The FlowCon Energy FIT System measures energy usage while monitoring performance to adjust the PICV to optimize chiller performance. The PICV maintains the correct flow despite pressure changes and guarantees that flow and actuator position only change when demand requirements change or water ΔT is outside of specification.
The FlowCon FIT is fully customizable and allows selection of components that work best to optimize the applica tion’s unique energy goals. It consists of a FIT Intelligent Interface and a SM actuator. The FIT Interface has control logics based on sensor inputs and feedback from the actuator. The sensors used for the FIT System are two PT1000 temperature sensors and two 25 bar pressure sensors measuring relative to atmospheric pressure. The tempera ture sensors provide the FlowCon FIT with measurements of up- and downstream temperature, and the pressure sensors measure the ΔP across the PICV allowing the BMS to reduce system pressure to save pump energy when pressure drop is higher than the PICV’s requirements.
When the FIT System is set up with pressure and temperature sensors, inlet- and outlet temperatures, static and differential pressures, flow rate and BTU will be readable in the Building Management System through the BAC net objects. Also, the control objects can be controlled through the BACnet interface. For full detailed information, please see FlowCon FIT BACnet PICS.
If combined, a BACnet compatible SM actuator and the FIT Intelligent Interface will give you access to remote pro gramming of the SM actuator via BACnet. Furthermore, notifications from the SM actuator are routed through the FIT to the BMS system for remote monitoring. In addition, the BACnet compatible SM actuator will show a variety of information incl. sensor data in its display for local access.
There are 3 main control modes for the FIT module: direct ΔT Control, direct Comfort Control, and Smart Control. ΔT Control adjusts the flow through the valve with the aim of maintaining a set design ΔT in the hydraulic system. Comfort Control allows you to adjust the control signal of the actuator directly and thereby control water flow rate like a standard control valve. And Smart Control uses a dual layer control characteristic. The main control is changing the flow to optimize the room temperature relative to the room temperature target. When the room temperature is within the accepted range, the ΔT control is activated to optimize the water ΔT.
Finally, the FlowCon Energy FIT System has local Bluetooth® access in immediate vicinity of the FIT Interface that can be used through the FlowCon App. The FlowCon Intelligent Interface calculates the BTU and displays the data via Bluetooth® on an Android or iPhone mobile device. In the FlowCon App you may connect to the FIT System by tapping “Connection” and “Search” for FlowCon systems around. Follow the steps in the App menu and press “Add”. This way, you can monitor T1, T2, ΔT, P1, P2, ΔP, Flow, BTU and ΔT target.
