Solar Exhaust Pipe Structure China

Does pipe-embedded structure transfer solar heat from southern façade to northern façade?

Pipe-embedded structure transfers solar heat in southern façade to northern façade. Heat transfer model of the system is validated against experimental results. Energy saving effect of the system in the five building climate zones of China.

Which type of heat pipe should be used for solar collectors?

On the other hand, to transfer the converted thermal energy timely and avoid overheating on the surface of solar collectors, a heat pipe which depends on liquid–vapor phase change heat transfer is an efficient choice , , , .

What is pipe-embedded structure?

It provides a basis for the research of pipe-embedded structure at the scale of building. An active pipe-embedded closed wall loop connecting the exterior walls of the north and south room has a significant potential to improve thermal comfort and decrease the energy consumption of air conditioning systems during the heating season.

Does solar-driven heat pipe have a low thermal resistance?

The experimental results showed that the solar-driven heat pipe with a filling ratio 20% had a lowest thermal resistance of 0.25 K/W when it was placed vertically at a solar power density of 17.5 W/cm 2. 4. We demonstrated that the fabricated solar-driven heat pipe could directly harvest solar irradiation for efficient hot water production.

Can a pipe-embedded external wall transfer heat?

To further check the feasibility of the system, the heat transfer of a pipe-embedded external wall and a conventional wall are compared, with the same configurations under typical weather conditions in five building climate zones of China.

Does pipe-embedded wall reduce heating load?

The energy consumption of the circulating pump is calculated and the obtained results show that this energy could be neglected. Therefore, the results obtained from simulation proved the effectiveness of pipe-embedded wall in reducing heating load. Besides, the pipe-embedded envelope can also improve indoor thermal comfort.
