Description

Technical Field

[0001] This application relates to the field of compressor technology, such as a control method, device, air conditioner, and storage medium for compressor preheating. Background Technology

[0002] When the compressor is in a low-temperature environment (where the ambient temperature is lower than a first set temperature), if the compressor is in standby mode, the refrigerant will gradually dissolve in the lubricating oil located at the bottom of the compressor as the temperature decreases. When the compressor restarts, a large amount of lubricating oil will leave the compressor along with the refrigerant, resulting in poor lubrication. Therefore, to reduce the amount of refrigerant dissolved in the lubricating oil, the bottom of the compressor needs to be heated.

[0003] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0004] In related technologies, the preheating device typically operates at a fixed power to heat the bottom of the compressor when it is in standby mode. The preheating device only stops operating when the compressor starts. However, if the preheating device operates at a fixed power, the bottom temperature of the compressor may exceed the target bottom temperature, resulting in energy waste. Summary of the Invention

[0005] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0006] This disclosure provides a control method, apparatus, air conditioner, and storage medium for compressor preheating, which can reduce energy waste.

[0007] In some embodiments, the control method for preheating the compressor includes: acquiring an ambient temperature; if the ambient temperature is lower than a first set temperature, acquiring a target bottom temperature and a target operating power corresponding to the ambient temperature; acquiring the bottom temperature of the compressor; if the bottom temperature of the compressor is lower than the target bottom temperature, sending the target operating power to a preheating device to trigger the preheating device to operate according to the target operating power, so that the bottom temperature of the compressor reaches the target bottom temperature.

[0008] In some embodiments, obtaining the target bottom temperature and target operating power corresponding to the ambient temperature includes: subtracting the first set temperature from the ambient temperature to obtain a first difference temperature; dividing the first difference temperature by a preset ambient temperature threshold to obtain a coefficient to be calculated; obtaining the target bottom temperature based on the coefficient to be calculated and the first set temperature; and obtaining the target operating power based on the coefficient to be calculated and a preset initial operating power.

[0009] In some embodiments, obtaining the target bottom temperature based on the coefficient to be calculated and the first set temperature includes: multiplying the coefficient to be calculated by a preset bottom temperature threshold to obtain a second difference temperature; subtracting the first set temperature from the second set temperature to obtain a third difference temperature; and determining the sum of the second difference temperature and the third difference temperature as the target bottom temperature.

[0010] In some embodiments, obtaining the target operating power based on the coefficient to be calculated and a preset initial operating power includes: multiplying the coefficient to be calculated by a preset power threshold to obtain a difference power; and determining the sum of the difference power and the initial operating power as the target operating power.

[0011] In some embodiments, after the preheating device operates at the target operating power to bring the bottom temperature of the compressor to the target bottom temperature, the method further includes: triggering the preheating device to stop operating when the bottom temperature of the compressor is equal to the target bottom temperature.

[0012] In some embodiments, before obtaining the ambient temperature, the method further includes: obtaining the standby time of the compressor; and obtaining the ambient temperature if the standby time is greater than or equal to a preset time.

[0013] In some embodiments, the control device for compressor preheating includes: a first acquisition module configured to acquire an ambient temperature; a second acquisition module configured to acquire a target bottom temperature and a target operating power corresponding to the ambient temperature when the ambient temperature is lower than a first set temperature; a third acquisition module configured to acquire the bottom temperature of the compressor; and a control module configured to send the target operating power to the preheating device when the bottom temperature of the compressor is lower than the target bottom temperature, triggering the preheating device to operate according to the target operating power so that the bottom temperature of the compressor reaches the target bottom temperature.

[0014] In some embodiments, the control device for compressor preheating includes a processor and a memory storing program instructions, the processor being configured to execute the above-described control method for compressor preheating when the program instructions are executed.

[0015] In some embodiments, the air conditioner includes the control device described above for preheating the compressor.

[0016] In some embodiments, the storage medium stores program instructions that, when executed, perform the aforementioned control method for compressor preheating.

