Description
本發明係有關於一種控制系統及控制裝置。 The invention relates to a control system and a control device.
在工廠所設置之壓縮機係在工廠耗電力之佔有比例大的設備。因此，強烈要求壓縮機之節能化。在工廠，常將複數台壓縮機並列地連接，再經由是壓力緩衝器之接收器槽，將壓縮空氣供給至生產線。壓縮空氣之使用量係因應於生產活動所造成之消耗量的變化而變動。因此，藉接收器槽使供給壓力變成穩定。又，藉壓縮機調整壓縮空氣之供給量，控制對接收器槽的流量。 The compressor installed in the factory is a device with a large proportion of the power consumption of the factory. Therefore, energy saving of the compressor is strongly demanded. In the factory, several compressors are often connected in parallel, and then the compressed air is supplied to the production line through the receiver tank of the pressure buffer. The amount of compressed air used varies according to changes in consumption caused by production activities. Therefore, the supply pressure is stabilized by the receiver groove. The compressor adjusts the supply of compressed air to control the flow rate to the receiver tank.
在專利文獻1所記載之技術，將至少一台與其他台運轉效率特性相異的複數台壓縮機並列地連接。監視接收器槽之流量及壓力、壓縮機之吸入空氣的溫度、以及壓縮機之運轉狀況，並因應於吸入空氣的溫度來修正壓縮機之運轉效率特性，藉此，組成將能源效率差之壓縮機優先地除外的運轉排程表。 In the technology described in Patent Document 1, at least one compressor is connected in parallel with a plurality of compressors having different operating efficiency characteristics from other compressors. Monitor the flow and pressure of the receiver tank, the temperature of the suction air of the compressor, and the operating condition of the compressor, and modify the operating efficiency characteristics of the compressor according to the temperature of the suction air, thereby forming a compression that reduces the energy efficiency. Schedules except for machine priority.

以壓縮機壓縮空氣時，因熱力學之作用而空氣的溫度上升。此熱加上馬達轉動所造成的發熱。結果，壓縮機本身及其周圍的溫度上升。被加熱之空氣係膨脹，而密度降低。因此，為了壓縮機繼續供給定量的壓縮空氣，需要每單位時間壓縮更多的空氣。因此，在溫度上升之環境下，壓縮機之運轉負載增加。即，在壓縮機之運轉，伴隨壓縮空氣的發熱所造成之能源效率的降低。又，在高溫環境下之運轉係因馬達負載之增大及對油之不良影響，使壓縮機本身之劣化加速。結果，壓縮機之壽命變短，或維修之耗費增大。 When the compressor compresses air, the temperature of the air rises due to the effect of thermodynamics. This heat plus the heat generated by the rotation of the motor. As a result, the temperature of the compressor itself and its surroundings rises. The heated air expands and the density decreases. Therefore, in order for the compressor to continue to supply a fixed amount of compressed air, more air needs to be compressed per unit time. Therefore, under an environment where the temperature rises, the operating load of the compressor increases. That is, during the operation of the compressor, the energy efficiency decreases due to the heat generation of the compressed air. In addition, the operation in a high-temperature environment is due to an increase in the load of the motor and an adverse effect on the oil, which accelerates the deterioration of the compressor itself. As a result, the life of the compressor becomes shorter, or the cost of maintenance increases.
作為壓縮機之熱對策，想到導入水冷機構。可是，在水冷機構之導入，耗費龐大的費用。又，壓縮機之設置自由度降低、或需要確保水冷機構之設置場所及維修水冷機構。在氣冷，可避免這種水冷的問題點。以往，作為藉氣冷之熱對策，採用對被設置壓縮機之房間持續地進行換氣，或冷卻的方法。 As a heat countermeasure for compressors, the introduction of a water-cooled mechanism is considered. However, the introduction of a water-cooling mechanism costs a huge amount of money. In addition, the freedom of installation of the compressor is reduced, or it is necessary to secure the installation place of the water cooling mechanism and maintain the water cooling mechanism. In air cooling, this problem of water cooling can be avoided. Conventionally, as a heat countermeasure against air cooling, a method of continuously ventilating or cooling a room where a compressor is installed has been adopted.
