1) Typical chillers plant efficiency profile 2) Oversized pump without VFD• HVAC system is a key contributor towards energy
consumption.
• Higher variability and higher energy consumption of thechiller plant is leading towards Higher Operational cost

CHILLER PLANT HEALTH MANAGER
6
Chiller plant health manager overlay on existing plant systemmanager that monitors plant performance and detects faultswithout 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 eachdetected fault.
Diagnosis and Prioritization Provides recommendations for corrective action Frequency of energy waste calculations help prioritize the
most urgent issues

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

SUMMARY
12
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.
