現有的冷氣機,在運作時乃是由使用者手持遙控器對冷氣機進行遙控來令其依想要的設定溫度進行運作,而現有的冷氣機也會依據使用者所設定的溫度來進行運作,利用其本身所具有的溫度感測器來判斷目前的室溫與使用者的設定溫度是否有所差距,並藉由溫度的差距大或小來決定以高出力或低出力模式運轉。亦即,在室內溫度高於設定溫度2℃以上時,即以高出力模式運轉,差距在2℃以內時,則以中出力模式運轉,差距在1℃以內時,則以低出力模式運轉。藉以達到目前俗稱的恆溫空調的效果。The existing air conditioner is operated by a user holding a remote control to remotely control the air conditioner to make it operate at a desired set temperature, and the existing air conditioner also operates according to the temperature set by the user. , Use its own temperature sensor to determine whether the current room temperature is different from the user's set temperature, and decide whether to operate in high or low output mode based on the difference in temperature.

Such technology is rough in judging the temperature and operation mode, although it can operate at high output when demand is high, and When the demand is low, it operates at a low output to achieve a certain degree of energy saving effect, but it cannot provide a more detailed energy saving effect according to the current indoor temperature trend.

The obtained current room temperature is used to determine the trend of the room temperature during this time; C) Temperature judgment: the microcomputer determines the current room temperature Whether the temperature is higher than the target temperature by more than a predetermined value, if yes, then proceed to the next step; if not, the controller instructs the air conditioner to operate in the lowest energy consumption mode, and returns to step B); D ) Trend judgment: With the change trend of room temperature, the microcomputer judges whether the current room temperature is showing a decreasing trend, that is, whether the plural current room temperature is lower than the later temperature. The lower the degree, if it is, the controller instructs the air conditioner to use the target temperature as the set temperature for its operation, and instructs the air conditioner to operate in the standard mode, and returns to step B), if not, proceed to the next One step; and E) high output mode: the controller commands the air conditioner to operate in high output mode, and returns to step B).
由上述步驟可知,本發明乃是藉由目前室內溫度的變化趨勢,藉以決定冷氣機的運轉模式,進而達到更為節能的效果。It can be known from the above steps that the present invention determines the operation mode of the air conditioner by using the current indoor temperature change trend, thereby achieving a more energy-saving effect.
本發明之再一目的乃在於提供一種冷氣機的節能控制方法,其可由遙控器來進行冷氣機運作模式的判斷,進而遙控冷氣機依其判斷的運作模式來運作。Another object of the present invention is to provide an energy-saving control method for an air conditioner, which can determine the operation mode of the air conditioner by a remote controller, and further the remote air conditioner operates according to the operation mode determined by the remote control.
其主要是使前述方法中的控制器以冷氣機的遙控器來取代,該遙控器係以紅外線訊號遙控該冷氣機。The main method is to replace the controller in the foregoing method with a remote controller of an air conditioner, which uses an infrared signal to remotely control the air conditioner.

Operation, and then achieved a more energy-saving effect.
為了詳細說明本發明之技術特點所在,茲舉以下之較佳實施例並配合圖式說明如後,其中:In order to explain the technical features of the present invention in detail, the following preferred embodiments are described in conjunction with the drawings as follows, wherein:
如第1圖至第3圖所示,本發明第一較佳實施例所提供之一種冷氣機的節能控制方法,主要具有下列步驟:As shown in FIG. 1 to FIG. 3, an energy-saving control method for an air conditioner provided by the first preferred embodiment of the present invention mainly includes the following steps:
A) 開啟冷氣機:如第2圖所示,以一控制器11開啟一冷氣機21使其以運作,其中,該控制器11係預設一目標溫度TT,且該控制器11具有一微電腦12,該冷氣機21的運作模式至少有三種:最低耗能模式、標準模式以及高出力模式,有些冷氣機可能不是以模式種類來分類其運作方式,例如多段式變頻冷氣可以藉由壓縮機運轉速率以及風扇運轉速率來變化,這些功能的調整上,一樣可以產生最低耗能模式、高出力模式、標準模式以及其他模式,這樣的架構仍為本案技術概念所涵蓋。該控制器11於本第一實施例中係為冷氣機的遙控器,該遙控器係以紅外線訊號來遙控該冷氣機21。A) Turn on the air conditioner: As shown in FIG. 2, a controller 11 is used to turn on an air conditioner 21 for operation. The controller 11 presets a target temperature TT, and the controller 11 has a microcomputer. 12. There are at least three operating modes of the air conditioner 21: minimum energy consumption mode, standard mode and high output mode. Some air conditioners may not be classified by the type of operation. For example, multi-stage variable frequency air conditioners can be operated by compressors. The speed and the running speed of the fan vary. The adjustment of these functions can also produce the lowest energy consumption mode, high output mode, standard mode and other modes. Such an architecture is still covered by the technical concept of this case. The controller 11 is a remote controller of the air conditioner in the first embodiment. The remote controller is an infrared signal to remotely control the air conditioner 21.
