Description

Technical Field

[0001] This invention belongs to the technical field of whole-house fresh air systems, and particularly relates to a whole-house fresh air system and a whole-house five-constant system that uses an active vertical duct to introduce fresh air. Background Technology

[0002] Among various whole-house fresh air system solutions (such as a room fresh air system that uses secondary negative pressure to supply fresh air and a whole-house fresh air system ZL202110746577.7), ductless air supply technology has a clear competitive advantage: it utilizes the air supply duct function of public spaces such as living rooms and corridors in residences to replace fresh air supply ducts, delivering centrally treated outdoor fresh air to the entrances of each room through the living room corridor, and then using the negative pressure of the air intake of the central air conditioning indoor unit at the room entrance to draw fresh air into each room for fresh air replacement, while a dedicated exhaust system extracts the stale air from each room and discharges it into the atmosphere; this "ductless air supply" whole-house bidirectional flow fresh air system with air supply through the living room corridor only requires one exhaust duct, which fundamentally solves the serious duct space interference problem caused by the need to install two sets of supply and return ducts in the ceiling of traditional bidirectional flow fresh air replacement schemes.

[0003] However, in practice, the biggest challenge in this type of "ductless air supply" whole-house bidirectional fresh air system that supplies air through the living room corridor and through the interior walls (doors) to enter the rooms is how to achieve this. If an opening is made in the door leaf, above the door frame, or in the inner wall to allow fresh air in, the opening will become a sound wave transmission channel between the room and the public space, undermining the room's enclosure and privacy. If an opening is made in the door leaf, above the door frame, or in the inner wall and an electric damper is installed to allow fresh air in, not only will the structure be complex, but it will also seriously affect the decorative aesthetics of the room's facade.

The cabinet is provided with a plurality of micro-perforated fresh air inlets or slotted fresh air inlets away from the waste air collection pipe.

[0022] Because the present invention adopts the above technical solution, it has the following advantages and positive effects compared with the prior art: ① Constructing a three-dimensional flow field in architectural space In one embodiment of the present invention, a passive vertical duct serves as an airflow channel connecting rooms and public spaces. Its staggered, oppositely positioned first and second air vents not only drive the two-dimensional movement of fresh air on the horizontal plane during the shaping of the airflow field in the rooms and public spaces, but also, through the low-intake, high-exhaust (or high-intake, low-exhaust) configuration of the first and second air vents, drive the vertical flow of fresh air in the public spaces and rooms. This constructs a three-dimensional flow field of fresh air within the suite, eliminating blind spots in fresh air replacement and improving fresh air replacement efficiency. Specifically, in the low-intake, high-exhaust scenario, fresh air enters the public space from a high position and is then drawn in from a low position by the active vertical duct, achieving three-dimensional flow of fresh air within the public space. Combined with the guide vane structure at the second air vent, this allows the fresh air to flow downwards and away from the return air from the room's stale air, achieving three-dimensional flow of fresh air within the room.

[0023] ② It effectively blocks the transmission of sound waves between the inside and outside of the room, providing good sound insulation. In one embodiment of the present invention, after fresh air is delivered into the public space from the single-pipe bidirectional flow whole-house fresh air system, it is propelled by the pressure difference formed by the positive pressure in the public space, the negative pressure in the room, and the exhaust at the relay power point. It then passes through the bend-shaped delivery channel formed by the first and second air inlets of the active vertical duct and the duct flow channel, ultimately delivering fresh air into the room, achieving fresh air replacement. Furthermore, the staggered and opposite arrangement of the first and second air inlets of the active vertical duct ensures that sound waves from the living room corridor and rooms must travel through the entire vertical duct and make two large-angle bends before entering and exiting the rooms. This effectively blocks sound wave transmission between the inside and outside of the rooms while simultaneously introducing fresh air from the public space into the rooms, resulting in excellent sound insulation.

[0024] ③ Slight positive pressure operation In one embodiment of the present invention, the power of the relay power point and the power of the negative pressure power point are adjusted to regulate the relationship between the air volume of the active vertical duct and the return air volume at the room's stale air return end, so as to maintain the air volume of the vertical duct being greater than the return air volume, thereby establishing a slightly positive pressure state between the room and the outside environment and preventing untreated ambient air from leaking into the room.

[0025] ④ Proactive operation One embodiment of the present invention achieves active operation by setting relay power points. It can also operate efficiently without relying on the slight pressure difference formed between the positive and negative pressure power points inside and outside the room, even when the door is open and there is no pressure difference between the inside and outside of the room. In this embodiment, the active vertical air duct spans the interior wall of the room, connecting the inside and outside of the room, linking the fresh air supplied by the positive pressure power point and the stale air extracted by the negative pressure power point, becoming the relay power in the whole-house bidirectional flow fresh air system link.

Detailed Implementation

[0028] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a comprehensive overview of the present invention, including an active vertical duct-based whole-house fresh air system and a whole-house five-constant system. The advantages and features of the invention will become clearer from the following description and claims.

[0029] Example 1 See Figures 1 to 3 In one embodiment, an active vertical duct 1 is used to introduce fresh air into a whole-house fresh air system for a group of rooms, the group of rooms including multiple rooms and a public space connected to each room, the whole-house fresh air system including a single-pass bidirectional flow whole-house fresh air system and at least one active vertical duct 1.

[0030] This single-pass bidirectional flow whole-house fresh air system is configured to directly or indirectly introduce fresh air into the public space through positive pressure power points, and is also configured to construct room stale air return ends 301 in one or more rooms through a single-pass duct system, in conjunction with negative pressure power points to extract stale air from the rooms. In other words, by introducing fresh air under positive pressure into the public space and extracting stale air from the rooms, a negative pressure state is created within the rooms, thereby establishing a pressure difference between the public space and the rooms.

[0031] The active vertical duct 1 corresponds one-to-one with the room's waste air return end 301 and is arranged in the corresponding room. The active vertical duct 1 is configured to have a first air outlet 101 facing the public space and a second air outlet 102 facing the room. The first air outlet 101 and the second air outlet 102 are arranged vertically away from each other (the first air outlet 101 is the air inlet and the second air outlet 102 is the air outlet; specifically, the first air outlet 101 can be arranged at the lower end and the second air outlet 102 at the upper end, or the first air outlet 101 can be arranged at the upper end and the second air outlet 102 can be arranged at the upper end) and are connected by the duct flow channel 103 formed by the inner wall of the active vertical duct 1. The duct flow channel 103 is used to dissipate the sound wave transmission between the public space and the room. The purpose of the far-away arrangement is to extend the distance that the sound waves travel in the active vertical duct as much as possible for dissipation.

[0032] The ventilation duct 103 is equipped with a relay power point, which is configured to draw fresh air from the public space through the first air outlet 101 and output it to the room with positive pressure through the second air outlet 102 (i.e., the relay power point further pulls fresh air from the public space into the room). The vertical distance between the first air outlet 101 and the second air outlet 102 is greater than 1 / 2 of the room height.

[0033] In this embodiment, fresh air is injected into public spaces such as the living room and corridor by the positive pressure power point of the single-pipe bidirectional flow whole-house fresh air system, while stale air is extracted from each room by the negative pressure power point. Driven by the relay power point in the active vertical air duct 1, the fresh air in the living room and corridor flows from bottom to top (or from top to bottom) through the active vertical air duct 1 and enters the room space at a certain speed and direction angle, driving the stale air in the room into the return air duct, thereby realizing the replacement of the room with fresh air.

[0034] The following is a further explanation of the specific structure of the whole-house fresh air system that introduces fresh air through the active vertical duct 1 in this embodiment: In this embodiment, the first air outlet 101 can be set at a low position, and the second air outlet 102 can be equipped with a guide vane structure for adjusting the air outlet direction, thereby realizing a low-intake and high-exhaust scenario. In the low-intake and high-exhaust scenario (since fresh air usually enters the public space at a high position, and the room's stale air return air outlet is usually also arranged at a high position), the fresh air enters the public space at a high position and is then drawn in at a low position by the active vertical air duct 1, realizing the three-dimensional flow of fresh air in the public space. With the help of the guide vane structure set at the second air outlet 102, the fresh air can flow downward and in a direction away from the room's stale air return air end 301, realizing the three-dimensional flow of fresh air in the room.

