Balancing Valves
If we take a look at the overall energy split pie chart for most sites, we can easily notice that the HVAC is the most consuming sector among all other energy sectors. Having an efficient HVAC system does not merely depend on installing efficient chillers and boilers. Balancing the pressurized closed loop circuits that connect these boilers or chillers to the end-user rooms is the master parameter for having HVAC efficiency really put in practice.
Usually, these closed loops are initially pressurized to an average optimal bar and flow level. The cold or hot fluid exit the chiller or boiler to the radiators or fan coil units in end-user rooms. Inside these rooms the actuators and room thermostats open and close the heating and cooling units as per the user’s requirements. This unpredictable and random opening and closing of the fan coil units and radiators creates severe energy inefficiencies due to fluctuations in the set bar and flow levels in the closed-loop circuits.
Being the premium partner of the world leading brand Danfoss, our portfolio offers a wide range of balancing valves including the manual valve DRV, delta P Valves, butterfly valves, Automatic Pressure controllers, and Pressure independent balancing valves PICV (known as AB-QM at Danfoss).
Even if some HVAC systems embed traditional balancing valves for pressure and flow control, it is always a dilemma to control the flow without affecting the pressure. The maximum authority of valves in traditional systems is 50%. To overcome this problem, Smart Age offers Combined PICV Pressure Independent Balancing and flow Control Valve giving the designer 100% authority hence maximum efficiency. With these valves, exhaustive flow and pressure calculations are not needed anymore, since no matter when & how the flows are changed, the differential pressure among the valves remain constant!
