Abstract:
A distributed ventilation system and control method for a ward. The system comprises a distributed air supply system and a distributed exhaust system. The distributed air supply system comprises an air supply power module (6), an air supply pipe, a bed head air supply outlet (7), and a bed tail air supply outlet (8). The distributed exhaust system comprises an exhaust power module (9) and a vertical exhaust pipe (10). The lower part of the vertical exhaust pipe (10) is provided with a lower exhaust outlet (11), the middle is provided with an upper exhaust outlet (12), and the upper part is provided with an exhaust connector (13). The lower exhaust outlet (11) and the upper exhaust outlet (12) are located on the front surface of the vertical exhaust pipe (10), and the exhaust connector (13) is located on the back surface of the vertical exhaust pipe (10). According to the system and control method thereof, fresh air can be separately fed into a patient activity area and a visiting and accompanying personnel activity area to meet sanitary fresh air requirements of various personnel, and airflow is controlled not to cross, thereby reducing the probability of nosocomial cross infection. Because a modular exhaust structure can be quickly installed and be quickly connected into exhaust equipment, the installation is easy and quick, the cost is low, and the odor in a toilet can be fully and effectively discharged.
