Description

本発明は、所定空間内の温度を制御する温度制御システムに関するものである。 The present invention relates to a temperature control system that controls the temperature in a predetermined space.

従来、屋外での使用に対応していない電気機器を屋外に配置して使用したい場合、電気機器を収納装置に収納し、風雨などから保護している。 Conventionally, when an electric device that is not compatible with outdoor use is to be placed and used outdoors, the electric device is stored in a storage device to protect it from wind and rain.

電気機器を収納装置に収納すると、電気機器からの熱や環境温度などによって収納装置内の温度が上昇する。収納装置内の温度が電気機器の動作温度範囲を超えると故障の原因となり、また、熱暴走による誤動作や動作停止の原因となったり、電気機器の保護機能により電気機器がシャットダウンする場合もある。そこで、収納装置内を冷房する冷房装置を設置し、収納装置内の温度の管理を行うことが重要となる。 When an electric device is stored in a storage device, the temperature inside the storage device rises due to heat from the electric device, environmental temperature, or the like. If the temperature inside the storage device exceeds the operating temperature range of the electric device, it may cause a failure, cause a malfunction or stop operation due to thermal runaway, or shut down the electric device due to the protection function of the electric device. Therefore, it is important to install a cooling device that cools the inside of the storage device and control the temperature inside the storage device.

また、電気機器の常時稼働が求められる場合には、無停電電源装置(UPS)を設け、停電時に収納装置内の電気機器に電力を供給できるようにしている。 Further, when the electric equipment is required to be constantly operated, an uninterruptible power supply (UPS) is provided so that electric power can be supplied to the electric equipment in the storage device in the event of a power failure.

特許文献1には、停電時にサーバーの消費電力を低減することで、サーバー室の温度上昇を抑制し、UPSの容量を低減できることが記載されている。 Patent Document 1 describes that by reducing the power consumption of the server in the event of a power failure, the temperature rise of the server room can be suppressed and the capacity of the UPS can be reduced.

特開2019−4542号公報Japanese Unexamined Patent Publication No. 2019-4542

停電時に冷房装置に電力を供給しない場合、停電が長時間になると収納装置内の温度が上昇し、無停電電源装置の容量がまだ残っているにもかかわらず電気機器の稼働が停止したり、電気機器が誤作動したり故障してしまう可能性がある。そのため、停電時には電気機器だけでなく冷房装置にも電力を供給するように構成することが好ましい。この場合、無停電電源装置は電気機器と冷房装置の双方に電力を供給するか、別途冷房装置用の無停電電源装置を設けることになるが、いずれにしろ停電補償時間(負荷に連続給電できる時間)が問題となる。 If power is not supplied to the air conditioner during a power outage, the temperature inside the storage device will rise if the power outage lasts for a long time, and the operation of electrical equipment will stop even though the capacity of the uninterruptible power supply still remains. Electrical equipment may malfunction or break down. Therefore, it is preferable to supply electric power not only to the electric device but also to the cooling device in the event of a power failure. In this case, the uninterruptible power supply supplies power to both the electric device and the cooling device, or a separate uninterruptible power supply for the cooling device is provided, but in any case, the power failure compensation time (the load can be continuously supplied). Time) matters.

停電補償時間を長くする方法として、大容量の無停電電源装置を用いることが考えられるが、コストが増大し、設置容積も増加してしまう問題がある。 As a method of lengthening the power failure compensation time, it is conceivable to use a large-capacity uninterruptible power supply, but there is a problem that the cost increases and the installation volume also increases.

また、冷房装置の設定温度を高く設定しておくことも考えられるが、停電していない場合も室内温度が高くなるため、長期的には電気機器の寿命に影響を与える可能性がある。 It is also conceivable to set the set temperature of the air conditioner high, but since the room temperature rises even when there is no power failure, it may affect the life of the electric device in the long term.

また、特許文献1のように、電気機器の消費電力を低減させることで停電補償時間を長くすることも考えられる。しかし、電気機器側に低消費電力モードの機能が搭載されている必要があり、電気機器を自由に選択できなくなり、高コスト化してしまう。また、一般的に低消費電力モードはパフォーマンスの低下を伴うことも問題である。 Further, as in Patent Document 1, it is conceivable to prolong the power failure compensation time by reducing the power consumption of the electric device. However, it is necessary that the electric device side is equipped with the function of the low power consumption mode, and the electric device cannot be freely selected, resulting in high cost. Another problem is that the low power consumption mode generally accompanies a decrease in performance.

