Description

Technical Field

[0001] This utility model relates to the field of indoor air conditioning technology, specifically to an indoor air environment conditioning and control device. Background Technology

[0002] Deteriorating indoor air quality is caused by a combination of factors, including the release of pollutants, poor ventilation, and environmental imbalance. The core purpose of regulation is to eliminate health threats, restore comfort, and meet specific functional needs. Modern buildings are often designed with airtight structures for thermal insulation, such as double-glazed windows and sealed doors and windows. If windows are not opened for extended periods, such as in winter when people are afraid of the cold or on smoggy days, indoor pollutants cannot be expelled in time, leading to a continuous increase in concentration. The harm can range from short-term discomfort to long-term illness.

[0003] Existing indoor air conditioning methods mostly involve installing a total heat exchange core between the air intake and exhaust paths for ventilation. However, the cross-sectional area of ​​the heat exchange core is fixed and cannot dynamically adapt to the environment and needs. For example, when the temperature difference is small, the air resistance is large, and the fan needs to maintain high power operation, which increases energy consumption. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are: The heat exchange core of this invention can dynamically adapt to the environment through the deformation of flexible material.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-7 This utility model provides a technical solution: an indoor air environment conditioning and control device, including a housing 1, a heat exchange core 2 inside the housing 1, a first air supply base 15 and a second air exhaust base 18 on one side of the housing 1, a second air supply base 16 and a first air exhaust base 17 on the other side of the housing 1, the heat exchange core 2 including a base frame 21, a top frame 22, a core 23 and an electric cylinder 25, one end of the core 23 is fixedly connected to the base frame 21, the other end of the core 23 is fixedly connected to the top frame 22, the cylinder body of the electric cylinder 25 is fixedly connected to the base frame 21, the push rod of the electric cylinder 25 is fixedly connected to the top frame 22, and an elastic element 24 is provided at the top of the top frame 22.

[0020] The flexible membrane is the heat exchange medium layer of the heat exchange core 2, mainly responsible for heat and moisture transfer. Through the deformation of the flexible material, it dynamically adapts to the environment. The base frame 21 of the heat exchange core 2 is fixed, while its top frame 22 can move under the drive of the electric cylinder 25. When the electric cylinder 25 drives the top frame 22 to move upward, the top frame 22 drives one end of the core 23 to move upward synchronously, realizing expansion, increasing the flow channel cross-sectional area, reducing wind resistance, reducing fan power consumption, and saving energy and reducing resistance. Conversely, when the electric cylinder 25 drives the top frame 22 to move downward, the top frame 22 drives one end of the core 23 to move downward synchronously, realizing compression, decreasing the flow channel cross-sectional area, increasing airflow speed, and enhancing heat exchange. When the temperature difference is large, the electric cylinder 25 drives the flexible membrane to reduce the flow channel cross-sectional area. At this time, the airflow speed increases, enhancing the heat and moisture exchange efficiency. When the temperature difference is small, the electric cylinder 25 drives the flexible membrane to expand the flow channel cross-sectional area. At this time, the airflow resistance decreases, saving energy and reducing fan power consumption. The heat exchange core 2 can dynamically adapt to the environment and needs, and automatically adjust the heat exchange efficiency according to the indoor and outdoor temperature difference.

[0021] The top of the housing 1 is fixedly provided with a cover plate 3, the top of the elastic element 24 is fixedly connected to the cover plate 3, and the bottom of the elastic element 24 is fixedly connected to the top frame 22.

[0022] The elastic element 24 is made of elastic material and can deform accordingly with the deformation of the heat exchange core 2, ensuring that the upper part of the heat exchange core 2 and the cover plate 3 always remain sealed and restricting the flow direction of airflow.

[0023] The inner wall of the box 1 is fixedly provided with a first partition 11, a second partition 12, a third partition 13 and a fourth partition 14.

[0024] like Figure 6 and Figure 7 As shown, the air supply channel and the air exhaust channel are separated by the first partition 11, the second partition 12, the third partition 13 and the fourth partition 14.

