This presentation is a case study examining three unique central plant heat recovery chiller applications connected to three unique low-temperature hot water loops. The first is an example of new construction (plant, distribution, and connected load) based on a design temperature of 135F and multiple small heat recovery chillers. The second is a single large heat recovery chiller being installed in series with the existing main heat plant boilers connected to over 10M SQFT of existing buildings based on a design temperature of 170F. The third is the new installation of second-generation of heat recovery chillers in an existing plant supporting both existing and new construction with a design temperature ranging from 140 to 180F.
