Author(s) : SUN Z. G., XIE N. L., YANG W. S., et al.

Summary

A combined cold, heat and power (CCHP) system driven by a micro gas turbine was presented. The output energy of cold, heat and power of the CCHP system was about 46.9, 12.1 and 28.2 kW when 117.2 kW propane gas were consumed by the gas turbine, respectively. The cold and heat could be increased by supplying fuel to burn in the absorption refrigeration unit (ARU) of the CCHP system. The peak cold and heat load of the CCHP system was about 126.1 and 19.3 kW, respectively. Equivalent generated efficiency (EGE) and primary energy rate (PER) were used to evaluate the energy utilization efficiency of the CCHP system. The calculated results shown that the PER and EGE of the CCHP system without gas burning in ARU was about 74.4 and 35.2%, respectively, and saved more than 17.9% of primary energy, compared with conventional separate generation system of the required energy flows.
