Description

Technical Field

[0001] This invention belongs to the field of fresh air technology, and particularly relates to a sleeve-type sliding air valve, a whole-house fresh air system, and a whole-house five-constant system. Background Technology

[0002] Constructing a single-pipe whole-house five-constant system requires solving the path and structure issues of the whole-house two-way flow fresh air system; installing electric air valves on the exhaust duct to control the return air in each building space and implement fresh air replacement in different areas (rooms) is an important technical direction. For example, a type of air valve (patent number 202210449850.4) is installed in the ceiling of a room as the return air vent of a room in a whole-house bidirectional fresh air system. The space inside the ceiling is connected to the main space of the room through a decorative grille. The opening and closing operation of the air valve provides the whole-house main exhaust system with the option to replace the room with fresh air.

[0003] The aforementioned air valve is a sliding vane type electric air valve, which, compared with the traditional rotary electric air valve, features a simple structure, high reliability, high mechanical strength, and strong resistance to deformation.

[0004] However, the single-pipe whole-house five-constant system is a high-standard system concerning the freshness, quietness, cleanliness, temperature and humidity of the air in the building space. Its "five constant" requirements of constant temperature, constant humidity, constant oxygen, constant cleanliness and constant quietness have set a new benchmark for the organizational structure and operation quality of whole-house fresh air conditioning. Single-pipe whole-house five-constant system places new and rigid requirements on the air valves used for room fresh air replacement, including technical indicators such as no valve seizing during opening and closing, low noise during opening and closing, smooth operation, low ventilation resistance, low leakage rate after shutdown, high reliability and long service life. In addition, after replacing room fan coil units with capillary radiant cooling solutions and eliminating the ceiling used to conceal fan coil units and inlet / outlet duct openings, the inlet / outlet duct openings exposed in the room environment need to have self-decorative appearance indicators. The aforementioned air valves or similar products are difficult to fully meet these requirements. Summary of the Invention

[0031] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a sleeve-type sliding damper, a whole-house fresh air system, and a whole-house five-constant system based on the present invention. The advantages and features of the present invention will become clearer from the following description and claims.

[0032] Example 1 See Figures 1 to 3 In one embodiment, a sleeve-type sliding damper 8 is specifically used in a room with a room exhaust duct 3 installed. The sleeve-type sliding damper 8 includes an outer cylinder 802, an inner cylinder 801, and a drive mechanism.

[0033] The outer cylinder 802 and the inner cylinder 801 are nested together and slide relative to each other, and are configured to slide relative to each other to switch between a closed configuration and a ventilated configuration. The inner cylinder 801 has a ventilation area extending along the sliding direction, and the ventilation area has a plurality of ventilation holes 807. The inner surface of the outer cylinder 802 has a first and a second sleeved area arranged at intervals along the sliding direction. A sealed covering area is formed between the first and second sleeved areas.

[0034] The two ends of the extension 805 are opposite to each other and are respectively connected to the outer cylinder 802. The extension 805 is configured such that its connection point overlaps with the geometric center of the outer cylinder 802 wall (specifically, when the cross-sections of the outer cylinder 802 and the inner cylinder 801 are circular, the extension 805 is connected to the outer cylinder 802 along the diameter; when the cross-section is polygonal, it can be a straight rod passing through the geometric center). The drive mechanism is installed on the inner cylinder 801, and the drive end of the drive mechanism is connected to the connection point. The movement trajectory of the drive end is located at the geometric center of the outer cylinder 802 wall.

[0035] In the closed configuration, the drive end of the drive mechanism moves the outer cylinder 802 to the sealed coverage area, covering the entire ventilation area. In the open configuration, the drive end of the drive mechanism moves the outer cylinder 802 to the sealed coverage area, covering part or not covering the ventilation area.

[0036] Specifically, the ventilation holes 807 on the inner cylinder 801 serve as air inlet channels, and the opening at one end of the inner cylinder 801 can be connected to the room exhaust pipe 3 as an air outlet channel. The inner cylinder 801 may include a first overlapping area, a ventilation area, a second overlapping area, and a dwelling area arranged sequentially along the sliding direction. In the closed configuration, the first fitting area of ​​the outer cylinder 802 moves to the first overlapping area of ​​the inner cylinder 801, and the second fitting area moves to the second overlapping area. The open configuration can be divided into partial opening and full opening. Partial opening means that the second fitting area moves to the dwelling area, and the first fitting area moves to the ventilation area. At this time, the ventilation holes 807 located between the first fitting area and the first overlapping area are open. Full opening means that both the first fitting area and the second fitting area move into the dwelling area. At this time, all ventilation holes 807 are open.

