Minimise plant power usage
CHILLED WATER PLANTS account for a sig- nificant share of the energy used in buildings.
This session will present Machine Learning techniques to develop an optimal controls strat- egy to reduce energy use while maintaining the required chilled water production.
The strategy identifies in real-time the opti- mal number of chillers, cooling load distribution amongst chillers and condenser water flow set- points that minimise power usage of the plant.
The presenter, Michael Berger, head of R&D at Conserve It, will show how he built a Digital Twin of the plant which updates automatically based on operating data.
Berger said the data relied on data pre-pro- cessing and expert-knowledge-driven con- straints, to capture equipment performance var- iations over time.
Computing efficiency was a core requirement, leveraging the improvements in computing ca- pabilities of Edge devices in recent years, to al- low the solution to be fully deployable on site, without the need for components in the cloud.
This eliminated hur- dles such as on-going fees and security or stability issues that may arise with constant internet connections requirements.
Michael Berger will present the session.
The strategy identifi s the optimal number of chillers and cooling loads.
Results from deployment at several sites will be presented to demonstrate significant ener- gy savings.
As the Head of R&D at Conserve It, Berger leads research, prototypes, and trial machine learning algorithms for analytics and real-time optimisation of live equipment in the built environment.
Applications range from innovative chiller plant optimisation & predictive mainte-
nance to advanced controls solutions. Berger graduated with a Master of Engineer- ing in France before gaining experience at a lead-
ing research centre.
He gained experience at the Environmental-
ly Sustainable Design consultancy in Singapore. He joined Conserve It in 2014, where he relies on years of experience in the fields of Energy Efficiency, Chiller Plant Optimisation and Machine Learning.
Meeting place for industry
THE REFRIGERATION AND Air Conditioning Contractors Association (RACCA) will be par- ticipating in ARBS 2022 sharing a stand with Re- frigerant Reclaim Australia (RRA).
RACCA president Kevin O’Shea said the stand will be used to connect with members from all over Australia.
O’Shea hopes the event will be a place for those interested in taking up a trade to learn more about refrigeration and air conditioning and wel- comes potential members interested in joining RACCA to come over for a chat to learn more about membership.
RRA is the product stewardship organisa- tion for the Australian refriger-
ants industry.
RRA is a not-for-profit organisa-
tion created to work nationally with industry to share the responsibility for, and costs of, recovering, reclaim- ing and destroying surplus and un- wanted refrigerants.
RRA’s aim is to improve the indus- try’s environmental performance by reducing the level of emissions of re-
frigerants through its take-back program. Visit the stand to find out about the Steward- ship Program and the Refrigerant Recovery Sim-
ulation App.
Since being established in 1993, RRA has be-
come integral in the management of used and unwanted refrigerant, and the reduction in emissions of ozone depleting and synthetic greenhouse gas refrigerants.
Created by industry, for industry, RRA has achieved global recognition for its work in pre- venting emissions.
“I will be present and I am hoping the stand serves as a meeting place for RACCA members wishing to have a discussion or mingle. Some of the national executive will be on hand to hear concerns from mem- bers,” he said.
The stand will be shared with RRA with information on how to safely return your refrigerant for de- struction.