[0035] The second air vent 102 can be rectangular or frustum-shaped, and the guide vane structure can specifically be a guide vane group that can swing up and down and / or swing left and right, to control the speed and direction of the fresh air outlet. The first air vent 101 can be provided with a decorative structure including an air inlet channel, specifically a lattice window, a louver, or other openwork structure.

[0036] In this embodiment, the first air outlet 101 and the second air outlet 102 of the active vertical air duct 1 are set in opposite directions and at different heights. Sound waves from the living room corridor and the room need to go through the entire vertical air duct and make two large-angle turns before entering and leaving the room. While connecting the inside and outside of the room to bring fresh air into the public space, it also effectively blocks the transmission of sound waves between the inside and outside of the room, resulting in good sound insulation.

[0037] In this embodiment, the aforementioned active vertical duct 1 can be installed on the partition wall between the room and the public space, preferably installed or integrated into the door frame 2 of the room. Specifically, the active vertical duct 1 can be configured to match the height of the door frame 2 and can be located on the side of the door frame 2 away from the room's stale air return end 301 to optimize the fresh air replacement effect within the room. Furthermore, the active vertical duct 1 is matched to the side of the door frame 2 of the room door 6, and its actual height can be set to correspond to or exceed the height of the door frame 2. Specifically, the height difference between the first air outlet 101 and the second air outlet 102 can be greater than 2000mm to obtain the required length of the duct flow channel 103 for dissipating sound transmission between the inside and outside of the room.

[0038] Furthermore, the cross-sectional area of ​​the aforementioned air duct 103 can be specifically set to be greater than or equal to 0.014 m². 2 This allows for a fresh air volume of 150m³ / s in the room at a wind speed of 3m / s. 3 The air volume is above / h to meet the required fresh air replacement air volume. Specifically, the cross-section of the air duct 103 can be a 120mm×120mm square cross-section, a 100mm×144mm rectangular cross-section, or a similar cross-section.

[0039] In this embodiment, the single-pass bidirectional flow whole-house fresh air system may specifically include a single-pass duct system, a main fresh air module, and a main exhaust module. The single-pass duct system may include a main exhaust duct 5 and several room exhaust ducts 3.

[0040] The main fresh air module is located on the exterior wall of the public space and connects the public space to the environment, or it is located on the exterior wall of a room and connects the public space to the environment via a section of air supply duct 401. The main fresh air module is configured to introduce fresh air from the environment under positive pressure to establish a fresh air supply in the public space. The main exhaust module is connected to the exhaust ducts 3 of each room via the main exhaust duct 5. The main fresh air module is the positive pressure power point mentioned above, and the main exhaust module is the negative pressure power point mentioned above.

[0041] The main fresh air module is located on the exterior wall of the public space (either installed on the exterior wall of a room or on an equipment platform, extending into the public space through the main air supply duct 14) and is configured to introduce fresh air under positive pressure to establish a fresh air supply in the public space, thus utilizing the public space as an air supply channel. Specifically, the main fresh air module can be configured as a module with only fresh air filtration functions (air freshness and cleanliness), or it can be configured as a module with fresh air filtration, summer fresh air cooling and dehumidification, and winter fresh air heating and humidification units, undertaking the task of regulating the air freshness, cleanliness, and temperature and humidity within the building space.

[0042] The main exhaust module forms a room exhaust return air end 301 in the corresponding room through the main exhaust duct 5 and the room exhaust ducts 3. The room exhaust return air end 301 is configured to extract exhaust air to create a negative pressure extraction state in the room. Specifically, the negative pressure end of the main exhaust module can be connected to a main exhaust duct 5, and the room exhaust ducts 3 of each room can be connected to the main exhaust duct 5, thereby realizing negative pressure extraction of exhaust air from multiple rooms.

[0043] In this embodiment, the aforementioned relay power point is a centrifugal fan 106 installed in the air duct flow channel 103, specifically an external rotor centrifugal fan 106.

[0044] In this embodiment, the horizontal cross-section of the active vertical duct 11 can be set as a circular or rectangular structure, preferably a rectangular structure. The wall panels of the active vertical duct 11 can be made of metal, inorganic, organic or combined materials, preferably polymer synthetic materials. Furthermore, to improve the sound insulation effect, sound-absorbing material can also be attached to the inner wall of the active vertical duct 11.

[0045] In this embodiment, the active vertical air duct 1 is matched with the door frame 2 and has a slender structure. The inner surface is covered with sound-absorbing material. In particular, its first air outlet 101 and second air outlet 102 are set in opposite directions with staggered vertical positions. Sound waves from the living room corridor and the room need to pass through the entire vertical air duct and make two large-angle turns before entering and exiting the room. While connecting the inside and outside of the room to bring fresh air into the room from the public space, it also realizes the three-dimensional flow of fresh air in the interior space and effectively blocks the transmission of sound waves between the inside and outside of the room, resulting in good sound insulation.

[0046] Example 2 See Figure 4 and Figure 5 Based on the first embodiment described above, this embodiment further improves the interior of the air duct 103. Based on the centrifugal fan 106 in the first embodiment, at least one sound-absorbing layer 107 is provided in the air duct 103. The sound-absorbing layer 107 is configured to allow airflow to pass through, that is, the centrifugal fan 106 generates the required pressure difference to drive the airflow in the air duct 103 through the sound-absorbing layer 107. The setting of the sound-absorbing layer 107 can also make the sound absorption effect of the vertical air duct better (more fully degrade and absorb indoor and outdoor noise and fan operation noise propagating in the airflow).

[0047] Specifically, there may be two or more sound-absorbing layers 107, which are respectively arranged upstream and downstream of the airflow at the relay power point, that is, upstream and downstream of the fan. Specifically, they may be located between the fan and the first air outlet 101, and between the fan and the second air outlet 102.

[0048] Example 3 See Figures 6 to 8 This embodiment further provides a whole-house fresh air system that introduces fresh air through an active vertical duct 1, based on the above-described embodiments one and two. In this embodiment, a first sliding electric damper 105 is provided at the second air outlet 102 of the active vertical duct 1. The first sliding electric damper 105 is used to adjust the air outlet area to control the air outlet speed for scanning fresh air replacement in the room.

[0049] The first sliding electric damper 105 can be specifically set inside the second air outlet 102. By sliding the damper, the area of ​​the second air outlet 102 covered is controlled to change, thereby adjusting the remaining effective ventilation area and adjusting the air outlet speed and range of the second air outlet 102. It works in conjunction with the room's waste air return end 301 to perform zoned fresh air replacement in the indoor space. For example, as the electric damper slides from bottom to top, the area of ​​the second air outlet 102 covered by the damper gradually increases, the remaining effective ventilation area gradually decreases, the air outlet speed gradually increases, and the range gradually increases. It sequentially performs scanning fresh air replacement in the adjacent area (Zone C), the mid-distance area (Zone B), and the far-distance area (Zone A) of the vertical air duct in the room, resulting in higher fresh air replacement efficiency.

[0050] Example 4 See Figure 9 and Figure 10 This embodiment provides a whole-house fresh air system that introduces fresh air through an active vertical duct 1, based on the above embodiments one to three. In this embodiment, the active vertical air duct 1 is also provided with a low-position third air outlet 104 facing the room. The low-position third air outlet 104 and the second air outlet 102 are arranged vertically away from each other and connected by the air duct channel 103 (specifically, the first air outlet 101 and the third air outlet 104 are both set at low positions and away from each other, while the second air outlet 102 is set at a high position). The air duct channel 103 is provided with a finned tube heat exchanger 108 located between the second air outlet 102 and the third air outlet 104 (the finned tube heat exchanger 108 is connected to the refrigerant pipeline of the outdoor air conditioning unit, and a water tank 109 can be set below the finned tube heat exchanger 108 to receive condensate. The water tank 109 can be connected to the active vertical air duct 1 through a drain pipe 110). Thus, the air flowing through the air duct channel 103 can be cooled or heated through the finned tube heat exchanger 108, so that the active vertical air duct 1 can become the indoor unit of the air conditioner for the room.

[0051] Furthermore, a second sliding-plate electric damper and a third sliding-plate electric damper 111 can be respectively installed at the first air vent 101 and the third air vent 104. The second sliding-plate electric damper and the third sliding-plate electric damper 111 are used to open and close the first air vent 101 and the third air vent 104, respectively. By controlling the second sliding-plate electric damper and the third sliding-plate electric damper 111, the dual functions of indoor air circulation and indoor fresh air replacement can be realized.

