Description
Technical Field
The utility model belongs to the technical field of the new trend system, especially, relate to a bathroom new trend replacement system with electronic air door.
Background
Most of our life lives in the residence, essentially in the indoor secondary air environment enclosed by the walls and the floor of the residence; carbon dioxide and excrement generated by human body metabolism, oil smoke and water vapor discharged from cooking and bathing, benzene and formaldehyde volatilized from interior decoration materials and the like cause indoor air to be polluted.
Fresh air outside the house is introduced into the house and indoor dirty air is synchronously exhausted, so that bidirectional flow fresh air replacement of the house is realized, and the house is the natural place of home life.
The ventilation problem of a plurality of closed spaces such as a bedroom, a washroom and the like formed by the inner space of the house cover separated by the outer wall of the inner wall and doors and windows is solved, and only the unique scheme of a bidirectional flow air supply and exhaust system is adopted; the 'bidirectional flow' is a basic principle of ventilation of closed spaces, namely, a wind supply pipeline is arranged to supply fresh wind to each closed space, and another set of exhaust pipeline is arranged to extract dirty air of each closed space; fresh air is fed into and exhausted from the polluted air, namely 'bidirectional flow', which are two aspects of the same problem of 'ventilation' of buildings, and are dependent on each other and lack of each other; there is no "one-way flow" fresh air replacement of practical significance.
A difficulty with residential ventilation is room ventilation. Because, even set up whole room air inlet module and exhaust module, possessed and sent the new trend to each room fresh air inlet through the living room passageway, with each room foul air through room return air duct take out outdoor condition, if room fresh air inlet does not have relay air supply power, but only rely on the air supply malleation in living room passageway and room return air duct convulsions negative pressure to realize room high efficiency new trend replacement, still impossible: firstly, the fresh air delivered to the door heads of all rooms from the passage of the living room can only be micro-positive pressure of 1pa grade but can not be micro-positive pressure of 101pa grade and 102pa grade, when the fresh air in the passage of the living room is driven by the micro-positive pressure to pass through the fresh air inlet of the room, the speed of more than 2m/s and the corresponding dynamic pressure head can not be generated, and the air flow field in the room is difficult to generate large-force stirring; secondly, the room negative pressure generated by the air exhaust module and the room air return pipe is not enough to pull the fresh air at the fresh air port of the room to generate the speed of more than 2m/s and the corresponding dynamic pressure head, and especially when the air return port of the room air return pipe is arranged at the same side as the fresh air port of the room, a serious fresh air short circuit also occurs, namely the fresh air flow entering from the fresh air port of the room does not obtain the higher dynamic pressure head to enable the fresh air flow to flow into the main space of the room, but flows straight to the fresh air port of the room along the path with the shortest distance and the smallest resistance between the fresh air port of the room and the air return pipe, thereby wasting fresh air resources and reducing the fresh air replacement effect of the room.
"the no blast pipe air supply and exhaust based on room fan coil relay power combines to arrange as main whole house bidirectional flow new trend system" that shanghai berjian heat energy science and technology limited company provided in 2021, the air supply function of development sitting room passageway replaces traditional blast pipe, develops the secondary negative pressure of each room door head fan coil and replaces relay power as room new trend and makes house new trend system and air conditioning system fuse comprehensively, is the landmark incident in the house new trend system development process.
In a whole-house bidirectional flow fresh air system based on combination of air supply pipe-free air supply and exhaust of room fan coil relay power of Shanghai Berchun thermal technology Limited, room fresh air replacement is an intermediate link and a key link of whole-house fresh air replacement and consists of a room door fresh air inlet, a room fan coil and a room air return pipe which are connected in series; the development of the secondary negative pressure function of the fan coil at the door head of the room is the key of the whole-room bidirectional-flow fresh air system.
When the fresh air in the room is replaced, on the basis of primary negative pressure generated by the suction of an exhaust system and a dirty air return pipe in the room, a secondary negative pressure is generated by an exhaust inlet when a door head fan coil operates, so that the air pressure at the door head in the room is the lowest, the maximum pressure difference is formed between a partition door head fresh air port and a fresh air area of the passageway, the fresh air in the passageway is pulled to quickly flow into the room through the door head fresh air port, the fresh air is sucked by the fan coil to be boosted and then flows to the outer wall, the air is reflected by the outer wall and then flows back to one side of the inner wall where the door is located, dirty air in the room is driven to enter the return pipe in the room, the problem of fresh air short circuit in the fresh air replacement of the room is fundamentally solved, and the fresh air replacement technology of 'secondary negative pressure', 'deep suction high discharge', 'and room replacement discharge' is given as shown in figure 1.
In the whole-house bidirectional flow fresh air system based on the combination of the air supply pipe-free air supply and exhaust of the room fan coil relay power and the exhaust as a main part, although secondary negative pressure vortexes exist at air suction ports of the fan coils in suspended ceilings in all rooms, the secondary negative pressure vortexes can become power for fresh air to flow into rooms in hallway passageways, but the system still faces the problem of how the fresh air sent into the hallway passageways crosses doors.
In a house, a door is a connection node between a room and a passageway, and has the characteristics of being opened front and back and having no barriers.
How to utilize the special position advantage of door, develop the special quality of "open around, do not have the barrier" of door, when the door is as whole room "traffic node", also become whole room "wind path node", link the three stages of "new trend is sent into", "room new trend replacement", "dirty wind discharges" of whole room bidirectional flow new trend system through the door, become an important technical problem in air conditioner heating and ventilation field and building field.
