Description

Technical Field

[0001] The invention relates to the technical field of ventilation in buildings, and in particular to a large-depth, non-recessed, energy-saving residential structure. Background Art

[0002] In traditional architectural design, the living room, bedroom, kitchen, bathroom, etc. of a house must be equipped with exterior walls and windows to achieve ventilation and lighting.

[0003] For example, the bathroom in a house, as an important private space for the physiological excretion and bathing of the residents, has received attention in residential design in recent years. Due to the low time utilization rate of the bathroom and the rigid demand for moisture and odor removal, the bathroom is usually placed on the north side of the house structure in residential structural design, occupying a section of the north side exterior wall to set up exterior wall windows for ventilation and air permeability to discharge moisture and odor from the bathroom.

[0004] In the design of residential buildings, engineers usually use floor plans that are repeated in an east-west direction to generate floor plans. Floor plans must implement the residential design specifications issued by the housing and construction departments and refer to the owner's habits. The living room, bedroom, kitchen, and bathroom are usually located on the south or north side so that they have exterior walls and windows to achieve ventilation and lighting. Such residential design specifications and habits have caused the north and south exterior walls to become scarce resources and are in great demand. If restrictions are placed on the length and area of the north and south exterior walls of the residence, it will be difficult to meet the demand for sufficient exterior walls and windows in the living room, bedroom, kitchen, and bathroom. If no restrictions are placed on the length and area of the north and south exterior walls of the residence to meet the demand for sufficient exterior walls and windows in the living room, bedroom, kitchen, and bathroom, a floor plan with a "large width and small depth" will be created. The residential building is like a playing card inserted in a community. The north-south thickness decreases, the structural strength of the building decreases, the surface area increases, and the building energy consumption increases.

[0005] Under the circumstances that the length and area of the north-south exterior walls of the house are restricted and the length and area of the north-south exterior walls are insufficiently distributed between the living room, bedroom, kitchen and bathroom, the residential designers have created the "recessed" structure of the residential building: the bathroom is set deep in the structure of the apartment, and a groove is wedged into the deep part of the house from the south or north side of the residential building. Through the groove, sunlight and air outside the building are introduced into the deep part of the house for lighting and ventilation of the bathroom. Please refer to Figure 1 and Figure 2 .

[0006] It needs to be emphasized that Figure 1 One of the recesses in the middle is usually responsible for ventilation, moisture removal and odor removal for four bathrooms of two households. There is usually a anti-viewing wall deep in the recess, which is set between the outer windows of the two opposite bathrooms to cut off the visual connection between the two opposite bathrooms to ensure the privacy of the bathrooms.

[0007] The concave structure of the residential building solves the problems of daylighting and ventilation in the deep bathrooms, expands the north-south depth of the residential building, and improves the building structure strength. However, the concave structure brings three problems:

[0008] ① It increases the complexity of the exterior wall construction and the exterior wall construction cost;

[0009] ② It increases the exterior wall area and building energy consumption;

[0010] ③ It reduces the building area and wastes valuable land resources. Summary of the Invention

Each residential module includes at least one functional space unit without exterior wall and exterior window.

The main supply air duct passes through this first room and communicates with the public space.

[0022] Preferably, the first room includes a room fresh air system, and the room fresh air system includes:

[0023] A room fresh air inlet is opened on the enclosure structure of the first room, and the room fresh air inlet communicates with the public space;

[0024] A room return air duct is connected to the main exhaust air duct; the return air inlet of the room return air duct is located inside the first room;

[0025] A fan coil unit is provided in the first room, which includes a housing, a fan is provided inside the housing, an air outlet and an air suction port are provided on the housing, and the distance between the room fresh air inlet and the air suction port is less than the distance between the room fresh air inlet and the return air inlet of the room return air duct.

[0026] Preferably, when the functional space unit is provided in the first room, the first room and the functional space unit share a return air duct, one end of this return air duct is located inside the functional space unit, and the other end is connected to the main exhaust air duct.

[0032] Preferably, the residential flat floor includes a number of residential units arranged in sequence along the horizontal direction, and each residential unit includes at least two residential modules.

[0033] Preferably, the residential flat floor is close to a square.

[0034] Compared with the prior art, the present invention has the following technical effects:

[0035] ① Improve the secondary environmental quality in the bathroom

[0036] The present invention replaces the traditional method of ventilation, dehumidification and odor removal of the external wall and external window of the bathroom with the fresh air technology of "no air supply duct, combination of air supply and exhaust, mainly exhaust, and two-way air flow throughout the house". The fresh air is pre-treated by filtering, cooling, dehumidifying (heating and warming) through the fresh air module. The temperature, humidity and cleanliness are higher than those of natural wind, fundamentally improving the secondary environmental quality in the bathroom and restoring the bathroom to a truly private space for family members without external walls and external windows.

[0037] ② Reduce the complexity of the residential exterior wall construction and the exterior wall construction cost

[0038] The building recess is a single-sided open groove structure wedged into the building, and usually the wedging depth reaches about half of the overall longitudinal thickness of the residential unit type; the three walls of the building recess are all exterior walls, and the technical requirements for wall insulation, anti-leakage and anti-cracking are high, and the construction is complex and the construction cost is high; since the present invention uses the ventilation of no air supply duct, combination of air supply and exhaust, mainly exhaust, and two-way air flow throughout the house to replace the external window ventilation of the bathroom, there is no building recess, greatly reducing the complexity of the residential exterior wall construction and the exterior wall construction cost.

[0039] ③ Reduce the exterior wall area and lower the building energy consumption

[0040] The specific surface area of a building is the external surface area of the building that is evenly distributed per unit building area in the building for receiving environmental thermal radiation and heat convection in summer and emitting thermal radiation to the environment for heat convection in winter. The lower the specific surface area, the weaker the energy exchange intensity between the internal space of the building and the environment; since the present invention has no concave structure, the exterior wall area is reduced by more than 1 / 3, the specific surface area is reduced by more than 1 / 3, and the building energy consumption is significantly reduced by more than 1 / 3.

[0041] Although the present invention also brings an increase in the energy consumption of lighting and ventilation in the "dark room" deep in the building; however, these two energy consumptions can be ignored compared with the energy consumption of air conditioning (heating): due to the rapid progress of semiconductor lighting (LED) technology that replaces traditional incandescent lamps and fluorescent lamps, the luminous efficiency of the light source has been improved to the extreme, and the lighting energy consumption in private spaces such as studies and bathrooms can be controlled within 1w / m 2Horizontal on the left and right, up to 10 higher than that in summer and winter per unit building area 2 w / m 2 The air conditioning (heating) energy consumption is two orders of magnitude lower; in the fresh air replacement condition, according to the fresh air replacement four times a day, each ventilation volume of 1000m 3 , the total wind pressure of each ventilation process is 100pa, and the total ventilation efficiency of the whole process is 0.6. The daily ventilation power consumption is only 0.2kwh.

