Abstract:

In this paper，a thermoeconomic cost model and characteristic equations based on the adequate fuel-product concept of structural theory are constructed for a gas-fired micro-trigeneration system，which uses a small-scale generator set driven by a gas engine and an adsorption chiller.By solving the characteristic equations，the thermoeconomic costs of power，cooling and heating are evaluated according to the experimental data.The analysis indicates that the price of natural gas and the initial investment of adsorption chiller are the main factors in determining the thermoeconomic costs of the micro-trigeneration system.
