PERFORMANCE ANALYSIS OF A MICRO-COMBINED COOLING, HEATING AND POWER SYSTEM BASED ON STRUCTURE THEORY OF THERMOECONOMICS
Combined cooling, heating and power (CCHP) is an attractive technology of sufficient utilization of low-grade thermal energy with the principle of thermal cascading. In this paper, an exergy cost analysis method based on Structure Theory of Thermoeconomics is applied to a LPG-fired micro-CCHP system, which uses a small-scale generator set driven by a gas engine and a new small-scale adsorption chiller. The system can supply 12 kW electricity power and has a cooling capacity of 9 kW or heating capacity of 28 kW. The thermoeconomic model for the system based on the Fuel-Product concept is defined to quantify the productive interaction between different components. The distribution of the resources and costs of all flows in the production structure are calculated by solving a set of equations. The results not only reflect that the Structural Theory is a powerful and effective tool, but also prove that the micro-CCHP is an energy-efficient system.
