摘要:Energy conservation can be achieved by the reduction of consumption of energy by optimize the maximum of an energy service. This can be achieved by using energy more efficiently and reducing losses of parts of energy. The components and performance of component used in energy transfer process both should be optimum. One of energy transfer components is duct. Ducts play important role in field of HVAC and other flow device. When fluid flow inside the duct there chances to loss of heat energy and pressure energy. So need to reduce the losses from duct and improve the performance of ducts. For making duct more effectively, need to well known about performance parameter and ways optimization. So, an effective study of performance parameter required to optimize duct and reduce losses of energy.