[0042] Now, the building energy consumption (mainly air conditioning and heating energy consumption) accounts for up to 25% of the total social energy consumption; under the environmental policy of "carbon peak and carbon neutrality", the present invention has important technical and social significance.

[0043] ④ Increase the built-up area within the residential unit to make full use of precious land resources

[0044] Since the present invention does not have an indentation in the residential building, the space where the indentation in the traditional design is located is redesigned and classified as the living area within the unit, which can increase the building area by about 4%, including about 1% of the horizontal cross-sectional area of the external wall that has been included in the planned area, increase the built-up area within the residential unit, and make full use of precious land resources.

[0045] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. Description of the Drawings

[0060] An energy-saving residential structure with a large depth and no inner recess provided by the present invention starts from two principles of building physics, namely, "artificial secondary environment is superior to the original ecological environment" and "the specific surface area of a building determines the building energy consumption intensity". With the fresh air system technology of "no air supply duct, combined supply and exhaust, mainly exhaust, and two-way air flow throughout the house" in the residence as the core, mechanical ventilation technology is adopted to solve the problems of fresh air replacement, dehumidification and odor removal in functional space units such as bathrooms. The functional space units such as bathrooms are restored to the real private spaces of family members without exterior walls and exterior windows. The residential structure design of "no inner recess, large depth and small width" is implemented to achieve the technical goals of fundamentally improving the internal secondary environmental quality of functional space units such as bathrooms, reducing the complexity and cost of exterior wall construction of the residence, reducing the exterior wall area and building energy consumption, increasing the building area within the residence and making full use of precious land resources.

[0061] The first principle of building physics on which the present invention is based is that "artificial secondary environment is superior to the original ecological environment". In terms of specific individual living conditions of human beings, that "artificial secondary environment is superior to the original ecological environment" has been verified many times: multi-storey and high-rise concrete residential buildings are superior to primitive caves, tap water is superior to original river water and groundwater, and flush toilets are superior to latrines; especially after the emergence of energy technologies such as artificial fire and air conditioners, cooked food at high temperature is superior to eating raw meat and drinking blood, semiconductor lighting is superior to sunlight radiation, the air-conditioning wind after cooling and dehumidifying in summer is superior to the ambient hot wind, and floor heating in winter is superior to open fires in the wild. In building physics, a space is a livable residence as long as it can keep out wind and rain, provide clean fresh air, appropriate lighting, clean drinking water and sanitary hot water, stable power and network signals, and can smoothly discharge foul air, excrement and garbage. Adhering to the building physics principle of "artificial secondary environment is superior to the original ecological environment", the present invention adopts the two-way flow fresh air system technology to make the fresh air replacement and foul air discharge effects in functional space units such as bathrooms reach the extreme, so that the air temperature and humidity, oxygen content, cleanliness and other indicators in the secondary environment of the building including functional space units such as bathrooms are all superior to the original natural environment, creating a residential secondary climate condition and living condition that originate from the environment and are higher than the environment.

[0062] The second principle of building physics on which the present invention is based is that "the specific surface area of a building determines the building energy consumption intensity"; the "specific surface area of a building" described in the present invention is defined as "the ratio of the exterior surface area of a building to the above-ground building area of the building", and essentially it is the exterior surface area evenly distributed per unit building area, with the unit of m 2 / m 2, is a dimensionless physical quantity, that is, the surface area of the building per unit building area in the building that receives environmental heat radiation and convection in summer and emits heat radiation to the environment for convection in winter. It reflects the energy characteristics and structural characteristics of the building and determines the energy consumption intensity of the building: if the specific surface area of the building is large, the surface area per unit building area of the building is large, the building energy consumption is high, the external wall material consumption is large, and the construction process is complex; on the contrary, if the specific surface area of the building is small, the surface area per unit building area is small, the building energy consumption is low, the external wall material consumption is small, and the construction process is relatively simple. From the perspective of reducing building energy consumption, the lower this value, the better. The lower the specific surface area, the weaker the energy exchange intensity between the internal space of the building and the environment; and to have this value low, the building must be large; because the total surface area of the building is proportional to the square of the building's linear dimension, and the total building area is proportional to the cube of the linear dimension, so the specific surface area, which is the ratio of the total surface area of the building to the total building area, is inversely proportional to the linear dimension: if the building's linear dimension is large, the specific surface area is low; if the building's linear dimension is small, the specific surface area is high.

[0063] Under current technical conditions, the specific surface area of ordinary buildings is 1.0m 2 / m 2 When the building surface area is reduced to 10 -1 m 2 / m 2 Order of magnitude, that is, 1m 2 The internal building area is only apportioned to 0.1m 2 When the external surface is of this magnitude, the energy exchange intensity between the interior space of the building and the environment is weak, and the building will inevitably have the energy characteristic of "extremely low energy consumption".

[0064] Starting from the above two principles of architectural physics, "artificial secondary environment is better than original ecological environment" and "specific surface area of building determines energy consumption intensity of building", the present invention adopts the fresh air system technology of "air duct-free supply and exhaust combined with exhaust-based whole-house two-way airflow", and uses mechanical ventilation technology to replace artificial ventilation of external windows of functional space units such as bathrooms to solve the problems of fresh air replacement and dehumidification and deodorization in the space; after eliminating the dependence of functional space units such as bathrooms on external windows for ventilation, dehumidification and deodorization, the present invention establishes and implements the residential structural design principle of "no recess, large depth and small width", and builds functional space units such as bathrooms in the middle of the apartment structure, and modifies the building recess set in the traditional design for ventilation needs of functional space units such as bathrooms into an inner space, and merges the two outer walls of the traditional recess into an inner wall, thereby fully realizing the goal of improving the air quality of the secondary environment in the bathroom and restoring functional space units such as bathrooms to private spaces without external windows, reducing the cost of external wall construction, reducing the area of external walls to reduce energy consumption, and increasing the building area within the suite to make full use of land resources.

[0065] The present invention relates to a large-depth concave-free energy-saving residential structure, which uses the fluid mechanics technology of a two-way flow fresh air system to guide and support the structural design of a residential building; the fresh air system relied on by the present invention includes a whole-house fresh air system with the characteristics of "no supply air duct, combined supply and exhaust, and mainly exhaust, two-way air flow throughout the house".

