When discussing the functions, characteristics, and applications of fresh air total heat exchangers, we can conduct a detailed analysis from the following aspects:

###1、 Function and application of fresh air total heat exchanger

1. * * Air temperature regulation * *: By regulating the outdoor air temperature through pipelines to approach the indoor air temperature, it can continuously provide high-performance and high-efficiency ventilation.

2. * * Air quality improvement * *: Drive air circulation indoors to create a constant humidity space, filter out outdoor air dust and other pollutants through equipment, and supplement fresh indoor air.

3. * * Energy saving and Environmental Protection * *: The fresh air system adopts an independent air air total heat fresh air ventilator for energy-saving operation of air intake and exhaust heat exchange, responding to the requirements of energy saving and environmental protection.

4. Strong adaptability: The scope of use has expanded from industrial special occasions to general civilian occasions at room temperature, adapting to changes in market demand.

5. * * Improve indoor air quality * *: Prevent the spread and cross infection of viruses and bacteria, and address the challenge of improving building airtightness.

6. * * Coping with urban air pollution * *: Providing effective solutions to the problem of high levels of suspended particulate matter in urban air.

###2、 Characteristics of fresh air total heat exchanger

1. * * Heat exchange efficiency improvement * *: From initial dehumidification to reheat recovery, and then to total heat recovery, heat exchange efficiency continues to improve.

2. Diversified heat transfer methods: shifting from absorption or adsorption to the use of permeable working methods to meet the needs of different scenarios.

3. * * Optimization of heat transfer materials * *: From using materials with complex structures, special materials, and high prices, to using inexpensive materials that can ensure heat transfer efficiency.

4. * * Rich Types * *: The types of air air fresh air ventilators available on the market are divided into two categories: static and rotary, depending on whether the heat exchange core is moving or not, to meet the needs of different users.

###3、 Advantages and disadvantages of static and rotary heat exchangers

1. * * Static heat exchanger * *: The advantages are no cross contamination, no movement of the heat exchange core, continuous and reliable heat exchange process, dust removal, control of indoor air pressure, isolation of outdoor noise, and maintenance of indoor thermal environment comfort.

2. * * Rotary heat exchanger * *: The advantage is that the transfer of heat and humidity is completed in the same channel, and the thermal resistance and humidity resistance of the heat transfer medium are small. Even when the temperature and humidity differences of the medium are very small, it can still work effectively. The disadvantage is that some materials have a high desorption temperature, and there is a possibility of cross contamination between the two gases.

In summary, the fresh air total heat exchanger has been widely used in industrial special occasions and general civilian occasions at room temperature due to its efficient air temperature regulation, air quality improvement, energy-saving and environmental protection characteristics, as well as continuously improving heat transfer efficiency and diversified heat transfer methods. Static and rotary heat exchangers each have their own advantages and disadvantages, and users can choose the appropriate type according to their specific needs. With the advancement of technology and the expansion of the market, the application prospects of fresh air total heat exchangers will be even broader.
