Commercial Cool Storage Design Guide PDF

PREFACE

Cool storage - a technique for shifting all or part of the air conditioning requirements from peak to off-peak hours - offers the potential to reduce peak electricity demands and generate significant savings in electric bills. Several hundred cool storage installations already exist in the United States and Canada. The technology is particularly attractive to utilities in summer-peaking areas, where it can help control demand growth and improve the use of available generating capacity. A number of these utilities now offer special rates, incentives, and other programs designed to promote cool storage in their service territories.

One obstacle to greater acceptance has been the lack of information about system alternatives and design procedures. It is the purpose of this handbook to provide comprehensive guidance for designing ice and chilled-water storage systems for commercial buildings.

The guide contains or references state-of-the-art information necessary to evaluate the costeffectiveness of cool storage options; select, configure, and screen system alternatives; and carry out heating, ventilating, and air conditioning (HVAC) system design incorporating cool storage.

Both chilled-water and ice storage systems are described, including techniques and design data for feasibility analysis, cost-effective system sizing and operation, design of storage tanks, selection of refrigeration components, design of water and air distribution systems, and equipment maintenance. Deviations from conventional HVAC design and common design errors are also discussed. Two case studies illustrate successful cool storage applications, and a final section lists information sources, such as manufacturers, trade organizations, and R & D institutions.
