A louver is provided in an area where mechanical equipment located inside the building requires ventilation or fresh air to operate. They can also serve as a means of allowing outside air to filter into the building to take advantage of favorable climatic conditions and minimize the usage of energy-consuming HVAC systems. Curtain wall systems ...
AMCA Publication 501 - Application Manual for Louvers provides general information and comments on factors to be considered when designing or specifying installations requiring louvers. It also serves as a guide to understanding the various types of louvers available and includes items to be considered to ensure their proper use.
If they are located closely together, supply air may mix with stale air, decreasing the efficiency of the HVAC system, and creating air quality problems. System imbalances occur when components of the HVAC system are improperly adjusted or installed and can create pressure differences (too much-circulating air creating a draft or too little ...
Vertical section through a commercial building using HVAC plenum instead of airspace plenum. When both the supply and return ducts are constructed in this manner, it is possible to insulate the ducts and the dropped ceiling so that the upper airspace is not heated or cooled, increasing energy efficiency. This is a fully enclosed plenum.
Clean air delivery rate (CADR) is the amount of clean air an air cleaner provides to a room or space. When determining CADR, the amount of airflow in a space is taken into account. For example, an air cleaner with a flow rate of 30 cubic metres (1,000 cu ft) per minute and an efficiency of 50% has a CADR of 15 cubic metres (500 cu ft) per minute.
The California Air Pollution Control District Act of 1947 allowed 1 or more counties to form air pollution districts. [5] [6] The California Bay Area Pollution Control Act of 1955 created the Bay Area Air Pollution Control District. [5] [7] The California Mulford-Carrell Air Resources Act of 1967 resulted in the creation of 11 air basins. [5] [8]
Passive ventilation is the process of supplying air to and removing air from an indoor space without using mechanical systems. It refers to the flow of external air to an indoor space as a result of pressure differences arising from natural forces.
Modern louvers are often made of aluminum, metal, wood, or glass.They may be opened and closed with a metal lever, pulleys, or through motorized operators. [3]The Australian Standard specifies requirements for the construction of buildings using louver in bushfire-prone areas in order to improve their resistance to bushfire attack from burning embers, radiant heat, flame contact and ...
