摘要
用双集总热容和双等效热阻的模型，讨论了放有蓄冷器的冰箱冷冻室在保冷期的温度特性，给出了蓄冷器温度Ｔｂ，冷冻室壁温Ｔｗ以及冷冻室温度Ｔａ随时间变化的具体关系式，算值与实验作了比较，吻合良好．理论分析的结果，为蓄冷器设计及其与冰箱的良好匹配提供了科学依据．
he thermal characteristics of temperature of a refrigerator with an accumulator of cold are analysed with a twthlump heat-capacity and two effective thermal resitsance method. The temperature equations are obtained for the accamulator (Tb) and for the temperation variations with time of the freezer wall (T.) and the temperature inside the freezer ibelf (Ta). The talcchtion is compared to that of an experiment and there is a gab agreement between them. The resultS of the analySis in acpaper supply a scientific basis for matcning an accumulstor with a refrigerator and deigning a gab ac-cumulators.
