Description

Energy-saving window sill embedded air ventilator

technical field

The invention relates to an energy-saving windowsill embedded air ventilator.

Background technique

The importance of air to human survival and development is self-evident, and it is an indispensable resource for human beings. Clean air, healthy breathing, staying away from various respiratory diseases, and advocating a healthy life are also everyone's pursuit. According to statistics, the average person spends more than 50% of their time at home every day, while indoor air pollution is 2-3 times more serious than outdoor, and more than 60% of diseases are related to indoor air pollution.

The fresh air ventilator is a kind of indoor air purification equipment, which is designed and developed according to the principle of supplying air on one side of the airtight room and inducing air on the other side, and then forming a "fresh air flow field" indoors. It relies on mechanical air supply and induced air to force the formation of a fresh air flow field in the system to provide fresh filtered outdoor air for the room. With enough fresh air, people can breathe high-quality, fresh air indoors. Clean air, which is rich in fresh oxygen and does not contain harmful smog and dust particles, is beneficial to human health.

At present, there are certain problems in the application of fresh air ventilators in the field of indoor air purification equipment, especially in civil buildings, that is, in the field of air purification with high requirements for small household spaces. Since the fresh air ventilator is a large-scale ventilating device with a heat recovery device, and relies on mechanical air supply and induced air to force the formation of a fresh air flow field in the system, it is necessary to configure a larger power fan for it, and For relatively large or long air ducts, two larger openings should be dug on the building wall, and it is best to separate them in terms of spatial distance. A number of air treatment contents also make the volume of the fresh air ventilator further increase. These factors all increase the air volume, static pressure loss, outlet total pressure, input power, effective ventilation rate, exchange efficiency, and noise of the fresh air ventilator. Control difficulty of main control parameters such as control. In some cold areas of our country, when the outdoor fresh air temperature is about -10°C, frost may appear on the exhaust side, and an air preheater needs to be installed in front of the fresh air ventilator. Regarding the calculation method of fresh air volume, my country's national standard GB/T18883 provides average method and regression equation method. 30 cubic meters per hour, if calculated as a family of 3, the fresh air volume needs to reach nearly 100 cubic meters per hour. In this way, in order to ensure the ventilation effect and heat recovery efficiency, the fresh air ventilator can only maintain a relatively large body. At present, it is still impossible to make the volume small and easy to install. Although these factors can be ignored in the industrial application environment, but for civilian use For large-scale buildings and office buildings, its application is subject to many restrictions. At present, fresh air ventilators can only be installed in the ceiling compartment of indoor buildings. On the one hand, due to the constraints of the installation environment, they cannot be made larger to better meet the application requirements. On the other hand, the equipment that meets the application requirements is due to Restricted by the installation environment of the building, it has to be reduced in the design of the scheme, thus losing some application effects. Its installation damages indoor buildings, especially the interior decoration. Moreover, the relatively complicated structure of the fresh air ventilator has a relatively high manufacturing cost and is expensive, which also makes it very slow to be popularized in the civilian field.

It can be seen that there has been an urgent demand for an indoor air purification device that is simple in structure, effective in air purification, easy to install, excellent in cost performance, and suitable for popularization and application.

In this embodiment, the liquid crystal display 7 is set on the host 6 .

Mounting seat 1 is shown in accompanying drawing 1, and its preferred size is length 280mm, width 200mm, height 50mm, thickness is 2mm, and material is stainless steel. An expansion screw hole 2 and a wire hole 5 are provided on the mounting base 1 , and a first sliding rail 3 is provided on the inner wall of the mounting base 1 . The mounting base 1 and the host 6 are respectively provided with locking devices 4 which define the relative positions of the two. The length of the mounting base 1 can be selected according to the thickness of the wall, generally 60mm longer than the thickness of the wall. The part looks nicer. Before installation, it is necessary to open a rectangular wall hole under the window frame (if it is a building with a pre-reserved installation position, there is no need to dig the wall), and the size of the hole on the wall should be as close as possible to the installation seat 1 size, so that the subsequent edge modification is more beautiful and cost-effective. After the mounting base 1 is put in place, use expansion screws to fix it through the expansion screw holes 5 provided on the mounting base 1 . Then through the wire hole 2, the indoor power line is inserted into a quick plug in the concealed wire in the wall or the external open wire, and this plug will be connected with the power system on the chassis main body 6 to provide power supply for the equipment of the present invention.

As shown in accompanying drawing 2, the host computer 6 of the present invention is provided with the second slide rail 17, through the sliding fit of the second slide rail 17 and the first slide rail 3, the host computer 6 is loaded into the mounting base 1, and through locking The device 4 is connected and positioned.

For the outdoors, the exhaust air outlet 24 is located above the fresh air inlet 20, and indoors, the exhaust air inlet 23 is located above the fresh air outlet 21, all following the principle that the fresh air is on the bottom and the dirty air is on the top. Its ingenious cooperation fully It conforms to the principle of the flow of fresh air and dirty air in the air where the fresh air is below and the stale air is rising continuously. A wire hole 31 corresponding to the position of the wire hole 2 of the mounting seat 1 is also opened on the main frame 6 to realize wiring.

As shown in accompanying drawing 3, the first centrifugal fan 9 is positioned at the downstream of the fresh air filter screen 8 on the gas flow direction in the fresh air passage 19, realizes the effect of drawing wind in the fresh air passage 19, and the second centrifugal fan 10 is in the exhaust passage. The gas flow direction in 22 is located at the downstream of the exhaust filter screen 12 to realize the exhaust effect in the exhaust channel 22 . The first heat exchanger 11 has a first air inlet 29 communicated with the exhaust air outlet 24 and a first air outlet 27 communicated with the fresh air inlet 20, and the second heat exchanger 13 has a first air outlet 27 communicated with the exhaust air inlet 23. Two air outlets 30 and the second air inlet 30 that communicate with the fresh air outlet 21, the two ends of the fresh air passage 19 are connected with the first air outlet 27 and the second air inlet 30 respectively, and the two ends of the exhaust passage 22 are connected with the second air inlet respectively. The second air outlet 30 is connected with the first air inlet 29 .