そこで本発明の目的は、非常用電源の停電補償時間を長くすることが可能な温度制御システムを実現することである。また、温度管理が必要な内容物が所定空間内に配置されている場合に、温度がその内容物に影響を与えることを抑制可能な温度制御システムを実現することである。 Therefore, an object of the present invention is to realize a temperature control system capable of prolonging the power failure compensation time of the emergency power supply. Further, it is an object of the present invention to realize a temperature control system capable of suppressing the influence of temperature on the contents when the contents requiring temperature control are arranged in a predetermined space.

When a power failure is detected by the power failure detection unit, the set temperature of the cooling device is set higher than the set temperature when there is no power failure, and when the power failure detection unit detects the restoration of commercial power, the setting of the cooling device is set. It is a temperature control system characterized by returning the temperature to the set temperature when there is no power failure.

また本発明は、所定空間内を設定温度まで暖房する暖房装置と、商用電源の停電時に暖房装置に電力を供給する第1非常用電源と、商用電源の停電および復旧を検出する停電検出部と、を有し、停電検出部により停電を検出した場合、暖房装置の設定温度を停電していない場合の設定温度よりも低くし、停電検出部により商用電源の復旧を検出した場合、暖房装置の設定温度を停電していない場合の設定温度に戻す、ことを特徴とする温度制御システムである。 Further, the present invention includes a heating device that heats a predetermined space to a set temperature, a first emergency power source that supplies power to the heating device in the event of a power failure of a commercial power source, and a power failure detection unit that detects a power failure and restoration of the commercial power source. When a power failure is detected by the power failure detection unit, the set temperature of the heating device is set lower than the set temperature when there is no power failure, and when the power failure detection unit detects the restoration of commercial power, the heating device It is a temperature control system characterized by returning the set temperature to the set temperature when there is no power failure.

また本発明は、所定空間内を冷房設定温度まで冷房し、暖房設定温度まで暖房する冷暖房装置と、商用電源の停電時に冷暖房装置に電力を供給する第1非常用電源と、商用電源の停電および復旧を検出する停電検出部と、を有し、停電検出部により停電を検出した場合、冷暖房装置の冷房設定温度を停電していない場合の冷房設定温度よりも高くし、暖房設定温度を停電していない場合の暖房設定温度よりも低くし、停電検出部により商用電源の復旧を検出した場合、冷暖房装置の冷房設定温度および暖房設定温度を停電していない場合の冷房設定温度および暖房設定温度に戻す、ことを特徴とする温度制御システムである。 Further, the present invention provides a heating / cooling device that cools a predetermined space to a set cooling temperature and heats the heating to a set heating temperature, a first emergency power source that supplies power to the heating / cooling device when a commercial power supply fails, a power failure of the commercial power source, and the like. It has a power failure detection unit that detects recovery, and when a power failure is detected by the power failure detection unit, the cooling set temperature of the heating / cooling device is set higher than the cooling set temperature when there is no power failure, and the heating set temperature is disconnected. If the temperature is lower than the set heating temperature when the power is not set, and when the power failure detector detects the restoration of the commercial power supply, the set cooling temperature and the set heating temperature of the heating / cooling device are set to the set cooling temperature and the set heating temperature when there is no power failure. It is a temperature control system characterized by returning.

本発明において、電気機器を収納する収納装置と、商用電源の停電時に電気機器に電力を供給する第2非常用電源と、をさらに有し、所定空間内は収納装置内であってもよい。 In the present invention, a storage device for accommodating an electric device and a second emergency power source for supplying electric power to the electric device in the event of a power failure of a commercial power source may be further provided, and the predetermined space may be inside the storage device.

Further, when the contents requiring temperature control are arranged in the predetermined space, it is possible to suppress the influence of the temperature on the contents.

以下、本発明の具体的な実施例について説明するが、本発明は実施例に限定されるものではない。 Specific examples of the present invention will be described below, but the present invention is not limited to the examples.

図1は、実施例1の温度制御システムの構成を示した図である。実施例1の温度制御システムは、図1のように、電気機器10を収納する収納装置1と、冷房装置2と、無停電電源装置3(本発明の第1非常用電源に相当)と、停電検出部4と、によって構成されている。 FIG. 1 is a diagram showing a configuration of a temperature control system according to the first embodiment. As shown in FIG. 1, the temperature control system of the first embodiment includes a storage device 1 for accommodating an electric device 10, a cooling device 2, an uninterruptible power supply 3 (corresponding to the first emergency power supply of the present invention), and the like. It is composed of a power failure detection unit 4.