[0017] The compressor preheating method, apparatus, air conditioner, and storage medium provided in this disclosure can achieve the following technical effects: By acquiring a target bottom temperature and target operating power corresponding to the ambient temperature when the ambient temperature is lower than a first set temperature, the target operating frequency can change with the ambient temperature. This reduces the likelihood that the compressor's bottom temperature will exceed the target bottom temperature when the preset device operates at the target operating power, thereby reducing energy waste. Furthermore, it reduces situations where the compressor's bottom temperature fails to reach the target bottom temperature due to insufficient operating power of the preheating device.

[0026] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0028] The term "correspondence" can refer to an association or binding relationship. The correspondence between A and B means that there is an association or binding relationship between A and B.

[0029] When the compressor is in standby mode, the bottom temperature of the compressor drops to the same level as the ambient temperature. If the ambient temperature is lower than a set temperature, the refrigerant inside the compressor will change from a gaseous to a liquid state, dissolving significantly in the lubricating oil at the bottom of the compressor. To reduce the amount of refrigerant dissolved in the lubricating oil, related technologies trigger a preheating device located at the bottom of the compressor casing to operate at a fixed power when the compressor is in standby mode, thereby heating the bottom of the compressor. This reduces the amount of refrigerant dissolved in the lubricating oil. However, since the ambient temperature varies, the bottom temperature of the compressor may not reach the target bottom temperature when the preheating device operates at a fixed power, or it may exceed the target bottom temperature, resulting in energy waste. This solution obtains the target bottom temperature and target operating power corresponding to the ambient temperature, allowing these parameters to change with variations in the ambient temperature. Therefore, when the preset device operates at the target power, the likelihood of the compressor bottom temperature exceeding the target bottom temperature is reduced, thus reducing energy waste. Furthermore, it can reduce the situation where the bottom temperature of the compressor cannot reach the target bottom temperature due to insufficient operating power of the preheating device.

[0030] This application can be applied to air conditioners. In some embodiments, a compressor is installed in the air conditioner.

[0031] Combination Figure 1As shown, this disclosure provides a control method for compressor preheating, including:

[0032] Step S101: The air conditioner obtains the ambient temperature.

[0033] In step S102, when the ambient temperature is lower than the first set temperature, the air conditioner obtains the target bottom temperature and target operating power corresponding to the ambient temperature.

[0034] Step S103: The air conditioner obtains the bottom temperature of the compressor.

[0035] In step S104, when the bottom temperature of the compressor is lower than the target bottom temperature, the air conditioner sends the target operating power to the preheating device, triggering the preheating device to operate at the target operating power so that the bottom temperature of the compressor reaches the target bottom temperature.

[0036] The compressor preheating control method provided in this disclosure obtains a target bottom temperature and a target operating power corresponding to the ambient temperature when the ambient temperature is lower than a first set temperature. This allows the target bottom temperature and target operating power to change with variations in the ambient temperature. Therefore, when the preset device operates at the target operating power, the likelihood of the compressor's bottom temperature exceeding the target bottom temperature is reduced, thereby reducing energy waste. Furthermore, it reduces situations where the compressor's bottom temperature fails to reach the target bottom temperature due to insufficient operating power of the preheating device.

[0037] The ambient temperature is the temperature of the space where the compressor is located. In some embodiments, the compressor is located in the living room, and the ambient temperature is the living room temperature. The first set temperature is the set ambient temperature.

[0038] Optionally, a temperature sensor is installed at the bottom of the compressor to detect the bottom temperature of the compressor. The temperature sensor is electrically connected to the air conditioner. The air conditioner obtains the bottom temperature of the compressor by receiving the bottom temperature of the compressor sent by the temperature sensor.

[0039] Optionally, the following detailed description further explains how to obtain the target bottom temperature and target operating power corresponding to the ambient temperature:

[0040] In an optional embodiment, a first difference temperature is obtained by subtracting a first set temperature from the ambient temperature. The first difference temperature is then divided by a preset ambient temperature threshold to obtain a coefficient to be calculated. The target bottom temperature is obtained based on the coefficient to be calculated and the first set temperature. The target operating power is obtained based on the coefficient to be calculated and a preset initial operating power. Here, the second set temperature, the first set temperature, and the initial operating power are all positive numbers, and the second set temperature is greater than the first set temperature. The second set temperature is the set bottom temperature of the compressor. The first difference temperature and the ambient temperature threshold are both negative integers. Thus, since the ambient temperature is lower than the first set temperature, the first difference temperature obtained by subtracting the first set temperature from the ambient temperature is negative. Simultaneously, since the ambient temperature threshold is negative, the coefficient to be calculated obtained by dividing the first difference temperature by the ambient temperature threshold is positive. Then, the target bottom temperature and target operating power corresponding to the ambient temperature are obtained using the coefficient to be calculated. This allows the target bottom temperature and target operating power to change with changes in the ambient temperature.

