Description

Adopt not having blast pipe bidirectional flow local new trend system building
Technical Field
The invention relates to the technical field of ventilation in buildings, in particular to a building adopting a blast-pipe-free bidirectional flow local fresh air system.
Background
Under the existing building design specifications, the building structural design needs to meet the rigid constraint of natural ventilation lighting indexes.
In order to enable the building to meet the constraint requirement of natural lighting and ventilation, designers must adopt technical measures of multiple discrete buildings, single building thickness reduction, lighting and ventilation structural joints arranged in each building and the like, so that the large-area wide and small-depth building is permeable in north and south, windows in kitchens and toilets are outward, and sufficient natural lighting and ventilation are ensured.
The specific surface area of the building is the ratio of the total external surface area of the building to the total building area, and reflects the energy characteristics and the structural characteristics of the building. The technical measures of reducing the thickness of a single building, arranging a special lighting and ventilating structural joint for each building and the like are adopted, so that the area of the outer vertical surface of each building is large, the effective building area is small, and finally the specific surface area of the building is large on the index of the specific surface area, the internal and external energy exchange strength of the building is high, and the energy consumption of the building is high.
The energy consumption of the residential building is high, and is related to the performance of wall heat-insulating materials and the performance of residential energy equipment such as air conditioners, but the specific surface area of the residential building is also a hedging factor, and the specific surface area of the residential building is small, so that the surface area of an outer wall shared by the unit building area of a residential space is small, and the energy consumption of the building is low; on the contrary, the specific surface area of the residential building is large, the unit building area of the residential space is large in the external wall surface area, and the building energy consumption is high.
At present, the specific surface area index of the residential building is restricted by the traditional planning specification and the building design specification, and the innovative development of the residential building is restricted. The large-span innovation of the residential building technology and the matching technology is promoted, the constraint of the traditional planning specification and the building design specification is broken through, the specific surface area of the building is greatly reduced, and the large-span innovation is an important technical direction for solving the problem of high energy consumption of the residence.
The specific surface area of the building is reduced, only one road with the face width reduced and the depth increased is used for reducing the face width of the building unit, and the key for determining whether the technical road with the face width reduced and the depth increased is on or off is the ventilation lighting fire-fighting problem, particularly the ventilation problem, in the building.
If the ventilation problem of the deep part of a building with small width and large depth, namely the problems of fresh air entering and dirty air exhausting, can be solved, the aims of increasing the three-dimensional size of the building, reducing the specific surface area and reducing the energy consumption of the building can be achieved.
In a building, particularly a house, because different household functional spaces such as a living room, a bedroom, a study, a kitchen, a toilet, a storeroom and the like need to be arranged, a large-scale building space with good ventilation and lighting conditions is divided into a plurality of unit spaces with smaller sizes by internal walls and doors and windows; the walls and the doors and the windows cut off the air flow and light communication among all the unit spaces, and the ventilation and lighting conditions of all the unit spaces are poor; meanwhile, in buildings, especially houses, indoor air is polluted due to the breathing and excretion of people and animals, the diffusion of fuel gas and oil smoke in the cooking process, the drifting of water vapor in the bathing and cleaning process, the volatilization of benzene aldehyde components in various artificial materials and the like; because of the obstruction of the inner wall bodies and the doors of the buildings, the indoor dirty air cannot be diffused, diluted and discharged, and the serious problem of the air quality inside the buildings is caused.
In recent years, some real estate enterprises and owners have tried to achieve a great effect by arranging a bidirectional flow fan duct, as shown in fig. 1, by forcibly introducing fresh outdoor air into a room and guiding dirty indoor air to the outside, where hollow arrows and solid arrows represent bidirectional flows, i.e., fresh air introduced into the house and dirty air discharged from the house.
However, the bidirectional flow whole house fresh air system using the air supply duct and the air exhaust duct in large scale in the buildings, especially in the houses, has three problems:
1. secondary pollution of blast pipe
In the ventilation operation process and the shutdown stage of a fresh air system of a traditional bidirectional flow building, a large amount of dust which cannot be removed is accumulated in an air pipe and in decorative interlayers of the air pipe and a coating air pipe, bacteria and mold are bred, and a hotbed is provided for breeding and breeding mosquitoes, flies, bugs, cockroaches, even mice and the like; in particular, the inner wall of the pipeline of the blast pipe (fresh air pipe) is easy to be condensed, and the attached wet dust becomes a bacterial microorganism culture medium to generate new secondary pollution; bacteria, microorganisms, bedbugs, cockroaches, excrement and the like accumulated in the air supply pipe are blown into the indoor space along with fresh air during fresh air replacement, so that a new serious living room health and sanitation problem is brought.
In the outbreak period of Wuhan outbreak of coronavirus pneumonia in 2020, public health professionals emphasize domestic ventilation when prompting people to 'wash hands frequently, ventilate more, eat cooked food frequently and prick less' but emphasize that air conditioners are not switched on, especially household central air conditioners and fresh air systems without air pipes.