収納装置1は、開閉可能なボックス状容器であり、その内部に電気機器10を収納可能となっている。ここで言う電気機器10は、電力によって動作するあらゆる装置を意味する。また、収納装置1は、無停電電源装置3と接続され、収納装置1内の電気機器10は、収納装置1と接続されており、無停電電源装置3からの電力が収納装置1を介して電気機器10に供給される。 The storage device 1 is a box-shaped container that can be opened and closed, and the electric device 10 can be stored inside the storage device 1. The electric device 10 referred to here means any device operated by electric power. Further, the storage device 1 is connected to the uninterruptible power supply device 3, the electric device 10 in the storage device 1 is connected to the storage device 1, and the electric power from the uninterruptible power supply device 3 is transmitted through the storage device 1. It is supplied to the electric device 10.

冷房装置2は、収納装置1内の温度を測定する温度センサを有し、収納装置1内の温度が設定温度付近となるように冷房する装置である。冷房装置2は、無停電電源装置3と接続されており、無停電電源装置3からの電力が冷房装置2に供給される。 The cooling device 2 is a device that has a temperature sensor that measures the temperature inside the storage device 1 and cools the temperature inside the storage device 1 so that the temperature inside the storage device 1 is close to a set temperature. The cooling device 2 is connected to the uninterruptible power supply device 3, and the electric power from the uninterruptible power supply device 3 is supplied to the cooling device 2.

冷房装置2の設定温度は、商用電源の停電の有無で異なる温度に設定されている。冷房装置2は、停電検出部4に接続されており、停電検出部4からの信号に基づき停電の有無が検出され、その検出に基づき自動的に設定温度が切り替わるように制御される。冷房装置2の冷房方式は任意でよく、たとえば、冷媒を用いた蒸気圧縮式や、ペルチェ素子を用いる方式である。また、温度制御方式も任意の方式でよい。たとえば、冷房動作をオンオフすることで温度制御を行ってもよい。 The set temperature of the cooling device 2 is set to a different temperature depending on the presence or absence of a power failure of the commercial power supply. The cooling device 2 is connected to the power failure detection unit 4, detects the presence or absence of a power failure based on the signal from the power failure detection unit 4, and is controlled so that the set temperature is automatically switched based on the detection. The cooling system of the cooling device 2 may be arbitrary, for example, a vapor compression system using a refrigerant or a system using a Perche element. Further, the temperature control method may be any method. For example, the temperature may be controlled by turning on / off the cooling operation.

商用電源が停電している場合の冷房装置2の設定温度T1は、停電していない場合の設定温度T0よりも高い温度に設定されている。商用電源が停電していない場合の設定温度T0は、常温付近が好ましく、20〜30℃であることが好ましい。また、商用電源が停電している場合の設定温度T1は、T0よりも高く、かつ電気機器10の動作温度範囲の上限以下の温度であれば任意であり、たとえば、35〜45℃に設定する。T1−T0を大きくするほど無停電電源装置3の停電補償時間を長くすることができるので、T1−T0は5℃以上とすることが好ましい。 The set temperature T1 of the cooling device 2 when the commercial power supply is out of power is set to a temperature higher than the set temperature T0 when there is no power outage. The set temperature T0 when the commercial power supply is not out of power is preferably around room temperature, preferably 20 to 30 ° C. Further, the set temperature T1 when the commercial power supply is out of power is arbitrary as long as it is higher than T0 and equal to or lower than the upper limit of the operating temperature range of the electric device 10, and is set to, for example, 35 to 45 ° C. .. Since the power failure compensation time of the uninterruptible power supply 3 can be lengthened as T1-T0 is increased, it is preferable that T1-T0 is set to 5 ° C. or higher.

無停電電源装置3は、収納装置1内の電気機器10および冷房装置2に電力を供給する装置である。商用電源が停電していない場合には、無停電電源装置3に入力された商用電源からの電力が電気機器10および冷房装置2に供給され、商用電源の停電時には、無停電電源装置3内のバッテリからの電力が電気機器10および冷房装置2に供給される。商用電源の電圧、周波数は任意であり、たとえばAC100V、AC200Vである。無停電電源装置3の給電方式は任意の方式でよいが、瞬停に強い常時インバーター給電方式が好ましい。また、無停電電源装置3の出力は、冷房装置2や電気機器10の駆動方式などに応じて選択すればよい。交流電力を出力するものであっても直流電力を出力するものであってもよく、出力電圧、周波数も任意である。3相交流を出力するものであってもよい。 The uninterruptible power supply device 3 is a device that supplies electric power to the electric device 10 and the cooling device 2 in the storage device 1. When the commercial power supply is not out of power, the power from the commercial power supply input to the uninterruptible power supply 3 is supplied to the electric device 10 and the cooling device 2, and when the commercial power supply is out of power, the power in the uninterruptible power supply 3 is supplied. The electric power from the battery is supplied to the electric device 10 and the cooling device 2. The voltage and frequency of the commercial power supply are arbitrary, for example, AC100V and AC200V. The power supply method of the uninterruptible power supply 3 may be any method, but a constant inverter power supply method that is resistant to momentary power failure is preferable. Further, the output of the uninterruptible power supply device 3 may be selected according to the drive system of the cooling device 2 and the electric device 10. It may output AC power or DC power, and the output voltage and frequency are arbitrary. It may output a three-phase alternating current.

