The energy regulations generate several challenges that can be easily taken up with variable speed technology. Inverter compressors are the best way to obtain and exceed the energy standards with high part-load and seasonal efficiency while providing several other key benefits. On top of the advantages provided by the technology (precise cooling and humidity management, low start-up current, energy efficiency etc.), Danfoss inverter scrolls VZH have specific features that offer high value to the customers and end users. The new generation bring further part-load and seasonal efficiency gains. The introduction of IDV technology in all models means there is no longer need for high and low pressure compressor optimization, potentially halving inventory management requirements. IDVs and permanent magnet motors in inverter scroll compressors are the major contributors to these performance levels. Operating maps have been extended to address the need of best efficiency in more applications. Boost your packaged air conditioning units, rooftops, chillers with the Danfoss VZH range.