[0025] The first partition 11, the second partition 12 and the fourth partition 14 are all provided with grooves, and opening and closing plates 111 are installed in the grooves. The opening and closing plates 111 are rotatably connected to the grooves by a rotating shaft.

[0026] The opening and closing plate 111 is driven by the motor 112, and the output shaft of the motor 112 is fixedly connected to the opening and closing plate 111.

[0027] When the motor 112 is working, it drives the opening and closing plate 111 at one end to rotate relative to the partition. When the opening and closing plate 111 rotates and opens, the slot on the partition opens, and the airflow can preferentially pass through the slot on the partition. When supplying air, the opening and closing plates 111 on the first partition 11 and the second partition 12 open, and the supply airflow bypasses the heat exchange core 2 and is sent into the room. When exhausting air, the opening and closing plates 111 on the first partition 11 and the fourth partition 14 open, and the exhaust airflow bypasses the heat exchange core 2 and is discharged to the outside.

[0028] The opening and closing plate 111 is used as a bypass valve to bypass the heat exchange core 2 under certain working conditions, allowing the airflow to be sent directly into the room or discharged to the outside without passing through the heat exchange core 2, reducing wind resistance and energy consumption caused by heat exchange. The fan does not need to overcome the pressure loss of the core 23, avoiding energy waste caused by ineffective heat exchange.

[0029] The first air supply base 15 has a built-in air supply filter 151 installed at the fresh air inlet to intercept suspended particulate matter, hair, insects and other pollutants in the outdoor air. The high-efficiency filter can also remove bacteria, viruses or gaseous pollutants, directly improve the indoor breathing environment, purify the fresh air and send clean fresh air into the room.

[0030] The second air supply base 16 has a built-in air supply fan 161. The air supply fan 161 purifies the outdoor fresh air through the air supply filter 151 and recovers energy through the heat exchange core 2, and then pressurizes and sends it into the room to replenish fresh air.

[0031] The first exhaust base 17 has an exhaust filter 171 built into it. It is located at the inlet of the exhaust duct and is mainly used to filter particulate matter in the indoor exhaust air, protecting the subsequent heat exchange core 2, exhaust fan 181 and the stability of system operation.

[0032] The second exhaust base 18 has an exhaust fan 181 built in it. The exhaust fan 181 draws in the indoor polluted air, releases energy through the heat exchange core 2, and then discharges it to the outside.

[0033] Among them, a lifting plate 31 is welded and fixed on the cover plate 3. The lifting plate 31 has a slot for lifting and fixing the whole device.

[0034] Working principle: When supplying air, such as Figure 6 As shown, the air supply fan 161 purifies the outdoor fresh air through the air supply filter 151 and recovers energy through the heat exchange core 2, then pressurizes and supplies it into the room to replenish fresh air. During exhaust, as... Figure 7 As shown, the exhaust fan 181 draws in stale indoor air, purifies it through the exhaust filter 171, and after the heat exchange core 2 releases energy, it is exhausted outdoors. Energy is indirectly transferred through the heat exchange core 2, preventing the mixing of two airflows. In winter, when the indoor exhaust air passes through the core 23, heat is transferred to the fresh air on the other side, preheating the fresh air before it enters the room, reducing heating energy consumption. In summer, when the indoor exhaust air passes through the core 23, cold air is transferred to the fresh air on the other side, precooling the fresh air before it enters the room, reducing cooling energy consumption. The heat exchange core 2 can... By dynamically adapting to the environment through the deformation of flexible materials, when the temperature difference is large, the electric cylinder 25 drives the flexible membrane to reduce the cross-sectional area of ​​the flow channel. At this time, the airflow speed increases and the heat and moisture exchange efficiency is enhanced. When the temperature difference is small, the electric cylinder 25 drives the flexible membrane to expand the cross-sectional area of ​​the flow channel. At this time, the airflow resistance is reduced, energy-saving operation is achieved, and the power consumption of the fan decreases. The opening and closing plate 111 is used as a bypass valve to bypass the heat exchange core 2 under specific working conditions, allowing the airflow to be sent directly into the room or discharged to the outside without passing through the heat exchange core 2, thereby reducing wind resistance and energy consumption caused by heat exchange.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