なお、無停電電源装置3は、停電時の電力源をバッテリとするものであるが、停電時に電力を供給できる装置であれば無停電電源装置3に限らない。たとえば、停電時の電力源を太陽電池や発電機とするものであってもよいし、それらとバッテリの組み合わせであってもよい。 The uninterruptible power supply 3 uses a battery as a power source at the time of a power failure, but is not limited to the uninterruptible power supply 3 as long as it can supply power at the time of a power failure. For example, the power source at the time of a power failure may be a solar cell or a generator, or may be a combination of these and a battery.

停電検出部4は、商用電源の停電の有無を検出する装置である。停電およびその復旧は、たとえば電圧の変化を検出することによって検出できる。停電検出部4は、停電時および停電からの復旧時にその旨の情報を含む信号を冷房装置2に送信する。なお、停電検出部4は、無停電電源装置3や冷房装置2に機能が組み込まれて一体の装置となっていてもよいし、それらとは別個の装置として設けられていてもよい。 The power failure detection unit 4 is a device that detects the presence or absence of a power failure of the commercial power supply. A power outage and its recovery can be detected, for example, by detecting a change in voltage. The power failure detection unit 4 transmits a signal including information to that effect to the cooling device 2 at the time of a power failure and recovery from the power failure. The power failure detection unit 4 may be integrated with the uninterruptible power supply device 3 or the cooling device 2 or may be provided as a separate device.

次に、実施例1の温度制御システムの動作について説明する。 Next, the operation of the temperature control system of the first embodiment will be described.

商用電源が停電していない場合、商用電源からの電力は無停電電源装置3に入力される。無停電電源装置3は、商用電源からの電力を無停電電源装置3のバッテリの充電に用い、同時に商用電源からの電力を収納装置1および冷房装置2に出力する。収納装置1に入力された電力は、収納装置1内に収納された電気機器10に供給され、電気機器10が駆動される。また、冷房装置2に入力された電力により、冷房装置2はその電気機器10内部が商用電源が停電していない場合の設定温度T0付近となるように冷房する。 If the commercial power supply is not out of power, the power from the commercial power supply is input to the uninterruptible power supply 3. The uninterruptible power supply 3 uses the electric power from the commercial power supply to charge the battery of the uninterruptible power supply 3, and at the same time outputs the electric power from the commercial power supply to the storage device 1 and the cooling device 2. The electric power input to the storage device 1 is supplied to the electric device 10 stored in the storage device 1, and the electric device 10 is driven. Further, the cooling device 2 is cooled by the electric power input to the cooling device 2 so that the inside of the electric device 10 is close to the set temperature T0 when the commercial power supply is not cut off.

商用電源が停電すると、無停電電源装置3は、バッテリの電力を収納装置1および冷房装置2に出力する。そして、バッテリからの電力が収納装置1を介して電気機器10に供給され、電気機器10の駆動が継続される。同様にバッテリからの電力により冷房装置2の駆動も継続される。 When the commercial power supply fails, the uninterruptible power supply 3 outputs the battery power to the storage device 1 and the cooling device 2. Then, the electric power from the battery is supplied to the electric device 10 via the storage device 1, and the driving of the electric device 10 is continued. Similarly, the driving of the cooling device 2 is continued by the electric power from the battery.

また、停電検出部4は商用電源の停電を検出し、停電した旨の情報を含む信号を冷房装置2に送信する。冷房装置2は、その信号を受信し、商用電源が停電したことを検出すると、設定温度をT0よりも高いT1に変更する。設定温度をT1に変更することで、T0のまま冷房装置2の駆動をする場合よりも冷房装置2の消費電力量を抑制することができ、その結果無停電電源装置3の停電補償時間を長くすることができる。 Further, the power failure detection unit 4 detects a power failure of the commercial power source and transmits a signal including information indicating the power failure to the cooling device 2. When the cooling device 2 receives the signal and detects that the commercial power supply has lost power, the cooling device 2 changes the set temperature to T1 which is higher than T0. By changing the set temperature to T1, the power consumption of the cooling device 2 can be suppressed as compared with the case where the cooling device 2 is driven with T0, and as a result, the power failure compensation time of the uninterruptible power supply 3 is extended. can do.

