A single commenter requested that EPA involve R-454A as an acceptable refrigerant for ice skating rinks with out a two hundred-pound demand size limit, in alignment Using the proposal's listing for IPR and cold storage warehouses. The commenter also claimed that EPA did not offer adequate explanation why R-454A was unacceptable On this conclude-use or why EPA didn't to carry on which has a submitted SNAP petition to uncover R-454A appropriate.
A lot of SNAP listings include “remarks” or “additional data” to provide supplemental info on substitutes. Considering that this extra data is not Portion of the regulatory conclusion below SNAP, these statements usually are not binding to be used from the substitute under the SNAP system. Having said that, statutory and regulatory requirements so listed are binding underneath other authorities ( e.g.,
EPA's comprehension is always that, In combination with the technological constraints for refrigerant in chillers for IPR, There's two more situations where by usage of refrigerants is probably going for being more constrained, and thus, extra refrigerant alternatives that reduce In general threat to human wellness and the natural environment can be useful. The 1st of People circumstances is where by ASHRAE fifteen-2022 identifies a refrigerating program as aquiring a “superior likelihood” that leaked refrigerant from the failed connection, seal, or element could enter an occupied region. UL 60335-two-89 correctly sets cost limits for A2L refrigerants to 260 instances the LFL for applications inside of an occupied Room where by men and women could possibly be located. This total is about 200 kilos, with regards to the LFL of The actual refrigerant. In contrast, greater demand dimensions in gear Assembly the necessities of ASHRAE fifteen can be used in “lower-chance” destinations in which most people is not likely to return in contact with the refrigerant, like techniques Utilized in industrial occupancies, outdoors, or in the equipment home with obtain restricted to facility staff. In which most people is unlikely to come back into connection with any leaked refrigerant, there could well be much less House constraints and higher versatility in tools layout, so refrigeration system designers can accommodate a narrower list of refrigerants.
The restrictions with the SNAP program are promulgated at 40 CFR portion eighty two, subpart G, as well as Company's process for examining SNAP submissions is described in laws at 40 CFR 82.one hundred eighty. Less than these guidelines, the Company has discovered 5 types of listing decisions: acceptable; acceptable subject to make use of circumstances; satisfactory topic to narrowed use limitations; unacceptable; and pending (40 CFR 82.180(b)). Use conditions and narrowed use restrictions are both thought of “use limits.” Substitutes which have been considered appropriate without having use constraints (no use disorders or narrowed use restrictions) may be used for all apps inside the suitable conclusion-works by using while in the sector. Soon after reviewing a substitute, the Agency may perhaps ascertain that a substitute is suitable only if certain disorders in how that the substitute is used are achieved to minimize hazards to human health as well as the ecosystem.

there isn't any use situations pertaining to refrigerant demand capacity or distinct purposes inside stand-on your own models. In summary, While using the updates finalized for your use problems for stand-by yourself models, the typical use ailments are: restricting the usage of Each individual refrigerant to new gear that is definitely specifically made and Evidently marked for that refrigerant; use in line with ASHRAE 15-2022 and with UL 60335-two-89 (with certain exceptions), which includes screening, demand sizes, ventilation, usage Room necessities, and certain hazard warnings and markings; and needs for warning labels and markings on devices to tell consumers, specialists, and 1st responders of probable flammability dangers. EPA is finalizing the use circumstances On this action, which implement to new stand-by yourself models on or once the effective date of this last rule. This ultimate rule isn't going to implement to nor have an impact on machines manufactured before the efficient date of this action. The final regulatory text presents these various needs as numbered listings in independent table rows, in which the tip-use along with the productive time frame during which the gear is produced are while in the still left-most commercial freezers column, Together with the heading “Conclusion-use”; the precise demands are shown as use situations inside the fourth column, Using the heading “Use Circumstances.” Under SNAP, EPA sights products for being produced at the day on which the equipment's refrigerant circuit is finish, the appliance can perform, the equipment retains a complete refrigerant charge, as well as equipment is ready to be used for its meant reasons.
Revising the existing use circumstances for R-290 for use in new self-contained commercial ice devices;
One commenter supported listing R-454A as satisfactory in chilly storage warehouses but proposed that EPA not finalize a charge measurement Restrict use ailment of lower than 200 lbs for three motives. Initially, the commenter mentioned that R-454A is the next potential and more effective alternative than choices with GWPs of below one hundred fifty. They mentioned that specified the massive Power needs of cold storage warehouses, Strength effectiveness is often a significant aspect of these methods. 2nd, the commenter claimed that lots of of those programs are in industrial occupancies, refrigeration rooms, or machinery rooms and not restricted towards the charge limitations, listing, and installation specifications defined by UL 60335-2-89.
