Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular, to a control method, device and electronic device for an air conditioner. Background Art

[0002] Due to the high ambient temperature in summer, the outdoor heat exchanger of the air conditioner often has poor heat dissipation during summer cooling, which increases the power consumption of the entire air conditioner. In order to reduce the power consumption of the air conditioner during summer cooling and improve indoor comfort, a spraying system can generally be installed on the air conditioner. The spraying system can spray and cool the outdoor heat exchanger, thereby optimizing the heat exchange effect of the outdoor heat exchanger and reducing the power consumption of the air conditioner.

[0004] At this time, there is a deviation between the ambient temperature detected by the ambient temperature sensor and the actual ambient temperature. Since the air conditioner is generally controlled based on the ambient temperature detected by the ambient temperature sensor, the above deviation will cause inaccurate control of the air conditioner, thereby affecting the air conditioner control strategy and reducing the user experience.

Detailed Embodiments

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Currently, due to the relatively high ambient temperature in summer, the outdoor heat exchanger of the air conditioner often has poor heat dissipation during summer cooling, thereby increasing the power consumption of the entire air conditioner. To reduce the power consumption of the air conditioner during summer cooling and improve indoor comfort, a spraying system can generally be installed on the air conditioner. The spraying system can spray and cool the outdoor heat exchanger, thereby optimizing the heat exchange effect of the outdoor heat exchanger and reducing the power consumption of the air conditioner. However, due to the angle problem during the installation of the spraying system and the different positions of the ambient temperature sensors installed on various air conditioner outdoor units, when the spraying system sprays the air conditioner outdoor unit, it often happens that the spraying liquid sprays onto the ambient temperature sensor.

[0035] At this time, there is a deviation between the ambient temperature detected by the ambient temperature sensor and the actual ambient temperature. Since the air conditioner is generally controlled based on the ambient temperature detected by the ambient temperature sensor, the above deviation will cause inaccurate control of the air conditioner, reduce the reliability of the air conditioner operation, and reduce the user experience. Based on this, the embodiments of the present invention provide a control method, device, and electronic device for an air conditioner, specifically providing a deviation control method for ambient temperature detection in the spraying mode of the air conditioner, which can improve the reliability of the air conditioner operation and increase the user experience.

[0036] To facilitate the understanding of this embodiment, first, a control method for an air conditioner disclosed in the embodiments of the present invention will be introduced in detail.

[0037] Embodiment 1:

[0038] The embodiments of the present invention provide a control method for an air conditioner, which is applied to an air conditioner. The air conditioner includes a spraying system. Refer to Figure 1 the schematic diagram of a spraying system of an air conditioner shown. The spraying system of the above air conditioner is arranged on the air conditioner outdoor unit 5. The spraying system includes: a spraying nozzle 1, a water circuit 2, a filter 3, and a water pump 4. An ambient temperature sensor 6 is arranged on the surface of the air conditioner outdoor unit. When the spraying system is turned on, the spraying nozzle can spray water mist on the air conditioner outdoor unit to optimize the heat exchange effect of the outdoor heat exchanger. If the ambient temperature sensor is arranged within the range where the water mist is sprayed, it is very likely that there is a deviation between the ambient temperature detected by the ambient temperature sensor and the actual ambient temperature.

[0039] Based on the above description, refer to Figure 2Flowchart of a control method for an air conditioner. The control method of the air conditioner includes the following steps:

[0040] Step S202: Collect the first ambient temperature before the spray system is turned on and the second ambient temperature after the spray system is turned on.

[0041] In this embodiment, the ambient temperature can be collected by an ambient temperature sensor before and after the spray system is turned on, which are referred to as the first ambient temperature and the second ambient temperature. Among them, in this embodiment, multiple ambient temperature sensors can be installed at different positions of the air conditioner, and both the first ambient temperature or the second ambient temperature can be the average value of the ambient temperatures collected by multiple ambient temperature sensors at the same time.

[0042] In this embodiment, the first ambient temperature and the second ambient temperature can be collected by a temperature sensor. Based on the first ambient temperature and the second ambient temperature, it can be determined whether there is spray water sprayed onto the temperature sensor after the spray system is turned on. For example: If the second ambient temperature is much lower than the first ambient temperature, it indicates that there is spray water sprayed onto the temperature sensor after the spray system is turned on; if the values of the second ambient temperature and the first ambient temperature are relatively close, it indicates that there is no spray water sprayed onto the temperature sensor after the spray system is turned on.

