AN-92-14-3 -- Integrating an Off-Peak Cooling System with a Fire Suppression System in an Existing High-Rise Office Building

In certain jurisdictions, fire suppression systems require a fire water storage (sometimes called auxiliary water storage) tank to supplement the normal source of water to the fire pumps. They are most prevalent in areas where a natural catastrophe such as earthquake may interrupt the normal supply. Off-peak cooling systems have numerous technologies, yet all require some form of storage tank or tanks. By combining the two systems such that they utilise a common storage reservoir, it is possible to save on first costs and help to motivate building owners to install off-peak cooling systems. Deals with the obstacles to and benefits of accomplishing such a project and the several years of work and testing required to satisfy all parties involved. Tests were carried out using an encapsulated ice storage system using an inhibited 18% concentration of potassium chloride additive for antifreeze protection.