[0037] The specific structure of the sleeve-type sliding damper 8 in this embodiment will be further described below: In this embodiment, both the first and second sleeved areas are provided with flexible sealing sleeves 806. Thus, in the closed configuration, the first sleeved area of ​​the outer cylinder 802 moves to the first overlapping area of ​​the inner cylinder 801, and the second sleeved area moves to the second overlapping area. The ventilation path in the middle is closed by relying on the two flexible sealing sleeves 806, thereby improving the effect of closing the ventilation path.

[0038] In this embodiment, the ventilation holes 807 described above can be arranged in an array along the circumference and sliding direction of the inner cylinder 801 in the ventilation area. Taking the inner cylinder 801 as a cylinder as an example, the ventilation holes 807 can be arranged in an array along the circumferential and axial directions. The ventilation holes 807 can specifically be round holes, square holes, elliptical holes, or other hole shapes, and are not specifically limited here.

[0039] In this embodiment, the inner cylinder 801 is also provided with a strip groove 808 extending along the sliding direction, specifically two opposing straight strip grooves 808. The extension member 805 is configured such that its two ends extend through the strip groove 808 and are connected to the outer cylinder 802. That is, the extension member 805 can slide along the strip groove 808 to drive the outer cylinder 802 to slide.

[0040] In this embodiment, the cross-sectional shape of the inner cylinder 801 and the outer cylinder 802 in the sliding direction is one of the following: triangle, rectangle, grooved rectangle, cylinder, semi-cylindrical, and isosceles trapezoid.

[0041] The inner cylinder 801 and the outer cylinder 802 can be 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.

[0042] In this embodiment, the driving mechanism includes a drive motor 804 and a push rod 803. The drive motor 804 is installed inside the inner cylinder 801, and the push rod 803 is installed at the output end of the drive motor 804. The extension member 805 is vertically connected to the push rod 803. Taking the outer cylinder 802 and the inner cylinder 801 as cylinders as an example, the drive motor 804 drives the push rod 803 to move axially, and then the push rod 803 drives the extension member 805 and the outer cylinder 802 connected to it to move axially.

[0043] In this embodiment, the flexible sealing sleeve 806 may be made of an elastic soft material.

[0044] When the sleeve-type sliding air valve 8 of this embodiment is opened, the push rod 803 of the drive motor 804 pushes the outer cylinder 802 to slide on the outer surface of the inner cylinder 801. The outer cylinder 802 partially or entirely slides to the dwelling area, and the ventilation holes 807 on the wall of the inner cylinder 801 are partially or completely exposed to the room air. Under the suction of the external exhaust module and exhaust pipe, the room stale air flows into the room exhaust pipe 3 through the exposed ventilation holes 807 area of ​​the inner cylinder 801, and the fresh air outside the room is then replenished into the room to implement room fresh air replacement. When the sleeve-type sliding damper 8 is closed, the drive motor 804 pushes the push rod 803 to push the outer cylinder 802 to slide on the outer surface of the inner cylinder 801. The outer cylinder 802 slides out of the dwelling area as a whole. The first sleeve area covers the first overlapping area, the second sleeve area covers the second overlapping area, and the ventilation hole 807 area on the wall of the inner cylinder 801 is completely covered by the cylinder wall of the outer cylinder 802. The damper is closed and the fresh air replacement process of the room is completed.

[0045] The advantages of the sleeve-type sliding damper 8 in this embodiment are as follows: ① The air valve opens and closes smoothly. In one embodiment of the present invention, the outer cylinder 802 and the inner cylinder 801 are configured to be sleeved and slidably connected, the extension member 805 is configured to be connected to the outer cylinder 802 at two points, and the connection point between the drive end of the drive mechanism and the extension member 805 is set at the geometric center of the outer cylinder 802 wall. The movement trajectory of the drive end is also kept at the geometric center of the outer cylinder 802 wall. This makes the thrust and torque of the extension member 805 on the outer cylinder 802 symmetrical and balanced, and the opening and closing operation of the outer cylinder 802 on the inner cylinder 801 is smooth, eliminating the risk of the outer cylinder 802 seizing up and the air valve being difficult to open and close normally.

