What is the ventilation of the whole house?
The system of ventilation of the whole house is a system designed to remove musty air from the house and bring fresh air from outside the house ventilation. Many builders and homeowners decided to build firmly sealed houses without "leaks" that would allow air in and out. Sealing the house firmly to prevent air from entering or leaving, is often preferred to heat and cold houses: no house owner does not want air conditioning or heat to escape the gaps near windows or walls. However, the strictly enclosed house can cause problems with the quality of the inner air (IAQ). Toxins, pollutants, bacteria and odors are not able to escape from home and fresh outdoor air is unable to enter. As a result, the air inside the sealed house becomes outdated and in some cases unhealthy. The ventilation system of the whole house is used to ensure that the house is firmly sealed and without suggestions, while still providing correct circulation so that fresh air can enter the house and outdated air canera.
According to the American society for heating, cooling and air conditioning engineering (Ashrae), the air in the house should change 0.35 times per hour, or should enter the house for each person present. Kitchen and bathrooms are recommended to have an even higher air turn, up to 100 changes per minute, often achieved by using the exhaust fan. These "changes" require that outdoor air to enter the room, either through a window, door, fan, window air conditioning or the entire ventilation system.
house owners who want to ensure the right ventilation of the whole house have the possibility to use a mechanical ventilation system. The mechanical ventilation systems are designed to push the air out of the rooms and bring new air.M, which accurately calculates the needs of the ventilation of each room in the house based on the settings adapted to the installation program. Some mechanical ventilation systems even have a heat recovery device built in this preliminary heatingOutdoor air when entering the house in winter.
Thus, the entire house ventilation system provides a balance between energy efficiency and air quality in the inner air. Home owners can keep a home without suggestions and not tax their heating and cooling system with unwelcome outdoor air. The ventilation system can allow them to still achieve sufficient air turnover to maintain its home without bacteria and odor.
