装置に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-site control panel apparatus for cooling a control panel installed in a building where on-site equipment (plant equipment) such as a boiler or a turbine is installed.

Description of the Related Art Generally, a control panel containing a control device including electronic components such as an input / output device is installed in a central control room having an air conditioner and good environmental conditions. In recent years, the number of input / output points of the control device has increased significantly, and the number of signal cables has also increased. When the number of signal cables increases, the laying work also increases significantly.

れ増加傾向にある。In order to solve this problem, it has been studied to install a control panel containing a control device in a building where field equipment (plant equipment) such as a boiler or a turbine is installed. Input / output control panel installed on site is 20 ~
The number is 30 or more, and it tends to increase as the automation range of the plant increases.

め、盤内温度の上昇を抑えることが必要となる。[0004] However, the surrounding environment is poor at the site, the amount of dust is large, and the ambient temperature is high. When the control panel is installed near a boiler or a turbine, the ambient temperature exceeds 40 ° C. and becomes higher in summer. The control panel has to be closed because the surrounding environment is bad, and the temperature inside the panel rises further by 20 to 30 ° C. than the ambient temperature. Since the temperature in the panel becomes 55 ° C. or more, which is the limit temperature of the electronic device constituting the control device, it is necessary to suppress the rise in the temperature in the panel.

器の近くに分散位置されるので経済的に得策でない。[0005] In order to suppress the rise in the temperature inside the control panel, it is conceivable to provide a centralized air-conditioning room in the site building. However, the number of control panels is as large as 20 to 30 or more.
It is not economically advantageous because the control panel is distributed near plant equipment and detectors to reduce the amount of signal cables.

開平５８―８３５０７号公報に記載されている。[0006] Conventionally, it has been known that, for forcibly cooling the control panel, a refrigerant generated by a cooling device is recirculated in the control panel to suppress an increase in the temperature inside the panel. This is described, for example, in JP-A-58-83507.

う問題点を有する。また、常時冷却装置を冷房運転する
ことは結露の問題が付随して発生する。In the prior art, the control panel is forcibly cooled by circulating the refrigerant generated by the cooling device in the control panel. However, when the control panel is installed on site, the ambient temperature of the cooling device also increases. When the ambient temperature of the cooling device exceeds about 43 ° C., the compressor becomes inoperable. For this reason, there is a problem that the control panel installed in a place where the ambient temperature becomes high, such as a site building, cannot be reliably cooled. In addition, the cooling operation of the cooling device always involves the problem of condensation.
