试题解析

溴化锂吸收式制冷机

溴化锂吸收式制冷机,以水为制冷剂,以溴化锂水溶液为吸收剂的吸收式制冷机。主要部件为蒸发器、冷凝器、发生器、吸收器、溶液热交换器和溶液泵、U形管等。蒸发器为高真空容器。水的蒸发能使管内的冷媒水放出热量而降温,获得冷量,所产生的水蒸气流入吸收器。由吸收器泵送来的溴化锂浓溶液有吸收水分的能力,与水蒸气接触即将其吸收,形成稀溶液,并由发生器泵送入真空度较低的发生器。由于水的沸点远低于溴化锂的沸点,因而水分汽化而析出,进入冷凝器,被管内冷却水冷却,凝结成水,然后经U形管节流降压,进入蒸发器进行再一次的蒸发、制冷。发生器内被浓缩的溶液经过溶液热交换器预冷后再进入吸收器,进行另一次循环。这种制冷机的工质无毒、无味、无爆炸危险,能利用如废汽、热水、物料热等低温热源作为动力,因此安全、节能,已在空调工程和需要低温水的生产工艺中广泛应用。

But such ______(57) are getting attention. At the US Obesity Society's annual meeting, one person ______(58) obesity with car accident deaths, and another correlated obesity with suicides. No one asked whether there was really a cause-and-effect relationship. " The funny thing was that everyone took it ______(59)." Oliver said.
