Night-storage underfloor cooling systems

摘要

An underfloor cooling system for cooling a building structure has tubing located in or under a massive floor of the structure for circulating water through the system. The water is directed through a cooling means connected to the tubing to cool the water. The cool water is then returned to the tubing to cool the massive floor and passively cool the structure. The cooling means may be a direct evaporative cooler or an evaporative radiative roof spray system. The cooling means may be located outdoors. The system may additionally include active cooling delivery such as at least one fan coil or at least one hydronic panel, through which cool water from the underfloor tubing is circulated to provide cool air to the structure.