[0066] In the present invention, a large-depth concave-free energy-saving residential structure includes a number of vertically arranged residential floors, and each residential floor includes a number of residential modules arranged in sequence along the horizontal direction, with no concavity between adjacent residential modules; each residential module includes at least one functional space unit without exterior walls and exterior windows. The present invention does not specifically limit the functional space unit, which can be a bathroom, a storage room, a music room, a tea room, a study room or a yoga room, etc. A fresh air inlet is provided on the enclosure structure of this functional space unit, and furthermore, a return air duct is provided in this functional space unit; each residential module includes a whole-house fresh air system, and the whole-house fresh air system can refer to the whole-house fresh air system in the patent application with the application number 202110597245.7 and the invention name of a fresh air system for a fresh air room and a whole-house fresh air system using secondary negative pressure to send fresh air submitted by the applicant to the State Intellectual Property Office on May 28, 2021.

[0069] A main exhaust air duct, which is communicated with the main exhaust air outlet, and the return air duct is connected to the main exhaust air duct;

[0070] When the whole-house fresh air system operates, fresh air enters the functional space unit through the fresh air inlet, and pushes the dirty air in the functional space unit into the return air duct, and is discharged to the outside through the main exhaust air duct.

[0071] In the present invention, the residential module further includes at least one first room and a common space communicating with the first room. The fresh air inlet of at least one of the functional space units communicates with the common space, that is, the functional space unit is located outside the first room and the common space; or / and, at least one of the first rooms is provided with the functional space unit, and the fresh air inlet of the functional space unit communicates with the common space through the first room. The present invention does not specifically limit the house type structure of the residential module, as long as it includes a functional space unit without external walls and external windows; moreover, the present invention does not limit the number of functional space units without external walls and external windows. The functional space unit can directly communicate with the common space through its fresh air inlet; it can also be set in a room, that is, the functional space unit communicates with the common space through this room; it can also include multiple functional space units, at least one functional space unit directly communicates with the common space through its fresh air inlet, and at least one functional space unit communicates with the common space through the room where it is located.

[0075] As a third embodiment, the first room has external walls and external windows. The total fresh air inlet is arranged on the outer wall of one of the first rooms. A total air supply duct is provided on the total fresh air inlet, and the total air supply duct passes through this first room and communicates with the common space.

[0076] The difference between the first room and the second room is that the first room is provided with a room return air duct, while the second room is not provided with a room return air duct.

[0077] The above-mentioned rooms can be storage rooms, music rooms, tea rooms, study rooms, bedrooms or yoga rooms, and the present invention does not limit this.

[0078] The common space can be a living room, a dining room, a corridor, etc.

For the room fresh air system, please refer to the room fresh air system in the patent application for invention with the application number 202110597245.7 and the invention title of "A Room Fresh Air System and a Whole-House Fresh Air System for Sending Fresh Air into a Room by Using Secondary Negative Pressure" submitted by the applicant to the State Intellectual Property Office on May 28, 2021. Specifically, the room fresh air system includes:

[0080] A room fresh air inlet, which is opened on the enclosure structure of the first room and is communicated with the public space. In the present invention, there is no specific limitation on where the room fresh air inlet is specifically arranged in the first room. For example, it can be arranged on the wall of the first room, or on the lintel of the door of the first room, or on the rotatable door leaf of the door of the first room. In this embodiment, if the room fresh air inlet is arranged on the wall of the first room, then the room fresh air inlet is preferably arranged on the inner wall of the first room. In order to reduce the opening of holes in the wall, in this embodiment, the room fresh air inlet can be arranged on the lintel of the door of the first room, that is, on the lintel above the door, or on the door leaf of the door of the first room. In order to simplify the structure and construction process, the door can not be provided with a lintel, and the door frame can be made higher, that is, the door leaf can also be made higher. Therefore, the room fresh air inlet can be arranged at the upper, middle or lower part of the door leaf, and can be specifically determined according to the setting positions of the return air inlet of the room return air duct and the air suction inlet of the fan coil unit; In the present invention, the room fresh air inlet can be provided with a damper or not, which can be set according to actual use requirements;

[0081] A room return air duct, which is communicated with the main exhaust air duct; the return air inlet of the room return air duct is located in the first room;

[0082] A fan coil unit is arranged in the first room. It includes a housing, a fan is arranged inside the housing, an air outlet and an air suction port are arranged on the housing, and the distance between the fresh air inlet of the room and the air suction port is less than the distance between the fresh air inlet of the room and the air return port of the room return air duct; a heat exchanger is also arranged inside the housing, and the heat exchanger is connected to a circulating unit that provides a heat exchange medium for it. In this embodiment, the fan coil unit is an indoor unit of a split air conditioner, and the indoor unit is connected to the outdoor unit of the split air conditioner to form a refrigerant circulation loop. Under the action of the fan, air enters the housing from the air suction port, passes through the heat exchanger and is discharged from the air outlet. This embodiment does not limit the specific type of the air conditioner. For example, it can be a central air conditioner, a split air conditioner, or a combination of a central air conditioner and a split air conditioner. For example, the fan coil unit can be a wall-mounted unit, a cabinet unit, a concealed fan coil unit or a surface-mounted fan coil unit, and the outdoor unit can be an outdoor unit of a central air conditioner water machine or an outdoor unit of a split air conditioner. Each indoor unit and each outdoor unit can be randomly combined. Specifically, as an embodiment, the fan coil unit is a fan coil unit at the end of a central air conditioner water machine or an indoor unit at the end of a central air conditioner fluorine machine installed on the ceiling in the room. The fan coil unit is a fan coil unit at the end of a central air conditioner water machine or an indoor unit at the end of a central air conditioner fluorine machine installed on the ceiling in the room. The fan coil unit is connected to the outdoor unit of the central air conditioner water machine to form a cold and hot water circulation loop, or is connected to the outdoor unit of the central air conditioner fluorine machine to form a refrigerant circulation loop. As a second embodiment, the fan coil unit is an indoor wall-mounted unit of a split air conditioner installed on the inner wall of the first room or an indoor fan coil unit of a split air conditioner installed on the ceiling in the room. The indoor wall-mounted unit or the indoor fan coil unit is connected to the outdoor unit of the central air conditioner or the split air conditioner to form a refrigerant circulation loop. In summary, no matter which type of air conditioner, it is applicable to the fan coil unit provided in this embodiment.

[0083] The functional space unit may also include the room fresh air system in the invention patent application with the application number 202110597245.7 and the invention name of a fresh air system for a room using secondary negative pressure to send fresh air and a whole-house fresh air system submitted by the applicant to the State Intellectual Property Office on May 28, 2021. Specifically, a fan coil unit is also arranged inside the functional space unit. The fan coil unit includes a housing, a fan is arranged inside the housing, an air outlet and an air suction port are arranged on the housing, and the distance between the fresh air inlet of the functional space unit and the air suction port is less than the distance between the fresh air inlet of the functional space unit and the air return port of the room return air duct. Of course, the fan coil unit may not be arranged inside the functional space unit, and it can be set according to specific usage requirements.

