Ventilation Flashcards
is the science of maintaining atmospheric conditions which are comfortable and healthful to the human body.
Ventilation
Benefits
Improved air quality
Cooling
Reduction of odors
Removal of grease
Reduced cost
Efficient ventilation can exhaust airborne contaminants, and harmful gases such as carbon monoxide created from cooking. Improve indoor air quality with a Outside Air Solution from S&P USA creating a better environment for employees and guests by exhausting polluted indoor air and replacing it with clean (sometimes filtered) air
Improved Air Quality
A cooler kitchen can be achieved by exhausting heat in a kitchen created by stoves, ovens and other cooking equipment and replacing it with cooler outside air. This replacement of air can support the air conditioner in supplying flow for the comfort of employees.
Cooling
Cooking food produces a lot of odors, from overcooked or burnt food, the smell of raw ingredients or simply the act of cooking. Together, these odors can create an unpleasant combination in the kitchen that can leak into the dining area. Ventilation exhausts these odors, creating a pleasant environment.
Reduction of Odors
The build of grease in the air can result in a coating of the walls, ceilings, floors and equipment. Specially designed units from S&P USA exhaust grease laden air efficiently, minimizing this issue
Removal of Grease
Reducing the heat in the kitchen reduces the need for cooling from a HVAC system. This lowers the operating costs and overall energy bills.
Reduced Cost
- A group of hazardous chemicals that emanate from solvents, varnishes, LPG stoves, air fresheners, incense sticks and newly renovated buildings
- Are cause in the indoor air in poorly ventilated rooms
Volatile Organic Compound (VOC)
It can be controlled by:
- Use of exhaust ventilation
- Use of low emitting materials to finish and furnish interiors as well as cleaning materials
- Limiting the usage of strong chemicals
Types of Ventilations
Natural Ventilation
Artificial Ventilation
the process of pulling fresh air into a building from the outside
Natural Ventilation
Disadvantages
- Windows cannot be used in certain types of weather e.g rainy, windy, stormy
- It may be possible to position and arrange equipment so that windows can be used for ventilation
- Open windows allow dust, dirt, flies, and other pests into the kitchen
- No form of natural ventilation can keep out bad odors and fumes
Advantages
- Cheap
- It provides light during the daytime
circulate fresh air using ducts and fans, rather than relying to air coming from the small holes.
Artificial Ventilation
There are some ways to achieve adequate artificial ventilation:
A. Exhaust or Extraction System
B. Propulsion System
C. Air Conditioning/ Combined System