[0041] Further, obtaining the target bottom temperature based on the coefficient to be calculated and the first set temperature includes: multiplying the coefficient to be calculated by a preset bottom temperature threshold to obtain a second difference temperature; subtracting the first set temperature from the second set temperature to obtain a third difference temperature; and determining the sum of the second and third difference temperatures as the target bottom temperature. The bottom temperature threshold is negative. Because the lower the ambient temperature, the lower the temperature the compressor bottom can reach, even when the preheating device operates at maximum power. The second difference temperature is obtained by multiplying the coefficient to be calculated by the bottom temperature threshold. The third difference temperature is obtained by subtracting the first set temperature from the second set temperature. The sum of the second and third difference temperatures is then determined as the target bottom temperature. This allows the target bottom temperature to change with the ambient temperature. Furthermore, because the coefficient to be calculated is positive and the bottom temperature threshold is negative, the second difference temperature obtained by multiplying the coefficient to be calculated by the bottom temperature threshold is negative. Simultaneously, since both the second and first set temperatures are positive, and the second set temperature is greater than the first set temperature. Therefore, the third difference temperature obtained by subtracting the first set temperature from the second set temperature is a positive number. The sum of the second and third difference temperatures is then determined as the target bottom temperature, ensuring that the target bottom temperature decreases as the ambient temperature decreases. This makes it easier for the compressor's bottom temperature to reach the target bottom temperature.

[0042] Furthermore, the target operating power is obtained based on the coefficients to be calculated and the preset initial operating power, including: multiplying the coefficients to be calculated by a preset power threshold to obtain the differential power. The sum of the differential power and the initial operating power is determined as the target operating power. Since the lower the ambient temperature, the higher the target operating power is required for the compressor's bottom temperature to reach the target bottom temperature, obtaining the differential power using the coefficients to be calculated, and then determining the sum of the differential power and the initial operating power as the target operating power, allows the target operating power to increase as the ambient temperature decreases. This reduces the likelihood of the compressor's bottom temperature failing to reach the target bottom temperature due to insufficient preheating device operating power.

[0043] In another alternative embodiment, the target bottom temperature and target operating power corresponding to the external ambient temperature are obtained from a preset data table.

[0044] Optionally, after triggering the preheating device to operate at the target operating power to bring the compressor's bottom temperature to the target bottom temperature, the method further includes: triggering the preheating device to stop operating when the compressor's bottom temperature equals the target bottom temperature. This allows the preheating device to stop operating when the compressor's bottom temperature equals the target bottom temperature, thereby saving energy.

[0045] Combination Figure 2 As shown, this disclosure provides a control method for compressor preheating, including:

[0046] Step S201: The air conditioner obtains the ambient temperature.

[0047] In step S202, when the ambient temperature is lower than the first set temperature, the air conditioner obtains the target bottom temperature and target operating power corresponding to the ambient temperature.

[0048] Step S203: The air conditioner obtains the bottom temperature of the compressor.

[0049] In step S204, when the bottom temperature of the compressor is lower than the target bottom temperature, the air conditioner sends the target operating power to the preheating device, triggering the preheating device to operate at the target operating power so that the bottom temperature of the compressor reaches the target bottom temperature.

[0050] In step S205, when the bottom temperature of the compressor is equal to the target bottom temperature, the air conditioner triggers the preheating device to stop operating.

[0051] The compressor preheating control method provided in this disclosure obtains a target bottom temperature and a target operating power corresponding to the ambient temperature when the ambient temperature is lower than a first set temperature. This allows the target bottom temperature and target operating power to change with variations in the ambient temperature. Therefore, when the preset device operates at the target operating power, the likelihood of the compressor bottom temperature exceeding the target bottom temperature is reduced, thereby reducing energy waste. Furthermore, it reduces situations where the compressor bottom temperature fails to reach the target bottom temperature due to insufficient operating power of the preheating device. Additionally, by triggering the preheating device to stop operating when the compressor bottom temperature equals the target bottom temperature, further energy savings are achieved.

