  1. Elliott MicroturbinesAbsorption Chiller Integrated System Development Dave Dewis

  2. Overview • Introduction • Elliott TA100 CHP System • Direct Fired Absorption Chillers • System Integration • Test Results • Lessons learned • Future Work • Installations – Ebara MGT Group

  3. Introduction • Commercial Launch of the TA-80 MonoGen system was geared towards support of Solution Providers and tailored installations. • Complexity and redundancy has been eliminated with the launch of the TA100 CHP system while significantly reducing installation time and footprint. • EESI Customers are now looking at more complex Building Integrated systems that incorporate Direct Fired Chillers.

  4. INTAKE SILENCER OIL HEAT EXCHANGER WITH FAN ENGINE / ALTERNATOR ASSEMBLY RECUPERATOR HEAT EXCHANGER POWER ELECTRONICS ELECTRIC ACTUATOR COOLING FAN GAS COMPRESSOR TA100 Integrated CHP Package Dimensions: Height: 78 in Net Power Output: 100 kWe (ISO) Width: 33 in Thermal Output: 172 kW (net) Length: 120 in Exhaust Temp. 535 deg-F (ISO) Dry Weight: 4000 lbs Fuel Input Flow: 22.0 scfm

  5. Microturbine 63 kW Exhaust Gas Outlet Heat Recovery Cold Water Inlet Hot Water Outlet 172 kW Recuperator Losses Compressor Alternator 22 kW Turbine Electricity 105 kW Air Inlet Combustor Internal Gas Compressor Fuel Inlet 362 kW Elliott TA100 CHP Schematic • At ISO conditions: • 100 kW (Net) Electrical • 172 kW Hot Water • CHP Efficiency 75% • MonoGen Efficiency 29%

  6. Direct Fired Absorption Chillers 106 kW Internal Parasitic Load (Pumps): 1 kW 235 kW 35 Tons of Refrigeration Single-Double Effect, (SDE), Absorption Chiller • 35 Tons of Cooling Capacity • COP = 1.03 • Integral damper included • Solution temperature monitoring as Safety Device

  7. Exhaust Gas Outlet 106 kW Cold Water Inlet Heat Recovery Hot Water Outlet 235 kW Recuperator Compressor Alternator 35 Tons Turbine 98 kW Air Inlet Electricity Combustor Internal Gas Compressor 345 kW System Integration Elliott TA100 CHP –SDE Absorption Chiller Integration • Overall Efficiency 63 % @ 70F • Generating hot water simultaneously reduces cooling capacity of absorption chiller

  8. Direct Fired Absorption Chillers Double Effect, DE, Absorption Chiller 235 kW 101 kW Internal Parasitic Load (Pumps): 1.3 kW 40 Tons of Refrigeration • 40 Tons of cooling capacity • COP = 1.04 • Dual Fired System (Burner) • Vacuum reset two/three times a year • Internally pressurized in damper by-pass • Damper and damper controller are not included

  9. 235 kW 101 kW Cold Water Inlet Heat Recovery Hot Water Outlet Recuperator Compressor Alternator Turbine 98 kW 40 Tons of Refrigeration Air Inlet Electricity Combustor Internal Gas Compressor 345 kW System Integration Elliott TA100 CHP – DE Absorption Chiller Integration • Overall Cycle Efficiency 67 % @ 70F • Dual Fired Absorption Chiller integrated with TA100 CHP allows cooling continuously (Burner) while simultaneously creating hot water.

  10. Elliott TA100 CHP SDE Absorption Chiller EESI Integration System used to supply 59F air to test cell for ISO standard day testing.

  11. TA100 MonoGen - DE Absorption Chiller Integration (Sodegaura Plant) • Test Parameters • System start-up transient. • Chiller Cooling Performance at different MGT output power. • Chiller Heating Performance at different MGT output power.

  12. Elliott TA100 CHP - DE Absorption Chiller Integration (EESI Plant)

  13. TA100 Monogen – DE Result(Sodegaura Plant) Measurement shows that it took one (1) hour to have 0 to 40 tons of cooling with burner

  14. TA100 Monogen – DE Result(Sodegaura Plant) Cooling Performance

  15. TA100 Monogen – DE Result(Sodegaura Plant) Heating Performance

  16. Lessons Learned • Overall DE system efficiency, Cooling Mode, tested at 64% • Overall DE system efficiency, Heating Mode, tested at 60% • For heating purposes, TA100 CHP package operates at 75%. • Maintenance requirements vary significantly between manufacturers and should be closely considered. Impact will depend on Customers experience. • Chiller protection methodologies vary between manufacturers, that can impact operational characteristics of the system. • Chiller/CHP integration involves a totally new set of skills, Building Management integration, Water treatment, heat rejection.

  17. Future Work • Completing the TA100 CHP – DE Absorption Chiller installation at EESI for partial thermal load testing, and endurance testing. • Develop and optimize “integration kits” for BCHP solutions. • Support Customer Installations to increase total system knowledge for cost, permitting, and installation improvements. • Review Economic benefit of Integrating Desiccant System.
