Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space.

Its goal is to provide thermal comfort and acceptable indoor air quality.

HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer.

"Refrigeration" is sometimes added to the field's abbreviation as HVAC&R or HVACR, or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers).

Aluminium (aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13.

Aluminium has a density lower than that of other common metals, about one-third that of steel.

It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.

Aluminium visually resembles silver, both in its color and in its great ability to reflect light.

It is soft, nonmagnetic, and ductile.

It has one stable isotope, 27Al, which is highly abundant, making aluminium the twelfth-most common element in the universe.

The radioactivity of 26Al is used in radiometric dating.

Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation.

It is the essence of the secondary sector of the economy.

The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale.

Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers).