[0052] Optionally, before acquiring the ambient temperature, the method further includes acquiring the compressor's standby time. The ambient temperature is acquired only when the compressor's standby time is greater than or equal to a preset time. Therefore, even if the ambient temperature is lower than the first set temperature, the compressor's bottom temperature may only be lower than or equal to the first set temperature after the compressor has been in standby mode for a certain period. Thus, by determining whether the compressor's standby time is greater than or equal to the preset time, it is possible to determine whether the compressor's bottom temperature is less than or equal to the first set temperature. Since there is no need to heat the compressor bottom when the compressor's bottom temperature is greater than the first set temperature, acquiring the ambient temperature only when the standby time is greater than or equal to the preset time reduces unnecessary processing steps.

[0053] Combination Figure 3 As shown, this disclosure provides a control method for compressor preheating, including:

[0054] Step S301: The air conditioner obtains the standby time of the compressor.

[0055] Step S302: When the standby time of the compressor is greater than or equal to the preset time, the air conditioner obtains the ambient temperature.

[0056] In step S303, when the ambient temperature is lower than the first set temperature, the air conditioner obtains the target bottom temperature and target operating power corresponding to the ambient temperature.

[0057] Step S304: The air conditioner obtains the bottom temperature of the compressor.

[0058] In step S305, when the bottom temperature of the compressor is lower than the target bottom temperature, the air conditioner sends the target operating power to the preheating device, triggering the preheating device to operate at the target operating power so that the bottom temperature of the compressor reaches the target bottom temperature.

[0059] The compressor preheating control method provided in this disclosure acquires a target bottom temperature and a target operating power corresponding to the ambient temperature when the ambient temperature is lower than a first set temperature. This allows the target bottom temperature and target operating power to change with variations in the ambient temperature. Therefore, when the preset device operates at the target operating power, the likelihood of the compressor's bottom temperature exceeding the target bottom temperature is reduced, thereby reducing energy waste. Furthermore, it reduces situations where the compressor's bottom temperature fails to reach the target bottom temperature due to insufficient operating power of the preheating device. Additionally, by acquiring the ambient temperature only when the compressor's standby time is greater than or equal to a preset time, unnecessary processing steps are reduced.

[0060] Optionally, before obtaining the compressor's bottom temperature, the method further includes: obtaining a preset time period corresponding to the ambient temperature; obtaining the compressor's standby time; and obtaining the compressor's bottom temperature when the compressor's standby time is greater than or equal to the preset time period. The lower the ambient temperature, the shorter the preset time period corresponding to that temperature. Since the lower the ambient temperature, the faster the compressor's bottom temperature drops to the preset critical temperature, by obtaining the preset time period corresponding to the ambient temperature and determining whether the compressor's standby time is greater than or equal to the preset time period, it is possible to promptly determine whether the compressor's bottom temperature is less than or equal to the first set temperature. This allows for timely triggering of the preheating device to heat the compressor's bottom when the compressor's bottom temperature is less than or equal to the first set temperature.

[0061] Combination Figure 4 As shown, this disclosure provides a control method for compressor preheating, including:

[0062] Step S401: The air conditioner obtains the ambient temperature.

[0063] In step S402, when the ambient temperature is lower than the first set temperature, the air conditioner obtains the target bottom temperature and target operating power corresponding to the ambient temperature.

[0064] Step S403: The air conditioner obtains the preset time period corresponding to the outside ambient temperature and obtains the standby time of the compressor.

[0065] In step S404, the air conditioner obtains the bottom temperature of the compressor when the compressor's standby time is greater than or equal to a preset time period.

[0066] In step S405, when the bottom temperature of the compressor is lower than the target bottom temperature, the air conditioner sends the target operating power to the preheating device, triggering the preheating device to operate at the target operating power so that the bottom temperature of the compressor reaches the target bottom temperature.

