本文介绍了一种用于住宅和轻型商用新型微通道吸收器传热传质速率预测的实验验证模型的结果。利用该模型预测了通过吸收器的详细温度、浓度和质量流量分布。定义了表面积有效比，以解释潜在的溶液分布和表面润湿问题，从而使模型的预测与测量数据非常一致。这些经过实验验证的分析表明，新型微通道降膜吸收器几何形状可以产生显著紧凑的吸收器，这将有助于在小容量热泵中实现吸收循环。 随着溶液分布的改善，预计一个非常紧凑的0.104×0.104×0.508 m吸收器将很容易转移与住宅热泵对应的负荷。单位:双引文:研讨会，ASHRAE交易，第109卷，第。1.

This paper presents the results of an experimentally validated model for the prediction of heat and mass transfer rates in a novel microchannel absorber for residential and light-commercial applications. The detailed temperature, concentration, and mass flow rate profiles through the absorber are predicted with this model. A surface area effectiveness ratio is defined to account for potential solution distribution and surface wetting problems, which results in excellent agreement between the predictions of the model and the measured data. These experimentally validated analyses show that the novel microchannel falling-film absorber geometry can yield significantly compact absorbers that would facilitate the implementation of absorption cycles in small capacity heat pumps. With improvements in solution distribution, it is expected that an extremely compact, 0.104 × 0.104 × 0.508 m absorber will readily transfer the duty that corresponds to a residential heat pump.Units: Dual
