Description

Technical Field

[0001] The invention relates to the field of indoor temperature regulation, and in particular to an indoor temperature regulation system of a solar wall coupled with an underground pipe. Background Art

[0002] Building energy conservation has become a hot topic of concern to all sectors of society. Countries around the world have begun to advocate the use of clean energy. In buildings, wall energy conservation is an important part of making a positive contribution to building energy conservation. The solar wall is a permeable solar heating system with air as the medium. It has been widely used at home and abroad as a pollution-free, active technology. It provides a feasible way to utilize directional heat flow in buildings. However, traditional solar walls have the problem of absorbing too much heat during the day in summer and dissipating heat quickly at night in winter, which causes the indoor temperature to change too quickly and affects comfort.

[0003] Geothermal energy has attracted much attention as an emerging clean energy source, and the resulting buried pipe system has been gradually promoted. The buried pipe system, also known as the ground-to-air exchanger, buries the pipes underground and uses the principle of heat exchange between air and soil to heat up or cool down the air in the pipes. It has a simple structure and low cost. However, the buried pipe system requires a continuous power system for air circulation, and relying solely on the buried pipe system is not enough to meet the indoor thermal comfort requirements.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The purpose of regulating indoor temperature is achieved by making maximum use of the heat collection effect of the solar wall and the constant temperature characteristics of the buried pipe. By setting an adjustable louver device, the outer side of the louver grille is made of reflective material and the inner side is made of thermal insulation material.

The solar wall system and the buried pipe system are coupled, and the solar wall system is used as traction to provide power for the air flow of the buried pipe, driving the overall air circulation. In summer, the wind extraction effect of the solar wall and the cooling effect of the buried pipe are used to cool the room. In winter, the heat collection effect of the solar wall and the geothermal exchange of the buried pipe are used to heat the room. The system can work continuously on sunny and cloudy days, with significant effects, thereby reducing the use of air conditioning, saving resources, and having broad application prospects.

[0018] The grille of the adjustable shutter device (2) of the present invention is made of reflective material on the outside and heat-insulating material on the inside, so as to effectively alleviate the problem of excessive heat absorption during the day in summer and rapid heat dissipation at night in winter when the solar wall is closed.

[0019] The upper 2 / 3 of the solar wall panel (3) of the present invention is arranged vertically, and the lower 1 / 3 is arranged inwardly inclined. The connection and the bottom are provided with a porous web C-shaped steel (13) for support, so that the air entering the air layer can fully contact the solar wall panel to be heated.

[0020] The buried pipe (9) of the present invention adopts four PVC pipes with a diameter of 120 mm and a rectangular cross-section, which are buried 3 m underground. The horizontal distance of the pipes is 200 mm, the vertical distance is 100 mm, the length of the pipe is 25 m, the inlet section is set to be inclined at 45° with the horizontal direction, and a slope of 2% is set to prevent condensed water from flowing back.

[0021] The indoor temperature regulation method of the present invention comprises the following steps: relying on the solar wall ventilation and heat collection system to supply heat to the room or provide air circulation power and the underground pipe system to cool down or heat up through geothermal exchange, and the two systems are coupled to work: during the daytime in winter, the third air valve (6c) is opened, the fourth air valve (6d) is selectively opened, the seventh air valve (12b) is opened, the adjustable shutter (2) is opened, and the other inlets and outlets are closed; the solar wall panel (3) is heated by solar radiation, and the air is heated to flow upward, and the outdoor cold air is heated once through the underground pipe (9), and the solar wall panel (3) enters the room after being heated twice. Similarly, the indoor cold air enters the system through the fourth air valve (6d) and is heated again, thereby forming an indoor circulation and replenishing the indoor hot air. At night, only the sixth air valve (12a) is opened, the other inlets and outlets are closed, the shutter (2) is closed, and the shutter grille forms a second insulation layer to block the entry of cold air and prevent the indoor heat from being lost; the outdoor cold air is heated through the underground pipe (9), and is mechanically drawn by the fan (10) and transported to the room to maintain the indoor temperature at night. During the daytime in summer, the first, second, third and fifth air valves (6a) (6b) (6c) (6e) are opened, the sixth air valve (12a) is opened, and the remaining inlets and outlets are closed; the lower side 8 / 9 of the louver (2) is closed, and the upper side 1 / 9 is opened, so that a reflective layer is formed on the outer side of the louver grille. The gas in the air layer is heated up quickly by the dual effects of solar radiation and louver reflection, forming a thermal pressure force, and the indoor hot air is pulled out through the upper air outlet; the outdoor hot air is cooled through the buried pipe (9) and transported to the room through the fan (10) to cool the room. In the evening, the solar radiation decreases, and the outdoor temperature gradually decreases, but is higher than the indoor temperature. The first, second and third air valves (6a)(6b)(6c) are opened, the sixth air valve (12a) is opened, and the other inlets and outlets are closed; the shutter (2) is closed, and a heat insulation layer is formed inside the shutter grille to prevent the indoor and outdoor air from exchanging heat. The air cooled by the buried pipe (9) is transported to the room through the fan (10). Due to the effect of air pressure, the indoor hot air is discharged through the upwind vent. At night, the outdoor temperature is lower than the indoor temperature. The north window is opened for natural ventilation and cooling, and the first, fourth and fifth air valves (6a)(6d)(6e) are opened, and the other inlets and outlets are closed; the shutter (2) is opened, and due to the effect of air pressure, the air enters the system and quickly takes away the internal heat to maintain a comfortable indoor temperature.
