Description

Technical Field

[0001] The utility model specifically relates to a building energy-saving breathing glass curtain wall, belonging to the technical field of glass curtain walls. Background Art

[0002] The breathing glass curtain wall has a ventilation function. In summer, the double-layer glass curtain wall uses solar radiation heating to generate thermal pressure, and reduces the temperature of the air interlayer through natural ventilation. In winter, by closing the air inlet and outlet, a greenhouse effect is generated to improve the thermal insulation effect of the building. The existing breathing glass curtain wall, such as the Chinese patent publication number: CN114876102A, discloses a double-layer breathing energy-saving glass curtain wall, including a curtain wall frame, an outer glass curtain wall and an inner glass curtain wall. The structure can make water flow circulate in the air buffer cavity in the form of a waterfall. At this time, the hot air in the air buffer cavity will exchange heat with the cold water, thereby reducing the temperature in the air buffer cavity, which can not only improve the thermal insulation effect of the glass curtain wall and reduce the energy consumption of indoor air conditioning, but the glass curtain wall with this structure cannot perform the breathing ventilation function well, and it is easy to cause waste of indoor heat or cold sources. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes a building energy-saving breathing glass curtain wall, which can realize indoor ventilation and partially recover indoor energy during breathing ventilation.

[0004] The utility model of energy-saving breathing glass curtain wall for buildings comprises a curtain wall frame, on which an outer curtain wall glass and an inner curtain wall glass are arranged; a hollow breathing layer is arranged between the outer curtain wall glass and the inner curtain wall glass; the outer curtain wall glass adopts tempered laminated glass (12+2.28PVB+12, all ultra-white), and the inner curtain wall glass adopts double-silver LOW-E tempered vacuum laminated glass (6+12A+6+1.52PVB+6, all ultra-white); the curtain wall frame comprises:

[0005] A profile frame, wherein the top and bottom of the inner side of the profile frame are provided with adjustment grooves facing the hollow breathing layer; a cylinder is fixedly engaged with one end of the adjustment groove away from the hollow breathing layer, and a sealing plate is fixed to the telescopic end of the cylinder; a pressing edge is arranged between the adjustment groove and the hollow breathing layer; a plurality of exhaust ports connected to the outside are provided at the upper adjustment groove; a plurality of air inlets connected to the outside are provided at the lower adjustment groove; an outer edge cover is integrally formed at the exhaust port and the air inlet on the outside of the profile frame; a filter body is fixed at the bottom of the outer edge cover;

[0006] Exhaust air module. The exhaust air module includes a first air pipe fitted to the top of the curtain wall frame and communicating with the hollow breathing layer. The first air pipe is connected to a three-way valve through a blower. The other two ends of the three-way valve are respectively connected with a second air pipe and a third air pipe. The second air pipe communicates with the upper adjusting groove, and the third air pipe is connected to the air inlet end of the air conditioning system through a filter.

[0007] Intake air module. The intake air module includes a notch fixed to the bottom of the curtain wall frame and communicating with the hollow breathing layer. A net plate is fixed in the notch. A pressing plate is attached to the outside of the net plate. Opposite sides of the net plate and the pressing plate are fitted and fixed with electromagnets that attract each other. Multiple telescopic rods are fixed on the net plate, and the telescopic ends of the telescopic rods are fixed to the pressing plate.

[0008] In summer, the three-way valve is closed. At the same time, the sealing plate and the pressing edge are separated. At this time, the exhaust port and the intake port are communicated. Under the irradiation of sunlight, the air temperature in the hollow breathing layer rises and naturally floats upward, forming an air flow from bottom to top. The heat in the hollow breathing layer is taken away by the chimney effect, thereby reducing the temperature of the inner curtain wall glass. It can reduce the consumption of indoor cold sources. When indoor air breathing and ventilation are required, the electromagnet acts to separate the net plate and the pressing plate, and two sets of cylinders act. The intake port and the exhaust port are closed. At this time, the blower discharges the indoor air to the outside through the blower, the three-way valve, the second air pipe and the adjusting groove. Then, the three-way valve is switched, the intake port is opened, and the outside air enters the air inlet end of the air conditioning system through the intake port, the hollow breathing layer, the blower, the three-way valve and the third air pipe. After the ventilation is completed, the blower and the three-way valve are closed, and the cylinders retract to restore the communication between the exhaust port and the intake port again.

