Description
Technical Field
The invention belongs to a room group ventilation system, and particularly relates to a bidirectional flow full-house fresh air system.
Background
Air, which is a vital element that our human beings cannot leave every minute of every living body, depends on air more than all other vital elements, including food and water. Most of the life of a person is living in a house, essentially in an indoor secondary air environment surrounded by a house wall and a floor. Carbon dioxide and excrement generated by human metabolism, oil smoke flowing out of kitchen cooking, water vapor evaporating out of bath, benzene and formaldehyde volatilized by indoor decoration materials and the like, so that indoor air is polluted, and great demands of people on house ventilation and improvement on indoor secondary environment quality are released.
Our living space requires continuous stable high quality fresh air replacement, but residential ventilation is not equal to opening doors and windows. In summer in winter when quality indexes such as air temperature and humidity deviate from normal values, in climatic periods such as haze days, sand wind days, return to the south, plum rains and the like, in windless periods when the atmosphere is in a static state, and epidemic prevention periods when the indoor ventilation quantity needs to be increased by viruses, mechanical ventilation equipment is needed to carry out concentrated filtration, cooling and dehumidification (heating and temperature rise) treatment on fresh air, fresh air flow with proper temperature, humidity, cleanliness and freshness is input, the quality of secondary environment in a sleeve is improved, and living ideal which is derived from nature and is achieved.
However, in order to meet the fresh air demand of the house, the simple fresh air system assembled on the new building tray is mainly a PVC air supply pipeline used for communicating all rooms on an air supply fan module and a suspended ceiling, and is a blind-intestine type one-way flow, and the system has no actual effect of synchronous running of fresh air pressurization feeding and dirty air negative pressure collecting and discharging, and has the advantages of high processing precision and good air tightness of the existing doors and windows, and no exit of the doors and windows of the room due to the fact that the fresh air cannot be discharged when the doors and windows of the room are opened and the dirty air is matched, and the fresh air cannot be fed. The blind-intestine type unidirectional flow fresh air system in the current building is deviated from the basic principles of three-section type ventilation and bidirectional flow, so that the problems that the room polluted air cannot be discharged and the fresh air cannot be sent in, and the inner wall of the fresh air supply pipe is condensed with dust bacteria microorganisms to form a culture medium to cause secondary pollution are caused.
In fact, in the house design and construction process, the inner wall, the outer wall and the doors and windows divide the originally spacious complete house space into a plurality of functional units such as living rooms, bedrooms, study rooms, kitchens, toilets and storage rooms, and the functional space units are difficult to achieve natural ventilation with outdoor environments and even difficult to operate even forced ventilation.
The basic properties of the low-rise, multi-inner wall and small unit space are different from European villas, the design starting point of the mechanical ventilation system of the Chinese resident is that two sets of pipelines for fresh air feeding and waste air discharging cannot be installed under the condition of 3000mm of the current layer height, the building area for reducing the layer height by 10% from 300mm to 3300mm is not commercially possible, and the cost is difficult to digest because two sets of pipelines for bidirectional flow and exhaust, a fresh air module and an exhaust module are additionally arranged, and the suspended ceiling area is additionally arranged by decorating the two sets of pipelines.
Meanwhile, in the overall planning and design of the residential fresh air system, the problems of residential fresh air replacement and air conditioning energy consumption directly related to fresh air replacement are not only solved to improve the quality of secondary environments in a sleeve, but also the energy consumption of ventilation engineering per se must be concerned, and the ventilation and air conditioning energy consumption becomes a main body of building energy consumption.
The building energy consumption (about 10 hundred million tons of standard coal equivalent) in China has been 22% in total social energy consumption, and is parallel to industrial energy consumption and traffic energy consumption, so that the building energy consumption is three-sisal of total social energy consumption, and the building energy consumption are further improved due to improvement of resident living conditions and urban updating, so that the building energy consumption and the building energy consumption are the focus of carbon-to-carbon neutralization in the peaks of China and the world.
