Description

Technical Field

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

[0002] Air conditioning systems, consisting of water-cooling and fresh air systems, require high room airtightness. Therefore, the opening and closing status of windows and doors must be detected. Traditional air conditioning systems use magnetic induction to detect the opening and closing status of windows and doors. However, magnetic induction is costly, requiring at least two window magnetic sensors per window, and is prone to installation errors and high failure rates. Consequently, the air conditioning system cannot be accurately adjusted and controlled when the opening and closing status of windows and doors is not accurately determined, thus affecting the user's comfort experience. Summary of the Invention

[0003] The main objective of this invention is to provide an air conditioning control method, an air conditioner, and a computer-readable storage medium, aiming to solve the technical problem of how to accurately adjust and control the air conditioning system based on the opening and closing status of doors and windows.

[0004] To achieve the above objectives, the present invention provides an air conditioning control method, the air conditioning control method comprising the following steps:

[0005] The indoor temperature and the door and window temperature are obtained, a first difference between the indoor temperature and the door and window temperature is determined, and it is determined whether the first difference is greater than or equal to a preset first temperature difference threshold.

[0006] If the first difference is greater than or equal to a preset first temperature difference threshold, then determine whether the first difference is greater than or equal to the current dew point temperature difference;

[0007] If the first difference is greater than or equal to the current dew point temperature difference, then reduce the fresh air volume and increase the exhaust air volume.

[0008] Optionally, before the step of determining the first difference between the indoor temperature and the door / window temperature, the method includes:

[0009] Obtain the outdoor ambient temperature and determine a second difference between the outdoor ambient temperature and the indoor temperature;

[0010] Determine whether the second difference is less than or equal to a preset second temperature difference threshold;

[0011] If the second difference is greater than the preset second temperature difference threshold, then the step of determining the first difference between the indoor temperature and the door and window temperature is performed.

[0012] Optionally, after the step of determining whether the first difference is greater than or equal to a preset first temperature difference threshold, the method further includes:

[0013] If the first difference is greater than or equal to a preset first temperature difference threshold, then output a prompt message indicating that the doors and windows are open; or

[0014] If the first difference is less than the preset first temperature difference threshold, a prompt message indicating that the doors and windows are closed will be output.

[0015] Optionally, after the step of reducing the fresh air volume and increasing the exhaust air volume, the following steps are included:

[0016] The first duration for which the first difference is greater than or equal to the current dew point temperature difference is calculated, and it is determined whether the first duration is greater than or equal to a preset first duration threshold.

[0017] If the first duration is greater than or equal to a preset first duration threshold, the dehumidification mode is activated to dehumidify the room.

[0018] Optionally, after the step of determining whether the first duration is greater than or equal to a preset first duration threshold, the method further includes:

[0019] If the first duration is greater than or equal to a preset first duration threshold, an indoor condensation risk warning message will be output.

[0020] Optionally, after the step of activating the dehumidification mode to dehumidify the room, the following steps are included:

[0021] Real-time monitoring of indoor humidity, and statistical analysis of the second duration during which the indoor humidity is greater than or equal to a preset humidity threshold;

[0022] Determine whether the second duration is greater than or equal to a preset second duration threshold;

[0023] If the second duration is greater than or equal to the preset second duration threshold, an alarm will be issued and the system will stop operating.

[0024] Optionally, after the step of determining whether the second duration is greater than or equal to a preset second duration threshold, the method further includes:

[0025] If the second duration is less than the preset second duration threshold, the dehumidification mode is turned off, and the step of determining the first duration of the first difference being greater than or equal to the current dew point temperature difference is executed.

[0026] Optionally, the air conditioning control method is applied to a full-radiation air conditioning system, which includes at least: a chiller, a fresh air unit, a wired controller, multiple temperature sensors, and multiple humidity sensors; the multiple temperature sensors and multiple humidity sensors are respectively installed in the indoor doors and windows and the wired controller.

[0027] In addition, to achieve the above objectives, the present invention also provides an air conditioner, including a processor, a memory, and an air conditioning control program stored in the memory that can be executed by the processor, wherein when the air conditioning control program is executed by the processor, it implements the steps of the air conditioning control method as described above.

[0028] The present invention also provides a computer-readable storage medium storing an air conditioning control program, wherein when the air conditioning control program is executed by a processor, it implements the steps of the air conditioning control method described above.

