Detailed ways

As shown in Figure 1-a, a multi-functional roof heating and ventilation device using solar energy includes an inclined roof 1, a light-transmitting surface 2 in the middle of the roof 1, and a sunshade and heat preservation curtain that can be opened or folded on the upper part of the roof 1. 3. The sunshade and heat preservation curtain 3 is wound on the drive shaft of the motor, and the opening or folding of the sunshade and heat preservation curtain 3 is realized by changing the direction of the motor. The floor 7 is arranged horizontally below, the roof 1, the rear outer wall 4 and the horizontal floor 7 form a triangular structure, a fan 8 is installed on one side of the floor 7, and there are air supply and exhaust outlets 9 below the fan 8, and the fan 8 and the air supply and exhaust There is a first air volume regulating valve 11 between the air outlets 9, and the air supply and exhaust air outlets 9 lead to the room at the lower end; on the other side of the floor 7, there are return and exhaust air outlets 10 and a second air volume regulating valve 15, and the indoor and return, The exhaust outlet 10 is connected, and the floor 7 between the return and exhaust outlet 10 and the supply and exhaust outlet 9 is fixed with a heat storage body 14 through a bracket 13. There is a heat insulating material 12 on the floor 7, and the heat insulating material 12 or injection In the floor material, or laid on the floor.

The first ventilation window 5 and the second ventilation window 6 are respectively located at the upper part and the lower part of the rear outer wall 4, the first ventilation window 5 has a smaller area, and the second ventilation window 6 has a larger area. The second ventilation window 6 is either a fixed structure or a rotatable structure to adapt to different seasons.

The blower fan 8, the first air volume regulating valve 11 and the air supply and exhaust outlets 9 form the air supply channel, and the return and exhaust air outlets 10 and the second air volume regulating valve 15 form the return air channel, and the air supply channel is located at the front side of the room , while the return air channel is located on the rear side of the room. The high end of the roof 1 is the rear side of the room, and the low end of the roof 1 is the front side of the room. The thermal accumulator 14 on the floor 7 is fixed on the floor 7 with a bracket 13 .

The working principle of the utility model is: during the daytime in winter (see Figure 1-a), the sunshade and thermal insulation curtain is rolled up, the first ventilation window on the upper part of the rear outer wall is opened and the second ventilation window on the lower part is closed. At this time, the fan and the two The two air volume control valves are all in the open state. As the glass roof receives a large amount of solar radiation, the air temperature rises. At the same time, under the action of the fan, a small airflow continuously enters the roof from the outside. The air and the indoor air are forced to circulate, so that the solar radiation energy can be fully utilized to heat the circulating air, and the room can be heated and ventilated.

At night in winter (see Figure 1-b), put down the sunshade insulation curtain to reduce heat loss from the roof and the room. The opening and closing states of other components are the same as during the day in winter, and the heat stored in the heat storage body during the day is used to heat the circulating air.

In summer (see Figure 1-c), put down the sunshade and thermal insulation curtains to prevent a large amount of outdoor heat from entering the roof, and open all the ventilation windows on the rear outer wall. The effect of pressure and air convection can achieve the effect of ventilation inside and outside the roof, which can ensure that the temperature of the solar roof will not be too high.

During the daytime in spring and autumn (see Figure 1-d), the sunshade and thermal insulation curtains are rolled up, and the ventilation windows on the rear outer wall are all opened. When a large amount of solar radiation is received, the temperature of the air rises, resulting in a strong thermal pressure effect. The indoor air flows into the roof through two air outlets, and finally exhausts to the outside through the ventilation windows.

At night in spring and autumn (see Figure 1-e), the opening and closing states of all components are the same as during the day in spring and autumn. Due to the large amount of heat dissipation from the heat storage body, the temperature of the air inside the roof rises, and the effect of thermal pressure is obvious. Two exhaust outlets flow into the roof, and finally exhaust to the outside through the ventilation windows.

The utility model can make full use of solar energy in different seasons or different time periods of the day to heat the room (mainly in winter) and ventilate (mainly in spring and autumn), and can be widely used in indoor areas with sufficient sunlight. Heating and ventilation occasions.