B) 取得室溫變化趨勢:如第3圖所示,該微電腦12藉由一溫度感測器14每隔一預定時間取得一次目前室溫,總共取得六次的目前室溫CT,藉由取得的該複數目前室溫CT來判斷在這段時間內的室溫變化趨勢。於本實施例中,前述的預定時間以10-20秒為適合,而以15秒為例,而該溫度感測器14可以是設置於該控制器11上的,也可以是設於外部而以有線或無線方式電性連接於該微電腦12的,設於外部的方式由於乃習知技術,因此容不以圖式表示。而實際上取得的室溫值,可以準確到小數點以下一位數。實質上,目前室溫CT取得的樣本數量愈多,則判斷愈容易準確,但取得太多次的目前室溫CT,會拖慢判斷的時間,因此,在每15秒取樣一次的情況下,雖然3次以上即可看出趨勢,但仍以取得5-6次的目前室溫CT來判斷室溫變化趨勢為最適合。B) Obtaining the trend of room temperature: As shown in FIG. 3, the microcomputer 12 obtains the current room temperature at a predetermined time by a temperature sensor 14 and obtains a total of six current room temperature CTs. The complex current room temperature CT is used to judge the room temperature change trend during this period. In this embodiment, the aforementioned predetermined time is suitable for 10-20 seconds, and 15 seconds is taken as an example. The temperature sensor 14 may be provided on the controller 11 or externally. The externally connected device that is electrically connected to the microcomputer 12 in a wired or wireless manner is known in the art, and therefore cannot be represented in a diagram. In fact, the room temperature value obtained can be accurate to one digit below the decimal point. In essence, the larger the number of samples obtained from the current room temperature CT, the easier and more accurate the judgment will be. However, obtaining too many current room temperature CTs will slow down the judgment time. Therefore, in the case of sampling every 15 seconds, Although the trend can be seen more than 3 times, it is still most suitable to determine the trend of room temperature by obtaining the current room temperature CT 5-6 times.
C) 溫度判斷:該微電腦12判斷該複數目前室溫CT是否都高於該目標溫度TT在一預定數值以上,若”是”,則接著進行下一步驟,若”否”,則該微電腦12即會藉由該控制器11發出遙控訊號命令該冷氣機21以最低耗能模式運轉,並回到步驟B),因此,這個控制器11在實際使用時,若使用遙控信號來命令該冷氣機21,則以保持該控制器11對著該冷氣機21的方式置放較為合適。前述的最低耗能模式,是指風量最低且該冷氣機21內的壓縮機持續運轉,或風量最低且壓縮機以最低速率運轉,或風量最低的送風模式。此外,於本實施例中,前述的預定數值,係以0.5-1℃(攝氏溫度)為適當,而以0.5℃為例。前述的”否”的狀況中,無論該複數目前室溫CT是有部份低於該目標溫度TT,或是全部都低於該目標溫度TT,這都是指目前的室溫已經是很接近或低於該目標溫度TT,不需要再降溫,因此就使該冷氣機21以最低耗能模式運轉。C) Temperature judgment: The microcomputer 12 judges whether the plurality of current room temperature CTs are all higher than the target temperature TT by a predetermined value or more. If "Yes", then proceed to the next step; if "No", the microcomputer 12 That is, the controller 11 sends a remote control signal to instruct the air conditioner 21 to operate in the lowest energy consumption mode, and returns to step B). Therefore, when the controller 11 is in actual use, the remote control signal is used to command the air conditioner. 21, it is more appropriate to keep the controller 11 facing the air conditioner 21. The aforementioned minimum energy consumption mode refers to a supply mode in which the air volume is the lowest and the compressor in the air conditioner 21 is continuously running, or the air volume is the lowest and the compressor is operating at the lowest speed, or the air volume is the lowest. In addition, in this embodiment, the foregoing predetermined value is appropriately 0.5-1 ° C (Celsius temperature), and 0.5 ° C is taken as an example. In the aforementioned "No" condition, whether the current room temperature CT is partially lower than the target temperature TT, or all of them are lower than the target temperature TT, this means that the current room temperature is already close. Or if it is lower than the target temperature TT, no further cooling is required, so the air conditioner 21 is operated in the lowest energy consumption mode.
