Performance analysis for the characteristics of CHP system (micro gas turbine + hybrid type absorption chiller).

Author(s) : PIALAGO E. J., ZHENG X., YOU D. Y., et al.

Summary

The characteristics of the cogeneration system combined micro gas turbine (MGT) and the hybrid absorption chiller are studied numerically to find the optimal working conditions. As the partial load of cooling decreases, the fuel consumption ratio decreases. Using the heat portions of MGT exhaust gas and increase the heat of the water, the ratio of the fuel savings and COPf also increase. In the full load cases and 50% cooling load cases, the fuel savings ratio are 0.22 and 0.84, COPf are 1.29 and 5.09 respectively. In the case of 100 to 60% partial load, the largest portion that absorbs heat in the absorption chiller when operating are ranked as follows: first, is the burner heat; second is the hot water; and third is the exhaust gas of MGT. But under the 60% partial load, the hot water is first in order while the burner heat is the last. In the case of full load, the exhaust gas of MGT has no effect on the absorption chiller. However, as the partial load of chiller decreases, the exhaust of the MGT shows a larger effect on the absorption chiller.
