[0001] The present application relates to the technical field of air conditioning control, and in particular, to an air conditioning control method, device, air conditioner and computer-readable storage medium. Background Art

[0002] At present, a standby circuit is often provided in an air conditioner to maintain the standby state of the air conditioner when the air conditioner is turned off but not powered off, wherein a relay and a thermistor in the standby circuit are often connected in parallel.

[0003] In the prior art, after the air conditioner is turned off, the relay in the standby circuit will always remain in a closed state, so the thermistor will not be connected. In this case, the resistance in the standby circuit is small, which will cause the standby power consumption of the air conditioner to be large. Summary of the invention

[0004] The problem solved by the present application is how to reduce the standby power consumption of the air conditioner.

[0005] To solve the above problems, the present application provides an air conditioning control method, device, air conditioner and computer-readable storage medium.

[0008] If the air conditioner is in a standby state, the relay in the standby circuit is controlled to be disconnected to connect the thermistor.

[0009] In the air conditioning control method provided by the embodiment of the present application, the air conditioner can determine whether the air conditioner is in a standby state according to the fan parameters and the compressor parameters when receiving a shutdown command, thereby controlling the relay in the standby circuit to be disconnected in the standby state to connect the thermistor. Since the state of the air conditioner can be judged after shutdown, when the air conditioner is in the standby state, the standby circuit is controlled to connect the thermistor, so the resistance in the standby circuit will increase, thereby reducing the standby power consumption of the air conditioner.

[0010] In an optional embodiment, the fan parameter includes a fan operation flag, and the compressor parameter includes a compressor operation flag and a compressor preheating flag;

[0011] The step of judging whether the air conditioner is in a standby state according to the fan parameter and the compressor parameter comprises:

[0013] If the fan operation flag indicates that the fan is in operation, or the compressor operation flag indicates that the compressor is in operation, or the compressor preheating flag indicates that the compressor is in preheating, it is determined that the air conditioner is not in standby mode.

[0014] The air conditioning control method provided in the embodiment of the present application can judge the status of the fan and the compressor according to the fan operation flag, the compressor operation flag and the compressor preheating flag, so as to determine whether the air conditioner is in standby mode. Therefore, the judgment process of the standby mode of the air conditioner can be simplified and the processing efficiency can be improved.

[0015] In an optional implementation, if the air conditioner is in a standby state, controlling the relay in the standby circuit to be disconnected to connect the thermistor comprises:

[0017] When the duration of the fan being in the stopped state reaches a first preset duration and / or the duration of the compressor being in the stopped state reaches a second preset duration, the relay in the standby circuit is controlled to be disconnected to connect the thermistor.

[0018] The air conditioning control method provided in the embodiment of the present application can determine whether to control the relay in the standby circuit to be disconnected according to the length of time the fan and the compressor stop running after the air conditioner is in the standby state, thereby preventing circuit faults caused by frequent opening and closing of the relay when the air conditioner is frequently started and stopped.

[0019] In an optional embodiment, the method further comprises:

[0020] When the air conditioner is powered on or reset, the relay is controlled according to the power-on time of the air conditioner.

[0021] In an optional implementation manner, when the air conditioner is powered on or reset, controlling the relay according to the power-on time of the air conditioner includes:

[0022] When the air conditioner is powered on or reset, the relay is controlled to be disconnected so as to connect the thermistor;

[0023] When the power-on time of the air conditioner reaches a third preset time, the relay is controlled to close to disconnect the thermistor.

[0024] The air conditioning control method provided in the embodiment of the present application can first control the relay to disconnect when the air conditioner is powered on or reset, thereby connecting the thermistor to charge the electrolytic capacitor in the standby circuit, and then control the relay to close to disconnect the thermistor after the power-on time of the air conditioner reaches a third preset time, thereby ensuring that there will be no problem of large current when the air conditioner is officially running, thereby improving power utilization and avoiding damage to the standby circuit.

