Energy Efficiency

The APR Control provides alternative design strategies that have been proven to reduce total power consumption of a new or existing system installation/design. By modulating the DX compressor for load-matching performance, the APR Control helps save energy via direct compressor power savings and allowing for total system optimization in many applications.

Optimize Energy Efficiency with APR Control

The concept of Optimization has become prevalent in the HVAC industry. It is an agreed upon term that refers to controlling the HVAC systems to provide the necessary amount of cooling to maintain building comfort demands at energy efficient levels to utilize the least amount of power consumption.
