BS EN 378-3:2016EN 378-3:2016 (E) 6 Introduction The introduction of EN 378-1 is applicable. BS EN 378-3:2016EN 378-3:2016 (E) 7 1
30、 Scope This European Standard specifies the requirements for the safety of persons and property, provides guidance for the protection of the environment and establishes procedures for the operation, maintenance and repair of refrigerating systems and the recovery of refrigerants. The term “refrigera
31、ting system” used in this European Standard includes heat pumps. This Part 3 of the European Standard is applicable to the installation site (plant space and services). It specifies requirements on the site for safety, which may be needed because of, but not directly connected with, the refrigeratin
32、g system and its ancillary components. This standard applies: a) to refrigerating systems, stationary or mobile, of all sizes except to vehicle air conditioning systems covered by a specific product standard e.g. ISO 13043; b) to secondary cooling or heating systems; c) to the location of the refrig
33、erating systems; d) to replaced parts and added components after adoption of this standard if they are not identical in function and in the capacity. Systems using refrigerants other than those listed in of EN 378-1:2016, Annex E are not covered by this standard. This standard does not apply to good
34、s in storage. This standard is not applicable to refrigerating systems which were manufactured before the date of its publication as a European Standard except for extensions and modifications to the system which were implemented after publication. This standard is applicable to new refrigerating sy
35、stems, extensions or modifications of already existing systems, and for existing stationary systems, being transferred to and operated on another site. This standard also applies in the case of the conversion of a system for another refrigerant type, in which case conformity with the relevant clause
36、s of parts 1 to 4 of the standard shall be assessed. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

44、itions and abbreviated terms For the purposes of this document, the terms, definitions and abbreviated terms given in EN 378-1:2016 apply. 4 Location of refrigerating equipment 4.1 General Refrigerating equipment may be sited outside the building in the open air or in a machinery room or in occupied
45、 areas or in unoccupied areas not designated as a machinery room. NOTE The refrigerating equipment can be contained in a ventilated enclosure provided by the manufacturer. Requirements for this enclosure are given in EN 3782:2016, 6.2.15. 4.2 Refrigerating equipment located in the open air Refrigera
46、ting systems sited in the open air shall be positioned to avoid leaked refrigerant flowing into a building or otherwise endangering people and property. The refrigerant shall not be able to flow into any ventilation fresh air opening, doorway, trap door or similar opening in the event of a leak. Whe
47、re a BS EN 378-3:2016EN 378-3:2016 (E) 9 shelter is provided for refrigerating equipment sited in the open air it shall have natural or forced ventilation. A room, where at least one of the longer walls is open to the outside air by means of louvres with 75 % free area and covering at least 80 % of
48、the wall area (or the equivalent if more than one wall is to outside), is considered as being in the open air. For refrigeration systems installed outside in a location where a release of refrigerant can stagnate e.g. below ground, then the installation shall comply with the requirements for gas det
49、ection and ventilation of machinery rooms (see 5.13, Clauses 8 and 9). For refrigerants of class 2L, 2 and 3 requirements regarding ignition sources in EN 378-2:2016, 6.2.14 shall apply where appropriate. 4.3 Refrigerating equipment located in a machinery room When a machinery room is chosen for the location of the refrigerating equipment it shall meet the requirements specified in 5.1 to 5.14.
