Air conditioner control method and device, air conditioner and computer readable storage medium

Abstract

Embodiments of the present application provide an air conditioner control method and device, an air conditioner and a computer readable storage medium, and relate to the technical field of air conditioner control. In the case of receiving a shutdown instruction, fan parameters and compressor parameters of the air conditioner are acquired, and it is determined whether the air conditioner is in a standby state according to the fan parameters and the compressor parameters. If the air conditioner is in the standby state, a relay in a standby loop is controlled to be disconnected to access a thermistor. Since the state of the air conditioner can be determined after shutdown, the standby loop accesses the thermistor when the air conditioner is in the standby state, so the resistance in the standby loop becomes larger, thereby reducing the standby power consumption of the air conditioner.

Description

Technical Field

[0001] This application relates to the field of air conditioning control technology, and more specifically, to an air conditioning control method, device, air conditioner, and computer-readable storage medium. Background Technology

[0002] Currently, air conditioners are often equipped with a standby circuit to maintain the standby state of the air conditioner when it is turned off but not powered off. In this standby circuit, the relay and thermistor are often connected in parallel.

[0003] In the prior art, after the air conditioner is turned off, the relay in the standby circuit remains closed, so the thermistor is not connected. Under these circumstances, the resistance in the standby circuit is small, which leads to a large standby power consumption of the air conditioner. Summary of the Invention

[0004] The problem addressed in this application is how to reduce the standby power consumption of air conditioners.

[0005] To address the aforementioned problems, this application provides an air conditioning control method, apparatus, air conditioner, and computer-readable storage medium.

[0006] In a first aspect, this application provides an air conditioning control method applied to an air conditioner, wherein the air conditioner is provided with a standby circuit, the standby circuit including a relay and a thermistor connected in parallel with the relay, the method comprising:

[0007] Upon receiving a shutdown command, the fan parameters and compressor parameters of the air conditioner are obtained, and the air conditioner is determined to be in standby mode based on the fan parameters and compressor parameters.

[0008] If the air conditioner is in standby mode, the relay in the standby circuit is disconnected to connect the thermistor.

[0009] The air conditioning control method provided in this application allows the air conditioner to determine whether it is in standby mode based on fan and compressor parameters upon receiving a shutdown command. In standby mode, the method controls the relay in the standby circuit to disconnect, thereby connecting a thermistor. Since the air conditioner's status can be determined after shutdown, and the thermistor is connected to the standby circuit when the air conditioner is in standby mode, the resistance in the standby circuit increases, thus reducing the standby power consumption of the air conditioner.

[0010] In an optional implementation, the fan parameters include a fan operation identifier, and the compressor parameters include a compressor operation identifier and a compressor preheating identifier;

[0011] The step of determining whether the air conditioner is in standby mode based on the fan parameters and the compressor parameters includes:

[0012] If the fan operation indicator indicates that the air conditioner's fan is in a stopped state, the compressor operation indicator indicates that the air conditioner's compressor is in a stopped state, and the compressor preheating indicator indicates that the compressor is not in a preheating state, then the air conditioner is determined to be in a standby state.

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

[0014] The air conditioning control method provided in this application can determine the status of the fan and compressor based on the fan operation indicator, compressor operation indicator and compressor preheating indicator, thereby determining whether the air conditioner is in standby mode. Therefore, it can simplify the process of determining the standby mode of the air conditioner and improve processing efficiency.

[0015] In an optional implementation, the step of controlling the relay in the standby circuit to disconnect and connect the thermistor if the air conditioner is in standby mode includes:

[0016] If the air conditioner is in standby mode, then determine whether the duration of the fan being in a stopped state has reached a first preset duration and / or whether the duration of the compressor being in a stopped state has reached a second preset duration.

[0017] If the duration of the fan being stopped reaches a first preset duration and / or the duration of the compressor being stopped reaches a second preset duration, the relay in the standby circuit is controlled to disconnect, so as to connect the thermistor.

[0018] The air conditioning control method provided in this application can determine whether to disconnect the relay in the standby circuit based on the duration of the fan and compressor stopping operation after the air conditioner is in standby mode. Therefore, it can prevent circuit failures caused by frequent opening and closing of the relay when the air conditioner is frequently started and stopped.

[0019] In an optional implementation, the method further includes:

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

[0021] In an optional implementation, controlling the relay based on the power-on duration of the air conditioner when it is powered on or reset includes:

[0022] When the air conditioner is powered on or reset, the relay is controlled to disconnect so that the thermistor can be connected;

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

[0024] The air conditioning control method provided in this application embodiment can, when the air conditioner is powered on or reset, first control the relay to disconnect, thereby connecting the thermistor to charge the electrolytic capacitor in the standby circuit. Then, after the power-on time of the air conditioner reaches a third preset time, control the relay to close to disconnect the thermistor. This can ensure that there will be no problem of excessive current when the air conditioner is in normal operation, improve power utilization, and avoid damage to the standby circuit.

