Abstract

<P>PROBLEM TO BE SOLVED: To restrain or prevent temperature rising or lowering, or the dew condensation of a control panel installed outdoors without using a temperature/humidity control apparatus. <P>SOLUTION: Ceramic coating is applied to at least the outer surface of a casing of the control panel mounted with a programmable logic controller in the casing. By this constitution, the temperature in the casing can be restrained from rising and lowering. While the temperature of the outside air rises, the temperature rise in the casing can be restrained so as to be in its allowable range. While the temperature lowers on the other hand, the temperature lowering in the casing can be restrained so as to be in the allowable range. Temperature variations in the casing can be regulated like this, thus preventing the generation of dew condensation. <P>COPYRIGHT: (C)2004,JPO

Description

【発明の属する技術分野】
本発明は、屋外に設置する制御盤筐体の外面や内面にセラミックス系塗料を塗布することにより、夏季の筐体内部の温度上昇,冬季の温度低下や、急激な温度変化による結露の発生を抑制する制御盤に関する。
【0002】
【従来の技術】
従来の技術としては、例えば特開2001−262072号公報に記載のように、屋外建築物,貯蔵タンク,輸送用コンテナ等の外面に、遮光熱塗材を塗布することで太陽光直射による内部温度の上昇を防ぎ、LPガス,石油等の危険物や穀物の温度上昇を防止する遮光熱塗材が開示されている。そして、塗材として太陽光の光エネルギー波長域0.2〜2.5μmを効率よく反射させる性能を持つ太陽光反射セラミックスフィラーを主材とし、これに熱伝導度及び比熱が小さい性質を持つ水溶性化学反応樹脂溶液をバインダーとするもので、塗膜厚が70μmの厚さになるように塗装することが記載されている。
【0003】
【発明が解決しようとする課題】
特開2001−262072号公報に記載の従来の技術は、断熱塗料の塗布は屋外建築物,貯蔵タンク,輸送用コンテナ,穀物サイロ等の外面に塗布するものであり、夏季の日射の遮光性を目的としたものである。
【0004】
屋外に設置する制御盤の場合は、夏季の温度上昇をなるべく低く抑える対策の他に、冬季には温度低下をなるべく抑える対策や結露対策も必要である。このため、一般的には、冷却ファン,クーラー,除湿器等の温湿度制御機器を制御盤内部に実装する、あるいは筐体外部に日射遮蔽板を取付ける等の対策がとられている。
【0005】
制御盤内に冷却ファン,クーラー,除湿器等を実装しても、制御盤は屋外に設置されているので、その温湿度制御の能力不足により結露が発生することがあった。この結露によって、筐体内部に実装されているコントローラや入出力装置等の制御機器類に深刻な影響を及ぼす事が懸念されている。また、近年、制御盤のメンテナンスフリー化が望まれており、昨今急務となっている環境保護の点からも、消費電力を極力抑え、CO の排出量を抑制する等の環境を考慮した製品設計が求められている。
【0006】
このため、制御盤の筐体への断熱塗装は有効な方法であるが、特開2001−262072号公報に記載の従来の技術では、塗装厚が70μmの厚さになるように塗装しているものであるので、冬季の温度低下をなるべく抑える対策,結露対策には十分でないものであった。
【0007】
本発明の目的は、制御盤の筐体を塗装することにより、筐体内の温度上昇や下降,温度の急激な変化による結露発生を抑制できる制御盤を提供することにある。
【0008】
本発明の他の目的は、屋外に設置する制御盤筐体にセラミックス系塗料を塗布することにより、屋外環境でも制御盤筐体内部の夏季の温度上昇抑制や冬季の温度下降抑制,結露の発生を抑制できる制御盤を提供することにある。
【0009】
【課題を解決するための手段】
上記目的を達成するために本発明による制御盤は、少なくとも筐体の側面部外表面,天井部外表面,扉の外表面にセラミックス系塗料を厚く塗布して、夏季の直射日光や照り返しによる筐体内温度上昇を抑制し、冬季における外気温低下に伴う筐体内温度低下、及び外気温変化に起因した筐体内部の急激な温度変化による結露の発生を抑制するものである。
【0010】
【発明の実施の形態】
本発明の一実施例を図1から図5により説明する。図1は、上下水道用プラント向けで屋外に設置される自立型の制御盤(現場操作盤ともいう)の全体構成を示す斜視図である。
【0011】
図1に示すように、ベース11の上に制御盤の筐体が載置され、制御盤の筐体内には、プログラマブルロジックコントローラ1,ファン2が設けられている。プログラマブルロジックコントローラ1は発熱している発熱体であり、発熱体はこの他にも運転回路等があり、制御盤の筐体内に設置されている。ファン2により制御盤内の空気は排気口から排出される。
【0012】
筐体の正面には操作用の表示ボタン3が取付けられており、正面扉4に設けられたガラス窓5を見ることにより、表示ボタン3の表示内容を確認することができるようになっている。図3に示すように、正面扉4の外側には名称銘板12,社名銘板13,ハンドル14が取付けられ、ハンドル14を回して扉4の開閉を行う。筐体は、図2に示す左側板6,図4に示す右側板7,図5に示す背面板8,天井部9,扉4で構成されており、左側板6,右側板7,背面板8,天井部9及び扉4それぞれの外表面に、セラミックス系塗料を2回塗りして塗膜厚が0.6mm〜0.8mm となるように塗布している。以下、外表面に塗布する例で説明するが、それぞれの内表面にもセラミックス系塗料を2回塗りして塗膜厚が0.6mm〜0.8mmとなるように塗布すると、より効果がある。
【0013】
セラミックス系塗料は、例えば水溶性アクリル樹脂にセラミックスを混和した塗料であり、ベース樹脂としてアクリル樹脂,ウレタン樹脂,シリコン樹脂等を用い、配合するセラミックスとして珪素系セラミックス等を用いる。塗布作業は、ガン吹き付け塗り,刷毛塗り,ローラー塗り等により行われる。塗装色はセラミックス自体の色である白色が一般的であるが、水性着色料により、白色以外の色に着色することができる。
【0014】
外表面にセラミックス系断熱塗料を2回塗りで塗膜厚を約0.8mm 塗布し、プログラマブルロジックコントローラ1の近くの測定位置10にて内部の温度,湿度,筐体付近の外気温度,湿度を一週間連続して測定した結果を表1に示す。

