JOAP: SANHUA - R290 Propane Catalogue - 2020

90 sanhuaeurope.com Product Line Series The Sanhua R32 Product Line Series belongs to a new group of products developed for the next generation refrigerants. The European Regulation EU No. 517/2014 on fluorinated greenhouse gases (F-Gas Regulation) imposes a clear plan to gradually reduce the use and the impact of HFCs with high GWP. The final goal is to reduce dramatically the quotes in the market of the refrigerants with GWP above 2500 (first step) and the ones with GWP above 150 (second and final step). In some critical applications like domestic refrigerators and freezers the prohibition of HFC with GWP > 150 started from the 1st of January 2015. Many other applications see as deadline for the use of high GWP HFCs the 1st of January 2020 or the 1st of January 2022. In Air Conditioning (A/C) application the extensive use of the R410A, a refrigerant with a GWP equal to 2088, in few years will have to stop introducing alternative refrigerants with a GWP lower than 700. A good substitute for R410A is R32, a high- density refrigerant with a GWP limited to 675. In comparison to the R410A the refrigerant R32 imposes a slightly higher working pressure, so all the Sanhua R32 Product Line Series have an enhanced Design Pressure (PS) of 49bar. The refrigerant R32 is classified as A2L (lightly flammable refrigerant) according to ASHRAE STANDARD 34-2016 and EN 378-1:2016 Annex E. R32 also belongs to Group 1 which includes substances and mixtures, as defined in points 7 and 8 of Article 2 of EC Regulation No 1272/2008, that are classified as hazardous in accordance with physical or health hazard classes as laid down in Parts 2 and 3 of Annex I to that Regulation. A list of 18 classes of hazardous fluids is included in point 1.a of Article 13 (explosive, flammable, oxidizing, toxic). According to the PED Directive 2014/68/EU (Art.4.1 and ANNEX II), in case of usage with fluids Group 1, the valves with Nominal Diameter > 25mm belong to Category II and they must satisfy the essential safety requirements set out in Annex I. All these models (Cat.II) are covered by a third part certification issued by a recognized European notify body. The complete Sanhua R32 product line series can also be used with HFC refrigerants (A1 ref.), classified in Group 2 according to EC Regulation No 1272/2008. All the electromechanical valves present in the Sanhua R32 Product Line Series ensure a protection against the electric shock respecting the appropriate mounting described in the installation manual. Each valve and coil respect, where applicable, the prescription of the EU Directive 2014-35-EU (Low Voltage Directive). An additional third part certification issued by VDE institute guarantees the respect of the prescriptions indicated in the LVD and in the standards listed below, ensuring a safety usage of the product in systems operating with flammable refrigerants (A2L ref.) and (A3 ref.): EN 60335-2-24; EN 60335-2-24 Subclause 22.110. EN 60335-2-89; EN 60335-2-89 Subclause 22.109. EN 60335-2-40; EN 60335-2-40 + A11:2004 + A12:2005 + A1:2006 + A2:2009 + A13:2012 +A13:2012/AC:2013 subclause 22.116 (no electrical component, which could be a source of ignition in case of normal operation or in the event of a leak); subclause 22.117 (Annex BB). Most of the products especially designed for R32 applications can guarantee enhanced working limits. Besides the Design Pressure increased to 49bar, in many cases the maximum allowed refrigerant temperature is equal or above 150°C. This limit permits a reliable installation also on the discharge line in R32 system without liquid injection circuit.
