Siemens equips its Intelligent Valve with glycol capability and change-over function

Thanks to the newly integrated dynamic control change-over function, a heat exchanger can be dispensed within the assembly of AHUs. Intelligent Valve has two different parameter sets: one for heating, and one for cooling. This allows ideal operation in cost-effective and space-saving applications like combined coils in AHUs or combined distributions. With its new control function for changeover applications, the Intelligent Valve automatically detects whether it is in heating or cooling mode and optimizes quantities such as volume flow or ΔT. This change-over function saves engineering time and investment costs at the automation level. The new function allows ventilation centers to be optimized, AHUs to be downsized, and ultimately space to be saved that can be used for other purposes.
