An enclosure is an integral part of an electrical accessory that protects that accessory against external influences like mechanical impact, ingress of solid objects or water, etc. Electrical enclosures are especially essential in hazardous areas like petrochemical plants and coal mines.
BS EN 62194 provides a method of thermal performance evaluation for empty indoor enclosures according to IEC 60917 and IEC 60297, and, for outdoor enclosures according to IEC 61969. BS EN 62194 contains criteria to determine the thermal absorption factors relating to principles of enclosure design, internal heat load and sun radiation. The enclosure absorption factor is intended to provide a common value for comparing and selecting enclosures built in accordance with BS EN 62194.
BS EN BS EN 62194 on the thermal performance of enclosures is useful for:
Electronic equipment is used in applications that rely on mechanical or electric systems for their operation. They are essential to any work on electronics systems for creating signals and capturing responses from electronic devices. When installing enclosures with electronic components, the climatic conditions are very important, as the function of the electronics is affected by the ambient temperature. Because of heat load and solar radiation, the enclosures become hot. Since the heat transfer via the enclosure surface is often not sufficient, a climate control unit may be required to maintain tolerable enclosure internal conditions. For the enclosure design, the effect of the solar radiation was either estimated via the solar constant or added with a fixed value for heat load. Closer observation of the radiation allows for a more accurate and cost-efficient method of enclosure thermal performance evaluation.
BS EN 61969-2 discusses terms, definitions, symbols and abbreviations that depict a user-friendly idea of enclosures. BS EN 61969-2 also provides users with environmental conditions and determination of the enclosure absorption factor that contributes to the performance characteristics of outdoor enclosures ensuring their reliability. BS EN 61969-2 helps you evaluate the thermal performance of enclosures that enable you to provide a superior quality product to your customers. BS EN 61969-2 guidelines improve safety and protection and ensure protected electrical equipment
