HVAC is important within the development of medium sized to sizeable manufacturing and large office buildings such as skyscrapers plus marine environments for example , aquariums, where safe and healthy building conditions are governed with respect to temperature and humidity, using fresh air coming from outdoors.
The main reasons for a Heating, Ventilation, and Air-Conditioning (HVAC) system are to help maintain high indoor quality of air by adequate ventilation with filtration and provide thermal comfort. HVAC systems are among the largest energy consumers in schools. The selection and design of the HVAC system may also affect many other high performance goals, such as water consumption (water cooled air conditioning equipment) and acoustics
As energy supplies dwindle and production charges and demand rise, the cost of electricity and gas are likely to increase. Brand new air conditioning and heating devices are slowly becoming a lot more efficient. If you incorporate the efficiency of a new air conditioning and heating system (using up to 50% less electricity or fuel) with the replacement or sealing of leaky ductwork (saving up to 27%, depending on the condition), you can save a lot of money on your monthly energy bills.
Heating: Central heating is normally used for cold places to warm private houses and public buildings, a furnace room in a house or a mechanical room within a large building, The use of furnaces, space heaters and boilers as ways of indoor heating may lead to incomplete combustion along with the emission of carbon monoxide, NOx, formaldehyde, VOC's and other combustion by-products. Incomplete combustion develops when there is insufficient oxygen; the inputs are fuels containing a variety of pollutants and also the outputs are the harmful by-products, most dangerously carbon monoxide that is a tasteless and odourless gas which has severe adverse health consequences when inhaled
Ventilation: Ventilation includes both the exchange of air together with the outside as well as movement of air in the building. It's one of the most crucial factors for sustaining acceptable indoor quality of air in buildings. Methods for ventilating a building can be split up into mechanical/forced and natural types. "Mechanical" or "forced" ventilation is supplied by an air handler and designed to control indoor air quality. Extra humidity, odours, and contaminants can be controlled via dilution or substitute with outside air.Yet, in humid conditions much energy is required to remove excess moisture from ventilation air, Natural ventilation is the ventilation of the building with outside air without using fans or any other mechanical systems. It is usually achieved with openable windows or trickle vents when the spaces to ventilate are small and the architecture allows. In complex systems warm air inside the building can be allowed to rise and flow out upper openings to the outside, making cool outside air to get drawn into the building naturally through openings in the lower areas.
Air conditioning: Air conditioning and refrigeration are provided through the removal of heat. Heat can be removed through radiation, convection, and by heat pump systems through the process known as the refrigeration cycle. An air conditioning system, or just a standalone air conditioner, gives cooling, ventilation, and humidity control for all or a part of a house or building.
A HVAC system combines all three of the systems meaning you don't have to purchase and run all three separately.