In recent years, the development of building energy-saving technology is extremely rapid, diversified and general in forests, but the technology can be classified into three types of building material energy saving, equipment process energy saving and building structure energy saving:
① The building materials are energy-saving, for example, hollow bricks and foaming cement bricks are adopted to build the wall, rock wool boards and polyurethane foaming boards are adopted to pave the outer wall surface of the building, and the heat insulation performance of the hollow bricks, the foaming cement bricks, the rock wool and the polyurethane foaming boards is utilized to block the heat transmission inside and outside the wall so as to reduce the energy consumption of the building;
② The equipment and process type energy conservation, for example, a residential air conditioner adopts a temperature and humidity independent regulation mode, and the indoor temperature is properly increased under the condition of reducing the indoor relative humidity and maintaining the body feeling comfort level so as to reduce the indoor and outdoor temperature difference and reduce the heat leakage and the energy consumption of the air conditioner;
③ The energy-saving structure adopts a heat-insulating bridge aluminum alloy door and window, an insulating nylon connecting piece is embedded between an inner aluminum alloy frame and an outer aluminum alloy frame to block heat conduction between the inner aluminum alloy frame and the outer aluminum alloy frame, so that the point type residence is reduced, the strip type residence structure design is promoted greatly, the outer wall surface area and the specific surface area of the residence building are reduced, the energy exchange intensity inside and outside the residence is reduced, the energy consumption is reduced, and the like, and the structural energy saving of the building is realized through the optimization of the building structure or the building part structure;
Among the three types of building energy-saving technologies, the first type of wall heat preservation and hollow glass and other building material energy-saving technologies have been widely applied to obtain very excellent technical effects, the space for improving the energy-saving effect by continuously improving the heat insulation performance and thickness of the building material is very narrow, the second type of residential energy equipment is technically energy-saving, the technology is relatively complex, the residential energy equipment such as an elevator, an air conditioner, a water heater and a kitchen range is taken as the representative of 'Chinese building' through the hard effort of Chinese engineers, the energy-saving level of the residential energy equipment is already world-first, the third type of structural energy saving is realized, the area and the specific surface area of the outer wall of the residential building are reduced through the optimization of the building structure, the indoor and outdoor heat transfer temperature difference is reduced through the optimization of the spatial relationship of building parts, and the building space is greatly improved.
The method takes the basic attributes of low-rise, multi-inner wall and small unit space of the resident house of China as the starting point, focuses on the problems of path, power and efficiency of fresh air replacement and ventilation and building energy conservation, effectively solves the two problems of fresh air replacement and building energy conservation through the optimization of building parts, particularly electromechanical parts and building relations, and is a great mission and a difficult task of the real estate industry, the building design industry and the fresh air conditioner industry.

The whole-house fresh air system provided by the embodiment is an integrated innovation based on the room fresh air system arranged on the adjacent outer wall of the room fan coil, and has quite clear technical and economic comparison advantages:

The embodiment adopts a full-house bidirectional flow fresh air conditioning system, and links 'environment fresh air → fresh air module → living room passageway replacing air supply pipes → fresh air port of each room → room fan coil → inner wall → room return air pipe → central air pipe → exhaust fan → environment atmosphere' to form a very optimized fresh air replacement path, and the fresh air replacement path is linked to form a complete air supply and exhaust bidirectional flow airflow organization form comprising three stages of supply, replacement and exhaust. In spring and autumn with proper ambient air cleanliness and temperature and humidity, the novel air module can be short-circuited, and the novel air directly enters the corridor from the balcony screen door through the living room and then turns into the room, so that the flow is simplified.
A full-house bidirectional flow fresh air conditioning system is characterized in that a house ventilation main path which mainly comprises feeding, replacement and discharging is connected with a house air path which is formed by a house fresh air inlet, a fan coil, an inner wall and a house return air pipe of each house in parallel, so that the problem of the old and difficult short circuit of the house fresh air is solved, all the houses in the house comprise a bathroom and enjoy the fresh air replacement of 'large water flood filling', and the full-house fresh air replacement has no blind area and dead angle.
