retrofit equipment: 

• Chillers 

• Cold storage warehouses 

• Commercial comfort air conditioning 

• Commercial ice machines 

• Heat transfer 

• Household refrigerators and freezers 

• Ice skating rinks 

• Industrial process refrigeration systems 

• Industrial process air conditioning 

• Refrigerated transport 

• Retail food refrigeration 

• Residential de-humidifiers 

• Residential and light commercial air conditioning and heat pumps 

• Vending machines 

• Water coolers

refrigeration, is R-449A proposed for use in rack systems, condensing units, 

or stand-alone units? Please see Table 1 as a potential template for providing 

your response. 

• Retail food refrigeration (direct rack systems, indirect rack systems, 

other remote condensing unit systems, stand-alone units) 

• Refrigerated transport (containers, refrigerated trailers/vans, shipholds) 

• Industrial process refrigeration (petroleum processing, chemical 

production, food product manufacturing) 

• Chillers (by use—commercial buildings, industrial, etc.—and by type 

of compressor--centrifugal, reciprocating, screw and scroll) 

2. Charge Size. In Part III, Section D, Part (a) of the SNAP submission, you provide 

information regarding average charge sizes of commercial refrigeration units, which 

is one of the proposed end-uses for this substitute. 

Please provide average and maximum charge sizes for each anticipated end-use, 

as listed below in Table 1:
