Scheme-Selection Optimization of Air-Conditioning Heating and Cooling System Based on Exergy Method

An exergy analysis model of air-conditioning heating and cooling systems was established based on exergy method and thermoeconomic theory. Product exergy cost was proved to be the key factor in evaluating air-conditioning heating and cooling systems. The optimization arithmetic of air-conditioning heating and cooling systems scheme-selection, was proposed after considering the related factors, such as unit product exergy cost, capital expenditure, technology, total floor area, safety and reliability, influence on the environment and maintainability. A project example demonstrated that the proposed arithmetic was more reliable and more distinguishing, compared with the traditional methods.