[0029] The air conditioning control method in this invention obtains indoor temperature and door / window temperature, determines a first difference between the indoor temperature and the door / window temperature, and judges whether the first difference is greater than or equal to a preset first temperature difference threshold. This step allows for the use of temperature sensors at doors and windows to replace the traditional method of installing door and window magnetic sensors, which is costly, to determine how to regulate the indoor air environment, significantly reducing user costs. Furthermore, the step of judging whether the first difference is greater than or equal to the current dew point temperature difference if the first difference is greater than or equal to the preset first temperature difference threshold not only identifies the open state of doors and windows but also accurately judges possible condensation when doors and windows are open. Finally, the step of reducing the fresh air volume and increasing the exhaust air volume if the first difference is greater than or equal to the current dew point temperature difference ensures that even when doors and windows are open, the outdoor air brought in by the open doors and windows can be promptly exhausted outdoors, preventing drastic changes in indoor temperature caused by outdoor wind and indoor condensation from affecting the operation of the air conditioning system and the user's comfort experience. Reducing the fresh air volume also reduces unnecessary energy consumption and waste. Attached Figure Description

[0038] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0039] Overview of the technical solution of this invention:

[0040] This invention can be applied to various air conditioning systems and air conditioners, including full radiant air conditioning systems. It primarily obtains indoor, door / window, and outdoor temperatures by installing temperature and humidity sensors (or combined temperature and humidity sensors) at any or designated locations near doors, windows, and the remote controller. The open / closed status of doors and windows is determined by comparing the indoor and door / window temperatures, and the risk of indoor condensation is also determined by comparing the indoor and outdoor temperatures. Once doors and windows are determined to be open, to prevent outdoor air from entering the room and negatively impacting the air conditioning system and indoor air quality, the indoor air environment is precisely adjusted by reducing fresh air intake, increasing exhaust air, and dehumidifying to maintain comfort. The system also promptly alerts users to the open / closed status of doors and windows, allowing them to take appropriate action when doors and windows are open, significantly saving energy and extending the lifespan of the air conditioner.

[0041] This invention provides an air conditioner. The air conditioner can be any type, such as a wall-mounted air conditioner, a cabinet air conditioner, a portable air conditioner, a window air conditioner, a multi-split air conditioner, or a ceiling-mounted air conditioner, and there are no restrictions on this.

[0042] like Figure 1 As shown, Figure 1 This is a schematic diagram of the hardware operating environment of the air conditioner involved in the embodiments of the present invention.

[0043] like Figure 1As shown, the air conditioner may include: a processor 1001, such as a CPU; a network interface 1004; a user interface 1003; a memory 1005; and a communication bus 1002. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display or an input unit such as a control panel; optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory 1005 may be high-speed RAM or non-volatile memory, such as a disk drive. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001. The memory 1005, as a computer storage medium, may include an air conditioning control program.

[0044] Those skilled in the art will understand that Figure 1 The hardware structure shown does not constitute a limitation on the device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0045] Continue to refer to Figure 1 , Figure 1 The memory 1005, which is a computer-readable storage medium, may include an operating system, a user interface module, a network communication module, and an air conditioning control program.

[0046] exist Figure 1 In this embodiment, the network communication module is mainly used to connect to the server and communicate with the server for data; while the processor 1001 can call the air conditioning control program stored in the memory 1005 and execute the steps in the following embodiments.

[0047] Based on the hardware structure of the controller described above, various embodiments of the air conditioning control method of the present invention are proposed.

[0048] This invention provides an air conditioning control method.

[0049] Please refer to Figure 2 , Figure 2 This is a flowchart illustrating a first embodiment of the air conditioning control method of the present invention; in the first embodiment of the present invention, the air conditioning control method includes the following steps:

[0050] Step S10: Obtain the indoor temperature and the door and window temperature, determine the first difference between the indoor temperature and the door and window temperature, and determine whether the first difference is greater than or equal to a preset first temperature difference threshold.