商用電源が復旧すると、無停電電源装置3はその復旧を検知し、バッテリによる電力供給から商用電源による電力供給に戻し、収納装置1および冷房装置2に電力を出力する。また、停電検出部4は、商用電源の復旧を検知し、停電した旨の情報を含む信号を冷房装置2に送信する。冷房装置2は、その信号を受信し、商用電源が復旧したことを検知すると、設定温度を元の設定温度T0に戻す。このように設定温度をT1よりも低いT0に戻すことで、熱が長期的には電気機器10の寿命に影響を及ぼすことを低減することができる。 When the commercial power supply is restored, the uninterruptible power supply 3 detects the restoration, returns the power supply from the battery to the power supply from the commercial power supply, and outputs power to the storage device 1 and the cooling device 2. Further, the power failure detection unit 4 detects the restoration of the commercial power supply and transmits a signal including information indicating the power failure to the cooling device 2. When the cooling device 2 receives the signal and detects that the commercial power supply has been restored, the cooling device 2 returns the set temperature to the original set temperature T0. By returning the set temperature to T0, which is lower than T1, it is possible to reduce the influence of heat on the life of the electric device 10 in the long term.

以上、実施例1の温度制御システムでは、停電時に冷房装置2の消費電力が抑制されるので、無停電電源装置3の停電補償時間を長くすることができる。また、商用電源の復旧後は元の設定温度に戻すので、熱の電気機器10の寿命への影響も低減することができる。実施例1の温度制御システムは、外気温がT0を上回ることの多い地域に好適である。 As described above, in the temperature control system of the first embodiment, since the power consumption of the cooling device 2 is suppressed in the event of a power failure, the power failure compensation time of the uninterruptible power supply device 3 can be lengthened. Further, since the temperature is returned to the original set temperature after the commercial power supply is restored, the influence of heat on the life of the electric device 10 can be reduced. The temperature control system of Example 1 is suitable for an area where the outside air temperature often exceeds T0.

次に、実施例1の温度制御システムに関する具体的な実験結果を説明する。 Next, specific experimental results regarding the temperature control system of Example 1 will be described.

実施例1の温度制御システムから無停電電源装置3と停電検出部4を省き、収納装置1内に700Wの負荷を配置した。冷房装置2の冷房能力は1000Wとした。そして、収納装置1と冷房装置2を35℃の恒温室に配置し、収納装置1および冷房装置2の温度が安定するまで放置した。次に、冷房装置2の設定温度を25℃として、商用電源からの電力を収納装置1内の負荷および冷房装置2に供給した。1時間経過後の冷房装置2の消費電力量は469Whであった。冷房装置2の設定温度を40℃として同様に冷房装置2の消費電力量を測定したところ、249Whであった。この結果、負荷が700Wで冷房能力が1000Wの場合には、停電時に冷房装置2の設定温度を25℃から40℃に変更することで、消費電力量を82%に減らすことができ、無停電電源装置3の停電補償時間を1.2倍に延ばすことが可能であることがわかった。 The uninterruptible power supply 3 and the power failure detection unit 4 were omitted from the temperature control system of the first embodiment, and a load of 700 W was arranged in the storage device 1. The cooling capacity of the cooling device 2 was set to 1000 W. Then, the storage device 1 and the cooling device 2 were placed in a constant temperature room at 35 ° C., and left until the temperatures of the storage device 1 and the cooling device 2 became stable. Next, the set temperature of the cooling device 2 was set to 25 ° C., and the electric power from the commercial power source was supplied to the load in the storage device 1 and the cooling device 2. The power consumption of the cooling device 2 after 1 hour was 469 Wh. When the set temperature of the air conditioner 2 was set to 40 ° C. and the power consumption of the air conditioner 2 was measured in the same manner, it was 249 Wh. As a result, when the load is 700 W and the cooling capacity is 1000 W, the power consumption can be reduced to 82% by changing the set temperature of the cooling device 2 from 25 ° C to 40 ° C in the event of a power failure, and there is no power failure. It was found that the power failure compensation time of the power supply device 3 can be extended 1.2 times.

負荷を250W、冷房装置2の冷房能力を500Wに変更して、同様に冷房装置2の消費電力量を測定したところ、設定温度が25℃では280Wh、40℃では101Whであった。この結果、負荷が250Wで冷房能力が500Wの場合には、停電時に冷房装置2の設定温度を25℃から40℃に変更することで、消費電力量を66%に減らすことができ、無停電電源装置3の停電補償時間を1.5倍に延ばすことが可能であることがわかった。 When the load was changed to 250 W and the cooling capacity of the cooling device 2 was changed to 500 W, and the power consumption of the cooling device 2 was measured in the same manner, the set temperature was 280 Wh at 25 ° C and 101 Wh at 40 ° C. As a result, when the load is 250 W and the cooling capacity is 500 W, the power consumption can be reduced to 66% by changing the set temperature of the cooling device 2 from 25 ° C to 40 ° C in the event of a power failure, and there is no power failure. It was found that the power failure compensation time of the power supply device 3 can be extended by 1.5 times.