2. Poor fresh air replacement effect
Fresh air intake and dirty air outlet of new trend system all set up on the furred ceiling under the room ceiling in the room, though paid attention to in the design construction and drawn back the distance dislocation installation on the furred ceiling horizontal direction, but vertical direction is fresh air intake and dirty air outlet but can't stagger on the direction of height.
Because the new trend speed of minute air inlet mend is little, and the decurrent dynamic pressure head is very little, and the route of minimum resistance shortest distance between new trend air intake and the dirty air discharge port is sought to some new trend air current, and the discharge port is run straight along the furred ceiling face and goes, does not take part in room new trend replacement by deep sink, causes some new trend air current short circuit, has wasted the new trend resource, has produced the ventilation blind area in big region again simultaneously bottom the room and four corners, and the new trend replacement effect is poor.
3. The air supply and exhaust pipeline is complex and has high decoration cost
The fresh air system of the bidirectional flow building is provided with two sets of air inlet and exhaust main pipelines and end pipelines for entering and exiting each room, a channel-shaped whole-room pipeline system is constructed, fresh air is sent to each room by positive pressure, and dirty air in each room is sucked and exhausted by negative pressure.
These circuitous tortuous air supply tuber pipe and air exhaust tuber pipe, including main line and each room tip pipeline, not only the installation is complicated, still need to carry out the cladding decoration to the tuber pipe after the installation in order to improve visual effect, still need still in the indoor furred ceiling in order to cover fresh air and return air tuber pipe and business turn over wind gap, and the big construction process of material consumption is complicated, causes the new trend system to become the highest subentry among the building decoration cost.
Only by fundamentally solving three key problems of ventilation, lighting and fire fighting of each room in the deep part of a small-area wide-depth building, the building with a small specific surface area can land, and the energy conservation of the structural super building can be realized.

And a heat exchanger is also arranged in the shell and is connected with a circulating unit for providing a heat exchange medium for the heat exchanger. In the present embodiment, the fan coil 22 is an indoor unit of a split air conditioner, and the indoor unit and an outdoor unit of the air conditioner are connected to form a refrigerant circulation circuit. Under the action of the fan 223, air enters the housing from the air suction opening 222, passes through the heat exchanger, and is discharged from the air outlet 221. The embodiment does not limit the specific type of the split air conditioner, such as a central air conditioner, a split air conditioner, or a combination of the central air conditioner and the split air conditioner, for example, the fan coil is a wall-mounted unit, a cabinet unit, a concealed fan coil or an exposed fan coil; the outdoor unit is a water machine outdoor unit of a central air conditioner or an outdoor unit of a split type air conditioner, and each indoor unit and each outdoor unit can be randomly combined.

The fresh air system sent into the fresh air room by using the secondary negative pressure provided by the embodiment combines the fresh air system with the household central air-conditioning system as a basis, expands the functions of the tail end of the household central air-conditioning system, namely the fan coil 22 of each room, and is used as power for internal circulation of the room air-conditioner and relay power for fresh air replacement of the room, so that the internal circulation and the fresh air replacement are 'dual-purpose' of one machine; in the embodiment, a rigid fresh air connecting pipe between an air supply space such as a living room passageway and an air suction opening 222 of the room fan coil 22 is not arranged, so that the space arrangement freedom degree of the room fan coil 22 is kept; in the room of the present embodiment, the fresh air port 24 can be provided with an air door, when the air door is opened, the internal circulation and the fresh air replacement are performed for two purposes, and when the air door is closed, only the internal circulation is performed; in the embodiment, it is required to establish a proper spatial relative relationship between the room fresh air inlet 24, the air suction opening 222 of the fan coil 22 and the room air return opening 231, that is, it is required that the room fresh air inlet 24 and the air suction opening 222 of the fan coil 22 are arranged close to each other, and the room fresh air inlet 24 and the room air return opening 231 are arranged far away from each other, that is, the distance of air circulation between the room fresh air inlet 24 and the air suction opening 222 of the fan coil 22 is smaller than the distance of air circulation between the room fresh air inlet 24 and the air return opening 231 of the room air return pipe 23.
When the internal circulation of the fresh air system sent into the fresh air room by using the secondary negative pressure provided by the embodiment operates, the fan coil 22 starts to operate, the fan 223 boosts the pressure of the sucked indoor air and flows through the heat exchanger to cool and dehumidify (or heat and raise the temperature), then the air is emitted from the air outlet 221 of the fan coil 22 at a high position, is reflected by the opposite wall (and/or door and window) of the room and then flows back to the wall on the side where the fan coil 22 is located, and the air at the lower part of the room is pressed to be supplemented into the fan coil 22 from the air suction port 222 of the fan coil 22, and then the next circulation is started. Air pressure distribution in room air conditioner internal circulation: the air flow pressure at the upper part of the room is high, the air flow pressure at the lower part of the room is low, the air flow pressure at the air outlet 221 of the fan coil 22 is highest, and the air flow pressure at the air suction port 222 of the fan coil 22 is lowest.