[0051] Specifically, in this embodiment, the air conditioning control method can be applied to a full-radiation air conditioning system or other air conditioning systems, referring to... Figure 6 , Figure 6 This is a schematic diagram of the framework structure of the full-radiation air conditioning system involved in the air conditioning control method of the present invention; the full-radiation air conditioning system includes at least: a chiller unit, a fresh air unit, a wired controller, multiple temperature sensors, and multiple humidity sensors; the multiple temperature sensors and multiple humidity sensors are respectively installed in the indoor doors and windows and the wired controller. (Refer to...) Figure 7 , Figure 7 This is a schematic diagram of the fresh air unit structure of the full-radiation air conditioning system involved in the air conditioning control method of the present invention. The fresh air unit includes at least: a fresh air fan 301, an exhaust fan 302, a fresh air valve 303, an internal circulation valve 304, an exhaust valve 305, a multi-functional sensor 306, a temperature and humidity sensor 307, a humidifying membrane 308, as well as a system (dehumidification-heat recovery system) and an outdoor unit.

[0052] The specific distribution of the multiple temperature sensors and multiple humidity sensors indoors can be as follows: To determine the temperature of doors and windows (the temperature of the door or window), one or more temperature sensors and one or more humidity sensors can be set at a preset distance above each door or window indoors. In practical applications, setting one temperature sensor and one humidity sensor for each door or window is generally sufficient. The preset distance can be set according to actual needs. For example, a temperature sensor can be set at any position or in the middle of the window, 5 cm from the upper edge, and a humidity sensor can be set immediately next to it. Similarly, this can be done for doors. To determine the indoor temperature, one temperature sensor and one humidity sensor can be set at any position within a preset circumferential area of ​​the wired controller. In addition, the above-mentioned temperature and humidity sensors can be unified into a temperature and humidity sensor (a comprehensive sensor with temperature and humidity detection functions), that is, only one temperature and humidity sensor needs to be set around the doors, windows, and wired controller.

[0053] Furthermore, the total radiant air conditioning system may also include a dew point sensor, which can be used to directly detect the current dew point temperature indoors and thus determine the current dew point temperature difference. This improves the efficiency of determining the current dew point temperature and the current dew point temperature difference.

[0054] Based on the aforementioned full radiant air conditioning system, it can accurately obtain the indoor temperature and door and window temperature. Compared with the traditional method of setting up window magnetic sensors and door magnetic sensors at doors and windows, the ordering cost of temperature and humidity sensors is much lower than that of window magnetic sensors and door magnetic sensors. Moreover, the installation cost of temperature and humidity sensors is also much lower than that of window magnetic sensors and door magnetic sensors. Furthermore, it is less likely to encounter installation problems that reduce the accuracy of the sensors.

[0055] When the radiant air conditioning system is turned on, after obtaining the indoor temperature and the door / window temperature, the indoor temperature is subtracted from the door / window temperature, or vice versa, and the absolute value is taken to obtain the first difference between the two. The preset first temperature difference threshold is a positive value equal to or close to 0, such as 0℃, 0.5℃, or 1℃. The specific first temperature difference threshold can be set according to actual needs. By judging the magnitude of the first difference and the first temperature difference threshold, it can be determined whether the doors and windows are open. When the doors and windows are closed, the door / window temperature is approximately equal to the indoor temperature, meaning the first difference is less than the first temperature difference threshold. When the doors and windows are open, the temperature difference between the door / window temperature and the indoor temperature will be larger, meaning the first difference is greater than or equal to the first temperature difference threshold.

[0056] In one embodiment, prior to the step of determining the first difference between the indoor temperature and the door / window temperature, the air conditioning control method further includes:

[0057] Step a: Obtain the outdoor ambient temperature and determine the second difference between the outdoor ambient temperature and the indoor temperature;

[0058] The outdoor ambient temperature can be obtained by detecting the outdoor unit of the air conditioning system or by obtaining the real-time temperature from the weather forecast. The real-time temperature from the weather forecast and the outdoor ambient temperature detected by the outdoor unit can complement each other, but the outdoor ambient temperature detected by the outdoor unit has the highest priority. The real-time temperature from the weather forecast can only be used as the outdoor ambient temperature when the outdoor unit has a detection failure.

[0059] The second difference can be obtained by subtracting the indoor temperature from the outdoor temperature or vice versa, and then taking the absolute value.

[0060] Step b: Determine whether the second difference is less than or equal to a preset second temperature difference threshold;

[0061] The second temperature difference threshold here is also a positive value equal to or close to 0, but it can be the same as or different from the value corresponding to the first temperature difference threshold mentioned above, and can be set according to actual needs.

