Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a control method, device, and dual-tower air conditioner. Background Technology

[0002] To address the drawback of traditional air conditioners' harsh airflow, an increasing number of users are opting for dual-tower air conditioners that deliver a softer breeze. In practical applications, dual-tower air conditioners default to the soft breeze function when people are just entering a room or engaged in strenuous work. However, the airflow is not sufficiently cold at these times to achieve rapid cooling, reducing user comfort and causing unnecessary energy waste. Therefore, accurately determining whether a user needs to activate the soft breeze function in a dual-tower air conditioner is crucial.

[0003] Currently, existing methods mainly rely on infrared detection of instantaneous body surface temperature to determine whether the dual-tower soft air function is activated. This method has limited detection conditions and cannot determine the user's movement status. When there are other heat-radiating objects in the room, it can easily lead to inaccurate detection results, thereby reducing the control accuracy of the dual-tower soft air function and consequently reducing user comfort. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a control method, device and dual-tower air conditioner to alleviate the above problems, improve the detection accuracy of the dual-tower soft wind function activation and the user's comfort, thereby improving the control precision of the dual-tower air conditioner.

It then calculates the target heat exchange rate based on the human body temperature to determine the human body's movement state. Based on this human body movement state, it controls whether the dual-tower soft air function is activated, improving the detection accuracy of the dual-tower soft air function activation and user comfort. At the same time, it utilizes the cooling capacity more efficiently, avoiding unnecessary energy waste in the dual-tower air conditioner, thereby improving the control accuracy of the dual-tower air conditioner.

[0012] Preferably, the above-mentioned step of controlling the dual-tower air conditioner to activate the dual-tower soft air function includes: controlling the air conditioning tower to operate in cooling mode, and simultaneously controlling the health tower to operate, so that the dual-tower air conditioner blows out soft air.

[0013] Secondly, embodiments of the present invention also provide a control device for a dual-tower air conditioner, the device comprising: a first acquisition module, configured to acquire indoor ambient temperature when the dual-tower air conditioner is running in cooling mode; a second acquisition module, configured to acquire indoor thermal imaging results if the indoor ambient temperature is greater than a preset temperature threshold; a first determination module, configured to determine the imaging position based on the thermal image if the indoor thermal imaging results contain a thermal image; wherein the imaging position is used to characterize the indoor location of the human body corresponding to the thermal image; a second determination module, configured to acquire multiple human body temperatures at the imaging position and determine a target heat exchange rate based on the multiple human body temperatures; wherein the target heat exchange rate is used to characterize the human body movement state at the imaging position; a judgment module, configured to judge whether the target heat exchange rate is not greater than a preset heat exchange rate threshold; and a soft air activation module, configured to control the dual-tower air conditioner to activate the dual-tower soft air function if so.

The target heat exchange rate is calculated based on the human body temperature to determine the human body's movement state. The dual-tower soft-wind function is then activated based on the human body's movement state. Compared to a method that solely detects human body temperature to control the activation of the dual-tower soft-wind function, this method improves the detection accuracy of the dual-tower soft-wind function and enhances user comfort. Simultaneously, it utilizes cooling capacity more efficiently, avoiding unnecessary energy waste in the dual-tower air conditioner, thereby improving the control accuracy of the dual-tower air conditioner.

[0026] 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. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Existing dual-tower air conditioners employ a dual-tower air supply design to achieve dual-tower soft wind functionality. This dual-tower design includes an air conditioning tower and a health tower. The air conditioning tower provides the air conditioning function, including but not limited to cooling or heating, while the health tower ensures the delivery of healthy and natural air. Figure 1 As shown, the air conditioning tower provides cooling, and its fan blows out cold air. Before exiting the air tower, the cold air is mixed with the natural air blown out by the fan of the health tower. For example, the cold air is mixed with 40% natural air to maintain the mixed soft air blown out by the dual-tower air conditioner at a comfortable temperature of 23°C, thereby improving the user's comfort experience. It should be noted that this embodiment of the invention focuses on describing the detection and judgment process of the dual-tower soft air function being activated. The specific structure of the air conditioning tower and the health tower can be referred to in existing dual-tower air conditioners, and this embodiment of the invention will not be described in detail here.