The introduction process of outdoor fresh air is shown as the hollow arrow in accompanying drawing 3, and outdoor fresh air is fresh air through first heat exchanger 11 by fresh air inlet 20 and is introduced from outdoor to indoor, and first centrifugal fan 9 provides induced-air pressure, and fresh air When passing through the first heat exchanger 11, it absorbs the heat left by the indoor exhaust air brought by the heat exchanger 11, advances along the fresh air passage 19, and passes through the fresh air filter screen 8 (generally, a medium-efficiency filter screen is used, has reached the effective filtration and purification requirements for outdoor fresh air), filters out impurities in the air, and enters the room through the second heat exchanger 13, at this time, the fresh air flow absorbs the indoor air brought by the second heat exchanger 13 again The heat left by the air is exhausted, and then enters the room from the fresh air outlet 21 of the second heat exchanger 13 . That is to say, when the outdoor fresh air enters the room through the device of the present invention, it has become clean, and the temperature is close to the indoor temperature, which means that considerable electric energy is saved for the air conditioner. If a full-heat heat exchanger is used, the humidity of the fresh air can be further adjusted to make the indoor air more comfortable.

The discharge process of indoor air is shown by the solid arrow in Figure 3. The indoor dirty air enters the exhaust air inlet 23 of the second heat exchanger 13 from the indoor. At this time, the second centrifugal fan 10 provides exhaust pressure, and the indoor dirty air passes through the second The second heat exchanger 13 leaves the residual heat of the indoor air on it, and then passes through the exhaust filter screen 12 (it can be used for primary effect or nylon dense mesh, mainly to ensure that foreign objects such as small flying insects in the outdoors are removed when the equipment is turned off. Reverse into the room) continue to travel along the exhaust channel 22 to the first heat exchanger 11, after the indoor dirty air passes through the first heat exchanger 11, it is discharged to the outside through the exhaust outlet 24, and the waste heat is further retained in heat exchanger 11. From this, we have clearly seen that the device of the present invention organically combines the two processes of fresh air ventilation and waste heat recovery, and its operating principle is simple and effective. Indoor temperature can save considerable air-conditioning energy consumption, which is especially meaningful in summer and winter or when we don't want to open windows. The power of the first centrifugal fan 9 and the second centrifugal fan 10 is 19W, and a 220V AC power supply is used. The centrifugal fan is the main power-consuming part of the equipment of the present invention. Therefore, the power consumption of the equipment of the present invention is extremely small, and it is less than 0.15 kilowatt-hours of electricity per day based on 3 air changes per day and 3 hours of operation. In addition, through the heat recovery of the heat exchanger in the device of the present invention, the 30% electric energy saved for the indoor air conditioner, the actual power consumption can be basically ignored.

As shown in Figure 4, we can see that the fresh air filter screen 8 and the exhaust air filter screen 12 effectively control the cross-section of the entire air channel in their respective air channels. The first centrifugal fan 9 and the second centrifugal fan 10 are in the middle position in the respective air passages, and provide wind pressure traction force for the respective air passages. In this embodiment, the fresh air filter adopts a medium-efficiency filter to filter and purify the outdoor fresh air; the exhaust air filter adopts a special 600-mesh nylon dense mesh to minimize exhaust air resistance and prevent outdoor foreign objects from entering in reverse.

As shown in accompanying drawing 5, the structure of the first heat exchanger 11 and the second heat exchanger 13 are the same, it is a kind of convective air heat exchanger, the preferred size is that the width is 200mm, the height is 50mm, has two intersecting The air flow channel, and it is a heat exchanger with reinforced wave-shaped air guide groove heat exchange plate, it has a large heat exchange area, strong pressure resistance, high heat transfer efficiency, compact structure, light and firm, and easy installation , long service life, strong versatility of components, wide range of materials for plates and many other advantages and characteristics.

The above-mentioned heat exchanger with reinforced wave-shaped air guide groove heat exchange plates includes a plurality of heat exchange plates 25 stacked up and down, and a flat rectangular air channel is formed between two adjacent heat exchange plates 25 . As shown in Figure 6, the surface of the heat exchange plate 25 has a plurality of air guide heat exchange grooves 26 arranged densely in sequence and arranged in a wave shape in the longitudinal direction, and the two heat exchange plates 25 adjacent up and down rotate 90 degree stacking.

As shown in accompanying drawing 7, the energy-saving window sill embedded air ventilator also includes the air outlet device 14 that is connected on the exhaust air outlet 24, and the air outlet device 14 has the outdoor air outlet 15 toward the outside, and the air outlet device 14 The bottom surface is inclined from bottom to top from the outdoor air outlet 15 to the exhaust outlet 24, and the inclination angle α is 3°-10°, preferably 6°. In this embodiment, the size of the air outlet device 14 is 200 mm in width and 100 mm in length. The outdoor air outlet 15 has an inclination toward the exhaust outlet 24 from top to bottom.

After all the installation and wiring are completed, the air outlet device 14 needs to be installed on the exhaust outlet 24 of the first heat exchanger 11 . The other end opposite to the end where the outdoor air outlet 15 of the air outlet device 14 is located is the riveted flange edge 16 of the air outlet. The riveted flange edge 16 is riveted with the exhaust outlet 24 of the first heat exchanger 11, and after installation, the outdoor air outlet 15 of the air outlet device 14 is in the outward direction.