2. Fully compatible fresh air replacement power
The whole-house bidirectional flow fresh air conditioner integrated system of the embodiment is based on the current household central air conditioner system, and the potential of a room fan coil is explored to serve as the power of a whole-house total fresh air module and the relay power of room fresh air.
The combined fresh air module is arranged in a living room and is compatible for two times, because the fresh air fan coil is installed close to a balcony door from the deep part of the traditional living room, the structural inversion of a living room temperature field realizes transition energy conservation, thereby bringing about reduction of the heat load of the living room, 2 fresh air fan coils (originally split into 2 for noise reduction) in the traditional living room are combined into 1, then the air conditioning treatment of the fresh air fed by a balcony air inlet booster device is combined with the circulating function in the living room again, and the same-machine air conditioning is implemented. After the fresh air module and the fan coil are subjected to 2 times of functional recombination and 1 time of space recombination to form the combined fresh air module, the cost of living room fresh air conditioning equipment and the cost of installation and operation are reduced compared with those of the traditional double fan coils.
The room fresh air system sets a room fan coil as relay power for room fresh air replacement on the premise of not increasing an independent air supply pipeline and power equipment, a room fresh air electric air door is arranged on a room door leaf (or above a door frame), an induced draft opening secondary negative pressure function of the room fan coil during running is developed on the basis of primary negative pressure of a room generated by exhausting waste air between rooms by a whole room exhaust system, the induced draft opening of the fan coil becomes a room lowest air pressure area, the biggest pressure difference generated inside and outside the door leaf electric air door pulls aisle fresh air to flow into the room, the air is blocked by the fan coil to return to a room main space by 'attractive force slingshot', the room main space is blocked by the inner wall, the waste air is driven to flow into a fan return air opening, the problem of room fresh air short circuit is solved, the fresh air replacement power is fully compatible with internal circulation air conditioning power, and the potential of the room fan coil is deeply developed.
3. Fine fresh air replacement efficiency
When the whole-room bidirectional flow fresh air conditioning system performs fresh air replacement, the introduced outdoor fresh air is firstly filtered in an air inlet boosting device, then enters a living room large-size fresh air fan coil (more than FP 102) for air conditioning modulation, and comprises the steps of cooling and dehumidifying in summer, heating and heating in winter, and sending high-quality fresh air reaching the standards of freshness, cleanliness and temperature and humidity into living room channels in a sleeve to directly prop against the door heads of each room;
When the room fresh air is replaced, in order to reduce the mixing of the room fresh air and the polluted air, reduce the wind age of the room, implement the time-staggered fresh air replacement of the separated rooms, so as to increase the air quantity of the room in the fresh air replacement state, enable the air quantity to approach the running air quantity of the room fan coil at a low speed gear, reduce the partial internal circulation air quantity possibly existing in the fan coil during the room fresh air replacement, and enable the fresh air ejected by the gravity slingshot of the room fan coil to be pushed to the inner wall in a laminar flow mode and then folded to the return air inlet, thereby improving the room fresh air replacement efficiency.
The central air duct exhaust system is arranged above the corridor, and is used for accommodating the dirty air of the return air ducts of each room from two ends, flowing to the waist air outlet and then flowing through 2 small-diameter beam penetrating air ducts to be sent to an exhaust fan, and the air ducts are connected in parallel to form a network, so that the sectional area of the air ducts is enlarged, the flow speed is reduced, the resistance is reduced, and the exhaust energy consumption and the noise are greatly reduced.
The embodiment adopts a three-level link conveying mode of ' fresh air positive pressure feeding + fan coil gravity slingshot + dirty air negative pressure pumping ', and measures and calculates according to ' 1-day 4 fresh air replacement, 45min each time and 400m3 full-scale scanning replacement of ventilation quantity ' of a large household ' 1, wherein a fresh air module and an exhaust module adopt outer rotor centrifugal fans YWF-B2S-220-065AB00,540m 3/h and power 80w, living rooms and room fan coils respectively adopt FP102 and FP51, replacement air quantity respectively selects 540 and 270m 3/h, motor power is respectively 54 and 98w, 2 room fan coils are simultaneously operated when the fresh air partition replacement in the cover is executed, the total power of the fan is 2×80+2×54+1×98=366 w, 4 times total 3 hours in the whole day is operated, 24-hour average value 45.75w and the total power consumption of fresh air is 1.1kwh (excluding the energy consumption of a host machine operation). Compared with air conditioning (heating) load of about 15kw and 5kw power load of an air conditioning (heat pump) host in winter and summer, the energy consumption average value of the full-house bidirectional flow fresh air replacement is lower by 2 orders of magnitude, and the energy consumption is also greatly lower than the energy-saving building energy consumption caused by the transition of a living room fan coil, and can be ignored.
