EA-SAS Cooling

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