Improvement of the remote expert system based on software OTEA
Heating and cooling account for a half of the EU's energy demand. In order to fulfil its climate and energy goals, this sector must significantly reduce its energy consumption.
New facilities with a growing number of Heating, Ventilation and Air-conditioning (HVAC) machines producing huge amounts of data now operate in a regime where Machine Learning (ML) models and statistical techniques may be applied.
Before this experiment, a deterministic system with brute force conditions was applied to detect comfort anomalies in more than 3,000 installations worldwide, with 600,000 variables monitored resulting in 3 trillion records for 5 years. The challenge of this experiment was to replace the brute force solution with a superior MLmodel. Like the brute force model the ML model is numerically intensive and needs the use of HPC.
EcoMT´s intention is to address maintenance management by using ML and statistical techniques, to create mathematical models through the analysis and processing of data from hundreds of devices and field sensors. This enables the anticipation of failures and the scheduling of predictive maintenance. These lead to the optimization of processes, the minimisation of downtime and costs and the more efficient use of energy. Due to these needs, the OTEA remote expert system (OTEAres) was developed as an expert remote management system with an aim for energy optimization through the premature detection of incidents based on historical records.
HPC infrastructures offer the required capabilities to support these services and to provide scalable resources when required.
The savings of clients connected to the OTEAres platform operated by EcoMT, would be immediate using ML algorithms and HPC which is essential for real-time operations. OTEAres enables decision support in real time offering a 24/7 service through its control centre, which is the department in charge of controlling the proper functioning of the installations, remotely resolving incidents in the shortest time possible.
Some of the most important results obtained are:
- The update of the deterministic previous version into a new ML model capable of predicting and organising a wider range of incidents.
- A reliable tool for preventing equipment failure situations that might compromise business activities.
- It is estimated an energy saving of 7% per installation, a reduction of 30% in preventive maintenance visits and a reduction of 20% in corrective maintenance.
As a direct consequence, commercial benefits are obtained:
- More than 20% of the incidents registered could be corrected remotely without the need for a technician.
- EcoMT customers can boast a Corporate Social Responsibility Plan and improve their trade image.
- Predictive maintenance will prolong the life of customers' HVAC machines and reduce the number that need to be replaced.
- It is estimated that OTEAres will drive a progressive implementation of electrical panels with enhanced features that will enable remote control. 50% of the facilities are not yet adapted for control. It is estimated that 20% of these facilities will be adapted in 1 year and 50% of these facilities in 3 years, with their subsequent management by EcoMT A A 1-year growth of 20% in EcoMT sales of electrical panels up to 50% over the next 3 years is anticipated.
- EcoMT expects to double the number of controlled facilities in the short term by extending this service to all actual connected installations and to quadruple this number in the long term, with an estimation to produce 1 million euros of total annual revenue.
- Knowledge about the practical performance and usefulness of the predictive models developed by ITMATI/UVigo in real industrial problems.
- Experience in the implementation of mathematical technologies in an energy efficiency context for ITMATI/UVigo.
- EcoMT clients can expect to save up to 7% on their electricity bills due by using the monitoring system.
- More focus can be put on the implementation of control panels in facilities not yet monitored, with an estimation of € 15M of revenue for EcoMT in 5 years including sales of equipment, monitoring and incidence management.
- Managing current installations with OTEAres doubles the annual income to EcoMT, reaching €600.000 per year.
