Description

Technical Field

[0001] This utility model relates to the technical field of gas-fired fresh air function units, and in particular to a gas-fired fresh air function unit. Background Technology

[0002] With the rapid pace of urbanization and residents' increasing pursuit of quality of life, buildings are becoming increasingly airtight, leading to a significant decline in indoor air quality. Living in such an environment for extended periods can easily cause health problems such as dizziness, fatigue, and difficulty breathing. Therefore, gas-fired fresh air handling units are widely used in various types of buildings to regulate air and improve indoor air quality.

[0003] Currently, most industrial gas-fired fresh air units on the market are roof-mounted, but the burners and gas pipelines are installed indoors, resulting in the direct emission of exhaust smoke into the room. Long-term operation will pollute the indoor air, especially in winter when the room is sealed and insulated. The combustion of gas consumes oxygen and the oxygen in the space cannot be effectively replenished, affecting people's activities. At the same time, installing gas units indoors requires improved fire protection measures, increases the overall cost, and the introduction of fresh air through air ducts increases wind resistance and energy consumption. The fresh air volume cannot be adjusted, which presents a series of problems.

[0004] Therefore, those skilled in the art have provided a gas-fired fresh air unit to solve the problems mentioned in the background art. Utility Model Content

When in use, the unit is installed on a pre-drilled base on the roof, allowing the air outlet to extend into the room. This ensures safe combustion of the burner outdoors, preventing the consumption of indoor oxygen, and completely venting exhaust gases outdoors, thus avoiding indoor air pollution. Furthermore, since all gas connections are located outdoors, it does not increase the indoor fire safety burden. Its integrated system design effectively reduces fresh air intake resistance and energy consumption. By controlling the switching baffle with a switching actuator, the fresh air intake can be flexibly adjusted according to different operating conditions to optimize indoor air quality and improve system operating efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A gas-fired fresh air unit includes a fresh air hood, a return air hood, and a roof.

Its integrated system design effectively reduces the resistance to fresh air intake and energy consumption. By switching the actuator to control the switching baffle, the fresh air intake can be flexibly adjusted according to different operating conditions to optimize indoor air quality and improve system operating efficiency.

[0009] Furthermore, a support frame is fixedly connected to one edge of the return air hood, and a lifting rod is fixedly connected to both sides of the two end faces of the support frame. A lifting hole is opened on one side of each of the multiple lifting rods.

[0010] The above technical solutions, including the design of the lifting rods and lifting holes, facilitate the lifting and installation of the equipment, ensure a more stable and safer installation process, and improve the overall structural reliability of the equipment.

[0011] Furthermore, switching baffles are provided on both sides of the return air hood's end face;

[0012] Through the above technical solutions, the switching baffle can flexibly adjust the airflow direction and flow rate, achieve more efficient air conditioning and flow control, improve the adaptability and operating efficiency of the equipment, and meet the needs of different working environments.

[0013] Furthermore, the support frame is installed on the upper part of the roof, and one side of the air outlet extends into the room;

[0014] By installing the support frame on the roof, the space occupied by the above technical solution can be reduced, and the air outlet can be extended into the room to better deliver the treated fresh air into the room, effectively improving air circulation and environmental comfort.

[0015] Furthermore, the interlayer between the fresh air hood and the return air hood serves as a fresh air inlet;

[0016] Through the above technical solutions, the design of the fresh air inlet can ensure that fresh air is smoothly introduced into the system, providing sufficient fresh air for the room, while avoiding the direct impact of outside air on the indoor environment and improving air quality.

[0017] Furthermore, the outer edge of the return air hood near the support frame is the indoor return air inlet;

[0030] Working Principle: When in use, the unit is first fixed to a base with an opening in the roof (16), allowing the air outlet (13) to extend into the room through this opening. The burner is located outdoors for combustion, thus avoiding the consumption of indoor oxygen and ensuring that exhaust smoke is directly discharged outdoors without polluting indoor air. Simultaneously, since the gas connections are all located outdoors, they do not impose additional burden on normal fire safety measures in the indoor space. The unit adopts an integrated system design, combining fresh air with indoor return air, reducing resistance to fresh air intake and lowering energy consumption. The switching actuator (2), installed inside the fresh air hood (17) and outside the return air hood (18), controls the switching baffle (14) to adjust the fresh air supply according to different operating conditions. When the equipment is installed on the roof 16, the support frame 15 surrounds the equipment to ensure that the equipment is stably installed in the pre-set opening in the roof. The air outlet 13 extends into the room through the opening in the roof 16. The combustion chamber 7 is connected to the gas pipe and the heat exchange pipe 4. The high-temperature hot air generated by the combustion of the gas introduced by the gas pipe inlet 3 with the air is transferred to the heat exchange pipe 4 and discharged through the connected exhaust pipe 8. The fresh air inlet 10 serves as the entry point for outdoor air, and the indoor return air outlet 11 serves as the entry point for indoor air. The fan 5 adjusts the guide vanes 12 through the actuator under system control and sends the heated fresh air or indoor air out through the air outlet 13 to achieve heating and circulation of indoor air.