在被設置複數台壓縮機之空間整體，即使實施藉氣冷之熱對策，亦因各個壓縮機之運轉性能、運轉狀況以及設置場所之各種的要因，溫度分布不會均勻。即，發生局部的高溫區域。可是，在習知技術，在壓縮機之運轉控制時，未考慮到這種高溫區域的存在。因此，在高溫環境下亦具有高運轉效率特性的壓縮機係即使位於高溫區域，亦以高的運轉強度持續運轉。結果，高溫區域之溫度更上升，而溫度分布成為越來越不均勻。整體上亦無法達成複數台壓縮機之最佳控制。 In the entire space where a plurality of compressors are installed, even if the heat countermeasures by air cooling are implemented, the temperature distribution will not be uniform due to various factors such as the operating performance, operating conditions, and installation sites of each compressor. That is, a local high-temperature region occurs. However, in the conventional technology, the existence of such a high-temperature region is not considered when controlling the operation of the compressor. Therefore, a compressor system that has high operating efficiency characteristics in a high-temperature environment continues to operate with a high operating intensity even in a high-temperature region. As a result, the temperature in the high temperature region rises further, and the temperature distribution becomes more and more uneven. In general, the optimal control of multiple compressors cannot be achieved.
作為壓縮機之運轉環境，一般推薦40℃以下的環 境。可是，在如亞洲之低緯度地區，高溫多濕之氣候的地區多。近年來，在日本亦在夏季觀測到室外溫度超過35℃的日子。在位於這種地區的工廠，僅利用換氣或冷氣，可能難將運轉環境之溫度維持於40℃以下。尤其，在如上述所示之局部的高溫區域，無法維持所推薦之溫度的可能性高。因此，需要藉壓縮機之運轉控制來降低高溫區域的溫度。可是，在習知技術，反而高溫區域的溫度可能上升。相對地，若只是停止位於高溫區域之壓縮機的運轉，可降低高溫區域的溫度。可是，只是這種，無法維持僅滿足需要之壓縮空氣的供給量。 As the operating environment of the compressor, an environment below 40 ° C is generally recommended. However, in low latitudes such as Asia, there are many regions with high temperature and humidity. In recent years, Japan has also observed days with outdoor temperatures exceeding 35 ° C in summer. In factories located in such areas, it may be difficult to maintain the temperature of the operating environment below 40 ° C using only ventilation or cooling. In particular, there is a high possibility that the recommended temperature cannot be maintained in the local high-temperature region as described above. Therefore, it is necessary to reduce the temperature in the high-temperature region by controlling the operation of the compressor. However, in the conventional technology, the temperature in the high-temperature region may rise instead. In contrast, if the operation of the compressor located only in the high temperature region is stopped, the temperature in the high temperature region can be reduced. However, this is the only way to maintain a supply of compressed air that only meets the needs.
本發明之目的在於藉壓縮機的運轉，一面維持僅滿足需要之壓縮空氣的供給量，一面降低在被設置複數台壓縮機之空間內所產生之高溫區域的溫度。 An object of the present invention is to reduce the temperature of a high-temperature region generated in a space where a plurality of compressors are installed while maintaining the supply of compressed air that only satisfies the needs by operating the compressor.
本發明之一形態的控制系統包括：複數台壓縮機，係被設置於室內，壓縮氣體並排出；供給機構，係向共同之供給對象供給從該複數台壓縮機所排出的氣體；測機構，係偵測該室內之溫度分布；以及控制裝置，係從藉該偵測機構所偵測的溫度分布，將在該室內溫度高的區域及溫度低的區域分別特定成高溫點及低溫點，再對該複數台壓縮機，進行一面將從該供給機構所供給之氣體的壓力維持於設定範圍內，一面降低在該高溫點所設置之壓縮機的運轉強度，並提高在該低溫點所設置之壓縮機的運轉強度之控制。 A control system according to one aspect of the present invention includes: a plurality of compressors installed in a room to compress and discharge gas; a supply mechanism for supplying a common supply target with the gas discharged from the plurality of compressors; a measurement mechanism, It detects the temperature distribution in the room; and the control device uses the temperature distribution detected by the detection mechanism to identify the high temperature area and the low temperature area in the room as high temperature points and low temperature points respectively, and then With respect to the plurality of compressors, while maintaining the pressure of the gas supplied from the supply mechanism within a set range, the operation intensity of the compressor provided at the high temperature point is reduced, and the compressor provided at the low temperature point is increased. Control of the operating intensity of the compressor.
