WebChart #1is to be used for A, B and C type loops. Chart #2gives the total length of the expansion joint (L) along the outer surface. Example: Given a 200 foot run of 1-3/8” medium temp piping; there will be a linear expansion of 3” to compensate for (medium temp 1.5” per 100 feet). Pipe diameter has no affect on the amount of linear WebSep 24, 2024 · A major difference between A2L and A1 refrigerants is their tank colors. Traditionally, R-22 comes in teal / green cylinders, while R-410A comes in pink cylinders. A2L refrigerants come in silver cylinders with a red stripe; you must fully evacuate these and puncture them with a non-sparking pick for disposal.
WebJun 16, 2024 · In the United States, ozone-depleting substances (ODS) are regulated as class I or class II controlled substances. Class I substances, such as chlorofluorocarbons (CFCs) and halons, have a higher ozone depletion potential and have been phased out in the U.S.; with a few exceptions, this means no one can produce or import class I substances.
