DX techniques), and since some IPR applications need temperatures under −thirty °C, EPA is listing both of these supplemental refrigerants to provide extra reduced-GWP selections that pose lower Total hazard to human wellness plus the atmosphere than other offered substances and to deal with a broader variety of apparatus and apps. EPA is also finalizing a use situation for R-454A that enables its use in chillers for IPR or in IPR devices Using the refrigerant temperature getting into the evaporator is a lot less than or equivalent to −thirty °C, in addition to other specific other apps, as explained During this section. Furthermore, EPA is listing HFC-32, R-454A, and R-454B as satisfactory, subject matter to employ conditions, for chillers due to specialized restrictions, for instance volumetric ability, functioning tension, and temperature range, which limit the specialized viability of some other Harmless and environmentally suited Start off Printed Webpage 50436 options for many apps. The Agency previously stated these 3 refrigerants as satisfactory, subject to implement problems, in centrifugal and good displacement chillers for comfort cooling in SNAP Rule twenty five due to the same complex considerations and with the similar use situations as EPA is finalizing below.
EPA agrees Together with the opinions concerning the incomplete and incorrect statement that the smallest forms of retail food items refrigeration utilize either brazen or welded refrigerant circuits.

Two commenters proposed alterations for the proposal to align with existing standards to the IPR sector. A single commenter stated that very substantial programs located in industrial occupancies, refrigeration rooms, or machinery rooms never slide under the listing nor installation necessities of UL 60335-2-89. An additional commenter noted that suppliers adhere to ASHRAE 15, American Society of Mechanical Engineers (ASME) b31.