[0043] In this embodiment, the outdoor unit of the air conditioner can be turned on first. After the outdoor unit of the air conditioner works for a period of time to stabilize the ambient temperature, the first ambient temperature is collected. Then the spray system is turned on for spraying. After spraying for a period of time to stabilize the ambient temperature, the second ambient temperature is collected.

[0044] Step S204: Determine the target temperature based on the first ambient temperature, the second ambient temperature, and a preset temperature difference threshold.

[0045] In this embodiment, the target temperature used to calculate the operating frequency of the air conditioner compressor can be determined based on the first ambient temperature, the second ambient temperature, and a preset temperature difference threshold. Among them, in this embodiment, the deviation between the first ambient temperature and the second ambient temperature can be calculated. Based on the above deviation and the temperature difference threshold, it can be determined whether there is a deviation between the ambient temperature detected by the ambient temperature sensor and the actual ambient temperature. If there is no deviation, the ambient temperature collected by the sensor in real time can be used as the target temperature; if there is no deviation, the ambient temperature collected by the sensor in real time cannot be used as the target temperature. The temperature of the outdoor unit without spraying, the temperature of the position not sprayed, compensating the ambient temperature collected by the ambient temperature sensor, etc. can be used as the target temperature to eliminate the influence of the spray liquid sprayed onto the ambient temperature sensor when the spray system sprays the outdoor unit of the air conditioner.

[0046] Step S206: Determine the operating frequency of the compressor of the air conditioner based on the target temperature.

[0047] After determining the target temperature, the operating frequency of the compressor of the air conditioner can be determined based on the target temperature. Among them, in this embodiment, the corresponding relationship between the target temperature and the operating power can be preset, and the operating frequency of the compressor can be determined based on the above corresponding relationship. Generally speaking, the higher the ambient temperature, the lower the operating frequency of the compressor.

[0048] Step S208, control the compressor of the air conditioner to operate based on the operating frequency.

[0049] After determining the operating frequency of the compressor, the compressor of the air conditioner can be controlled to operate based on this operating frequency, thereby reducing the power consumption of the air conditioner during summer cooling and improving the indoor comfort.

[0050] A control method for an air conditioner provided by an embodiment of the present invention can determine the target temperature based on the first ambient temperature before the spray system is turned on, the second ambient temperature after the spray system is turned on, and a preset temperature difference threshold, determine the operating frequency of the compressor of the air conditioner based on the target temperature, and control the compressor of the air conditioner to operate based on the operating frequency. In this way, the target temperature for determining the operating frequency of the compressor can be determined according to the ambient temperature before and after the spray system is turned on, thereby eliminating the influence of the spray liquid hitting the ambient temperature sensor when the spray system sprays the outdoor unit of the air conditioner, improving the reliability of the air conditioner operation, and increasing the user experience.

[0051] Embodiment 2:

[0052] This embodiment provides another control method for an air conditioner, which is implemented on the basis of the above embodiment, as Figure 3 shown in the flowchart of another control method for an air conditioner. The control method for the air conditioner in this embodiment includes the following steps:

[0053] Step S302, collect the first ambient temperature before the spray system is turned on and the second ambient temperature after the spray system is turned on.

[0054] After the spray system is turned on, some spray liquid may hit the ambient temperature sensor. Since the temperature of the spray liquid is generally lower than the ambient temperature, there is a deviation between the ambient temperature detected by the ambient temperature sensor and the real ambient temperature.

[0055] Specifically, in this embodiment, the first ambient temperature and the second ambient temperature can be collected through the following steps: turn on the outdoor unit of the air conditioner and collect the first ambient temperature; after the outdoor unit is turned on for a preset first time, turn on the spray system of the air conditioner; after the spray system is turned on for a preset second time, collect the second ambient temperature.

[0056] After controlling the normal operation of the outdoor unit of the air conditioner, collect the first ambient temperature T1, and then collect the second ambient temperature after the outdoor unit has been turned on for the first time (which can be 20 minutes). The purpose of doing this is to keep the ambient temperature stable after the outdoor unit is turned on.

[0057] When the air conditioner meets the pre-set spray opening condition (the spray opening condition is generally greater than the pre-set temperature threshold, for example: 40°C), the spray system of the air conditioner can be turned on. Collect the second ambient temperature T2 after the outdoor unit has been turned on for the second time (which can be 5 minutes). The purpose of doing this is to keep the ambient temperature stable after the spray system is turned on.

[0058] Step S304, calculate the absolute value of the difference between the first ambient temperature and the second ambient temperature. If the absolute value is less than or equal to the pre-set temperature difference threshold, execute step S306; if the absolute value is greater than the temperature difference threshold, execute step S308.

