Exhaust fans are simple, electrically operated fans used to get rid of odors, heat and moisture from kitchens and bathrooms.
They are typically mounted in the wall or ceiling.
Kitchens also will have an exhaust fan within a range hood over stoves and ovens.
There are many reasons for residential ventilation, here are the three main types of exhaust systems: Kitchen Exhaust Fans: In estimating the requirements for ventilating a kitchen, it's customary to allow a complete change of air every single 2 minutes.
In many situations, it is also desirable to have all the extracted air leave via hoods or canopies located over ranges, steam tables, dishwashers and comparable sources of localized heat and contaminants.
Allowing for a total alter of air each two minutes only applies to average conditions and the modifications from this average should be produced on the basis of the kitchen size and also the type of heat and vapor producing equipment.
Exhaust hoods are typically placed over the majority of the heating kitchen appliances.
They need to be placed directly over the heat and vaper-producing equipment approximately 80 inches from the floor to enable head clearance.
If a supply system is needed, the amount of exhaust air should be greater than the volume of supply air to prevent undesired odors and moisture spreading to other rooms of the residence.
The supply air is usually figured on the basis of 75% of the exhaust air.
Bathroom Exhaust Fans: An air change each and every three minutes can be a desirable for bathroom ventilation.
Systems of this sort should be entirely diverse and separated from other ventilation systems.
Bathrooms situated on the inside of a structure require ducts to exhaust air to the outside.
Compact fans are especially recommended for use in bathroom exhaust systems.
Their compact style requires a minimum of space and they're capable of operating against the resistance of the technique.
Whole-House Ventilation: Whole-house ventilation can be a ventilating method in which a significant centrally situated fan supplies natural air-conditioning.
In a dry climate that experiences hot days and very cool nights, whole-house ventilation fans often supply a suitable replacement for air conditioning.
Cooler air is drawn in by way of the windows from the lower level of the house at night and is forced by means of the attic vents.
This method produces a steady supply of filtered, fresh air to all of the living spaces of the house.
It is most effective when the outdoor temperature is below 85 degrees.
Whole-house ventilators demand quite small maintenance.
If the unit is equipped having a filter, it will need to be periodically cleaned or replaced.
Inspect the fan blades from time to time and clean them when there's a noticeable buildup of dirt, dust or grease.
They are typically mounted in the wall or ceiling.
