EA-SAS Cooling

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. 


  • 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 instalment of variable frequency drives, new or more powerful condensers, and others) is collected.
