ABSTRACT:
A primary-secondary circuit hydraulic interface is disclosed for use in chilled water and hot water systems in which a suction manifold header is used to tie in the secondary return water, the primary supply water, and the suction side of the primary and secondary pumps. The hydraulic interface is installed within the suction manifold at the location where the secondary return water enters the suction manifold. The hydraulic interface allows the bypass water (which is excess primary supply water) and the secondary return water to easily enter the hydraulic interface into a downstream portion of the manifold through large openings and forces the two streams of water to collide together, thereby ensuring a turbulent mixing to take place. The hydraulic interface forces the mixed water to exit the hydraulic interface through much smaller openings into a downstream portion of the manifold, thereby ensuring that the bypass water and secondary return water are thoroughly blended together as they exit. The temperature profile of the blended water is substantially uniform across the pipe diameter of the manifold as the water exits the hydraulic interface.
