CH-89-19-4 (RP482) -- Field Measurement of Chilled Water Storage Thermal Performance PDF

This project investigated the performance in a systems context, of several types of chilled water storage systems in commercial buildings. The study included eight storage systems of four different designs located in the United States and Canada. Water volumetric flow rates and tank inlet and outlet temperatures were measured during tank charging and discharging cycles to calculate the charge and discharge cooling capacity. Storage effectiveness was evaluated for each charging and discharging cycle for several cycles per site. Comparisons are drawn among the various systems tested based on thermal performance and observations on cold storage system operation in the field.
