摘要本文在一个小型的气泡泵驱动的溴化锂吸收式循环的基础上设计了一种采用太阳能和燃气联合驱
动的空调热水两用装置。首先来对吸收式循环的主要换热部件进行了传热与热力计算,算出了各个换热器
的换热面积以及换热管数。在此基础上,对该装置的关键部位—气泡泵进行了设计计算,按照有关的数学
模型,对气泡泵的直径、提升高度、浸没高度等参数进行了计算。然后,根据全年的太阳能热辐射强度估
算出了所需太阳能集热器和蓄热设备的容积。

Abstract Based on a bubble pump driven absorption cycle, this article designed a air conditioning-hot water dual
purpose installation co-driven by solar energy and natural gas in ordinary household use. The heat transfer
calculation was carried on the installation’s ponents, each heat exchanger's heat transfer area was
figured out as well as its tube number. Then, the ponent of this installation- bubble pump was
designed, its main parameters such as the diameter, the lift height and the immersed hight were calculated. And
according to the annual solar energy radiant intensity , the area of the solar energy collector and the volume of
thermal energy storage vessel were estimated.