D) 趨勢判斷:藉由該室溫變化趨勢,該微電腦12判斷目前室溫CT是否呈現降低趨勢,亦即,該複數目前室溫CT是否愈後面的溫度愈低,若”是”,則該微電腦12即會藉由該控制器11發出遙控訊號命令該冷氣機21以該目標溫度TT做為其運轉的設定溫度,且命令該冷氣機21以標準模式運作,並回到步驟B),若”否”,則進行下一步驟,第3圖即顯示室溫變化趨勢是呈現降低趨勢的。此步驟D)中,前述”是”的狀況,乃是由於室溫的趨勢是降低就代表著冷氣機21目前的運作是可以有效降低室溫的,因此就可以不需要進行任何改變,而令冷氣機21持續以其標準模式來運作。而前述”否”的狀況,則代表室溫趨勢不是降低,也就是冷氣機21目前的運作無法降低室溫。D) Trend judgment: Based on the room temperature change trend, the microcomputer 12 judges whether the current room temperature CT is showing a decreasing trend, that is, whether the plural current room temperature CT is lower and the temperature is lower. If "yes", then the The microcomputer 12 then sends a remote control signal through the controller 11 to instruct the air conditioner 21 to use the target temperature TT as the set temperature for its operation, and instructs the air conditioner 21 to operate in the standard mode, and returns to step B). "No", then proceed to the next step. Figure 3 shows that the trend of room temperature is decreasing. In this step D), the above-mentioned "yes" condition is because the tendency of the room temperature to decrease means that the current operation of the air conditioner 21 can effectively reduce the room temperature, and therefore, no change is required, so that The air conditioner 21 continues to operate in its standard mode. The aforementioned “No” condition means that the trend of the room temperature is not reduced, that is, the current operation of the air conditioner 21 cannot reduce the room temperature.
E) 高出力模式:該微電腦12藉由該控制器11發出遙控信號命令該冷氣機21以高出力模式運作,並回到步驟B)。前述的高出力模式,係指風量高且壓縮機持續運轉,或風量最高且壓縮機以最高速率運轉的狀態。在本步驟中,由於室溫是高於目標溫度TT,而且室溫變化趨勢也不是降低的,因此就判斷為需要以更高或最高的運轉能量來提供冷氣效果,因此即以高出力模式進行運轉。E) High output mode: The microcomputer 12 sends a remote control signal through the controller 11 to instruct the air conditioner 21 to operate in high output mode, and returns to step B). The aforementioned high output mode refers to a state where the air volume is high and the compressor is continuously running, or the air volume is the highest and the compressor is operating at the highest speed. In this step, since the room temperature is higher than the target temperature TT, and the trend of room temperature does not decrease, it is judged that it is necessary to provide a cooling effect with a higher or highest operating energy, so it is performed in a high output mode Operational.
藉由上述步驟可知,本發明乃是不斷的由步驟B)至步驟E)之間的迴圈,可以藉由判斷目前室內溫度的變化趨勢,來決定冷氣機21運轉於最低耗能模式、冷氣機本身的自動模式或是高出力模式,進而達到更為節能的效果。此外,本發明乃是藉由遙控器來進行冷氣機21運作模式的判斷,進而遙控冷氣機21依其判斷的運作模式來運作。It can be known from the above steps that the present invention is a continuous loop from step B) to step E), and the air conditioner 21 can be determined to operate in the lowest energy consumption mode and air conditioner by judging the current room temperature change trend. The machine's own automatic mode or high output mode, so as to achieve more energy-saving effects. In addition, the present invention determines the operation mode of the air conditioner 21 by using a remote controller, and further the remote air conditioner 21 operates according to the operation mode determined by the remote control.
