Chennai, Tamil Nadu, Danfoss Industries Private Limited, a leader in mechanical and electronic components and solutions, today announced the launch of the first R-410A variable speed scroll compressors for commercial air conditioning and heat pumps: the Apexx™ VSH series compressors. Compared to conventional systems, these compressors allow for users to realize energy savings of more than 20 percent.

While compressors in traditional commercial system designs are sized for most efficient operation under peak load conditions, these compressors are able to deliver excess capacity under the part-load conditions that exist 85 percent or more of the time without the unloading capability. The penalty is significant and costly energy waste. In contrast, the Danfoss VSD compressor is designed to maintain high isentropic efficiency at part load by precisely and continuously matching the load by operating from 30 Hz to 90 Hz. The balanced, continuous operation of a VSD compressor means less cycling and system stress resulting in higher reliability, and longer lifetime.

With Apexx™ VSH compressors, the power factor remains above 0.90, regardless of the load, and can result in lower utility charges. Also, drive controller logic ensures a soft start that reduces inrush current and adds to energy savings. The VSH compressors also offer greater comfort as a result of tighter temperature control and the ability to cool or heat rapidly on demand by instantly increasing speed.

Creating a quieter environment is another competitive difference for the VSD. There is significant noise reduction, particularly at part-load conditions. For instance, noise reduction is especially critical at night and in densely populated areas - therefore, during the night, when loads are typically lowest, a VSD compressor cycle runs at its lowest and quietest speed. The Danfoss Apexx™ VSH compressors offer a gamut of advantages, such as, an all new degree of control capability, varied capacity, built-in reliability, user-definable closed-loop PID capacity controller, innovative pack controller for hybrid units and much more.