[0059] Calculate the absolute value of the difference between the first ambient temperature and the second ambient temperature |T1 - T2|, and the temperature difference threshold can be 3°C. If |T1 - T2| ≤ 3°C, it can be considered that the detected ambient temperature deviation is small before and after the spray system is turned on; if |T1 - T2| > 3°C, it can be considered that the detected ambient temperature deviation is large before and after the spray system is turned on.

[0060] Among them, if the absolute value is greater than the temperature difference threshold, this embodiment can also prompt the user to adjust the position of the spray system, for example: if the absolute value is greater than the temperature difference threshold, send a reminder signal.

[0061] If |T1 - T2| > 3°C, it means that there is spray water spraying on the temperature sensor at this time, and there is a large error in the temperature sensor. At this time, the reminder signal can be sent to the user's terminal device (such as: a device communicating with the air conditioner such as a mobile phone, computer, tablet computer, etc.), or the reminder signal can be displayed on the panel of the air conditioner. After the user discovers the reminder signal, they can adjust the nozzle position or the temperature sensor position, and can also add a water shielding structure to the temperature sensor to improve the measurement accuracy of the temperature sensor.

[0062] Step S306, collect the ambient temperature of the air conditioner in real time, and use the ambient temperature collected in real time as the target temperature.

[0063] When |T1 - T2| ≤ 3°C, it can be considered that the sprayed liquid has not sprayed on the ambient temperature sensor, and the ambient temperature sensor is not affected by the spray. Therefore, the ambient temperature collected in real time can be used as the target temperature.

[0064] In addition, if the absolute value is less than or equal to the temperature difference threshold, in order to reduce the frequency of collecting the ambient temperature, in this embodiment, the first ambient temperature, the second ambient temperature, or the average value of the first ambient temperature and the second ambient temperature can also be used as the target temperature. That is, the first ambient temperature T1, the second ambient temperature T2, or the average value t = (T1 + T2) / 2 of the first ambient temperature and the second ambient temperature can be used as the target temperature.

[0065] Step S308, determine whether the air conditioner includes multiple parallel outdoor units. If it does, execute step S310; if not, execute step S314.

[0066] When |T2 - T1| > 3°C, it can be considered that the sprayed liquid has reached the ambient temperature sensor, and the ambient temperature detected by the sensor is affected by the liquid temperature, which may affect the control accuracy of the air conditioner. In order to eliminate the influence of the liquid temperature, the real-time collected ambient temperature cannot be used as the target temperature.

[0067] At this time, if there are parallel outdoor units for the air conditioner outdoor unit, the target temperature can be estimated through the ambient temperature of the parallel outdoor units that have not been sprayed.

[0068] Step S310, determine whether there is at least one target outdoor unit among the multiple parallel outdoor units, where the spraying units corresponding to the target outdoor unit are not turned on or the target outdoor unit has no corresponding spraying unit. If there is, execute step S312; if not, execute step S314.

[0069] In this embodiment, each outdoor unit can correspond to at least one spraying unit, or may not correspond to a spraying unit. The spraying unit may include Figure 5 the spraying nozzle 1 shown in. If there are parallel outdoor units for the air conditioner outdoor unit, it can first be determined whether there is an outdoor unit with the spraying not turned on (i.e., the target outdoor unit) among the parallel outdoor units. If there is at least one target outdoor unit, the target temperature can be determined according to the ambient temperature T3 of the target outdoor unit.

[0070] Step S312, determine the ambient temperature of each target outdoor unit, and use the maximum value of the ambient temperatures of the target outdoor units as the target temperature.

[0071] In order to maximize the spraying effect, the maximum value T3max among the ambient temperatures T3 of at least one target outdoor unit can be used as the target temperature.

[0072] Step S314, determine the opening time of the spraying system, and determine the target temperature based on the opening time of the spraying system.

[0073] If it is determined that the air conditioner does not include multiple parallel outdoor units, or there is no target outdoor unit with the spraying unit not turned on among the multiple parallel outdoor units, in this embodiment, the target temperature can be determined according to the opening time of the spraying system.

[0074] Specifically, if the air conditioner does not include multiple parallel outdoor units, in this embodiment, the first ambient temperature or the temperature at a specified position of the air conditioner can be used as the target temperature. The specified position here can be a position not sprayed by the spraying system, for example: the outlet position of the condensing pipe.

[0075] For example, if the opening time of the spraying system is less than or equal to a preset third time, the first ambient temperature is used as the target temperature; if the opening time of the spraying system is greater than the third time, the temperature at the specified position of the air conditioner is collected; wherein, the specified position is not sprayed by the spraying system; the target temperature is determined based on the temperature at the specified position.

