In the automotive industry, various tests and analyses for using R-1234yf have been performed. The results show the overall risk to be higher than when using R-134a, but they also show no relevant general increase in risk in the event of an accident. In Japan, R-1234yf has been used in enclosure cooling units and other cooling systems for many years now. As Rittal has been supplying units containing R-1234yf to the Japanese market since 2018, it has gathered a lot of experience with this substance. Machine manufacturers can therefore use Rittal cooling units and chillers in enclosures and other applications for the foreseeable future without having to make any major changes. This means they can sell their equipment worldwide and remain in compliance with the relevant regulations. Thanks to UL and IEC certifications, the very low volumes of A2L used, and a safety optimised design, these Rittal units can be used anywhere in the world without any need for additional safety measures. CREATING PLANNING CERTAINTY Rittal offers its customers a complete, future-proof portfolio that covers all applications. The cooling unit and chiller technology delivers a sustainable, energyefficient and viable solution for the long term – one that extends well beyond mere transitional technology. For special cases in which operators document an unacceptable risk in their application, Blue e units with the refrigerant R-513A (GWP 631) continue to be available. From 1 January 2027, cooling units with a cooling output of up to 12 kW must use refrigerants that meet this GWP limit. DID YOU KNOW? GWP-based reduction in the available volume of HFC refrigerant from 2015 to 2050. For further information: www.rittal.ie Does R-513A still have a role in certain applications? R-1234yf will not suit every installation, particularly in situations where site-specific safety requirements would prevent the use of an A2L refrigerant R-513A has an A1 classification, providing lower toxicity and no flame propagation under standard test conditions, but its GWP is around 631. For projects in the Republic of Ireland, its use in new equipment needs to be assessed against the applicable EU restrictions. Where site-specific safety requirements prevent the use of a lower-GWP alternative, an exemption may be available, subject to the relevant regulatory conditions and supporting documentation. We have a portfolio of cooling products that use R-513A for sites where flammability is not permitted. However, any panel builders or system integrators who are relying on this exemption will need proof that the installation meets regulatory conditions. Customers will need to provide a site-specific risk assessment to clarify why the safety requirements at an operating site would prevent the use of a lower-GWP alternative. A refrigerant decision that extends beyond GWP R-290, or propane, offers another route towards very low-GWP cooling and carries a lower GWP than R-1234yf. However, it its A3 classification means manufacturers must account for its higher flammability when designing their cooling units. Of itself, that flammability does not necessarily make R-290 an unsuitable refrigerant, but the unit’s design does need to be factored in within the context of the operating site. Our choice of R-1234yf is based on its combination of very low GWP and A2L classification, which reduce the need to treat refrigerant selection as an isolated environmental calculation or regulatory restriction. Instead, customers can simply focus on how the complete cooling unit would manage the thermal demands required by the project, understanding that the energy demands for our cooling units has also been optimised.