請再參閱第4圖,本發明第二較佳實施例所提供之一種冷氣機的節能控制方法,主要概同於前揭第一實施例,不同之處在於:Please refer to FIG. 4 again. An energy-saving control method for an air conditioner provided by a second preferred embodiment of the present invention is mainly similar to the first embodiment disclosed above, except that:
在步驟D)中,在室溫變化趨勢是降低趨勢的條件下,該室溫變化趨勢中之各該相鄰的目前室溫CT之間的差距若是愈來愈小,則代表該室溫變化趨勢是趨向緩和,該微電腦12係減少該預定數值大小於一預定比例,例如,該預定數值原來是1℃,則減少至原來的80%而成為0.8℃。而該室溫變化趨勢中之各該相鄰的目前室溫CT之間的差距若是愈來愈大,則代表該室溫變化趨勢是趨向劇烈,該微電腦12係增加該預定數值大小於一預定比例,例如,該預定數值原來是1℃,則增加至原來的120%而成為1.2℃。In step D), under the condition that the room temperature change trend is a decreasing trend, if the gap between the adjacent current room temperature CTs in the room temperature change trend is getting smaller, it represents the room temperature change. The trend is to ease. The microcomputer 12 reduces the size of the predetermined value to a predetermined ratio. For example, if the predetermined value is originally 1 ° C, it is reduced to 80% and becomes 0.8 ° C. If the gap between the adjacent current room temperature CTs in the room temperature change trend is getting larger, it means that the room temperature change trend is becoming more severe. The microcomputer 12 increases the predetermined value to a predetermined value. For example, if the predetermined value is 1 ° C, the ratio is increased to 120% and becomes 1.2 ° C.
前述的技術,可以藉由室溫變化趨勢來微調該預定數值,在變化趨勢劇烈時調高該預定數值,藉以使室溫在降低時更容易與該預定數值的差距縮小,可以使得變化劇烈的室溫與該目標溫度TT之間的差距更快的達到該預定數值。例如,室溫變化趨勢劇烈時,代表此時的冷氣機21運轉效果過好而使得室溫的降低速度太快,此時假設該預定數值是0.5℃,則提高該預定數值至0.6℃可以讓室溫與該目標溫度TT的差距更快速的達到該預定數值。進而在步驟C)中即被判斷為”否”而以最低耗能模式運轉,此時即可以達到節能效果。而在前述的室溫變化趨勢是趨向緩和時,即代表此時的冷氣機21的運轉僅會讓室溫緩慢下降,因此判斷目前冷氣機21的運轉模式是最適合的模式,因此調低該預定數值,而使得室溫與該目標溫度TT的差距不要太快速的達到該預定數值,進而可以讓室溫更準確的趨近於該目標溫度TT。The foregoing technology can fine-tune the predetermined value by changing the room temperature trend, and increase the predetermined value when the change trend is severe, so that the gap between the room temperature and the predetermined value is more easily reduced when the room temperature decreases, which can make the change drastic. The difference between the room temperature and the target temperature TT reaches the predetermined value more quickly. For example, when the room temperature changes sharply, it means that the air-conditioner 21 is operating too well at this time to reduce the room temperature too quickly. At this time, if the predetermined value is 0.5 ° C, increasing the predetermined value to 0.6 ° C allows The difference between the room temperature and the target temperature TT reaches the predetermined value more quickly. Furthermore, in step C), it is judged as "No" and operates in the lowest energy consumption mode. At this time, the energy saving effect can be achieved. And when the aforementioned room temperature change trend is tending to ease, that means that the operation of the air-conditioner 21 at this time will only slowly decrease the room temperature. Therefore, it is judged that the current operation mode of the air-conditioner 21 is the most suitable mode, so lower the The predetermined value, so that the difference between the room temperature and the target temperature TT does not reach the predetermined value too quickly, so that the room temperature can more accurately approach the target temperature TT.
本第二實施例的其餘步驟以及所能達成之功效均概同於前揭第一實施例,容不再予贅述。The remaining steps of the second embodiment and the effects that can be achieved are the same as those of the first embodiment disclosed previously, and will not be described again.
請再參閱第5圖,本發明第三較佳實施例所提供之一種冷氣機的節能控制方法,主要概同於前揭第一實施例,不同之處在於:Please refer to FIG. 5 again. An energy-saving control method for an air conditioner provided by a third preferred embodiment of the present invention is mainly similar to the first embodiment disclosed above, except that:
