Compressor specialist Bitzer recently showcased one of its most important innovations for 2014 in Milan, exhibiting a new CSVW2 study.
The CSVW2 technology study has been specially designed for use with water-cooled liquid chillers in installations with low condensing temperatures.
Its mechanism is based on the tried-and-tested CSVH2 compact screw compressor, combining proven strengths with new capabilities at low load conditions.
In order to achieve a high COP and ESEER for this application, Bitzer has integrated some innovative drive technology. This is particularly important in chillers using water-cooled condensers.
The CSVW2 study pulls off this trick by devising a new permanent magnet motor, which delivers better efficiency at low speeds and low loads than the CSVH series. As a consequence, Bitzer has even modified the frequency inverter.
Unlike the CSVH2 compressor, the CSVW2 has been optimised for water-cooled rather than air-cooled chillers.
The CSVW2 study also features automatic operating parameter control and a performance range, which can be reduced by up to 16 per cent. The CSVW2 study is the same size and weight as the compact CSVH2 range.
Thus, the CSVW2 will not only set new efficiency benchmarks for its class but also offer the lowest weight and most compact dimensions.
