Technical Field

[0001] This utility model relates to the field of ventilation equipment technology, specifically to a high-efficiency and energy-saving ventilation equipment for fresh air heat exchange. Background Technology

[0002] Ventilation equipment is basically a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Ventilation fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings for ventilation, dust removal and cooling. Most of them are energy-saving and environmentally friendly ventilation equipment, which have excellent ventilation and air exchange functions and are widely used in some scenarios.

[0003] Chinese Patent No. CN221629930U discloses an energy-saving, safe, and environmentally friendly ventilation device, including a ventilation duct, an installation groove, and an installation plate. The top of the ventilation duct has an installation groove that communicates with the inside of the ventilation duct. The top two ends of the installation groove have slots. The inner walls of the slots are slidably connected to locking blocks by locking springs. By using a plug-in and locking method with a plug-in plate, slots, locking blocks, a fixed locking plate, and a movable locking plate, the dustproof net is installed and locked. When removing or installing the dustproof net, simply press the push plate to move the movable locking plate to the other side of the locking block, and then press the spring to release the locking, which greatly improves the convenience of removing and placing the dustproof net.

[0004] The aforementioned ventilation equipment has the following drawbacks in practical use: First, it can only achieve a single air exchange function and does not have a heat exchange function, nor can it enable energy exchange between indoor and outdoor air, making its function relatively limited; second, during ventilation, it lowers the indoor temperature and cannot effectively maintain a constant indoor temperature, reducing its practicality; finally, although the equipment is equipped with a dust filter, which provides some dust protection, it cannot guarantee effective feedback on air purification, resulting in air entering the room without a filtering and purification effect, further reducing its practicality.

[0025] 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.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a high-efficiency and energy-saving ventilation device for fresh air heat exchange, including a housing 1. The housing 1 is equipped with a filter mechanism 10 and an electric auxiliary heating mechanism 13. A heat exchanger 2 is set in the middle. The heat exchanger 2 has an exchange core inside, and aluminum sheets 3 are set around it and extend into the interior for air exchange. The housing 1 is equipped with a partition 4 for limiting the heat exchanger 2. One end of the partition 4 is fixed to the inner side wall of the housing 1, and the other end is equipped with a Y-shaped limiting plate 5. The Y-shaped limiting plate 5 is installed to limit the edge of the heat exchanger 2. Multiple sets of partitions 4 and Y-shaped limiting plates 5 are symmetrically arranged in the housing 1, dividing the internal cavity of the housing 1 into four parts. The heat exchanger 2 is rhomboid in shape.

[0027] As a preferred embodiment, the heat exchanger 2 is an existing device. When the product is operating, indoor exhaust air and fresh air flow through the heat exchanger core in a cross-flow manner. The heat exchanger facilitates energy exchange between indoor and outdoor air, thereby achieving ventilation and energy saving. Specifically, when indoor air passes through the heat exchanger, it exchanges heat, cold, and humidity with outdoor air, transferring heat, cold, and humidity from the indoor air to the outdoor air while absorbing heat, cold, and humidity from the outdoor air. In this way, energy loss is minimized during the indoor-outdoor air exchange process, thus achieving energy saving.

[0028] The combination of the partition 4 and the Y-shaped limiting plate 5 not only divides the internal cavity of the housing 1 into four cavities, but also effectively limits the heat exchanger through the Y-shaped limiting plate 5, ensuring stability and high efficiency.

[0029] Specifically, the side wall of the housing 1 is provided with a fresh air inlet 6, a fresh air outlet 7, a stale air inlet 8, and a stale air outlet 9, and each of the above air outlets corresponds to one of the four cavities inside the housing 1. The fresh air inlet 6 and the stale air outlet 9 are located on one side of the housing 1, and the fresh air outlet 7 and the stale air inlet 8 are located on the other side of the housing 1.

[0030] Specifically, a filter mechanism 10 is provided on one side of the fresh air inlet 6. The filter mechanism 10 is located inside the housing 1 and installed in the frame 11, forming a pull-out structure. Correspondingly, a detachable side plate 12 is provided on the outside of the housing 1.

[0031] Specifically, the filtration mechanism 10 consists of a pre-filter plate 101, an activated carbon filter plate 102, and a HEPA high-efficiency filter plate 103.

