HVAC (heating, ventilating, and air conditioning; also heating, ventilation, and air conditioning) is the technology of indoor and vehicular environmental comfort. 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, (heating,ventilating and air-conditioning & Refrigeration) or ventilating is dropped as in HACR (such as the designation of HACR-rated circuit breakers).
HVAC is important in the design of medium to large industrial and office buildings such as skyscrapers, onboard vessels, and in marine environments such as aquariums, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors.
Ventilating or ventilation (the V in HVAC) is the process of "exchanging" or replacing air in any space to provide high indoor air quality which involves temperature control, oxygen replenishment, and removal of moisture, odors, smoke, heat, dust, airborne bacteria, and carbon dioxide. Ventilation removes unpleasant smells and excessive moisture, introduces outside air, keeps interior building air circulating, and prevents stagnation of the interior air.
Sheet metal is metal formed by an industrial process into thin, flat pieces. It is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes. Countless everyday objects are constructed with sheet metal. Thicknesses can vary significantly; extremely thin thicknesses are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate.
Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a roll slitter.
The thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its gauge. The larger the gauge number, the thinner the metal. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Gauge differs between ferrous (iron based) metals and nonferrous metals such as aluminum or copper; copper thickness, for example is measured in ounces (and represents the thickness of 1 ounce of copper rolled out to an area of 1 square foot).
Crawl or crawling may refer to:
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.

#Ductwork_Installation. #How_to_Install_Ductwork in a House. #DIY_CAM You will need some basic tools to perform your #air_duct_installation. Most of them are inexpensive and easy to learn how to use. The air duct installation process begins with proper hvac #duct_system design. This is a computerized process of determining the size of hvac equipment for the home as well as designing the duct system. The result is a duct layout plan which shows the size and location of ducts and registers for each level of the home. "Rough-in" Once you have your duct plan, the "rough-in" stage of #air_duct_installation can begin by cutting holes in the sub floor for the ducts and registers. The size and location of supply registers is shown on the duct plan. It is a good idea to keep the holes, for the sup...

http://www.drenergysaver.com | 1-888-225-6260 Climate control and comfort in a home depends on much more than the size, power and efficiency of the heating and cooling system. It depends on proper insulation, air sealing and, above all, it depends on the air duct's distribution and adequate balance between return and supply ducts. Larry Janesky, founder of Dr. Energy Saver, was recently in Central Florida helping a homeowner with a high cooling bills, and uneven temperatures around the house. The bedrooms in his house had only supply ducts. The only return ducts were located in the common areas. Using state-of-the-art equipment, Larry demonstrates how the lack of return ducts in this home's bedrooms was increasing the positive pressure in the rooms above acceptable levels, consisten...