[0028] To address the issue of existing dual-tower air conditioners lacking the ability to accurately determine whether a user needs to activate the dual-tower soft-wind function, this invention provides a control method, device, and dual-tower air conditioner. When the indoor ambient temperature exceeds a preset temperature threshold, the imaging position and human body temperature are determined based on indoor thermal imaging results. The target heat exchange rate is then calculated based on the human body temperature to determine the human body's movement state. The dual-tower soft-wind function is then activated based on this movement state. Compared to methods that solely detect human body temperature to control the activation of the dual-tower soft-wind function, this method improves the detection accuracy of the activation of the dual-tower soft-wind function and enhances user comfort. Simultaneously, it utilizes cooling capacity more efficiently, avoiding unnecessary energy waste in the dual-tower air conditioner, thereby improving the control accuracy of the dual-tower air conditioner.

[0029] To facilitate understanding of this embodiment, the embodiments of the present invention will be described in detail below.

[0030] Example 1:

[0031] This invention provides a control method for a dual-tower air conditioner, such as... Figure 2 As shown, the method includes the following steps:

[0032] Step S202: When the dual-tower air conditioner is running in cooling mode, the indoor ambient temperature is obtained;

[0033] Specifically, when the dual-tower air conditioner is running in cooling mode, the controller of the dual-tower air conditioner obtains the indoor ambient temperature at this time. This can be done by obtaining the indoor ambient temperature detected by the temperature sensor set on the panel of the dual-tower air conditioner, or by obtaining the indoor ambient temperature sent by an electronic device. This electronic device can be a mobile phone, or a control device in a smart home, etc. The specific method of obtaining the indoor ambient temperature can be set according to the actual situation.

[0034] Step S204: If the indoor ambient temperature is greater than the preset temperature threshold, obtain the indoor thermal imaging result;

[0035] Since the most comfortable indoor temperature for the human body in summer is 18℃ to 24℃, the preset temperature threshold range is 18℃ to 24℃, preferably 24℃, but can be set according to actual conditions. When the indoor ambient temperature is higher than the preset temperature threshold, it indicates that the indoor temperature will make the user feel uncomfortable. Therefore, it is necessary to further determine whether to activate the dual-tower soft air function based on the indoor thermal imaging results to improve the accuracy of the determination to activate the dual-tower soft air function.

[0036] Furthermore, it is known that an object will not form an image when its radiant heat is the same as the temperature set by the thermal imager. The comfortable body surface temperature for humans is 35°C to 37°C; temperatures above this will produce a feeling of heat. Therefore, based on this principle, embodiments of the present invention set the temperature of the thermal imaging device, such as the thermal imager, to 35°C to 37°C, thereby determining the user's comfort level based on the indoor thermal imaging results generated by the thermal imager.

[0037] It should be noted that the indoor thermal imaging results here are the results of the thermal imaging within the preset detection range. The preset detection range can be a sector-shaped area with the indoor location of the dual-tower air conditioner as the center and a specified length as the radius, or it can be the entire indoor space where the dual-tower air conditioner is located. The specific settings can be made according to the actual situation.

[0038] Step S206: If the indoor thermal imaging results contain a thermal image, determine the imaging location based on the thermal image;

[0039] Specifically, if the indoor thermal imaging results show a thermal image, it indicates that the indoor human body temperature is greater than 37°C, which is higher than the comfort temperature. Considering that the indoor ambient temperature is greater than the preset temperature threshold, it is necessary to further test whether the dual-tower air conditioner should activate the dual-tower soft air function to avoid activating the dual-tower soft air function at this time, which would reduce the user's cooling comfort.

[0040] To further determine whether the dual-tower soft air function is activated, the controller determines the imaging position based on the thermal image. The imaging position is used to characterize the indoor location of the human body corresponding to the thermal image. Therefore, based on the thermal image in the indoor thermal imaging results, the number of people in the room and the position of each person, i.e., the imaging position, can be determined to determine the human body's movement state at each imaging position, thereby improving the detection accuracy of whether the dual-tower soft air function is activated.

[0041] It should be noted that the controller can directly determine the number of people in the room based on thermal imaging. Specifically, it determines the corresponding imaging position based on each thermal image. Existing image analysis and processing technologies can be referenced, and the embodiments of the present invention will not be described in detail here.

