Description

Technical Field

[0001] The utility model relates to the technical field of building ventilation, and in particular to a green energy-saving fresh air system for temperate areas which has the advantages of simple structure, energy saving and consumption reduction, and adjustable temperature and wind speed. Background Art

[0002] Ordinary classrooms in primary and secondary schools must meet the requirement that full windows should not be exposed to sunlight for less than 2 hours on the winter solstice. Therefore, most teaching buildings adopt the solution of opening large areas of external windows to solve the problem of sunlight and lighting. In temperate regions, most classrooms are not equipped with air conditioners, but solve the indoor ventilation problem by utilizing natural ventilation through external windows. However, due to the orientation and large areas of windows in many classrooms, the solar heat radiation in summer increases the indoor temperature. In addition, considering the safety of students, the actual openable window area of ​​many classrooms is small, resulting in slow indoor air flow. Not only is the interior of the classroom relatively stuffy, but also CO2, odor and other gases and suspended particulate matter exceed the standard, making the indoor thermal environment and comfort poor, seriously affecting the normal learning of students, and poor air flow can easily increase the chance of cross infection between students.

[0003] In the prior art, in order to solve the problem of poor indoor air flow in the above-mentioned mild areas, a fresh air system with forced ventilation, filtration and even heating is generally added. However, since the existing fresh air system is a small but complete independent system set up in each classroom, the maintenance workload is large and the air volume is mostly only 300m 3 About, and the fresh air volume of primary school classroom is 19m 3 / h. The standard requirements of people are quite different. Although there are also large-volume fans selected to increase the air volume, the high wind pressure and noise will increase the impact on teaching. There are also multiple low-noise fresh air systems to increase the air volume and reduce noise, but not only the cost is high and the maintenance workload is large, but it also takes up more indoor space. For this reason, there is also a technical solution of using a central fresh air system and laying pipes to each classroom to solve the problems of the existing independent fresh air systems in each classroom, but due to the high investment cost of the central fresh air system and pipelines, it is also necessary to renovate the classrooms and even the teaching buildings, which makes the construction period longer, and the later use and maintenance costs are high. Especially for the vast number of rural schools, it is not only difficult to promote, but also often idle due to the pressure of use costs after promotion. In addition, some teaching buildings cannot be laid due to structural reasons. Central fresh air systems and pipelines.

[0004] Therefore, for teaching and office buildings in temperate areas, where mechanical ventilation and air conditioning are not installed or a fresh air system is installed but is not in good condition, there are currently no good structural measures to solve the problems of sunlight, ventilation and indoor thermal environment comfort for such rooms. Therefore, it is particularly important to study a fresh air system with simple structure, energy saving and consumption reduction, and adjustable temperature and wind speed. Utility Model Content

[0025] like Figure 1 and 2 As shown, the utility model comprises a building room 1, wherein the building room 1 is provided with an external lighting glass window 2 on one side of the outer wall, and the building room 1 is provided with an inner walkway 3 or an outer corridor on the outer side of the wall on the other side away from the glass window 2;

[0026] An air passage 5 extending along the inner corridor 3 or the outer corridor is arranged at the lower part of the wall of the building room 1 on the side close to the inner corridor 3 or the outer corridor, and air vents connecting the inside and outside of the building room 1 are arranged on both sides of the air passage 5. At least one side of the air passage 5 is provided with an adjustable shutter 6, and a high window 7 connecting the inside and outside of the building room 1 is arranged at the upper part of the wall where the air passage 5 is located.

[0027] The air duct 5 is arranged inside the wall of the building room 1 on the side of the inner corridor 3 or the outer corridor, or is arranged inside the inner corridor 3 or the outer corridor and is attached to the lower part of the aforementioned wall. The air duct 5 is arranged inside the wall to save the structure from occupying the building space, and does not damage the appearance of the building, and the air duct 5 is not easily damaged by external forces; and the air duct 5 is arranged inside the inner corridor 3 or the outer corridor and is attached to the lower part of the aforementioned wall to reduce the damage to the wall, and the wall only needs to open a hole to communicate with the air duct 5, and the engineering workload is also small.

[0028] The air passage 5 of the building room 1 is provided with at least one air inlet and at least two air outlets at intervals along the extension direction of the inner corridor 3 or the outer corridor, the air inlet is connected to the inner corridor 3 or the outer corridor, and the air outlet is connected to the building room 1; at least two high windows 7 are provided on the upper part of the wall of the building room 1. Fewer air inlets can reduce the number of air intake fans and filters added later, and it is also convenient to take measures to prevent mosquitoes and rodents; while more air outlets can not only increase the uniformity of indoor air distribution, but also reduce the wind speed of the air outlet, realize the full-section through-replacement of the building room 1, and achieve a basically windless feeling.

[0029] The air inlet of the air channel 5 at the lower part of the wall of the building room 1 close to the inner corridor 3 or the outer corridor and the upper high window 7 are staggered along the extension direction of the inner corridor 3 or the outer corridor. The staggered arrangement of the air inlet and the high window 7 can increase the return air distance in the inner corridor 3 or the outer corridor, and can effectively improve the efficiency of fresh air replacement, so that the indoor air can be significantly changed with a small amount of fresh air.

[0030] The air inlet of the air channel 5 is provided with a fixed louver 8, and the adjustable louver 6 is provided on the air outlet of the air channel 5.

[0034] At least one end of the inner corridor 3 is provided with a fresh air blower and / or a heating device.

[0035] The working principle and working process of the utility model are as follows:

[0036] like Figure 1 and 2 As shown,

[0037] 1. The air in the area near the glass window 2 of the building room 1 is exposed to outdoor sunlight 14 (external thermal environment), and the air temperature rises, causing the air volume to expand and flow toward the upper space.

[0038] 2. The hot air 13 in the upper part of the room flows into the inner corridor 3 or the outer corridor (external cold environment) through the high window 7 on the upper part of the wall of the inner corridor or the outer corridor. The air contacts the cold environment, causing the temperature to drop, resulting in a reduction in volume and flowing downward. If necessary, the outlet fan 11 is started to force the hot air 13 in the upper part of the room to enter the inner corridor 3 or the outer corridor through the high window 7 at an accelerated speed.

[0039] 3. The cold air 12 from the inner aisle 3 or the lower part of the outer corridor enters the air channel 5 through the fixed louvers 8. If necessary, the air inlet fan 9 is started to force the cold air 12 from the inner aisle 3 or the lower part of the outer corridor to enter the air channel 5 at an accelerated speed. At the same time, the filter 10 filters out most of the suspended matter in the air.

[0040] 4. Adjust the opening of the adjustable louver 6 as needed, so that the cold air 12 in the air duct 5 enters the lower space of the building room 1 through the adjustable louver 6.

[0041] 5. The lower cold air 12 in the building room 1 is irradiated by the sunlight 14 through the glass outer window 2, and the temperature rises again, causing the volume to expand and flow to the upper space, so that the indoor air forms a natural circulation flow using the thermal pressure difference.

[0042] Through the above technical measures, the air flow in the building room 1 is accelerated, the temperature inside the building room 1 is reduced in summer, the indoor thermal environment and air quality are improved, and the comfort level is improved. In addition, the whole process does not require energy consumption, and the indoor air temperature and wind speed are adjustable.
