This European Standard specifies requirements for safety and environmental aspects in relation to operation, maintenance, and repair o
26、f refrigerating systems and the recovery, reuse and disposal of all types of refriger-ant, refrigerant oil, heat transfer medium, refrigerating system and part thereof. These requirements are intended to minimise risks of injury to persons and damage to property and the envi-ronment resulting from i
27、mproper handling of the refrigerants or from contaminants leading to system break-down and resultant emission of the refrigerant. Certain clauses and subclauses of this European Standard are not applicable to unit systems self contained systems and systems built on site which operate with charges of
28、 refrigerant up to 3 kg of refrigerant. These subclauses are 4.1.1, 4.1.2, 4.2, 4.3, 5.1.1 to 5.1.4, 5.2, 5.3.1, 5.3.3 and 6.6. For these systems, the necessary maintenance has to be described in the instruction manual and should repairs be necessary, contact the nearest authorised repair service ce

33、 General requirements 4.1 Operational instructions 4.1.1 Care shall be taken to ensure that the personnel charged with the operation, supervision and mainte-nance of the refrigerating system are adequately instructed and are competent with respect to their tasks. The installer of the refrigerating s
34、ystem shall draw attention to the necessity for adequate instruction of operating and supervising personnel. 4.1.2 Personnel in charge of the refrigerating system that contain more than 3 kg of refrigerant shall have knowledge and experience of the mode of functioning, operation and day-by-day monit
35、oring of this system. 4.1.3 The mixing of different refrigerants within a system is not permitted under any circumstances. In the event of a change of the refrigerant type, it shall be done in accordance with 5.4. 4.2 Instruction of operating personnel Before a new refrigerating system is put into s
36、ervice, it shall be ensured that the operating personnel are instructed on the basis of the instruction manual about the construction, supervision, operation and mainte-nance of the refrigerating system, as well as the safety measures to be observed, if necessary the required personal protection equ
37、ipment (see !EN 378-3:2008+A1:2012“, Annex A) and the properties and han-dling of the refrigerant used. NOTE It is advisable that the operating personnel are present during evacuation, charging with refrigerant and adjustment of the refrigerating system as well as, if possible, during assembly on si
38、te. 4.3 Documentation 4.3.1 The owner / operator shall keep an updated logbook of the refrigerating system if the refrigerant charge exceeds 3 kg. 4.3.2 In the logbook the following information shall be recorded: a) details of all maintenance and repair work; b) quantities and kind of (new, reused o
39、r recycled) refrigerant which have been charged on each occasion, and the quantities of refrigerant which have been transferred from the system on each occasion, see also 6.6; c) analysis of a reused refrigerant, if available, the results of which shall also be kept in the log-book; d) source of the
40、 reused refrigerant; e) changes and replacements of components of the system; f) results of all periodic routine tests; g) record of significant periods of non-use. 4.3.3 The log-book shall either be kept by the owner / operator and in the machinery room, or the data shall be stored in a computer wi
41、th a printout in the machinery room, in which case the information shall be accessi-ble to the competent person when servicing or testing.

NOTE 1 The frequency of such maintenance depends on the type, size,
43、age, use etc. of the system. In many cases more than one maintenance service is required in the course of one year in accordance with legal requirements. NOTE 2 For personal protective equipment against refrigerants see EN 378-3. 5.1.2 The user / owner concerned for the refrigerating system shall en
44、sure that the system is inspected, regularly supervised and maintained in a satisfactory manner. 5.1.3 Systems with a charge larger than 3 kg should be subject to tightness inspection at least on an annual basis. If, during the inspection the suspicion of a leak exists, e.g. through refrigerant temp
45、erature checks or capacity reduction, then leak has to be located with suitable detection equipment and should be repaired and checked again after the repair in accordance with national regulations. The results of the inspection and measures taken afterwards should be included in the logbook. Refer
46、to Annex D for detailed specification regarding in service inspection. 5.1.4 The parties concerned for the refrigerating system shall also be responsible when another person uses the refrigerating system, unless another division of responsibility has been agreed upon. 5.1.5 Regular maintenance which
47、 does not include interference with, nor adjustment of, the refrigerating system and which requires no specialised knowledge of refrigeration can be carried out by a person of appro-priate competence employed by the person responsible. Examples of such non-specialist maintenance include air-side cle
48、aning of heat exchangers, cleaning of condensate systems. 5.1.6 It is not permitted to charge a refrigerating system with a refrigerant type that does not comply with the machine card nor with the specifications of the manufacturer. In the case of appliances, the refrigerant type has to conform to the rating label data. In the case of retrofitting of an installation, see 5.4. 5.1.7 In the case of refrigerating systems located within an enclosure and considered as indirect systems under EN 378-1, no unauthorised persons shall remain in the occupancy du