[0062] Step c: If the second difference is greater than the preset second temperature difference threshold, then the step of determining the first difference between the indoor temperature and the door and window temperature is executed.

[0063] If the second temperature difference is greater than the second temperature difference threshold, it means that the air conditioning system has been running for a sufficient amount of time, and a significant temperature difference has been generated between the indoor and outdoor areas. Then, the step of determining the first difference between the indoor temperature and the door and window temperatures will begin.

[0064] If the second temperature difference is less than the second temperature difference threshold, it means that the air conditioning system has just been started or has been started for a short time. At this time, the air conditioning system will operate normally according to the user's settings and does not need to execute the first difference step between the set indoor temperature and the door and window temperature.

[0065] This embodiment avoids the common situation where the air conditioning system makes judgments about the opening and closing of doors and windows based on indoor and door / window temperatures as soon as it is turned on, which can easily lead to misjudgments. It improves the reliability and accuracy of identifying the opening and closing status of doors and windows and prevents unnecessary trouble for users.

[0066] In another embodiment, after the step of determining whether the first difference is greater than or equal to a preset first temperature difference threshold, the air conditioning control method further includes:

[0067] Step d: If the first difference is greater than or equal to a preset first temperature difference threshold, then output a prompt message indicating that the doors and windows should be opened; or

[0068] Step e: If the first difference is less than the preset first temperature difference threshold, then output a prompt message indicating that the doors and windows are closed.

[0069] If the first temperature difference is greater than or equal to a preset first temperature difference threshold, a prompt message indicating that doors and windows are open can be displayed on the display panel of the indoor unit of the air conditioning system. This can also be achieved through voice announcements via the indoor unit's speaker, regular flashing of the indoor unit's lights, or push notifications to a mobile terminal connected to the air conditioning system. This timely and convenient reminder helps users ensure that doors and windows are properly closed, thus preventing energy waste caused by open doors and windows.

[0070] If the first difference is less than the first temperature difference threshold, it means that the doors and windows are tightly closed. The indoor unit display panel can then output a prompt message indicating that the doors and windows are closed. This prompt message can be presented in the form of character codes or graphics.

[0071] Step S20: If the first difference is greater than or equal to a preset first temperature difference threshold, then determine whether the first difference is greater than or equal to the current dew point temperature difference.

[0072] If the first difference is greater than or equal to the first temperature difference threshold, it indicates that the doors and windows have been opened and the air conditioning system has been running for a certain period of time to cool the room. Furthermore, considering that there is a greater risk of condensation when the doors and windows are open, this invention needs to further determine whether condensation will occur indoors by judging the magnitude of the first difference and the current dew point temperature difference.

[0073] Step S30: If the first difference is greater than or equal to the current dew point temperature difference, then reduce the fresh air volume and increase the exhaust air volume.

[0074] If the initial temperature difference is greater than or equal to the current dew point temperature difference, the risk of indoor condensation and the operational risk of the air conditioning system will gradually increase over time. Therefore, to avoid these risks initially, when the initial temperature difference is greater than or equal to the current dew point temperature difference, reducing the fresh air volume and increasing the exhaust air volume can efficiently and promptly exhaust outdoor air entering the room through doors and windows while simultaneously reducing the fresh air volume provided by the air conditioning system. This avoids or prolongs the duration of indoor condensation and reduces the operational risk of the air conditioning system, while also preventing unnecessary energy waste and giving users time to close doors and windows, which is particularly suitable for situations where users leave without properly closing doors and windows.

[0075] The air conditioning control method in this invention obtains indoor temperature and door / window temperature, determines a first difference between the indoor temperature and the door / window temperature, and judges whether the first difference is greater than or equal to a preset first temperature difference threshold. This step allows for the use of temperature sensors at doors and windows to replace the traditional method of installing door and window magnetic sensors, which is costly, to determine how to regulate the indoor air environment, significantly reducing user costs. Furthermore, the step of judging whether the first difference is greater than or equal to the current dew point temperature difference if the first difference is greater than or equal to the preset first temperature difference threshold not only identifies the open state of doors and windows but also accurately judges possible condensation when doors and windows are open. Finally, the step of reducing the fresh air volume and increasing the exhaust air volume if the first difference is greater than or equal to the current dew point temperature difference ensures that even when doors and windows are open, the outdoor air brought in by the open doors and windows can be promptly exhausted outdoors, preventing drastic changes in indoor temperature caused by outdoor wind and indoor condensation from affecting the operation of the air conditioning system and the user's comfort experience. Reducing the fresh air volume also reduces unnecessary energy consumption and waste.