在本發明，作為壓縮機之運轉控制，進行一面將從供給機構所供給之氣體的壓力維持於設定範圍內，一面降低在高溫點所設置之壓縮機的運轉強度，並提高在低溫點所設置之壓縮機的運轉強度之控制。因此，可一面維持僅滿足需要之壓縮空氣的供給量，一面降低在被設置複數台壓縮機的空間內所產生之高溫區域的溫度。 In the present invention, as the operation control of the compressor, while maintaining the pressure of the gas supplied from the supply mechanism within a set range, the operation intensity of the compressor installed at a high temperature point is reduced, and the installation at a low temperature point is increased.

Therefore, it is possible to reduce the temperature of the high-temperature region generated in the space where a plurality of compressors are installed while maintaining the supply of compressed air that only satisfies the needs.

參照第4圖，說明本實施形態之控制系統100的動作。尤其，控制裝置101的動作係設置於相當於本實施形態之控制方法。 The operation of the control system 100 according to this embodiment will be described with reference to FIG. 4. In particular, the operation of the control device 101 is provided in a control method corresponding to this embodiment.
在步驟S401，在控制裝置101，輸入設定壓力範圍、設定濕度值以及設定溫度值。設定壓力範圍係自生產線115對接收器槽108所要求之值的設定範圍。設定壓力範圍係在本實施形態根據上下的臨限值所設定，但是亦可僅根據上或下之任一方的臨限值所設定。此外，亦可設定壓力範圍係一個設定值。設定濕度值係由管理者所設定之臨限值。如後述所示，在某區域之濕度超過設定濕度值的情況，位於該區域之壓縮機102的運轉被停止。設定溫度亦是由管理者所設定之臨限值。例如，設定溫度是30℃之值。如後述所示，在某區域之溫度超過設定溫度值的情況，位於該區域之壓縮機102的運轉強度被降低。另一方面，在某區域之溫度低於設定溫度值的情況，位於該區域之壓縮機102的運轉強度被提高。 In step S401, the control device 101 inputs a set pressure range, a set humidity value, and a set temperature value. The set pressure range is a set range of values required from the production line 115 to the receiver groove 108. The setting pressure range is set based on the upper and lower thresholds in this embodiment, but it can also be set based on only one of the upper or lower thresholds. In addition, the pressure range can be set to a set value. The set humidity value is a threshold value set by the administrator. As described later, when the humidity in a certain area exceeds a set humidity value, the operation of the compressor 102 located in the area is stopped. The set temperature is also a threshold value set by the administrator. For example, the set temperature is a value of 30 ° C. As will be described later, when the temperature in a certain area exceeds a set temperature value, the operating intensity of the compressor 102 located in the area is reduced. On the other hand, when the temperature in a certain area is lower than the set temperature value, the operating intensity of the compressor 102 located in the area is increased.
在步驟S402，控制裝置101的控制部312係使複數台壓縮機102的運轉開始。同時，在步驟S414，控制裝置 101之控制部312係使空調機109的運轉開始。在步驟S415，空調機109係使因應於在步驟S401所輸入之設定濕度值及設定溫度的運轉繼續。 In step S402, the control unit 312 of the control device 101 starts the operation of the plurality of compressors 102. At the same time, in step S414, the control unit 312 of the control device 101 starts the operation of the air conditioner 109. In step S415, the air conditioner 109 continues the operation corresponding to the set humidity value and the set temperature input in step S401.
在步驟S403，控制裝置101的控制部312係比較壓力感測器114的測量壓力值、與在步驟S401所輸入之設定壓力範圍的下臨限值。在壓力感測器114之測量壓力值比臨限值低的情況，在步驟S404，控制裝置101的控制部312係提高至少一台壓縮機102的運轉強度。然後，再進行步驟S403的處理。 In step S403, the control unit 312 of the control device 101 compares the measured pressure value of the pressure sensor 114 with the lower threshold value of the set pressure range input in step S401. In a case where the measured pressure value of the pressure sensor 114 is lower than the threshold value, the control unit 312 of the control device 101 increases the operation intensity of at least one compressor 102 in step S404. Then, the process of step S403 is performed again.
在步驟S405，控制裝置101的控制部312係比較壓力感測器114的測量壓力值、與在步驟S401所輸入之設定壓力範圍的上臨限值。在壓力感測器114之測量壓力值比臨限值高的情況，在步驟S406，控制裝置101的控制部312係降低至少一台壓縮機102的運轉強度。然後，再進行步驟S405的處理。 In step S405, the control unit 312 of the control device 101 compares the measured pressure value of the pressure sensor 114 with the upper threshold value of the set pressure range input in step S401. In a case where the measured pressure value of the pressure sensor 114 is higher than the threshold value, the control unit 312 of the control device 101 reduces the operating intensity of at least one compressor 102 in step S406. Then, the process of step S405 is performed again.