図2は、実施例1の温度制御システムの構成を示した図である。実施例2の温度制御システムは、図2のように、実施例1における冷房装置2を暖房装置22に置き換えたものであり、他の構成は実施例1と同様である。 FIG. 2 is a diagram showing the configuration of the temperature control system of the first embodiment. As shown in FIG. 2, the temperature control system of the second embodiment replaces the cooling device 2 in the first embodiment with the heating device 22, and the other configurations are the same as those of the first embodiment.

暖房装置22は、収納装置1内の温度を測定する温度センサを有し、収納装置1内の温度が設定温度付近となるように暖房する装置である。暖房装置22は、無停電電源装置3と接続されており、無停電電源装置3からの電力が暖房装置22に供給される。 The heating device 22 has a temperature sensor that measures the temperature inside the storage device 1, and is a device that heats the storage device 1 so that the temperature inside the storage device 1 is close to a set temperature. The heating device 22 is connected to the uninterruptible power supply device 3, and the electric power from the uninterruptible power supply device 3 is supplied to the heating device 22.

暖房装置22の設定温度は、商用電源の停電の有無で異なる温度に設定されている。暖房装置22は、停電検出部4に接続されており、停電検出部4からの信号に基づき停電の有無が検出され、その検出に基づき自動的に設定温度が切り替わるように制御される。暖房装置22の暖房方式は任意でよい。また、温度制御方式も任意の方式でよい。 The set temperature of the heating device 22 is set to a different temperature depending on the presence or absence of a power failure of the commercial power source. The heating device 22 is connected to the power failure detection unit 4, detects the presence or absence of a power failure based on the signal from the power failure detection unit 4, and is controlled so that the set temperature is automatically switched based on the detection. The heating method of the heating device 22 may be arbitrary. Further, the temperature control method may be any method.

商用電源が停電している場合の暖房装置22の設定温度T2は、停電していない場合の設定温度T0よりも低い温度に設定されている。商用電源が停電している場合の設定温度T2は、T0よりも低く、かつ電気機器10の動作温度範囲の下限以上の温度であれば任意であり、たとえば、0〜5℃に設定する。T0−T2を大きくするほど無停電電源装置3の停電補償時間を長くすることができるので、T0−T2は5℃以上とすることが好ましい。 The set temperature T2 of the heating device 22 when the commercial power supply is out of power is set to a temperature lower than the set temperature T0 when there is no power outage. The set temperature T2 when the commercial power supply is out of power is arbitrary as long as it is lower than T0 and equal to or higher than the lower limit of the operating temperature range of the electric device 10, and is set to, for example, 0 to 5 ° C. Since the power failure compensation time of the uninterruptible power supply 3 can be lengthened as T0-T2 is increased, it is preferable that T0-T2 is set to 5 ° C. or higher.

実施例2の温度制御システムでは、停電時に暖房装置22の消費電力が抑制されるので、無停電電源装置3の停電補償時間を長くすることができる。また、商用電源の復旧後は元の設定温度に戻すので、低温による電気機器10の寿命への影響も低減することができる。実施例2の温度制御システムは、外気温がT0を下回ることの多い寒冷地に好適である。 In the temperature control system of the second embodiment, since the power consumption of the heating device 22 is suppressed in the event of a power failure, the power failure compensation time of the uninterruptible power supply device 3 can be lengthened. Further, since the temperature is returned to the original set temperature after the commercial power supply is restored, the influence of the low temperature on the life of the electric device 10 can be reduced. The temperature control system of the second embodiment is suitable for a cold region where the outside air temperature often falls below T0.

図3は、実施例3の温度制御システムの構成を示した図である。実施例3の温度制御システムは、図3のように、実施例1における冷房装置2を冷暖房装置32に置き換えたものであり、他の構成は実施例1と同様である。 FIG. 3 is a diagram showing the configuration of the temperature control system of the third embodiment. As shown in FIG. 3, the temperature control system of the third embodiment replaces the cooling device 2 in the first embodiment with the air conditioner 32, and other configurations are the same as those of the first embodiment.

