(Main)Specifications for dedicated liquefied petroleum gas appliances - Absorption refrigerators
Specifications for dedicated liquefied petroleum gas appliances - Absorption refrigerators
This standard specifies the constructional and operational characteristics, the safety requirements, test methods and marking of absorption refrigerators for use with butane, propane and their mixture in the vapour phase.
This standard is applicable to room sealed (Type C11) and (Type A1) as defined in EN 1749, refrigerators using gas equipment fuelled by third family gases (LPG).
This standard is applicable for:
- portable cooling appliances
- refrigerating appliances installed in vehicles, caravan holiday homes, boats, or leisure lodges.
Note 1: Boats considered in this standard are recreational crafts covered by European Directive 2012/53/EU.
The gas consumption of absorption refrigerators is of the same order of magnitude as pilots currently used on other types of burners, maximum being 60 g/h. Consequently, efficiency measurement is not considered relevant for these appliances, and it is not covered by this standard.
This standard is also applicable for refrigerator/freezing combinations.
