Emerson Introduces Copeland™ Commercial HVACR Variable Frequency Drives for Refrigeration ST. LOUIS, May 25, 2021 – Emerson (NYSE: EMR) announced the introduction of its Copeland commercial HVACR variable frequency drives (VFDs). They are specifically engineered to save energy in a variety of demanding commercial and industrial refrigeration applications. Adding a VFD to control the speed of a compressor, evaporator or condenser fan in applications such as a refrigeration rack or chiller can enhance overall system reliability and provide significant energy reductions, delivering quick return on investment (ROI) for users in this space. When applying Copeland commercial HVACR VFDs to equipment, the same work gets done using less energy: 15 to 30 percent energy savings can be achieved compared to running a fixed-speed compressor or general duty motor. When a drive is applied to a fan or pump, the motor speed for those applications can be modulated from 10 to 100 percent. The efficiency from using a VFD is a result of better load matching, reducing the number of start/stop events and pulling down loads faster, which eliminates unnecessary energy consumption. “With variable frequency drive technology, the end user typically experiences improved temperature and humidity control, reduced noise, and adaptable capacity for changing loads and weather conditions,” said Joe Summers, senior product manager — scroll & drives for Emerson. “Improved reliability is also achieved through proactive motor failure prevention, advanced diagnostics, decreased susceptibility to power instability and by greatly reducing the number of start/stop events.”
