EA SAS - Digital Twin

Technological Process Perfection by Energy Advice 

a

EA-SAS solution for energy-intensive industries based on digital twin technology.

A digital twin is a virtual copy of a device, process, or system — a mathematical digital model that describes a physical system. All information and indicators related to product quantity, quality, technological and energy efficiency are collected and analyzed in real time, in one platform EA-SAS. EA-SAS automatically reads the required data from SCADA and other databases, controllers and performs the necessary calculations based on this data and increases control efficiency.

With the help of EA-SAS, it is easy to create a digital twin for a refrigeration or ventilation system, a biofuel boiler, a glass melting furnace, heating networks, buildings or a production process. Depending on the Customer’s wishes, a digital twin of one engineering system, object or the whole factory is possible.

It is optimal management that increases technological and energy efficiency and thus reduces unreasonable costs

EA-SAS Cooling is a Digital Twin of the cooling/refrigeration system, designed to reduce electricity consumption through continuous system monitoring and automatic Set Points control.

Digital Twin for various system configurations:

  • Different refrigerants: ammonia, CO2, HFCs (hydrofluorocarbons, e.g. freon);

  • Screw, reciprocating and other compressors;

  • Dry expansion and liquid overfeed systems;

  • Various types of condensers and evaporators;

  • Single compression and multi-compression cycles;

  • Different applications: freezing, chilling, cold storage, air conditioning, air drying and other.

EA-SAS is the answer to:

  • How to reduce electricity consumption?

  • How to control Cooling/Refrigeration process according to variable product quantity and product type?

  • How to track the real efficiency indexes (EER, COP) online and know the real-time state of the system?

  • How to determine actual minimal costs needed to ensure technological requirements and avoid surplus energy consumption?

EA-SAS Cooling functionality:

  • Calculation and tracking of refrigeration energy consumption;

  • Predicting refrigeration demand;

  • Calculation and tracking of Compressors operation state and KPI’s: COP, isoentropic and volumetric efficiency and other;

  • Calculation and tracking of Condenser efficiency;

  • Calculation and tracking of Evaporators efficiency;

  • Required evaporation temperature control Set Point recommendations;

  • Required condensing temperature control Set Point recommendation;

  • Equipment deterioration monitoring;

  • Demand-response and price-based optimization. 

Benefits:

  • Constant refrigeration system maintenance is ensured without additional costs for qualified personnel;

  • Measures for reducing Refrigeration system energy consumption are determined;

  • Refrigeration system efficiency is automatically calculated and tracked;

  • User is informed about a tendentious drop of refrigeration system efficiency;

  • Presented information about equipment deterioration helps to prevent larger failures, plan maintenance repairs and costs.

  • Routine equipment maintenance (such as condenser cleaning, ice release from evaporators) is recommended based on actual need;

  • Actual cooling usage is tracked and compared with historical data, the user is notified about surplus cooling consumption;

  • Important information that helps to justify needed refrigeration system investments (an installment of variable frequency drives, new or more powerful condensers, and others) is collected.
