figure 2 D1 in the circuit that detects 12V_C voltage is the voltage detection device 300.

[0047] This invention provides a management and control device for an air conditioner. Considering that the air conditioner's power supply voltage drops rapidly during power outages or standby mode, and that refrigerant leakage can still occur even when the air conditioner is powered off, this invention utilizes the stored electrical energy from an energy storage backup device to provide emergency power to the processing device and the air conditioner's refrigerant control valve when the voltage detection device determines that the air conditioner's power supply is off. It also immediately controls the refrigerant control valve to shut off, meaning that the processing device can ensure that the refrigerant control valve is in a closed state before a complete power outage, thereby preventing a large amount of refrigerant leakage and improving the safety of air conditioner use.

[0048] Based on the above embodiments:

[0049] As an optional embodiment, the processing device 400 is the main chip of the outdoor unit control board of the air conditioner.

[0057] In addition, considering that the output voltage of the energy storage module may not meet the voltage requirements of the refrigerant control valve, a boost circuit is provided in this embodiment of the invention. Under the control of the processing state, the boost circuit can boost the output voltage of the energy storage module to the required voltage of the refrigerant control valve (e.g., 12V), so that the refrigerant control valve can work more reliably (controlled to be shut off by the processing device 400), and can also be controlled to generate the voltage required by the processing device 400 itself.

[0058] The energy storage module can be of various types, such as a supercapacitor, and this embodiment of the present invention does not limit the specific type.

[0059] Specifically, the boost circuit can be of various types, such as a DC-DC converter, etc., and this embodiment of the present invention is not limited to these types.

The charging management chip is used to manage the charging of the energy storage module by controlling the on and off of the controllable switch under the control of the processing device 400.

[0065] The charging management chip can manage the energy storage module's charging in various ways, such as power management and charging speed management, which are not limited to the specific content of this embodiment.

[0066] As an optional embodiment, the controllable switch includes a first metal-oxide-semiconductor field-effect transistor and a second metal-oxide-semiconductor field-effect transistor;

[0067] The gates of both the first and second metal-oxide-semiconductor field-effect transistors are connected to the charging management chip.

The drains of both the first and second metal-oxide-semiconductor field-effect transistors are connected to the energy storage module. The source of the second metal-oxide-semiconductor field-effect transistor is grounded.

[0068] Specifically, considering that the charging speed and power management of the energy storage module can be stably achieved through two common-drain MOSFETs, the controllable switch in this embodiment of the present invention may include two MOSFETs: a first metal-oxide-semiconductor field-effect transistor and a second metal-oxide-semiconductor field-effect transistor.

[0073] Specifically, considering that the first one-way conduction device can prevent the current backflow from damaging the boost circuit, a first one-way conduction device is provided between the boost circuit and the refrigerant control valve in this embodiment of the invention.

[0074] As an optional embodiment, the air conditioning management and control device further includes an auxiliary processor connected to the processing unit 400;

[0075] The auxiliary processor is used to send indoor unit control board faults to the processing unit 400 so that the processing unit 400 can control the refrigerant control valve to shut off in the event of an indoor unit control board fault and / or an outdoor unit control board fault.

[0076] Specifically, considering that in the event of a fault in the indoor unit control board, the indoor unit control board may be unable to successfully report the refrigerant leak to the main chip of the indoor unit control board, and that in the event of a fault in both the indoor and outdoor unit control boards, the outdoor unit control board may become completely inoperable as the fault worsens, in order to prevent the refrigerant control valve from being unable to shut off in the event of a refrigerant leak, the processing device 400 in this embodiment of the present invention can control the refrigerant control valve to shut off when the indoor unit control board and / or the outdoor unit control board fails.

[0077] The auxiliary processor can be of various types, such as the main chip of the indoor unit control board of the air conditioner, which is originally responsible for the control of the indoor unit control board and can identify the fault of the indoor unit control board.
