Description

Technical Field

[0001] This utility model relates to the field of building ventilation equipment technology, specifically an energy-saving ventilation device for indoor air circulation in building design. Background Technology

[0002] As people's requirements for indoor environmental quality continue to increase, the importance of building indoor ventilation is becoming increasingly prominent. Good ventilation can effectively improve indoor air quality, reduce the concentration of harmful gases, reduce the growth of germs, and provide people with a comfortable and healthy living and working environment. However, traditional ventilation devices often have problems such as high energy consumption and low ventilation efficiency, which are difficult to meet the needs of sustainable development in the current energy-scarce environment.

[0003] Conventional building indoor air ventilation devices lack a recycling function, resulting in high energy consumption and low ventilation efficiency. Furthermore, if the air inlet filter cannot be replaced, prolonged continuous use may cause blockage of the air inlet, reducing air intake efficiency and preventing air filtration. Therefore, there is a need for an energy-saving ventilation device for building indoor air circulation that can ensure ventilation efficiency while saving energy and has a replaceable filter. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an energy-saving ventilation device for indoor air circulation in building design. It has the advantages of ensuring ventilation efficiency while saving energy and allowing for filter replacement. It solves the problems of general indoor air ventilation devices in building design lacking a recycling function, resulting in high energy consumption and low ventilation efficiency. Furthermore, if the filter at the air inlet cannot be replaced, it may cause blockage of the air inlet after long-term continuous use, which not only reduces the air intake efficiency but also fails to filter the air.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving ventilation device for indoor air circulation in building design, comprising a device housing, wherein a bidirectional flow fresh air fan and a heat exchanger are respectively arranged inside the device housing, the air inlet of the bidirectional flow fresh air fan is fixedly connected to a first air duct inlet pipe and a second air duct inlet pipe, the air outlet of the bidirectional flow fresh air fan is fixedly connected to a first air duct outlet pipe and a second air duct outlet pipe, the bidirectional flow fresh air fan is fixedly connected to the interior of the heat exchanger through the first air duct inlet pipe and the second air duct outlet pipe, and an exhaust pipe and an air inlet pipe are fixedly connected to the front surface of the heat exchanger.

[0008] Preferably, the device housing has an internal mounting plate, a handle is fixedly mounted on the top of the mounting plate, a connecting block is fixedly connected to the bottom of the mounting plate, a limit block is fixedly connected inside the device housing, the bottom of the connecting block is adapted to the inside of the limit block, a filter screen is fixedly connected inside the connecting block, and sealing rings are fixedly connected to both sides of the filter screen.

[0009] Preferably, a shock absorber is fixedly installed inside the housing of the device, and the opposite sides of the shock absorber are fixedly connected to the outer surface of the bidirectional flow fresh air fan. The multiple shock absorbers installed inside the housing of the device can effectively reduce the vibration during the operation of the fan, allowing it to operate more stably, thereby ensuring the ventilation efficiency of the device.

[0010] Preferably, flared joints are fixedly connected to the outer surfaces of the second air duct inlet pipe, the first air duct outlet pipe, the exhaust pipe, and the inlet pipe. Flared joints are installed on the second air duct inlet pipe, the first air duct outlet pipe, the exhaust pipe, and the inlet pipe to improve ventilation efficiency.

[0011] Preferably, a partition is fixedly connected inside the device housing, and a partition frame is fixedly connected to the outer surface of the partition.

[0012] Compared with the prior art, this utility model provides an energy-saving ventilation device for indoor air circulation in building design, which has the following beneficial effects:

[0013] 1. Traditional building design indoor air ventilation devices have high energy consumption and low ventilation efficiency, and the air inlet filter cannot be replaced, which not only reduces the intake efficiency but also fails to filter the air. The design of this utility model uses two independent air ducts of a bidirectional flow fresh air fan. One duct sends fresh outdoor air into the room, and the other exhausts indoor stale air to the outside. Two fans inside drive these two air ducts respectively, so that fresh air and stale air flow in their respective channels, realizing bidirectional flow and efficient exchange of indoor and outdoor air. In this process, heat exchangers are used to exchange heat and reduce energy loss. This utility model inserts the connecting block into the device shell from above until it is locked into the limiting block. At this time, the sealing rings on both sides are in contact with the air intake pipe, allowing the filter screen to filter out larger particles of dust and impurities in the air.

