摘要：

In order to further improve energy utilization rate, the internal combustion engine combined cooling, heating and power (CCHP) system integrated with absorption dehumidification is studied, of which the economic model is established. Considering the energy, economic and environmental factors, and a multi-objective evaluation criterion is adopted to evaluate the system performance. A fuzzy analytic hierarchy is proposed to optimize and evaluate the system operation strategies and integration schemes. Taking an office building in Guangzhou as an example, the multi-objective evaluation are adopted to evaluate each scheme according to different operation strategies, fuel types and refrigeration methods, and the best integrated scheme will be found. The effects of electricity price and fuel price on the performance of system are also investigated. The result shows: the best scheme is the integrated scheme 3; the office building is suitable for the operation strategy of following the electrical load; the gas internal combustion engine is the prime mover of the CCHP system; the refrigeration system is absorption chiller; the electricity price and fuel price have great influence on the choice of integrated scheme. © 2019, Science Press.