[0076] Please refer to Figure 3 , Figure 3 This is a flowchart illustrating a second embodiment of the air conditioning control method of the present invention. Further, based on a first embodiment of the air conditioning control method of the present invention, a second embodiment of the air conditioning control method of the present invention is proposed. In this embodiment, after step S30, the air conditioning control method further includes:

[0077] Step S40: Calculate the first duration for which the first difference is greater than or equal to the current dew point temperature difference, and determine whether the first duration is greater than or equal to a preset first duration threshold.

[0078] Step S41: If the first duration is greater than or equal to a preset first duration threshold, then the dehumidification mode is activated to dehumidify the room.

[0079] In this embodiment, the duration of this state, i.e., the first duration, is recorded when the first difference between the indoor temperature and the door / window temperature is greater than or equal to the current dew point temperature difference. The preset first duration threshold can be set according to actual needs. When the first duration is greater than or equal to the first duration threshold, it not only indicates that the time the doors and windows have been open has reached a certain limit, but also that the prolonged opening of the doors and windows leads to a significant risk of condensation indoors. At this point, simply reducing fresh air intake and increasing exhaust air intake is unlikely to avoid the risk of condensation. Therefore, if the first duration is greater than or equal to the preset first duration threshold, the dehumidification mode of the air conditioning system needs to be activated to efficiently dehumidify the indoor environment, thereby further avoiding or delaying the occurrence of indoor condensation.

[0080] In one embodiment, after the step of determining whether the first duration is greater than or equal to a preset first duration threshold, the method further includes:

[0081] Step f: If the first duration is greater than or equal to a preset first duration threshold, then output a warning message about the risk of indoor condensation.

[0082] If the first duration is greater than or equal to the preset first duration threshold, not only should the fresh air mode of the air conditioning system be turned on, but the user should also be reminded. This can be done through methods such as voice broadcasting or flashing lights, as mentioned above, to remind the user of the risk of condensation indoors. This will urge the user to close the doors and windows in time to completely avoid condensation, thereby avoiding waste of electricity and accelerated damage to the air conditioning system.

[0083] In another embodiment, after the step of determining whether the first duration is greater than or equal to a preset first duration threshold, the air conditioning control method further includes:

[0084] Step g: If the first duration is less than a preset first duration threshold, then output a prompt message indicating that the doors and windows are closed.

[0085] Specifically, if the first duration is less than the preset first duration threshold, it means that the doors and windows have been closed by the user. The user can then be reminded that the air conditioning system is operating normally and there is no need to worry about risks such as condensation.

[0086] Through the second embodiment described above, in order to avoid the risk of indoor condensation caused by prolonged opening of doors and windows, the air conditioning system compares the duration of conditions that may cause condensation risk (first duration) with the corresponding duration threshold. After determining that the doors and windows have been open for a long time, it automatically activates the dehumidification mode to quickly dehumidify the room and urges the user to close the doors and windows in time, thereby mitigating or avoiding the occurrence of risks such as indoor condensation and ensuring the comfort of the indoor environment.

[0087] Please refer to Figure 4 , Figure 4 This is a flowchart illustrating a third embodiment of the air conditioning control method of the present invention. Further, based on the above embodiments of the air conditioning control method of the present invention, a third embodiment of the air conditioning control method of the present invention is proposed. In this embodiment, after step S41, the air conditioning control method further includes:

[0088] Step S42: Monitor indoor humidity in real time and calculate the second duration during which the indoor humidity is greater than or equal to a preset humidity threshold.

[0089] Step S43: Determine whether the second duration is greater than or equal to a preset second duration threshold;

[0090] Step S44: If the second duration is greater than or equal to a preset second duration threshold, an alarm is issued and operation stops.

