How a compressor responds to partial demand determines much of its energy use, and the two main methods differ clearly.
Load/Unload Control
The compressor runs fully loaded or idles, wasting some energy during the unloaded time.
Variable Speed Control
The motor slows to match output to demand, saving the most energy when the load varies widely.
Choosing the Better Option
Steady loads suit load/unload with storage, while fluctuating loads favour variable speed machines.