[0025] In a second aspect, the present application provides an air conditioning control device, which is applied to an air conditioner, wherein the air conditioner is provided with a standby circuit, wherein the standby circuit includes a relay and a thermistor connected in parallel with the relay, and the device includes:

Since the state of the air conditioner can be judged after shutdown, when the air conditioner is in the standby state, the standby circuit is controlled to connect the thermistor, so the resistance in the standby circuit will become larger, thereby reducing the standby power consumption of the air conditioner.

[0029] In an optional embodiment, the fan parameter includes a fan operation flag, and the compressor parameter includes a compressor operation flag and a compressor preheating flag;

[0040] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0041] With the strong call for energy conservation and emission reduction, air conditioners need to further reduce energy consumption and improve efficiency, and how to reduce the standby power consumption of air conditioners is also an important part of this.

[0042] At present, a standby circuit is often provided in an air conditioner to maintain the standby state of the air conditioner when the air conditioner is turned off but not powered off, wherein a relay and a thermistor in the standby circuit are often connected in parallel.

[0043] In one example, Figure 1 For a schematic diagram of the standby circuit, see Figure 1 The relay can be connected in parallel with a thermistor PTC (Positive Temperature Coefficient).

[0044] In the prior art, when the air conditioner is turned off but not powered off, the relay will remain closed. In this case, the thermistor will not be connected to the standby circuit, and the resistance in the standby circuit is relatively small. According to the power calculation formula P = U*U / R, when the voltage is constant, the smaller the resistance, the greater the power, so the standby power consumption of the air conditioner will also be greater.

[0045] Based on this, the embodiments of the present application provide an air conditioning control method, device, air conditioner and computer-readable storage medium to perform detailed analysis on the specific state of the air conditioner after it is shut down, and when it is determined that the air conditioner is in standby state, a thermistor is connected in the standby circuit to increase the resistance in the standby circuit, thereby reducing the standby power consumption of the air conditioner.

[0046] Specifically, Figure 2 This is a block diagram of an air conditioner provided in an embodiment of the present application. The air conditioner includes an indoor unit 10 and an outdoor unit 20, and the indoor unit 10 is connected to the outdoor unit 20.

[0047] Optionally, the air conditioner is further provided with a processor, which can be used to execute a computer program to implement the air conditioning control method provided in the embodiment of the present application.

[0048] Optionally, the processor may be disposed in the indoor unit 10 or in the outdoor unit 20, and this application does not impose any further restrictions on this.

[0049] In this embodiment, the air conditioner is further provided with a standby circuit, and the standby circuit includes a relay and a thermistor connected in parallel with the relay.

[0050] In a possible implementation, the thermistor may be a PTC resistor.

[0051] Next, the above Figure 2The air conditioner in the embodiment is the execution subject, and the air conditioning control method provided in the embodiment of the present application is exemplarily introduced in combination with the flow chart.

[0052] Specifically, Figure 3 A flow chart of the air conditioning control method provided in the embodiment of the present application is shown in FIG. Figure 3 , the method comprising:

[0053] Step S20, when a shutdown instruction is received, the fan parameters and the compressor parameters of the air conditioner are obtained, and whether the air conditioner is in a standby state is determined according to the fan parameters and the compressor parameters.

[0054] Optionally, the air conditioner can determine the current state of the fan according to the fan parameters, and determine the current state of the compressor according to the compressor parameters.

[0055] It can be understood that since the fan and compressor are the core components of the air conditioning operation process, their status can directly reflect the operating status of the air conditioner. Based on this, the status of the fan and the status of the compressor can be combined to determine whether the air conditioner is in standby mode.

[0056] Step S21, if the air conditioner is in the standby state, the relay in the standby circuit is controlled to be disconnected to connect the thermistor.

[0057] Optionally, since the relay and the thermistor are connected in parallel, after the relay in the air conditioner control standby circuit is disconnected, the thermistor can be connected to the standby circuit.

