Abstract

一种溴化锂吸收式制冷机冷却水系统属冷却装 置，其主要特征是采取两个吸收器，蒸发器左中右排 列，蒸发器放在中间；冷凝器、低压发生器也采取左右 排列。使用本发明可以使冷却水同时进入吸收器和 冷凝器；进入吸收器和冷凝器的冷却水温度较低，同 时使吸收器的吸收能力增强，冷凝器的冷凝能力增 大，在不增加冷却水总耗量的情况下，可使冷蒸汽的 流通截面增加，减小蒸汽流速，降低了阻力，可用较小 的冷却水量达到同样的效果，同时可使该部位的传热 面积减小30％。

Description

一种溴化锂吸收式制冷机冷却水系统属冷却装置。
本发明作出以前，现有的溴化锂吸收式制冷机冷却水系统均为串联走向。即工作蒸汽压力在4kgf/cm2以上的机组，冷却水先进入吸收器，再进入冷凝器，这样使得进入冷凝器的冷却水温度较高，造成较高的冷凝压力，溶液的浓度不得提高。工作蒸汽压力在4kgf/cm2以下的机组，冷却水先进入冷凝器，再进入吸收器，这种结构虽然降低了冷凝压力提高了冷凝效果，但进入吸收器的冷却水温度升高，不利于吸收，只有大量增加冷却水量，才能达到效果。在蒸发-吸收器排列中采取上下排列;在冷凝-低压发生器中也采取上下排列。在同样的传热面积下，蒸汽流速较大，这样的结构形式不是最佳的。
本发明的目的在于克服上述不足之处，从而提供一种结构形式排列合理，可使蒸汽的流通截面增加、减小蒸汽流速、降低阻力、用较小的冷却水量达到同样效果的冷却水系统。
本发明溴化锂吸收式制冷机冷却水系统主要特征是两个吸收器左右排列，中间是蒸发器;冷凝器、低压发生器也采取左右排列。工作时，冷却水分三部分进入机组。二部分进入两个吸收器，另一部分进入冷凝器，各自完成吸热升温后，出机组进入冷却塔。
附图说明：
图1是本实用新型溴化锂吸收式制冷机冷却水系统结构流程示意图。
下面本发明溴化锂吸收式制冷机冷却水系统将结合附图中的实施例作进一步描述：
本发明溴化锂吸收式制冷机冷却水系统主要由两个吸收器1、蒸发器2、冷凝器3、低压发生器4、高压发生器5所组成。两个吸收器分左右排列，蒸发器2安排在中间，它们的传热管采用紫铜管，胀接在管板上。冷凝器3与低压发生器4左右排列，它们的传热管也采用紫铜管胀接在管板上。吸收器、蒸发器、装在同一筒体内;冷凝器、低压发生器安装于另一筒体内。高压发生器5也单独安装在筒体内。冷却水、冷冻水管外部管道由用户连接。冷却水管道分三路同时进入二个吸收器、冷凝器。在吸收器部位分二至四流程下进上出、在冷凝器部位亦同时分二至四流程左进右出。
本发明溴化锂吸收式制冷机冷却水系统与已有技术相比具有以下优点：1、冷却水同时进入吸收器和冷凝器，进入吸收器和冷凝器的冷却水温度较低;2、吸收器的吸收能力增强，冷凝器的冷凝能力增大;3、在不增加冷却水总耗量的情况下，可使冷蒸汽的流通截面增加，减小蒸汽流速，降低阻力，用较小的冷却水量达到同样的效果，可使该部位的传热面积减小30%。