[0052] In this embodiment, by adding a finned tube heat exchanger 108, three air outlets, a second sliding electric damper, and a third sliding electric damper 111 to the active vertical air duct 1, and linking them with the air conditioning unit, the main fresh air module, and the main exhaust air module, four room-based recirculating air conditioning and / or room fresh air replacement operation modes can be realized: ① Internal circulation air conditioning mode---the third sliding electric damper 111 opens, the second sliding electric damper closes, the air conditioning unit and the vertical air duct fan are started, and the room internal air circulation is regulated; ② Fresh air replacement mode---The second sliding electric damper opens and the third sliding electric damper 111 closes, starting the main fresh air module, the main exhaust module and the vertical air duct fan to perform fresh air replacement in the room; ③ Fresh air conditioning mode---The second sliding electric damper opens and the third sliding electric damper 111 closes, starting the air conditioning unit, main fresh air module, main exhaust air module and vertical air duct fan to perform fresh air conditioning in the room; ④ Room fresh air replacement + room internal air circulation mode---The second sliding electric damper and the third sliding electric damper 111 are both opened, the air conditioning unit, the main fresh air module, the main exhaust module and the vertical air duct fan are started, and the room fresh air replacement + room internal air circulation function is executed. In this embodiment, the finned tube heat exchanger 108 in the vertical air duct adopts a low-suction, high-exhaust airflow design in the room circulation air conditioning mode, which solves the problem of three-dimensional airflow in the room that companies in the household air conditioning industry have been striving for. In particular, it solves the problem that heat accumulates in the upper part of the room and is difficult to heat the area near the floor when the indoor unit of a traditional wall-mounted unit or traditional duct unit is heating in winter.

[0053] Example 5 See Figures 20 to 23 Based on embodiments one to four above, this embodiment provides a whole-house fresh air system with an active vertical duct 1 for introducing fresh air. The difference is that the single-pass bidirectional flow whole-house fresh air system has been adjusted. Specifically, the whole-house fresh air system is changed from a single-pass bidirectional flow whole-house fresh air system with ductless air supply to public spaces and return air to rooms to a single-pass bidirectional flow whole-house fresh air system with fresh air supply to rooms and ductless exhaust to public spaces, with supply as the main component.

[0054] The whole-house fresh air system is also used in a group of rooms, which includes multiple rooms and public spaces connected to each room. The whole-house fresh air system includes: a single-pass bidirectional flow whole-house fresh air system and at least one active vertical air duct 1.

[0055] The single-pass bidirectional flow whole-house fresh air system is configured to construct a fresh air supply terminal in one or more rooms through a single-pass duct system and introduce ambient fresh air in conjunction with positive pressure power points, and is configured to exhaust sludge directly or indirectly from outside the public space through negative pressure power points.

[0056] The active vertical air duct 1 corresponds one-to-one with the fresh air supply end of the room and is arranged in the corresponding room. The active vertical air duct 1 is configured to have a first air outlet 101 facing the public space and a second air outlet 102 facing the room. The first air outlet 101 and the second air outlet 102 are arranged vertically away from each other (the first air outlet 101 is the air outlet and the second air outlet 102 is the fresh air inlet. Specifically, the first air outlet 101 can be arranged at the lower end and the second air outlet 102 at the upper end, or the first air outlet 101 can be arranged at the upper end and the second air outlet 102 can be arranged at the upper end) and are connected by the air duct flow channel 103 formed by the inner wall of the active vertical air duct 1. The air duct flow channel 103 is used to dissipate the sound wave transmission between the public space and the room.

[0057] The ventilation duct 103 is equipped with a relay power point, which is configured to draw fresh air from the room through the second air outlet 102 and output it to the public space with positive pressure from the first air outlet 101. The vertical distance between the first air outlet 101 and the second air outlet 102 is greater than 1 / 2 of the room height.

[0058] Specifically, a single-pass bidirectional flow whole-house fresh air system may include a single-pass duct system, a main fresh air module, and a main exhaust air module. The single-pass duct system includes a main fresh air duct and several room fresh air ducts 15.

[0059] The main exhaust module is located on the exterior wall of the public space and connects the public space to the environment, or it is located on the exterior wall of a room and connects the public space to the environment via a section of supply air duct 401. The main exhaust module is configured to exhaust waste air to establish a negative pressure extraction state in the public space. The main fresh air module is connected to the fresh air ducts 15 of each room via a main fresh air duct. The main fresh air module is a positive pressure power point, and the main exhaust module is a negative pressure power point.

[0060] The main exhaust module can be installed on the exterior wall of a public space and connected to the public space and the environment, or installed on the exterior wall of a room and connected to the public space and the environment through a section of exhaust duct. The main exhaust module is configured to extract stale air through its public space return air inlet 16 located in the public space to establish a negative pressure extraction state in the public space.

[0061] In operation, the single-pass bidirectional flow fresh air system in this embodiment focuses on room ventilation, delivering fresh air to each room through the single-pass duct system (i.e., the main fresh air duct and the room fresh air duct 15) and collecting the stale air from each room into the living room corridor public space and finally exhausting it to the outdoor ambient air. This constructs a whole-house bidirectional flow fresh air link that starts from and ends in the outdoor environment: "Ambient fresh air → Main fresh air module → Main fresh air duct → Room fresh air duct 15 → Room air inlet damper → Room main space → Room air outlet damper (i.e., active vertical duct 1) → Living room corridor public space → Main exhaust module → Outdoor ambient air".

[0062] The whole-house fresh air system of this embodiment will be further described below: This embodiment adopts a single-pass fresh air supply duct whole-house bidirectional flow fresh air system, in which the main supply air duct and exhaust air duct do not intersect; the entire air path link is set with 3 power points; the main exhaust air module's air intake is directly connected to the public space or connected to the public space through a section of exhaust air duct, preferably connected to the top space of the public space that is close to the return air vents of each room through a section of exhaust air duct; this section of exhaust air duct is short in length, large in diameter, and does not interfere with the main supply air duct.

[0063] This embodiment describes a whole-house bidirectional fresh air system using a single-pass fresh air supply duct. The main components of the airflow path are an active vertical duct 1, a sleeve-type sliding damper 8, a main fresh air module, and a main exhaust air module or a main inlet / outlet air module 4. The airflow path has several important nodes: the main fresh air module, the room fresh air inlet, the active vertical duct 1 (room return air inlet), and the main exhaust air module. If the fresh air module and exhaust air module are combined into a main inlet / outlet air module 4, then it has three important nodes: the main inlet / outlet air module 4, the room fresh air inlet, and the active vertical duct 1 (room return air inlet).

[0064] The following is a detailed explanation of these important nodes: ① Main fresh air module In this embodiment, the main fresh air module is a central fresh air module that performs air conditioning treatment on the fresh air. It is the core component of a ductless exhaust and supply combined with a supply-oriented bidirectional flow fresh air system for the whole house. Specifically, it includes the structure and functions of fresh air filtration, fresh air dehumidification, and winter fresh air heating and humidification. It undertakes the task of regulating the freshness, cleanliness, and humidity of the air in the building space. The main fresh air module pressurizes the air-conditioned fresh air and pressurizes it into the main fresh air duct, which flows into the room fresh air ducts 15 that connect to the fresh air inlets of each room. The fresh air is then delivered to each room (including public spaces) under positive pressure through the fresh air inlets. In this embodiment, the main fresh air module is a main fresh air module that performs air conditioning treatment on the fresh air. It can be set up independently, for example, independently set up on the south balcony of the apartment structure, and set far away from the main exhaust air module on the north side of the apartment structure; or it can be set up in combination with the main exhaust air module, for example, the main exhaust air module can be combined to become the main air intake and exhaust module 4 set up on the north balcony. This embodiment uses a total heat exchanger fresh air module with a finned tube heat exchanger 108. The total heat exchanger exchanges sensible and latent heat between the fresh air and return air. The finned tube heat exchanger 108 is connected to the refrigerant circuit of the air conditioning unit to cool and dehumidify (heat up) the fresh air flow again. Although this fresh air module still has problems such as low heat exchange intensity, easy freezing of hot fluid channels in cold seasons, and difficulty in cleaning air duct contamination, its advantages are also very obvious, such as long time in the market, mature product design, manufacturing and installation technology, long-term large-scale sales leading to customer accumulation, and a mature and stable component supply chain.

