How to Take the Spin Out of Variable Frequency Drive Compressors

How to Take the Spin Out of Variable Frequency Drive Compressors

Variable frequency drive compressors, or variable-speed drive compressors, have gained popularity as energy prices have risen. These compressors power air-flow systems, matching supply to demand rather than operating at one particular frequency or speed. However, critics such as Chris E. Beals, writing for PlantServices.com, suggest a certain amount of marketing and sales "spin" is responsible for these compressors' growing market share. You should be certain that you truly need this type of compressor before making a purchase

Instructions

1
Measure the actual air capacity of your system, rather than the percentage of capacity. The more you run your system near 100 percent power, the less the efficiency data favors the variable-speed compressor over a fixed-speed compressor.

2
Determine if you need only one compressor, or multiple compressors in your system. Energy savings percentages in sales literature will only apply if you are using the variable frequency compressor alone -- if you have two or more compressors, you will either need to change them all over, or expect reduced savings.Dreambox DM8000

3
Conduct an independent energy analysis. Companies intent on selling a certain type of compressor may offer to conduct one themselves, but they have a vested interest in a particular result and may not be unbiased
