Description
Technical Field
The utility model relates to a ventilation technology field in the building, in particular to adopt flat row's of sending new trend system building.
Background
Under the traditional building design specification, 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 north-south permeability of the building is realized, the outward window of a kitchen and a toilet is realized, and sufficient natural lighting and ventilation are ensured.
And by adopting the technical measures of multiple separated buildings, the thickness reduction of a single building, the arrangement of a special lighting and ventilating structural joint for each building and the like, the area of the outer vertical surface of each building is inevitably large, the effective building area is small, and the large specific surface area of the building is finally reflected on the index of the specific surface area.
The building group volume ratio is the ratio of the total floor area of the building group to the total floor area, and reflects the space utilization coefficient and the degree of congestion. The specific surface area of a building is the ratio of the total external surface area of the building to the total building area, and is a core index reflecting the energy characteristics and the structural characteristics of the building. The large specific surface area of the building is one of the root causes of large external surface area of the building, large shared external surface area of unit building area of living space, high building energy consumption, high external wall material consumption, complex construction process, low overall volume ratio of building groups and high house price.
A high-price enterprise and a high-energy consumption enterprise of a residential building are two major problems of scaling problems in the real estate industry.
The pushing of the high-rate enterprises is the land price, but the volume rate is the hedging factor of the room price, the low volume rate further raises the room price, and the high volume rate lowers the room price.
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 volume ratio and the specific surface area of the residential building are also hedging factors, and the volume ratio is high, 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, the exchange strength with environmental energy is low, and the energy consumption of the building is low; on the contrary, the volume fraction is low, the specific surface area of the residential building is large, the external wall surface area shared by the unit building area of the residential space is large, the energy exchange intensity with the environment is high, and the building energy consumption is high.
At present, the volume ratio index of a residential group and the specific surface area index of a residential building are constrained by the traditional planning specifications and building design specifications, 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 volume ratio of a building group is greatly improved, the specific surface area of the building is greatly reduced, and the large-scale residential building are not the second choice for solving the two problems of high house price and high energy consumption of the house which are subject to scaling in the real estate industry.
The specific surface area of the building is reduced, the volume ratio is improved, only one road is provided for increasing the three-dimensional size of the building and increasing the quantity of the building objects, and the key for determining whether the road is on or off is the ventilation problem in the building.
If the ventilation problem of the deep part of the building, namely the problems of fresh air entering and dirty air discharging, can be solved, the ideal target of increasing the three-dimensional scale of the building, increasing the building volume, reducing the specific surface area and improving the volume fraction can be realized.

Similarly, the exhaust module 24 and the fresh air module 21 have the same structure, namely, the exhaust module comprises a shell and an exhaust fan, wherein the shell is fixedly arranged on the outer side of the outer wall of the flat layer 1; an exhaust cavity is arranged in the shell, one end of the exhaust cavity is communicated with the outside atmosphere, and the other end of the exhaust cavity is communicated with the main exhaust outlet; the air exhaust fan is arranged in the air exhaust cavity. The exhaust fan sucks in the dirty air from the exhaust channel 25, so that the dirty air in the exhaust channel 25 becomes negative pressure, and the purpose is to facilitate the discharge of the dirty air to the outside of the building.
Further, new trend module 21 still includes the new trend pretreatment module that carries out the filtration to the new trend, and new trend pretreatment module specifically can be filter screen, coil pipe isotructure for the new trend that gets into the house removes dust, operation such as air conditioner, is favorable to promoting the new trend pressure head simultaneously. In this example, the fresh air module 21 sucks in fresh air from the external environment, and after dust removal, the fresh air is pressurized and sent into the main air supply channel 22 and the sub air supply channel 23 of the flat layer 1, and then the fresh air is sent into each functional space unit 11 through the air supply outlet on the rear wall of each functional space unit 11 for fresh air replacement; in each functional space unit 11, fresh air flow advances from the rear wall serving as the wall of the air supply subchannel 23 to the front wall serving as the wall of the air exhaust channel 25, and dirty air flow is extruded to an air outlet of the front wall; the dirty air discharged from each functional space unit 11 is discharged into the exhaust duct 25, collected in the exhaust duct 25, and then discharged to the outside of the building through the main exhaust outlet.
In this embodiment, the main air supply channel 22, the sub air supply channels 23 and the air exhaust channels 25 in each flat layer 1 may be constructed by brick-concrete structure.