[0065] ② Room fresh air inlet (i.e., the room fresh air supply end mentioned above) In this embodiment, the room fresh air inlet structure controls the flow and direction of fresh air in the room; the opening and closing of the fresh air inlet structure in each room (including public spaces) and the flow control are of great significance for realizing large-volume fresh air replacement in different areas within the suite, positive and negative pressure control in different areas, and small-volume, high-pressure-difference fresh air replacement in enclosed spaces such as wardrobes, cabinets, shoe cabinets, and bathroom cabinets. In this embodiment, the room's fresh air inlet adopts a sleeve-type sliding air valve 8 with a semi-cylindrical cross-section. The outer sleeve is fixed, and the inner sleeve slides. By changing the relative relationship between the inner and outer sleeves, the air inlet can be aligned (ventilated) or misaligned (closed).

[0066] This embodiment provides a sleeve-type sliding air valve 8, which includes an inner cylinder 801, an outer cylinder 802, and a drive system.

[0067] The outer cylinder 802 includes a first overlapping area, a ventilation hole area, a second overlapping area, and an inner cylinder 801 dwelling area; the inner cylinder 801 includes a third overlapping area, a covering area, and a fourth overlapping area. The cross-sectional structure of the inner cylinder 801 and the outer cylinder 802 is the same, and can be one of the following: triangular, rectangular, grooved rectangular, cylindrical, semi-cylindrical, or isosceles trapezoidal.

[0068] Both the inner cylinder 801 and the outer cylinder 802 are columnar thin-walled structures, with the inner dimension of the outer cylinder 802 cross-section being slightly larger than the outer dimension of the inner cylinder 801 cross-section.

[0069] The drive system includes a drive motor 804 and a push rod 803. The drive motor 804 and the push rod 803 are located inside the inner cylinder 801. A crossbeam is provided at the front end of the push rod 803, and the crossbeam is perpendicular to the push rod 803. The crossbeam is symmetrically arranged with axial straight gaps connecting to the inner cylinder 801 wall. The connection point between the push rod 803 and the crossbeam is located at or near the geometric center point of the inner cylinder 801 wall.

[0070] When the sleeve-type sliding air valve 8 is opened in this embodiment, the drive motor 804 and the push rod 803 push the inner cylinder 801 to slide on the inner surface of the outer cylinder 802. The inner cylinder 801 partially or entirely slides to the dwell area. The ventilation hole area on the wall of the inner cylinder 801 partially or entirely overlaps with the ventilation opening of the outer cylinder 802. Under the positive pressure of the air supply module and the air supply pipeline, fresh air flows into the room through the ventilation hole area of ​​the inner cylinder 801 and the outer cylinder 802. The stale air in the room then passes through the vertical air duct and is discharged into the public space, thus implementing fresh air replacement in the room.

[0071] When the sleeve-type sliding air valve 8 is closed in this embodiment, the drive motor 804 pushes the push rod 803 to push the inner cylinder 801 to slide on the inner surface of the outer cylinder 802. The inner cylinder 801 is completely separated from the residence area. The ventilation hole area on the wall of the inner cylinder 801 does not overlap with the ventilation opening of the outer cylinder 802. Under the positive pressure of the air supply module and the air supply pipeline, the cylinder wall of the inner cylinder 801 is pressed against the inner wall of the outer cylinder 802, the fresh air supply outlet of the room is closed, and the fresh air replacement of the room is terminated.

[0072] ③ Room return air vent In this embodiment, the room return air vent is the outlet for stale air from the room to enter the living room corridor public space, connecting the main room space with the public space outside the room. The structure of the room return air vent must meet the requirements of isolating the transmission of sound between the inside and outside of the room, minimizing airflow resistance, and coordinating the three-dimensional flow of fresh air in the public space and the room.

[0073] In this embodiment, the room return air vent can be an active vertical air duct 1 set on the side of the room door 6. For the specific structure, please refer to the above embodiments.

[0074] When the vertical duct is running in this embodiment, under the combined drive of the positive pressure of the main fresh air module and the negative pressure of the main exhaust air module, the second air outlet 102 directs the polluted airflow from the room to the public space. The polluted airflow avoids the main space in the lower middle part of the living room corridor and flows in a short-circuit manner close to the ceiling of the living room corridor towards the main return air outlet of the public space.

[0075] ④ Main exhaust module In this embodiment, the main exhaust module for external waste air can be set up independently or combined with the main fresh air module. The air intake of the main exhaust module is directly connected to the public space or connected to the public space through a section of exhaust duct. Preferably, it is connected to the ceiling space of the restaurant that is close to the return air vents of each room through a section of exhaust duct. This section of exhaust duct is relatively short and has a large diameter, and does not interfere with the air supply duct. The main exhaust module is responsible for collecting, pressurizing, and high-speed, long-range exhausting of the waste air from the return air vents 1616 of each room and public space into the atmosphere. This embodiment uses a rearward centrifugal fan 106 to drive the main exhaust module. This main exhaust module is combined with the main fresh air module to form an integrated main air inlet and outlet module 44 with a total heat exchanger as the core.

[0076] In this embodiment, a whole-house bidirectional fresh air system using a single-pass fresh air supply duct is operated as follows: The main fresh air module of the main air inlet and outlet module 4 injects positive pressure fresh air after air conditioning treatment (cooling and dehumidifying in summer and heating and humidifying in winter) into the main fresh air duct, and then delivers it to the fresh air inlets of each room through several room fresh air ducts 15. After the air volume and speed are adjusted by the sleeve-type sliding air valve 8 of the room fresh air inlet, it is injected into the main space of the room, driving the stale air in the room through the low-position return air inlet of the active vertical air duct 11 from bottom to top and into the top space of the living room corridor; The main exhaust module of the main air inlet and outlet module 4 is connected to the main return air inlet through a section of exhaust duct, generating negative pressure in the top space of the dining room that is close to the return air inlets of each room. The negative pressure guides the stale air delivered from the return air inlets 16 of each room and public space to converge close to the ceiling and face the main return air inlet, flow into the exhaust duct, and finally enter the exhaust module for pressurization, high-speed and long-range discharge into the atmosphere for diffusion and dilution. In this embodiment, the main fresh air module and the main exhaust air module in the main air intake and exhaust module 4 are combined by push and pull, constructing a whole-house bidirectional flow fresh air open-loop link that starts from the outdoor environment and ends at the outdoor environment: "Ambient fresh air → Main fresh air module of main air intake and exhaust module 4 → Main fresh air duct → Fresh air duct 15 of fresh air room → Room air inlet sleeve-type sliding air valve 8 → Main room space → Room air outlet (active vertical air duct 1) → Living room corridor public space → Main exhaust air module of main air intake and exhaust module 4 → Outdoor ambient atmosphere".

[0077] The advantages of this embodiment of a whole-house bidirectional fresh air system using a single-pass fresh air supply duct are: ① Provide efficient, economical, and clean fresh air systems for building spaces This embodiment describes a whole-house bidirectional fresh air system using a single-pass fresh air supply duct to serve a group of rooms. It explores the potential of the "exhaust duct" in the living room and corridor public space, focusing on room ventilation. Fresh air is delivered to each room through the supply duct, and exhaust air from each room is collected in the living room and corridor public space and finally extracted by the exhaust module and discharged to the outdoor environment. This constructs a whole-house bidirectional fresh air open-loop link that starts from and ends in the outdoor environment: "Ambient fresh air → Main fresh air module 4 of main inlet and outlet air module → Main fresh air duct → Room fresh air duct 15 → Room air inlet damper → Room main space → Room air outlet damper → Living room and corridor public space → Main exhaust module 4 of main inlet and outlet air module → Outdoor environment atmosphere".

[0078] This embodiment solves the problems of ductless air supply and exhaust combined with exhaust-oriented bidirectional airflow fresh air system that delivers polluted air from noisy public spaces into rooms, and the potential for smoke and alcohol fumes from smoking, drinking, or eating hot pot in the living room and dining room of a residential unit to spread pollution to other rooms.