[0058] In the air conditioning control method provided by the embodiment of the present application, the air conditioner can determine whether the air conditioner is in a standby state according to the fan parameters and the compressor parameters when receiving a shutdown command, thereby controlling the relay in the standby circuit to be disconnected in the standby state to connect the thermistor. Since the state of the air conditioner can be judged after shutdown, when the air conditioner is in the standby state, the standby circuit is controlled to connect the thermistor, so the resistance in the standby circuit will increase, thereby reducing the standby power consumption of the air conditioner.

[0059] Next, a possible implementation method is provided for determining whether the air conditioner is in standby mode based on the fan parameters and the compressor parameters.

[0060] Specifically, in order to facilitate the determination of the fan status and the compressor status, and thus determine whether the air conditioner is in standby mode, the fan parameter may include a fan operation flag, and the compressor parameter may include a compressor operation flag and a compressor preheating flag.

[0061] In this embodiment, if the fan operation identifier indicates that the fan of the air conditioner is in a stopped state, the compressor operation identifier indicates that the compressor of the air conditioner is in a stopped state, and the compressor preheating identifier indicates that the compressor is not in a preheating state, then it is determined that the air conditioner is in standby mode.

[0062] Optionally, since in the shutdown state, if the external ambient temperature is very low, the compressor will be controlled to enter the preheating state, that is, the compressor will be powered on to heat the compressor through the heat generated by the coil winding, so as to avoid the freezing of the lubricating oil and affect the start-up of the compressor. Therefore, when judging whether the air conditioner is in standby state, in addition to judging whether the compressor is in running state, it is also necessary to judge whether the compressor is in preheating state.

[0063] Optionally, if a thermistor is connected while there is still a load running in the air conditioner, the thermistor will continue to generate heat, and its resistance will increase, resulting in a large voltage drop, reducing power utilization, and even the thermistor may burn out and damage the standby circuit. Therefore, it is necessary to ensure that the air conditioner is completely in standby mode when the fan stops running, the compressor stops running, and the compressor is not in a preheating state, so as to control the relay to disconnect and connect the thermistor to the standby circuit.

[0064] It can be understood that if the fan operation mark indicates that the fan is in operation, or the compressor operation mark indicates that the compressor is in operation, or the compressor preheating mark indicates that the compressor is in preheating, it is determined that the air conditioner is not in standby mode.

[0065] Optionally, considering that the air conditioner may have the problem of frequent start and stop, if the relay in the standby circuit is disconnected when the air conditioner just enters the standby state, it may cause the relay to open and close frequently, resulting in a malfunction. Based on this, the relay in the standby circuit can be controlled to be disconnected after determining a period of time after the air conditioner enters the standby state.

[0066] Specifically, if the air conditioner is in the standby state, it is determined whether the duration of the fan being in the stopped state reaches a first preset duration and / or whether the duration of the compressor being in the stopped state reaches a second preset duration.

[0067] In this embodiment, when the fan is in a stopped state for a first preset time and / or the compressor is in a stopped state for a second preset time, the air conditioner can control the relay in the standby circuit to disconnect to connect the thermistor.

[0068] In this embodiment, if the air conditioner is in standby mode, both the fan and the compressor stop running. At this time, whether to disconnect the relay can be determined only by the length of time the compressor stops running, or only by the length of time the fan stops running. It can also be determined whether to disconnect the relay by combining the length of time the fan stops running and the length of time the compressor stops running.

[0069] Optionally, the first preset duration and the second preset duration may be set by the user according to actual application conditions. The first preset duration and the second preset duration may be the same or different, and this application does not impose any further restrictions on this.

[0070] In one possible implementation, the first preset duration and the second preset duration may both be 4 minutes.

[0071] Optionally, if the user sends a power-on command to the air conditioner after a period of standby, the air conditioner may first close the relay and then operate according to the control command.

