Abstract

The nonuniform thermal conductive reaction blocks were manufactured by impregnation of metal salts on the expanded graphite to improve the heat and mass transfer ability of reaction block for the chemical heat pump using the reaction of ammonia and metal salts(halide). The nonuniform blocks were designated to increase apparent density, like 165, 222, 279, 337, $394kg/m^3$ radially The experimental results showed that the heat transfer characteristics of nonuniform blocks were better than uniform blocks. As the reaction of ammonia repeated, the volumetric expansion in the reaction block makes the mass transfer improve, and the reproducibility better.

암모니아와 금속염과의 기-고 반응을 이용한 화학열펌프에서 열전달 특성과 물질전달 특성을 개선하기 위하여 금속염을 팽창흑연에 반지름 방향으로 겉보기 밀도가 증가하도록 함침시켜 새로운 비균일 열전도성 반응블럭을 제조하였다. 이것은 겉보기 밀도가 반지름 방향으로 165, 222, 279, 337, $394(kg/m^3)$로 증가하도록 만든 것으로 균일 열전도성 반응블럭과 반응특성을 비교하였다. 실험결과 열전달특성은 비균일 열전도성 반응블럭이 훨씬 좋았고, 반응을 반복함에 따라 물질전달과 반응특성이 개선되었으며 반응의 재현성도 양호함을 알 수 있었다.