[0079] In this embodiment, the vertical air duct in the room fresh air system serves as an airflow channel connecting the room and the public space. Its structural features, with the air inlet and outlet staggered and arranged in opposite directions, not only provide good sound insulation and promote the two-dimensional movement of fresh airflow on the horizontal plane, but also drive the vertical flow of fresh airflow through the low-intake and high-exhaust (or high-intake and low-exhaust) of its air inlet and outlet. This creates a three-dimensional flow field of fresh airflow in the room, eliminates blind spots in fresh air replacement, and improves fresh air replacement efficiency.

[0080] This embodiment only requires one set of fresh air supply ducts, which solves the problems of severe spatial interference between the two sets of fresh air supply and waste air exhaust ducts, as well as severe spatial interference between the two sets of supply and return air ducts and the building beams in the suspended ceiling. It reduces the construction difficulty and cost of the fresh air supply duct, increases the net height of the indoor space, and provides the most efficient, economical, clean and reliable fresh air replacement system for residential spaces.

[0081] ② Implement high-flow fresh air replacement The actual air volume of existing residential fresh air systems is mostly around 300m³. 3 With a capacity of less than 1 / h, replacing the air in a 200㎡ residential space once still requires 2 hours, even with a 100% fresh air and stale air replacement efficiency where there is no mixing of fresh and stale air. Furthermore, the airflow velocity in the existing φ110 main fresh air duct and main exhaust duct 5 is close to 10m / s, making the airflow resistance and noise unbearable. In March 2025, the Ministry of Housing and Urban-Rural Development issued the national standard "Residential Project Specification", which raised the residential floor height to "not less than 3m". This was to address the feeling of spatial oppression after the expansion of residential area and room width, not to expand the vertical space of the ceiling where supply and exhaust ducts are installed. This embodiment utilizes the potential of the living room hallway exhaust duct to implement "ductless exhaust," constructing a whole-house bidirectional fresh air conditioning system with only one single-pass supply duct. The diameter (or rectangular duct cross-sectional area) of this single supply duct can be increased to approximately φ220, increasing the fresh air volume to 600m³. 3 When the airflow rate is above 100 m / h, the airflow velocity in the φ220 main fresh air duct is only 4.4 m / s. Compared with the existing fresh air system, this embodiment shows a significant reduction in airflow resistance and airflow noise under the condition of doubling the airflow. This is the first time that a large-diameter, high-flow-rate fresh air replacement system has been successfully implemented in the residential field. In this embodiment, it is sometimes necessary to add a section of exhaust duct before the air intake of the exhaust module, such as an exhaust duct that crosses the bathroom, but this section of exhaust duct does not interfere with the main air supply duct.

[0082] Example 6 See Figures 11 to 13This embodiment provides a whole-house five-constant system for a group of rooms, which includes multiple rooms and a public space connected to each room, including the whole-house fresh air system with active vertical duct 1 for introducing fresh air as described in embodiments one to five above.

[0083] This embodiment employs a whole-house five-constant system that introduces fresh air into the room via a vertical duct, based on the following analysis and judgment regarding the indoor air quality indicators, their status, and significance: ① Humans live in the air enclosed by reinforced concrete structures, not in reinforced concrete itself; therefore, reinforced concrete technology is the foundation, platform, and prerequisite technology of construction, while only air quality technology is the soul of construction technology; as the speed-driven real estate development represented by third-generation housing comes to an end, a new era of defining architecture by air quality is about to arrive! ② In an era where air quality defines architecture, building technologies, including HVAC technology, will revolve around the five dimensions of air quality in building spaces: freshness, cleanliness, quietness, temperature, and humidity. Through mechanical ventilation, filtration, sound insulation, cooling, dehumidification, heating, and humidification, these five dimensions are improved to achieve "five constants" and become "five constant systems." In an era where air quality defines architecture, fresh air conditioning technology is no longer a supporting role or gimmick after building structural technology, building material technology, and building process technology, but rather the protagonist and leader of building technology.

[0084] The whole-house five constant system in this embodiment serves a group of rooms. Taking the single-pass bidirectional flow whole-house fresh air system with a single exhaust pipe as an example, the living room and corridor public space replaces the supply air duct. Only one set of exhaust duct (main exhaust module, main exhaust pipe 5, room exhaust pipe 3) is set up to replace the traditional two sets of pipes, implementing a "pipeless supply and exhaust combined with exhaust as the main whole-house bidirectional flow fresh air system". In this embodiment, the main air supply duct and exhaust duct of the whole-house five constant system do not intersect; the entire air path link is set with only 2 power points; the air supply outlet of the main fresh air module is directly connected to the public space or connected to the public space through a section of air supply duct 401, preferably connected to the top space of the public space that is close to the fresh air outlet of each room through a section of air supply duct 401; this section of air supply duct 401 is short in length and large in diameter, and does not interfere with the main exhaust duct.

[0085] In this embodiment of the whole-house five-constant system, the main fresh air module of the whole-house fresh air system is configured to regulate the freshness, cleanliness, and humidity of the fresh air supplied to the public space. The whole-house five-constant system also includes a temperature control system, which is mainly responsible for controlling "quietness and temperature". The temperature control system can specifically be a radiant temperature control system.

[0086] The whole-house fresh air system of this embodiment will be described in detail below: The whole-house five-constant system fresh air system in this embodiment takes the active vertical air duct 1 as the core node and constructs a whole-house bidirectional flow fresh air link with two air path power points, starting from the outdoor environment and ending at the outdoor environment: "Ambient fresh air → main fresh air module → living room corridor public space → room vertical air duct → main room space → room exhaust duct 3 → residential unit exhaust duct (main exhaust duct 5) → main exhaust duct module → outdoor atmosphere".

[0087] The main fresh air module of the whole-house five constant system fresh air system in this embodiment includes fresh air filtration, summer fresh air cooling and dehumidification, and winter fresh air heating and humidification units, which are responsible for regulating the freshness, cleanliness, temperature and humidity of the air in the building space. The main exhaust module of the whole-house five constant system fresh air system in this embodiment includes a centrifugal fan 106, an inlet and outlet air chamber and an exhaust pipe, which is responsible for pressurizing and accelerating the exhaust of the stale air sent from the return air vents and exhaust pipes (main exhaust pipe 5, room exhaust pipe 3) of each room into the atmosphere. In this embodiment, the main fresh air module and the main exhaust air module can be set relatively far apart, with one set on the south side, such as the south balcony, and the other set on the north side, such as the north balcony; or they can be set adjacent to each other, such as both set on the north balcony. Furthermore, in this embodiment, the main fresh air module and the main exhaust air module can be designed to complement each other to form the main air intake and exhaust module 4, that is, to integrate the two into a single module.

[0088] The main air inlet and outlet module 4 uses a dual-fan unit for fresh air intake and stale air exhaust, a dual-channel total heat exchanger core, and a finned tube heat exchanger 108 connected to the refrigerant circuit of the air conditioning unit, located at the outlet of the fresh air channel. In summer, the fresh air flow passes through the total heat exchanger core and is cooled and dehumidified by the stale air flow before entering the finned tube evaporator for further cooling and dehumidification. In winter, the fresh air flow passes through the total heat exchanger core to recover heat and moisture from the stale air flow before entering the finned tube condenser for reheating, and finally is pressurized by the fresh air fan and sent into the interior space.

[0089] In this embodiment, the operation of the whole-house five-constant system fresh air system is divided into two stages: The first stage involves cleaning the living room corridor, which serves as the air supply channel. The main fresh air module injects filtered and dehumidified fresh air into the living room corridor, while the main exhaust air module extracts stale air from the living room corridor through the living room return air vent (which can be connected to the main exhaust duct 5 via the living room exhaust duct) located far from the main fresh air module's air supply vent. This stage first completes the fresh air replacement in the living room corridor.

[0090] In the second stage, fresh air replacement in each room occurs. The main fresh air module continuously injects filtered and dehumidified fresh air into the living room corridor, establishing a slight positive pressure in the corridor. Simultaneously (or at staggered times), the main exhaust module extracts stale air from each room, establishing a negative pressure state in each room. In this stage, the main fresh air module and the main exhaust module work together to establish a pressure difference between the first air outlet 101 and the second air outlet 102 of the vertical air duct in each room. Driven by this pressure difference, the fresh air in the living room corridor flows from bottom to top through the vertical air ducts of each room, surging into the room space at a certain speed and direction angle, driving the stale air in the room into the return air duct and then into the atmosphere through the main exhaust module, thus achieving fresh air replacement in all spaces within the apartment.