在步驟S407，控制裝置101之特定部311係藉由比較溫濕度感測器113之測量溫度值、與在步驟S401所輸入之設定溫度值，抽出高溫點。即，控制裝置101之特定部311係從藉偵測機構104所偵測的溫度分布，將在室內溫度高之區域特定成高溫點。在第5圖所示之例子，C1之運轉環境的溫度高。在此情況，在步驟S408，控制裝置101之控制部312進行降低C1之運轉強度的控制。即，控制裝置101之控制部312進行降低在藉特定部311所特定之高溫點所設置的壓縮機102之運轉強度的控制。 In step S407, the specific part 311 of the control device 101 extracts a high temperature point by comparing the measured temperature value of the temperature and humidity sensor 113 and the set temperature value input in step S401. That is, the specific portion 311 of the control device 101 specifies a high temperature point in a region where the indoor temperature is high from the temperature distribution detected by the detection mechanism 104. In the example shown in Fig. 5, the temperature of the operating environment of C1 is high. In this case, in step S408, the control section 312 of the control device 101 performs control to reduce the operating intensity of C1. That is, the control unit 312 of the control device 101 performs control to reduce the operating intensity of the compressor 102 provided at the high temperature point specified by the specific unit 311.
在步驟S409，控制裝置101之特定部311係藉由比較溫濕度感測器113之測量溫度值、與在步驟S401所輸入之設定溫度值，抽出低溫點。即，控制裝置101之特定部311係從藉偵測機構104所偵測的溫度分布，將在室內溫度低之區域特定成低溫點。在步驟S410，控制裝置101之控制部312進行提高在藉特定部311所特定之低溫點所設置的壓縮機102之運轉強度的控制。 In step S409, the specific part 311 of the control device 101 extracts a low temperature point by comparing the measured temperature value of the temperature and humidity sensor 113 and the set temperature value input in step S401. That is, the specific portion 311 of the control device 101 specifies a low temperature point in a region where the indoor temperature is low from the temperature distribution detected by the detection mechanism 104. In step S410, the control section 312 of the control device 101 performs control to increase the operation intensity of the compressor 102 provided at the low temperature point specified by the specific section 311.
在步驟S411，控制裝置101之特定部311係藉由比較溫濕度感測器113之測量濕度值、與在步驟S401所輸入之設定濕度值，抽出高濕點。即，控制裝置101之特定部311係從藉偵測機構104所偵測的濕度分布，將在室內濕度高之區域特定成高濕點。在第5圖所示之例子，C6之運轉環境的濕度高。在此情況，在步驟S412，控制裝置101之控制部312停止C6之運轉，並藉由關閉連接C6與壓縮空氣配管111之閥110，將C6與壓縮空氣供給系統分離。即，控制裝置101之控制部312進行停止在藉特定部311所特定之高濕點所設置的壓縮機102之運轉的控制。反之，在停止中之壓縮機102的運轉環境的測量濕度值不超過設定濕度值的情況，在步驟S413，控制裝置101之控制部312係使該壓縮機102的運轉開始，並打開連接該壓縮機102與壓縮空氣配管111的閥110。 In step S411, the specific part 311 of the control device 101 extracts a high humidity point by comparing the measured humidity value of the temperature and humidity sensor 113 and the set humidity value input in step S401. That is, the specific portion 311 of the control device 101 specifies a high-humidity point in an area with high indoor humidity from the humidity distribution detected by the detection mechanism 104. In the example shown in Figure 5, the humidity of the C6 operating environment is high. In this case, in step S412, the control section 312 of the control device 101 stops the operation of C6, and closes the valve 110 connecting the C6 and the compressed air piping 111 to separate the C6 from the compressed air supply system. That is, the control unit 312 of the control device 101 performs control to stop the operation of the compressor 102 provided at the high-humidity point specified by the specific unit 311. Conversely, when the measured humidity value of the operating environment of the compressor 102 during the stop does not exceed the set humidity value, in step S413, the control unit 312 of the control device 101 starts the operation of the compressor 102 and opens the connection to the compressor Machine 102 and valve 110 of the compressed air piping 111.
