Description
Technical Field
The invention belongs to a building ventilation system, and particularly relates to a whole-house fresh air system with a fan coil arranged adjacent to an outer wall.
Background
Air, which is a vital element that every living body of our human beings can not leave every quarter hour; our dependence on air, and even on all other vital elements, including food and water. Most of our lives in houses, in essence, in indoor secondary air environment enclosed by house walls and floor slabs. Carbon dioxide and excrement generated by human body metabolism, oil smoke generated by kitchen cooking, water vapor evaporated by bathing, benzene and formaldehyde volatilized from indoor decoration materials and the like cause indoor air to be polluted, and release huge demands of people on house ventilation and improvement of indoor secondary environment quality.
Our living space requires continuous, stable, high quality replacement of fresh air, but residential ventilation is not equal to opening doors and windows. In winter and summer with quality indexes such as air temperature and humidity deviating from normal values, in weather periods such as haze days, sand-blown days, south returning days, plum rainy seasons and the like, in windless periods when the atmosphere is in a static state, and in epidemic prevention periods when viruses frequently abuse and need to increase indoor ventilation, mechanical ventilation equipment is needed to carry out concentrated filtration, temperature reduction and dehumidification (heating and temperature rise) on fresh air, fresh air flow with appropriate temperature, humidity, cleanliness and freshness is input, secondary environment quality in a sleeve is improved, and the living ideal that 'the quality from nature is higher than nature' is realized.
However, in order to meet the demand of fresh air for a house, a simple fresh air system is assembled on a new building, a PVC air supply pipeline for communicating each room is mostly arranged on an air supply fan module and a suspended ceiling, the PVC air supply pipeline is in a blind-bowel type unidirectional flow, and the actual effect of bidirectional flow of fresh air pressurized feeding and dirty air negative pressure collection and discharge synchronous operation is not achieved; because the processing precision of present door and window is very high, the gas tightness is very good, and does not have room door and window to open the cooperation dirty wind just can not go out, and the new trend also can not come into. The cecum type unidirectional flow fresh air system in the building deviates from the basic principles of three-stage ventilation and bidirectional flow, and causes the problems that the dirty air in a room cannot be discharged, the fresh air cannot be fed, and the condensation on the inner wall of a fresh air supply pipe adheres to dust bacteria microorganisms to become a culture medium to cause secondary pollution.
In fact, in the design and construction process of the house, the inner wall, the outer wall and the doors and windows divide the originally spacious and open complete house space into a plurality of functional units such as a living room, a bedroom, a study room, a kitchen, a toilet and a storage room, and the functional space units are difficult to achieve natural ventilation with the outdoor environment and even difficult to operate even with forced ventilation.
The residential structure of Chinese residents is different from that of European villas; the basic properties of low floor height, multiple inner walls and small unit spaces are the starting points of the design of mechanical ventilation systems of Chinese residences: under the condition of the current situation that the floor height is 3000mm, two sets of pipelines for feeding fresh air and discharging dirty air cannot be installed, and the building area can not be reduced by 10% by increasing the floor height by 300mm to 3300 mm; and because two sets of pipelines for bidirectional flow and air supply and exhaust, a fresh air module and an air exhaust module are additionally arranged, and the suspended ceiling area is additionally arranged by decorating the two sets of pipelines, the cost is difficult to digest.
Meanwhile, in the overall planning design of a residential fresh air system, the problems of residential fresh air replacement for improving the quality of secondary environment in a building are solved, the problems of self energy consumption of a ventilation project and air conditioner energy consumption directly related to fresh air replacement need to be concerned, and the ventilation and air conditioner energy consumption becomes a main body of building energy consumption.
The building energy consumption (about 10 hundred million tons of standard coal equivalent) in China accounts for 22% of the total social energy consumption, and is parallel to industrial energy consumption and traffic energy consumption to become three swords of the total social energy consumption; and as the residential conditions are improved and the city is updated, the building energy consumption and the proportion are further improved, and the carbon peak carbon neutralization is the focus of carbon peak carbon neutralization in China and the world.
