Variable speed

About inverter technology for AC, heating and ventilation

A quantum leap in energy efficiency
The HVAC market is rapidly changing. Inverter technology is the most energy efficient technology and is currently revolutionizing the way air conditioning systems are being designed and built to meet climate control needs around the world. The first to embrace variable-speed technology gains a competitive advantage.

Market needs: Avoid system oversizing, reduce electricity bill and inrush current, increased comfort and process are some key drivers for variable capacity.

Modulating technologies: There are several ways to modulate the cooling capacity in refrigeration or air conditioning and heating systems.

ByPass method

Working principle: Inverter compressors operate at different speeds generating a modulated refrigerant mass oil flow and cooling output.
