Omfang

This part of EN 255 specifies minimum requirements which ensure that a air or water cooled air conditioner, liquid chilling packages, air/air, water/air, air/water or water/water heat pump, with electrically driven compressor, is fitted for the use designated by the manufacturer, when used for space heating or for hot sanitary water. When these units are used for space cooling, then EN 814-3 applies; when these units are used for liquid cooling and heat recovery, then prEN 12055 applies. This standard also specifies recommendations for the way the characteristics of units shall be specified by the manufacturer in order to assist users and manufacturers in the understanding and comparison of various types. This standard applies to factory-made units which can be ducted. In the case of units consisting of several parts, the standard applies only to those designed and supplied as a complete package. Units having two or more indoor sections connected to a single outdoor unit (multiple split system air conditioners or heat pumps) are excluded from this standard. This standard does not apply to continuously variable capacity control units. Installations used in industrial processes are not within the scope of this standard.
