Healthcare engineers looking to decarbonise their facilities and considering – as part of this – ways to reduce the significant energy consumed by their HVAC system’s chillers now have an alternative to simply replacing them with more energy-efficient models, with ‘a leap forward in smart compressor control technology’ from Aermec.
The company says existing chillers can benefit from its ‘smart compressor technology’, which delivers ‘up to 50% energy savings’. It explained: “Aersave is a ground-breaking, easily retrofittable technology for scroll compressors; retrofitting it improves the chillers’ energy efficiency, delivering tangible savings.” Meanwhile Aersave is ‘a proven innovation that not only helps mitigate against rising energy costs, but also increases performance levels and the longevity of existing chillers, and helps Estates managers transition towards the Government’s Net Zero target.”
The Aersave ‘smart’ compressor controller converts any three-phase fixed speed compressor to a variable speed compressor. Aersave can be used on any manufacturers’ chillers, operates with any refrigerant, and is compatible with all brands of BMS systems. Aermec said: “By enabling compressors to work smarter, Aersave eases reliance on the electrical grid, increases reliability, offers compressor protection, and can easily be retrofitted by any air-conditioning or refrigerant engineer.” Claimed benefits include lower noise levels, precise room temperature and humidity control, and safeguarding compressors against short cycling, all ‘with no interference with existing controls’.
Aersave comprises two sensors instead of pressure transducers; one connects onto the suction line of the compressor, and the other to the discharge line. A ‘unique’ compressor control gathers the temperature from the two sensors’ points, and data via Modbus from the device via the compressor. These are then input to an algorithm, which calculates what speed and compressor capacity is required for the complete system to achieve its demand capacity.
While working on lower frequency for prolonged periods of time, an oil return sequence brings the oil back to the compressor to protect it.
Aermec explains that Aersave also has multiple dip switch settings that can be switched dependent on the whether the compressor types is reciprocating or scroll. It also controls the fan motor – whether a condenser or evaporator fan motor. As the technology can work with any type of refrigerant, there is no need to cut into the refrigerant line.
