Of simplicity, the ELJP model predicts the VLE for HCFC/HFC as well as other weak polar binary systems accurately. However, its parameters are determined by fitting vapor pressure and liquid density data of the pure substance over a temperature range of interest, and are, therefore, temperature dependent.

其缺点是分子的势能模型未能直接反映分子的极性，其参数须随温度而变，且这些参数又是由纯物质的一系列饱和蒸汽压和液相密度的实验数据回归得到，故存在一定局限性。