[0042] Step S208: Obtain multiple human body temperatures at the imaging location, and determine the target heat exchange rate based on the multiple human body temperatures;

[0043] After determining the imaging position, for each imaging position, the controller can also obtain multiple body temperatures T of the same person at that imaging position through an infrared temperature sensor, and calculate the target heat exchange rate of the person based on the multiple body temperatures T. The target heat exchange rate is used to characterize the human motion state at the imaging position. Therefore, based on the multiple body temperatures at the imaging position, the human motion state can be judged more accurately, so as to further determine whether to activate the dual-tower soft wind function based on the human motion state, thereby improving the control accuracy of the dual-tower soft wind function.

[0044] Step S210: Determine whether the target heat exchange rate is not greater than the preset heat exchange rate threshold.

[0045] Specifically, since the heat exchange rate of an adult in a normal static or slightly active state is 200kcal / min to 500kcal / min, and the heat exchange rate in other active states is 500kcal / min to 1000kcal / min, the preset heat exchange rate threshold is preferably 500kcal / min. Therefore, by using the target heat exchange rate at the imaging position and the preset heat exchange rate threshold, the corresponding human motion state can be detected, so as to determine whether to activate the dual-tower soft wind function based on the user's human motion state, thereby improving the detection accuracy and control accuracy of whether the dual-tower soft wind function is activated.

[0046] Step S212: If yes, control the dual-tower air conditioner to turn on the dual-tower soft air function.

[0047] Specifically, when the target heat exchange rate is not greater than the preset heat exchange rate threshold, it indicates that the user is in a static or lightly moving state. At this time, the user's demand for cooling is not high, and the controller controls the dual-tower air conditioner to turn on the dual-tower soft air function to prevent cold air from blowing directly, thereby improving the user's air conditioning comfort while meeting the cooling demand.

[0048] The control method for a dual-tower air conditioner provided in this invention determines the imaging position and human body temperature based on indoor thermal imaging results when the indoor ambient temperature is higher than a preset temperature threshold. It then calculates the target heat exchange rate based on the human body temperature to determine the human body's movement state. Based on this movement state, the dual-tower soft-wind function is activated. Compared to a method that solely detects human body temperature to control the activation of the dual-tower soft-wind function, this method improves the detection accuracy of the activation of the dual-tower soft-wind function and enhances user comfort. Simultaneously, it utilizes cooling capacity more efficiently, avoiding unnecessary energy waste in the dual-tower air conditioner.

[0049] In one embodiment, the method further includes: if the indoor ambient temperature is not greater than a preset temperature threshold, controlling the dual-tower air conditioner to turn on the dual-tower soft air function.

[0050] Specifically, when the indoor ambient temperature is not higher than the preset temperature threshold, it means that the room temperature is low. Since it is summer, the lowest set temperature of the dual-tower air conditioner is 16℃, and the corresponding lowest room temperature is about 17℃ to 18℃. Therefore, the room temperature at this time is also considered to be within the comfortable temperature range for the human body. That is, the indoor ambient temperature at this time meets the user's cooling needs. At this time, controlling the dual-tower air conditioner to turn on the dual-tower soft wind function can prevent cold air from blowing directly, and improve the user's air conditioning comfort while meeting the cooling needs.

[0051] In summary, based on the indoor ambient temperature and the preset temperature threshold, it is possible to analyze whether the indoor temperature is within the user's comfortable temperature range. Based on the analysis results, it is possible to determine whether the dual-tower soft air function is activated, thereby ensuring the accuracy of the detection of whether the dual-tower soft air function is activated.

[0052] In one embodiment, the method further includes: if no thermal image is found in the indoor thermal imaging results, controlling the dual-tower air conditioner to activate the dual-tower soft air function.

[0053] Specifically, when no thermal image is found in the indoor thermal imaging results, it means that the indoor human body temperature does not exceed 37℃. If it is between 35℃ and 37℃, although the indoor ambient temperature is higher than the preset temperature threshold, the heat dissipation is good, and the human body temperature of the user in the room is within a relatively comfortable range. In other words, the dual-tower air conditioner has basically met the user's cooling needs. The controller controls the dual-tower air conditioner to turn on the dual-tower soft wind function to avoid direct cold air blowing, thereby improving the user's air conditioning comfort while meeting the cooling needs.