[0046] ② The air leakage rate is almost zero. In one embodiment of the present invention, when the sleeve-type sliding air valve 8 is in the closed configuration, the outer cylinder 802 moves to the sealing coverage area to cover the entire ventilation area. That is, the two flexible sealing sleeves 806 are respectively located on both sides of the ventilation area. The air valve is closed by the two flexible sealing sleeves 806 in conjunction with the solid part of the inner cylinder 801. The flexible sealing sleeves 806 are made of flexible material. After the air valve is closed, under the pressure difference between the external environment of the air valve and the inner side of the inner cylinder 801, the flexible sealing sleeves 806 can stick tightly to the inner cylinder 801, completely eliminating the risk of air leakage after the air valve is closed. The air leakage rate of the air valve is almost zero.

[0047] ③ Possesses self-decorative properties In one embodiment of the present invention, the sleeve-type sliding air valve 8, considering that the five constant systems adopt a capillary radiant cooling scheme to replace the room fan coil unit, and eliminates the ceiling used to conceal the fan coil unit and the inlet and outlet air duct openings, and the inlet and outlet air duct openings of the fan are exposed in the room environment and need to have self-decorative properties, the end face of the inner cylinder 801 and the outer cylinder 802 of the air valve can adopt a grooved rectangular or semi-cylindrical structure, which has the advantage of self-decorative properties. It can adopt a hollow structure of various colors, and even set a sound unit 13 on the air valve, so as to implement self-decorative decoration of the air valve with different colors, materials and processes.

[0048] Example 2 See Figure 4 This embodiment provides a sleeve-type sliding air valve 8 based on the above embodiment one. The specific difference is that the outer cylinder 802 and the inner cylinder 801 of this embodiment are both semi-cylindrical, and the extension 805 is configured to be connected at one end to the midpoint of the bottom edge of the semi-circular cross-section of the outer cylinder 802 and perpendicular to the bottom edge.

[0049] In this embodiment, because the inner cylinder 801 and outer cylinder 802 of the air valve adopt a semi-cylindrical structure, it is more suitable for application scenarios where the suspended ceiling has been removed. The semi-cylindrical air valve is installed on the side wall of the room and suspended. Furthermore, it is especially suitable for opening and closing at the end of the air duct for negative pressure suction.

[0050] Example 3 See Figure 5 , Figure 16 and Figure 17 Based on the above embodiments one and two, this embodiment provides a sleeve-type sliding air valve 8 for installation in a room with a fresh air duct 15. The sleeve-type sliding air valve 8 also includes an outer cylinder 802, an inner cylinder 801 and a driving mechanism. The difference is that the outer cylinder 802 is fixed and the inner cylinder 801 is movable.

[0051] The outer cylinder 802 and the inner cylinder 801 are nested together and slide relative to each other, and are configured to switch between a closed configuration and a ventilated configuration. The outer cylinder 802 has a ventilation area extending along the sliding direction, and the ventilation area has several ventilation holes 807. The outer surface of the inner cylinder 801 has a first and a second sleeved area arranged at intervals along the sliding direction, and both the first and second sleeved areas are provided with flexible sealing sleeves 806. A sealed covering area is formed between the first and second sleeved areas. A drive mechanism is mounted on the outer cylinder 802, and the drive end of the drive mechanism is connected to the inner cylinder 801 via an extension 805. The movement trajectory of the drive end is located at the geometric center of the outer cylinder 802 wall.

[0052] In the closed configuration, the drive end of the drive mechanism moves the inner cylinder 801 to the sealed coverage area, covering the entire ventilation area. In the open configuration, the drive end of the drive mechanism moves the inner cylinder 801 to the sealed coverage area, covering part or not covering the ventilation area.

