Description

Technical Field

[0001] This invention relates to the field of fresh air and heat exchange system technology, specifically to a fresh air and heat exchange energy-saving system. Background Technology

[0002] Currently, as users' quality of life improves, their demands for indoor air quality are also increasing. Typically, air filters are installed indoors, but these only filter out airborne particles and cannot replace carbon dioxide with fresh oxygen!

[0003] Therefore, there is an urgent need for a fresh air and heat exchange energy-saving system to address the technical problems described above. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technologies and provide an energy-saving fresh air and heat exchange system.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is a fresh air and heat exchange energy-saving system: including a first air duct, a second air duct, an air outlet duct, a fixed frame, a tubular heat exchanger, and a honeycomb heat exchanger. The fixed frame is provided with the first air duct, and a second air duct is provided on one side of the first air duct on the fixed frame. The upper ends of the first air duct and the upper ends of the second air duct are combined to form an end pipe. One end of the end pipe is connected to the tubular heat exchanger. An air outlet duct is provided at the upper end of the end pipe. One end of the air outlet duct is connected to the tubular heat exchanger. A honeycomb heat exchanger is provided inside the bottom end of the first air duct. A first air inlet is provided at the lower end of the first air duct, and a second air inlet is provided at the lower end of the second air duct.

[0006] The tubular heat exchanger includes an outer shell and V-shaped tubes. The V-shaped tubes are disposed inside the outer shell, and both ends of the V-shaped tubes are flush with both ends of the outer shell. The upper end of the V-shaped tubes is connected to the wall of the outer shell. A cavity is formed outside the V-shaped tubes inside the outer shell. An inlet and an outlet are respectively provided in the cavities below the V-shaped tubes at both ends of the outer shell. One end of the end tube is connected to the inlet.

[0007] The air outlet duct is equipped with an inner tube that is connected to the wall of the lower end of the air outlet duct. The lower end of the inner tube is connected to the end of the V-shaped tube adjacent to the inlet.

[0008] As an improvement, a rain cover is provided at the upper end of the air outlet duct.

[0009] The advantages of this invention compared to existing technologies are as follows: It includes a first duct and a second duct. The upper ends of the first and second ducts are combined to form an end pipe and connected to a tubular heat exchanger. One end of the outlet duct is connected to the tubular heat exchanger. A honeycomb heat exchanger is installed inside the bottom of the first duct, drawing fresh outdoor air into the room through the "chimney effect." Similarly, the "chimney effect" blows in fresh air, which, after passing through the honeycomb heat exchanger, increases the upward speed of the airflow, rushing upwards until it reaches the indoor exhaust duct outlet, where a "negative pressure" is created, carrying away polluted indoor gases.

[0010] The above explains the structure and principle of indoor and outdoor air exchange! This is one of the key shortcomings of household air conditioners!

[0011] Another major practical feature of this invention is that it completely changes the unchanging heat exchange (copper coil + heat sink + fan) structure! It adopts a "honeycomb heat exchange" structure! The heat exchange fluid no longer needs to go through repeated back-and-forth movements in the pipes!

[0012] The weight difference of using stainless steel profiles in honeycomb structures is simply unmatched! More importantly, the ventilation effect of honeycomb structures is many times faster than that of traditional copper coils! Liquid resistance is many times lower! Compressor power is reduced many times! Truly achieving: material savings; increased efficiency; and significantly reduced energy consumption! Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Combined with appendix Figure 1-6 A fresh air and heat exchange energy-saving system includes a first air duct 1, a second air duct 2, an air outlet duct 3, a mounting frame 4, a tubular heat exchanger, and a honeycomb heat exchanger 5. The mounting frame 4 is equipped with the first air duct 1, and the second air duct 2 is provided on one side of the first air duct 1 on the mounting frame 4. The upper ends of the first air duct 1 and the upper ends of the second air duct 2 are combined to form an end pipe 6. One end of the end pipe 6 is connected to the tubular heat exchanger, and the upper end of the end pipe 6 is equipped with an air outlet duct 3. One end of the air outlet duct 3 is connected to the tubular heat exchanger. The honeycomb heat exchanger 5 is provided inside the bottom end of the first air duct 1. The lower end of the first air duct 1 is equipped with a first air inlet 7, and the lower end of the second air duct 2 is equipped with a second air inlet 8.

[0023] The tubular heat exchanger includes an outer shell 9 and a V-shaped tube 10. The V-shaped tube 10 is disposed inside the outer shell 9, and its two ends are flush with the two ends of the outer shell 9. The upper end of the V-shaped tube 10 is connected to the wall of the outer shell 9. A cavity 11 is formed outside the V-shaped tube 10 inside the outer shell 9. An inlet 12 and an outlet 13 are respectively provided at the lower cavity 11 of the V-shaped tubes 10 at both ends of the outer shell 9. One end of the end tube 6 is connected to the inlet 12.

[0024] The air outlet pipe 3 is provided with an inner pipe 14 that is connected to the pipe wall of the lower end of the air outlet pipe 3. The lower end of the inner pipe 14 is connected to the end of the V-shaped pipe 10 that is adjacent to the inlet 12.

[0025] The upper end of the air outlet pipe 3 is provided with a rain cover 15.

[0026] In practical implementation, the device is first installed on the exterior wall. One end of the indoor air conditioner pipe is inserted into the outlet 13 of the cavity 11 on the outer casing 9. Outdoor air enters the first air inlet 7 at the lower end of the first air duct 1 and the second air inlet 8 at the lower end of the second air duct 2. Then, it enters the cavity 11 inside the outer casing 9 through the end pipe 6, and then enters the air conditioner through the air conditioner pipe, and finally enters the room. In this way, fresh outdoor air can be blown into the room through the "chimney effect". Utilizing this "effect", a "negative pressure" is formed at the outlet of the air outlet 3. Indoor air will then be discharged from the room through the V-shaped pipe 10, the inner pipe 14, and the air outlet 3 to expel indoor polluted gas. The honeycomb heat exchanger 5 structure is designed so that the heat exchange efficiency between the "cross-sectional area" of the honeycomb gaps and the "cross-sectional area" of the copper pipe can be greatly improved, making it direct, fast, and efficient. This greatly reduces the resistance and loss in the heat exchange process, and thus also reduces the power consumption of the air conditioner compressor to save energy.

[0027] A tubular heat exchanger works by balancing the temperature difference between incoming fresh air and outgoing polluted air through a heat exchange device. This minimizes energy loss and achieves energy savings.