[0091] In this embodiment, indoor humidity can be monitored in real time by installing humidity sensors at a preset distance from the online controller. When the indoor humidity is detected to be greater than or equal to a preset humidity threshold, the duration of this condition is recorded, i.e., the second duration. It is further determined whether this duration exceeds or reaches the second duration threshold. This second duration threshold can be set according to actual needs; it can be equal to or different from the first duration threshold, and the two are not necessarily related. If the second duration is greater than or equal to the second duration threshold, it indicates that even though the air conditioning system has activated dehumidification mode after the doors and windows are opened, it has not prevented indoor condensation, leading to increasingly severe indoor humidity. Continuing dehumidification is therefore ineffective, and since condensation is becoming increasingly severe, and it can be determined that the user is not indoors, an alarm needs to be issued to the user and the air conditioning system should be stopped. This reduces damage to the air conditioner and prevents the waste of electricity when the air conditioning system is not in use.

[0092] In one embodiment, after step S43, the air conditioning control method further includes:

[0093] Step h: If the second duration is less than the preset second duration threshold, then the dehumidification mode is turned off, and the step of statistically determining the first duration when the first difference is greater than or equal to the current dew point temperature difference is executed.

[0094] If the second duration is less than the preset second duration threshold, it means that the indoor humidity has been reduced to a certain limit, indicating that the doors and windows have been closed by the user or the dehumidification mode of the air conditioning system has resisted the risk of condensation caused by opening the doors and windows. Then the dehumidification mode can be turned off to save energy and maintain the comfort of the indoor environment, and then return to step S40 to continue to determine whether there will be a risk of condensation in the future.

[0095] The third embodiment described above enables the determination of whether to turn off the dehumidifier or the entire air conditioning system based on the actual indoor humidity, thereby achieving energy saving and improving the intelligence and economy of the air conditioning system.

[0096] To further understand the present invention and the above embodiments, please refer to Figure 5 , Figure 5 This is a schematic diagram of the overall process of the air conditioning control method of the present invention.

[0097] Where A refers to the second temperature difference threshold, B refers to the first temperature difference threshold, ΔT1 is the first difference, ΔT2 is the second difference, t1 is the first duration, and t2 is the second duration.

[0098] Initially, the system acquires the indoor temperature T1, the door and window temperature T2, and the outdoor ambient temperature T3. It then checks if ΔT2 = |T3 - T1| ≥ A℃. Only if this condition is not met will the system proceed to check if ΔT1 = |T1 - T2| ≥ B℃. This is because if ΔT2 = |T3 - T1| ≥ A℃ is not met, it indicates that the indoor and outdoor temperatures are essentially the same, the air conditioner is not running, or it has only recently started, and the next steps are unnecessary. If T1 = |T1 - T2| ≥ B℃ is not met, it indicates that the door and window temperatures are essentially the same as the indoor temperature, and the doors and windows are closed. If this condition is met, the system prompts the user that the doors and windows are open, and then checks if ΔT1 ≥ dew point temperature difference X℃ is met. If this condition is not met, the air conditioning system continues to operate normally; if this condition is met, the system reduces the fresh air volume and increases the exhaust air volume. Continue to determine whether ΔT1≥X℃ and duration≥t1 are true. If this condition is not true, indicate that the doors and windows are closed. If this condition is true, indicate that there is a risk of condensation indoors, and then activate the dehumidification mode. Determine whether the indoor humidity exceeds the limit and whether the humidity exceeds the limit for more than t2. If this condition is true, the air conditioning system alarms and stops working. If this condition is not true, dehumidification mode is turned off, and then return to the process of determining whether ΔT1≥X℃ and duration≥t1 are true.

[0099] Furthermore, the present invention also provides a computer-readable storage medium. The computer-readable storage medium of the present invention stores an air conditioning control program, wherein, when executed by a processor, the air conditioning control program implements the steps of the air conditioning control method as described above.

[0100] The method implemented when the air conditioning control program is executed can be referred to in various embodiments of the air conditioning control method of the present invention, and will not be repeated here.

Therefore, the present invention can take the form of a completely hardware embodiment, a completely software embodiment, or an embodiment combining software and hardware aspects. Furthermore, the present invention can take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, etc.) containing computer-usable program code.

It will be understood that each block of the flowchart illustrations and / or block diagrams, and combinations of blocks in the flowchart illustrations and / or block diagrams, can be implemented by computer program instructions.