在步驟S412及步驟S413的處理之後，再進行步驟S403以後的處理。此外，在步驟S404，提高將藉正前之步驟S408的處理被降低運轉強度的壓縮機102、與藉正前之步驟S412的處理被停止運轉的壓縮機102除外之至少一台之壓 縮機102的運轉強度。又，在步驟S406，降低將藉正前之步驟S410的處理被提高運轉強度的壓縮機102、與藉正前之步驟S412的處理被停止運轉的壓縮機102除外之至少一台之壓縮機102的運轉強度。 After the processes in steps S412 and S413, the processes in and after step S403 are performed. In addition, at step S404, at least one compressor 102 is increased except the compressor 102 whose operation intensity is reduced by the processing of step S408 before the borrowing, and the compressor 102 whose operation is stopped by the processing of step S412 is borrowed Operating intensity. In step S406, at least one compressor 102 except for the compressor 102 whose operation intensity is increased by the processing of step S410 before the borrowing and the compressor 102 whose operation is stopped by the processing of step S412 before the borrowing is reduced. Operating intensity.
如上述所示，在從步驟S403至步驟S410，控制裝置101之控制部312係對複數台壓縮機102，進行一面將從供給機構103所供給之氣體的壓力維持於設定範圍內，一面降低在高溫點所設置之壓縮機102的運轉強度，並提高在低溫點所設置之壓縮機102的運轉強度之控制。關於調整各壓縮機102之運轉強度的程度，係使用任意的方法，以最佳化。例如，進行藉機械學習的最佳化。 As described above, from step S403 to step S410, the control unit 312 of the control device 101 performs a reduction on the plurality of compressors 102 while maintaining the pressure of the gas supplied from the supply mechanism 103 within a set range. Control of the operating intensity of the compressor 102 set at a high temperature point and improving the operating intensity of the compressor 102 set at a low temperature point. Regarding the degree of adjustment of the operating intensity of each compressor 102, an arbitrary method is used for optimization. For example, optimization by borrowing machine learning.
如上述所示，在從步驟S403至步驟S413，控制裝置101之控制部312係對複數台壓縮機102，進行一面將從供給機構103所供給之氣體的壓力維持於設定範圍內，一面停止在高濕點所設置之壓縮機102的運轉。在此控制，包含因應於需要，提高其他的壓縮機102之運轉強度的控制，以免從供給機構103所供給之氣體的壓力比設定範圍更低。 As described above, from step S403 to step S413, the control unit 312 of the control device 101 controls the plurality of compressors 102 while maintaining the pressure of the gas supplied from the supply mechanism 103 within a set range, and stops at The operation of the compressor 102 provided at the high humidity point. Here, the control includes a control for increasing the operation intensity of the other compressors 102 as necessary to prevent the pressure of the gas supplied from the supply mechanism 103 from being lower than the set range.
在本實施形態，作為壓縮機102之運轉控制，進行一面將從供給機構103所供給之氣體的壓力維持於設定範圍內，一面降低在高溫點所設置之壓縮機102的運轉強度，並提高在低溫點所設置之壓縮機102的運轉強度之控制。因此，可一面維持僅滿足需要之壓縮空氣的供給量，一面降低在被設置複數台壓縮機102的空間內所產生之高溫區域的溫度。 In this embodiment, as the operation control of the compressor 102, while maintaining the pressure of the gas supplied from the supply mechanism 103 within a set range, the operation intensity of the compressor 102 installed at a high temperature point is reduced, and the pressure Control of the operating intensity of the compressor 102 set at a low temperature point. Therefore, the temperature of the high-temperature region generated in the space in which the plurality of compressors 102 are installed can be reduced while maintaining the supply of compressed air that only meets the requirements.
在本實施形態，在溫濕度受到管理之環境下設置複數個溫濕度感測器113與複數台壓縮機102。控制裝置101係根據各種感測器之值，個別地控制壓縮機102的運轉強度，藉此，消除溫度之不均勻分布。結果，可維持壓縮運轉效率佳的環境。因此，可得到節能化、長壽命化、維修費用之降低之各種的效果。 In this embodiment, a plurality of temperature and humidity sensors 113 and a plurality of compressors 102 are provided in an environment where temperature and humidity are managed. The control device 101 individually controls the operation intensity of the compressor 102 according to the values of various sensors, thereby eliminating uneven temperature distribution. As a result, an environment with high compression operation efficiency can be maintained. Therefore, various effects such as energy saving, longer life, and reduction in maintenance costs can be obtained.
