Аннотация

A combined cooling, heating and power plant (CCHPP), composed of an endoreversible closed Brayton cycle and absorption refrigerator, is studied in this paper. By introducing the finite time thermodynamics, the formula of the exergy output rate (EOR) of the CCHPP is derived. With the help of Powell arithmetic, the compressor pressure ratio of the Brayton cycle and distributions of 7 heat exchanger heat conductances (HEHCs) are optimized, and the maximum EOR of the CCHPP is obtained. It shows that the hot-side HEHC is the largest one among the discussed HEHCs, and several parameters, such as the total HEHC and ratio of heat reservoir temperature to the surrounding temperature, on the optimal performances of the CCHPP are analyzed.
