2 GREEN CHILLER PLANT Energy Efficiency Superior system performance Less energy consumption versus similar size building Operation efficiency Ease of operation Proactive prediction of system failure. Less efforts to maintain Environment efficiency Use eco-friendly refrigerant 2

3 WHAT IS HAPPENING? HVAC system is a key contributor towards energy consumption. 1) Typical chillers plant efficiency profile 2) Oversized pump without VFD Higher variability and higher energy consumption of the chiller plant is leading towards Higher Operational cost High Usage Variability Vs Design 3) No proper controls system 4) Over-design of systems Low Usage Variability Vs Design Low Energy Consumption High Energy Consumption 3

6 CHILLER PLANT HEALTH MANAGER Chiller plant health manager overlay on existing plant system manager that monitors plant performance and detects faults without affecting control sequences. It is scalable and works with: WebCTRL and i-vu platforms (UTC system) non-utc equipment Tracks frequency, duration and energy waste associated with each detected fault. Diagnosis and Prioritization Provides recommendations for corrective action Frequency of energy waste calculations help prioritize the most urgent issues 6

7 APPROACH Real time analytics based on operational and energy use data Energy Diagnostics Alarm Generation Alarm generated when system operation deviates from optimal Operational behavior Maintenance and repair Retrofit Recommendation for Improvement Estimated Energy Waste Quantified energy saving opportunities Prioritization Tracking to ensure improvement realized Improvement Tracking Dashboard Diagnostics Recommendations Prioritization 7

8 QUANTITATIVE ANALYSIS Alarm persistence time analysis Estimated potential energy saving analysis RL3W16: CHWST set-point is unreasonable. RL1C12: CHWST set-point of each chiller are different. RL3W10: Small temperature range between CHWST and CHWRT. RL3W10: Small temperature range between CHWST and CHWRT, persistence time is about 15,045 minutes and potential energy saving opportunity is about 24,563kWh. RL3W16: CHWST set-point is unreasonable, persistence time is about 26,469 and potential energy saving opportunity is about 20,072kWh. RL2S6A: Small temperature range between CWST and CWRT, potential energy saving opportunity is about 4,058kWh 8

12 SUMMARY 1. Many existing hotels are operating at low chiller plant system efficiency. There is a strong business case for retrofitting buildings. 2. Check your chiller plant system efficiency, it is likely you have low hanging fruits to pick. 3. Chiller plant control optimization system comprehensively considers the performance of all equipment, provides the optimized control strategies and derive significant energy and operational savings. 4. Real time data analytics and diagnostics provides insights into system operational performance and optimizes the control logic based on real time operation to achieve continuous improvement. 12