在本實施形態，在壓縮機室或工廠的某空間之被設置複數台壓縮機102的場所，導入具有冷氣性能的空調機109。藉冷風發揮壓縮機102及其周邊環境之氣冷效果。在空調機109的運轉，需要投入能量。可是，藉空調機109之導入，尤其在高溫多濕的氣候條件，可期待壓縮機102之節能化、劣化防止、維修頻率之降低。 In the present embodiment, an air conditioner 109 having air-conditioning performance is introduced in a place where a plurality of compressors 102 are installed in a compressor room or a certain space of a factory. The air cooling effect of the compressor 102 and its surrounding environment is exerted by cold wind. Energy is required to operate the air conditioner 109. However, with the introduction of the air conditioner 109, especially in high-temperature and humid climate conditions, the energy saving of the compressor 102, the prevention of deterioration, and the reduction of the maintenance frequency can be expected.
由於各個壓縮機102之設置場所、性能、運轉狀況、或者對其他的熱源之距離的各種的要因，即使位於被設置空調機109的環境之下，各個壓縮機102附近或各個壓縮機102本身的溫度係不會相同。具體而言，即使藉冷氣運轉而空調機109附近的溫度變成充分低，亦因溫度之不均勻分布而處在高溫環境下的壓縮機102，係無法享受冷卻的恩惠。反之，在尤其因接近發熱量大之壓縮機102的理由而空調機109的周邊係比其他的場所高溫的情況，空調機109成為在冷卻超出需要地消耗能量。結果，無法得到充分之節能效果。對這種問題，在本實施形態，導入運轉負載可調的壓縮機102。藉由監視各壓縮機102附近的空間溫度或各壓縮機102本身的溫度，降低位於溫度比較高的環境之壓縮機102的運轉強度，並提高位於溫 度比較低的環境之壓縮機102的運轉強度。因此，可降低高溫點之溫度，並提高低溫點之溫度。因此，可消除空間溫度之不均勻分布。 Due to various factors such as the installation location, performance, operating conditions, or distance to other heat sources of each compressor 102, even under the environment where the air conditioner 109 is installed, the vicinity of each compressor 102 or each compressor 102 itself The temperature system will not be the same. Specifically, even if the temperature in the vicinity of the air conditioner 109 becomes sufficiently low by the operation of the air conditioner, the compressor 102 which is in a high temperature environment due to the uneven distribution of the temperature cannot enjoy the benefit of cooling. On the other hand, when the surroundings of the air conditioner 109 are higher than other places due to the proximity to the compressor 102 having a large amount of heat, the air conditioner 109 consumes energy more than necessary for cooling. As a result, a sufficient energy saving effect cannot be obtained. In response to such a problem, in the present embodiment, a compressor 102 with an adjustable operating load is introduced. By monitoring the temperature of the space near each compressor 102 or the temperature of each compressor 102 itself, the operating intensity of the compressor 102 located in a relatively high temperature environment is reduced, and the operating intensity of the compressor 102 located in a relatively low temperature environment is increased. . Therefore, the temperature at the high temperature point can be reduced, and the temperature at the low temperature point can be increased. Therefore, the uneven distribution of the space temperature can be eliminated.
藉空調機109所供給之冷卻空氣亦是低濕度空氣。因此，可應付溫度及濕度之雙方的問題。可是，在被供給水蒸氣的環境及被供給多濕之外氣的位置，壓縮機102所吸入之空氣的濕度成為問題。在壓縮機102之吸入空氣含有很多濕氣的情況，在壓縮過程空氣中之大量的水分凝結，並被儲存於壓縮機102的內部。因此，壓縮效率降低，而運轉強度之維持變成困難，或能量消耗量增大。對這種問題，在本實施形態，使用溫濕度感測器113來監視濕度，並特定成為多濕的場所。而且，所特定之場所的壓縮機102被停止。因此，可避免濕度的問題。因應於濕度之壓縮機102的停止係對空間的溫度分布有影響。可是，利用其他的壓縮機102之運轉控制的最佳化，維持本實施形態之效果。 The cooling air supplied by the air conditioner 109 is also low-humidity air. Therefore, it is possible to cope with the problems of both temperature and humidity. However, the humidity of the air sucked in by the compressor 102 becomes a problem in the environment where water vapor is supplied and the location where high humidity is supplied. In the case where the intake air of the compressor 102 contains a lot of moisture, a large amount of moisture in the air during the compression process is condensed and stored inside the compressor 102. As a result, the compression efficiency is reduced, it becomes difficult to maintain the operating strength, or the energy consumption is increased. In response to this problem, in the present embodiment, the temperature and humidity sensor 113 is used to monitor the humidity, and it is specified as a humid place. Then, the compressor 102 at the specific place is stopped. Therefore, the problem of humidity can be avoided. The stop of the compressor 102 according to the humidity has an influence on the temperature distribution in the space. However, the effects of this embodiment are maintained by optimizing the operation control of the other compressors 102.
