THERMAL STORAGE STRUCTURE OF UNDERFLOOR

摘要

PROBLEM TO BE SOLVED: To quickly and smoothly form a thermal storage layer of an underfloor space of a house. SOLUTION: Fluid routes for passing a heating medium or a refrigerant are arranged in upper and lower layers, which can be switched and operated. This is similar in the case of utilizing an electric heater. A fluid route and an electric heater may be combined in upper and lower layers of two layers. A heating/cooling means may be sometimes arranged in a concrete foundation of a building together with such a thermal storage structure.
