COMPRESSORS
Aersave compressor technology off ers up to 50% savings, says Aermec
Approximately 59% of the electricity consumed by commercial buildings in the UK is used by lighting, IT, cooling and heating. Motor loads from chillers and AHUs are large energy consumers. Facilities managers and plant operators are constantly looking at cost eff ective solutions that can help to drive down dependencies on energy and with a preference for a retrofi t solution.
T
here are many ways to ensure optimal chiller effi ciencies. Specifying the correct unit size, operating parameters, using EC
fans, maintaining appropriate refrigerant levels to ensure the compressor’s effi ciency as well as regular service and maintenance and knowing when to replace and aged chiller can all help to drive down energy consumption and reduce emissions. Taking advantage of technological
innovations and factoring in the costs benefi ts can make economic sense and improve your equipment’s sustainability. One of the latest developments that can transform how chillers operate is a smart compressor technology from Aermec. Following successful trials, Aermec is launching Aersave, a technology for scroll compressors that can help protect customers from rising energy costs by improving the energy effi ciency of their chillers and delivering up to 50% energy savings. We all know that compressors on chillers
are large energy users. Reducing their energy consumption can typically be achieved by replacing them with a more energy effi cient system but Aersave can off er an alternative solution.

“Energy usage is one of our customers’ largest costs and concerns. Aersave can help businesses signifi cantly improve the energy effi ciency of their chillers by as much as 50% whilst increasing their lifespan and boosting their ROI,” says Paul Lawrence.
The Aersave smart compressor controller converts any 3-phase fi xed speed compressor to a variable speed compressor.
Aersave is a proven innovation that can help mitigate against rising energy costs whilst increasing performance levels, longevity of existing chillers and help customers transition towards the government’s net zero target. It is a signifi cant leap forward in chiller technology that enables compressor to work smarter. But how does it work? The Aersave smart
compressor controller converts any 3-phase fi xed speed compressor to a variable speed
compressor. A major benefi t is that Aersave can be used on any manufacturer’s chiller, using any refrigerant and it is compatible with all brands of BMS systems. According to Amerec, Aersave eases reliance on the electrical grid, increases reliability, off ers compressor protection, and can be easily retrofi tted by any air conditioning or refrigerant engineer.
The benefi ts are decreased noise levels,
precise room temperature and humidity control, the compressor is protected from short cycling and there is no interference with existing controls.
Operation
Aersave comprises two sensors instead of pressure transducers. One connects onto the suction line of the compressor, the other to the discharge line. Its unique compressor control gathers the
temperature from the two sensors’ points, together with gathering data via Modbus from the device via the compressor, which are then input to an algorithm, which calculates what speed and compressor capacity is required for the complete system to achieve its demand capacity.
