VFDs for residential systems.

Summary

This article is the Fifth in a Five-part series on variable frequency drives (VFDs). Variable-speed operation of the compressor and indoor air blower is one way to provide energy-efficient capacity modulation. This takes advantage of the speed cubed power law, as discussed in previous columns in this series. Compressors and blowers are typically designed for worst-case operating scenarios. Residential cooling loads vary greatly. Therefore, by operating systems at levels that vary below design maximum, significant energy and cost savings can be achieved.