[0091] The control targets and responsibilities of the whole-house five-constant system fresh air system in this embodiment are mainly to stabilize the "freshness, cleanliness, and temperature and humidity" of the building space air. In particular, by precisely controlling the humidity of the building space, it ensures that the dew point temperature of the indoor air is significantly lower than the surface temperature of the radiant cooling surface (mainly the surface of the capillary plaster under the ceiling) to prevent condensation from occurring on the radiant cooling surface (when the temperature of the radiant surface is lower than the "dew point temperature" of the surrounding air, water vapor in the air will condense into water on the radiant surface. The dew point temperature depends on the air temperature and relative humidity. The higher the humidity, the closer the dew point temperature is to the dry bulb temperature of the air, and the easier it is for condensation to occur).

[0092] Condensation is a critical and common problem for radiant temperature control systems in cooling mode. The most direct and serious impact is damage to the building structure and finishes. Since radiant temperature control units 7 are typically located under the ceiling, condensation can cause water stains, discoloration, and yellowing on walls and ceilings, affecting aesthetics. Furthermore, long-term or repeated condensation can cause blistering, powdering, and peeling of putty, latex paint, and other coatings. For radiant temperature control units 7 located under the floor, condensation can damage the insulation layer beneath the floor, rendering it ineffective. It can also cause wooden floors to swell, warp, and mold.

[0093] The radiative temperature control system of this embodiment will be described in detail below: The radiant temperature control system may specifically include an air conditioning water chiller (installed on an equipment platform) and several radiant temperature control units 7 connected to the air conditioning water chiller. The radiant temperature control units 7 may be installed under the ceiling and / or floor and / or side walls of public spaces and at least one room. The surface of the radiant temperature control unit 7 facing the room or living room is the aforementioned radiant cooling surface. The air conditioning water chiller supplies air conditioning water to the radiant temperature control units 7, supplying low-temperature water in summer and warm water in winter. Radiant cooling and heating of indoor air is achieved through the large-area surface of the radiant temperature control units 7. The radiant temperature control unit 7 may be a radiant panel or a capillary water circuit.

[0094] The air conditioning water chiller may specifically include a refrigerant circuit consisting of a compressor, condenser, expansion valve, and evaporator, a control system, and a hydraulic module. The hydraulic module provides the power for the circulation of chilled water between the air conditioning water chiller and the indoor fan coil unit, and controls the pressure, flow rate, and heat distribution of the chilled water circuit. In this embodiment, the capillary radiant cooling and heating system has a water supply temperature of 18-21℃ in summer, a higher evaporation pressure, a lower compression ratio, and a higher system energy efficiency. In winter, the water supply temperature is 30-35℃, the condensation pressure is lower, the compression ratio is lower, and the system energy efficiency is higher.

[0095] The advantages of this embodiment are: ① Provide efficient, economical, clean and reliable fresh air systems for building spaces The radiant cooling surface of the current five constant systems is usually set under the ceiling, which occupies the top space; the fresh air system is to deliver fresh air to each room by laying air supply ducts under the floor and setting fresh air inlets on the floor of each room; such a five constant system fresh air solution not only increases the construction difficulty and cost of fresh air supply ducts, but also makes it easy for pollutants to fall into the second air inlet 102 and to blow up dust on the floor. It also reduces the net height of the space and makes it difficult to find the location of the room's stale air return air inlet and exhaust duct. In this embodiment, the active vertical air duct 1 in the fresh air system serves as an airflow channel connecting the room and the public space. Its first air outlet 101 and second air outlet 102 are staggered and set far apart and in opposite directions. In shaping the airflow field of the room and the public space, it not only promotes the two-dimensional movement of the fresh airflow on the horizontal plane, but also drives the vertical flow of the fresh airflow through the low intake and high exhaust (or high intake and low exhaust) of the first air outlet 101 and the second air outlet 102. This constructs a three-dimensional flow field of fresh airflow in the interior space, eliminates the blind spot of fresh air replacement, and improves the fresh air replacement efficiency.

[0096] The fresh air system in this embodiment uses the active vertical duct 1 as the core node, constructing a whole-house fresh air link that starts from and ends in the outdoor environment: "Ambient fresh air → main air intake and exhaust module 4 → living room corridor public space → active vertical duct 11 → main room space → room exhaust duct 3 → residential unit exhaust duct (main exhaust duct 5) → main air intake and exhaust module 4 → outdoor atmosphere". It develops the potential of the air supply duct in the living room corridor to implement "ductless air supply", setting only one exhaust duct. This solves the serious spatial interference problem between the two sets of air supply and return ducts and the structural beams in the suspended ceiling, the competition with the radiant temperature control unit 7 for ceiling and floor panel resources, and the problem of pollutants falling into the second air outlet 102 and blowing up the floating dust on the ground. It reduces the construction difficulty and cost of the exhaust duct, increases the net height of the space, and provides the most efficient, economical, clean and reliable fresh air link system for the whole-house five constant system.

[0097] ② Implement high-flow fresh air replacement The actual air volume of existing residential fresh air systems is mostly around 300m³. 3 For air exchange and replacement of the interior space of a 200㎡ residential building, even with a 100% fresh air and stale air exchange efficiency where fresh and stale air are completely unmixed, it still takes 2 hours. Furthermore, at this time, the airflow velocity in the φ110 main exhaust duct 5 is close to 10m / s, and the airflow resistance and noise are unbearable. This embodiment utilizes the potential of the fresh air supply duct in the living room corridor to implement "ductless air supply," constructing a whole-house bidirectional fresh air system with only one exhaust duct. The exhaust duct diameter in this embodiment can be increased to over φ220; the fresh air volume in this embodiment is 600m³. 3 Even with an airflow rate of over 1 h, the airflow velocity in the φ220 main exhaust duct 5 is only 4.4 m / s. Compared to the existing fresh air system, this embodiment reduces airflow resistance and noise by more than 50% under the condition of doubling the airflow, enabling the large-flow fresh air replacement of the five constant systems to be implemented. This embodiment may sometimes require the addition of a section of supply air duct 401, such as the supply air duct that crosses the bathroom, but this section of the main fresh air duct does not cause spatial interference with the main exhaust duct.

[0098] ③ Provides a wider range of surface source options for radiative cooling. This embodiment only requires one exhaust duct to solve the problem of bidirectional fresh air replacement throughout the house, eliminates the construction difficulty and cost of fresh air supply ducts in traditional five constant systems, increases the net height of the space, provides the most efficient, economical, clean and reliable fresh air link system for the whole house five constant systems, and frees up floor space. In this embodiment, radiant capillary tubes can be laid under the floor for winter heating, providing a wider range of surface source options for radiant cooling and heating. The floor radiant capillary tubes and the ceiling radiant capillary tubes can be used together and complement each other: in summer, ceiling radiant cooling is the main method, and in winter, floor radiant heating is the main method. This combination can bring out the greatest advantages and effects of combining radiant cooling technology with the natural convection of the building space.

[0099] ④ Complementary capabilities to radiant refrigeration systems While capillary radiant cooling (heating) systems have the advantages of being noiseless, highly energy-efficient, and having high spatial uniformity, they also have serious problems such as high thermal inertia and long start-up time. In this embodiment, the high-efficiency, high-volume fresh air system complements the capillary radiant cooling (heating) system. Users can use the fresh air system in this embodiment to quickly reach the target values ​​for indoor space temperature, humidity, cleanliness, and freshness to achieve comfort, while using the capillary radiant cooling (heating) system to adjust the temperature of the building envelope, such as walls, floors, and ceilings. After the building envelope temperature is adjusted to the desired level, the fresh air system stops operating or operates intermittently.

[0100] ⑤ The technological ideal of "defining architecture based on air quality" has been realized. Reinforced concrete technology is the foundational, platform, and prerequisite technology for construction. However, humans work and live in the air enclosed by reinforced concrete, not on reinforced concrete itself. Therefore, only air quality technology is the soul of building technology. This embodiment significantly improves the five-dimensional (five constants) quality of air freshness, cleanliness, quietness, temperature, and humidity in building spaces, transforming building fresh air technology from a supporting role in building structure technology, building material technology, and building process technology into the protagonist and leader of building technology, realizing the technological ideal of "defining buildings with air quality".

