中文摘要：

内藏式冷柜制冷剂容量较小,系统中制冷剂充注量的变化会对制冷性能产生较大影响。对某型号的内藏柜进行了充注量的试验研究,综合多种因素给出了制冷剂R134A的最佳充注量。通过改变系统中制冷剂充注量,研究了制冷性能参数随制冷剂充注量的变化趋势,为合理确定制冷剂充注量提供了一定的依据。

英文摘要：

Because the refrigerant capacity of built-in refrigerator is small , the change of refrigerant charge quantity in refrigera-tor system will have great influence on the refrigeration performance .The built-in cabinet experiments are carried out to study the charge quantity.The optimal R134A charge is got on the basis of a variety of factors .By changing refrigerant charge quantity in refrigerator system , the change of refrigeration performance parameters with the refrigerant charge quantity was studied , which provides a certain basis for determining the refrigerant charge quantity reasonably .
