HVAC Heating Ventilation Air Conditioner...

HVAC Term used for Heating, Ventilation, and Air Conditioning. he main purposes of a Heating, Ventilation, and Air-Conditioning (HVAC) system are to help maintain good indoor air quality through adequate ventilation with filtration and provide thermal comfort. HVAC systems are among the largest energy consumers in schools. The choice and design of the HVAC system can also affect many other high performance goals, including water consumption (water cooled air conditioning equipment) and acoustics (See Acoustics). The following actions detail how engineers can design a quality system that is cost-competitive with traditional ventilation designs, while successfully providing an appropriate quantity and quality of outdoor air, lower energy costs, and easier aintenance. HVAC Término utilizado para Calefacción, Ventilación y Aire Acondicionado. Los principales objetivos de un sistema de Calefacción, Ventilación y Aire Acondicionado (HVAC) son para ayudar a mantener una buena calidad del aire interior a través de una ventilación adecuada con la filtración y proporcionar confort térmico. Los sistemas de climatización se encuentran entre los mayores nsumidores de energía en las escuelas. La elección y el diseño del sistema de aire acondicionado también puede afectar a muchos otros objetivos de alto rendimiento, incluyendo el consumo de agua (refrigerado por agua de los equipos de aire acondicionado) y acústica. El detalle de las acciones siguientes detallan cómo los ingenieros pueden diseñar un sistema de calidad a comparacion con los diseños tradicionales de ventilación, y l mismo tiempo proporcionar cantidad y calidad del aire exterior, reducir los costos de energía y un mantenimiento más fácil. HVAC Heating Ventilation Air Conditioner From Wikipedia HEATING From Wikipedia A heater is object that emits heat or causes another body to achieve a higher temperature. In a household or domestic setting, heaters are usually appliances whose purpose is to generate heating (i.e. warmth). Heaters exists for all states of matter, including solids, liquids and gases. The opposite of a heater (for warmth) is an air cooler (for cold) (see air conditioning) used to keep the user cooler than the temperature originally surrounding them. VENTILATION From Wikipedia An air handling unit is used for the heating and cooling of air in a central location (click on image for legend).Ventilating (the V in HVAC) is the process of "changing" or replacing air in any space to provide high indoor air quality (i.e. to control temperature, replenish oxygen, or remove moisture, odors, smoke, heat, dust, airborne bacteria, and carbon dioxide). Ventilation is used to remove unpleasant smells and excessive moisture, introduce outside air, to keep interior building air circulating, and to prevent stagnation of the interior air. Ventilation includes both the exchange of air to the outside as well as circulation of air within the building. It is one of the most important fa
