16、 4754-1:2015-03 5 Foreword This standard includes safety requirements within the meaning of the Produktsicherheitsgesetz (ProdSG) (German Product Safety Act). Where this standard has been identified by the Ausschuss fr Produktsicherheit (German Committee for Product Safety) and reference to it has b
17、een published in the Gemeinsames Ministerialblatt (German Joint Ministerial Gazette) by the Bundesanstalt fr Arbeitsschutz und Arbeitsmedizin (BAuA) (German Federal Institute for Occupational Safety and Health), it is to be presumed that heat transfer installations working with organic heat transfer
18、 fluids which comply with this standard fulfil the relevant health and safety requirements. This document has been prepared by DIN-Normenausschuss Heiz- und Raumlufttechnik (DIN Standards Committee for Heating and Ventilation), Working Committee NA 041-01-41 AA Wrmebertragungsanlagen. DIN 4754, Heat
19、 transfer installations working with organic heat transfer fluids consists of the following parts: Part 1: Safety requirements, test Part 2: Draught diverter Part 3: Level controller Part 1 of this standards series replaces DIN 4754:1994-09; Part 2 replaces DIN 32727:1981-02, withdrawn in 2007-09; a
20、nd Part 3 replaces DIN 32728:1982-02, withdrawn in 2007-09. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. DIN shall not be held responsible for identifying any or all such patent rights. In addition to the legal units of measure
21、ment, this standard also uses the unit “bar”. It should, however, be noted that according to the German law on units in metrology, the use of these units is not permitted in official or business communications within Germany. Conversion: Unit not permitted Unit permitted Conversion bar Pa 1 bar = 10
22、5Pa Amendments This standard differs from DIN 4754:1994-09 as follows: a) Subclause 4.4 “Heater setup” has been completely revised and brought in line with the relevant regulations and codes of practice; b) the standard has been editorially revised. Previous versions DIN 4754: 1974-10, 1980-01, 1990
23、-12, 1994-09 DIN 4754-1:2015-03 6 Introduction The content of this standard is in agreement with the specifications of the Pressure Equipment Directive (DGRL). The requirements stipulated in the Betriebssicherheitsverordnung (BetrSichV) (German Ordinance on Industrial Safety and Health) and the Wass
24、erhaushaltsgesetz (German Water Management Act) have also been taken into consideration in this standard. The diagrams in Annex A are only simplified representations of the basic circuitry; they are not recommendations for certain types of circuit. The project configuration and installation of heat
25、transfer installations with organic heat transfer fluids require special experience due to the high working temperature. These activities can only be carried out by firms with the requisite knowledge. Supplementary explanations pointing to the required technical expertise of the planning and impleme
26、nting specialist firms can be found in Annex E. The normal heat transfer installations proven in practice as well as the experience with them were considered when formulating this standard. All pressures not specifically identified in this standard are overpressures to the atmosphere. DIN 4754-1:201
27、5-03 7 1 Scope This standard applies for heat transfer installations in which organic heat transfer fluids are heated to temperatures below or above their initial boiling point at atmospheric pressure. It applies to heat consumers only in spaces where heat transfer fluid passes through them. This st
28、andard has the purpose of satisfying protection targets for the production and supply, in particular those specified in the Pressure Equipment Directive (DGRL). It also serves as an aid in the compliance with the specifications of the Betriebssicherheitsverordnung. 2 Normative references The followi