The building adopting the flat-conveying and flat-exhausting fresh air system provided by the embodiment has the advantages that:
1. the problem of space interference among the blast pipe, the exhaust pipe and the construction beam of the fresh air system of the building is solved, and the three-dimensional efficient building, particularly the fresh air system of the building with large and ultra-large volume is constructed
The existing reinforced concrete buildings are all an assembly of a foundation, a column, a main beam, a secondary beam and a floor slab. In a building construction, the upper part of a partition wall for separating each functional space unit generally corresponds to a structural beam, a main beam or a secondary beam of a building. In order to realize ventilation without blind areas, particularly deep ventilation of buildings, a channel for feeding fresh air and discharging dirty air is constructed, and a bidirectional flow fresh air system formed by combining an air supply pipe and an exhaust pipe is generally adopted; even if the air supply pipe (exhaust pipe) is replaced by public spaces such as a passageway, the exhaust pipe (fresh air pipe) still needs to be arranged.
In the space above each functional unit under the ceiling, the contradiction between the construction beam and the exhaust duct (fresh air duct) is difficult to reconcile: if the exhaust pipe passes through the opening on the structural beam, the strength of the structural beam is reduced due to the opening; if the exhaust pipe sinks to bypass the structural beam, the suspended ceiling is pressed down, and excessive upper space is occupied; especially in large-scale and ultra-large-scale buildings, the fresh air replacement amount is increased due to the expansion of the flat floor area, so that the section of the exhaust pipe is enlarged, and the problem that the large-section exhaust pipe and the structural beam space interfere with each other is difficult to reconcile.
In the embodiment, a flat-layer fresh air module, a flat-layer air supply main channel and an air supply branch channel are adopted to horizontally supply fresh air to each functional space unit on a flat layer; the functional space units are separated from the air supply sub-channels, the air exhaust channels are arranged at intervals in a staggered mode, the air exhaust channels are used for containing dirty air exhausted during fresh air replacement of the functional space units, and the dirty air is collected and discharged to the outside of a building, so that the flat-layer fresh air replacement airflow organization of the building is smooth, and the dead knot, which is caused by spatial interference and non-adjustable structural relationship, of an air exhaust pipe of an air supply pipe of a flat-layer fresh air system and a structural beam is solved.
2. The safe reliability of the fresh air supply system is improved
The fresh air supply system comprises a fresh air module, a flat air supply main channel and an air supply sub-channel, and has the advantages of ensuring that fresh air independently operates in the processes of sucking, preprocessing and conveying the fresh air outside a building to each functional space unit, effectively preventing other harmful media from being mixed in and preventing the fresh air from being polluted;
the fresh air supply system of the embodiment is composed of the independent closed flat-layer air supply main channel and the air supply sub-channel, and the dust and the like accumulated in the air supply system during operation and shutdown are very convenient to clean and clean manually, so that the problem of dust and microorganism secondary pollution in an air channel of the air supply system can be conveniently eliminated.
3. The secondary wind and light condition index in the building is superior to the natural environment
The judgment of the value of artificial secondary environment is better than the original ecological environment in terms of specific single living conditions of human beings, and is verified for many times: the concrete multi-storey high-rise residence is superior to a cave, tap water is superior to original ecological river water and underground water, and a flushing closestool is superior to a latrine; particularly, after energy technologies such as manual fire taking, air conditioning and the like are available, food cooked at high temperature is superior to taomao blood drinking, semiconductor illumination is superior to solar radiation, air conditioning wind after cooling and dehumidification in summer is superior to ambient hot wind, and floor heating in winter is superior to field bonfire.
A space is a living room as long as the space can shield wind and rain, can provide clean fresh air, proper illumination, clean drinking water and sanitary hot water, stable electric power and network signals, and can smoothly discharge dirty air, excrement and garbage.
In the embodiment, the effects of fresh air replacement and dirty air exhaust and diffusion in the building are extremely good, so that the indexes of air temperature, humidity, oxygen content, cleanliness and the like in the secondary artificial wind and light environment in the large-volume building are better than those in the primary natural environment; and the house can be free from mosquito trouble, and new house technical products such as outdoor live-action images, airflow closed-loop dehumidification type drying heat pumps, gas-free electric kitchens, semiconductor cold light source lighting and the like can be introduced, so that secondary climate conditions and living conditions which are derived from the natural environment and are higher than the natural environment are created.

