Description

本発明は、室内空間に設けられた空気調和制御の温度設定および照明装置の調光制御の連動制御システムに関する。  The present invention relates to a temperature setting for air conditioning control provided in an indoor space and a linked control system for dimming control of a lighting device.

従来の空気調和装置や照明制御装置はそれぞれ単独に制御を行っている。空気調和装置では、特開平１０−２７８５３９号公報に記載のように、外気温度に関連付けられた自動設定温度を、室内に在室しているユーザの設定温度変更操作の情報を学習させて修正するもがある。自動設定温度は実施例では外気温度が高いほど低く設定されている。
照明制御装置の場合、日射量が多いときは室内窓際照明器具の調光度を低く（暗く）設定し、日射量が低い場合は高く設定する制御を行っている。
特開平１０−２７８５３９号公報 Conventional air conditioners and lighting control devices each independently control. In the air conditioner, as described in Japanese Patent Application Laid-Open No. 10-278539, the automatic set temperature associated with the outside air temperature is corrected by learning the information of the set temperature changing operation of the user who is in the room. There is also. In the embodiment, the automatic set temperature is set lower as the outside air temperature is higher.

Japanese Patent Laid-Open No. 10-278539

上記の特開平１０−２７８５３９号公報記載の従来技術は、特定ユーザの快適性を実現できるが、スーパーマーケットやコンビニエンスストアなどの不特定多数の快適性については考慮されていない。また設定温度は外気温度が高いほど低く設定されているので消費電力は増加する。
さらに上記従来技術は外気温度が高いほど室内の設定温度を低く設定しているので室内温度と外気温度との温度差が大きくなり、室内空間への出入りをするとき温度が急変して不快に感じることがある。また照明制御においては個別に制御を行っているため、ユーザサイドからより効果的な省電力性と快適性が得られる空調照明連動システムを提供することを目的とする。The conventional technology described in Japanese Patent Laid-Open No. 10-278539 described above can realize the comfort of a specific user, but does not take into account a large number of unspecified comforts such as a supermarket and a convenience store. Moreover, since the set temperature is set lower as the outside air temperature is higher, the power consumption increases.
Furthermore, since the above-described prior art sets the indoor temperature lower as the outdoor temperature is higher, the temperature difference between the indoor temperature and the outdoor temperature increases, and the temperature changes suddenly and feels uncomfortable when entering and exiting the indoor space. Sometimes. Moreover, since it controls individually in illumination control, it aims at providing the air-conditioning illumination interlocking | linkage system from which more effective power saving property and comfort are obtained from a user side.

上記課題を解決するために、日射量（輻射熱）を検出するセンサを共通化して空調及び照明器具をトータル的に制御する。空気調和機器は、外気温度が高いほど室内温度が高くなるような設定温度パターンを備え、さらに日照量が多い場合は暖かく感じるので、日照量を検知して日照量が多い場合は空気調和制御の設定温度を下げるとともに、同一検知センサの信号を受けて照明器具の調光度を連動して制御をする。  In order to solve the above problems, a sensor for detecting the amount of solar radiation (radiant heat) is used in common to control the air conditioner and the lighting equipment in total. Air conditioning equipment has a set temperature pattern in which the indoor temperature increases as the outside air temperature increases, and it feels warmer when the amount of sunlight is large. In addition to lowering the set temperature, the dimming degree of the luminaire is controlled in conjunction with the signal from the same detection sensor.

本発明によれば、室外温度が高いほど室内温度が高くなるように空気調和装置を制御することによって、室外から室内に入ったときや室内から室外へ出たときの温度変化の急変が緩和でき快適性が得られるとともに空気調和装置の省電力化が図れる。また、同一センサで照明装置を連動して制御する事により総合的な省電力化が図れる。  According to the present invention, by controlling the air conditioner so that the higher the outdoor temperature, the higher the indoor temperature, the sudden change in temperature change when entering the room from the outside or when leaving the room from the outside can be alleviated. Comfort can be obtained and power saving of the air conditioner can be achieved. Moreover, comprehensive power saving can be achieved by controlling the lighting device in conjunction with the same sensor.