[0101] Example 7 See Figure 14 Based on the above embodiment five, this embodiment adjusts the temperature control system to a residential central air conditioning unit. The residential central air conditioning unit includes several room fan coil units. At least one room with an active vertical air duct 1 is equipped with a room fan coil unit, and the distance between the return air inlet of the room fan coil unit and the second air outlet 102 of the active vertical air duct 1 is less than the distance between the second air outlet 102 of the active vertical air duct 1 and the power point for exhausting the waste air.

[0102] This means that by using room fan coil units to create a secondary negative pressure (the lowest pressure zone in the room), a greater pressure difference is created between the public space and the room, so that fresh air can be more smoothly introduced into the room for fresh air replacement.

[0103] In this embodiment, the main fresh air module continuously injects filtered and dehumidified fresh air into the living room corridor, establishing a slight positive pressure in the corridor. Simultaneously (or at staggered times), the main exhaust module extracts stale air from each room, establishing a negative pressure state (primary negative pressure) in the room. The fans of the room fan coil units (indoor units of the residential central air conditioning system) operate in conjunction with the fans of the main exhaust module, generating an even lower negative pressure at the fresh air inlet of the room fan coil unit (secondary negative pressure, the lowest pressure zone in the room). The main fresh air module, the main exhaust module, and the room fan coil units work together to establish a pressure difference between the first air outlet 101 and the second air outlet 102 of the room's vertical air duct. Driven by this pressure difference, the fresh air in the living room corridor flows from bottom to top through the room's vertical air duct, rushing into the room space at a defined speed and direction angle, pointing towards the air inlet of the room fan coil unit, being sucked in by the fan coil unit, pressurized, and blown towards the exterior wall and windows. It is then reflected by the exterior wall and windows into the main space of the room, driving the stale air in the room into the return air duct and then into the atmosphere by the main exhaust module, thus achieving fresh air replacement in the room.

[0104] In this embodiment, when implementing fresh air replacement, the secondary negative pressure of the air intake of the room fan coil unit of the residential central air conditioning system is utilized to construct a whole-house bidirectional flow fresh air system with three power points. This forms a whole-house fresh air link that starts from and ends in the outdoor environment, namely, "environmental fresh air → main fresh air module → living room corridor public space → active vertical air duct 1 → room fan coil secondary negative pressure deep suction and high exhaust → main room space → room exhaust duct 3 → indoor exhaust duct (main exhaust duct 5) → main exhaust module → outdoor atmosphere". This whole-house bidirectional flow fresh air link develops the potential of the existing central air conditioning fan coil unit in the room to guide fresh air and further improves the fresh air replacement efficiency of the room.

[0105] Example 8 See Figure 15 This embodiment provides a whole-house five-constant system based on the above embodiment five. The active vertical duct 1 of this system is equipped with two speaker units 13 arranged vertically at intervals (specifically, on the side of the active vertical duct 1 facing the room). Additionally, a speaker unit 13 is provided at the room exhaust duct 3's room waste air return end 301 or the room fresh air supply end of the room fresh air duct 15 corresponding to the room. The three speaker units 13 work together to form a stereo sound system.

[0106] This embodiment adopts radiant cooling with radiant temperature control unit 7, eliminating the room fan coil unit and the ceiling that conceals the fan coil unit. The structure of the room's second air outlet 102 is exposed on the top of the room's interior wall.

[0107] In this embodiment, the structure of the second air vent 102 in the room can be designed and manufactured as an integral part of the speaker structure, thus providing concealment and decoration for the second air vent 102. The first air vent 101 in the room (the active vertical air duct second air vent 102) and the corresponding attached speaker can be in an upper-lower structural relationship. The room exhaust vent / room fresh air vent (room waste air return end 301 / room fresh air supply end) and the corresponding attached speaker can be a columnar speaker embedded in the exhaust vent, with the actual return air area of ​​the exhaust vent located on both sides of the columnar speaker. The appearance of the speaker on the lower indoor side of the vertical air duct can be the same as the speaker structure of the first air vent 101, or it can be similar in color to the doorpost.

[0108] By placing decorative speakers at three points—the first air inlet 101 of the whole-house fresh air system (the second air inlet 102 of the active vertical air duct 1), the return air inlet / fresh air inlet (the room exhaust duct 3 / room fresh air duct 15 located at one end in the room), and the bottom of the active vertical air duct 1 on the indoor side—they not only serve a decorative purpose on the structure of the second air inlet 102 in the room, but also create a dynamic three-dimensional spatial relationship and sound wave phase relationship with the cochlea of ​​the people staying in the room, producing a wonderful room stereo sound effect.

[0109] Example 9 The current status of existing residential cabinets is analyzed and assessed as follows: ① Enclosed storage systems such as wardrobes, cabinets, shoe cabinets, and bathroom cabinets in residential spaces are havens for dust, mold, and microorganisms, and are also accumulation sites for formaldehyde and benzene compounds. Only by solving the problems of ventilation, dehumidification, mold prevention, and formaldehyde and benzene compound discharge in these enclosed storage systems can the main sources of pollution in the main space of the residence be eradicated. ②Because enclosed storage spaces such as wardrobes, cabinets, shoe cabinets, and bathroom cabinets are distributed in a dispersed manner within a residence, it is impossible to construct an external ventilation system for each one independently. Instead, it is necessary to rely on a two-way fresh air replacement system throughout the entire residence. ③ Enclosed storage spaces such as wardrobes, cabinets, shoe cabinets, and bathroom cabinets have small volumes and are often filled with multiple layers of items. They are not suitable for large-volume fresh air replacement, but are suitable for micro-circulation ventilation with multiple micro-holes for fresh air intake and multiple micro-holes for stale air exhaust.

[0110] Based on the above analysis, it can be seen that the whole-house five-constant system needs to focus on ventilation, dehumidification, mold prevention, and the removal of formaldehyde and benzene compounds within the residential storage system. However, it is necessary to meet the requirements of micro-ventilation with a large pressure difference and small air volume in indoor closed storage systems such as wardrobes, cabinets, shoe cabinets, and bathroom cabinets to achieve dehumidification, mold prevention, and removal of formaldehyde and benzene compounds in the storage space, and at the same time, to meet the requirements of large air volume fresh air replacement in the interior space to achieve the five constant requirements of constant temperature, constant humidity, constant oxygen, constant cleanliness, and constant quietness. The current residential ventilation system is difficult to match such "both" requirements. This embodiment requires a large-scale innovation and creation in the main components and system integration of the ventilation system.

[0111] See Figures 16 to 19 Therefore, this embodiment provides a whole-house five-constant system based on the above embodiments four to six. The whole-house five-constant system also includes a storage subsystem micro-ventilation structure, which includes at least one cabinet exhaust pipe 10 connected to the main exhaust module and a waste air collection pipe 9 arranged in the corresponding cabinet. The return air end of the cabinet exhaust pipe 10 is connected to the waste air collection pipe 9. A plurality of cabinet return air inlets 901 are arranged at intervals on the waste air collection pipe 9. The cabinet is provided with a plurality of micro-perforated fresh air inlets 11 or slotted fresh air inlets away from the waste air collection pipe 9.

[0112] The micro-ventilation structure of the storage subsystem in this embodiment is a parallel bypass of the room's fresh air system. It is linked with the whole-house exhaust system to drive the discharge of formaldehyde and benzene pollutants accumulated in enclosed spaces such as wardrobes, cabinets, shoe cabinets, and bathroom cabinets. It also effectively reduces and controls the humidity in these enclosed spaces, prevents the proliferation of mold, bacteria, microorganisms, and bedbugs, and eliminates blind spots in the "freshness" and "cleanliness" of the room.

[0113] This embodiment adopts a micro-ventilation structure for residential storage systems such as wardrobes, cabinets, shoe cabinets, and bathroom cabinets. This includes a partition 1212 with through holes and / or slits inside the cabinet, and vertically arranged slits or multiple micro-holes for supplying fresh air and exhausting stale air.