In recent years, the building energy-saving technology is extremely rapidly developed, diversified and general in forest, but can be classified into three types of building material energy saving, equipment process energy saving and building structure energy saving:
building materials are energy-saving, for example, a wall body is built by adopting hollow bricks and foamed cement bricks, an external wall surface of a building is paved by adopting rock wool boards and polyurethane foamed boards, and the like, and the heat insulation performance of the hollow bricks, the foamed cement bricks, the rock wool boards and the polyurethane foamed boards is utilized to block the transmission of heat inside and outside the wall body so as to reduce the energy consumption of the building;
secondly, energy is saved in equipment and process types, for example, a residential air conditioner adopts an independent temperature and humidity adjusting mode, and the indoor temperature is properly increased under the condition of reducing indoor relative humidity and maintaining body feeling comfort level so as to reduce the indoor and outdoor temperature difference and reduce heat leakage and air conditioner energy consumption; the heat pump hot water unit and large-area ground wall capillary radiation heating are adopted, so that the water temperature is reduced, and the heating energy efficiency of the heat pump is improved; the building vertical lifting system adopts an intelligent elevator pulled by a variable frequency motor and the like, and the technical process of optimizing residential energy equipment is improved so as to realize the residential manufacturability energy saving;
thirdly, structural energy conservation, for example, a thermal bridge cut-off aluminum alloy door and window is adopted, and a heat insulation nylon connecting piece is embedded between the inner layer aluminum alloy frame and the outer layer aluminum alloy frame to block heat conduction between the inner layer aluminum alloy frame and the outer layer aluminum alloy frame; the point type dwelling houses are reduced, the structural design of the bar type dwelling houses is greatly popularized, the external wall area and the specific surface area of the dwelling house building are reduced, the energy exchange intensity inside and outside the dwelling house is reduced, the energy consumption is reduced, and the like, and the structural energy conservation of the building is realized by optimizing the structure of the building structure or building parts;
among the three types of building energy-saving technologies, the first type of building material energy-saving technologies such as wall heat preservation and hollow glass have been widely applied to obtain very excellent technical effects, and the space for improving the energy-saving effect by continuously improving the heat insulation performance and the thickness of the building material is very narrow; the second type of residential energy equipment is technically energy-saving, the technology is relatively complex, and through the hard efforts of Chinese engineers, the residential energy equipment such as elevators, air conditioners, water heaters, cooking utensils and the like is taken as the representative of 'Chinese building', and the energy-saving level of the residential energy equipment is popular in the world; the third type of structural energy conservation is to reduce the area of the outer wall and the specific surface area of the residential building through the optimization of the building structure and reduce the indoor and outdoor heat transfer temperature difference through the optimization of the space relation of building components, thereby realizing the structural energy conservation of the building and greatly improving the space.
The basic attributes of low-rise height, multiple inner walls and small unit spaces of Chinese residential houses are taken as starting points, the problems of path, power and efficiency of fresh air replacement and the problems of ventilation and building energy conservation are focused, the two problems of fresh air replacement and building energy conservation are effectively solved through the optimization of building components, particularly the relation between electromechanical components and buildings, and the method is a major mission and a difficult task in real estate industry, building design industry and fresh air conditioning industry.

In this embodiment, the public space 6 or the outer wall of the second room is provided with a total air inlet, the fresh air module 1 is disposed on the total air inlet, and the fresh air module 1 includes a fresh air blower. The outer wall of any room or public space 6 is provided with a general air outlet, the air exhaust module 2 is arranged on the air outlet, and the air exhaust module 2 comprises an air exhaust fan.
The fan coil 4 in the room is arranged adjacent to the outer wall 52 and is judged based on the following building physics analysis: the energy consumption of air conditioning and heating in summer and winter is the main body of building energy consumption; the heating energy consumption of the air conditioner is essentially caused by heat exchange inside and outside the building; the heat exchange inside and outside the building relates to 3 heat exchange stages of indoor side air convection, outer wall heat conduction and outdoor side air convection, so that the calculation and control of the heat exchange inside and outside the building are very complicated.