[0076] For example, the third time can be 1 hour. It can be considered that the change in ambient temperature has an acceptable impact on control within 1 hour after the spraying system is turned on. Therefore, the first ambient temperature T1 within 1 hour can be directly used as the target temperature.

[0077] When the spraying system is turned on for 1 hour, the change in ambient temperature has a great impact on control. At this time, the first ambient temperature T1 within 1 hour is no longer directly used as the target temperature. In this embodiment, the target temperature can be determined based on the temperature at the specified position not sprayed by the spraying system.

[0078] Specifically, the specified position in this embodiment includes the bottom of the heat exchanger of the air conditioner, and the outlet temperature of the condensing pipe at the bottom of the heat exchanger of the air conditioner can be collected.

[0079] After the spraying system is turned on for 1 hour, the outlet temperature T4 of the condensing pipe at the bottom of the heat exchanger can be collected. Since there is a heat exchange temperature difference between the refrigerant in the heat exchanger and the ambient temperature, the outlet temperature T4 of the condensing pipe at the bottom of the heat exchanger is generally slightly higher than the ambient temperature. Therefore, in this embodiment, the target temperature can be calculated according to the collected outlet temperature T4 of the condensing pipe, for example: subtracting a preset temperature compensation value from the outlet temperature of the condensing pipe to obtain the target temperature.

[0080] The target temperature TX = the outlet temperature T4 of the condensing pipe - the temperature compensation value A. When the temperature compensation value A corrects the outlet temperature T4 of the condensing pipe, the value of A can be obtained based on experimental data and theoretical analysis. When the value of A is 5, under all existing working conditions, TX = T4 - 5, and the calculated ambient temperature is slightly higher than or the same as the actual ambient temperature, which can ensure that the operating frequency of the compressor does not exceed the range.

[0081] Step S316, determine the operating frequency of the compressor of the air conditioner based on the target temperature.

[0082] See Figure 4 the schematic diagram showing a correspondence between the ambient temperature and the operating frequency of the compressor shown in Figure 4It can be known that the higher the ambient temperature, the lower the maximum frequency of the compressor operation, which can ensure that the heat dissipation of the compressor variable frequency module at the corresponding ambient temperature meets the requirements and avoid the failure of the electronic control due to poor heat dissipation. Therefore, if the spraying liquid sprays onto the ambient temperature sensor, and the detected decrease in the ambient temperature is too large, the maximum allowable operating frequency of the compressor may exceed the original range, which may bring a risk of failure to the air conditioner.

[0083] Step S318, controlling the compressor of the air conditioner to operate based on the operating frequency.

[0084] The above method provided by the embodiment of the present invention can determine the target temperature based on the first ambient temperature before the spraying system is turned on, the second ambient temperature after the spraying system is turned on, and a preset temperature difference threshold, determine the operating frequency of the compressor of the air conditioner based on the target temperature, and control the compressor of the air conditioner to operate based on the operating frequency.

[0085] Among them, if the absolute value of the difference between the first ambient temperature and the second ambient temperature is less than or equal to the preset temperature difference threshold, the ambient temperature of the air conditioner is collected in real time, and the ambient temperature collected in real time can be used as the target temperature.

[0086] Among them, if the absolute value is greater than the temperature difference threshold, it is determined whether the air conditioner includes multiple parallel outdoor units; where each outdoor unit corresponds to at least one spraying unit; if so, it is determined whether there is at least one target outdoor unit among the multiple parallel outdoor units, and the spraying units corresponding to the target outdoor units are not turned on or the target outdoor unit does not have a corresponding spraying unit; if there is, the ambient temperature of each target outdoor unit is determined, and the maximum value of the ambient temperatures of the target outdoor units is used as the target temperature.

[0087] Among them, if the air conditioner does not include multiple parallel outdoor units or there is no target outdoor unit among the multiple parallel outdoor units, the opening time of the spraying system can be determined, and the target temperature can be determined based on the opening time of the spraying system.

[0088] In this way, the target temperature for determining the operating frequency of the compressor can be determined according to the ambient temperature before and after the spraying system is turned on, so as to eliminate the influence of the spraying liquid spraying onto the ambient temperature sensor when the spraying system sprays the outdoor unit of the air conditioner, improve the reliability of the operation of the air conditioner, and increase the user experience.

[0089] Embodiment Three:

[0090] Corresponding to the above method embodiment, the embodiment of the present invention provides a control device for an air conditioner, which is applied to an air conditioner.
