Description

Technical Field

[0001] This utility model relates to a passive house total heat exchange fresh air unit, belonging to the field of fresh air exchange equipment. Background Technology

[0002] Passive houses are energy-efficient buildings that achieve thermal insulation through their structural design. Therefore, the ventilation system needs to be optimized during the design phase to achieve this purpose. Currently, passive house ventilation systems are centrally controlled, using ducts to ventilate individual rooms. While this achieves ventilation, its effectiveness is limited; it only provides airflow and cannot replace indoor and outdoor air or regulate indoor temperature. To address these issues, the patent applicant has designed a total heat exchange fresh air unit suitable for passive houses. Summary of the Invention

[0003] The purpose of this invention is to provide a passive house heat exchange fresh air unit that uses the kinetic energy generated by the conversion of heat and cold to exchange fresh outdoor air into the room, while the original indoor air is discharged to the outside, thereby achieving indoor and outdoor air exchange and temperature regulation, and is low-carbon and energy-saving.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A passive house heat exchange fresh air unit includes a housing with a rhomboid heat exchange core in the center. A partition is arranged around the rhomboid edge of the heat exchange core, dividing the cavities on both sides of the housing into an upper and lower structure: an air inlet cavity, an air outlet cavity, a fresh air cavity, and a return air cavity. An air inlet hole is provided on the housing corresponding to the air inlet cavity, an air outlet hole is provided on the housing corresponding to the air outlet cavity, a fresh air hole is provided on the housing corresponding to the fresh air cavity, and a return air hole is provided on the housing corresponding to the return air cavity. The rhomboid heat exchange core is provided with an air inlet, an air outlet, a fresh air inlet, and a return air inlet. The air inlet hole, air inlet cavity, air inlet, fresh air inlet, fresh air cavity, and fresh air hole are interconnected. The return air hole, return air cavity, return air inlet, air outlet, air outlet, air outlet cavity, and air outlet are interconnected.

[0006] Furthermore, a side ventilation duct is provided on one side of the outer wall of the housing, and a side ventilation valve is provided in the side ventilation duct, which cooperates with the fresh air cavity.

[0007] Furthermore, an air intake fan is installed in the air intake cavity, and a primary filter screen is installed above the air intake fan.

[0008] Furthermore, a return air fan is installed in the return air cavity.

[0009] Furthermore, a fresh air high-efficiency filter and a return air high-efficiency filter are respectively installed on the fresh air inlet and the return air inlet.

[0010] This invention relates to a passive house total heat exchange fresh air system. During operation, fresh outdoor air enters the air inlet chamber through the air inlet, then flows through the air vent into the diamond-shaped total heat exchange core for total heat exchange. The fresh air then exits through the fresh air vent and is delivered into the room through the fresh air chamber and fresh air vent. Meanwhile, stale indoor air enters the return air chamber through the return air vent, then flows through the return air vent into the diamond-shaped total heat exchange core for total heat exchange, before exiting through the air outlet chamber and being delivered out through the air outlet. During the total heat exchange process, energy is fully recovered from both the fresh and stale air, reducing energy consumption while exchanging air, achieving energy conservation and environmental protection goals, making it ideal for passive houses.

[0014] The present invention will be described in detail below with reference to specific implementation examples. The following implementation examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way.

[0015] like Figure 1 — Figure 3 As shown, this utility model relates to a passive house total heat exchange fresh air unit, including a housing 1. A rhomboid total heat exchange core 2 is arranged in the center of the housing 1. A partition 3 is arranged with the rhomboid edge of the rhomboid total heat exchange core 2 as the center, dividing the cavities on both sides of the housing into an upper and lower structure: an air inlet cavity 4, an air outlet cavity 5, a fresh air cavity 6, and a return air cavity 7. An air inlet hole 8 is provided on the housing corresponding to the air inlet cavity 4, an air outlet hole 9 is provided on the housing corresponding to the air outlet cavity 5, a fresh air hole 10 is provided on the housing corresponding to the fresh air cavity 6, and a return air cavity 7 is provided on the housing corresponding to the return air cavity 7. The corresponding housing is provided with a return air hole 11. The rhomboid total heat exchange core 2 is composed of multiple heat exchange chips stacked together, which is existing technology. The figure shows a simplified schematic diagram. The rhomboid total heat exchange core 2 is provided with an air inlet 12, an air outlet 13, a fresh air inlet 14 and a return air inlet 15. The air inlet hole 8, air inlet cavity 4, air inlet 12, fresh air inlet 14, fresh air cavity 6 and fresh air hole 10 are interconnected. The return air hole 11, return air cavity 7, return air inlet 15, air outlet 13, air outlet cavity 5 and air outlet 9 are interconnected.

[0016] During operation, fresh outdoor air enters the air intake chamber 4 through the air inlet 8, then enters the diamond-shaped total heat exchange core 2 through the air inlet 12 for total heat exchange, resulting in fresh air. Fresh air then exits through the fresh air inlet 14, passes through the fresh air chamber 6 and the fresh air inlet 10, and is delivered into the room. Meanwhile, stale indoor air enters the return air chamber 7 through the return air inlet 11, then enters the diamond-shaped total heat exchange core 2 through the return air inlet 15 for total heat exchange, and exits through the air outlet 13, passes through the air outlet chamber 5, and is delivered out through the air outlet 9. During the total heat exchange process, energy is fully recovered from both the fresh and stale air, reducing energy consumption while replacing air, achieving energy conservation and environmental protection goals, making it highly suitable for passive house applications.

[0017] Furthermore, a bypass ventilation duct 16 is provided on one outer wall of the housing 1, and a bypass ventilation valve 17 is provided in the bypass ventilation duct 16. The bypass ventilation valve 17 cooperates with the fresh air chamber 6. With the bypass ventilation duct and bypass ventilation valve, when the machine is not started, outdoor air can enter the fresh air chamber 6 through the bypass ventilation duct and bypass ventilation valve, and then be sent into the room through the fresh air hole 10 to ventilate the room.

[0018] Furthermore, an air intake fan 20 is installed in the air intake cavity 4, and a primary filter 21 is installed above the air intake fan. With the air intake fan 20, it is easy for fresh outdoor air to enter the air intake hole 8, while the primary filter can filter out dust and particles and other larger substances, preventing such substances from entering the total heat exchange core and causing damage to the total heat exchange core.

[0019] Furthermore, a return air fan 22 is provided in the return air cavity 7 to facilitate the delivery of stale indoor air into the return air vent.

[0020] Furthermore, a fresh air high-efficiency filter 23 and a return air high-efficiency filter 24 are respectively installed on the fresh air inlet 14 and the return air inlet 15. The fresh air high-efficiency filter and the return air high-efficiency filter can filter substances such as pH value and PM2.5 in the air, purifying the air and the indoor and outdoor environment.

[0021] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
