The comment period started January 8 and ends March 7. BSR/ASHRAE Standard 150P was developed to provide a uniform method for evaluating the performance of cool storage systems in buildings or central plants, including chillers, storage medium, storage device or vessel, heat sink equipment or heat sink systems, and other auxiliary equipment.

According to Charles Dogan, chairman of the 150P committee, some cool storage systems have components that are tested by manufacturers while others have no factory-tested components. However, all systems need to be evaluated to determine if all components perform as expected when matched with an existing cooling load.

“The goal of the standard is to provide a means for owners to ensure cool storage systems meet their needs and to provide a uniform test method to prevent surprises for contractors and manufacturers of such systems,” he said.

The test method in the standard eliminates the need to develop a specific test procedure for each individual project, and instead includes a uniform method of testing, identification of test equipment for performing such tests, identification of data required, calculations to be used, and definitions and terminology. Drafts of ASHRAE’s proposed standards, guidelines, or addenda are available only during their related public review periods.