[0054] In one embodiment, the method further includes: if the target heat exchange rate is greater than a preset heat exchange rate threshold, controlling the dual-tower air conditioner to continue operating in cooling mode, and adjusting the air guide vanes of the dual-tower air conditioner to deliver air to the imaging position.

[0055] Specifically, when the target heat exchange rate is greater than the preset heat exchange rate threshold, it indicates that the user is in motion, such as in a moderate or heavy motion state. At this time, the user has a greater demand for cooling capacity, and the dual-tower air conditioner should first meet the user's cooling needs, that is, control the dual-tower air conditioner to continue operating in cooling mode.

[0056] Furthermore, to further improve the cooling comfort for users during operation, the controller also adjusts the air guide vanes of the dual-tower air conditioner to deliver airflow to the imaging position where the user is located. Simultaneously, it avoids direct airflow onto users in other positions during continued cooling operation, ensuring a comfortable air conditioning experience for those in other locations. These other locations include positions where no thermal image has been generated or imaging positions where the target heat exchange rate does not exceed a preset heat exchange rate threshold. Therefore, by adjusting the air guide vanes to deliver airflow, the air conditioning experience for users in different comfort states is guaranteed, improving the control precision and intelligence of the dual-tower air conditioner.

[0057] In one embodiment, the human body temperature includes sequentially detected first human body temperature T1, second human body temperature T2, third human body temperature T3, and fourth human body temperature T4; step S208 further includes:

[0058] (A1) The first heat exchange rate is calculated based on the first human body temperature and the second human body temperature, as well as the corresponding first detection time interval; specifically, the first heat exchange rate η1 = (T1-T2) / t1; where the first human body temperature T1 represents the human body temperature at the first detection, the second human body temperature T2 represents the human body temperature at the second detection, and t1 represents the time interval between the first and second detections.

[0059] (A2) The second heat exchange rate is calculated based on the third and fourth human body temperatures and the corresponding second detection time interval; specifically, the second heat exchange rate η2 = (T3-T4) / t2; where the third human body temperature T3 represents the human body temperature at the third detection, the fourth human body temperature T4 represents the human body temperature at the fourth detection, and t2 represents the time interval between the third and fourth detections.

[0060] It should be noted that the controller can simultaneously calculate the first heat exchange rate η1 and the second heat exchange rate η2 after acquiring multiple human body temperatures, or it can calculate them sequentially according to the detection time. For example, after acquiring the first human body temperature T1 and the second human body temperature T2, the first heat exchange rate η1 is calculated and recorded; subsequently, the second heat exchange rate η2 is calculated based on the acquired third human body temperature T3 and fourth human body temperature T4; and at this time, the target heat exchange rate is calculated based on the first heat exchange rate η1 and the second heat exchange rate η2.

[0061] (A3) The target heat exchange rate is obtained by averaging the first heat exchange rate and the second heat exchange rate.

[0062] Specifically, the target heat exchange rate η = (η1 + η2) / 2; by averaging the target heat exchange rate, the detection accuracy of human motion at the imaging position is improved, thereby improving the detection accuracy of whether the dual-tower soft wind function is on, and further improving the control accuracy of the dual-tower air conditioner.

[0063] In one implementation, since the dual-tower air conditioner includes an air conditioning tower and a health tower, when the dual-tower air conditioner is running in cooling mode, the controller controls the air conditioning tower to operate in cooling mode as well. Furthermore, when the dual-tower air conditioner activates its soft air function, the controller controls the air conditioning tower to operate in cooling mode while simultaneously controlling the health tower to operate, so that the dual-tower air conditioner blows soft air, thereby improving the control precision and intelligence of the dual-tower air conditioner.

