announced today the expansion of its variable speed technology platform, integrating compressors, drives, and controllers for heating, cooling and refrigeration systems. This integrated solution ...

drives, and controls solutions are helping to meet energy-efficiency and capacity requirements, said John Schneider, president of HVACR technologies at Americas at Copeland. “Copeland will soon launch ...

The device that controls the fan speed is called a variable speed drive. Variable frequency drives are also used on pumps and cooling towers to match the demand of the space with the proper energy ...

The performance of the system was evaluated considering operating efficiency and stability and the scientists found that a device relying on a variable-speed compressor and an MPPT controller ...
