Whois & Analysis for aircomfort.com

Heating, ventilation and air conditioning (HVAC) 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, or ventilating is dropped as in HACR (such as the designation of HACR-rated circuit breakers).

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 fabricated from 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.

Metal fabrication is the building of metal structures by cutting, bending, and assembling processes.

It is a value added process that involves the construction of machines and structures from various raw materials.

A fab shop will bid on a job, usually based on the engineering drawings, and if awarded the contract will build the product.

Large fab shops will employ a multitude of value added processes in one plant or facility including welding, cutting, forming and machining.

These large fab shops offer additional value to their customers by limiting the need for purchasing personnel to locate multiple vendors for different services.

Metal fabrication jobs usually start with shop drawings including precise measurements then move to the fabrication stage and finally to the installation of the final project.

Fabrication shops are employed by contractors, OEMs and VARs.

Typical projects include loose parts, structural frames for buildings and heavy equipment, and stairs and hand railings for buildings.

Construction is the process of constructing a building or infrastructure.

Construction differs from manufacturing in that manufacturing typically involves mass production of similar items without a designated purchaser, while construction typically takes place on location for a known client.

Construction as an industry comprises six to nine percent of the gross domestic product of developed countries.

Building automation is the automatic centralized control of a building's heating, ventilation and air conditioning, lighting and other systems through a building management system or building automation system (BAS).

The objectives of building automation are improved occupant comfort, efficient operation of building systems, and reduction in energy consumption and operating costs, and improved life cycle of utilities.