4. Super-large building energy-saving
The full-house bidirectional flow fresh air conditioning system of the embodiment has the advantages that all functions of an air conditioner are continued, a traditional deep room setting mode of a room fan coil is innovatively set to a position adjacent to an outer wall, novel structural relation between an air conditioner and a building is innovated, indoor temperature field distribution is changed, and temperature difference delta T between the inner side and the outer side of the outer wall is reduced, so that indoor and outdoor heat exchange strength Q and building energy consumption are reduced.
Because the air-conditioning heating energy consumption is basically derived from heat exchange inside and outside a building, the heat exchange inside and outside the building involves 3 heat exchange stages of indoor side air convection, outer wall heat conduction and outdoor side air convection, so that the calculation and control of the heat exchange inside and outside the building are very complex, but the calculation and control of the heat exchange inside and outside the building are further complex in summer winter, in the formula of Q (heat exchange intensity) =K (total heat transfer coefficient) ×S (outer wall area) × (inner and outer wall temperature difference) T (outer wall area) × (outer wall temperature difference), only the component factors and interrelationships of K are complex, and the structural complexity and the calculation complexity of K do not change the simple mathematical relationship that the heat exchange intensity Q is in direct proportion to the outer wall area S and the outer wall inner and outer wall temperature difference T.
In the traditional air conditioner installation engineering, a room fan coil is usually arranged at the deep part of a room relative to an outer wall, and in the case of refrigerating operation under the standard working condition of an air conditioner in summer, the room fan coil arranged at the deep part of the room is sucked into a room return air at about 27 ℃ to cool and dehumidify, then cold air flow at about 14 ℃ after cooling and dehumidification passes through the upper space of the room and is blown to the outer wall, the cold air flow is blocked and reflected by the outer wall, and flows back to the lower part of the room fan coil from the middle lower space of the room to the deep part of the room, and is sucked into the room fan coil again to cool and dehumidify by the room fan coil to start a new cycle.

Example 2
In this embodiment, a second room fan coil 10 is added to the second room 4, and referring to fig. 9 to 13, the second room fan coil 10 is disposed in the room body 401 and is located on the outer wall 4012 of the room body 401 or adjacent to the outer wall 4012. The air outlet of the second room fan coil 10 faces to the deep part of the room body 401, the external wall 4012 is located at the shallow part of the room body 401, and the deep part of the room body 401 is opposite to the external wall 4012.
The exterior wall 4012 of the present embodiment includes at least one of a solid exterior wall, a hollow exterior wall, a foam exterior wall, and an exterior wall provided with an exterior window. And when the circulation in the second room 4 is executed, the second room fan coil 10 reverses the room temperature field constructed when the traditional fan coil is arranged close to the inner wall, so that a brand new second room temperature field space structure is formed.
When the second room fan coil 10 circulates, under the action of the fan of the second room fan coil 10, the air in the room body 401 enters the second room fan coil 10 from the air suction inlet of the second room fan coil 10, and is discharged into the room body 401 through the air outlet of the second room fan coil 10.
The first room fan coil 7 and the second room fan coil 10 are arranged adjacent to the outer wall, and are judged based on the analysis of building physics that air conditioning and heating energy consumption in summer and winter is the main body of building energy consumption, the air conditioning heating energy consumption is essentially generated by heat exchange inside and outside the building, and the heat exchange inside and outside the building relates to 3 heat exchange stages of indoor side air convection, outer wall heat conduction and outdoor side air convection, so that the calculation and control of the heat exchange inside and outside the building are very complex.
