One commenter asked for that EPA involve R-454A as a suitable refrigerant for ice skating rinks with no two hundred-pound cost sizing Restrict, in alignment With all the proposal's listing for IPR and chilly storage warehouses. The commenter also claimed that EPA did not deliver enough explanation why R-454A was unacceptable With this stop-use or why EPA didn't to move forward with a submitted SNAP petition to find R-454A suitable.
Using a plethora of alternatives offered, we recognize that choosing the best commercial freezer might seem daunting.
If your kitchen is persistently heat and busy, this option may very well be suitable. Positioned nearer to the floor, it Advantages from cooler air and provides a slight elevation to lessen racks, building them simply accessible.
to be used in refrigeration units with massive demand sizes inside a equipment area or outdoor. Below the present SNAP listings, new stand-alone units applying R-290 happen to be topic to your use problem to fulfill the requirements of Appendix SB in the tenth edition of UL 471. Within this remaining motion, stand-by itself models using R-290 produced ahead of the powerful date may proceed to be used beneath SNAP and can remain in compliance with the existing SNAP use circumstances as long as they fulfill the applicable use problems whenever they had been manufactured. New stand-by yourself units using R-290 created in the helpful date of this final rule by September 29, 2024, should fulfill the necessities of either Appendix SB with the 10th edition of UL 471 or UL 60335-2-89, dependent on which typical they ended up Accredited, to comply with the use disorders proven With this closing motion.
Also, it's crucial to on a regular basis keep an eye on and file the temperature to ensure it stays in the suitable assortment.
Supplemental use disorders precise to particular finish-works by using might also apply and are reviewed with Each and every closing listing. The regulatory text of the ultimate listings, such as the final use circumstances and even more facts, appears in tables at the conclusion of this document.
ASHRAE 15-2022 is going through constant routine maintenance with publication of periodic addenda and is typically updated and republished each individual three yrs. Even though there have been added variations to ASHRAE fifteen-2022 in between issuance from the proposed rule and now, EPA was unable to overview and seek touch upon use circumstances determined by People More moderen alterations soon after publication in the proposal.
Moreover, the stated substitutes have lower GWPs than most other obtainable solutions for a similar utilizes. The shown refrigerants may perhaps offer further decreased-GWP selections for situations exactly where other refrigerants with decrease GWPs are certainly not practical, such as scenarios the place sparks or flame could occur this sort of that HCs are certainly not appropriate for use, or for systems with remote compressors or tools necessitating more substantial demand dimensions, commercial freezers where refrigerant leaks usually tend to build increased flammability risk.
When thinking about distinctive doorway selections, both equally solid and transparent glass versions have their positive aspects.
commercial ice product makers. In response to opinions associated with the fee of kit for a lot of the listed refrigerants, EPA notes this rule doesn't demand the usage of any precise refrigerant; alternatively, this rule establishes requirements that permit to the Risk-free use with the stated refrigerants, such that they don't pose overall greater risk to human well being and also the surroundings. Comment:
Two commenters suggested that permitting R-454A would easy the transition to minimal-GWP refrigerants in stand-by yourself models, enabling the sector to satisfy timing aims with the Technological know-how Transitions Rule. A different commenter urged EPA to list R-454A for use in self-contained equipment. The third commenter mentioned that the amount Utilized in self-contained products is a lot less than that Employed in distant gear, thereby decreasing the potential risk of any destructive results.
The next scenario where usage of refrigerants is probably going for being much more constrained, and therefore exactly where EPA is listing R-454A, is for use in the high-temperature facet of cascade devices used for non-chiller IPR machines (and Along with the refrigerant temperature getting into the evaporator larger than −30 °C). As discussed in portion II.A.one of this preamble, “Background on retail food items refrigeration,” both sides of a cascade system takes advantage of a unique refrigerant that is certainly most suitable for the supplied temperature selection. Greater temperature systems, or maybe the “large-temperature facet,” have commonly employed HFCs to be a refrigerant; even so, it is technologically achievable and has grown to be more widespread to use ammonia while in the substantial-temperature facet.
