Dual Duct System

A dual duct system is a type of air conditioning system that uses two separate ducts to distribute conditioned air throughout a building. The first duct is used to supply cool air to the building, while the second duct is used to return warm air from the building back to the air conditioning unit. This type of system is ideal for buildings that require a large amount of air circulation, as it allows for more efficient cooling and heating. The dual duct system is also beneficial for buildings with multiple rooms, as it allows for the air to be evenly distributed throughout the building. Additionally, this type of system is more energy efficient than a single duct system, as it requires less energy to cool and heat the air.
