The compressor is specifically designed to run at different motor speeds to modulate cooling output.
Proper oil management is a critical requirement to ensure compressor lifetime.
Variable speed technology can be implemented in HVAC, close control and process cooling applications and as diverse as packaged or split air-conditioning units, rooftops, chillers, precision cooling, VRF and condensing units.
The inverter frequency drives need to use algorithms developed specifically for heating, ventilation and air conditioning (HVAC) or for refrigeration.
The drive can also manage other devices such as oil injection valves or multiple compressors.