本発明の最良の実施の形態について、図を用いて説明する。図１は、本発明の一実施形態を示している。図１は店舗内部を示した室内空間１で、左側壁には大きな窓６を備えている。室内空間１には天井窓側に照明装置１１が、中央及び奥側に照明装置１５が設置され、フロアには商品棚１２，１３や冷蔵ショーケース１４などが設置されている。また空気調和装置１０の室内機２が天井付近に設置されている。室内機２は冷媒配管４によって空気調和装置１０の室外機３と接続されている。室内空間１には照明および空気調和設定制御の制御装置５が設置されており、空気調和装置１０及び照明装置１１，１５をコントロールしている。室内機２の室内空気吸い込み口付近には室内温度センサ２Ａが取り付けられており室内温度を検知し、設定温度になるように制御されている。室外機３には室外温度を検知する室外温度センサ３Ａと切り換えスイッチ３Ｂが取り付けられている。また天井付近には窓６の日射量（輻射熱量）が検知できる昼光センサ７が取り付けられている。  The best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment of the present invention. FIG. 1 shows an interior space 1 showing the interior of a store, and a large window 6 is provided on the left side wall. In the indoor space 1, an illumination device 11 is installed on the ceiling window side, an illumination device 15 is installed on the center and the back side, and product shelves 12, 13 and a refrigerated showcase 14 are installed on the floor. The indoor unit 2 of the air conditioner 10 is installed near the ceiling. The indoor unit 2 is connected to the outdoor unit 3 of the air conditioner 10 by the refrigerant pipe 4. A control device 5 for controlling lighting and air conditioning setting is installed in the indoor space 1 to control the air conditioning device 10 and the lighting devices 11 and 15. An indoor temperature sensor 2A is attached in the vicinity of the indoor air intake port of the indoor unit 2, and the indoor temperature is detected and controlled so as to reach a set temperature. An outdoor temperature sensor 3A for detecting the outdoor temperature and a changeover switch 3B are attached to the outdoor unit 3. A daylight sensor 7 capable of detecting the amount of solar radiation (radiant heat) of the window 6 is attached near the ceiling.

次に空気調和装置１０の設定温度の一実施例を図２および図３で説明する。図２は冷房設定温度を示したものである。パターン１の設定は室外温度が２８℃未満で設定温度を２６℃、室外温度が２８℃以上かつ３２℃未満で設定温度を２７℃、室外温度が３２℃以上で設定温度を２８℃と、外気温度が高いほど設定温度を高くしている。図３は暖房設定温度を示したものである。パターン１の設定は室外温度が７℃未満で設定温度を１９℃、室外温度が７℃以上かつ１５℃未満で設定温度を２１℃、室外温度が１５℃以上で設定温度を２２℃と、外気温度が高いほど設定温度を高くしている。  Next, an example of the set temperature of the air conditioner 10 will be described with reference to FIGS. FIG. 2 shows the cooling set temperature. The setting of pattern 1 is that the outdoor temperature is less than 28 ° C, the set temperature is 26 ° C, the outdoor temperature is 28 ° C or more and less than 32 ° C, the set temperature is 27 ° C, the outdoor temperature is 32 ° C or more, and the set temperature is 28 ° C. The higher the temperature, the higher the set temperature. FIG. 3 shows the heating set temperature. The setting of pattern 1 is that the outdoor temperature is less than 7 ° C, the set temperature is 19 ° C, the outdoor temperature is 7 ° C or more and less than 15 ° C, the set temperature is 21 ° C, the outdoor temperature is 15 ° C or more, and the set temperature is 22 ° C. The higher the temperature, the higher the set temperature.

図２のパターン２は設定温度パターン１に対して、１℃下げたものである。図３のパターン２は設定温度パターン１に対して、１℃下げたものである。設定温度パターンの選択は図４に示すように室外機３に設けられた切り換えスイッチ３Ｂによって行う。冷房および暖房とも設定温度パターン１の場合は切り換えスイッチ３ＢのＡスイッチおよびＢスイッチをオンにする。冷房設定温度をパターン１で暖房設定温度をパターン２の場合はＡスイッチをオン、Ｂスイッチをオフにする。冷房設定温度をパターン２で暖房設定温度をパターン１の場合はＡスイッチをオフ、Ｂスイッチをオンにする。冷房および暖房とも設定温度パターン２の場合はＡスイッチおよびＢスイッチをオフにする。  Pattern 2 in FIG. 2 is obtained by lowering the set temperature pattern 1 by 1 ° C. Pattern 2 in FIG. 3 is a temperature lowered by 1 ° C. with respect to the set temperature pattern 1. The set temperature pattern is selected by a changeover switch 3B provided in the outdoor unit 3 as shown in FIG. In the case of the set temperature pattern 1 for both cooling and heating, the A switch and B switch of the changeover switch 3B are turned on. When the cooling set temperature is pattern 1 and the heating set temperature is pattern 2, the A switch is turned on and the B switch is turned off. When the cooling set temperature is pattern 2 and the heating set temperature is pattern 1, the A switch is turned off and the B switch is turned on. In the case of the set temperature pattern 2 for both cooling and heating, the A switch and the B switch are turned off.

