Variable-Speed vs Single-Speed: Which Is Best for My ,

Like we mentioned, variable-speed technology can refer to 2 different motors in the AC: The blower motor, which is responsible for blowing air through your home's ductwork The compressor, which pumps refrigerant (the liquid/gas that absorbs heat from your home's air) throughout the AC system

When to Choose Variable Speed Drive or Fixed Speed Air ,

Because the fixed speed compressor has a lower capacity (because it is the lower HP unit) than the variable speed drive compressor, the fixed speed unit will run at 100 percent capacity allowing the VSD to reduce RPM and trim

Applying Variable Speed Compressors in Multiple ,

With the variable speed compressor as the base-load and the fixed speed compressor as the trim-load compressor, the facility is spending 20% more in energy than a system with one 150 hp variable speed compressor, one 75 hp fixed speed compressor, one 150 hp fixed speed compressor, and a master controller