The total number of the households is 2560 households; the total number of people is 8960;
the volume ratio is 16.0; total specific surface area 0.195m2/m2；
Fresh air volume: according to 3.5 people per household, each person needs fresh air for 30m per hour3All people do not go out of all worship rooms 24 hours all the day in holidays; the cooking activity is forbidden to use gas only by using an electric heating stove, and the cooking consumption fresh air volume is calculated according to 0.5 times of the human residence fresh air volume; accordingly, the maximum fresh air demand of 24 hours in one flat layer is measured and calculated to be 24.2 ten thousand meters3I.e. 1 km3H; the maximum fresh air demand of the whole 40-storey super-large-volume residential building in 24 hours is 968 ten thousand meters3I.e. 40 ten thousand meters3/h；

according to the cop 3.0 conversion of a refrigerating device (heat pump), the power consumption of each flat fresh air pretreatment is 22.3kw, and the maximum power consumption required by the fresh air pretreatment of the whole building is 892 kw; the highest fresh air pretreatment energy consumption per day is 2.4 kwh; considering the factors of no need of refrigeration dehumidification or heating temperature rise in spring and autumn, away-from-home work of family members and the like, the annual average fresh air energy consumption is less than the upper value of 1/2, namely less than 1.2 kwh/day.
In the building adopting the flat-conveying and flat-exhausting fresh air system, the energy consumption of the air conditioner of a household is reduced besides the energy consumption of fresh air pretreatment in the operation process.
In the present embodiment, referring to fig. 1 to 5, a building with a flat-type fresh air exhaust system has a plurality of air isolation layers in a vertical direction; in the embodiment, 16 functional space unit groups formed by combining four functional space units are arranged on each flat layer, the 16 functional space unit groups are mutually independent, and a passageway, namely an air isolation passageway, exists between the 16 functional space unit groups, so that an air separation type physical structure with a plurality of vertical multi-layer flat air isolation passageways is created; in this embodiment air heat exchange process, the three kinds of modes of air convection heat transfer, heat conduction and heat radiation are all in the performance, but because the effect in the vertical a plurality of air isolation layer of building and a plurality of air isolation passageways of horizontal direction, these three kinds of heat transfer modes are all very weak to make the resident family air conditioner energy consumption compare and show to reduce in traditional house.
The air convection heat transfer of the embodiment has the advantages that the fresh air volume is still very small relative to the buildings with large volume, and each flat floor has only 1 ten thousand meters3H, i.e. 3m3The air flow speed of the fresh air inlet and the dirty air outlet is high, and the fresh air flow speed of the main space of the building is very low and is only 10-2The m/s grade is similar to that of air micelles confined in foam holes in a light foam material, the air micelles are in a static or quasi-static state, the speed is approximately zero, and the convective heat transfer of air can be ignored;
the air heat conduction of the embodiment is very weak as the air heat conduction coefficient is 0.024w/mk which is only 4.4% of 0.54w/mk of water at normal temperature; in fact, in terms of heat conduction, air is a poor heat conductor, and various foaming materials such as polyurethane foam boards, wall aerated concrete blocks and even wadded quilt have excellent heat insulation effects which are derived from air bubbles with thermal insulation in the materials;
the air heat radiation of the embodiment is weak in the air heat radiation inside the building, except that strong heat radiation (heat absorption) exists between the building facade and the ambient atmosphere due to large temperature difference in summer and winter.
Based on the analysis, the average human-average fresh air energy consumption of the building adopting the flat-conveying and flat-exhausting fresh air system is less than 1.2 kwh/day all the year around; meanwhile, the embodiment adopts a super large-volume nearly orthocubic structure, so that the energy-saving effect of the building with the extremely low specific surface area is remarkable; in addition, due to the air isolation structure of the building with the plurality of flat floors in the vertical direction and the plurality of air passages in the horizontal direction, in the operation process, the air heat convection, the heat conduction and the heat radiation in the building are weak, and in sum, the energy exchange between each household and the environment is further reduced; for each resident of each functional space unit group of each flat layer of this embodiment, indoor resident's autologous heat release and cooking heating in winter can compensate the house to the weak heat leakage of environment in order to maintain indoor temperature, summer only need with resident's autologous heat release and cooking heating and extremely low environment leak into heat and remove and can maintain indoor temperature, thereby make this embodiment resident's air conditioner energy consumption compare traditional house and show to reduce more than 3/4, its energy-conserving range and effect, the energy-conserving range and the effect that the thermal insulation performance of far away non-building material and the warm equipment performance of air conditioner improve and gain can look at its neck back.
Example 3
Only one total air supply outlet is arranged on each flat layer 1 in the embodiment 1, please refer to fig. 2, that is, the embodiment 1 adopts one fresh air module 21 to supply air (single module air supply).