若依據本實施形態，藉以往係未考慮到之壓縮機102之運轉強度的控制、及因應於濕度之壓縮機102的停止，可實現適合壓縮機102之運轉的環境。即，在本實施形態，作為管理室內環境之控制系統100所使用的參數，在控制裝置101，輸入接收器槽108，以及各壓縮機102或其附近之溫度及濕度，並進行壓縮機102之最佳的個別運轉控制。因此，可得到在習知方法所無法達成的節能效果。 According to this embodiment, an environment suitable for the operation of the compressor 102 can be realized by controlling the operation intensity of the compressor 102 which has not been considered in the past and stopping the compressor 102 due to humidity. That is, in this embodiment, as the parameters used by the control system 100 for managing the indoor environment, the temperature and humidity of the compressor 102, the receiver tank 108, and each compressor 102 or the vicinity thereof are input to the control device 101, Optimal individual operation control. Therefore, energy saving effects that cannot be achieved by the conventional method can be obtained.

關於從步驟S802至步驟S813的處理，因為係與 第4圖之從步驟S402至步驟S413的處理相同，所以省略說明。 The processing from step S802 to step S813 is the same as the processing from step S402 to step S413 in FIG. 4, and therefore description thereof is omitted.
在步驟S801，在控制裝置101，除了設定壓力範圍、設定濕度值以及設定溫度值以外，還輸入設定溫度範圍。設定溫度範圍係可變更空調機109之設定溫度的範圍，由管理者所設定。設定溫度範圍係在本實施形態根據上下之臨限值所設定，但是亦可僅根據上或下之任一方的臨限值所設定。 In step S801, the control device 101 inputs a set temperature range in addition to the set pressure range, the set humidity value, and the set temperature value. The set temperature range is a range in which the set temperature of the air conditioner 109 can be changed, and is set by an administrator. The set temperature range is set based on the upper and lower thresholds in this embodiment, but it can also be set based on either the upper or lower thresholds.
與步驟S802同時，在步驟S814，控制裝置101之控制部312使空調機109的運轉開始。在步驟S815，控制裝置101的分析部313係經由信號線112，從各個壓縮機102及空調機109接收耗電量之資料。控制裝置101的分析部313係使用所接收之資料，決定壓縮機102及空調機109之耗電量成為最小之空調機109的設定溫度。 Simultaneously with step S802, in step S814, the control unit 312 of the control device 101 starts the operation of the air conditioner 109. In step S815, the analysis unit 313 of the control device 101 receives data on power consumption from each of the compressor 102 and the air conditioner 109 via the signal line 112. The analysis unit 313 of the control device 101 determines the set temperature of the air conditioner 109 that minimizes the power consumption of the compressor 102 and the air conditioner 109 using the received data.
此處，在第8圖，表示複數台壓縮機102之耗電量、空調機109之耗電量以及空調機109之設定溫度的關係。縱軸係耗電量。橫軸係空調機109的設定溫度。橫軸係從左往右逐漸地變成低溫。在第8圖之圖形，畫壓縮機102之耗電量及空調機109之耗電量。此外，為了簡化說明，關於壓縮機102之耗電量，表示一條曲線，但是實際上因應於壓縮機102之設置台數之條數的曲線存在。空調機109之設定溫度降低時，空調機109的耗電量係以直線或曲線單調增加。另一方面，壓縮機102之耗電量係因既述之理由而單調減少。在第8圖，空調機109之設定溫度為X℃時，空調機109之耗電量Wa與壓縮機102之耗電量Wc的和成為最小值Wt。因此，得知在此時間點之空調機109之設定溫度的最佳值是X℃。被供給至生產線 115之壓縮空氣量係根據生產活動而變化。壓縮機102之設置場所的溫濕度環境亦根據外在要因及與第1實施形態相同之溫度分布的均勻化而變化。因此，X℃係只不過是在某時間點之最佳解。控制裝置101的分析部313係依此方式適當地求得時時刻刻地變化之最佳解。即，控制裝置101之分析部313係根據藉偵測機構104所偵測之複數台壓縮機102的耗電量、藉偵測機構104所偵測之空調機109的耗電量、以及空調機109的設定溫度，分析藉由降低空調機109的設定溫度所得之複數台壓縮機之耗電量的減少量、與藉由提高空調機的設定溫度所得之空調機之耗電量的減少量。 Here, Fig. 8 shows the relationship between the power consumption of the plurality of compressors 102, the power consumption of the air conditioner 109, and the set temperature of the air conditioner 109. The vertical axis system consumes electricity. The set temperature of the horizontal axis air conditioner 109. The horizontal axis system gradually becomes low temperature from left to right. In the graph of FIG. 8, the power consumption of the compressor 102 and the power consumption of the air conditioner 109 are drawn. In addition, in order to simplify the description, a curve is shown regarding the power consumption of the compressor 102, but in fact, a curve corresponding to the number of the compressors 102 is provided. When the set temperature of the air conditioner 109 decreases, the power consumption of the air conditioner 109 monotonously