MetadataShow full item record
This preliminary report contains the literature review, a preliminary description of the methodologies that have been chosen for the project and final site selection recommendations for ASHRAE Research Project RP 1004 ~ "Determining Long-term Performance of Cool Storage Systems From Short-term Tests".
DescriptionThe literature review covers the relevant literature concerning: (1) different inverse analysis methods, including: building simulation models, regression models, multicollinearity and function forms, (2) methods for predicting long-term performance from short-term measurements, (3) analytical models for chillers, fans and pumps, including a discussion of component-based models versus overall systems models, (4) in-situ testing of chillers, fans and pumps, (5) methods for determining the long-term performance of cool storage systems, including field performance testing, methods for determining annual load frequency distribution, characterization of cool storage system performance, and annual performance projections, and (6) methods for determining the uncertainty associated with measurement and analysis, including: measurement uncertainty, bias and random errors, propagation errors, and regression errors. A preliminary description of the methodologies is included that describes the methods that have been chosen from the literature to perform an in-situ analysis of pumps, HVAC systems, chillers and cool storage facilities. Information for 14 cool storage sites is also presented including recommendations for 3 sites which have been selected for further study. This report completes Task la (Literature Review), and Task lb (Preliminary Report), and presents our recommendations for approaching Task 2a (Method to estimate long-term building loads from short-term data), Task 2b (Development of analytical methods for Thermal Energy Storage Systems - TES), Task 2c (Development of initial list of TES sites and submit to PMSC), Task 3c (Uncertainty analysis), and Task 3d (Development of long-term TES performance methodology).
