Description
The Amana-Goodman 0163L00012 Variable Pitch Sheave VL40 is an essential part of the HVAC equipment, and its purpose is to change the rate of the compressor motor. This sheave has a variable pitch design to enable the control of the rotational speed of the compressor as required. Since the diameter of sheave is changed, the belt tension and therefore the speed of the compressor is changed. This dynamic adjustment has several essential advantages. Firstly, it raises the system efficiency since the compressor can run at the optimum speeds relative to the prevailing cooling or heating needs. This means that the parts use least energy and hence cut down the running of electrical part.
