This ENL will discuss several system designs that take advantage of heat pumps, including distributed water-source or ground-source heat pump systems, centralized geothermal heat pump systems, and configurations that make use of water-to-water heat pumps. It will include a brief discussion of variable-speed compressor technology and include content from the Trane application manual (SYS-APM010-EN) on WSHP/GSHP systems.

Presenters: John Murphy, Paul Solberg, Mick Schwedler
