A chiller unit utilising a scroll compressor is set to generate 15% lower energy consumption than models with a traditional compressor design.
The unit has been produced by air conditioning manufacturer Rhoss, using an ABB standard drive.
Scroll compressors pressurise the refrigerant between two interleaved spirals or scrolls, resulting in a design with fewer moving parts, less noise and reduced vibrations compared to other compressor types. Variation of output is traditionally provided by mechanical means, for instance by splitting the cooling capacity of the chiller into several circuits. However, by using the ABB standard drive, Rhoss has achieved better performance while using a simple design with a single circuit.
