Exergy economic analysis of seawater source heat pump systems

Using exergy economic analysis method, builds up an exergy economic analysis model for seawater source heat pump system. After calculating the exergy flow cost in seawater source heat pump system, finds out that the exergy flow cost of heat pump plant room is the highest. So the exergy flow cost could be reduced by means of improving the efficiency of the heat pump. Suggests that minimal exergy flow cost should be used as a constraint function and the exergy economic analysis method should be applied to the optimization design for seawater source heat pump system.
