蒸汽吸收式制冷系统（VARS）的核心部件是吸收器、发电机、冷凝器和蒸发器。泵是VARS的关键部件，用于将制冷剂-吸收剂溶液从低压吸收器循环至高压发生器。热驱动的气泡泵可以由废热或太阳能提供动力，它提供了一种简单而有效的技术，可以将液体从较低的位置提升到较高的位置，然后通过重力下降。在VAR循环中，可以使用气泡泵将溶液从吸收器提升到发生器，还可以解吸制冷剂蒸汽。 为了将气泡泵用于VAR，已经进行了广泛的理论和实验研究。一些分析已经开发了基于空气提升泵，一些没有考虑摩擦因数的影响，两相流，或气体空隙率。假设为层流，这些分析模型中不包括热损失。在这项研究中，开发了一个气泡泵的分析模型，并进行了实验工作，以便在VARS中使用该泵。在模拟模型中，考虑了具有热损失、摩擦、表面张力效应和其他热物理性质的两相湍流流动。该模型通过在大气条件下用水运行气泡泵进行了验证。 对管径为6至10 mm（0.24至0.4 in.）的气泡泵性能进行了研究升力比（管内液体高度与管长度之比）为0.6到0.8，并且在不同的热输入下。实验结果与理论值的一致性在14%以内。在160瓦（0.22马力）热输入、提升比为0.8、管径为10毫米（0.4英寸）的弹状流中获得了最大液体流速。引用:2016年年度会议，密苏里州圣路易斯，会议论文

The core components of vapor absorption refrigeration systems (VARSs) are the absorber, generator, condenser and evaporator. A pump is a critical component of a VARS for circulating the refrigerant–absorbent solution from the low pressure absorber to the high pressure generator. A thermally-driven bubble pump, which can be powered by waste heat or solar thermal energy, offers a simple and efficient technique for lifting a liquid from lower to higher levels, after which it can fall by gravity. In the VAR cycle, a bubble pump can be used to lift the solution from the absorber to the generator and also desorb the refrigerant vapor. Extensive theoretical and experimental research has been performed in order to use the bubble pump for VARS. Some analyses have been developed based on air-lift pumps, some did not consider friction factor effects, two-phase flow, or the gas void fraction. Laminar flow was assumed and heat loss was not included in these analytical models. In this study, an analytical model of a bubble pump was developed and experimental work was conducted in order to use this pump in a VARS. In the simulation model, two-phase turbulent flow with heat loss, friction, surface tension effects and other thermophysical properties was considered. The model was validated by operating the bubble pump with water at atmospheric conditions. The bubble pump performance was investigated with tube diameters of 6 to 10 mm (0.24 to 0.4 in.) and lifting ratios (the ratio of the height of the liquid in the tube to the tube length) of 0.6 to 0.8, and at different heat inputs. Experimental results agreed with theoretical within 14%. The maximum liquid flow rate was obtained during slug flow at 160 watts (0.22 hp) heat input, a lifting ratio of 0.8, and a tube diameter of 10 mm (0.4 in.).
