  Ice storage technology is a key energy-saving solution for modern buildings. By making ice during off-peak night hours (using lower electricity rates) and melting it for cooling during peak daytime, it significantly reduces air-conditioning operating costs. A critical component in this system? The   U-shaped stainless steel heat exchanger tubes   inside the storage tank—their design directly impacts efficiency, stability, and lifespan. Let’s break down this essential technology. How Ice Storage Units Work & the Tank’s Role An ice storage system consists of a refrigeration unit, ice storage tank, heat exchanger, and control system. Its core processes: • Nighttime ice-making: During low electricity demand, the refrigeration unit cools water or glycol in the tank below freezing, forming ice on the outer surface of heat exchanger tubes to store cold energy. • Daytime ice-melting for cooling: When demand peaks, hot return water is pumped into the tank. It exchanges heat ...
