Giải thích
Refrigerant recovery cylinders are color-coded with a gray body and a yellow top or shoulder so they are easy to distinguish from virgin refrigerant cylinders. Solid colors such as green (older R-22), orange (R-404A), and light blue (R-134a) identify specific virgin refrigerants, not recovered mixtures. The gray and yellow scheme signals that the contents may be a mix that must be reclaimed or reused properly.