The heat exchange power Q 1 of the environment atmosphere and the indoor space is equal to K, the total heat transfer coefficient inside and outside the outer wall body is equal to K, the surface area S of the outer wall body is equal to delta T of the heat transfer inside and outside the wall body;
The calculation formula of the total heat transfer coefficient K inside and outside the wall body is as follows:
Wherein, alpha 1 is the air heat transfer coefficient of the outer side of the wall body, alpha 2 is the air heat transfer coefficient of the inner side of the wall body, b is the thickness of the wall body, and lambda is the heat transfer coefficient of the wall body.
Referring to fig. 14, the middle part in fig. 14 is an outer wall, the left side is an external environment, the right side is an indoor space, and when the ambient air temperature is higher than the indoor temperature, the outdoor heat is transferred to the indoor by three-stage relay along the heat flow direction in fig. 14:
1. convection heat exchange area for hot air outside outer wall body
The first section is an external hot air convection heat transfer area of the external wall, the convection heat transfer coefficient is alpha 1, the hot air forms a laminar flow bottom layer F 1-F1 near the wall surface of the external wall, and the hot air leaks heat to the laminar flow bottom layer F 1-F1 through convection.
2. External wall heat conduction
The second section is wall heat conduction, the thickness of the wall is b, the heat conduction coefficient is lambda, and the heat of the external hot air laminar flow bottom layer F 1-F1 is conducted to the indoor cold air laminar flow bottom layer F 2-F2 through the wall in a heat conduction mode;
3. Indoor cold air convection heat exchange area
The third section is an indoor cold air convection area, the convection heat transfer coefficient is alpha 2, the cold air forms a laminar flow bottom layer F 2-F2 near the inner surface of the outer wall body, and the laminar flow bottom layer F 2-F2 transfers heat leakage to the deep space of the room through indoor cold air convection.
When the ambient atmospheric temperature is lower than the indoor temperature, heat is transferred from the indoor to the outdoor along the three-section relay in the heat flow direction, and the heat exchange principle is the same as that of the heat exchange between the inside and outside of the building, and the heat flow direction is opposite to that of the heat exchange between the inside and outside of the building:
1. indoor hot air convection heat exchange area
The first section is an indoor hot air convection area, the convection heat transfer coefficient is alpha 2, the hot air forms a laminar flow bottom layer F 2-F2 near the inner surface of the outer wall body, and the indoor hot air leaks heat to the laminar flow bottom layer F 2-F2 through convection.
2. External wall heat conduction
The second section is the heat conduction of the wall body, the thickness of the wall body is b, the heat conduction coefficient is lambda, and the heat of the indoor hot air laminar flow bottom layer F 2-F2 on the inner wall surface of the wall body is conducted to the cold air laminar flow bottom layer F 1-F1 on the outer wall surface in a heat conduction mode;
3. External cold air convection heat exchange area of external wall body
The third section is an external wall external cold air convection heat transfer area, the convection heat transfer coefficient is alpha 1, the cold air forms a laminar flow bottom layer F 1-F1 near the external wall surface of the external wall, and the laminar flow bottom layer F 1-F1 transfers the heat leakage from the indoor to a far place through cold air convection.
Although the three-stage heat leakage process of the outdoor hot air from the outside wall to the indoor through the outside wall or the indoor hot air from the outside wall to the outdoor through the outside wall in winter is complex, in the formula of Q (heat exchange intensity) =k (total heat transfer coefficient) ×s (outside wall area) ×× T (inside and outside temperature difference), only the component factors and interrelationships of K are complex, and the mathematical structure complexity and the computational complexity of K do not change the simple mathematical relationship of the heat exchange intensity Q being directly proportional to the outside wall area S and the inside and outside temperature difference Δt of the outside wall.
