2024 ASHRAE TECHNOLOGY AWARDS CASE STUDY
INNOVATION
With artificial intelligence that combines ongoing
monitoring with established RCx protocols, a tailored
real-time analytics platform of continuous MBCx was
installed for acquiring operational data as well as
analyzing chiller plant performance. The MBCx was
established with 86 operational rules in operations,
maintenance, sensors and control logic (Figure 1). This
process was designed to identify operational issues,
faulty equipment and subtle controls issues that
impacted the chiller plant's performance.
Major issues identified included: 1) Failed and
manual-overridden equipment, high cooling tower
leaving water temperature, improper settings for fan
speed of cooling tower, etc. (Operations); 2) Mismatch
of VSD control and feedback, high condenser approach
temperature of chillers, etc. (Maintenance); 3) Field
sensors with no received signal and out of range, etc.
(Sensors); and 4) Equipment short cycling, mismatch
of cooling load and capacity, high energy cost for
chiller operation selection (general service tariff vs.
large power tariff) operated in race days and nonrace
days (Control logic). Overall, the innovation of a
monitoring-based commissioning system in a chiller
plant control system can greatly improve the efficiency,
reliability and cost-effectiveness of the facility.
ENVIRONMENTAL IMPACT
The removal of air-cooled chiller plants from the
roof of the STRC Grandstand resulted in a significant
reduction in environmental impact on noise,
vibration, thermal plume and waste heat pollution.
The upgrade to a centralized, water-cooled chiller
plant and RCx through MBCx resulted in a large
amount of electricity savings, leading to a noticeable
reduction in total carbon dioxide (CO2) emissions.
The annual reduction of CO2 emissions was estimated
to be around 1,827 tCO2e, based on local power utility
company CLP's 2021 data, which assumed an indirect
CO2 emission intensity of 0.57 kg CO2e per kWh.