図6は、本発明の他の実施例である上下水道用プラント向けで屋外に設置されるスタンド型の制御盤の全体構成を示す斜視図である。
【0018】
ベース11上には、スタンド盤足が設置され、スタンド盤足には筐体が載置されている。制御盤の筐体内には、図1に示す例と同様に、プログラマブルロジックコントローラ1等の発熱体,ファン2が設けられており、制御盤内の空気を排気している。
【0019】
筐体の正面には操作用の表示ボタン3が取付けられており、正面扉4に設けられたガラス窓5を見ることにより、表示ボタン3の表示内容を確認することができるようになっている。図8に示すように、正面扉4の外側には名称銘板12,社名銘板13,ハンドル14が取付けられ、ハンドル14を回して扉4の開閉を行う。筐体は、図7に示す左側板6,図9に示す右側板7,図10に示す背面板8,天井部9,扉4で構成されており、左側板6,右側板7,背面板8,天井部9,扉4,スタンド盤足左側面部15,スタンド盤足正面部16,スタンド盤足右側面部17及びスタンド盤足背面部18のそれぞれの外表面に、セラミックス系断熱塗料を2回塗りして塗膜厚が0.6mm〜0.8mmとなるように塗布している。正面扉4,左側板6,右側板7,背面板8の外側に、日射遮蔽板を設けてもよく、この場合は、日射遮蔽板の外表面にセラミックス系断熱塗料を2回塗りして塗膜厚が0.6mm〜0.8mmとなるように塗布する。
【0020】
図1に示す例と同様に、外表面にセラミックス系断熱塗料を2回塗りで塗膜厚を約0.8mm 塗布し、プログラマブルロジックコントローラ1の近くの測定位置10にて内部の温度,湿度,筐体付近の外気温度,湿度を一週間連続して測定した結果を表2に示す。

【0022】
表2に示すように、比較例の外気最高温度27℃に対して本実施例の制御盤筐体内部の最高温度は24℃と3℃低く、図1に示す例と比較しても1℃低下しており、筐体内部の温度上昇が抑制されていることが分る。一方、比較例の筐体内部の最低温度が1℃に対し、本実施例の筐体内部の最低温度は5℃であり、筐体内部の温度低下が抑制されていることが分る。湿度に関しても、比較例の最高湿度が100%に対し、本実施例の制御盤筐体内部の最高湿度は82%で18%低下しており、結露の発生を抑制できることが分る。
【0023】
以上述べたように、夏季の直射日光や照り返しによる筐体内部の温度上昇や、冬季の外気温の低下による筐体内部の温度低下,急激な温度変化による筐体内の結露を防止できるので、屋外に設置される制御盤に適用した場合、例えば筐体内部に温度上昇を抑制する冷却器,急激な温度変化による結露を防止するためのスペースヒータ等の温湿度制御機器を制御盤内に実装しなくても、あるいは小型のものにしても、制御盤筐体内部の温度,湿度を実装部品の許容範囲内とでき、結露の発生を防止でき筐体内の発錆や湿度による部品への影響を少なくすることができる。このような制御盤の用途としては、現場設備の近傍に設置され、コントローラ等の発熱体を実装した上下水道プラント向けの現場操作盤,ETC車線サーバー用制御盤がある。
【0024】
又、冷却器等の温湿度制御機器を設置しなくてもよいので、温湿度制御機器の消耗部品の定期交換や保守点検作業がなくなり、メンテナンスフリー化したあるいは保守点検の少ない制御盤が実現できる。又、保守点検作業が少ないので、制御盤の扉の開閉回数を少なくでき、扉の開閉による制御盤内に侵入する塵埃が少なくなり、製品の信頼性が向上できる。又、温湿度制御機器を設置しなくても良いので、制御盤の電力消費量を減らすことができ、近年のCO 排出量の削減要求の観点に合った、環境負荷を軽減する効果が期待できる。
【0025】
【発明の効果】
本発明によれば、温湿度制御機器を制御盤内に実装しなくても、あるいは小型のものにしても、夏季の制御盤筐体内部の温度上昇を抑制でき、冬季における筐体内部の温度低下、及び急激な温度変化による結露を抑制できる効果を奏する。

In the case of a control panel installed outdoors, in addition to measures to keep the temperature rise in summer as low as possible, measures to suppress the temperature fall and condensation in winter are also necessary. For this reason, generally, measures such as mounting a temperature and humidity control device such as a cooling fan, a cooler, and a dehumidifier inside the control panel, or attaching a solar radiation shielding plate outside the housing are taken.
[0005]
Even if a cooling fan, a cooler, a dehumidifier, and the like are mounted in the control panel, dew condensation may occur due to lack of temperature and humidity control capability because the control panel is installed outdoors. There is a concern that this dew may have a serious effect on control devices such as a controller and an input / output device mounted inside the housing. In recent years, control panel has a maintenance-free is desired, in terms of environmental protection has become an urgent need today, minimizing power consumption, taking into account the environment such as to suppress the emission of CO 2 product Design is required.
