37、room. 4.2 Refrigerating equipment located outside in the open air Refrigerating equipment sited in the open shall be positioned to avoid refrigerant leaking into the building or otherwise endanger people. If sited on the roof the refrigerant shall not be able to flow across the roof into any ventila

38、tion fresh air opening, doorway, trap door or similar opening in the event of a leak. A shelter provided for refrigerating equipment sited in the open air shall be provided with natural or forced ventilation. Refrigerating equipment located in the open air shall be sited to avoid refrigerant leakage

39、 into adjacent buildings or other danger to people. NOTE A room, where at least one of the longest walls is open to the outside air by means of louvres with 75 % free area and covering at least 80 % of the wall area (or the equivalent if more than one wall is to outside), is considered as being in t

40、he open air. 4.3 Refrigerating equipment located inside in a machinery room When a machinery room is chosen for the location of all the refrigeration equipment or for the high pressure side of the system, it shall meet the requirements of 5.1 to 5.15. Where the charge of a refrigerant is above the p

41、ractical limits specified in EN 378-1 the refrigerating system shall only be permitted in a special machinery room. !deleted text“ NOTE 1 Additional requirements may be needed for refrigerating systems containing B2, B3, A2, and A3 refrigerants as specified in 5.17. NOTE 2 Where housing around refri

42、gerating equipment is sufficiently large for people to enter then the housing should be considered as a machinery room and requirements for such rooms apply. 4.4 Refrigerating equipment located in an occupied space The requirements shall be as specified in !EN 378-1:2008+A2:2012“. 4.5 Refrigerating

43、equipment located in an unoccupied space not designated a machinery room If the area is sealed from any occupied space, the requirements shall be as those for a machinery room. If the space cannot be sealed from any occupied space then the refrigerating machinery shall be considered as located in th

44、e occupied space and requirements for such spaces shall apply. 4.6 Refrigerating equipment located within a ventilated enclosure The ventilated enclosure containing the refrigerating system shall have a ventilation duct as specified by the manufacturer. The duct shall be no greater in length and sha

45、ll have no more bends than the maximum number specified by the manufacturer. The room in which the ventilated enclosure is installed shall be at least ten times the volume of the enclosure and shall have sufficient make up air to replace any exhausted air. The ventilation form the enclosure shall be

46、 to the outside air or to a room having a minimum volume specified in EN 378-1 for an occupied space.

48、reasons of safety. NOTE Housings kept tight and vented can also serve as machinery rooms. The following principles apply to machinery rooms and special machinery rooms when accommodating refrigerating systems: a) machinery rooms may serve for accommodating refrigerating equipment but need not serve exclusively for this equipment; b) refrigerant gas escaping from machinery rooms shall be prevented from enter