[0084] When the whole house fresh air replacement is in operation, the total fresh air module, room fan coil and total exhaust module are started. The fresh air positive pressure push of the total fresh air module and the dirty air negative pressure extraction of the total exhaust module work at the same time, forming a "two-way flow" whole house fresh air replacement, reflecting the ventilation technology characteristics of "no air supply pipe supply and exhaust combined with exhaust-dominated whole house two-way airflow"; the whole house fresh air replacement process is divided into three stages:

[0085] 1. Fresh air supply section

[0086] The whole-house fresh air module inhales fresh air from the environment and performs pre-treatment such as filtration, cooling and dehumidification (heating), and then delivers fresh air with temperature, humidity, cleanliness and oxygen content that meet the standards directly under slight positive pressure into the living room corridor, which is the public space in the suite, and directly to the doorheads of functional space units such as rooms and bathrooms.

[0087] 2. Fresh air replacement section

[0088] Under the negative pressure generated by the suction of the return air outlet of the return air duct of the functional space unit such as the bathroom, fresh air flows into the functional space unit such as the bathroom from the fresh air outlet set far away from the return air outlet, driving the moisture, odor and polluted air of the functional space unit such as the bathroom into the return air duct of the functional space unit such as the bathroom;

[0089] 3. Dirty air discharge section

[0090] The humid, smelly and polluted air entering the return air duct of the functional space unit such as the bathroom quickly flows into the main exhaust duct, enters the main exhaust module, is pressurized again by the exhaust fan, and finally discharged to the outdoor atmosphere for diffusion.

[0091] The present invention is based on the architectural physics principle of "artificial secondary environment is better than the original ecological environment", relying on the ventilation system of "air supply and exhaust without air supply duct combined with exhaust-dominated bidirectional airflow throughout the house", and using mechanical ventilation technology to replace artificial ventilation of external windows of functional space units such as bathrooms to solve the problems of fresh air replacement and dehumidification and deodorization in these spaces, improve the air quality of these spaces and restore the essence of private spaces without external windows of functional space units such as bathrooms, making "private deep bathrooms without recessed ventilation" a reality;

[0092] Based on the architectural physics principle of "the specific surface area of a building determines the building energy consumption intensity", this invention implements the residential structure design principle of "no concave, large depth, and small width". It places functional space units such as bathrooms in the middle of the household structure, redesigns the concave areas in the building that were originally set for ventilation of functional space units such as deep bathrooms as internal space within the unit, and combines the two outer walls of the traditional concave building into one inner wall. Since the functional space units such as bathrooms are placed inside, they no longer compete with other living rooms, bedrooms, and kitchens for the outer walls and windows of the residence. This enables effective control of the building width, suppresses the high-energy consumption design concept of "large width and small depth", expands the depth of the residential building, reduces the area and specific surface area of the residential exterior wall, reduces the total intensity of energy exchange between the inside and outside of the building, and thus significantly reduces the building energy consumption.

[0093] The advantages of this energy-saving residential structure with large depth and no concave of the present invention are as follows:

[0094] ① Improve the secondary environmental quality in the bathroom

[0095] This invention replaces the traditional method of ventilation, dehumidification, and odor removal through exterior walls and windows of the bathroom with the fresh air technology of "no air supply duct, combined supply and exhaust with exhaust as the main, and two-way air flow throughout the house". The fresh air is pre-treated by the fresh air module for filtration, cooling, dehumidification (heating and warming), with temperature, humidity, and cleanliness higher than natural air, fundamentally improving the secondary environmental quality in the bathroom and restoring the bathroom to a truly private space for family members without exterior walls and windows.

[0096] ② Reduce the complexity of residential exterior wall construction and the construction cost of exterior walls

[0097] The building concave is a single-sided open groove structure wedged into the building, usually with a wedging depth reaching about half of the overall longitudinal thickness of the residential unit. The three walls of the building concave are all exterior walls, with high technical requirements for wall insulation, leakage prevention, and crack prevention, and complex construction and high construction costs. Since this invention uses the combined supply and exhaust with exhaust as the main and two-way air flow throughout the house for ventilation instead of exterior window ventilation of the bathroom, there is no building concave, significantly reducing the complexity of residential exterior wall construction and the construction cost of exterior walls.

[0098] ③ Reduce the exterior wall area and lower the building energy consumption

[0099] The specific surface area of a building is the exterior surface area of the building that is evenly distributed per unit building area for receiving environmental heat radiation and heat convection in summer and emitting heat radiation to the environment for heat convection in winter. The lower the specific surface area, the weaker the energy exchange intensity between the internal space of the building and the environment. Due to the non-concave structure of this invention, the exterior wall area is reduced by more than 1 / 3, the specific surface area is reduced by more than 1 / 3, and the building energy consumption is significantly reduced by more than 1 / 3.

[0100] ④ Increase the built-up area within the residential unit and make full use of precious land resources

[0101] Since the present invention does not have a residential building recess, the space where the building recess in the traditional design is located is redesigned and included in the living area of the suite, which can increase the construction area by about 4%, including about 1% of the already calculated horizontal cross-sectional area of the exterior wall, thereby increasing the construction area of the residential suite and making full use of precious land resources.

[0102] The following will describe in detail a large-depth, non-recessed energy-saving residential structure provided by the present invention in conjunction with the accompanying drawings. The following embodiments are implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are given. However, the protection scope of the present invention is not limited to the following embodiments. Those skilled in the art can modify and polish the present invention without changing the spirit and content of the present invention.

[0103] Example 1

[0104] Please refer to Figures 3 to 5 This embodiment provides a large-depth, non-recessed, energy-saving residential structure, including a plurality of residential floors, wherein the residential floors include a plurality of residential modules 0 arranged in sequence in the horizontal direction, wherein there is no recess between two adjacent residential modules 0, and the two adjacent residential modules 0 are separated by a partition inner wall. The residential module 0 includes a public space 6, a functional space unit without exterior walls and windows and communicating with the public space 6, and at least one room 1, wherein both the public space 6 and the room 1 have exterior walls and windows, and a fresh air outlet 811 is provided on the enclosure structure of the functional space unit, and the functional space unit communicates with the public space 6 through the fresh air outlet 811. In addition, the functional space unit is also provided with a return air duct 9, and the return air outlet 91 of the return air duct 9 is located in the functional space unit. The room 1 includes a room fresh air system. For the room fresh air system, please refer to the application number 202110597245.7 submitted by the applicant to the State Intellectual Property Office on May 28, 2021, and the invention name is a room fresh air system in the invention patent application for a room fresh air system and a whole-house fresh air system using secondary negative pressure to deliver fresh air. Specifically, the room fresh air system includes:

[0105] A room fresh air vent 24 is provided on the door header of the room 1, and the room fresh air vent 24 is communicated with the public space 6;