Heat exchange power Q between ambient atmosphere and indoor space 1 Outer wall surface with total heat transfer coefficient K x inside and outside the outer wallBuilding S x a wall internal and external heat transfer temperature difference delta T as K x S x delta T;
the calculation formula of the total heat transfer coefficient K inside and outside the wall body is as follows:
wherein alpha is 1 Is the heat transfer coefficient of the air outside the wall, alpha 2 The heat transfer coefficient of the air at the inner side of the wall body, b the thickness of the wall body and lambda the heat transfer coefficient of the wall body.
Referring to fig. 7, the middle part in fig. 1 is an outer wall, the left side is an external environment, the right side is an indoor space, and when the ambient atmospheric temperature is higher than the indoor temperature, outdoor heat is transferred to the indoor space along the three-section relay in the heat flow direction in fig. 1:
1. external hot air convection heat transfer area of outer wall body
The first section is a hot air convection heat transfer area outside the outer wall, and the convection heat transfer coefficient is alpha 1 The hot air forms a laminar bottom layer F near the wall surface of the outer wall 1 -F 1 And the hot air flows through the convection to the laminar bottom layer F 1 -F 1 And (4) heat leakage.
2. External wall heat conduction
The second section is wall heat conduction, the thickness of the wall is b, the heat conduction coefficient is lambda, and the external hot air laminar flow bottom layer F is conducted in a heat conduction mode 1 -F 1 The heat is conducted to the indoor cold air laminar bottom layer F through the wall body 2 -F 2 ；
3. Indoor cold air convection heat transfer area

When the ambient atmospheric temperature is lower than the indoor temperature, the heat is transmitted from the indoor to the outdoor in a three-section type relay manner along the heat flow direction, the principle of heat exchange between the indoor and the outdoor of the building is the same, and the heat flow direction is opposite:
1. indoor hot air convection heat transfer area
The first section is an indoor hot air convection area, and the convection heat transfer coefficient is alpha 2 The hot air forms a laminar bottom layer F near the inner surface of the outer wall body 2 -F 2 Indoor hot air flows through convection to the laminar bottom layer F 2 -F 2 And (4) heat leakage.
2. External wall heat conduction
The second section is wall heat conduction, the wall thickness is b, the heat conduction coefficient is lambda, and the indoor hot air laminar flow bottom layer F of the inner wall surface of the wall is conducted by heat conduction 2 -F 2 The heat is conducted to the cold air laminar bottom layer F on the outer wall surface 1 -F 1 ；
3. External cold air convection heat transfer area of outer wall body
The third section is an external cold air convection heat transfer area of the external wall, and the convection heat transfer coefficient is alpha 1 The cold air forms a laminar bottom layer F near the wall surface of the outer wall 1 -F 1 And a laminar bottom layer F 1 -F 1 The heat leakage from the room is transferred to a remote place by the convection of cold air.
Although the three-stage heat leakage process from outdoor hot air in summer to indoor through an outer wall or from indoor hot air in winter to outdoor through an outer wall is complex, in a formula of Q (heat exchange strength) ═ K (total heat transfer coefficient) × S (outer wall area) × Δ T (internal and external temperature difference), only the component factors and the interrelation of K are complex, and the mathematical structure complexity and the calculation complexity of K do not change the simple mathematical relationship that "the heat exchange strength Q is in direct proportion to the outer wall area S and the external and internal temperature difference Δ T of the outer wall".