[0009] In winter, the three-way valve is closed. At the same time, the cylinders expand and contract, and the sealing plate and the pressing edge are pressed together. At this time, the exhaust port and the intake port are closed. Under the irradiation of sunlight, the greenhouse effect is generated inside the hollow breathing layer, improving the heat preservation effect of the glass curtain wall and reducing the consumption of indoor heat sources.

[0010] Next, indoor internal circulation of breathing and ventilation is carried out. The electromagnet acts to separate the net plate and the pressing plate. At this time, the induced draft fan draws the indoor air through the induced draft fan, the three-way valve, and the third air pipe into the air intake end of the air conditioning system, so that the radiant heat inside the hollow breathing layer can be recovered and reheated by the air conditioning system for reuse indoors. After multiple internal circulation breathing and ventilations, an outdoor circulation breathing and ventilation is carried out. Immediately after the last indoor circulation breathing and ventilation, an outdoor circulation breathing and ventilation is carried out to avoid heat waste inside the hollow breathing layer. The three-way valve switches, and the induced draft fan discharges the indoor air to the outside through the induced draft fan, the three-way valve, the second air pipe, the adjustment slot, and the exhaust port. Then, the three-way valve switches, the air intake port opens, and the external air enters the air intake end of the air conditioning system through the air intake port, the hollow breathing layer, the induced draft fan, the three-way valve, and the third air pipe. After the ventilation is completed, the induced draft fan and the three-way valve are closed, and the cylinder extends to restore the closed state of the exhaust port and the air intake port again.

[0011] Further, an internal phase change heat exchanger is fixed at the bottom of the hollow breathing layer, and the side of the internal phase change heat exchanger is communicated with the notch; a perforation communicated with the air intake port is also provided on the internal phase change heat exchanger. When the indoor air carrying heat or cold sources is introduced into the hollow breathing layer by the induced draft fan and the air passes through the internal phase change heat exchanger, the energy is absorbed by the internal phase change heat exchanger. The air that has completed energy absorption re-enters the room or is discharged to the outside. When the external air passes through the internal phase change heat exchanger, the internal phase change heat exchanger loads the energy onto the fresh air and enters the air intake end of the air conditioning system along with the fresh air, realizing energy recovery and breathing and ventilation.

[0012] Further, an external phase change heat exchanger is installed at the output end of the induced draft fan of the first air pipe; a plurality of through holes communicated with the three-way valve are provided on the external phase change heat exchanger. During operation, when the air carrying heat or cold sources is drawn by the induced draft fan and sent to the external phase change heat exchanger, after the energy is recovered by the external phase change heat exchanger, the air enters the second air pipe or the third air pipe through the three-way valve, realizing the discharge of the dirty air to the outside or re-entering the indoor internal circulation. When the external air passes through the external phase change heat exchanger, the external phase change heat exchanger loads the absorbed energy onto the fresh air and enters the air intake end of the air conditioning system along with the fresh air, realizing energy recovery and breathing and ventilation.

[0013] Further, a rubber plate is fixed on one side of the sealing plate close to the pressing edge, and the rubber plate is pressed tightly against the pressing edge.

[0014] Further, a plurality of sliding rods are movably fitted at one end of the adjustment slot away from the hollow breathing layer, and the sliding rods are fixed to the sealing plate. During operation, when the telescopic end of the cylinder drives the sealing plate to act, the sealing plate presses tightly against the pressing edge to close the adjustment slot. During the action, the sealing plate is guided by the sliding rods so that the sealing plate can move linearly up and down.

[0015] Compared with the prior art, the building energy-saving breathing glass curtain wall of the present utility model can perform breathing ventilation on indoor air, and during the breathing ventilation, partial recovery of indoor energy can be achieved. Moreover, in winter, the solar radiation heat inside the hollow breathing layer can be recovered and sent into the room, making it more energy-efficient. BRIEF DESCRIPTION OF THE DRAWINGS