[0053] Specifically, the ventilation holes 807 on the outer cylinder 802 serve as air inlet channels, and the opening at one end of the outer cylinder 802 can be connected to the room exhaust pipe 3 to serve as an air outlet channel. The outer cylinder 802 may include a first overlapping area, a ventilation area, a second overlapping area, and a dwelling area arranged sequentially along the sliding direction. In the closed configuration, the first sleeve area of ​​the inner cylinder 801 moves to the first overlapping area of ​​the outer cylinder 802, and the second sleeve area moves to the second overlapping area. The air passage in the ventilation area located in the middle is closed by relying on two flexible sealing sleeves 806. The open configuration can be specifically divided into partial opening and full opening. Partial opening means that the second sleeve area of ​​the inner cylinder 801 moves to the dwelling area, and the first sleeve area of ​​the inner cylinder 801 moves to the ventilation area. At this time, the ventilation holes 807 located between the first sleeve area and the first overlapping area are open. Full opening means that both the first sleeve area and the second sleeve area of ​​the inner cylinder 801 move into the dwelling area. At this time, all ventilation holes 807 are open.

[0054] Furthermore, the inner cylinder 801 and outer cylinder 802 of this embodiment can adopt the semi-cylindrical shape of the above embodiment 2, which is more suitable for application scenarios where the suspended ceiling is removed. The semi-cylindrical structure of the air valve is set on the side wall of the room and suspended. In addition, since the outer cylinder 802 of the electric air valve is fixed and the inner cylinder 801 slides along the inner wall of the outer cylinder 802 under the drive of the electric push rod 803, it is especially suitable for the opening and closing of the end of the positive pressure air supply airway.

[0055] Example 4 This embodiment provides a whole-house fresh air system for a group of rooms, which includes multiple rooms and a public space connected to each room. The whole-house fresh air system includes the sleeve-type sliding air valve 8, the single-pass bidirectional flow whole-house fresh air system, and the room fresh air duct as described in Embodiment 1 or Embodiment 2 above.

[0056] A 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 stale air return ends 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.

[0057] The fresh air ducts in the rooms correspond one-to-one with the return air ducts in the rooms. The fresh air ducts are configured to connect the public space and the rooms to form a fresh air relay channel.

[0058] The sleeve-type sliding air valves 8 are installed at the corresponding room's waste air return air end, and are controlled to open or close by the sleeve-type sliding air valves 8.

[0059] See Figure 18 In this embodiment, the room's fresh air duct is a vertical air duct 1. The 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 and are connected by an air duct channel formed by the inner wall of the vertical air duct 1. The air duct channel is used to dissipate sound wave transmission between the public space and the room. The vertical air duct 1 can be a passive vertical air duct or an active vertical air duct.

[0060] The passive vertical duct includes a first air vent 101 facing the public space and a second air vent 102 facing the room. The first air vent 101 and the second air vent 102 are arranged vertically away from each other (the first air vent 101 is the air inlet, and the second air vent 102 is the air outlet; specifically, the first air vent 101 can be located at the lower end and the second air vent 102 at the upper end, or the first air vent 101 can be located at the upper end and the second air vent 102 at the upper end) and are connected by a duct flow channel formed by the inner wall of the passive vertical duct. The purpose of arranging them far apart is to maximize the distance that sound waves travel within the passive vertical duct for attenuation. The vertical distance between the first air vent 101 and the second air vent 102 is greater than half the room height. The first air vent 101, the second air vent 102, and the air duct flow channel form a bent delivery channel. The bent area of ​​the bent delivery channel is used to slow down the transmission of sound waves and form a fresh air replacement and conduction node between the public space and the room, so that the public space and the room can achieve air circulation and maintain quietness when the door 6 is not opened.

[0061] During operation, the exhaust single-pipe bidirectional flow fresh air replacement system injects fresh air into the living room corridor (public space), establishing a slight positive pressure in the corridor, and extracts stale air from each room, establishing a negative pressure state in each room. This creates a pressure difference between the first air outlet 101 and the second air outlet 102 of the passive 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 duct 1, rushing into the room space at a certain speed and direction angle, driving the stale air in the room into the return air duct, thus achieving fresh air replacement in the room.

[0062] The active vertical duct is based on the passive vertical duct. It has a relay power point (centrifugal fan) set in the duct channel. It 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 (that is, the relay power point further pulls fresh air from the public space into the room). 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, 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 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.

[0063] 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.

[0064] 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 into the environment under positive pressure to establish a fresh air supply in the public space. The main exhaust air module is connected to the exhaust ducts 3 of each room via the main exhaust duct 5, and the sleeve-type sliding dampers 8 are respectively installed at the end of each room's exhaust duct 3 that extends into the room. The main fresh air module is the positive pressure power point mentioned above, and the main exhaust air module is the negative pressure power point mentioned above.