The same physical analysis of the building is compared with the physical analysis of the building, which is suitable for the heating operation of the fan coil in the room in winter:
if the ambient temperature is 5 ℃, the air outlet temperature of a traditional deeply-arranged room fan coil during heating operation is 45 ℃, the temperature of vertical sinking air flow blown to the inner side of the outer wall 52 is near 35 ℃, the temperature of return air is about 21 ℃, and the indoor and outdoor temperature difference of the outer wall 52 is 35-5-30 ℃, indoor air leaks outdoor heat Q through the outer wall 1 ＝K×S×⊿T 1 ＝30K×S。

In this embodiment, there is no limitation on where the central air duct 24 and the exhaust fan 22 are specifically disposed in a room group in a building, for example, the central air duct 24 and the exhaust fan 22 may be disposed in a kitchen, a balcony, a toilet, a bedroom, a storeroom, a living room, a passageway, etc., taking the case where the exhaust fan 22 is disposed in the kitchen and the central air duct 24 is disposed in the passageway, since a cross beam is disposed between the kitchen and the passageway, the rear end air duct 23 communicating the central air duct 24 and the exhaust fan 22 should pass through the cross beam, if only one rear end air duct 23 is disposed between the exhaust fan 22 and the central air duct 24, the diameter of the rear end air duct 23 is relatively large, and a hole formed in the corresponding cross beam for the rear end air duct 23 to pass through is relatively large, and the integrity and the strength of the cross beam is damaged. Therefore, in this embodiment, it is preferable that the exhaust fan 22 and the central air duct 24 are connected by two or more thin rear-end air ducts 23 with smaller diameters, and correspondingly, the cross beam is provided with a plurality of small holes adapted to the plurality of thin rear-end air ducts 23, and the plurality of thin rear-end air ducts 23 pass through the plurality of small holes respectively. Specifically, the exhaust fan 22 is provided with two or more exhaust openings, and each exhaust opening is connected with the central air duct 24 through a rear air duct 23.
If the exhaust fan 22 is installed on a balcony, the balcony is communicated with the outside, so that the exhaust outlet of the exhaust fan 22 does not need to be communicated with the outside through an exhaust duct. If the exhaust fan 22 is installed in a room with an outer wall, an exhaust outlet of the exhaust fan 22 is communicated with the outside through the exhaust duct 21.

The whole-house fresh air system provided by the embodiment is an integrated innovation on the basis that the room fan coil is arranged adjacent to the outer wall, and has the advantages of very distinct technical and economic comparison:
1. extremely optimized whole-house fresh air replacement path
The whole-house fresh air system adopts a whole-house bidirectional-flow fresh air conditioning system, a plurality of small rooms in a sleeve are turned towards a pocket, under the premise that only one set of air pipe is arranged in the sleeve, no barrier exists behind a front door of a digging room and the resource endowment of an air flow channel is provided, fresh air sent out by a balcony fresh air module is directly supported to each room door head by means of a living room passageway through ductless air supply, is sucked by secondary negative pressure of a room fan coil arranged in the room and adjacent to an outer wall through an electric air door opened on the door head, is shot to the inner wall of the room by a room fan coil 'gravitational slingshot', is blocked by the inner wall to return, drives dirty air in the room to spirally flow into a return air inlet of a far-angle room return air pipe of the room, enters a negative-pressure central air pipe, and is sucked by a fan to boost and exhaust outdoors.
In the embodiment, a whole-house bidirectional-flow fresh air conditioning system is adopted, and an extremely optimized fresh air replacement path is formed by linking environmental fresh air → a fresh air module → a living room passageway replacing an air supply pipe → fresh air ports of all rooms → a room fan coil → an inner wall → a room air return pipe → a central air pipe → an air exhaust fan → environmental atmosphere, and the linkage is formed into a complete air supply and exhaust bidirectional-flow air flow organization form comprising three stages of supply, replacement and exhaust. In spring and autumn with proper temperature and humidity of the environment air, short circuit can be implemented on the fresh air module, fresh air passes through the living room from the balcony screen door and directly enters the passageway and then turns into the room, and the process is simplified.
A full-house bidirectional flow fresh air conditioning system is characterized in that a room air path consisting of a room fresh air port → a fan coil → an inner wall → a room air return pipe of each room is connected in parallel on a house ventilation main path which mainly comprises three stages of feeding, replacement and discharging and is mainly combined by feeding and discharging, so that the old and difficult problem of short circuit of fresh air in the room is solved; all rooms in the set comprise toilets, and all the rooms enjoy 'flood irrigation' type fresh air replacement, and the whole-room fresh air replacement has no blind area and no dead angle.
