As the mechanical engineer for Salinas Valley Memorial Hospital’s Central Plant, Axiom Engineers(sm) provided the detailed design for a “guaranteed savings project”. This project consisted of a new, stand-alone central mechanical plant containing three 140-boiler horsepower thermal fluid heaters with stack economizers, feed water storage tanks, and two 200-horsepower thermal fluid-to-water heat exchangers producing high-pressure steam, which is routed underground to the original boiler room for distribution throughout the building. The building also contains a 350-ton gas engine driven chiller, pumps, and cooling tower. Chilled water is routed underground to the existing chiller plant, which was converted to a true primary/secondary system. The plant was designed to operate automatically without boiler attendants.