[0064] In summary, the control method for a dual-tower air conditioner provided in this embodiment of the invention mainly determines whether to activate the dual-tower soft air function through four stages of detection; specifically as follows: ① When the dual-tower air conditioner is running in cooling mode, it determines whether to enter the logic of detecting whether to activate the dual-tower soft air function based on the indoor ambient temperature; ② It activates the thermal imaging detection mode for the room and determines the distribution of people in the room and the imaging position through the indoor thermal imaging results; ③ It detects the temperature of multiple people at the imaging position and calculates the corresponding target heat exchange rate to determine the human movement state, thereby improving the detection accuracy of whether to activate the dual-tower soft air function and ensuring user comfort; ④ If cooling operation continues, it adjusts the air delivery position of the air guide to direct the air conditioner to the corresponding imaging position, ensuring the air conditioning experience for users with different comfort levels, while also avoiding energy waste caused by the dual-tower air conditioner and improving the utilization rate of cooling capacity.

[0065] Example 2:

[0066] Based on the above method embodiments, this invention also provides another control method for a dual-tower air conditioner, which focuses on describing the control process of the dual-tower air conditioner. Figure 3 As shown, the method includes the following steps:

[0067] Step S302: The dual-tower air conditioner is started and running;

[0068] Step S304: Determine whether the operating mode is cooling mode; if yes, proceed to step S308; otherwise, proceed to step S306.

[0069] Step S306: Control the dual-tower air conditioner to operate according to the corresponding operating mode; wherein, the operating mode includes, but is not limited to, heating mode, air supply mode, etc., and can be set according to the actual situation.

[0070] Step S308: Obtain the indoor ambient temperature Tao;

[0071] Step S310: Determine whether Tao ≤ 24℃; that is, determine whether the indoor ambient temperature Tao is not greater than the preset temperature threshold, which is 24℃. If yes, proceed to step S312; otherwise, proceed to step S314.

[0072] Step S312: Control the dual-tower air conditioner to turn on the dual-tower soft wind function, and after running for 1 hour, return to step S308 to re-detect the indoor ambient temperature Tao.

[0073] Specifically, when Tao ≤ 24℃, it indicates that the room temperature is low and within the human comfort temperature range. This means that the indoor ambient temperature meets the user's cooling needs. At this time, controlling the dual-tower air conditioner to turn on the dual-tower soft air function can prevent cold air from blowing directly on the room. In addition to meeting the cooling needs, it also improves the user's air conditioning comfort. Furthermore, after the dual-tower soft air function has been running for 1 hour, the indoor ambient temperature Tao is re-detected. Based on the indoor ambient temperature Tao, the logic for re-determining whether to enter the detection and activation of the dual-tower soft air function is re-evaluated, thus improving the control accuracy of the dual-tower soft air function.

[0074] Step S314: Obtain indoor thermal imaging results; specifically, when Tao > 24℃, it indicates that the indoor temperature at this time will make the user feel uncomfortable. Further judgment is needed based on the indoor thermal imaging results to determine whether to turn on the dual-tower soft wind function, so as to improve the accuracy of the judgment on turning on the dual-tower soft wind function.

[0075] Step S316: Determine whether a thermal image exists in the indoor thermal imaging results; if not, proceed to step S318; if yes, proceed to step S320.

[0076] Step S318: Control the dual-tower air conditioner to turn on the dual-tower soft wind function, and after running for 1 hour, return to step S308 to re-detect the indoor ambient temperature Tao.

[0077] Specifically, when no thermal image is found in the indoor thermal imaging results, it indicates that the indoor human body temperature does not exceed 37℃. If it is between 35℃ and 37℃, although the indoor ambient temperature is higher than the preset temperature threshold, heat dissipation is good, and the human body temperature of the users in the room is within a relatively comfortable range. In other words, the dual-tower air conditioner has basically met the user's cooling needs. The controller controls the dual-tower air conditioner to turn on the dual-tower soft wind function to avoid direct cold air blowing, thereby improving the user's air conditioning comfort while meeting the cooling needs. Furthermore, after the dual-tower soft wind function has been running for 1 hour, the indoor ambient temperature Tao is re-detected so that the logic for detecting and turning on the dual-tower soft wind function can be re-determined based on the indoor ambient temperature Tao, thereby improving the control accuracy of the dual-tower soft wind function.

[0078] Step S320: Determine the imaging position A based on the thermal image;

[0079] Specifically, when the indoor thermal imaging results contain a thermal image, the human body temperature is higher than the comfort temperature. It is also necessary to determine the imaging position based on the thermal image. For ease of explanation, imaging position A is used as an example. The user's movement state is determined based on the heat exchange rate at the imaging position, so as to further determine whether to activate the dual-tower soft wind function based on the user's movement state, thereby improving the detection accuracy and control accuracy of the dual-tower soft wind function.

