In today’s era of pursuing efficient and eco-friendly energy use, the choice of water source is crucial for scroll heat pump units , a key heating and cooling equipment. After comprehensive consideration and practical verification, groundwater is undoubtedly the most ideal water source for these units. Groundwater boasts stable temperature characteristics. Unlike surface water, which is greatly affected by seasons and climate, groundwater maintains a relatively constant temperature year-round. This is vital for the stable operation of scroll heat pumps. In winter, when surface water temperatures drop sharply, groundwater remains at a suitable level, providing a sufficient and steady heat source for the pump to ensure heating efficiency. In summer, when surface water becomes too warm for cooling, the lower temperature of groundwater helps the unit cool efficiently, reducing energy consumption and boosting overall operational performance.
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 ...
