[Bldg-sim] Swimming Pools

[JRR]

Hi Jim;

Several Timeshare vacation condos with athletic facilities & pool have 
Tranter ?? brand heat pumps that are specially
designed to reduce humidity in the pool space and reclaim that heat for 
the rest of the building.........
Massanutten resort near Harrisonburg VA has a large Tranter..........
