Analysis and research of building temperature difference transfer heat recovery systems

Energy conservation is a global concern. In addition to utilizing renewable energy, recovering internal building energy is also an important energy conservation measure. This paper proposes a heat recovery system designed to transfer temperature differences, facilitating the movement of thermal energy from southern to northern regions or between internal and external zones of buildings. The system can be integrated with conventional cold and heat source systems. Application calculations and economic analyses show that the investment required for this system is manageable, yielding significant energy conservation for applicable buildings or locations, thereby contributing positively to both energy conservation and emission reduction.
