Residential ventilators can be divided into many types according to their working principles and application scenarios. It is particularly important to 

choose a suitable solution based on actual needs and building conditions.

1. Mechanical ventilation equipment

‌Intelligent fresh air system‌

‌One-way flow system‌: Ventilation is carried out through the principle of negative pressure, with low cost but limited ventilation efficiency

‌Two-way flow system‌: Two-way ventilation design, significantly improved ventilation efficiency, suitable for highly airtight residential buildings

‌Full heat exchange system‌: Recover exhaust heat, reduce energy loss, and have outstanding energy-saving effects, but the pipeline system needs to be 

pre-installed, and the initial investment is relatively high

‌

Multi-function exhaust fan‌

Applicable to local areas such as kitchens and bathrooms, divided into duct type and window type. The duct type needs to be connected to the exhaust d

uct, and the window type is easy to install, but the filter needs to be cleaned regularly to avoid blockage

Economical and practical, can quickly deal with problems such as oil smoke and moisture, but the overall air circulation improvement is limited

‌

Industrial strong fan‌

Assists in accelerating the flow of indoor and outdoor air, needs to be used in conjunction with the door and window opening strategy, and is suitable for

 temporary enhanced ventilation needs

2. Natural ventilation equipment

‌Unpowered ventilator (turbine ventilator)‌

Uses natural wind pressure and thermal pressure difference to achieve ventilation, does not require electric drive, and is suitable for roof installation

Features include zero noise, maintenance-free, and blade design optimizes typhoon resistance and ventilation efficiency

‌

Ventilation Venetian blinds ‌

Combining ventilation and privacy protection, the airflow direction is guided by adjustable blade angles, and is suitable for bedrooms, living rooms and other areas

‌

3. Selection and use suggestions

‌Parameter matching‌: Pay attention to parameters such as air volume, total pressure, and noise to ensure that the fan characteristics match the pipe network resistance

‌Scene adaptation‌: It is recommended to install a high-power exhaust fan in the kitchen, and the bedroom can be combined with a fresh air system or blinds to achieve continuous ventilation

‌Maintenance points‌: Clean the filter and fan blades regularly; in cold areas, prevent snow and ice from accumulating at the exhaust vents

Through a comprehensive mechanical and natural ventilation solution, residential air quality problems can be effectively solved while balancing energy consumption and costs
