Description

Technical Field

[0001] This utility model relates to the field of ventilation and heating pipe technology, and more specifically, to an indoor ventilation and heating pipe for green buildings. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) is an integral part of green building. In academic classification, it stands for Heating, Gas Supply, Ventilation, and Air Conditioning Engineering, encompassing heating, ventilation, and air conditioning. Functionally, it is an indispensable part of future human life. HVAC ducts have a very wide range of applications, including supply and return air ducts for purification systems, central air conditioning ventilation ducts, industrial supply and exhaust ventilation ducts, environmental protection system air intake and exhaust ducts, mining gas extraction pipes, and mining coated fabric ventilation ducts, etc. Indoor ventilation in green buildings requires the use of HVAC ducts.

[0003] While existing technologies achieve indoor ventilation in green buildings through HVAC pipes, ordinary HVAC pipes perform poorly in terms of energy recovery. During ventilation, a large amount of cold or heat is lost from the room, increasing the energy consumption of the building's HVAC system, which does not conform to the concept of energy conservation in green buildings. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] An indoor ventilation and heating pipe for green buildings includes a pipe body, a connecting structure, an air purification structure, and an energy recovery structure.

A round hole is opened on the annular plate, and the first screw passes through the round hole and is connected to the first nut at both ends.

[0007] Furthermore, a sealing gasket is provided between the flange and the first groove.

[0008] Furthermore, the protective layer is sealed and fixed to the base layer with hot melt adhesive.

[0009] Furthermore, the air purification structure includes a telescopic locking post, a locking groove, a second screw, a second nut, and an adsorption net. The telescopic locking post is fixedly installed on the inner wall of the tube. The outer side of the adsorption net is provided with a locking groove. The side wall of the locking groove is provided with a first through hole. The telescopic locking post is provided with a second through hole. The telescopic locking post is installed in the locking groove. The second screw passes through the first through hole and the second through hole and extends out to connect with the second nut at both ends.

[0010] Furthermore, a sealing sponge is attached to the contact area between the adsorption mesh and the inner wall of the tube.

[0011] Furthermore, it also includes a filter screen, which is installed on the inner wall of the pipe near the pipe opening, with a sealing sponge attached to the contact area between the filter screen and the inner wall of the pipe.

[0012] Furthermore, the filter screen uses activated carbon.

[0013] Furthermore, it also includes guide vanes, which are fixedly installed on the inner wall of the tube and are made of high-strength, lightweight aluminum alloy material.

[0014] Furthermore, the guide vanes are twisted, with the twist angle gradually increasing from the inlet to the outlet along the ventilation direction.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In this utility model, such as Figure 2As shown, the guide vane 5 is welded to the inner wall of the pipe body 1. The guide vane 5 is made of high-strength, lightweight aluminum alloy, which has good corrosion resistance and can adapt to indoor humid or slightly corrosive gas environments, extending its service life. At the same time, the low density of aluminum alloy reduces the weight of the entire HVAC pipe, facilitating installation and transportation, while its strength is sufficient to withstand the impact force generated by airflow. The guide vane 5 is twisted, with its twist angle gradually increasing from the inlet to the outlet along the ventilation direction, starting at 15° and ending at 45°. The cross-section of the vane is streamlined; this design effectively reduces airflow resistance while enhancing air guidance, making it easier to form a spiral airflow.

The telescopic locking post 301 is welded to the inner wall of the tube body 1. The adsorption net 306 has a locking groove 302 on its outer side. The side wall of the locking groove 302 has a first through hole 303. The telescopic locking post 301 has a second through hole and is located inside the locking groove 302. The second screw 304 passes through the first through hole 303 and the second through hole and extends out to connect with the second nut 305 at both ends. A sealing sponge is pasted around the contact area between the adsorption net 306 and the inner wall of the tube body 1. A filter 307 is located on the inner wall of the tube body 1 near the opening. A sealing sponge is pasted around the contact area between the filter 307 and the inner wall of the tube body 1. The filter 307 is an activated carbon filter 307.

[0028] In this utility model, such as Figure 4 As shown, the energy recovery structure 4 includes a base layer 401 and a phase change material 403. The base layer 401 is wrapped in a ring around the outer wall of the tube body 1. The base layer 401 and the tube body 1 are tightly bonded together by a hot pressing process. A second groove 402 is opened on the surface of the base layer 401. The phase change material 403 is filled in the second groove 402. A protective layer is provided on the outer layer of the base layer 401. The protective layer and the base layer 401 are sealed and fixed by hot melt adhesive.