[0032] As a preferred option, by removing the side panel 12, the internal filter mechanism 10 can be taken out for cleaning and replacement, ensuring that the performance of the filter mechanism 10 remains stable. It is equipped with a pre-filter, activated carbon filter and HEPA high-efficiency filter, which can effectively filter the air at the fresh air inlet 6, purify the indoor and outdoor air, and improve the indoor air quality.

[0033] Specifically, an electric auxiliary heating mechanism 13 is provided on one side of the filter mechanism 10. The electric auxiliary heating mechanism 13 is fixedly installed inside the housing 1 and located between the filter mechanism 10 and the heat exchanger 2. The electric auxiliary heating mechanism 13 is electrically connected to the fully automatic digital display intelligent temperature controller 14, which is fixedly installed on the outer wall of the housing 1.

[0034] As a preferred option, the electric auxiliary heating mechanism 13 is an existing device. During winter use, the electric auxiliary heating mechanism 13 can be turned on to reheat the outdoor cold fresh air before sending it into the room, thereby more effectively ensuring the indoor temperature. It plays a role in heating while exchanging fresh air. In addition, the electric auxiliary heating mechanism 13 is equipped with a fully automatic digital display intelligent temperature controller 14, which can set the start and stop temperatures according to its own needs. When the temperature is reached, the electric auxiliary heating will automatically turn off and stop heating; when the temperature is low, the electric auxiliary heating will automatically start and heat up. When air circulates through the fresh air inlet, the outdoor cold fresh air is reheated and sent into the room, thereby more effectively ensuring the indoor temperature. It plays a role in heating while exchanging fresh air. During the process of indoor and outdoor air exchange, it can maintain the humidity, coolness and temperature of the indoor air, thus providing a more comfortable indoor environment.

[0035] Specifically, a filter mechanism 2 15 is provided on one side of the sewage inlet 8. The installation method of filter mechanism 2 15 is the same as that of filter mechanism 10. Filter mechanism 2 15 is composed of a primary filter plate. In this embodiment, the working principle and installation structure of filter mechanism 2 15 are the same as those of filter mechanism 10. The difference is that filter mechanism 2 15 is composed only of a primary filter plate and is used for filtering sewage.

[0036] Specifically, exhaust fan units 16 are installed inside both the fresh air outlet 7 and the waste air outlet 9, and are located inside the casing 1. The exhaust fan units 16 are used as power to carry out air circulation and exchange functions.

[0037] Specifically, a dustproof component 17 is fixedly installed on the outside of the fresh air inlet 6 and the waste air outlet 9. The dustproof component 17 can block some objects in the air and prevent them from entering the air vent. A duct installation component 18 is installed on the outside of the fresh air outlet 7 and the waste air inlet 8. An electrical control box 19 is installed in the middle of the fresh air outlet 7 and the waste air inlet 8. The electrical control box 19 is fixedly installed on the outer wall of the casing 1 and is electrically connected to the exhaust fan unit 16.

[0038] Specifically, a cover plate 21 is fixedly installed on the top of the casing 1 by screws 20. The cover plate 21 is removable, which allows for easy replacement or repair of internal parts.

[0039] In practical implementation, this utility model involves installing the equipment in various locations requiring ventilation, such as livestock farming, workshops, greenhouses, and drying rooms. It is particularly useful in places with high indoor air quality requirements, as well as in locations needing constant temperature and humidity, where the heat exchange fresh air unit provides a more stable environment. Outdoor fresh air enters the equipment through fresh air inlet 6, undergoes high-efficiency filtration through filter mechanism 10, purifying the air before entering the heat exchanger 3. Meanwhile, indoor stale air enters the equipment through stale air inlet 8, is filtered through filter mechanism 15, and enters the heat exchanger 3. As the air flows through the heat exchanger core in a cross-flow manner, the heat exchanger facilitates energy exchange between indoor and outdoor air, achieving energy recovery and utilization, thus saving energy. Simultaneously, it treats polluted indoor air through heat exchange before expelling it outdoors. In winter, the electric auxiliary heating function can be activated to reheat the fresh air before it is introduced into the room.

[0040] 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.