冷暖房装置32は、収納装置1内の温度を測定する温度センサを有し、収納装置1内の温度が設定温度付近となるように冷房、暖房する装置である。冷暖房装置32は、無停電電源装置3と接続されており、無停電電源装置3からの電力が冷暖房装置32に供給される。 The air-conditioning device 32 has a temperature sensor that measures the temperature inside the storage device 1, and is a device that cools and heats the storage device 1 so that the temperature inside the storage device 1 is close to a set temperature. The heating / cooling device 32 is connected to the uninterruptible power supply device 3, and the electric power from the uninterruptible power supply device 3 is supplied to the heating / cooling device 32.

冷暖房装置32の設定温度は、商用電源の停電の有無で異なる温度に設定されている。冷暖房装置32は、停電検出部4に接続されており、停電検出部4からの信号に基づき停電の有無が検出され、その検出に基づき自動的に設定温度が切り替わるように制御される。冷暖房装置32の冷暖房方式は任意でよい。また、温度制御方式も任意の方式でよい。 The set temperature of the air conditioner 32 is set to a different temperature depending on the presence or absence of a power failure of the commercial power source. The air conditioner 32 is connected to the power failure detection unit 4, detects the presence or absence of a power failure based on the signal from the power failure detection unit 4, and is controlled so that the set temperature is automatically switched based on the detection. The air-conditioning system of the air-conditioning device 32 may be arbitrary. Further, the temperature control method may be any method.

商用電源が停電している場合の冷暖房装置32の設定温度は、冷房と暖房とで別に設定される。以下、停電している場合の冷房の設定温度を冷房設定温度T1、暖房の設定温度を暖房設定温度T2とする。冷房設定温度T1は、停電していない場合の設定温度T0よりも高い温度に設定され、暖房設定温度T2は、停電していない場合の設定温度T0よりも低い温度に設定されている。冷房設定温度T1は、T0よりも高く、かつ電気機器10の動作温度範囲の上限以下の温度であれば任意であり、たとえば、35〜45℃に設定する。暖房設定温度T2は、T0よりも低く、かつ電気機器10の動作温度範囲の下限以上の温度であれば任意であり、たとえば、0〜5℃に設定する。T1−T0やT0−T2を大きくするほど無停電電源装置3の停電補償時間を長くすることができるので、T1−T0、T0−T2は5℃以上とすることが好ましい。 The set temperature of the air conditioner 32 when the commercial power supply is out of power is set separately for cooling and heating. Hereinafter, the set temperature for cooling in the event of a power failure will be referred to as the set temperature T1 for cooling, and the set temperature for heating will be referred to as the set temperature T2 for heating. The cooling set temperature T1 is set to a temperature higher than the set temperature T0 when there is no power failure, and the heating set temperature T2 is set to a temperature lower than the set temperature T0 when there is no power failure. The cooling set temperature T1 is arbitrary as long as it is higher than T0 and equal to or lower than the upper limit of the operating temperature range of the electric device 10, and is set to, for example, 35 to 45 ° C. The heating set temperature T2 is arbitrary as long as it is lower than T0 and equal to or higher than the lower limit of the operating temperature range of the electric device 10, and is set to, for example, 0 to 5 ° C. Since the power failure compensation time of the uninterruptible power supply 3 can be lengthened as T1-T0 and T0-T2 are increased, it is preferable that T1-T0 and T0-T2 are set to 5 ° C. or higher.

なお、実施例3では停電していない場合の冷房動作の設定温度(冷房設定温度)と暖房動作の設定温度(暖房設定温度)をT0で同一としているが、異なっていてもよい。 In the third embodiment, the set temperature for the cooling operation (cooling set temperature) and the set temperature for the heating operation (heating set temperature) when there is no power failure are the same at T0, but they may be different.

実施例3の温度制御システムでは、停電時に冷暖房装置32の消費電力が抑制されるので、無停電電源装置3の停電補償時間を長くすることができる。また、商用電源の復旧後は元の設定温度に戻すので、高温や低温による電気機器10の寿命への影響も低減することができる。実施例3の温度制御システムは、寒暖の差が激しい地域に好適である。 In the temperature control system of the third embodiment, since the power consumption of the heating / cooling device 32 is suppressed in the event of a power failure, the power failure compensation time of the uninterruptible power supply device 3 can be lengthened. Further, since the temperature is returned to the original set temperature after the commercial power supply is restored, the influence of high temperature and low temperature on the life of the electric device 10 can be reduced. The temperature control system of Example 3 is suitable for an area where the temperature difference is large.