[0014] 2. This ventilation device integrates energy saving without affecting ventilation efficiency and allows for replacement of the inlet filter. By installing several shock absorbers between the bidirectional flow fresh air fan and the device casing, the device can effectively reduce vibration during fan operation, allowing it to operate more stably and thus ensuring the ventilation efficiency of the device. By setting partition frames on the partitions at both ends of the device casing, the device can effectively prevent air circulation short circuits, airflow turbulence, and interference between fresh and polluted air.

[0019] 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.

[0020] Example 1:

[0021] Referring to Figures 1-3, an energy-saving ventilation device for indoor air circulation in building design includes a housing 1. Inside the housing 1, a bidirectional flow fresh air unit 2 and a heat exchanger 3 are respectively installed. The air inlets of the bidirectional flow fresh air unit 2 are fixedly connected to a first air duct inlet pipe 4 and a second air duct inlet pipe 6. The air outlets of the bidirectional flow fresh air unit 2 are fixedly connected to a first air duct outlet pipe 7 and a second air duct outlet pipe 5. The bidirectional flow fresh air unit 2 is fixedly connected to the interior of the heat exchanger 3 through the first air duct inlet pipe 4 and the second air duct outlet pipe 5. The heat exchanger 3 is fixedly connected to an exhaust pipe 8 and an intake pipe 9. A shock absorber 16 is fixedly installed inside the housing 1. The opposite sides of the shock absorber 16 are fixedly connected to the outer surface of the bidirectional flow fresh air fan 2. Flared joints 17 are fixedly connected to the outer surfaces of the second air duct intake pipe 6, the first air duct outlet pipe 7, the exhaust pipe 8, and the intake pipe 9. A partition 18 is fixedly connected inside the housing 1. A partition frame 19 is fixedly connected to the outer surface of the partition 18.

[0022] Working Principle: First, install the outer casing 1 of the device in a suitable location according to the building's interior layout. After installation, start the bidirectional flow fresh air unit 2. The bidirectional flow fresh air unit 2 has two independent air ducts. One duct introduces fresh outdoor air into the room through the intake pipe 9, the first air duct intake pipe 4, and the first air duct outlet pipe 7. The other duct exhausts stale indoor air to the outside through the exhaust pipe 8, the second air duct intake pipe 6, and the second air duct outlet pipe 5. Two internal fans drive these two air ducts respectively, allowing fresh air and stale air to flow in their respective channels, achieving bidirectional flow and efficient exchange of indoor and outdoor air. Heat exchange is also involved in this process. Heat exchanger 3 reduces energy loss through heat exchange. When the outdoor air temperature is low, heat exchanger 3 can absorb the heat from the indoor exhaust air and preheat the introduced outdoor air, reducing the loss of indoor heat. When the outdoor air temperature is high, heat exchanger 3 can transfer the cold air from the indoor exhaust air to the introduced outdoor air, lowering its temperature and thus reducing the load on the indoor air conditioning system, achieving energy saving. Shock absorber 16 can play a shock absorption role when the bidirectional flow fresh air unit 2 is running. The partition 18 and the partition frame 19 on it can effectively prevent air circulation short circuits, airflow turbulence, and interference between fresh and polluted air.

[0023] Example 2:

[0024] Referring to Figures 1-3, the device housing 1 has an internal mounting plate 10. A handle 11 is fixedly mounted on the top of the mounting plate 10, and a connecting block 12 is fixedly connected to the bottom of the mounting plate 10. A limit block 13 is fixedly connected inside the device housing 1. The bottom of the connecting block 12 is adapted to the inside of the limit block 13. A filter screen 14 is fixedly connected inside the connecting block 12, and sealing rings 15 are fixedly connected to both sides of the filter screen 14.

[0025] Working principle: After running for a period of time, use the handle 11 to pull the mounting plate 10 and the connecting block 12 upwards to clean or replace the filter screen 14. After that, insert the connecting block 12 from the top of the device housing 1 until it is locked into the limit block 13. At this time, the sealing rings 15 on both sides are in contact with the air intake pipe 9, allowing the filter screen 14 to filter out larger particles of dust, impurities, etc. in the air.
