本文介绍了风冷式H2O-LiBr吸收式制冷机的最新发展阶段。开发方法基于先进数值和实验技术的系统应用，并考虑到经济标准。在之前开发的吸收式制冷机概念的实验室原型中，为设计/预测目的实施了两个不同详细程度的数学建模，并通过实验验证:（1）基于不同元件中质量和能量的总体平衡，对吸收循环进行建模；（2） 吸收循环换热器的建模，该模型考虑了半经验公式所暗示的比热和传质过程- 经验模型。同样的模型已应用于一个新的工业化前原型。单位:SICitation:ASHRAE Transactions，第114卷，pt。2008年1月1日，纽约

This paper explains the up-to-date stage of development of an air-cooled H2O-LiBr absorption chiller. The methodology of development is based on the systematic application of advanced numerical and experimental techniques, taking into consideration economical criteria. In a previous development of a laboratory prototype of this concept of absorption chiller, two levels of mathematical modelling of different degree of detail, implemented for design/prediction purposes, were experimentally validated: (1) modelling of the absorption cycle, based on overall balances of mass and energy in the different elements; (2) modelling of the heat exchangers of the absorption cycle, that take into account the specific heat and mass transfer processes implied by means of semi-empirical models. The same models have been applied for a new preindustrial prototype.Units: SI
