Description

Technical Field

[0001] This utility model relates to the field of building-related technology, specifically a green building energy-saving ventilation structure. Background Technology

[0002] Green building is a building type that maximizes resource conservation (energy, land, water, materials), protects the environment, and reduces pollution throughout its entire lifecycle, from planning and design to construction, operation, and demolition, while providing users with healthy, efficient, and comfortable spaces. After construction, to ensure a good indoor environment, ventilation structures are needed to guarantee air circulation, maintain fresh air, lower indoor temperatures, and reduce humidity. Ventilation structures are generally divided into natural ventilation and mechanical ventilation. Natural ventilation utilizes the density difference between the air inside and outside the building or natural wind to create airflow. Mechanical ventilation uses mechanical devices to exhaust or supply air. However, existing ventilation structures, when using ventilation ducts for air exchange, cause significant fluctuations in indoor temperature due to changes in outdoor temperature, affecting the cooling or heating efficiency of the indoor air conditioning system and increasing its energy consumption. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a green building energy-saving ventilation structure.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a green building energy-saving ventilation structure, comprising a heat exchange ventilation pipe formed by connecting several heat exchange sub-tubes end to end. Each heat exchange sub-tube includes an air inlet inner tube and an air outlet outer tube, with an exhaust cavity formed between the air inlet inner tube and the air outlet outer tube. End plates are provided at the outer ends of the heat exchange sub-tubes at both the beginning and end.

[0006] The outer side of one end of the first-end ventilation duct is provided with an exhaust vent that communicates with the exhaust cavity, and the exhaust vent is located on the lower side of the ventilation duct; the outer side of the other end of the tail-end ventilation duct is provided with an exhaust inlet that communicates with the exhaust cavity, and the exhaust inlet is located on the upper side of the ventilation duct; the interior of the air inlet duct is provided with a guide plate that guides the airflow in the air inlet duct to both sides.

[0007] As a preferred technical solution of this utility model, the guide plate includes a central block fixed in the inner cavity of the air inlet pipe, and the central block is provided with an arched windward surface. The central block is provided with a guide vane on its periphery, and a ventilation gap is formed between the guide vane and the air inlet pipe.

[0008] As a preferred technical solution of this utility model, a docking sealing mechanism is provided between adjacent heat exchange sub-tubes;

[0009] The docking sealing mechanism includes a connecting pipe disposed at one end of the air inlet pipe and inserted into the air inlet pipe to which it docks. The outer side of the connecting pipe is provided with a boss that abuts against the end of the air inlet pipe to which it docks, and the boss is provided with a first rubber sealing layer for sealing the connection between the end of the air inlet pipe and the boss.

[0010] The connecting ends of the ventilation ducts are all equipped with flanges, which are fixed together by bolts, and rubber sealing rings are provided between the flanges.

[0011] As a preferred embodiment of this utility model, the air inlet inner tube is made of a heat-conducting material.

[0012] As a preferred technical solution of this utility model, the end of the connecting pipe is provided with a guide pipe with a size smaller than the inner diameter of the air inlet pipe.

[0013] As a preferred embodiment of this utility model, a second rubber sealing layer is also provided on the outer wall of the connecting pipe.

[0014] The beneficial effects of this utility model are:

[0015] 1. This green building energy-saving ventilation structure features an external ventilation duct installed outside the inner air inlet duct, forming an exhaust cavity between them. Fresh air is introduced into the room through the inner air inlet duct, while stale air is exhausted to the outside through the exhaust cavity.

Furthermore, the inner air inlet duct is equipped with guide vanes that direct the airflow to both sides, ensuring full contact between the fresh air and the inner wall of the inner air inlet duct, thus maximizing the heat exchange area.

[0016] 2. This green building energy-saving ventilation structure has a docking sealing mechanism between adjacent heat exchange sub-tubes. The air inlet inner tubes are connected by a boss that abuts against the port of the air inlet inner tube and are sealed by the action of the first rubber sealing layer, thereby ensuring a good sealing effect at the connection of the air inlet inner tubes after docking. The docking ends of the ventilation outer tubes are all equipped with flanges, and the flanges that dock with each other are fixed by bolts. A rubber sealing ring is provided between the flanges, thus fixing the ventilation outer tubes and sealing them by the action of the rubber sealing ring.

