The fresh air system of a mobile soundproof room is designed to provide a controlled flow of outside air into the room while maintaining sound isolation and acoustic performance. This system ensures that occupants have a comfortable and healthy environment inside the soundproof room without compromising its soundproofing capabilities. The working principle involves several components and considerations:

Air Intake and Filtration: Fresh air is typically drawn from the outside environment through an intake vent or grille. This intake is equipped with filters that help remove airborne particles, dust, and contaminants from the incoming air.


Silencing and Attenuation: To maintain sound isolation, the incoming air is directed through a series of acoustic baffles, silencers, or insulated ducts. These components help attenuate the sound of the incoming air, preventing external noise from entering the soundproof room.


Air Mixing and Distribution: The fresh air is mixed with the room's interior air to maintain a comfortable temperature and humidity level. This mixing can occur through a ventilation system that combines the incoming air with the room's existing air supply.

HVAC System Integration: The fresh air system is often integrated with a heating, ventilation, and air conditioning (HVAC) system. The HVAC system helps regulate the temperature and humidity inside the room, ensuring a comfortable environment for occupants.


Airflow Control and Regulation: The airflow rate is controlled to ensure an adequate supply of fresh air while preventing excessive drafts or discomfort. Dampers, fans, and variable air volume (VAV) controls are often used to regulate the airflow based on the room's occupancy and requirements.


Pressure Differential and Sound Isolation: Maintaining a proper pressure balance between the interior and exterior of the room is important for sound isolation. The fresh air system is designed to prevent air leakage that could compromise the soundproofing of the room.


Energy Efficiency: The fresh air system may incorporate energy-efficient technologies, such as heat recovery ventilation (HRV) or energy recovery ventilation (ERV). These systems transfer heat or energy from the outgoing air to the incoming fresh air, reducing energy consumption.


Air Quality and Occupant Health: The primary purpose of the fresh air system is to provide occupants with clean and fresh outdoor air, improving indoor air quality and supporting occupant health and well-being.


Noise Control: In addition to controlling the sound of the incoming air, the fresh air system itself should be designed to minimize noise generated by fans, motors, and airflow. Proper acoustic insulation and vibration isolation techniques may be employed to achieve this.


User-Friendly Controls: The fresh air system is typically equipped with user-friendly controls that allow occupants to adjust ventilation settings, airflow rates, and temperature to suit their preferences.

In summary, the working principle of the fresh air system in a mobile soundproof room involves filtering, silencing, and attenuating incoming air while ensuring proper ventilation, temperature control, and energy efficiency. The system aims to provide a comfortable and healthy environment inside the soundproof room while maintaining its sound isolation capabilities.
