“…Using the water-lithium bromide solution, Elperin et al [30] simulated numerically the simultaneous heat and mass transfer of water vapour into isolated disperse spherical droplets. The authors concluded that the resulting increase of the inter-phase temperature decreases the absorption driving potential, the mass flux and the equilibrium concentration.…”

Solar cooling is an interesting application regarding the use of renewable energy to activate climatization systems. Thermally driven chillers (absorption or desorption systems) use the solar energy to provide heat to the generator of an absorption chiller. In this work, an experimental facility, designed for testing innovative components of a simple effect absorption cooling system, is presented. The study is focused on performance analysis of evaporators and its influence on the overall performance of the machine. Experimental results indicate the detection of some operational difficulties. Due to the particular design of the machine, which contains two evaporators, the distribution of refrigerant mass flow rate is not symmetrical in some cases. Therefore, one of the evaporators could be not operating. This situation explains the decrease of cooling power when it is supposed to have an increasing tendency, according to the thermal power supplied to the generator of the machine.

Various researchers have developed models of conventional H 2 0-LiBr absorption machines with the aim of predicting their performance. In this paper, the methodology of characteristic equations developed by Hellmann et al. (1998) is applied. This model is able to represent the capacity of single effect absorption chillers and heat pumps by means of simple algebraic equations. An extended characteristic equation based on a characteristic temperature difference has been obtained, considering the facility features. As a result, it is concluded that for adiabatic absorbers a subcooling temperature must be specified. The effect of evaporator overflow has been characterized. Its influence on cooling capacity has been included in the extended characteristic equation. Taking into account the particular design and operation features, a good agreement between experimental performance data and those obtained through the extended characteristic equation has been achieved at offdesign operation. This allows its use for simulation and control purposes. Extension d'une equation caracteristique aux refroidisseurs a absorption munis d'absorbeurs adiabatiques
