  21. Chiller Plant Control

  22. Tracer Summit Chiller Plant Control • Standard Summit Application Program • Flexible to accommodate a variety of plant designs • Feature rich supports control strategies • Easy to understand user interface

  23. The Value in Chiller Plant Control

  24. Pre-engineered Features • Load determination • Capacity matching • Rotation • Chiller setpoint control • Failure recovery • User interface Reliable chilled water flow

  25. Load Determination (when to add or subtract a chiller) • Match plant capacity to building load • Run as few chillers as possible at optimal efficiency Matched Capacity => Reduce Operating Costs

  26. Load Determination • Constant or variable flow systems • Add logic • Based on Supply Temp and Chilled Water Setpoint • Operator editable delay times and deadbands • Subtract logic • Based on Supply/Return Water Temps or Bypass Flow (for large systems) and Chiller Capacities • Operator editable delay times and deadbands • Custom • Adaptable to suit customer specific algorithm requirements Reduce Operating Costs

  27. Add Example Add timer starts Chiller is added 47.5° 2.5° Add temp deadband Add timer reset 45° Add delay time (10 minutes) Chilled water supply temp System supply setpoint Prevents Unnecessary Cycling

  28. Subtract Example (Temperature) Chilled water delta temp 10° Subtract timer starts Chiller is subtracted Design delta temp 6.2° Subtract timer reset Subtract delta temp 0° Subtract delay time (20 minutes) Prevents Unnecessary Cycling

  29. Subtract Example (Flow) Subtract flow threshold Subtract timer starts Chiller is subtracted 1080 GPM 900 GPM Subtract timer reset Chiller design flow capacity Subtract delay time (20 minutes) Reduce Operating Costs

  33. Rotation (which chiller leads) • Flexible for System Needs • Selected chiller types (Base / Normal) • Calendar based • Other system inputs • Run time based • Manual operator decision Reliable Chilled Water

  34. Current Limit Setpoint Control • Soft Start • Prevents excess capacity on “warm” starts • Pull down the system smoothly • Unload before start • Ride out flow transients during pump control • Variable flow / multiple pump systems • Low supply water temperatures Reduce Operating Costs

  35. Soft Start Example System chilled water supply temperature Chiller plant enabled in the soft start mode 65° Chiller plant transitions from soft startmode to normal mode 20° Soft start deadband 47.5° 2.5° Add temp deadband System supply setpoint 45° Reduce Operating Costs

  36. Failure Recovery keep chilled water flowing • Follow the standard sequence • Multiple failure inputs • Chiller level • System level • Editable time delays Reliable Chilled Water

  41. Take-aways

  42. HVAC System Optimization The meter is on the Park! Reduce Operating Costs

  43. Optimization - the meter is on the Park! • Chiller selection • Tower control • Distribution pumping static pressure control • System soft loading • System setpoint selection • Humidity / comfort compensation Reduce Operating Costs

  44. Optimization - Chiller - Tower Control • Low limit • Protect the tower & chiller • Chiller - tower optimization • Real Time Calculations? • Move less air? • Pump less water? Reduce Operating Costs

  45. Chiller - Tower Control • Trane chillers have a minimum delta P between condensation and evaporation, 5psi within 15 minutes of start-up. Reduce Operating Costs

  46. Chiller - Tower Control what is optimal? • 85°F setpoint minimizes tower energy use • 60°F setpoint minimizes chiller energy use • Wb + 5°F optimizes nothing • We use real time optimization Reduce Operating Costs

  47. Chiller - Tower Control what is optimal? 350 300 Chiller kW 250 Tower kW 200 Total kW kW 150 100 50 0 72 73 74 75 76 77 78 79 80 81 82 83 84 85 Tower Supply Temp Reduce Operating Costs

  48. Distribution Pumping static pressure control • Normally controlled based on system supply / return pressure difference. • Highest system pressure closest to pumps • Highest system pressure at part load • 2-Way valve control stability • Large chiller plant syndrome (leaky valves) Reduce Operating Costs

  49. Distribution Pumping critical valve pressure control • Critical valve reset • Just like VAV Critical Zone Reset but on the water side • Benefits • Reduced pump energy • Better coil control • Extend pump life • Better acoustics Pressure Differential Controller or Transmitter Air Handling Units Control Valves Reduce Operating Costs

  50. Distribution Pumping critical valve pressure control • Requires fully integrated systems • Execution • Monitor critical AHU valve position • Reset distribution static pressure setpoint • Any valve > 90 % open increase setpoint • All valves < 80 % open decrease setpoint Reduce Operating Costs
