What are the causes and hazards of negative pressure?
With the development and progress of the times, modern residences are vastly different from traditional ones, especially the airtightness of doors and windows. With the development of technology, their airtightness and sound insulation are constantly improving, becoming increasingly tight. Most households are equipped with range hoods and bathroom exhaust fans. When using the above equipment, due to the good sealing of the room, negative pressure will be generated, and the imbalance of indoor and outdoor air pressure will cause sewer odors to back up, and doors and windows may deform and become difficult to open under negative pressure. Long-term negative pressure can harm the human body, causing tinnitus, palpitations, and memory loss, especially for the elderly and children. Intermittent negative pressure is particularly harmful to health.
Qianjia pressure ventilation system thoroughly solves the problem of indoor negative pressure, making people's homes warmer and more comfortable. The system automatically senses negative pressure, requires no manual operation, and can automatically balance the internal and external pressure difference. It has two modes: winter and summer. In winter, it automatically tests the temperature of the incoming air and heats and filters it if there is a temperature difference. It is sensitive (20Pa), quiet, energy-efficient, and features full computer intelligent management, using high-quality materials and modern technology.