[0106] A room return air duct 23, wherein a return air outlet 231 of the room return air duct 23 is located in the room 1;

[0107] The fan coil unit 22 is arranged in the room 1, and includes a shell, a fan is arranged in the shell, an air outlet 221 and an air intake 222 are arranged on the shell, and the distance between the room fresh air outlet 24 and the air intake 222 is smaller than the distance between the room fresh air outlet 24 and the return air outlet 231 of the room return air duct 23;

[0108] The residential module 0 includes a whole-house fresh air system. The whole-house fresh air system can refer to the whole-house fresh air system in the patent application for invention with the application number 202110597245.7 and the invention name of a fresh air system for a fresh air room and a whole-house fresh air system using secondary negative pressure to send fresh air submitted by the present applicant to the National Intellectual Property Administration on May 28, 2021. Specifically, the whole-house fresh air system includes:

[0109] A main air supply outlet is arranged on the outer wall of the public space 6, and a main fresh air module 4 is provided on the main air supply outlet;

[0110] A main air exhaust outlet is arranged on the outer wall of the residential module 0. In this embodiment, the setting position of the main air exhaust outlet is not specifically limited. For example, it can be arranged on the outer wall of a public space 6, or on the outer wall of a room 1, or on the outer wall of a kitchen, etc. As long as there is an outer wall, it can be set; a main air exhaust module 5 is provided on the main air exhaust outlet;

[0111] A main air exhaust duct 10 is communicated with the main air exhaust outlet, and the return air ducts 9 of the functional space units and the room return air duct 23 are all communicated with the main air exhaust duct 10;

[0112] During the whole-house fresh air replacement operation, the main fresh air module 4 and the main air exhaust module 5 are started. The positive pressure push of fresh air by the main fresh air module 4 and the negative pressure extraction of dirty air by the main air exhaust module 5 work simultaneously to jointly form a "two-way flow" whole-house fresh air replacement, reflecting the ventilation technical characteristics of "no air supply duct, combined supply and exhaust with exhaust as the main, and whole-house two-way air flow". Please refer to Figure 3 .

[0113] The functional space unit can be a structure without outer walls and outer windows such as a bathroom, a storage room, a music room, a tea room, a study room or a yoga room, etc. In this embodiment, the functional space unit is taken as the bathroom 8 as an example for detailed description. A fresh air inlet 811 is provided at the lower part of the door leaf of the bathroom door 81. The air return inlet 91 of the return air duct 9 of the bathroom 8 is arranged far away from the fresh air inlet 811 of the bathroom 8, aiming to prevent fresh air short circuit;

[0114] The whole process of fresh air replacement in the bathroom is also divided into three small stages, which are composed of "fresh air entering the bathroom", "fresh air replacement in the bathroom" and "dirty air exhausting from the bathroom". Please refer to Figure 4 and Figure 5 , specifically as follows:

[0115] 1. Fresh air supply stage in the bathroom

[0116] The whole-house total fresh air module 4 inhales the ambient fresh air and performs pre-treatment such as filtration, cooling and dehumidification (heating), and then directly delivers the fresh air with the temperature, humidity, cleanliness and oxygen content meeting the standards into the living room corridor of the public space 6 of the residential module at a slight positive pressure, directly reaching each room 1 and the bathroom 8;

[0117] 2. Bathroom fresh air replacement section

[0118] Under the negative pressure generated by the suction of the return air outlet 91 of the bathroom return air duct 9, fresh air flows into the bathroom 8 from the fresh air outlet 811 arranged far away from the return air outlet 91, driving the humid, smelly and polluted air of the bathroom 8 into the bathroom return air duct 9;

[0119] 3. Toilet dirty air discharge section

[0120] The humid, smelly and polluted air entering the bathroom return air duct 9 quickly flows into the main exhaust duct 10, enters the exhaust module, is pressurized again by the exhaust fan, and finally is discharged to the outdoor atmosphere for diffusion.

[0121] This embodiment starts from the concept of "artificial secondary environment is better than the original ecological environment", relying on the "ductless supply and exhaust combined with exhaust-dominated two-way airflow throughout the house" ventilation system, and uses mechanical forced ventilation technology instead of artificial ventilation through the bathroom exterior window to solve the problems of fresh air replacement and dehumidification and deodorization in the bathroom, improve the air quality in the bathroom and restore the essence of the private space without external windows in the bathroom, making the "private deep bathroom without recessed ventilation" a reality.

[0122] This embodiment starts from the concept of "building specific surface area determines building energy consumption intensity", implements the residential structure design principle of "no recess, large depth and small width", builds the bathroom into the middle of the apartment structure, redesigns the building recess area set up for ventilation needs of deep bathrooms in traditional design into a suite space, and merges the two exterior walls of the traditional building recess into one interior wall; in this embodiment, since the bathroom is built-in, the bathroom no longer competes with the living room, bedroom and kitchen for the exterior walls and windows of the house, the width of the house is effectively suppressed and compressed, the depth of the residential building is expanded, the exterior wall area and specific surface area of the house are reduced, the total intensity of energy exchange between the inside and outside of the building is reduced, and the building energy consumption is reduced.

[0123] Example 2

[0124] The difference between this embodiment and embodiment 1 is that the toilet 8 in embodiment 1 is arranged outside the room 1, while the toilet 8' in this embodiment is arranged inside the room 1. Figures 6 to 10, the bathroom 8' is set inside the master bedroom, that is, fresh air can only be supplemented from the master bedroom to implement fresh air replacement in the bathroom. In this embodiment, a fresh air inlet 811 is provided at the lower part of the door leaf of the bathroom door 81. The room return air duct 23 of the room 1, i.e., the master bedroom, shares the return air duct 9 of the bathroom 8'. That is, it is equivalent to omitting the room return air duct 23 and only the return air duct 9 of the functional space unit needs to be retained. And one end of this return air duct 9 is located inside the bathroom 8', and the other end is connected to the main exhaust air duct 10. In this embodiment, the return air inlet 91 of the return air duct 9 of the bathroom 8' is arranged far away from the fresh air inlet 811 of the bathroom 8' to prevent fresh air short-circuiting, ensure that fresh air can completely replace the dirty air in the bathroom, and improve the fresh air replacement efficiency of the bathroom.

[0125] In this embodiment, the fresh air flow in the residential module 0 is from the main fresh air module 4 → the living room aisle → the room fresh air inlet 24 of the master bedroom → the master bedroom fan coil unit 22 to implement "the fan coil unit 22 sucks deeply under negative pressure for a second time and replaces and clears the air above the master bedroom" → the fresh air inlet 811 at the lower part of the door leaf of the master bathroom 8' → fresh air replacement in the bathroom 8' → the ceiling return air inlet 91 of the bathroom 8' → the bathroom return air duct 9 → the main exhaust air module 5 → discharged into the environment, and the fresh air replacement air flow route is very long.