In the fresh air replacement operation of the fresh air system sent into the fresh air room by using the secondary negative pressure provided by the embodiment, the air door 21 of the fresh air opening 24 of the room is opened, the dirty air in the room is pumped and exhausted by the return air opening 231 of the room, the fan coil 22 of the room operates, the return air opening 231 of the room generates the primary negative pressure in the room, the air suction opening 222 of the fan coil 22 generates the secondary negative pressure on the basis of the primary negative pressure generated by the suction of the return air opening 231 of the room, so that the air suction opening 222 of the fan coil 22 is positioned in the lowest pressure area of the room, a large pressure difference is formed between the adjacent fresh air opening 24 of the room and the air suction opening 222 of the fan coil 22, the fresh air is pulled to rapidly flow into the room and is sucked by the air suction opening 222 of the fan coil 22, the pressure is boosted and then is ejected at a high speed from the air outlet 221 of the fan coil 22, the ejected fresh air flow is reflected by the opposite wall and then flows back to the side of the inner wall where the door is positioned, the dirty air in the room is pressed into the return air opening 231 of the negative pressure room which is far away from the fresh air opening 24 of the room, the high-efficiency bidirectional flow fresh air replacement effect of the room is formed, as shown in fig. 6 to 7.
The room fresh air system 2 is a fresh air system which utilizes secondary negative pressure to send fresh air into a fresh air room, the distance between the room fresh air inlet 24 and the air inlet 222 of the room fan coil 22 is close to the distance between the room fresh air inlet 24 and the air return inlet 231 of the room air return pipe 23, namely, the distance between the room fresh air inlet 24 and the air inlet 222 is smaller than the distance between the room fresh air inlet 24 and the air return inlet 231 of the room air return pipe 23, the secondary negative pressure generated by suction of the air inlet 222 of the fan coil 22 close to the room fresh air inlet 24 on the basis of primary negative pressure generated by suction of the room air return pipe 23 is effectively utilized, the air inlet 222 of the fan coil 22 is positioned in the lowest pressure area of the room, the maximum pressure difference is formed between the close room fresh air inlet 24 and the air inlet 222 of the fan coil 22, fresh air at the door is driven to rapidly flow into the room, and is sucked into the air by the fan coil 22 to accelerate pressure rise and shoot to the opposite wall surfaces of the room, the dirty air in the room is pushed to enter the air return pipe 23 of the room after being reflected by the opposite wall surface and then flows back to the lower part of the room, thereby increasing the air stirring of the room and eliminating the ventilation blind area.
When the room fresh air system 2 carries out room fresh air replacement, the room 1 is wholly presented with negative pressure because the room air return pipe 23 sucks air, so that the negative pressure of the air suction port 222 of the fan coil 22 is lower than that in internal circulation, the pressure difference between the inside and the outside of the room is larger, the power for the fresh air outside the room to flow into the room is larger, and the room fresh air is favorably introduced. Fresh air outside the room flows into the fresh air in the room from the fresh air inlet 24 of the room, is sucked by the suction inlet 222 of the fan coil 22 nearby, is boosted and discharged, obtains high kinetic energy and is emitted to the opposite wall surface by a dynamic pressure head, and flows back to the lower part of the room after being reflected by the opposite wall surface to push dirty air in the room to flow to the air return inlet 231 of the air return pipe 23 of the room.
The fresh air system 2 for sending fresh air into a fresh air room by using secondary negative pressure provided by the embodiment is mainly characterized in that a primary negative pressure is generated in the room by pumping and discharging the air return opening 231 (namely, the room air return opening 231) of the room air return pipe 23, a secondary negative pressure is generated by the air suction opening 222 of the fan coil 22 on the basis of the primary negative pressure generated by the room air return opening 231, the two negative pressures are superposed to enable the air suction opening 222 of the fan coil 22 to be in the lowest pressure area of the room, a large pressure difference is formed between the closely arranged room fresh air opening 24 and the air suction opening 222 of the fan coil 22, and fresh air is pulled to rapidly flow into the room, as shown in fig. 8.
In fig. 8, the arrow lines from left to right are the upper air flow direction of the room, and the arrow lines from right to left are the lower air flow direction of the room; the corresponding solid line which inclines downwards from left to right above the transverse shaft is the pressure distribution of the airflow at the upper part of the internal circulation room, and the corresponding solid line which inclines downwards from right to left below the transverse shaft is the pressure distribution of the airflow at the lower part of the internal circulation room; the dotted line which is inclined downwards from left to right above the corresponding transverse shaft is the pressure distribution of the airflow at the upper part of the fresh air replacement room, and the dotted line which is inclined downwards from right to left below the corresponding transverse shaft is the pressure distribution of the airflow at the lower part of the fresh air replacement room.
Obviously, during the replacement of the fresh air, the air suction opening 222 of the fan coil 22 generates secondary negative pressure on the basis of the primary negative pressure generated by the room air return opening 231, the two times of negative pressure are superposed to enable the air suction opening 222 of the fan coil 22 to be located in the lowest pressure area of the room, a large pressure difference is formed between the closely arranged room fresh air opening 24 and the air suction opening 222 of the fan coil 22, and the fresh air is pulled to rapidly flow into the room 1.
