Abstract

Heat pump systems and radiant floor heating systems are extensively employed to adjust indoor temperatures. Both types of system can reduce energy consumption and increase the coefficient of performance, with some limitations, to further improve energy conservation and environmental protection. For this reason, the development of an environmentally friendly and energy-saving system that is suitable for future energy demands is necessary. A new space heating system coupled with an underground energy storage system, without the use of heat pumps, is proposed herein. To validate the practicality and feasibility of the methodology established in this study, many simulations were performed, and sensitivity analyses of possible influencing factors were conducted. The modeling results proved that human indoor space heating demands can be satisfied with almost zero carbon emissions using the system proposed in this study.