[0126] In this embodiment, a large-depth non-recessed energy-saving residential structure adopts the technology of the whole-house two-way flow fresh air system in the residence, and uses the fluid mechanics technology of the two-way flow fresh air system to support the structural design of the residential building; the fresh air system relied on in this embodiment includes a whole-house fresh air system with the characteristics of "no supply air duct, combined supply and exhaust, mainly exhaust, and two-way air flow throughout the house" and / or a room fresh air system using the room air-conditioning door head fan coil unit 22 with the characteristics of "the door head fan coil unit 22 sucks deeply under negative pressure for a second time and replaces and clears the air above the room".

[0127] The inner walls, outer walls and doors and windows of the existing buildings divide the originally spacious and open residential building space into several space units such as the living room, bedroom, study, kitchen, bathroom, storage room, etc. These space units are not only difficult to achieve natural ventilation with the environment, but even forced ventilation is very difficult to operate. Because there are many resistance problems in residential ventilation: the multiple inner and outer walls of the outer wall and inner wall generate blocking resistance to the air flow, there are also ventilation blind areas behind multiple obstacles in the rooms within the residential unit, and there are also fresh air filtration, heat exchange, etc. to achieve the appropriate indoor temperature, humidity and cleanliness goals. All these resistance factors make it necessary to apply multiple fan pressurizations to the air flow throughout the process of residential ventilation to promote the air flow transportation.

[0128] The difficulty in residential ventilation lies in room ventilation. Because, even if the total fresh air module 4 and the total exhaust module 5 for the whole house are set up, and the conditions are met to send fresh air through the living room corridor to the fresh air inlets 24 of each room and extract the polluted air from each room through the room return air ducts 23 and the total exhaust duct 10 to the outdoors, it is still impossible to achieve high-efficiency fresh air replacement in the room if the fresh air inlets 24 do not have the power to relay the air supply, but only rely on the positive pressure of the air supply in the living room corridor and the negative pressure of the room return air duct 23: First, there are a large number of air leakage channels in the living room corridor to the external environment of the house, resulting in the fresh air sent from the living room corridor to the door heads of each room being only a "micro positive pressure" of 1 Pa level and impossible to be a "positive pressure" of 10 1 Pa, 10 2 Pa level. Driven by this "micro positive pressure", it is difficult for the fresh air in the living room corridor to generate a speed of more than 3 m / s and the corresponding dynamic pressure head when passing through the fresh air inlets 24 of the rooms, and it is difficult to "stir" the internal air flow field of the rooms with great force; Second, the room negative pressure generated by the total exhaust module 5, the total exhaust duct 10 and the room return air duct 23 is not enough to pull the fresh air at the fresh air inlets 24 of the rooms to generate a speed of more than 3 m / s and the corresponding dynamic pressure head. Especially when the return air inlets 231 of the room return air ducts 23 are set close to and on the same side as the fresh air inlets 24 of the rooms, serious fresh air short-circuit will occur, that is, the fresh air flow entering from the fresh air inlets 24 of the rooms does not obtain a high dynamic pressure head to make it rush into the main space of the room, but directly goes straight to the opening of the room return air duct 23 along the path with the shortest distance and the least resistance between the fresh air inlets 24 of the rooms and the return air inlets 231 of the room return air ducts 23, greatly reducing the fresh air replacement effect in the rooms and wasting fresh air resources.

[0129] The residential ventilation system relied on by a large-depth and non-recessed energy-saving residential structure in this embodiment includes a combined air supply and exhaust without an air supply duct and mainly exhausting with a two-way air flow throughout the house (for the whole house module 0) and a secondary negative pressure deep suction and high-level discharge in the room by the fan coil unit 22 (for the rooms within the suite).

[0130] The fresh air system of the whole house module 0 has the characteristic of "combined air supply and exhaust without an air supply duct and mainly exhausting with a two-way air flow throughout the house", including: a total air inlet set on the outer wall of public spaces 6 such as the living room to connect the public space 6 with the outside air, and a total fresh air module 4 is provided on the total air inlet; a total exhaust outlet communicating with the outside air on the outer wall, and a total exhaust module 5 is provided on the total exhaust outlet; a total exhaust duct 10 communicating with the total exhaust outlet, and is respectively connected to each room 1 through a number of room return air ducts 23.

[0131] When the whole-house fresh air replacement system is in operation, the main fresh air module 4, the fan coil unit 22 in the room, and the main exhaust module 5 are started. The fresh air is positively pushed by the main fresh air module 4, the relay transportation is carried out by the fan coil unit 22 in the room, and the dirty air is negatively exhausted by the exhaust module, working together to form a "two-way flow" whole-house fresh air replacement; The fresh air replacement in the bathroom of the room is divided into three sections throughout the process:

[0132] 1. Fresh air supply section

[0133] After the main fresh air module 4 inhales the ambient fresh air and performs pre-treatments such as filtration, cooling and dehumidification (heating and warming), the fresh air with qualified temperature, humidity and cleanliness is directly positively sent into the living room aisle of the residential module as a public space, reaching each room directly;

[0134] 2. Fresh air replacement section

[0135] Based on the primary negative pressure generated by the suction at the air return opening 91 of the bathroom air return duct 9 in the room, under the secondary negative pressure generated by the suction at the suction opening 222 of the fan coil unit 22 which is set close to the room fresh air opening 24, the suction opening 222 of the ceiling fan coil unit 22 is in the lowest pressure area in the room, forming a large pressure difference between the room fresh air opening 24 and the suction opening 222 of the fan coil unit 22. The fresh air quickly rushes into the room through the room fresh air opening 24 and is inhaled by the fan coil unit 22, then pressurized and accelerated and shot towards the opposite wall of the room. After being reflected by the opposite wall, it flows back to the side of the room door and the bathroom door, pressing the room air into the bathroom 8'; Under the action of the negative pressure generated by the suction at the air return opening 91 of the bathroom air return duct 9, the fresh air in the room rushes into the bathroom 8' from the bathroom fresh air opening 811 which is far from the bathroom air return opening 91, driving the wet, smelly and dirty air in the bathroom 8' into the bathroom air return duct 9;

[0136] 3. Dirty air discharge section

[0137] The dirty air entering the bathroom air return duct 9 quickly flows into the main exhaust duct 10, enters the exhaust module and is pressurized again by the exhaust fan, and finally is discharged to the outdoor atmosphere for diffusion.

[0138] The key link of the whole-house fresh air replacement is the fresh air replacement in the master bedroom and the bathroom.

