Not all kitchen ventilation is equal from ductwork to ductless system to lower ventilation system.
If you are updating your kitchen, you may want to know if you need a range hood.
Most residential building codes do not require a range hood on or above the stove, but you'd better make sure your place is no exception. Even if there is no legal requirement, you should think twice before giving up the hood completely.
The range hood is used to collect grease, moisture and cooking smell in the air, but not all range hoods are the same. The following is a brief overview of the kitchen ventilation system that you need to consider:
Ventilated or ducted hood
If you do too much, you may want a hood that leads to the outdoors. The duct cover actually discharges the polluted air to the outside, eliminating various forms of air pollution caused by cooking. Fresh air is sucked in from the outside to keep the kitchen air clean and prevent cooking smell and even grease particles from spreading to the whole room-especially your kitchen cabinets.
If your stove and hood are along the exterior wall, the pipes are the simplest; Conduits can pass through the house wall from the rear of the hood. For the range placed against the inner wall, the pipe can go up between the soffit or ceiling joists above the cabinet and then extend through the nearest outer wall. No matter where the pipeline runs, it is important that the pipeline extend all the way to the outside. Ventilation ducts should not terminate in attics or other enclosed spaces.
Unlike the ducted range hood, the ducted range hood exhausts air outdoors. The ductless range hood consists of a fan and a charcoal filter, which can absorb grease particles, odors and smoke. Air is filtered through charcoal and then recycled to the kitchen. The hood filter needs to be cleaned or replaced regularly.
Ductless hoods are not as effective as duct hoods in purifying air, but they are easier to install and usually cheaper.
Pull down system
The pull-down system is usually part of this series; They are usually located on the roof near the burner. This is not a particularly effective ventilation system. Cooking forums are full of complaints about fans taking heat away from the food being prepared.
Another style of pull-down system is pop-up. This vent remains flush with the cooking surface until you need it; Press the button and the vent will rise 8 to 10 inches above the cooking surface. Is the cooking ready? Press a button and it disappears again.
Both types of pull-down ventilators use fans to draw air through filters into ductwork, which runs under the floor or above cabinets, usually outdoors. Their camouflage quality makes pull-down vents ideal for kitchen islands and peninsulas. Pop-up pull-down ventilation system is more effective than embedded ventilation system, but both are not as effective as upper suction ventilation system (range hood) in removing cooking pollutants.
