Technical Field

The invention relates to the technical field of solar energy utilization, in particular to a passive heat transfer type solar house system based on an organic Rankine cycle technology.

Background

At present, the technology for building village and town houses in China is simple, scientificity is generally lacked, and even the most thermal performance and moisture-proof and corrosion-proof measures are ignored, so that the houses have poor heat insulation performance and low comfort level. In cold areas in winter, many rural residences still use distributed heating modes such as heated brick beds, fire walls and furnaces, and the heat efficiency is only about 15%; the traditional method is still adopted for the outer wall, the roof, the door and the window of the house, the heat insulation performance of the house maintenance structure is poor, and the heat transfer coefficients of the outer wall and the roof are respectively more than 50% larger than the energy-saving design standard of the building, so that the waste of heating energy consumption is serious.

Disclosure of Invention

The invention aims to more fully utilize solar energy resources and improve the heat preservation and heat insulation performance of rural house construction, provides a passive heat transfer type solar house system based on an organic Rankine cycle technology, has reasonable structural design, and utilizes the solar energy resources to realize the self-sufficiency of electricity utilization and heating of rural houses. The technical scheme adopted by the invention is as follows:

a passive heat transfer type solar house system based on an organic Rankine cycle technology is provided with three subsystems, namely a passive solar house system, an organic Rankine cycle power generation system and an electricity storage and voltage regulation discharge system.

And the passive solar house system is coupled with the organic Rankine cycle power generation system and provides a heat source for the organic Rankine cycle power generation system. And the electric quantity generated by the organic Rankine cycle power generation system is supplied to users for use. In order to avoid the waste of electric quantity in the using process, an electric storage and pressure-regulating discharge system is added between the organic Rankine cycle power generation system and a user.

Furthermore, the passive solar house system mainly comprises a normal-temperature air inlet, a hot air outlet, a built-in air flow channel, a solar energy absorption heat transfer material, a heat insulation material and a hot air transmission pipeline. The organic Rankine cycle power generation system mainly comprises: the heat exchanger, the expander, the condenser, the working medium pump and the generator. The power storage and voltage regulation discharging system mainly comprises power storage equipment and voltage regulation equipment.

Furthermore, the heat absorbing material is uniformly laid on the surface layers of the roof and the wall surface, and the air in the air flow channel is heated by absorbing the solar energy. And meanwhile, in order to avoid the over-high temperature in the room, heat insulation materials are paved between the air flow channel and the wall and the roof.

Further, in order to accelerate the air flow in the system, an air pump is arranged at the normal-temperature air inlet section.

And further, the heated air flows to a heat exchanger through a hot air transmission pipeline, and exchanges heat with a working medium of the organic Rankine cycle power generation system in the heat exchanger.

Further, the working medium of the organic Rankine cycle power generation system adopts R245fa, R123 or a mixture of R245fa and R123.

The hot air transmission pipeline exchanges heat with the heat exchanger and is discharged or is introduced into a room for heating according to the condition.

In addition, after the hot air exchanges heat with the working medium of the organic Rankine cycle power generation system, the hot air can also be used for heating a house according to the situation. Therefore, the self-sufficient heating and electricity-taking of the house is realized by fully utilizing the solar energy.

The invention has the advantages that: the solar house and the organic Rankine cycle are combined to form self-sufficient heating and electricity-taking of the house building. Meanwhile, an electricity storage and pressure regulation discharge system is additionally arranged between the organic Rankine cycle power generation system and a user, so that waste of high-grade energy is avoided.
