Do you need to use high velocity duct in an induction sytem?

0

No. With the pressure in the plenum of an induction terminal unit being 150 – 250Pa, and no longer 450Pa and much higher, the total pressure in the supply system – the primary air duct system – allows the use of low pressure and low velocity duct sizing and construction. How do you maintain the secondary water temperature? There are three methods that can be considered. Options 1 and 2 below are for systems where all of the cooling for the installation originates at one or more chilled water units, or chillers. The third envisages a separate chiller for the SCHW circuit and will require the use of an energy program for verification. Brief details are: 1. By circulating primary chilled water through a plate heat exchanger with the secondary water passing through the other side. The secondary water pump circulates the full secondary water quantity through one side while a modulating valve controls the primary water flow to achieve the design secondary water temperature.
