More about the HVAC Tacoma

by Rossalie Limon Content Writer

Most residential and commercial structures have heating, ventilating, and air-conditioning HVAC Tacoma systems. These systems are also commonly known as mechanical systems. The purpose of most heating and air-conditioning systems is to help maintain a normal comfort zone for the occupants living or working in the structure. In other applications, such as meat lockers, the product may be the reason for environmental controls. The function of ventilating systems is to provide air movement or exchange within the structure. Ventilation is required when excess heat, fumes, moisture, odor, or pollutants must be removed and fresh air replaced.

Most residential structures do not use HVAC plans unless the system is complex, or required by the lending or code enforcement agency. The architect of a commercial or public building often consults with an HVAC engineer for the design, drafting, and installation supervision of the HVAC system. The consulting engineer prepares all of the designs and specifications for the project and the drafter either works directly from written specifications or from engineering sketches. In many cases the engineer prepares rough sketches directly on a copy of the floor plans. The HVAC drafter then creates a new drawing using proper lines, symbols, dimensions, and notes. Some companies use an HVAC overlay where the base sheet is the floor plan and another sheet, known as the overlay, is used to draw the HVAC plan.

How HVAC Systems are Made

HVAC Tacoma systems are made up of mechanical equipment such as the furnace, air conditioner or ventilator, and ductwork. The duct is generally sheet metal pipe designed as the passageway for conveying air from the HVAC equipment to the source. Types of duct shapes include cylindrical, oval, and rectangular. Connectors such as elbows and transition shapes that allow conversion from round to square or rectangular are also used. Any duct shape is possible depending on the application. In most residential applications, standard premanufactured ductwork is used. In commercial structures, the ductwork may be premanufactured or custom-built in a sheet metal shop. Flat patterns are made when custom sheet metal shapes are required. These patterns are made by a sheet metal layout person or a sheet metal drafter. The flat pattern drawings, known as pattern developments, are transferred to thick paper. The paper pattern is then transferred to flat sheet metal to be formed into the desired duct shape. CADD systems are being used to develop the flat pattern and transfer the pattern to the metal. Other industries also make sheet metal patterns. Whenever flat metal is bent into shape, a sheet metal pattern is required. Examples are auto body parts, storage facilities, or electronics chassis components.

HVAC systems are very much important in order to change the temperature of the room according to the requirements.
