his presentation describes the methods for defining and verifying annual electrical and water savings resulting from the installation of two ElectroCell systems. The systems examined in this presentation were applied to open loop condenser water systems. The savings were realized in reductions in cooling plant energy and tower make-up water.
The savings definition and verification methods are consistent with the guidelines and methods established by the International Performance Measurement and Verification Protocol (IPMVP) committee. The consolidation of the energy use data was consistent with the Air Conditioning Heating and Refrigeration Institute (AHRI) Integrated Part Load (IPLV) methods for categorizing chiller kW/ton data.
There are two ElectroCell system installations in this presentation which are located in Massachusetts. First installation at building 55 NYA examined is an EC4000 installed on a 3000-ton capacity chilled water plant. The second installation examined at building 70 NYA, an EC6000 installed on a 4000-to capacity chilled water plant.