[0114] More specifically, in this embodiment, for a wall-mounted wardrobe made of isotropic plywood particleboard, the bottom of the wardrobe (lower edge of the cabinet door or bottom panel) has several micro-holes of about φ3 (i.e., micro-hole fresh air inlets 11, specifically φ2-φ4) to connect the wardrobe interior with the indoor space. A φ30 internal waste air collection pipe 9 is horizontally installed at the top of the wardrobe interior, or a wind valve may also be provided; the waste air collection pipe 99 also has several micro-holes of about φ3 (i.e., cabinet return air inlets 901, specifically φ2-φ4) on its wall. When the waste air collection pipe 99... The system connects to the exhaust duct of the residential unit (i.e., the main exhaust duct 5, which opens synchronously if a duct valve is installed). Under the negative pressure generated by the return air vent 901 of the cabinet in the dirty air collection pipe 9, the system drives the dry airflow in the indoor space to pass through the multiple layers of perforated and / or slit partitions 12 inside the cabinet's clothing storage space from bottom to top. This drives the discharge of formaldehyde and benzene pollutants accumulated in the wardrobe space, and effectively reduces the humidity inside the wardrobe space, preventing the growth of mold and bacteria on clothing, leather goods, and cabinet wood panels, thereby eliminating blind spots in the freshness and cleanliness of the room.

[0115] When the micro-ventilation structure of the storage subsystem in this embodiment is running, the air duct valves open. Under normal pressure differential conditions, such as when the exhaust module of a whole-house bidirectional fresh air system is pulled out and the return air vent inside the cabinet is at a negative pressure of approximately -70 Pa, this normal pressure differential can pull the main space of the room outside the cabinet by 1 meter. 3 A fresh airflow of / h level flows into the cabinet. The fresh airflow passes through multiple micro-holes for supplying fresh air and multiple micro-holes for discharging stale air, which are vertically arranged and relatively far apart inside the cabinet. The fresh airflow passes through multiple layers of partitions 12 with through holes and / or slots inside the cabinet, slowly releasing and continuously accumulating formaldehyde and benzene pollutants from the various particleboard and plywood that make up the cabinet, and reducing the humidity inside the cabinet to prevent mold.

[0116] In this embodiment, the main fresh air module can adopt an inlet pre-cooling deep dehumidification fresh air module to deliver deeply dehumidified fresh air into the storage space to improve the dryness of the storage space. Specifically, the fresh air module is equipped with a cross-flow heat exchanger, and the two channels of the cross-flow heat exchanger are respectively connected to the second air outlet 102 and the first air outlet 101 of the evaporator. In summer mode, for the high humidity climate of summer during the plum rain season, the high humidity fresh air in the environment is cooled down by the low temperature exhaust air of the finned tube heat exchanger 108 assembly evaporator in the cold fluid channel of the cross-flow heat exchanger, realizing its first heat release and cooling, and "inlet pre-cooling". After "pre-cooling", the sensible heat of the fresh air has been released, the temperature has been significantly reduced, and the relative humidity has been significantly increased, approaching saturation and even releasing some moisture. It then enters the evaporator in a saturated or near-saturated high relative humidity state to realize the second heat release and cooling, that is, the evaporator uses almost all of its cooling capacity to absorb the latent heat of water vapor in the fresh air to achieve "deep dehumidification" of the fresh air. After that, it is injected into the public space.

[0117] The micro-ventilation structure of the storage subsystem in this embodiment sets up a special operating mode for exhausting polluted air from enclosed spaces such as wardrobes, in addition to the winter and summer operation modes of the fresh air conditioning system.

[0118] The micro-ventilation structure of this storage system serves as a parallel bypass for the room's fresh air system. When it operates in the mode of exhausting polluted air from enclosed spaces such as wardrobes, the air valves at the return air vents of all rooms (including public spaces) are closed (if there are pipe valves installed on the micro-ventilation structure, these valves are opened). The operating point of the exhaust fan on the QP diagram moves to the upper left, and the main exhaust system operates and enters a state of high pressure difference and low air volume. The negative pressure generated by connecting the polluted air collection pipes 9 inside each cabinet pulls the formaldehyde and benzene pollutants accumulated in enclosed and hidden spaces such as wardrobes, cabinets, shoe cabinets, and bathroom cabinets through the polluted air collection pipes 9, the main exhaust pipe 5, and the main exhaust module, where they are pressurized and accelerated to be discharged to the outdoor environment.

[0119] The advantages of this embodiment are: ① Eliminates blind spots in the freshness and cleanliness of indoor spaces This embodiment utilizes the combined operation of the intake pre-cooling deep dehumidification fresh air module, air valve, main exhaust duct 5, main exhaust module, and micro-ventilation structures (cabinet exhaust duct 10, waste air collection duct 9, and micro-perforated fresh air inlets 11) in the whole-house bidirectional flow fresh air system. Based on the extremely low leakage rate of the air valve and the high-efficiency exhaust of the centrifugal fan 106 in the exhaust module, a pressure difference significantly greater than that of room fresh air replacement (around 70 Pa) is applied to the micro-ventilation structures in the closed spaces such as wardrobes, cabinets, shoe cabinets, and bathroom cabinets. This drives the discharge of formaldehyde and benzene pollutants stored in the wardrobes and other spaces, and the deep dehumidification fresh air effectively reduces the humidity in the interior spaces of the wardrobes and other spaces, preventing the growth of mold and bacteria on clothing, leather goods, cabinet boards, and other items. It eliminates the blind spots of "freshness" and "cleanliness" in the indoor space, thereby significantly improving the five constant qualities of the indoor space: freshness, cleanliness, quietness, temperature, and humidity.

[0120] ② Provide the most efficient, economical, clean, and reliable fresh air system for building spaces. The radiant cooling surface of the current five constant systems is usually set under the ceiling, which occupies the top space; the fresh air system is to deliver fresh air to each room by laying air supply ducts under the floor and setting fresh air inlets on the floor of each room; such a five constant system fresh air solution not only increases the construction difficulty and cost of fresh air supply ducts, but also makes it easy for pollutants to fall into the second air inlet 102 and to blow up dust on the floor. It also reduces the net height of the space and makes it difficult to find the location of the room's stale air return air inlet and exhaust duct. The fresh air system in this embodiment uses a fresh air module with pre-cooling and deep dehumidification technology as the starting point for whole-house fresh air. It constructs a whole-house fresh air link that starts from and ends in the outdoor environment: "Ambient fresh air → Main fresh air module → Living room corridor public space → Room fresh air inlet → Room main space → Room exhaust duct 3 → Residential unit exhaust duct (main exhaust duct 5) → Main exhaust module → Outdoor atmosphere". It develops the potential of the fresh air supply duct in the living room corridor to implement "ductless air supply". It only needs to set up one exhaust duct, which solves the serious problem of duct space interference between the fresh air supply and waste air return ducts in the ceiling, as well as the problem of the fresh air supply duct competing with the radiant temperature control unit 7 for ceiling and floor surface resources, and the problem of pollutants falling into the second fresh air inlet 102 on the floor and blowing up the floating dust on the ground. It reduces the construction difficulty and cost of the fresh air supply duct, increases the net height of the space, and provides the most efficient, economical, clean and reliable fresh air link system for the whole-house five constant system.

[0121] ③ Provides a wider range of surface source options for radiative cooling. This embodiment only requires one exhaust duct to solve the problem of bidirectional fresh air replacement throughout the house, eliminates the construction difficulty and cost of fresh air supply ducts in traditional five constant systems, increases the net height of the space, provides the most efficient, economical, clean and reliable fresh air link system for the whole house five constant systems, and frees up floor space. In this embodiment, radiant capillary tubes can be laid under the floor for winter heating, providing a wider range of surface source options for radiant cooling and heating. The floor radiant capillary tubes and the ceiling radiant capillary tubes can be used together and complement each other: in summer, ceiling radiant cooling is the main method, and in winter, floor radiant heating is the main method. This combination can bring out the greatest advantages and effects of combining radiant cooling technology with the natural convection of the building space.

[0122] ④ The technological ideal of "defining architecture based on air quality" has been realized. Reinforced concrete technology is the foundational, platform, and prerequisite technology for construction, but only air quality technology is the soul of building technology. This embodiment significantly improves the five-dimensional (five constants) quality of air freshness, cleanliness, quietness, temperature, and humidity in building spaces, transforming building fresh air technology from a supporting role in building structure technology, building material technology, and building process technology into the protagonist and leader of building technology, realizing the technological ideal of "defining buildings with air quality".

[0123] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
