Designing a Good Ventilation System
How Ventilation Systems Keep Your Home Healthier
In reality, most indoor air quality is poorer than that of outdoor air. Allergens like dust, pollen, and dander build up inside your home and become bothersome, especially to those with asthma and allergies. Ventilation systems help reduce the amount of irritants in your home, including pollutants, bacteria, and odors.
Ventilation systems help reduce condensation indoors by regulating temperature and lowering humidity. When condensation goes unchecked in your home it causes mold and mildew, and possibly damages walls and structural supports.
By keeping moisture under control, ventilation systems eliminate the breeding grounds for dust mites. These irritating pests contribute to eczema and breathing issues, and reducing their ability to reproduce keeps your home a safer place.
Linked to lung cancer, radon gas is a byproduct of uranium decaying inside rocks and soil. A good ventilation system can lower the amount of radon gas inside your home.
When air pressure inside is lower than air pressure outside, it’s called negative pressure. This situation can suction outdoor air into your home. This creates a dangerous problem when gases like carbon monoxide from heating systems get pulled inside through the chimney or appliance vents.
Ventilate Home/Office or Public Gathering places ( Best)
Exhaust-only mechanical ventilation. This is a relatively common strategy. Small exhaust fans, usually in bathrooms, operate either continuously or intermittently to exhaust stale air and moisture generated in those rooms.
Supply-only mechanical ventilation. As the name implies, a fan brings in fresh air, and stale air escapes through cracks and air-leakage sites in the house. The air supply may be delivered to one location, dispersed through ducts, or supplied to the ducted distribution system of a forced-air heating system for dispersal.
Balanced ventilation. Much better ventilation is provided through a balanced system with air purification in which separate fans drive both inlet and exhaust airflow. This allows us to control where the fresh air comes from, where that fresh air is delivered, and from where exhaust air is drawn. Balanced ventilation systems can be either point-source or ducted. Ask air conditioning installation services like this AC installation in Germantown, TN to know the ventilation of your unit.
Balanced ventilation with heat recovery. If there are separate fans to introduce fresh air and exhaust indoor air, it makes a lot of sense to locate these fans together and include an air-to-air heat exchanger so that the outgoing house air will precondition the incoming outdoor air.