[0017] 3. This type of green building energy-saving ventilation structure has a guide pipe at the end of the connecting pipe with a size smaller than the inner diameter of the air inlet pipe, which makes it easy to insert the connecting pipe into the air inlet pipe and facilitates assembly.

Furthermore, the air inlet inner pipe 3 is provided with a guide plate 8 inside to guide the airflow in the air inlet inner pipe 3 to both sides, so that the fresh air can fully contact the inner wall of the air inlet inner pipe 3, thus providing a good heat exchange area.

By setting the ventilation duct 4 outside the air inlet duct 3, an exhaust cavity is formed between the air inlet duct 3 and the ventilation duct 4. Fresh air is introduced into the room through the air inlet duct 3, while the old air in the room is discharged to the outside through the exhaust cavity. During this process, the old air and fresh air in the room exchange heat under the action of the air inlet duct 3, thus reusing the heat of the waste gas and reducing the energy consumption of the air conditioning system.

[0027] In this utility model, the air inlet inner pipe 3 and the ventilation outer pipe 4 are fixed together by a bracket, and a fan for conveying gas is installed inside the air inlet inner pipe 3.

[0028] The guide plate 8 includes a central block 9 fixed in the inner cavity of the air inlet pipe 3, and the central block 9 is provided with an arched windward surface 10. The central block 9 is provided with guide vanes 11 on its periphery. A ventilation gap is formed between the guide vanes 11 and the air inlet pipe 3, so that the fresh air can fully contact the inner wall of the air inlet pipe 3, thereby having a better heat exchange area.

[0029] Among them, a docking sealing mechanism is provided between adjacent heat exchange sub-tubes 1;

[0030] The docking sealing mechanism includes a connecting pipe 12 disposed at one end of the inner air inlet pipe 3 and inserted into the inner air inlet pipe 3 to which it docks. A boss 13 is provided on the outer side of the connecting pipe 12 to abut against the end of the inner air inlet pipe 3. The boss 13 is formed by connecting the connecting pipe 12 to the port of the inner air inlet pipe 3.

The connecting ends of the ventilation outer pipes are provided with flanges 15, and the flanges 15 are fixed together by bolts. A rubber sealing ring 16 is provided between the flanges 15, thus fixing the ventilation outer pipes 4 together and sealing them by the rubber sealing ring 16.

[0031] The air inlet duct 3 is made of a heat-conducting material, which allows for better heat exchange between the fresh air and the old indoor air.

[0032] The end of the connecting pipe 12 is provided with a guide pipe 18 whose size is smaller than the inner diameter of the air inlet pipe 3, which makes it convenient for the connecting pipe 12 to be inserted into the air inlet pipe 3 and facilitates assembly.

[0033] The outer wall of the connecting pipe 12 is also provided with a second rubber sealing layer 17, which makes the connection of the air inlet pipe 3 have a better sealing effect.

[0034] Working principle: This green building energy-saving ventilation structure sets up an external ventilation pipe 4 outside the inner air inlet pipe 3, forming an exhaust cavity between the inner air inlet pipe 3 and the external ventilation pipe 4. Fresh air is introduced into the room through the inner air inlet pipe 3, while stale air is discharged to the outside through the exhaust cavity. During this process, the stale air and fresh air exchange heat under the action of the inner air inlet pipe 3, thus reusing the heat of the waste gas and reducing the energy consumption of the air conditioning system. The structure of the external ventilation pipe 4 encasing the internal ventilation pipe 4 provides a large heat exchange area, resulting in a better heat exchange effect. Furthermore, the inner air inlet pipe 3 is equipped with a guide plate 8 that directs the airflow to both sides, ensuring full contact between the fresh air and the inner wall of the inner air inlet pipe 3, thus providing a good heat exchange area.