2. Fully compatible fresh air replacement power
The whole-house bidirectional-flow fresh air conditioning integrated system of the embodiment is based on a current household central air conditioning system, and exploits the potential energy of a room fan coil to serve as the whole-house total fresh air module power and the room fresh air relay power.
The combined fresh air module arranged in the living room implements compatibility twice: because the fresh air fan coil is installed close to the balcony door instead of the traditional deep part of the living room, the structural reversal of the temperature field of the living room realizes 'transition energy saving' and brings the reduction of the heat load of the living room, 2 fresh air fan coils (originally split into 2 for reducing noise) of the traditional living room are combined into 1, then the air conditioning treatment of the fresh air sent by the balcony air inlet boosting device is combined with the circulation function in the living room again, and 'same-machine air conditioning' is implemented; the combined fresh air module adopts a large-size fan coil (FP102 and above) or a FP102 heat exchanger and a FP85 fan to be recombined to form a fresh air fan coil, which is just matched with the large-load energy requirement of fresh air conditioning treatment in summer and winter; the air inlet booster device fan is connected with the fresh air fan coil fan in series, the whole-process power dispersion of fresh air filtration and air conditioning treatment is realized, the working pressure difference of the fan coil is effectively reduced, and the noise of a living room is inhibited. After the fresh air module and the fan coil are subjected to 2 times of functional recombination and 1 time of spatial recombination to form the combined fresh air module, the traditional double-fan coil is reduced before the fresh air conditioning equipment, the installation cost and the operation cost of a living room are compared.
The room fresh air system sets the room fan coil into the relay power of room fresh air replacement on the premise of not increasing the independent air supply pipeline and the power equipment: a room fresh air electric air door is arranged by depending on a room door leaf (or the upper part of a door frame), the secondary negative pressure function of an air suction port when a room fan coil runs is developed on the basis of room primary negative pressure generated by a whole room exhaust system for pumping and exhausting dirty air in a room, the air suction port of the fan coil becomes the lowest air pressure area of the room, the maximum pressure difference is generated inside and outside the door leaf electric air door to pull aisle fresh air to flow into the room, the aisle fresh air is shot to an inner wall by the 'gravity slingshot' of the fan coil and is blocked by the inner wall to return to the main space of the room, the dirty air is driven to flow into a fan air return port, the problem of the short circuit of the fresh air in the room is solved, in addition, the fresh air replacement power is fully compatible with the internal circulation air conditioner power, and the potential of the room fan coil is deeply developed.
3. Perfect fresh air replacement efficiency
When the whole-house bidirectional-flow fresh air conditioning system executes fresh air replacement, introduced outdoor fresh air is firstly filtered in an air inlet and pressure rising device and then enters a large fresh air fan coil (FP102 or more) of a living room for air conditioning modulation, wherein the air conditioning modulation comprises cooling and dehumidifying in summer and heating and warming in winter, and the introduced outdoor fresh air becomes high-quality fresh air with the freshness, cleanliness and temperature and humidity reaching standards and is then sent to a passageway of the living room in a set to directly reach the door heads of all rooms; when the fresh air runs, the air output of the balcony air inlet boosting device is more than or equal to the low-speed running air quantity of the fresh air fan coil in the living room, the circulating air quantity in the fresh air fan coil in the living room is reduced to zero, the balcony fresh air is not mixed with the dirty air in the living room, the fresh air blown out by the fresh air fan coil is propelled to the main space of the living room and the connecting passageway in a laminar flow mode, and the dirty air in the passageway of the living room is driven to be discharged outside through the air return opening of the air return pipe of the public washroom; the passage of the living room has large circulation section, low flow velocity and small fresh air flow resistance, thereby reducing the energy consumption of fresh air transportation;
when the fresh air in the room is replaced, in order to reduce the mixing of the fresh air and dirty air in the room and reduce the air age of the room, staggered fresh air replacement in different rooms is implemented to increase the air passing amount of the room in a fresh air replacement state, so that the air passing amount is close to the low-speed running air amount of a fan coil in the room, partial internal circulating air amount possibly existing in the fan coil during the fresh air replacement in the room is reduced, the fresh air ejected by the gravitational slingshot of the fan coil in the room is pushed to the inner wall in a laminar flow mode and then is folded to an air return opening, and the fresh air replacement efficiency of the room is improved.