According to the embodiment, by changing the positioning method of the room fan coil, the traditional deep room setting mode of the room fan coil relative to the outer wall (taking the first room 5 as an example, the outer wall 502 in the first room 5 is a shallow room, the traditional room fan coil is arranged at a position far away from the outer wall 502 of the room, namely, the deep room), the novel structure relationship between the novel air conditioner and the building is innovated, the indoor temperature field distribution is changed, the temperature difference delta T between the inner and outer surfaces of the outer wall is reduced, and therefore the indoor and outdoor heat exchange strength Q and the building energy consumption are reduced.
The present embodiment takes hotel standard guest rooms as an example.
In the traditional air conditioner installation engineering, the room fan coil is arranged at the deep part of a room relative to an outer wall, the cooling operation under the standard working condition of an air conditioner in summer is taken as an example, the room fan coil arranged at the deep part of the room is sucked into the room return air at about 27 ℃ to cool and dehumidify, then cold air flow at about 14 ℃ after cooling and dehumidification passes through the upper space of the room and blows to the outer wall, the cold air flow is blocked and reflected by the outer wall, the cold air flow flows back to the lower part of the room fan coil from the middle lower space of the room and is sucked into the room fan coil again by the room fan coil to cool and dehumidify, and a new cycle is started.
If the ambient temperature is 32 ℃, the air outlet temperature of a traditional deeply arranged room fan coil is 14 ℃ when in refrigeration operation, the temperature of the vertically sinking airflow which is blown to the inner side of the outer wall is near 19 ℃, the return air is about 27 ℃, and the indoor-outdoor temperature difference at the outer wall is=32-19=13 ℃, then the outdoor environment leaks into the indoor heat quantity Q 1＝K×S×⊿T1 =13 K×S through the outer wall.
In the embodiment, the traditional deeply arranged room fan coil is innovatively arranged at a position close to the outer wall, so that a novel structural relation between the air conditioner and the building is created, the indoor temperature field is changed along with the change of the indoor temperature field and the outdoor temperature difference delta T of the outer wall, and accordingly the indoor and outdoor heat exchange strength Q and the building energy consumption are changed along with the change of the indoor and outdoor temperature difference delta T, as shown in fig. 16.
In this embodiment, the temperature of the air outlet of the room fan coil arranged close to the outer wall is 14 ℃ when the room is in cooling operation, the temperature of the vertical sinking airflow blown to the deep part of the room is near 19 ℃, the return air temperature at the outer wall is 25 ℃, the temperature of the air return opening 601 of the room fan coil is 27 ℃, the indoor and outdoor temperature difference at the outer wall is=32-25=7 ℃, then the outdoor environment leaks into the indoor heat Q 2＝K×S×⊿T2 =7kxs through the outer wall, and compared with the scene of the deep part of the room fan coil arranged in the traditional air-conditioning building structure, the heat of the environment leaking into the room is reduced (Q 1-Q2)/Q1 = (13-7)/13=46%).
The same architectural analysis and comparison is applicable to heating operation of the room fan coil in winter:
If the ambient temperature is 5 ℃, the air outlet temperature of a traditional deeply arranged room fan coil is 45 ℃ when the traditional room fan coil is in heating operation, the temperature of vertical sinking airflow blown to the inner side of an outer wall is near 35 ℃, the air return is about 21 ℃, and the indoor and outdoor temperature difference at the outer wall is 35-5=30 ℃, then indoor air leaks to the outdoor heat quantity Q 1＝K×S×⊿T1 =30KxS through the outer wall.
In the embodiment, in the room fan coil arranged close to the outer wall, the air outlet temperature during heating operation is 45 ℃ under the same environment temperature of 5 ℃ and the same room structure, the temperature of the vertical sinking airflow blown to the deep part of the room is also near 35 ℃, the return air temperature at the outer wall is 23 ℃, the return air temperature at the air outlet of the room fan coil is 21 ℃, the indoor and outdoor temperature difference at the outer wall is=23-5=18 ℃, then indoor air leaks to the outdoor environment through the outer wall to enable the heat quantity Q 2＝K×S×⊿T2 =18KxS, and compared with the scene arranged at the deep part of the room fan coil in the traditional air conditioner building structure, the heat quantity of the indoor leakage to the outdoor environment is reduced (Q 1-Q2)/Q1 = (30-18)/30=40%).
