Installation and Execution

During the installation, the 75F team encountered challenges owing to dependencies on a co-vendor and delays from using a different HVAC supplier. These issues affected the project timeline and coordination. Despite these obstacles, the team demonstrated resilience by executing 30% of the work at night to avoid disrupting the occupied space and completing the remaining 70% during the day with the client’s support. This collaboration and adaptability ensured that the project progressed smoothly and achieved the desired outcomes despite setbacks.

Dynamic Chilled Water Balancing (DCWB)

Dynamic Chilled Water Balancing (DCWB), offers a specialized control solution tailored for the chilled water line of Air Handling Units (AHUs). By leveraging the heat load demand identified by the Dynamic Airflow Balancing (DAB) algorithm, DCWB optimizes chilled water flow by monitoring temperatures at the inlet and outlet and regulating the Chilled Water (CHW) actuator accordingly. This precise control strategy minimizes chilled water consumption while ensuring the desired temperature levels are consistently maintained. Integration with the Central Control Unit (CCU), existing BTU meter, and a new Actuator further enhances efficiency, leading to significant energy cost savings. DCWB extends the benefits of the fully modulating DAB profile for AHUs, providing multiple approaches to reduce overall energy consumption, encompassing both electrical and cooling aspects. Its unique features include addressing low ΔT syndrome, optimizing heat rejection through higher exit temperatures to minimize energy use, and balancing CHWS for improved chiller efficiency and reduced hydronic pump energy consumption. With customizable approaches, DCWB strikes a balance between comfort and energy savings, offering a comprehensive solution for optimizing chiller system performance under various conditions.
