In this paper, we report dynamic responses of small organic Rankine cycle (ORC) system with latent heat thermal storage to varying heat sources such as waste heat from industries and automobiles. The PCM used in this study was assumed to be a mixture of Li(NO_3)and Mg(NO_3)_2 ・ 6H_2O with melting point and latent heat of 66℃ and 142.6J/kg (to solid), 70.5℃ and 143.4 J/kg (to liquid), respectively and the spherical capsule was made by Ni-plating of 1mm thickness. Numerical analysis of the small ORC system showed that the system efficiency of averaged 10〜11% obtained (considering pump power) and the mean system output power of 260 to 310W using the almost 3kg PCM.
