AH compressors

The AH compressors are designed for residential and commercial airconditioning and heat pump applications (see Fig. 9-17). They can be obtained with either three- or four-point mountings (see Fig. 9-18). The internal line-break motor protector is used. It is located precisely in the center of the heat sink position of the motor windings. Thus, it […]
