  10. TRIGENERATION SYSTEM • Trigeneration or Combined Cooling, Heat and Power (CCHP) refers to the simultaneous generation of electricity and useful heating and cooling from the combustion of a fuel or a solar heat collector. CCHP What changes in absorption chiller than vapourcompression chiller…

  11. ABSORPTION CHILLER Hot source Hot source Condenser Generator Condenser HIGH Pressure LOW Pressure Compressor Thermostatic Absorber Evaporator Evaporator Cold source Cold source The absorption cycle uses a heat-driven concentration difference to move refrigerant vapors (usually water) from the evaporator to the condenser. The high concentration side of the cycle absorbs refrigerant vapors (which, of course, dilutes that material). Heat is then used to drive off these refrigerant vapors thereby increasing the concentration again. Lithium bromide is the most common absorbent used in commercial cooling equipment, with water used as the refrigerant. A Vapour Compression Chiller is a machine that removes heat from a liquid via a vapor-compression refrigeration cycle. This liquid can then be circulated through a heat exchanger to cool air or equipment as required.

  14. DOUBLE EFFECT ABSORPTION CHILLER Hot source Condenser HeatRecovery from engine 90°C LowTemp Generator CCHP High Temp Generator HIGH Pressure HeatRecoveryfrom engineexhaust 150°C LOW Pressure Absorber Evaporator Cold source

  15. HEAT PUMP (HP) To increase the Heat recovery of CCHP, can I use a Heat Pump for cooling the cabinet and the intercoller of CCHP, and increase their heat level (45° to 90°) A Heat Pump (HP) is a device that transfers heat energy from a heat source to a heat sink against a temperature gradient. Heat pumps are designed to move thermal energy opposite to the direction of spontaneous heat flow

  17. MAIN PERFORMANCES OF TGP1 AND TGP2 • 2 * 3 Engines • Single Electric Pw: 580 kWe • Total Electric Pw: 3,480 kWe • Single Heating Pw: 760 kWt • Total Heating Pw: 4,560 kWt • 2 * 1 Absorption Chiller Pw: 1,569 kWf • Total Cooling Pw: 3,138 kWf

  18. HOW TO WORK THE SINGLE TGP Cooling Load is minor than AbsorptionChillercapacity 70% total time - AbsorptionChillerON and cover the coolingdemand

  19. HOW TO WORK THE SINGLE TGP + CHILLER When Cooling Load is greater thanAbsorptionChillercapacity AbsorptionChillerON and ElectricChillerare ON

  20. HOW TO WORK THE LINK BETWEEN TGP1 AND TGP2 TGP1 Hydronicsystem Electricity TGP2 • If the cooling power of one of the two Systems (TGP1 e TGP2) is less than the maximum. Is more efficient produce cooling energy in the absorption chiller and integrate the cooling loads,via link.

  21. HOW TO WORK THE SINGLE TGP + LINK When Cooling Load is greater than AbsorptionChillercapacity 20% total time - AbsorptionChiller ON and Link ON

  22. HOW TO WORK THE SINGLE TGP + LINK + CHILLER When Cooling Load is greater than AbsorptionChillerand Link capacity 10% total time - AbsorptionChiller, Link and ElectricChiller are ON

  23. CONCLUSION • For Elettra and Fermi Lightsources the actions to improve energy efficiency are: • Maximize the use of the thermal energy • The adoption of trigeneration systems to take advantage of the heat produced in summer and middle season. • The adoption of double-effect absorption chiller to maximize cooling capacity. • The logics of operation and support of various systems. At the moment we are monitoring and collecting data that will be presented soon as possible. (Parallel Session A4)
