February 24, 2014 - Designed for small rooftop and process cooling applications, VZH inverter scroll compressors deliver precise cooling capabilities between 4 and 6.5TR with one compressor or up to 13 tons with manifold configuration. Permanent magnet motor and Intermediate Discharge Valves (IDVs) promote part-load efficiency. Facilitating efficiency ratings up to 21 IEER, compressors can modulate from 15–100 RPS.

Press release date: February 13, 2014

The company announces extension of compressor range, showcases high part-load efficiency manifold configurations during the 2014 AHR Expo

NEW YORK CITY – During the 2014 AHR Expo®, Danfoss, the global leader in commercial compressors, announced it will extend its inverter scroll compressor range VZH in 2014 to include three new models. The variable speed VZH compressors provide superior efficiency at part-load conditions, can improve efficiency by more than 30 percent compared to fixed-speed compressors, and offer precise cooling capabilities.

Designed for small rooftop and process cooling applications, the new inverter scroll compressor range VZH will introduce cooling capacities between 4 and 6.5TR with a single compressor, and up to 13 tons with a manifold configuration. With a permanent magnet motor and patented Danfoss Intermediate Discharge Valves (IDV), which can help improve part-load efficiency by up to 24 percent, the new variable speed compressor range VZH will facilitate efficiency ratings up to 21 IEER and can modulate from 15 to 100 RPS.

Additionally, a pre-qualified package, including the Danfoss inverter scroll compressor VZH and drive optimized to work together, is fully integrated to save time in unit development, ensure a more reliable solution to improve product time to market, and enhance overall system efficiency.

The first VZH models were released in December 2012, ranging from 13 to 26TR and suitable for chiller and large rooftop applications.

Manifold compressors offer higher part-load efficiency

To improve reliability and part-load efficiency of large chillers and rooftop units with manifold compressors, Danfoss designed its 40-ton scroll compressors and SH large compressors to be capable of retaining oil in non-operating compressors under part-load operation. This design reduces the risk of failure due to poor lubrication, and improves heat transfer in the evaporator – boosting overall system efficiency.

Compressors in manifold configurations also improve uptime, and reduce costs and sound levels.
