For the aspect of energy saving, the significance of energy validity for heat exchanger was elaborated. According to the usage, the heat exchanger was classified to main heat exchanger and secondary heat exchanger. Based on the classiifcation, the major factors affecting energy validity for heat exchanger were introduced, and the common methods of evaluating heat exchanger effectiveness were reviewed. In the light of the present state of our country, the thermodynamic variable method-exergy transfer effectiveness was considered suitable to present technology level, and the principle and applications of the method was profiled. The results will help rating heat exchanger.
