Why are building negative pressure systems more suitable for residential use?
Release time:
2021-05-08
Building system negative pressure refers to the continuous removal of indoor polluted air to the outside by a silent fan, creating negative pressure inside. According to the principle of atmospheric equilibrium, fresh outdoor air is directly introduced into the room through wall-mounted or window-mounted air inlets, keeping the indoor air fresh and clean.
Building system negative pressure refers to the continuous expulsion of indoor polluted air to the outside by a silent fan, creating negative pressure inside. According to the principle of atmospheric balance, outdoor fresh air is directly introduced into the room through wall-mounted or window-mounted inlets, making the indoor air fresh and clean. The building system negative pressure host is installed on the ceiling of the bathroom or kitchen, sucking in the indoor polluted air into the host and forcefully expelling it from the room, naturally forming a negative pressure zone in the room. Utilizing the negative pressure effect, outdoor fresh air is filtered through ventilation outlets and automatically enters the room, forming an uninterrupted, continuous intake and exhaust cycle.
Characteristics of Building System Negative Pressure:1During system operation, the indoor air in kitchens and bathrooms, etc., is first expelled outside. Fresh air is then introduced from bedrooms and living rooms, where fresh air is most needed, creating convection within the room and achieving good ventilation.2The piping of the building system negative pressure system is only needed in kitchens and bathrooms, and the main unit can be installed on the ceiling of the bathroom or kitchen, saving space.3The building system negative pressure host is environmentally friendly, energy-saving, and electricity-saving.4Sound insulation and noise reduction, uniform and stable ventilation, good effect.
Functions of Building System Negative Pressure:1Continuously provides fresh indoor air necessary for the human body, benefiting human health and children's growth and development.2Allows every household to enjoy fresh air without opening windows, avoiding the dust and noise brought by opening windows.3Fresh air entering the room through the air inlets of each room pushes the polluted air in the room out evenly from the air outlets of the kitchen or bathroom. Therefore, the exhaust air in each room is relatively independent, and there will be no cross-contamination of airflow.4The air volume meets the standards, and each room does not need a pipe network, making installation and maintenance convenient. It also has the advantages of high reliability, low noise, and low power consumption, and can effectively prevent "air conditioning disease" and colds.5Reduces or eliminates kitchen and bathroom odors and harmful gases slowly released for a long time after indoor decoration.6Reduces or eliminates mildew on indoor walls, furniture, and clothing caused by long-term poor ventilation.
Building system negative pressure is suitable for residential buildings, small offices, hospital wards, hotel rooms, etc. Working principle: Indoor polluted air is discharged from areas such as bathrooms and kitchens; fresh air enters through cracks in the walls. Building system negative pressure is widely used due to its simple structure, easy installation, few pipelines, and low cost. Building system negative pressure is a"forced exhaust natural intake" ventilation system. It only installs a fan in the exhaust system and uses the negative pressure principle to drive indoor air flow. Fresh air enters the living space, and polluted air is discharged from the bathroom. According to the living area and population, the fresh air volume is set according to national ventilation standards.