[0139] The fresh air system for rooms inside a residential module has the characteristic of fresh air replacement in rooms, namely, "the header fan coil 22 creates a secondary negative pressure to deeply suck in and expel the air in the room from a higher position for replacement". During operation, the damper of the fresh air inlet 24 in the room opens, the fresh air inlet 811 in the bathroom exhausts the polluted air in the room, and the room fan coil 22 operates. The fresh air inlet 811 in the bathroom creates a primary negative pressure in the room. On the basis of this primary negative pressure, the operation of the fan coil 22 generates a secondary negative pressure at the air suction port 222 of the fan coil 22, making the air suction port 222 of the fan coil 22 in the lowest pressure area of the room. A large pressure difference is formed between the fresh air inlet 24 and the air suction port 222 of the fan coil 22 which are arranged closely, pulling the fresh air to quickly rush into the room and be sucked in by the air suction port 222 of the fan coil 22 for pressure increase, and then being ejected at high speed from the air outlet 221 of the fan coil 22. The ejected fresh air flow is reflected by the wall opposite to the fan coil 22 and then flows back to the side where the fan coil 22 is located, driving the room air to enter the fresh air inlet 811 in the bathroom which is set far from the fresh air inlet 24 in the room; under the action of the negative pressure generated by the suction at the air return port 91 of the bathroom return air duct 9, the fresh air rushes into the bathroom 8' from the fresh air inlet 811 which is set far from the air return port, driving the humid and stinky polluted air in the bathroom to enter the bathroom return air duct 9, as Figure 6 , Figure 7 , Figure 8 shown.

[0140] Starting from the concept of "artificial secondary environment is superior to the original ecological environment", this embodiment relies on the ventilation system of "no air supply duct, combined supply and exhaust with exhaust as the main, and two-way air flow throughout the house", and uses mechanical forced ventilation technology to replace the artificial ventilation of the external window of the bathroom to solve the problems of fresh air replacement, dehumidification and odor removal in the bathroom, improve the air quality of the bathroom and restore the essence of the private space of the bathroom without external windows, making it possible to have a "private deep bathroom without recessed ventilation".

[0141] Starting from the concept of "the specific surface area of a building determines the building energy consumption intensity", this embodiment implements the residential structure design principle of "no recess in the building and controlling the building facade width". The bathroom is placed in the middle of the household structure. The recessed area in the building that was originally set for the ventilation of the deep bathroom in the traditional design is redesigned into the space within the unit, and the two outer walls of the traditional building recess are combined and designed into one inner wall; since the bathroom is placed inside in this embodiment, the bathroom no longer competes with the living room, bedroom and kitchen for the external wall and external window of the residence, enabling the effective implementation of the control of the building facade width, and correcting the high-energy consumption design concept of "large facade width and small depth"; since the bathroom is placed inside in this embodiment, the facade width of the residence is effectively suppressed and compressed, and the depth of the residential building is expanded, as Figure 9 and Figure 10 shown. The area and specific surface area of the residential external wall are reduced, the total intensity of energy exchange between the inside and outside of the building is reduced, and the building energy consumption drops accordingly.

[0142] Embodiment 3

[0143] This embodiment is a further improvement based on the combination of Embodiment 1 and Embodiment 2. The residential module 0 provided in this embodiment is a three-section ultra-low energy consumption house type structure with a large depth and no concave. The vertical transportation systems such as elevators and stairs are arranged at the ends of the house type structure. This embodiment takes independent families as the object and adopts a spatial layout of a large depth and three sections. Single-function spaces such as bathrooms, storage rooms, music rooms, tea rooms, study rooms, yoga rooms, and some bedrooms are arranged in the middle of the three-section house type structure using a "dark room structure" without exterior walls and exterior windows, returning to the original meaning of private space. Public spaces such as living rooms and dining rooms 6 and some bedrooms are arranged at the north and south ends of the three-section house type structure using a "bright room structure" with exterior walls and exterior windows. The bright rooms at the north and south ends of the three-section house type structure and the dark rooms in the middle are connected in series by a corridor to assemble into a building structure unit with a "small frontage and large depth" chain structure, as Figure 11 shown.

[0144] A three-section ultra-low energy consumption house type structure with a large depth and no concave in this embodiment is supported by a two-way flow household fresh air air-conditioning system without a supply air duct. The household central air-conditioning system and the two-way flow fresh air system without a supply air duct can operate independently or synchronously, and are controlled by the same set of control systems.

[0145] This embodiment implements the ventilation principle of "combining supply and exhaust without a supply air duct, mainly exhausting, two-way air flow throughout the house, and the head fan coil creating a secondary negative pressure to deeply extract and replace the air in the room at a high position to clean the air". When the ventilation is running, the living room corridor is used instead of the supply air duct to deliver fresh air to the door heads of each room, and then the secondary negative pressure of the head fan coil 22 of the household central air-conditioning (or split air-conditioning) set near the fresh air inlet 24 of the door head room is used to suck the fresh air into the room and shoot it at a high speed towards the opposite wall window and reflect back, driving the dirty air in the room to flow into the room negative pressure return air outlet, effectively preventing the short circuit of fresh air from the fresh air inlet to the return air outlet in the room and improving the fresh air replacement efficiency in the room; Fresh air from the total fresh air module 4 on the balcony → living room corridor → door heads of each room → secondary negative pressure of the room fan coil 22 set near the fresh air inlet of the door head → the room drives the dirty air from the room → the room return air outlet set far from the fresh air inlet 24 of the room → the room return air duct 23 → the total exhaust air duct 10 → the total exhaust air module 5 is discharged outdoors, forming a complete two-way flow chain for fresh air supply and dirty air discharge.

[0146] When the fresh air system of a three-section ultra-low energy consumption house type structure with a large depth and no concave in this embodiment is running, the whole-house fresh air module, the room fan coil 22 set near the fresh air inlets of the door heads of each room in the whole house, and the whole-house exhaust air module are started. The positive pressure push of the fresh air from the whole-house fresh air module, the secondary negative pressure relay transportation of each room fan coil 22, and the negative pressure extraction of the dirty air by the whole-house exhaust air module work simultaneously to jointly form a "two-way flow" whole-house fresh air replacement, as Figure 12 shown.

[0147] In this embodiment, a three-section ultra-low energy consumption housing structure without internal concavity and with large depth is used as a building structure unit. The long side direction of the building structure unit is usually north-south, and the short side direction is east-west. Along the short side direction of the building structure unit, the building structure units are assembled side by side and repeatedly to assemble a building flat floor close to a square, as shown in Figure 13 Shown; then, taking the nearly square residential flat floor as a new basic module, it is assembled vertically to assemble a residential structure with extremely low specific surface area and structural energy-saving characteristics.

