What does the ventilation duct of the house mean?

The air duct of a house, also known as vent or ventilation duct, refers to an important channel for providing air exchange for the house and keeping the indoor air fresh. It mainly plays the role of guiding fresh air into the room and eliminating dirty air, and ensures that the humidity and quality of indoor air meet the requirements of human health. The quality of indoor air duct directly affects the indoor air quality, and has obvious influence on health.

Building air ducts are mainly divided into three types: natural ventilation, forced ventilation and heat recovery. Natural ventilation refers to the exchange of indoor and outdoor air through the natural influence of outdoor weather; Forced exhaust is realized by using mechanical ventilation equipment; Heat recovery is to exchange heat between indoor and outdoor air through heat exchanger, thus reducing air temperature difference and energy consumption. Different airway types have their own advantages in different occasions and applications.

The maintenance of the air duct of a house is an important link that cannot be ignored in life. Cleaning the ventilation openings of houses regularly can effectively prevent and reduce bacteria, mold, dust mites and other particles from entering the room, and play a role in keeping the indoor environment clean and hygienic. At the same time, reasonable air ducts can make full use of indoor and outdoor natural environment, save energy and reduce labor costs, which is beneficial to environmental protection. Therefore, regular inspection and maintenance of airway health and normality can improve the quality of living environment and protect people's health and happiness.
