RECOVERY STORAGE AND CONVERSION OF WASTE HEAT FROM AN ICE RINK USING A CONCENTRIC BOREHOLE HEAT EXCHANGER SYSTEM

摘要

This energy management system is designed to be controlled by a microprocessor unit to recover and transfer waste heat from an ice arena to a concentric borehole heat exchanger storage unit for transferring on demand to a heat pump for transfer to a district energy system or a single demand application. The heat pump may also convert the heat energy to cold energy to be transferred to demand points. A heat dissipation unit is available in the system to purge excess heat energy to maintain system thermal stability. The system also enables cold energy from an underground concentric borehole heat exchanger to be pumped directly to the arena or be pumped via a heat pump to a district energy system. In addition, the system may scavenge heat or cold from inside or outside the energy management system to transfer to demand points or borehole energy storage.