[0072] Optionally, after a period of standby, the user may power off the air conditioner and then power it back on, or reset the air conditioner. To ensure that the air conditioner can operate normally after being powered on or reset, it is necessary to control the relay according to the power-on time of the air conditioner when the air conditioner is powered on or reset.

[0073] Specifically, when the air conditioner is powered on or reset, the relay can be controlled to be disconnected to connect the thermistor. Thereafter, when the power-on time of the air conditioner reaches a third preset time, the relay is controlled to be closed to disconnect the thermistor.

[0074] In this embodiment, an electrolytic capacitor is also provided in the standby circuit, so when the air conditioner is powered on or reset, a thermistor needs to be connected first to charge the electrolytic capacitor.

[0075] Optionally, the third preset time length may be a charging time length of an electrolytic capacitor, which may be set according to actual application conditions. In a possible implementation, the third preset time length may be 2 seconds.

[0076] Optionally, if the thermistor is connected when the air conditioner is officially running, it will cause a large current, and the thermistor will continue to heat up, its resistance will increase, resulting in a large voltage drop, reducing power utilization, and even the thermistor may burn out, causing damage to the standby circuit. Therefore, in order to ensure that the air conditioner can operate safely and normally, it is necessary to disconnect the thermistor before the air conditioner is officially operated.

[0077] For an example, see Figure 1When the air conditioner is powered on or reset, the relay needs to be controlled to disconnect first to connect the thermistor PTC. The power supply can charge the electrolytic capacitor through the PTC. After the third preset time, the voltage of the electrolytic capacitor can rise to the preset value. At this time, the relay can be controlled to close to disconnect the PTC resistor.

[0078] The present application also provides an air conditioning control device, specifically, Figure 4 For a block diagram of the air conditioning control device provided in the embodiment of the present application, please refer to Figure 4 The air conditioning control device includes a judgment module 200 and a control module 210.

[0079] The judgment module 200 is used to obtain the fan parameters and compressor parameters of the air conditioner when receiving the shutdown command, and judge whether the air conditioner is in the standby state according to the fan parameters and the compressor parameters.

[0080] It can be understood that the determination module 200 can also be used to execute the above step S20.

[0081] The control module 210 is used to control the relay in the standby circuit to be disconnected to connect the thermistor if the air conditioner is in the standby state.

[0082] It can be understood that the control module 210 can also be used to execute the above step S21.

[0083] Optionally, the judgment module 200 is also used to determine that the air conditioner is in standby state if the fan operation identifier indicates that the fan of the air conditioner is in a stopped state, the compressor operation identifier indicates that the compressor of the air conditioner is in a stopped state, and the compressor preheating identifier indicates that the compressor is not in a preheating state; if the fan operation identifier indicates that the fan is in an operating state, or the compressor operation identifier indicates that the compressor is in an operating state, or the compressor preheating identifier indicates that the compressor is in a preheating state, then it is determined that the air conditioner is not in standby state.

[0084] Optionally, the control module 210 is also used to determine, if the air conditioner is in standby mode, whether the duration of the fan being in the stopped state reaches a first preset duration and / or whether the duration of the compressor being in the stopped state reaches a second preset duration; when the duration of the fan being in the stopped state reaches the first preset duration and / or the duration of the compressor being in the stopped state reaches the second preset duration, control the relay in the standby circuit to disconnect so as to connect the thermistor.

[0085] Optionally, the control module 210 is further configured to control the relay according to the power-on time of the air conditioner when the air conditioner is powered on or reset.

[0086] Optionally, the control module 210 is also used to control the relay to disconnect to connect the thermistor when the air conditioner is powered on or reset; when the power-on time of the air conditioner reaches a third preset time, control the relay to close to disconnect the thermistor.

[0087] The embodiment of the present application also provides a computer-readable storage medium on which a computer program is stored. When the computer program is executed by a processor, the air conditioning control method provided in the embodiment of the present application can be implemented.