[0080] Step S322: Obtain the first human body temperature T1 within the imaging location A;

[0081] Step S324: Obtain the second human body temperature T2 within the imaging location A; wherein the detection interval between the first human body temperature T1 and the second human body temperature T2 is 5 minutes.

[0082] Step S326: Calculate the first heat exchange rate η1 based on T1 and T2;

[0083] Step S328: Obtain the temperature T3 of the third human body within the imaging location A;

[0084] It should be noted that, in order to determine whether the person at imaging location A is moving intermittently or continuously, the above detection process is repeated after an interval of 10 minutes. That is, the interval between the third human body temperature T3 and the second human body temperature T2 is preferably 10 minutes.

[0085] Step S330: Obtain the fourth human body temperature T4 within the imaging location A; wherein the detection interval between the fourth human body temperature T4 and the third human body temperature T3 is 5 minutes.

[0086] Step S332: Calculate the second heat exchange rate η2 based on T3 and T4;

[0087] Step S334: The target heat transfer rate η is calculated based on η1 and η2; therefore, by averaging the target heat transfer rate η, the accuracy of judging the motion state of the person at imaging location A is improved.

[0088] Step S336: Determine whether η≤500 is satisfied; that is, determine whether the target heat transfer rate η at imaging position A is not greater than the preset heat transfer rate threshold of 500. If yes, proceed to step S338; otherwise, proceed to step S340.

[0089] Step S338: Control the dual-tower air conditioner to turn on the dual-tower soft air function, and run it for 1 hour before returning to step S322;

[0090] Specifically, when η≤500, it indicates that the person at imaging position A is in a static or slightly moving state. At this time, the user's demand for cooling is not large, and the controller controls the dual-tower air conditioner to turn on the dual-tower soft wind function to prevent cold air from blowing directly, thereby improving the user's air conditioning comfort while meeting the cooling demand.

[0091] Furthermore, after the dual-tower soft wind function has been running for 1 hour, the temperature of multiple human bodies at imaging position A is re-detected, and the target heat exchange rate η is recalculated based on the multiple human body temperatures. In order to re-detect the user's movement status based on the target heat exchange rate η, the dual-tower soft wind function can be controlled in a timely manner based on the user's movement status. This not only improves the control accuracy of the dual-tower air conditioner, but also ensures the user's air conditioning comfort.

[0092] Step S340: Control the dual-tower air conditioner to continue operating in cooling mode;

[0093] Step S342: Adjust the air guide strips of the dual-tower air conditioner to supply air to the imaging position A, and return to step S322 after running for 1 hour.

[0094] Specifically, when η > 500, it indicates that the user is in motion, such as moderate or heavy motion. In this case, the user has a greater demand for cooling, and the dual-tower air conditioner should first meet the user's cooling needs, i.e., control the dual-tower air conditioner to continue operating in cooling mode. At the same time, in order to further improve the user's cooling comfort during operation, the controller also adjusts the air guide vanes of the dual-tower air conditioner to deliver air to the imaging position where the user is located.

[0095] Furthermore, after the dual-tower air conditioner has been running for 1 hour in cooling mode, the temperatures of multiple human bodies at imaging position A are re-detected, and the target heat exchange rate η is recalculated based on these temperatures. This allows for the re-detection of the user's movement status based on the target heat exchange rate η, enabling timely control of the dual-tower air conditioner based on the user's movement status. This not only improves the control accuracy of the dual-tower air conditioner but also ensures the user's comfort.

[0096] In summary, the control method for a dual-tower air conditioner provided in this embodiment of the invention, in cooling mode, jointly detects whether the dual-tower soft air function is activated based on the indoor ambient temperature, indoor thermal imaging results, and heat exchange rate. Compared with the method of controlling the activation of the dual-tower soft air function solely by detecting human body temperature, this method improves the detection accuracy of the activation of the dual-tower soft air function and enhances user comfort. At the same time, it utilizes the cooling capacity more efficiently, avoiding unnecessary energy waste in the dual-tower air conditioner.