(各種変形例)
実施例1では、商用電源が停電している場合の冷房装置2の設定温度T1は一定としているが、停電していない場合の設定温度T0よりも高ければ一定である必要はない。たとえば、停電時間が長くなるにつれて設定温度が段階的、連続的に高くなるように設定してもよい。実施例2、3についても同様である。
(Various deformation examples)
In the first embodiment, the set temperature T1 of the cooling device 2 when the commercial power supply is out of power is constant, but it does not have to be constant as long as it is higher than the set temperature T0 when there is no power failure. For example, the set temperature may be set to gradually increase as the power failure time increases. The same applies to Examples 2 and 3.

実施例1では、無停電電源装置3を1つ設けて冷房装置2と電気機器10の双方に電力を供給しているが、無停電電源装置3とは別にもう1つ無停電電源装置43(本発明の第2非常用電源)を設け、無停電電源装置3は冷房装置2への電力供給、無停電電源装置43は電気機器10への電力供給として、冷房装置2と電気機器10にそれぞれ個別に電力を供給してもよい(図4参照)。停電時に冷房装置2に電力を供給する無停電電源装置43の停電補償時間を長くすることができる。実施例2、3についても同様である。 In the first embodiment, one uninterruptible power supply 3 is provided to supply electric power to both the cooling device 2 and the electric device 10, but another uninterruptible power supply 43 (separate from the uninterruptible power supply 3) The second emergency power supply of the present invention) is provided, and the uninterruptible power supply 3 supplies power to the cooling device 2 and the uninterruptible power supply 43 supplies power to the electric device 10, respectively. Power may be supplied individually (see FIG. 4). The power failure compensation time of the uninterruptible power supply 43 that supplies power to the cooling device 2 in the event of a power failure can be lengthened. The same applies to Examples 2 and 3.

実施例1〜3は、収納装置内に電気機器10を配置し、電気機器10に電力を供給するとともに収納装置1内を冷房、暖房するものであったが、本発明は収納装置1内の冷房、暖房に限らず、なんらかの所定空間内を冷房、暖房するものであればよい。たとえば、サーバルーム内のコンピュータ等に電力を供給しつつ、サーバルーム内の温度を適切に保つために本発明を適用することができる。 In Examples 1 to 3, the electric device 10 is arranged in the storage device, power is supplied to the electric device 10, and the inside of the storage device 1 is cooled and heated. However, the present invention is in the storage device 1. Not limited to cooling and heating, any predetermined space may be cooled and heated. For example, the present invention can be applied to maintain an appropriate temperature in the server room while supplying electric power to a computer or the like in the server room.

また、本発明は所定空間内の電気機器10への電力供給を行う必要もなく、さらに所定空間内に電気機器10が配置されている必要もない。温度管理が必要な何らかの内容物が所定空間内に配置されていてもよいし、単に所定空間内の温度管理をするものであってもよい。また、所定空間は閉じられた空間である必要はなく、温度制御が可能な範囲であれば一部が開放された空間であってもよい。 Further, the present invention does not need to supply electric power to the electric device 10 in the predetermined space, and further, it is not necessary that the electric device 10 is arranged in the predetermined space. Some contents that require temperature control may be arranged in a predetermined space, or may simply control the temperature in the predetermined space. Further, the predetermined space does not have to be a closed space, and may be a partially open space as long as the temperature can be controlled.

たとえば、コンテナハウスやビニールハウスなどの内部空間内を温度管理するものであってもよい。図5は、実施例3において収納装置1をビニールハウス11に替え、ビニールハウス11内に電気機器10ではなく植物12を配置した例である。無停電電源装置3は停電時に冷暖房装置32に電力を供給する。図5の温度制御システムでは、停電時においてもビニールハウス11内の植物12の状態に影響が出ないように冷暖房することができ、かつ無停電電源装置3の停電補償時間を長くすることができる。 For example, the temperature may be controlled in an internal space such as a container house or a vinyl house. FIG. 5 shows an example in which the storage device 1 is replaced with a vinyl house 11 in the third embodiment, and the plant 12 is arranged in the vinyl house 11 instead of the electric device 10. The uninterruptible power supply 3 supplies electric power to the air conditioner 32 in the event of a power failure. In the temperature control system of FIG. 5, heating and cooling can be performed so that the state of the plant 12 in the vinyl house 11 is not affected even in the event of a power failure, and the power failure compensation time of the uninterruptible power supply 3 can be lengthened. ..

本発明は、FTTHやHFCなどの通信システムにおいて屋外で使用される電気機器(たとえばファイバーアンプやOLT)を収納する収納システムとして有用である。また、内部の温度管理が重要なサーバルームやビニールハウスにも好適である。 The present invention is useful as a storage system for accommodating electrical equipment (for example, a fiber amplifier or OLT) used outdoors in a communication system such as FTTH or HFC. It is also suitable for server rooms and greenhouses where internal temperature control is important.
