摘　　要：根据换热网络多温差设计法所依据的热力学原理及门槛问题的性质特点首次对此问题的多温差设计法作了研究，将其划分为“夹点型”门槛问题和“非夹点型”门槛问题二大类，并作了相应的定义，确定了适用的设计方法。通过实例证明：本文所定义的不同类型的门槛问题是正确的。The multi temperature approach design method for the heat exchanger networks (HENs) with threshold was researched according to the thermodynamic principle based by this method and the features of the HENs. Not only the two kinds of pinch and non pinch threshold are divided and defined, but also the matching design methods are affirmed. The example illustrated that compared with single temperature approach design method, the method can design the HENs with lower investment cost.
