Abstract: This paper introduces a kind of phase change material and ice-reserving composite refrigeration system for mine-used rescue capsule. A preferred phase change material and ice-reserving composite refrigeration system is verified through the experiment. The heat transfer coefficient of rescue capsule with inorganic of phase change material in the inwall is less 0.425 W/（m²·K) than previous rescue capsule which has only thermal insulation material. The rescue capsule passed the human simulation experiment with environment temperatures of 55 ℃，24 h；30 ℃，82. h.
