Ventilation design options for kitchens include decorative wood hoods with stainless steel liners, chimney-style hoods that incorporate ventilation into a decorative design element, and downdraft ventilation that can be built into a cooktop or range. These systems can improve air quality, health, and energy efficiency. In February 2022, Tim H. discussed the essentials required to design an effective Kitchen Ventilation System (KVS), which includes the hood and the exhaust fan.
Extractor fans are mounted on walls and ceilings in rooms with high moisture levels, and should be installed in bathrooms, kitchens, and bathrooms. Choose a range hood that fits your kitchen layout and has enough airflow to remove heat, odors, smoke, and oils from your range top. Whole-house ventilation involves using one or more fans and duct systems to exhaust stale air.
There are three main categories of ventilation hoods: downdraft, updraft wall mount, and updraft island mount. Different types of ventilation systems are best for kitchens, including intermittent extractor fans, continuous extractor fans, and cooker hoods with extractor fans. Ductless range hoods are often preferred for kitchen ventilation as they clean the air when venting to the exterior is not possible.
Continuous ventilation is possible with controlled mechanical ventilation (VMC) that allows air to be renewed. External ducted venting systems consist of a range hood mounted above the cooking surface and a duct that filters the air. There are three types of ventilation systems: a ventilation hood, a range hood, and an exhaust fan. Ventilation efficiency is measured by how many exhaust hoods, plenums, and energy recovery coils can be configured to maximize kitchen safety and efficiency.

What ventilation is required in a kitchen?
When choosing a commercial kitchen ventilation system, it is essential to consider factors such as size, type of cooking equipment, and the type of cooking process. Larger kitchens may require a mechanical extraction system with a fan and filter, while smaller kitchens may have air supplied through ventilation grills. Professional industrial systems should be chosen and maintained to ensure optimal performance. Heat and plumes also play a significant role in the ventilation system, and it is crucial to consult with a kitchen designer or installer to ensure equal air volume is used.
This also impacts the choice of HVAC system. The HSE advises against using freestanding fans as a ventilation method, as they can create air turbulence, spread harmful bacteria, cause trips, or pose an electric shock hazard. Therefore, it is essential to choose the right ventilation system for your kitchen.
What is the best type of kitchen ventilation system?
Updraft ventilation is a common type of kitchen ventilation that allows steam to rise into a filter system, which is then extracted and sent outside. In contrast, island ventilation operates in a manner that is analogous to that of the aforementioned system, albeit with a heightened degree of criticality in island applications. This is due to the influence of cross drafts on the surface area of the hood, which can lead to a notable enhancement in performance.
Which type of exhaust system is used in kitchen?
An exhaust fan is essential in maintaining kitchen cleanliness, expels heat from cooking, and removes smoke and unpleasant odors. These odors are harmful to our health, especially to the lungs. Installing an exhaust fan improves air quality and prevents bad odors from circulating. There are various types of fans, including blower and impeller types, with the blower type being more popular. Exhaust fans are energy-efficient, saving on power bills and running quietly without disturbing family members. There are various types and sizes available, making it convenient to choose the one that best suits your needs.
Kitchen hoods, which come in various shapes and sizes, accumulate grease-laden vapors that must be removed periodically throughout the year, depending on the type of cooking equipment used. Choosing the most suitable exhaust fan type can lead to health benefits and reduced costs.
What is the best way to vent a kitchen?
To enhance kitchen ventilation, it is recommended to invest in a high-quality range hood, ensure its appropriate sizing, consider external duct ventilation, prioritize maintenance of cleanliness, utilize open windows and doors, strategically utilize cooking appliances, install a ceiling fan, and employ the use of cooking lids.
How do you vent a kitchen exhaust to the outside?
The optimal method for venting a range hood is vertically through the roof, as this is the direction in which hot air rises. In the event that this is not a viable option, the next most suitable location for the vent is a side wall. The cost of installing a new range hood varies considerably, depending on the complexity of the installation. It typically ranges from $200 to $500. The mean expenditure for a vent hood is approximately $750, which excludes the costs of parts, ductwork, and electrical work.
What type of ventilation is for kitchen?
