问答题

电冰箱利用制冷剂作为热的“搬运工”,把冰箱冷冻室里的“热”“搬运”到了冰箱外面.制冷剂是一种很容易汽化的物质.冰箱是利用制冷剂汽化时吸热、液化时放热,在系统内循环流动,达到制冷目的.

电冰箱的电动压缩机使气态制冷剂压缩并把它压人冰箱外面的冷凝管里,在这里蒸气变成液体并放热,放出的热被周围的空气带走.冷凝器中的液态制冷剂,经过一根很细的毛细管缓慢地进入冰箱内冷冻室的管子里(即蒸发器),在这里迅速汽化、吸热,使冰箱内的温度降低.生成的蒸气又被压缩机抽走,压人冷凝器,再液化并把从冰箱内带来的热放出.制冷剂这样循环流动,冰箱冷冻室里就可以保持相当低的温度.

以前,用氟利昂做冰箱的制冷剂,氟利昂如果从冰箱中散逸、泄漏出来,上升到臭氧层会破坏那里的臭氧层.对地球的生态环境构成威胁.臭氧层能大量吸收太阳射来的对生命有害的紫外线,是地球上的生物得以生存和进化的重要条件.因此,技术人员研制出了新型的绿色环保制冷剂.现阶段家用电冰箱主要使用异丁烷等环保性能好的制冷剂.

请你回答:

(1)打开冰箱门,能看到冒“白气”,这“白气”是______形成的.

(2)电冰箱是根据液态制冷剂进人冰箱的______后,发生______时吸收热量来制冷的.

(3)通过阅读,你认为蒸发器和冷凝器分别在冰箱的内部还是外部?