図２および図３に示す設定温度パターンは図１に示す窓６の日射量（輻射熱量）を検知する昼光センサ７によって日射があるかないかを判断して切り換えられる。冷房設定の設定温度パターン１は日射なしの設定温度と同様である。設定温度パターンの日射ありは日射なしの設定温度パターン１に対して、１℃下げたものである（パターン２）。
図３の暖房設定も同様に設定温度パターンの日射なしは前述のパターン１と同様である。設定温度パターンの日射ありは日射なしの設定温度パターン１に対して、１℃下げたものである（パターン２）。冷房室内温度を２５℃で暖房室内温度を２２℃で運転した場合の空気調和機の年間消費電力量と図２および図３の日射を考慮した設定温度パターンで運転した場合の空気調和機の年間消費電力量を計算比較すると冷房室内温度を２５℃で暖房室内温度を２２℃で運転した場合に比べて、１６．０％の省電力効果が得られる。The set temperature patterns shown in FIGS. 2 and 3 are switched by determining whether or not there is solar radiation by a daylight sensor 7 that detects the solar radiation amount (radiant heat amount) of the window 6 shown in FIG. The set temperature pattern 1 for the cooling setting is the same as the set temperature without solar radiation. The presence of solar radiation in the set temperature pattern is 1 ° C. lower than the set temperature pattern 1 without solar radiation (pattern 2).
The heating setting in FIG. 3 is the same as the above-described pattern 1 except that the set temperature pattern has no solar radiation. The presence of solar radiation in the set temperature pattern is 1 ° C. lower than the set temperature pattern 1 without solar radiation (pattern 2). Annual operation of the air conditioner when operating with a set temperature pattern that takes into consideration the annual power consumption of the air conditioner and the solar radiation of FIGS. 2 and 3 when the cooling room temperature is 25 ° C. and the heating room temperature is 22 ° C. When the power consumption is calculated and compared, a power saving effect of 16.0% can be obtained as compared with the case where the cooling room temperature is 25 ° C. and the heating room temperature is 22 ° C.

照明装置１１は図６に示す通り、日射量の検知レベル１，０００ＬＸの閾値に対して１，０００ＬＸ以上の場合、窓６から日射が多く室内６に入るため窓側エリアが明るくなる分、照明装置１１の明るさを下げて（実施例では２５％の調光度）省電力をはかり、調光度を下げることにより照明装置器具１１からの発熱量も低下することにより冷房負荷の負担を軽くする効果もある。昼光利用による消費電力低減効果は制御をしない場合に比べ約２０％の省電力効果が得られる。
制御装置５は空気調和装置１０及び照明装置１１，１５に共用のものであり、それらおよび昼光センサ７とアクセスする。制御装置５はプログラム手段をもつ。制御装置５は日射量を検知する手段となる昼光センサ７の出力に応動して空気調和装置１０及び照明装置１１，１５を前記のごとくに制御する。As shown in FIG. 6, the lighting device 11 has an amount of light that is brightened in the window-side area because there is a lot of solar radiation from the window 6 and enters the room 6 when the solar radiation amount detection level is 1,000 LX or more with respect to the threshold of 1,000 LX. 11 is reduced (25% dimming degree in the embodiment) to save power, and by reducing the dimming degree, the amount of heat generated from the lighting device fixture 11 is also reduced, thereby reducing the cooling load. is there. The effect of reducing power consumption by using daylight is about 20% less than that when not controlling.
The control device 5 is shared by the air conditioner 10 and the lighting devices 11 and 15, and accesses them and the daylight sensor 7. The control device 5 has program means. The control device 5 controls the air conditioner 10 and the lighting devices 11 and 15 as described above in response to the output of the daylight sensor 7 which is a means for detecting the amount of solar radiation.

太陽の入射光は昼光センサ７の取付ける方位によって窓６から室内１へ入る量が変化するため、図５に示す通り方位によって設定の閾値を可変できる機能を持たせる。また、入射光は太陽高度によっても前記と同様に室内１へ入る量が変化するため、太陽高度の変化を、前記昼光センサの方位とともに、年間タイマー、本制御システムを取付る設置地域（経度・緯度）の要因を制御装置５で設定してこれらの要素で前記設定の閾値を可変して制御することにより時々刻々に変化する日射量に的確に対応する事が可能となる。この空気調和装置と照明装置を連動して制御する事により、大幅な省電力効果が得られる。
前記方位のデータは昼光センサ７から制御装置５に配信される。年間タイマー、現在地を示す経度・緯度のデータは制御装置５が保有する。Since the amount of the incident light of the sun entering the room 1 from the window 6 varies depending on the direction in which the daylight sensor 7 is attached, the setting threshold value can be varied depending on the direction as shown in FIG. In addition, since the amount of incident light entering the room 1 changes depending on the solar altitude as well, the change in the solar altitude, along with the direction of the daylight sensor, is installed in the installation area (longitude of the yearly timer and this control system). It is possible to accurately cope with the amount of solar radiation that changes from moment to moment by setting the factor of latitude) by the control device 5 and controlling the setting threshold value with these factors. By controlling the air conditioner and the lighting device in conjunction with each other, a significant power saving effect can be obtained.
The azimuth data is distributed from the daylight sensor 7 to the control device 5. The controller 5 holds the yearly timer and longitude / latitude data indicating the current location.