[0025] Secondly, this application provides an air conditioning control device for use in an air conditioner, wherein the air conditioner is provided with a standby circuit, the standby circuit including a relay and a thermistor connected in parallel with the relay, and the device includes:

[0026] The judgment module is used to obtain the fan parameters and compressor parameters of the air conditioner when a power-off command is received, and to determine whether the air conditioner is in standby mode based on the fan parameters and compressor parameters.

[0027] The control module is used to control the relay in the standby circuit to disconnect so as to connect the thermistor if the air conditioner is in standby mode.

[0028] The air conditioning control device provided in this application embodiment obtains the fan parameters and compressor parameters of the air conditioner upon receiving a shutdown command through a judgment module. Based on these parameters, it determines whether the air conditioner is in standby mode. Furthermore, when the air conditioner is in standby mode, the control module controls the relay in the standby circuit to disconnect, thereby connecting the thermistor. Because the air conditioner's status can be determined after shutdown, and the thermistor is connected to the standby circuit when the air conditioner is in standby mode, the resistance in the standby circuit increases, thus reducing the standby power consumption of the air conditioner.

[0029] In an optional implementation, the fan parameters include a fan operation identifier, and the compressor parameters include a compressor operation identifier and a compressor preheating identifier;

[0030] The judgment module is further configured to determine that the air conditioner is in standby mode if the fan operation indicator indicates that the air conditioner's fan is in a stopped state, the compressor operation indicator indicates that the air conditioner's compressor is in a stopped state, and the compressor preheating indicator indicates that the compressor is not in a preheating state; and to determine that the air conditioner is not in standby mode if the fan operation indicator indicates that the fan is in operation, or the compressor operation indicator indicates that the compressor is in operation, or the compressor preheating indicator indicates that the compressor is in a preheating state.

[0031] In an optional implementation, the control module is further configured to, if the air conditioner is in standby mode, determine whether the duration of the fan being in a stopped state has reached a first preset duration, and whether the duration of the compressor being in a stopped state has reached a second preset duration; and if the duration of the fan being in a stopped state has reached the first preset duration, and the duration of the compressor being in a stopped state has reached the second preset duration, control the relay in the standby circuit to disconnect so as to connect the thermistor.

[0032] Thirdly, this application provides an air conditioner including a processor, the processor being configured to execute a computer program to implement the method described in any of the foregoing embodiments.

[0033] Fourthly, this application provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the method described in any of the foregoing embodiments. Attached Figure Description

[0040] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, specific embodiments of this application will be 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 reducing the standby power consumption of air conditioners is an important part of this.

[0042] Currently, air conditioners are often equipped with a standby circuit to maintain the standby state of the air conditioner when it is turned off but not powered off. In this standby circuit, the relay and thermistor are often connected in parallel.

[0043] In one example Figure 1 For a schematic diagram of the standby circuit, please refer to [link / reference]. Figure 1 This relay can be connected in parallel with a thermistor PTC (Positive Temperature Coefficient).

[0044] In existing technology, when the air conditioner is turned off but not powered down, the relay remains closed. In this case, the thermistor is not connected to the standby circuit, and the resistance in the standby circuit is relatively low. According to the power calculation formula P = U * U / R, with a constant voltage, the lower the resistance, the higher the power, and therefore the higher the standby power consumption of the air conditioner.

[0045] Based on this, embodiments of this application provide an air conditioning control method, device, air conditioner, and computer-readable storage medium to perform detailed analysis of the specific state of the air conditioner after it is turned off. When it is determined that the air conditioner is in standby mode, a thermistor is connected in the standby circuit to increase the resistance in the standby circuit and thereby reduce 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 this 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 computer programs to implement the air conditioning control method provided in the embodiments of this application.

[0048] Optionally, the processor can be installed in the indoor unit 10 or the outdoor unit 20; this application does not impose any further limitations on this.

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

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

[0051] The following is based on the above. Figure 2The air conditioner is the main actuator in this application. The air conditioning control method provided in this application embodiment is described by way of example in conjunction with the flowchart.

[0052] Specifically, Figure 3 Please refer to the flowchart of an air conditioning control method provided in this application embodiment. Figure 3 The method includes:

[0053] Step S20: Upon receiving a shutdown command, obtain the fan parameters and compressor parameters of the air conditioner, and determine whether the air conditioner is in standby mode based on the fan parameters and compressor parameters.

[0054] Optionally, the air conditioner can determine the current status of the fan based on the fan parameters, and determine the current status of the compressor based on the compressor parameters.

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

[0056] Step S21: If the air conditioner is in standby mode, the relay in the standby circuit is disconnected to connect the thermistor.

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

[0058] The air conditioning control method provided in this application allows the air conditioner to determine whether it is in standby mode based on fan and compressor parameters upon receiving a shutdown command. In standby mode, the method controls the relay in the standby circuit to disconnect, thereby connecting a thermistor. Since the air conditioner's status can be determined after shutdown, and the thermistor is connected to the standby circuit when the air conditioner is in standby mode, the resistance in the standby circuit increases, thus reducing the standby power consumption of the air conditioner.

