Get RESIDENTIAL MECHANICAL VENTILATION - Rocky View

Ventilation systems can be categorized as one of four types: exhaust, supply, balanced, and heat-recovery. The right ventilation system for a particular house depends upon the climate and the needs of the structure.

There are four purposes of ventilation: Provide a continuous supply of fresh outside air. Maintain temperature and humidity at comfortable levels. Reduce potential fire or explosion hazards.

Mechanical ventilation systems circulate fresh air using ducts and fans, rather than relying on airflow through small holes or cracks in a home's walls, roof, or windows. Homeowners can breathe easier knowing their home has good ventilation. Better Indoor Air Quality.

a. Natural ventilation can occur through air infiltration from doors, windows or cracks and it lacks a controlled, mechanical process that ensures that a building is properly ventilated. Whereas, mechanical ventilation allows you to control the airflow and ensure that a space receives the needed amount of ventilation.

There are three methods that may be used to ventilate a building: natural, mechanical and hybrid (mixed-mode) ventilation.

Mechanical ventilation systems will provide the best and most reliable air filtration and cleaning. ... This type of ventilation is most effective in hot or mixed-temperature climates. Exhaust ventilation: Indoor air is constantly sent outdoors, reducing the amount of contaminants in your commercial spaces.

There are three types of whole-house mechanical ventilation systems: exhaust-only, supply-only, and balanced. Each system uses a combination of fans, ducting, dampers and controls, and they each have different pros, cons, and costs accompanying them.

Exhaust-only ventilation. This ventilation type uses a fan to move indoor air out of your home, while outdoor air is drawn in through leaks. ... Supply-only ventilation. ... Balanced ventilation.

Exhaust ventilation systems work by depressurizing your home. The system exhausts air from the house while make-up air infiltrates through leaks in the building shell and through intentional, passive vents. Exhaust ventilation systems are most appropriate for cold climates.

The two main types of mechanical ventilation include positive pressure ventilation where air (or another gas mix) is pushed into the lungs through the airways, and negative pressure ventilation where air is usually, in essence, sucked into the lungs by stimulating movement of the chest.