[0067] The compressor preheating control method provided in this disclosure acquires a target bottom temperature and a target operating power corresponding to the ambient temperature when the ambient temperature is lower than a first set temperature. This allows the target bottom temperature and target operating power to change with the ambient temperature. Therefore, when the preset device operates at the target operating power, the possibility of the compressor bottom temperature exceeding the target bottom temperature is reduced, thereby reducing energy waste. Furthermore, it reduces situations where the compressor bottom temperature fails to reach the target bottom temperature due to insufficient operating power of the preheating device. Additionally, by acquiring a preset time period corresponding to the ambient temperature and determining whether the compressor's standby time is greater than or equal to the preset time period, it is possible to promptly determine whether the compressor bottom temperature is less than or equal to the first set temperature. This allows the preheating device to be triggered to heat the compressor bottom in a timely manner when the compressor bottom temperature is less than or equal to the first set temperature.

[0068] In some embodiments, the acquired ambient temperature is "-10 degrees Celsius", and it is determined that the ambient temperature "-10 degrees Celsius" is less than the first set temperature "5 degrees Celsius". The first difference temperature "-15 degrees Celsius" is obtained by subtracting the first set temperature "5 degrees Celsius" from the ambient temperature "-10 degrees Celsius". The first difference temperature "-15 degrees Celsius" is divided by a preset ambient temperature threshold "-1" to obtain a calculation coefficient "15". The calculation coefficient "15" is multiplied by a preset bottom temperature threshold "-0.6 degrees Celsius" to obtain a second difference temperature "-9 degrees Celsius". The first set temperature "5 degrees Celsius" is subtracted from the second set temperature "35 degrees Celsius" to obtain a third difference temperature "30 degrees Celsius". The sum of the second difference temperature "-9 degrees Celsius" and the third difference temperature "30 degrees Celsius" is determined as the target bottom temperature "21 degrees Celsius". The calculation coefficient "15" is multiplied by a preset power threshold "1 watt" to obtain the difference power "15 watts". The sum of the power difference "15 watts" and the preset initial operating power "10 watts" is determined as the target operating power "25 watts". The compressor bottom temperature "10 degrees Celsius" is obtained. Since the compressor bottom temperature "10 degrees Celsius" is determined to be less than the target bottom temperature "21 degrees Celsius", the target operating power "25 watts" is sent to the preheating device, triggering the preheating device to operate at the target operating power "25 watts" to bring the compressor bottom temperature to the target bottom temperature "21 degrees Celsius". This allows the target bottom temperature and target operating power to change with variations in the ambient temperature. Therefore, when the preset device operates at the target operating power, the possibility of the compressor bottom temperature exceeding the target bottom temperature is reduced. This reduces energy waste. Furthermore, it reduces situations where the compressor bottom temperature fails to reach the target bottom temperature due to insufficient preheating device operating power.

[0069] Combination Figure 5 As shown, this embodiment of the disclosure provides a control device for compressor preheating, including a first acquisition module 501, a second acquisition module 502, a third acquisition module 503, and a control module 504.

The control module 504 is configured to send the target operating power to the preheating device when the bottom temperature of the compressor is lower than the target bottom temperature, triggering the preheating device to operate according to the target operating power, so that the bottom temperature of the compressor reaches the target bottom temperature.

[0070] The compressor preheating control device provided in this embodiment acquires a target bottom temperature and a target operating power corresponding to the ambient temperature when the ambient temperature is lower than a first set temperature. This allows the target bottom temperature and target operating power to change with variations in the ambient temperature. Therefore, when the device operates at the target operating power, the likelihood of the compressor bottom temperature exceeding the target bottom temperature is reduced, thereby reducing energy waste. Furthermore, it reduces situations where the compressor bottom temperature fails to reach the target bottom temperature due to insufficient operating power of the preheating device.

[0073] Optionally, the target operating power is obtained based on the coefficient to be calculated and a preset initial operating power, including: multiplying the coefficient to be calculated by a preset power threshold to obtain the differential power.

The processor 600 can call logical instructions in the memory 601 to execute the compressor preheating control method of the above embodiment.

[0077] The compressor preheating control device provided in this embodiment acquires a target bottom temperature and a target operating power corresponding to the ambient temperature when the ambient temperature is lower than a first set temperature. This allows the target bottom temperature and target operating power to change with variations in the ambient temperature. Therefore, when the device operates at the target operating power, the likelihood of the compressor bottom temperature exceeding the target bottom temperature is reduced, thereby reducing energy waste.
