How do design decisions made during the Design/Development phase impact overall chiller system efficiency? We will look at how chilled water and condenser water temperatures affect, not only chiller efficiency, but overall system efficiencies. We will expand on how variable speed chillers behave as temperature and flow rates vary. Additionally, the speaker will discuss how chillers and heat pumps can be successfully integrated into thermal storage and geothermal systems to assist in greatly exceeding the ASHRAE 189.1 High Performance Green Building Standard and the Minnesota SB 2030 Energy Standard. Finally, we will expound on how oil-free magnetic bearing VSD compressor technology is optimized around the new low-GWP refrigerant, HFO-1233zd.
