HVACR compressor manufacturers strive to deliver high levels of reliability, comfort, and efficiency in a market that also demands low cost and compliance with environmental laws. But now, more than ever, they are faced with an even stronger charge to provide compressors that offer an optimum level of efficiency while maintaining reliability and comfort.
The latest legislation, regulations, and end user preferences have contributed to that charge, creating tough demands with regard to energy efficiency and comfort. Compressor manufacturers have been making sure these challenges are faced head on by continuously delivering cutting-edge improvements in compression technology.
MODULATING TECHNOLOGY: A BALANCING ACT
Today’s conventional, fixed-capacity compressors have a lot to offer, but because full compressor capacity is not always needed, units with conventional compressors run intermittently, to reduce output under light load conditions. This can cause discomfort from temperature swings and poor humidity control, as well as decreases in efficiency and overall reliability. As a result, manufacturers have worked to develop technologies that specifically meet part-load challenges and provide higher efficiency, improved comfort, and better system performance.
