Mechanical Solutions Inc. (MSI) has teamed with Lennox Industries Inc. (Lennox) to develop a low-Global Warming Potential (GWP) HVAC system featuring ultra-small centrifugal compression to meet DOE’s requirement for more efficient HVAC systems. The developed system will be in the 2- to 20-ton range. Based on MSI’s leading-edge research in ultra-small centrifugal compressors, and Lennox’s tradition of market-leading technology advancements, the team expects to do the following:
