HVACR in 2017

Joe Sanchez, engineering manager, Bitzer US Inc., said three major trends are occurring in the HVAC arena: a desire for low-GWP (global warming potential) solutions, a call for higher energy efficiency, and a desire for ease of use. Compressors are a part of all three.

“Low-GWP refrigerants are an industry-wide trend now, driven by worldwide legislation. Highly efficient performance is driven not only by the U.S. Department of Energy (DOE), but also by building owners looking for a better return on investment,” Sanchez said. “To obtain higher efficiency, variable-frequency drives [VFDs] are now routinely employed, which adds an additional level of complexity for the OEMs and contractors. In addition to this challenge, the industry is entering an age of ‘big data’ and needs to effortlessly connect, collect, and transfer information.”

To meet these demands, Bitzer launched a number of new products under the IQ platform. According to Sanchez, these intelligent compressors include integrated VFDs.

The compressors in the IQ line are designed for ease of use and service. The inverter in the new CSV compact screw compressor is refrigerant-cooled and requires no fans. And, by using Bitzer’s BEST software, a compressor can be setup with just a handful of parameters instead of hundreds, Sanchez said. In addition, the compressors are designed with built-in communication capabilities designed to make them simple for building owners to retrieve data related to the compressor and system.

“Finally, the CSV compact screw compressor, like nearly the entire Bitzer product line, is already approved for low-GWP refrigerants, such as hydrofluoroolefins [HFOs] and HFO blends,” Sanchez added.
