本文研究了油（十四烷，C_（14）H_（30），潜热229 kJ/kg，熔点278.9 K）/水乳状液作为低熔点潜热储热材料的冷放热特性。采用空气-乳化液直接接触换热的方法对含固化十四烷的乳化液层进行放冷。以温度有效性、显热释放时间和潜热释放时间为实验参数进行了测量。以无量纲的乳状液层深度为依据，导出了乳状液层尺寸、气流雷诺数、Stefan数和热容比的无量纲关联式。
This paper deals with cold heat-release characteristics of the oil (tetradecane, C14H30, latent heat 229 kJ/kg, melting point 278.9 K)/water emulsion as a latent heat-storage material having a low melting point. An air-emulsion direct-contact heat exchange method was selected for the cold heat-release from the emulsion layer including solidified tetradecane. The temperature effectiveness, the sensible heat release time and the latent heat release time were measured as experimental parameters. The useful nondimensional correlation equations for those parameters were derived in terms of nondimensional emulsion layer depth, expressed the emulsion layer dimension, Reynolds number for air flow, Stefan number and heat capacity ratio.
