Fundamental study of cold heat-storage system of O/W-type emulsion having cold latent-heat-dispersion material. Part 1
- Okayama Univ. (Japan)
This paper deals with thermal properties of an oil (tetradecane, C{sub 14}H{sub 30}, melting point 278.9K)/water emulsion as a latent heat-storage material having a low melting point. The measured results of the physical properties of the test emulsion, that is, thermal conductivity, specific heat, latent heat, and density, are discussed for the temperature region of solid and liquid phases of the dispersion material (tetradecane). It is clarified that Eucken`s equation can be applied to the estimation of the thermal conductivity of the emulsion. Moreover, it is established that tetradecane as the dispersion material exhibits a supercooling phenomenon which influences the thermal properties. Useful correlation equations of the thermal properties for the emulsion were proposed in terms of temperature and concentration ratio of the emulsion constituents.
