Compressed air type fresh air system capable of exhausting air by doors

Abstract

The invention relates to a compressed air type fresh air system capable of exhausting air by doors. The compressed air type fresh air system is applied to a room group. The room group comprises a plurality of rooms and a public space communicated with the multiple rooms, the fresh air system comprises an exhaust module, and the exhaust module is arranged on the public space or the outer walls of the rooms; and the doors of the rooms are provided with air doors capable of being communicated the interiors of the rooms with the public space outside the rooms, and when the fresh air system operates, an air flow channel for being communicated the public space with the interiors of the rooms is formed by opening the air doors, and an air exhaust module communicated with the air flow channel exhausts dirty air replaced by fresh air into the ambient atmosphere. The air doors are arranged on the doors of the rooms, the exhaust module is arranged on the public space or the outer walls of the rooms, a dirty air exhaust channel among the rooms, the public space and the environment is opened, the compressed air type fresh air system is transformed into air supply and exhaust two-way flow from air supply pipe one-way flow, so that the good effects of dirty air exhaust and fresh air supply are achieved, and the air quality inside a building is fundamentally improved.

Description

technical field [0001] The invention relates to the technical field of fresh air systems, in particular to a pressurized air type fresh air system adopting house door exhaust air. Background technique [0002] In buildings, especially residences, due to the need to set up different family functional spaces such as living room, bedroom, study, kitchen, bathroom, storage room, etc., the original large-scale building space with good ventilation and lighting conditions is divided into many parts by internal walls and doors and windows. Smaller unit space. These walls and doors and windows cut off the air flow and light connection between each unit space, and the ventilation and lighting conditions of each unit space become worse. At the same time, in buildings, especially residences, due to the breathing and excretion of humans and animals, the diffusion of gas and oil fumes during cooking, the escaping of water vapor during bathing and cleaning, and the volatilization of benze...

Problems solved by technology

[0007] At present, the building positive pressure fresh air system widely implemented in the real estate industry actually relies on the leakage of walls, doors and windows or random opening of doors and windows to realize the discharge of dirty air and the introduction of fresh air. The premise is wrong. , will inevitably lead to invalid results