increases in a straight line or a curve. On the other hand, the power consumption of the compressor 102 decreases monotonously for the reasons described above. In FIG. 8, when the set temperature of the air conditioner 109 is X ° C., the sum of the power consumption Wa of the air conditioner 109 and the power consumption Wc of the compressor 102 becomes the minimum value Wt. Therefore, it is known that the optimum value of the set temperature of the air conditioner 109 at this time point is X ° C. The amount of compressed air supplied to the production line 115 varies according to production activities. The temperature and humidity environment of the place where the compressor 102 is installed also changes depending on external factors and the uniformity of the temperature distribution similar to the first embodiment. Therefore, X ℃ is just the best solution at a certain point in time. The analysis section 313 of the control device 101 appropriately obtains an optimal solution that changes from moment to moment in this manner. That is, the analysis unit 313 of the control device 101 is based on the power consumption of the plurality of compressors 102 detected by the detection mechanism 104, the power consumption of the air conditioner 109 detected by the detection mechanism 104, and the air conditioner. The set temperature of 109 analyzes the reduction in power consumption of a plurality of compressors obtained by reducing the set temperature of the air conditioner 109 and the reduction in power consumption of the air conditioner obtained by increasing the set temperature of the air conditioner.
在步驟S816，控制裝置101之控制部312係因應於在步驟S815所求得之最佳值，在步驟S401所輸入之設定溫度範圍內變更空調機109的設定溫度。即，控制裝置101之控制部312係因應於分析部313的之分析結果，調整空調機109的設定溫度。在步驟S817，空調機109係進行因應於在步驟S801所輸入之設定濕度值及設定溫度範圍、與在步驟S816之變更後之設定溫度的運轉。然後，再進行步驟S815的處理。 In step S816, the control unit 312 of the control device 101 changes the set temperature of the air conditioner 109 within the set temperature range input in step S401 in accordance with the optimal value obtained in step S815. That is, the control unit 312 of the control device 101 adjusts the set temperature of the air conditioner 109 in accordance with the analysis result of the analysis unit 313. In step S817, the air conditioner 109 performs an operation corresponding to the set humidity value and the set temperature range input in step S801 and the set temperature after the change in step S816. Then, the process of step S815 is performed again.
在本實施形態，進行時時刻刻地變化之壓縮機102的運轉條件及因應於溫度條件之空調機109之溫度設定的自動化，而可使空調機109及壓縮機102的總耗電量變成最小。 In this embodiment, the operating conditions of the compressor 102 that are constantly changing and the temperature setting of the air conditioner 109 according to the temperature conditions are automated, so that the total power consumption of the air conditioner 109 and the compressor 102 can be minimized. .
在本實施形態，作為管理室內環境之控制系統100所使用的參數，在控制裝置101，輸入各壓縮機102之耗電力、與空調機109之耗電力，進行空調機109的運轉控制。因此， 可得到在習知方法所無法達成的節能效果。 In this embodiment, as a parameter used by the control system 100 for managing the indoor environment, the control device 101 inputs the power consumption of each compressor 102 and the power consumption of the air conditioner 109 to control the operation of the air conditioner 109. Therefore, energy saving effects that cannot be achieved by the conventional method can be obtained.
在本實施形態，係與第1實施形態一樣，藉軟體實現特定部311、控制部312以及分析部313的功能，但是與第1實施形態一樣，亦可藉軟體與硬體的組合實現特定部311、控制部312以及分析部313的功能。 In this embodiment, the functions of the specific unit 311, the control unit 312, and the analysis unit 313 are implemented by software in the same way as in the first embodiment. However, similar to the first embodiment, the specific unit can also be implemented by a combination of software and hardware. Functions of 311, control section 312, and analysis section 313.
