hello good afternoon friends, I wanted to know what pressure and amperage is wearing 3 caps with a compressor (1/3 high) of 134a and r12?

Good evening, and the omorma colleague I clarify very well the point related to the pressures of work for these two types of refrigerant, however, you must take into account that the working pressures of a team do not have to do at all with the its size, if it is 2 caps, 3 caps, etc; the amount of refrigerant (in grams or ounces) if they differ, smaller equipment will require less refrigerant than larger equipment, but the working pressures are similar for the same type of refrigerant, the compressor amperage depends on the design of the same , they usually have on their label certain data such as the LRA, the RLA, the FLA that have to do with the consumption of the compressor, the compressors of 1/3 hp in freezer usually have a consumption of 3 to 4 amps in 110 V, but they must be compressors for low, not for high, if you place a high compressor in a freezer that should be for low temperature, it will not perform the same and you can damage the compressor, since the high one is designed to handle a density determined refrigerant, and the volumetric displacement of the high compressor is less than a low compressor, therefore, I recommend you install a low compressor instead of a high compressor.
