Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of building ventilation and energy saving, and in particular to a green ventilation and air permeability device suitable for a top roof. Background Art
[0002] The top floors of modern buildings are extremely hot in the summer due to intense sunlight, with average temperatures significantly higher than those on the floors below, making the living experience less pleasant. Modern air conditioning and ventilation systems consume significant energy and generate a certain amount of noise. Because windows are typically located in the middle of a room, hot air from the top cannot be naturally and efficiently evacuated and exchanged, resulting in a poor living experience for residents on the top floors of modern buildings. Summary of the Invention
[0003] The present invention provides a green ventilation and air permeability device suitable for top roofs to solve the above-mentioned deficiencies in the technology.
[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a green ventilation and air permeability device suitable for the top roof, comprising an outdoor air exchange device, the outdoor air exchange device comprising a ventilation and air permeability pipe, the ventilation and air permeability pipe leading to each room indoors and provided with an indoor air exchange device at the end, the outdoor end and the indoor end of the ventilation and air permeability pipe respectively provided with an outdoor air exchange closing cover and an indoor air exchange closing cover, the outdoor air exchange closing cover and the indoor air exchange closing cover respectively connected to an outdoor air exchange control device and an indoor air exchange control device for controlling their opening and closing.
[0005] The outdoor air exchange control device controls whether the entire system exchanges air with the outside world, while the indoor control device controls whether each room participates in outdoor air exchange, preventing cold air from infiltrating during cold weather. This device can increase the number of indoor air exchangers, ensuring efficient air circulation in all rooms requiring ventilation. When used in conjunction with window ventilation or open windows, the convection effect is even better.
[0006] Furthermore, the outdoor ventilation device includes an outdoor ventilation hood mounted outside the outdoor end of the ventilation duct. The hood's upper surface is provided with a plurality of openings around its periphery for indoor air circulation, and its lower surface, where it contacts the building, has openings for drainage of rainwater entering the outdoor ventilation device. The outdoor ventilation hood is secured to the building with screws to prevent wind-induced movement of the device. The outdoor ventilation duct opening must be positioned higher than the opening of the outdoor ventilation hood to prevent rainwater from entering.
[0007] Furthermore, a water guide cover is provided inside the outdoor air exchange cover, and the water guide cover is sleeved outside the ventilation and air permeability pipe and is configured in a trumpet shape.
[0008] Furthermore, a rubber sleeve is installed at the contact point between the water guide cover and the ventilation pipe. The water guide cover is a trumpet-shaped stainless steel cover with a rubber sleeve installed at the contact point between the ventilation pipe and the water guide cover. A hole is reserved for the metal sleeve of the outdoor air exchange control device, and structural adhesive is applied to the contact surface to prevent rainwater from flowing in.
[0009] Furthermore, the indoor ventilation device includes an indoor ventilation cover, a filter device is provided at the bottom of the indoor ventilation cover, and the indoor ventilation cover is firmly connected to the building by screws.
[0010] Furthermore, the indoor ventilation device includes an upper half and a lower half which are hinged on one side and snap-connected on the other side. The filtering device includes a strip sieve plate opened in the lower half, and a detachable indoor ventilation filter is arranged inside the lower half.
[0011] The strip sieve plate is used to prevent larger foreign objects from entering the device. An indoor air exchange filter with denser holes is installed above (inside) the strip sieve plate to prevent smaller objects from entering the device. The indoor air exchange filter is fixed in the indoor air exchange cover through a horizontal slot. When replacing and cleaning, it can be pulled out by applying a horizontal force, making replacement convenient. The lower half of the indoor air exchange cover is connected to the upper half by a buckle and can be opened for easy inspection and replacement of the indoor air exchange filter.
[0012] Furthermore, the outdoor air exchange control device and the indoor air exchange control device include a controller. A steel wire is provided between the controller and the indoor air exchange cover / outdoor air exchange cover for connection. The steel wire is encased in a metal sleeve. The steel wire is encased in the metal sleeve and is used to connect the controller and the indoor air exchange cover / outdoor air exchange cover, thereby controlling the opening and closing of the cover and, therefore, the need for ventilation.
[0013] Furthermore, one side of the indoor air exchange closed cover is hinged to the ventilation pipe, a steel wire is connected to one hinged end, and the other end is free, and a counterweight is provided at the free end.
[0014] Furthermore, the ventilation and air permeability pipe is arranged at an angle at the end indoors, the inner side of the indoor air exchange closing cover is connected to the steel wire, and the counterweight block is arranged at the outer end.
[0015] Furthermore, the diameter of the ventilation pipe should be adjusted according to the size of the room and the number of people using it. According to existing standards, the fresh air volume of residential and office buildings should not be less than 30m 3 / h / person, the ventilation frequency of south-facing and east-facing rooms is 4-6 times / hour, and the ventilation frequency of north-facing rooms is 3-5 times / hour. Taking into account the two factors of ventilation frequency and minimum fresh air volume, the larger value of the two is selected as the basis for selection; at the same time, the proportion of indoor ventilation devices is also adjusted according to the air exchange volume.
[0016] Furthermore, the outdoor air exchange closing cover is arranged on the top of the ventilation pipe, one end of which is hinged to the ventilation pipe and a counterweight is provided on the outer end, and the side opposite to the hinged end is connected to the steel wire.
[0017] The front (outer) of the indoor ventilation cover has a counterweight. Due to gravity, the cover closes against the oblique indoor ventilation duct opening. When the controller is turned, the wire rope pulls the cover open. The user controls the rotation of the cover by moving the lever up and down, thereby controlling whether the room needs ventilation.
[0018] The outdoor ventilation cover is connected to the ventilation duct via a pulley and features a counterweight at the rear. Due to gravity, the counterweight becomes heavier than the cover itself, keeping it open. A steel cable connects the other end of the cover to the outdoor ventilation control via the pulley. The user controls the opening and closing of the cover by turning the control. The outdoor ventilation water guide has a hole reserved for the metal sleeve of the control, and structural adhesive is applied to the contact surface to prevent rainwater from entering.
[0019] In summary, the present invention installs ventilation ducts on the exterior of a building, connecting them to each room. Each duct is equipped with an independent air closure control device, allowing each room to control whether or not to exchange air with the outside air, depending on user needs. This device can increase the number of indoor air exchangers, ensuring efficient air circulation in all rooms requiring ventilation. When used in conjunction with window ventilation or open windows, the convection effect is even better. BRIEF DESCRIPTION OF THE DRAWINGS
