Never used a range hood before? Well, you might be wondering, what is a range hood, and how does it work? Firstly, a range hood is used to produce air inflow into the kitchen to remove cooking brumes, heat, and malodor from your kitchen.
Range hoods have fans and filters fixed inside them. The fan rotates at high speed to collect the grease and brumes from the kitchen. After collecting the smoke and grease
from the kitchen, it passes through vents. The air gets cleaned and purified inside the hood using carbon filters if you have a ductless range hood model and passed into the kitchen again.
The vent hoods are usually either ducted or ductless. Ducted range hoods grab hot gases from your cooking and send them outside your house while bringing fresh air in. Ductless range hoods just recirculate the gases and air already present by purifying them. Range hoods have various parts to clean and purify the air in the kitchen area.
They also have lights fixed into them to brighten your kitchen area. They also have fans and speed regulator switches to maintain speed levels. This article covers the important parts of a vent hood, so it will be easy for you to choose a perfect range hood.
All range hoods and ducted ones will have an electric fan inside them to collect the hot gases from your kitchen. You can easily use the switch on the hood to turn the fan on. After switching on the range hood, the suckers start to suck out all the hot air and grease in the kitchen.
The electric fan rotates at high speed, which usually creates noise. Typically a range hood which is of the size of 200 CFM rotating at high speed will produce around 60 ̊decibels of sound. In contrast, the low-end CFM range hoods will make less noise.
The high-end models come with noise cancelation, and some are noise-free, too, while some models have manually remote-controlled electric suckers with advanced technology. In addition, the range hood works based on the Bernoulli principle.
The duct, or the vent, is used to direct fumes and heat out of the kitchen. As the electric fan sucks all the grease and hot mist out of the kitchen, it is later passed out through the duct and dumped outside the house.
They are usually mounted onto the walls, which are made of steel; in some cases, if the duct is through the walls and not fixed outside, it is made of PVC pipes.
In ductless range hoods, only the fan is responsible for cooling; the air or air conditioning is used sometimes. Thus some can feel that a ductless range hood is less effective than ducted range hood.
Range hoods, made with advanced technologies, have lights fixed on their base to provide lighting on your stovetop while cooking. This is extremely useful because it can reduce the charring of food, which helps the backend produce low smoke while cooking.
These are usually LED lights, so the electricity used is far less than the heavy voltage ones used in the kitchen. In addition, some high-end models of range hoods have motion sensors and lighting level memory technology so that you don’t have to manually do everything when you have to switch on the lights while cooking.
The hot air sucked by the fans goes into the filters to get filtered. These have small holes where the small smoke particles and grease get held back. The ductless range hoods have charcoal filters to purify the gases to return them to the room.
These filters are usually 2 or 3 layered and need regular cleaning because they get clogged sometimes. If the filters are too clogged, the fan needs to run at extreme speeds to keep up with the purification so that you might use more electricity.
Every range hood model has a selector panel to switch ON and OFF the range hood and the other parts of it. The older and the low-end models still have manual functioning, whereas the high-end and new generation products have remote-controlled and mobile controlling options.
You can regulate the fan speed and lightning brightness from your phone itself. You still get manual options on the panel if the sensors fail.
Firstly, you have various options to start with. For example, range hoods are manufactured in different colors, sizes, and speeds of the fan. Next, you need to have a proper idea of how much CFM you need; this totally depends on how you cook and the time spent on it.
Then you should choose the range of the fan, the duct, and the color texture and materials of the range hood. Finally, measure the proper dimensions of your cooktop and fix the range hood properly.
The distance between these two also has a major impact on the effectiveness of the range hood. Most commonly, the range hood is fixed at a distance of 28 to 36 inches above the cooktop.
As said previously, the range hoods’ look and models depend entirely on the range hood’s cost. Some are metallic colored; some come with enamel painted and matte colors.
The main purpose is to purify the kitchen air and get rid of the fumes, grease to avoid mold and other harmful effects.
So the main intention of having a range hood is to get fresh air and have good health. You can find various range hoods like wall-mounted, ceiling, fixed range hoods, and under cabinets range hood. For a ceiling fixed range hood, the duct should be fixed on top of the roof, where the most preferred range hood nowadays is under the cabinet because it is fixed inside and does not require any extra space leaving the kitchen to look minimal and spacious.
Pick any of these types to add freshness to your kitchen. They require regular cleaning, so clean the filters inside the hood occasionally.
