The AE compressors are used for household refrigerators, freezers, dehumidifiers, vending machines, and water coolers (see Fig. 9-12). They are made in 1/20, 1/12, 1/8, 1/6-, 1/5, and 1/4 hp units. The oil charge may be 10, 16, 20, or 23 oz. This AE compressor model line uses R-134a, or an acceptable substitute, and, in some cases, R-22 as a refrigerant. The older models still in use may have R-12 refrigerant. When servicing older equipment it is best to remember some of the older charges.