[0065] 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.

[0066] The main exhaust module forms a room exhaust return air end in the corresponding room through the main exhaust duct 5 and the room exhaust ducts 3. The room exhaust return air end 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.

[0067] Example 5 This embodiment, based on the above embodiments, adds a speaker unit 13 to the sleeve-type sliding damper 8. Specifically, the outer cylinder 802 and inner cylinder 801 of the sleeve-type sliding damper 8 cooperate to form a mounting groove extending along the sliding direction, and the speaker unit 13 is integrated within the mounting groove. For example, when the outer cylinder 802 and inner cylinder 801 are rectangular or semi-circular, the surfaces of the outer cylinder 802 and inner cylinder 801 facing the room can be recessed inward to form the aforementioned mounting groove, and the speaker unit 13 is directly installed within this mounting groove.

[0068] A speaker can be attached to the second vent 102 of either the active or passive vertical duct. This speaker can be a columnar structure embedded in the exhaust vent, with the actual return air area of ​​the exhaust vent located on both sides of the columnar speaker. The speaker's appearance on the lower indoor side of the vertical duct 1 can be the same as the speaker structure of the first vent 101, or it can be similar in color to the doorpost. By installing decorative speakers at three points—the second air vent 102 of the whole-house fresh air system, the sleeve-type sliding air valve 8, and the bottom of the active / passive vertical air duct on the indoor side—they not only serve a decorative purpose on the structure of the second air vent 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.

[0069] Example 6 See Figure 15 and Figure 19 Based on Embodiment 3 above, this embodiment provides a whole-house fresh air system. The difference is that the single-pipe bidirectional flow whole-house fresh air system has been adjusted. Specifically, the whole-house fresh air system is changed from a single-pipe bidirectional flow whole-house fresh air system with ductless air supply to public spaces and return air to rooms to a single-pipe 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.

[0070] The whole-house fresh air system is also used in room groups, which include 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 / passive vertical air duct.

[0071] 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.

[0072] Active / passive vertical air ducts are arranged in the corresponding rooms, corresponding to the fresh air supply terminals of the rooms. The specific structure of the active / passive vertical air ducts is the same as that in the above embodiments.

[0073] The aforementioned sleeve-type sliding air valve 8 is installed at the corresponding room's fresh air supply end.

[0074] 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.

[0075] 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 sleeve-type sliding damper 8 is installed at the end of the fresh air duct 15 that extends into the room. The main fresh air module is the positive pressure power point, and the main exhaust module is the negative pressure power point.

[0076] 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 1616 located in the public space to establish a negative pressure extraction state in the public space.

[0077] 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 / passive vertical duct) → Living room corridor public space → Main exhaust module → Outdoor ambient air".

[0078] 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.

[0079] 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 / passive vertical duct, 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 four important nodes: the main fresh air module, the room fresh air inlet, the active / passive vertical duct (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 / passive vertical duct (room return air inlet).

[0080] 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. The total heat exchanger exchanges sensible and latent heat between the fresh and return air. The finned tube heat exchanger is connected to the refrigerant circuit of the air conditioning unit to further cool and dehumidify (heat up) the fresh air flow. 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 on 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.

[0081] 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.

[0082] 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.

[0083] In this embodiment, the room return air vent can be an active / passive vertical air duct set on the side of the room door 6. For specific structure, please refer to the above embodiments.

[0084] When the vertical duct 1 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 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.

[0085] 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 supplied from the return air vents 16 of each room and public space into the atmosphere. This embodiment uses a main exhaust module driven by a backward centrifugal fan. This main exhaust module is combined with the main fresh air module to form an integrated main air intake and exhaust module 4 with a total heat exchanger as the core.

[0086] 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 / passive vertical air duct 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 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 / passive vertical air duct) → Living room corridor public space → Main exhaust air module of main air intake and exhaust module 4 → Outdoor ambient atmosphere".

[0087] 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".

[0088] 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.

[0089] In this embodiment, the vertical air duct 1 in the room fresh air system serves as an airflow channel connecting the room and the public space. Its structural features, with its 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.

[0090] 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.

[0091] 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 opening, not to expand the vertical space of the ceiling where the supply and exhaust ducts 401 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.