The central air pipe exhaust system is arranged above the passageway, collects the dirty air of the return air pipes of each room from two ends, flows to the waist air outlet and then flows through 2 small-diameter beam-penetrating air pipes to be delivered to the exhaust fan; the wind paths are networked in parallel, the sectional area of the wind pipe is enlarged, the flow speed is reduced, the resistance is reduced, and the air exhaust energy consumption and the noise are greatly reduced.
In the embodiment, the energy consumption of full-house bidirectional flow fresh air replacement adopts a three-stage link conveying mode of ' fresh air positive pressure feeding + fan coil gravitational catapult + dirty air negative pressure pumping and discharging ', and according to ' 1 day, 4 times of fresh air replacement, 45min at each time and 400m of ventilation quantity at each time of a large-dwelling house 3 And performing measurement and calculation by comprehensively scanning and replacing once: the fresh air module and the exhaust module adopt an outer rotor centrifugal fan YWF-B2S-220-065AB00, 540m 3 H, power 80 w; the fan coil pipes of the living room and the room adopt FP102 and FP51 respectively, and the fresh air replacement air volume is 540m and 270m respectively 3 The motor power is 54 and 98w respectively, and 2 room fan coils are operated simultaneously when the fresh air in the set is replaced in a partitioning manner; the linked three-stage pressurized transmission of 'fresh air positive pressure feeding + room fan coil relay power + dirty air negative pressure pumping' is that the total power of a fan is 2 x 80+2 x 54+1 x 98 ═ 366w, the total time is 3 hours after 4 times of operation in the whole day, the average value of 24 hours in the day and the night is 45.75w, and the fresh air replacement power consumption in the whole day is 1.1kwh (excluding the operation energy consumption of an air conditioner host). Compared with the air-conditioning (heating) load of a whole set of dwelling houses at about 15kw and the 5kw electric power load of an air-conditioning (heat pump) host in winter and summer, the energy consumption average value of the whole-house bidirectional-flow fresh air replacement is 2 orders of magnitude lower than that of the whole-house bidirectional-flow fresh air replacement, and the energy consumption is greatly lower than that of the building reduced by 'transition energy conservation' of a fan coil in a living room and can be ignored.
4. Super-large-amplitude building energy conservation
The whole room two-way flow fresh air conditioning system of this embodiment has continued all functions of air conditioner to with traditional room fan coil room deep setting mode, the innovation sets up the position than adjacent outer wall, and the novel structural relation of innovation air conditioner and building changes the indoor temperature field distribution, reduces the inside and outside difference of temperature delta T of outer wall, thereby reduces indoor outer heat exchange strength Q and building energy consumption.
Because, the heating energy consumption of the air conditioner is essentially originated from the heat exchange inside and outside the building; the heat exchange inside and outside the building relates to 3 heat exchange stages of indoor side air convection, outer wall heat conduction and outdoor side air convection, so that the calculation and control of the heat exchange inside and outside the building are very complicated; however, in summer and winter, the calculation and control of the heat exchange between the inside and the outside of the building are complicated, in a formula of Q (heat exchange strength) ═ K (total heat transfer coefficient) × S (outer wall area) × Δ T (inside-outside temperature difference), only the component factors and the interrelation of K are complicated, and the structural complexity and the calculation complexity of K do not change the simple mathematical relationship in which the heat exchange strength Q is proportional to the outer wall area S and the inside-outside temperature difference Δ T of the outer wall.
In the traditional air conditioner installation project, a room fan coil is usually arranged at the deep part of a room relative to an outer wall, by taking the example of cooling operation under the standard working condition of an air conditioner in summer, the room fan coil arranged at the deep part of the room sucks room return air at about 27 ℃ to cool and dehumidify, then cold air flow at about 14 ℃ after cooling and dehumidifying passes through the upper space of the room and blows to the outer wall, and the cold air flow is blocked and reflected by the outer wall, flows back to the lower part of the room fan coil at the deep part of the room from the middle lower space of the room, is sucked again by the room fan coil to cool and dehumidify, and starts a new cycle of circulation; in the internal circulation process of the air conditioner, the process of blowing out and refluxing the cold air flow of the room fan coil is a process of gradually enlarging the air flow section, gradually attenuating the air flow speed and gradually increasing the temperature, and the temperature increase of the air flow mainly occurs in the process of refluxing the air flow from the outer wall to the suction inlet of the room fan coil.
