I. Introduction of heat exchange mode of fresh air system

Fresh air system is a kind of ventilation equipment commonly used in modern buildings, which can effectively send outdoor fresh air into the room after constant temperature, while discharging indoor dirty air outside. The heat exchange mode is the full heat exchanger of the fresh air system, which realizes the heat exchange of indoor and outdoor air through the heat exchanger, thereby reducing the loss of energy and achieving the effect of energy saving and environmental protection.

Second, the working principle of the heat exchange mode of the fresh air system
The heat exchange mode of the fresh air system is mainly realized through the heat exchanger. When the fresh air and the discharged dirty air meet in the heat exchanger, through a special structure and process, the two parts of the air achieve temperature exchange in the heat exchange process, rather than simply mixing. In this way, the fresh air sent into the room can maintain a temperature close to the room temperature, reducing the energy loss caused by temperature differences.

Third, the advantages of fresh air system heat exchange mode

1. Energy saving and environmental protection: Through the heat exchange mode, the fresh air system can effectively reduce the loss of energy, to achieve the effect of energy saving and environmental protection. This not only reduces the building's energy consumption, but also helps protect the environment.
2. Improve comfort: the air sent into the room by the fresh air system after heat exchange, the temperature is similar to the room, making the indoor air more comfortable and pleasant.
3. Extend the life of the equipment: due to the reduction of energy loss, the operation of the equipment of the fresh air system is more stable, thus extending the life of the equipment.
Application scenario of heat exchange mode of fresh air system
The heat exchange mode of the fresh air system is suitable for all kinds of buildings, especially where air conditioning or heating needs to be turned on for a long time. For example, office buildings, hospitals, schools, shopping malls and other buildings can use the heat exchange mode of fresh air systems to improve indoor air quality and reduce energy consumption.

Five, how to choose and install fresh air system

1. Choose the right fresh air system: Choose the right fresh air system according to the area of the building, the use of demand and other factors. At the same time, ensure that the fresh air system has a heat exchange function.
2. Reasonable arrangement of tuyere: The tuyere arrangement of the fresh air system should be reasonable to ensure that the air can be evenly distributed to each room.
3. Regular maintenance: The fresh air system needs regular maintenance during use to ensure its normal operation and extend its service life.
Six, the use of fresh air system heat exchange mode precautions
1. Regularly check the heat exchanger: The heat exchanger is the core component of the heat exchange mode of the fresh air system, and its working status needs to be checked regularly to ensure its normal operation.
2. Reasonable setting of temperature differences: When setting the temperature difference of the fresh air system, it is necessary to take into account the difference between indoor and outdoor temperatures and the comfort of the human body to avoid discomfort caused by excessive temperature differences.
3. Combined with other energy-saving measures: Although the heat exchange mode of the fresh air system has energy-saving effects, it is still necessary to combine other energy-saving measures (such as reasonable building insulation, energy-saving lamps, etc.) to further improve the energy-saving effect.
In short, the heat exchange mode of the fresh air system is an effective energy saving and environmental protection measure, which can help us improve indoor air quality and improve the comfort of the living and working environment. When selecting and installing fresh air systems, we need to make reasonable selection and arrangement according to actual needs and conditions, and pay attention to regular maintenance and precautions during use.