[0092] Example 7 See Figures 7 to 9This 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 in the above embodiment.

[0093] This embodiment employs a whole-house five-constant system that introduces fresh air into the room through a vertical duct 1, based on the following analysis and judgment regarding the indoor air quality indicators, their status, and significance: In an era where air quality defines buildings, 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 of air quality in building spaces will be improved, thus achieving "five constants" and becoming "five constant systems".

[0094] 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 exhaust duct (main exhaust module, main exhaust pipe 5, room exhaust pipe 3) is set up to replace the two sets of traditional supply air pipe 401 exhaust pipe to implement a "ductless 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.

[0095] 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.

[0096] 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 uses active / passive vertical air ducts as the core node to construct a whole-house bidirectional flow fresh air link that starts from the outdoor environment and ends at the outdoor environment, with two air path power points: "Ambient fresh air → main fresh air module → living room corridor public space → room vertical air duct 1 → main room space → room exhaust duct 3 → residential unit exhaust duct (main exhaust duct 5) → main exhaust duct module → outdoor atmosphere".

[0097] 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, inlet and outlet air chambers and exhaust pipes, 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.

[0098] The main air intake and exhaust module 4 uses a dual-fan unit for fresh air intake and exhaust of polluted air, a dual-channel total heat exchanger core, and a finned tube heat exchanger 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, is cooled and dehumidified by the polluted air flow, and then enters 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 polluted air flow, and then enters the finned tube condenser for reheating. Finally, it is pressurized by the fresh air fan and sent into the interior space.

[0099] 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.

[0100] 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 jointly establish a pressure difference between the first air outlet 101 and the second air outlet 102 of the vertical air duct 1. Driven by this pressure difference, the fresh air in the living room corridor flows from bottom to top through the vertical air duct 1 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.

[0101] 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).

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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 / passive vertical air duct in the fresh air system serves as an airflow channel connecting the room and the public space. The staggered and opposite arrangement of the first air outlet 101 and the second air outlet 102 not only promotes the two-dimensional movement of the fresh air flow on the horizontal plane in shaping the airflow field of the room and the public space, but also drives the vertical flow of the fresh air flow 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 air flow in the interior space, eliminates blind spots in fresh air replacement, and improves the efficiency of fresh air replacement.

[0106] The fresh air system in this embodiment uses an active / passive vertical duct 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 → 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 has developed the potential of the air supply duct 401 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.

[0107] 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. 3Even 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.

[0108] 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.

[0109] 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.

[0110] 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".

[0111] Example 8 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.

[0112] 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.

[0113] See Figures 11 to 14 Therefore, this embodiment provides a whole-house five-constant system based on the above embodiments. 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.

[0114] 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.

[0115] This embodiment adopts a micro-ventilation structure for residential storage systems such as wardrobes, cabinets, shoe cabinets, and bathroom cabinets. This includes a partition 12 with through holes and / or slits inside the cabinet, and vertically arranged slits or multiple micro-holes for supplying fresh air and slits or multiple micro-holes for discharging stale air.

[0116] 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 duct valve may also be provided; the waste air collection pipe 9 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 9 connects... The exhaust duct of the residential unit (i.e., the main exhaust duct 5, which opens synchronously if a duct valve is installed) is connected to the air duct of the cabinet (i.e., the main exhaust duct 5). Under the negative pressure generated by the return air vent 901 of the cabinet in the dirty air collection duct 9, the dry airflow in the indoor space is driven from bottom to top through the multiple layers of perforated and / or slit partitions 12 in the clothing storage space inside the cabinet. 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 boards, thereby eliminating the wardrobe blind spot in terms of freshness and cleanliness in the room.

[0117] 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.

[0118] 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 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.

[0119] 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.

[0120] 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.

[0121] 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 and 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 a 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 in the exhaust module, a pressure difference (approximately 70 Pa) significantly greater than the room's fresh air replacement 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 inside the wardrobes and other spaces, preventing the growth of mold and bacteria on clothing, leather goods, cabinet boards, and other items. It eliminates blind spots in the "freshness" and "cleanliness" of the indoor space, thereby significantly improving the five constant qualities of the indoor space: air freshness, cleanliness, quietness, temperature, and humidity.

[0122] 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.

[0123] 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.
