COMBINED COOLING, HEAT & POWER – CCHP
Combined production of electrical, thermal and cooling energy
The trigenerative system involves the combined use of Capstone and Century technologies for the combined production of electrical energy, hot water and chilled water through the insertion of a gas turbine and a specific heat recovery module (HRM) for the production of hot water from the exhaust gases of the turbine to feed an absorption refrigerator for the production of chilled water. The hot water produced by the recovery of thermal energy from the exhaust gases of the Capstone gas turbine can be used to feed an absorption refrigerator (chiller) that produces chilled water for use in the air conditioning system or in the process. Chillers use an absorption refrigeration cycle, based on state transformations, in which the refrigerant (water) in combination with the absorbing substance (lithium bromide) reaches the temperatures of a traditional refrigeration system with very low electricity consumption.
The CCHP system ensures a saving of > 30% compared to separate energy production, as well as a considerable benefit in environmental terms, which translates into a significant reduction in the emission of harmful gases such as CO2 into the atmosphere.