If the ambient temperature is 32 ℃, the air outlet temperature of a traditional deep-arranged room fan coil during the refrigerating operation is 14 ℃, the temperature of air blown to the inner side of an outer wall and then vertically sinking is near 19 ℃, the temperature of return air is about 27 ℃, the indoor and outdoor temperature difference at the outer wall is 32-19 ═ 13 ℃, and then the indoor heat Q1 ═ KxS × (delta) T1 ═ 13 KxS is leaked from the outdoor environment through the outer wall.
The room fan coil innovation setting that this embodiment set up traditional deep is than the position of adjacent outer wall, creates the novel structural relation of air conditioner and building, and the indoor temperature field changes thereupon, and the inside and outside difference of temperature delta T changes thereupon in the outer wall to indoor outer heat exchange intensity Q and building energy consumption change thereupon.
The same environment temperature is 32 ℃, in the same room structure, according to the present embodiment, the outlet air temperature of a room fan coil arranged adjacent to an outer wall during cooling operation is 14 ℃, the temperature of air flow blown to the deep part of a room and then vertically sinking is near 19 ℃, the return air temperature of the outer wall is 25 ℃, the temperature of a fresh air inlet of the room fan coil is 27 ℃, the indoor and outdoor temperature difference of the outer wall is 32-25 ═ 7 ℃, and then indoor heat Q2 ═ K × S × T2 ═ 7K × S leaks into an outdoor environment through the outer wall; compared with the scene of arrangement of the deep part of the fan coil of the room under the structural relation of the traditional air-conditioning building, the reduction range of the heat leaked into the room (Q1-Q2)/Q1 is 46 percent in proportion to (13-7)/13.
5. Extreme cost performance
If the bidirectional pipeline bidirectional flow fresh air standard of a public building is executed, the floor height of the house needs to be increased by 300mm to 3300mm to solve the problem of air supply and exhaust 2 sleeve pipeline space interference, the building area of the building is reduced by 10 percent, the loss of real estate development projects is directly caused, and the building has an intolerable weight for real estate enterprises; meanwhile, each house is additionally provided with 2 sets of pipeline pipe valves for air supply and exhaust, 1 fresh air module and 1 exhaust module, the equipment cost is 5080 yuan (2 sets of pipelines are multiplied by 1000 yuan/each set of pipelines, 12 air door air valves are multiplied by 140 yuan/one plus central control large screen 800 yuan + fresh air module 800 yuan + exhaust module 800 yuan), the installation cost is 2140 yuan (50% of the equipment cost of 2 sets of pipelines, 12 air door air valves, fresh air modules and exhaust modules), and the total amount is 7220 yuan.
The embodiment adopts a full-house bidirectional flow fresh air conditioning system, and achieves extremely-low cost performance based on innovation of 'transition energy saving', 'same-unit air conditioning', 'ductless air supply', 'gravitational slingshot' and 'central air duct exhaust': on the basis of a 130 square meter house type structure and a house type central air conditioning system, only 6 room fresh air port electric air doors, 5 return air pipe electric air valves and 1 set of air exhaust pipelines are added, the equipment cost is increased by 3400 yuan (11 air door air valves are multiplied by 140 yuan/one plus a central control large screen 800 yuan plus an air exhaust fan air pipe 1000 yuan), the equipment cost of fresh air in the whole process is increased by about 850 yuan (50% of the equipment cost of 5 return air pipe electric air valves and 1 set of air exhaust pipe fans), the equipment cost is increased by 4250 yuan in total, and a set of full-house bidirectional flow fresh air conditioning system which has high quality and high efficiency and greatly saves space resources is obtained.