However, each flat layer 1 of the present embodiment is provided with two total air supply outlets, please refer to fig. 3, that is, the two opposite outer walls of the same flat layer 1 and the flat layer 1 are respectively provided with one total air supply outlet, and two ends of the air supply main channel 22 are respectively communicated with the two total air supply outlets. The two main air supply outlets are respectively provided with a fresh air module 21, namely, the embodiment performs north-south opposite feeding (or east-west opposite feeding) and dual-module air supply.
In the fresh air replacement of this embodiment, as shown in fig. 3, the two fresh air modules 21 in the south and north of the flat layer suck fresh air from the external environment, and the fresh air is pressurized and sent into the main flat layer air supply channel 22 after being dedusted, the fresh air flows in the north and south directions, and the fresh air is sent into the air supply sub-channels 23 in the east and west directions, and then sent into the functional space units 11 through the air supply outlets on the back walls of the functional space units 11 for fresh air replacement; in each functional space unit 11, fresh air flow advances from the rear wall serving as a wall of a fresh air supply sub-channel 23 to the front wall serving as a wall of an exhaust channel 25, and dirty air flow is extruded to an air outlet of the front wall; the dirty air discharged from each functional space unit 11 is discharged into the air discharge duct 25 provided on the flat floor 1 at a distance from the functional space unit 11 with respect to the air supply branch duct 23, and is collected by the air discharge duct 25 and discharged to the outside of the building.
Because the on-way resistance of the gas flowing in the pipeline is related to the type, density, speed, viscosity coefficient, structural size of the pipeline and the like, the on-way resistance calculation is a very complicated matter. However, the on-way resistance of the air flow is always proportional to the square of the air flow speed and proportional to the first time of the pipeline length, so that the reduction of the air flow speed becomes the first choice for reducing the power consumption of the air flow conveyed by the pipeline, namely the reduction of the fan power.
In addition to all the advantages of embodiment 1, because the two inlets of the fresh air flow enter from north to south, under the condition of total fresh air volume required by the flat bed, the embodiment also has the advantages of reduced speed of the air inlet flow of the air supply main channel 22, reduced on-way resistance and reduced power consumption of the fan of the fresh air module 21.

The embodiment focuses on heat recovery of the foul air exhausted by the building, and aims to solve the problem of high-energy-efficiency heating and temperature rise of the building by supplementing fresh air in winter.
Winter exhaust air of a building has a much higher heating value (enthalpy) than winter ambient air because of the higher temperature, particularly humidity, than ambient air.
Looking at the table below, the enthalpy difference between the 1kg humid air exotherms is compared in the presence of two different humid air exotherms without condensate generation: similarly, the temperature reduction and heat release of 1kg of wet air are also in the temperature reduction range of 10 ℃, two different heat release paths without condensed water are provided, namely, the heat release amount is higher than 102.1% in 20 ℃ 80% → 10 ℃ 100% and 20 ℃ 50% → 10 ℃ 95.21%, and both of the two paths are the contribution of water vapor (humidity).
Comparison table for heat release of 1kg wet air at 10 DEG C
(20℃80％→10℃100％ FK 20℃50％→10℃ 95.21％)
The above table shows that the energy density (enthalpy) of the wet air containing water vapor during our life is determined mainly by the humidity, i.e. the water vapor content in the air, rather than the temperature of the air, which is quite unexpected for our experience.
Because of cooking, bathing, breathing of people and animals and the like in the building, the foul air exhausted by the building in winter contains a large amount of water vapor, and according to the analysis, the foul air has the characteristics of high temperature, high humidity and high energy density (high enthalpy value) in unit mass in terms of energy, and is the best source of heat required by fresh air heating and temperature rise during fresh air replacement of the building.
In this embodiment, a heat pump technology is introduced into a residential fresh air system, a set of heat recovery device 242 is arranged at a dirty air outlet of a flat layer 1, a fin tube type heat exchanger is arranged at a total air outlet of the flat layer 1, and the fin tube type heat exchanger is connected with a refrigeration compressor, a throttle valve and a water-fluorine plate type heat exchanger by pipelines to form a refrigerant closed cycle channel, so that a heat carrying system (i.e. a heat pump system and a refrigeration system) is constructed, as shown in fig. 4, large-scale heat carrying is realized between air flow at the dirty air outlet and hot water by using lower electric energy consumption of a compressor fan and a water pump, and a solution with high energy efficiency is provided for heating fresh air in winter of a building and producing sanitary hot water in a.
