Information

This model validates the models within Buildings.Templates.Components.Pumps by connecting each pump component to a water loop with a fixed flow resistance, which is sized based on the pump's nominal operating point. Two identical parallel pumps are modeled with either one instance of Buildings.Templates.Components.Pumps.Multiple or two instances of Buildings.Templates.Components.Pumps.Single. The multiple pump component is configured to represent variable speed pumps with dedicated speed command signals (component pumMulDed), variable speed pumps with common speed command signal (component pumMul) or constant speed pumps (component pumMulCst). The single pump components (pum1 and pum2) are configured to represent variable speed pumps.