Updraft ventilation is a popular choice for kitchens due to its ability to allow steam and warm air to rise into a filter system, which is then extracted from the kitchen and sent outside. The capture area of the hood is crucial, and it is recommended to choose an oversize hood by one size. Professional range products and tops require a deeper back to front hood, which increases the capture area. All hoods have some type of filter, such as mesh aluminum, stainless baffle style, or grease trap style containers. The best practice is to choose an oversize hood by one size, considering the amount of cubic feet of air per minute (CFM) it extracts.
What is the basic ventilation for a kitchen?
The hood captures heated air from the cooking surface, including gaseous, liquid, and solid contaminants. A key component is the grease filtering system, which includes mesh filters, baffle filters, cartridge filters, water wash, continuous water mist, and UV (UV) lights. Mesh filters trap grease and contaminant particles, while baffle filters separate grease from air streams and can be cleaned in dishwashing machines. Cartridge filters are suitable for moderate to heavy grease environments and can be cleaned in commercial kitchen dishwashers.
Water wash cleans cartridges in an automatic internal washing cycle, while continuous water mist is an effective grease removal system using cold water sprayed into the extraction system. UV technology integrates UV lights into the hood, breaking down grease molecules into smaller compounds of carbon dioxide and water vapor and releasing them through exhaust airflow. Three types of exhaust fans are typically found in commercial kitchens.
What is natural ventilation in kitchen?
Natural ventilation is a method that promotes air flow in indoor spaces without the use of mechanical systems like fans or air conditioners. It relies on wind and buoyancy to circulate fresh air and expel stale air, aiming to maintain a comfortable and healthy indoor environment by regulating temperature and dissipating moisture and odours. Passive ventilation uses architectural elements like windows, vents, and chimneys to allow air to move naturally. Wind creates pressure zones on a building’s surface, which can be facilitated by vents or openings on opposite sides of a room.
What are the ventilation systems in the kitchen?
Kitchen ventilation equipment, such as extractor hoods and filtering systems, is crucial for maintaining a comfortable and safe working environment. It should remove cooking fumes, introduce cool, clean air, and prevent stress. The fan may be located in the kitchen or ducts. Proper ventilation ensures air movement is not uncomfortable, provides sufficient air for complete combustion, and prevents carbon monoxide accumulation.
The system should be easy to clean, quiet, and vibration-free to prevent fat residue accumulation and increase efficiency. The design of an effective kitchen ventilation system is determined by various factors.
What is the name of the kitchen exhaust?
An extractor hood is a device used to contain rising gases, also known as the “effluent plume”, in the kitchen. It consists of a skirt or capture panel, a grease filter, and a fan for ventilation. It can be ducted or ductless, with ductted hoods blowing gases outdoors and ductless hoods filtering the air using activated charcoal to remove odor and smoke particles. Other names include cooking canopy, extractor fan, fume extractor, and electric chimney.
What is a kitchen exhaust system?
A kitchen hood is a mechanical fan that hangs above the stove or cooktop in the kitchen, removing airborne grease, combustion products, fumes, smoke, heat, and steam. It is often used in commercial kitchens with fire suppression devices to vent grease fires quickly. Commercial vent hoods can also be combined with a fresh air fan to circulate cooking fumes. Most exhaust hoods have a filtration system to remove grease and other particles.
Some vent hoods recirculate the air to the kitchen, using filters to remove odors in addition to grease. The device is also known as an extractor hood in the UK, range hood in the US, and rangehood in Australia. Other names include cooking canopy, extractor fan, fume extractor, and electric chimney.
📹 Vent Hood Buying Guide: What You Need To Know
In this video, we talk about factors to consider when choosing a range hood for your kitchen.
What about those curved glass chimney hoods? You say that the hood vent area should be the same size of the stovetop but with those curved glass hoods, it seems like the actual vents are WAY too small for the stovetop (look at pics of ex 36inch stoves with 36inch glass hoods and you will see what I mean) and those glass wings are at most decorative (and I can only assume they get greasy below and dusty on top real quick). Then to confuse matters more, the vendors actually include the wing measurements as part of the hood length, ok its the real length required for installing but most of that is non-functional (example a 36inch glass hood really has less than 30inch vents where the air actually gets sucked through.