[0059] The following section provides a possible method for determining whether an air conditioner is in standby mode based on fan and compressor parameters.

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

[0061] In this embodiment, if the fan operation indicator indicates that the air conditioner's fan is in a stopped state, the compressor operation indicator indicates that the air conditioner's compressor is in a stopped state, and the compressor preheating indicator indicates that the compressor is not in a preheating state, then the air conditioner is determined to be in a standby state.

[0062] Optionally, since the compressor will enter a preheating state when the unit is off if the ambient temperature is very low, the compressor will be powered on to heat the compressor through the coil windings, thus preventing the lubricating oil from freezing and affecting the compressor's start-up. Therefore, when determining whether the air conditioner is in standby mode, in addition to determining whether the compressor is running, it is also necessary to determine whether the compressor is in preheating mode.

[0063] Optionally, if a thermistor is connected while the air conditioner is still under load, the thermistor will continue to heat up, its resistance will increase, resulting in a large voltage drop, reducing power utilization, and may even cause the thermistor to burn out or damage the standby circuit. Therefore, it is necessary to ensure that the air conditioner is fully in standby mode only after the fan and compressor have stopped running and the compressor is not in preheating mode, so as to control the relay to disconnect and connect the thermistor in the standby circuit.

[0064] Understandably, if the fan operation indicator indicates that the fan is running, or the compressor operation indicator indicates that the compressor is running, or the compressor preheating indicator indicates that the compressor is preheating, then the air conditioner is not in standby mode.

[0065] Alternatively, considering that the air conditioner may frequently start and stop, if the relay in the standby circuit is disconnected as soon as the air conditioner enters standby mode, it may cause the relay to frequently open and close, leading to a malfunction. Therefore, the relay in the standby circuit can be disconnected after a certain period of time has passed since the air conditioner entered standby mode.

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

[0067] In this embodiment, when the fan has been in a stopped state for a first preset duration and / or the compressor has been in a stopped state for a second preset duration, the air conditioner can control the relay in the standby circuit to disconnect so as 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, it can be determined whether to disconnect the relay based solely on the duration the compressor stops running, or solely on the duration the fan stops running, or by combining both the duration the fan stops running and the duration the compressor stops running.

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

[0070] In one possible implementation, both the first preset duration and the second preset duration can 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 can first close the relay and then operate according to the control command.

[0072] Optionally, after a period of standby, the user may power off and power on the air conditioner, or reset the air conditioner. In order to ensure that the air conditioner can operate normally after being powered on or reset, the relay needs to be controlled according to the power-on time of the air conditioner when it is powered on or reset.

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

[0074] In this embodiment, an electrolytic capacitor is also provided in the standby circuit. Therefore, 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 duration can be the charging duration of the electrolytic capacitor, which can be set according to the actual application. In one possible implementation, the third preset duration can be 2 seconds.

[0076] Alternatively, if the thermistor is connected when the air conditioner is in operation, it will result in a large current and the thermistor will continue to heat up, causing its resistance to rise and resulting in a large voltage drop, reducing power utilization, and may even cause the thermistor to burn out, thus damaging the standby circuit. Therefore, in order to ensure that the air conditioner can operate safely and normally, the thermistor needs to be disconnected before the air conditioner is in operation.

[0077] In one example, please see [link to example]. Figure 1When the air conditioner is powered on or reset, the relay needs to be disconnected first to connect the thermistor PTC. Then 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 closed to disconnect the PTC resistor.

[0078] This application embodiment also provides an air conditioning control device, specifically, Figure 4 For a block diagram of the air conditioning control device provided in the embodiments of this application, please refer to [link / reference]. 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 a shutdown command is received, and to determine whether the air conditioner is in standby mode based on the fan parameters and compressor parameters.

[0080] Understandably, the judgment module 200 can also be used to perform the above step S20.

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

[0082] Understandably, the control module 210 can also be used to perform the above step S21.

[0083] Optionally, the judgment module 200 is further configured to determine that the air conditioner is in standby mode if the fan operation indicator indicates that the air conditioner's fan is in a stopped state, the compressor operation indicator indicates that the air conditioner's compressor is in a stopped state, and the compressor preheating indicator indicates that the compressor is not in a preheating state; and to determine that the air conditioner is not in standby mode if the fan operation indicator indicates that the fan is in operation, or the compressor operation indicator indicates that the compressor is in operation, or the compressor preheating indicator indicates that the compressor is in preheating state.

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

[0085] Optionally, the control module 210 is also used to control the relay according to the power-on duration 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 and connect the thermistor when the air conditioner is powered on or reset; and to control the relay to close and disconnect the thermistor when the power-on time of the air conditioner reaches a third preset time.

[0087] This application also provides a computer-readable storage medium storing a computer program thereon, which, when executed by a processor, can implement the air conditioning control method provided in this application.

[0088] While this application discloses the above information, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of this application; therefore, the scope of protection of this application shall be determined by the scope defined in the claims.
