Chris Micallef, the CEO of Falkonair, joins Nathan Orr at AHR to discuss energy savings for three-phase equipment. They also explore some of Falkonair\u2019s controls for compressors, especially on DC inverter equipment.

Falkonair has software that allows users to control all types and brands of three-phase compressors with compatible variable frequency drives (VFDs). The software recommends the compatible VFD based on the amperage readings. Falkonair aims to bring this software to the refrigeration industry and then move on to HVAC contractors and data centers.

The control unit adjusts the compressor speed to respond to changes in refrigerant charge levels (based on discharge temperature). These controls protect the compressor and maintain efficiency, even under less than ideal operating conditions. Energy efficiency can increase by 35% with Falkonair\u2019s control units in place. You can expect longer runtimes, a reduction in short cycles, and a reduction in humidity.

If the refrigerant loss is too great, then the control can also shut down the compressor. However, it should take less time for a facility manager to notice that refrigerant loss is happening. The controls use temperature probes, so they don\u2019t cut into the refrigeration circuit.

Although VFDs are good for reducing vibrational wear and tear, we have to be aware of potential issues with harmonics. Harmonics can damage the bearings, especially on pumps that don\u2019t have oil constantly lubricating the bearings.

Chris and Nathan also discuss:

• VFD sizing considerations
• How Falkonair\u2019s AI works with hot gas bypass\xa0
• Software commissioning
• Oil return sequences on DC inverter systems
• Hertz ranges and limitations per compressor type
• How Falkonair\u2019s control units can exceed 35% efficiency gains