According to the embodiment, from building physics research analysis, a traditional setting mode of a room fan coil relative to an outer wall is innovatively set to the outer wall or a position close to the outer wall by changing a setting method of the room fan coil, novel structural relation between an air conditioner and a building is innovated, reverse phase change of a room air temperature field is promoted, indoor temperature field distribution is remodeled, a room summer 'inside-high-outside-low' temperature field is turned into a room 'outside-high-inside-low' temperature field, a room winter 'outside-high-inside-low' temperature field is turned into a room 'inside-high-outside-low' temperature field, and temperature difference T between the inside and outside of the outer wall is reduced, so that indoor and outdoor heat exchange strength Q and building energy consumption are reduced.

The present embodiment is further improved on the basis of any one of the above embodiments. In this embodiment, referring to fig. 1, the air exhaust module 2 includes a central air duct 24 and an air exhaust fan 22, the air return duct 3 of each room is connected to the central air duct 24, the central air duct 24 is connected to the air suction opening of the air exhaust fan 22 through at least one rear air duct 23, and the air outlet of the air exhaust fan 22 is communicated with the outside.
In this embodiment, the central air duct 24 is laid flat (not bent, not curled) over the group of rooms, the diameter of the central air duct 24 is not smaller than the diameter of the return air duct 6 of each room, and the diameter of the rear air duct 23 is not larger than the diameter of the central air duct 24.
In this embodiment, there is no limitation on where the central air duct 24 and the air exhaust fan 22 are specifically disposed in the room group in the building, for example, the central air duct 24 and the air exhaust fan 22 may be disposed in a kitchen, a balcony, a bathroom, a bedroom, a storage room, a living room, a passageway, etc., and the air exhaust fan 22 is disposed in the kitchen, and the central air duct 24 is disposed in the passageway, and since a cross beam is disposed between the kitchen and the passageway, the rear air duct 23 communicating the central air duct 24 and the air exhaust fan 22 passes through the cross beam, if only one rear air duct 23 is disposed between the air exhaust fan 22 and the central air duct 24, the diameter of the rear air duct 23 will be relatively thick, and the corresponding hole for the rear air duct 23 to pass through is relatively large on the cross beam, so as to damage the integrity and strength of the cross beam. Therefore, in this embodiment, the exhaust fan 22 and the central air duct 24 are preferably connected through two or more than two small rear end air ducts 23 with smaller diameters, and correspondingly, a plurality of small holes adapted to the small rear end air ducts 23 are formed on the cross beam, and the small rear end air ducts 23 respectively pass through the small holes.

If the exhaust fan 22 is arranged on a balcony, the balcony is communicated with the outside, so that an exhaust outlet of the exhaust fan 22 can be communicated with the outside without an exhaust pipe. If the exhaust fan 22 is provided in a room with an outer wall, an exhaust port of the exhaust fan 22 communicates with the outside through the exhaust duct 21.
The number of exhaust pipes 21 is not limited in this embodiment, and may be one or more. Since the exhaust fan 22 is provided in the building and the exhaust duct 21 is extended from the inside of the building to the outside of the building, the exhaust duct 21 is extended from the outside of the building. If the air outlet of the air exhaust fan 22 is communicated with the outside through only one air exhaust pipe 21, a total air outlet with a relatively large caliber for the air exhaust pipe 21 to pass through needs to be arranged on the outer wall of the building, and the integrity and the strength of the outer wall can be damaged. Therefore, in this embodiment, it is preferable that the exhaust pipes 21, that is, the exhaust fans 22, are provided with two or more total air outlets, and each total air outlet is provided with an exhaust pipe 21 communicating with the outside.
The air return pipes 6 of each room can be distributed at any position of the central air pipe 24, preferably, the rear end air pipe 23 is connected with the waist of the central air pipe 24, the air return pipes 6 of each room are distributed at two ends of the central air pipe 24, namely, two ends of the central air pipe 24 respectively reach pipe sections between the waist, namely, two sides of the waist of the central air pipe 24.