[0148] A three-section ultra-low energy consumption housing structure without internal concavity in this embodiment, due to the integration of the above ventilation and structure technologies, has the following advantages and positive effects compared with the prior art:

[0149] 1. Fundamentally improve the fresh air replacement efficiency of the building and the quality of the indoor secondary environment

[0150] First of all, the secondary pollution of the building air supply duct is eliminated. In this embodiment, public spaces such as the living room aisle and rooms that need to replace fresh air are used as air ducts, and all the fresh air supply ducts of the traditional building fresh air system are removed, eliminating the secondary pollution problems caused by condensation, dark and humid conditions inside the air supply pipeline, and serving as a culture medium for bedbugs, bacteria, viruses and microorganisms.

[0151] Secondly, the fresh air short circuit is prevented. In this embodiment, a room fresh air system is adopted in which the fresh air inlet 24 of the room is set close to the suction inlet 222 of the fan coil unit 22 and far from the return air inlet 231 of the room return air duct 23. Under the "secondary negative pressure" suction of the room return air duct 23 and the suction of the suction inlet 222 of the head-mounted fan coil unit 22 set nearby, the fresh air at the door head quickly flows into the room and is inhaled by the fan coil unit 22 and boosted and shot towards the outer wall. After being reflected by the outer wall, it flows back to the inner wall side where the door is located, driving the dirty air in the room into the room return air duct 23; fundamentally changing the fresh air short circuit problem in the traditional building fresh air system where fresh air cannot sink deeply but finds the shortest path and the least resistance from the fresh air inlet to the negative pressure exhaust outlet, and improving the fresh air replacement efficiency.

[0152] Thirdly, the indicators of the secondary climate conditions inside the building are better than those of the natural environment. A three-section ultra-low energy consumption housing structure without internal concavity in this embodiment, the environmental air is filtered and cooled and dehumidified (heated and warmed) by the fresh air module. The temperature, humidity, oxygen content, cleanliness and other indicators of the air entering the internal secondary climate environment of the building are all better than those of the original natural environment; in the rooms in the middle section of the three sections, the multiple walls completely block the environmental noise, and the indoor sound insulation effect reaches the extreme, making it easy to enter a state of undisturbed learning and cultivation; whether it is the indoor air quality or the sound and light environment, it has reached a new height of "originating from nature and being higher than nature".

[0153] 2. Reduce the cost of the fresh air system and the building cost

[0154] The present embodiment is a three-stage ultra-low energy consumption apartment structure with no inner recess and large depth. The public space in the whole house and the room that needs to replace the fresh air are used as the air duct. All the fresh air supply pipes of the traditional fresh air system are cancelled, and there is no need to set the room fresh air connection pipe that passes through the corridor ceiling and beams. It only needs "the room fresh air outlet 24 is set close to the air intake outlet of the wind disk and far from the return air outlet", which greatly reduces the material usage, on-site installation workload, and installation precision requirements of the whole house fresh air system, thereby greatly reducing the decoration cost;

[0155] This embodiment uses a three-section whole house space as a building structure unit, expands left and right along the short side of the building structure unit, repeatedly splices the building structure units, assembles a nearly square building floor, and then uses the nearly square floor as a new basic module to assemble vertically to assemble a building. This type of building has an extremely low specific surface area and structural energy-saving characteristics while greatly reducing the area of exterior walls and windows, thereby greatly reducing construction costs.

[0156] 3. Improved building safety level

[0157] The present embodiment is a three-stage ultra-low energy consumption apartment structure with no inner recess and large depth. Fresh air is distributed to each room through public spaces such as the living room and corridor. At the same time, the return air duct is used to extract the dirty air in each room under negative pressure and merge it into the main exhaust duct for centralized and unified exhaust. The building has ultra-high fire safety: when the smoke monitoring device of the building detects a fire in a room, the controller issues an instruction to close the negative pressure air intake ports of other exhaust branches except the exhaust branch connected to the return air duct 23 of the fire room, so that the exhaust fan can concentrate its capacity to extract the smoke in the fire room at a lower negative pressure, effectively preventing the smoke in the fire room from spreading to other areas and rooms, thereby effectively suppressing the development of the fire and buying precious time for rescue. In addition, due to the use of a micro-positive pressure air supply system in the public space of the living room and corridor, the people in the building only need to enter the space near the positive pressure air supply port to wait for rescue. The smoke cannot penetrate into the positive pressure space, and there is no need to cover the mouth and nose with a wet towel, and there is no need to tie a rope to escape down the building. It has ultra-high fire safety.

[0158] This embodiment adopts the room fresh air system technology in which the fresh air inlet is close to the air disk suction port and far from the return air inlet, and the ductless two-way flow whole-house fresh air system technology to assemble a three-section building structure unit with "small width and large depth", and then assembles a building floor from the three-section building structure units, and then uses the assembled building floor as a new basic module for vertical assembly to assemble a thick building, which has extremely excellent mechanical strength and seismic strength and has super high structural safety.

[0159] 4. Achieve structural building energy conservation

[0160] The specific surface area of ordinary buildings is 1.0m 2 / m2 Magnitude. In this embodiment, a three-section ultra-low energy consumption housing structure with no concave and large depth is adopted. The building structure with a small facade width and a large depth reduces the specific surface area index to an extremely low level, which can be reduced to less than 0.2 m 2 / m 2 or less. The energy exchange intensity per unit building area with the external environment is greatly weakened, and it has excellent structural energy-saving characteristics. The cooling load of air conditioners in summer and the heating load of air conditioners in winter are reduced by more than 1 / 2 compared with ordinary buildings, far beyond the building energy-saving effects brought by technical innovations such as reducing the thermal conductivity of building wall materials and window materials;

[0161] Although, the building structure of a three-section ultra-low energy consumption housing structure combination in this embodiment also brings an increase in the energy consumption of lighting and ventilation in the deep "dark rooms" of the building; however, these two energy consumptions can be ignored compared with the air-conditioning (heating) energy consumption: due to the rapid progress of semiconductor lighting (LED) technology that replaces traditional incandescent lamps and fluorescent lamps, the luminous efficiency of electric light sources has been improved to the extreme, and the lighting energy consumption of private spaces such as study rooms and bathrooms can be controlled at about 1 W / m 2 or so, which is 2 orders of magnitude lower than the air-conditioning (heating) energy consumption of up to 10 2 W / m 2 per unit building area in summer and winter; and in the fresh air replacement condition, according to four fresh air replacements per day, each ventilation volume of 1000 m 3 , the total wind pressure of 100 pa for each ventilation process, and the total ventilation efficiency of 0.6 for the whole process, the daily ventilation power consumption is only 0.2 kwh.

[0162] Currently, the building energy consumption (mainly air-conditioning and heating energy consumption) accounts for as high as 25% of the total social energy consumption; under the environmental policy of "carbon peak and carbon neutrality", this embodiment has important technical and social significance.
