Experimental performances of a LiBr-water absorption facility equipped with adiabatic absorber

Extension of the characteristic equation to absorption chillers with adiabatic absorbers

“…This is also discussed in Kim and Infante Ferreira (2008). The comparison of the two types of absorbers (liquid sheets and droplets as solution spreading mechanisms in the absorber) is discussed in a previous work (Gutiérrez-Urueta et al, 2011), which shows that the liquid sheet has shown better performance parameters than the droplet spray for this working solution. But it can be observed that independently of the configuration used for spreading the solution inside the absorber, the loss in cooling capacity due to the effect of the overflow is observed in both cases.…”

“…(3) and (4) are compared in order to evaluate the quantity of evaporated refrigerant, and therefore the performance of evaporators-absorber combination. The evaluation of the cooling capacity of this facility in a previous work (Gutiérrez-Urueta et al, 2011) indicates evidence of refrigerant overflow on the evaporators. The fraction of refrigerant not evaporated, named m of , gives rise to a loss in refrigeration power, Q of , which may be obtained by subtracting Eqs.…”

“…The ultimate equilibrium concentration X eq corresponds to the concentration of the diluted solution when the solution is brought to equilibrium adiabatically. The estimation of X eq is explained in previous works (Gutiérrez-Urueta et al, 2011;Ventas et al, 2010).…”

“…Venegas et al (2004Venegas et al ( , 2005 and Arzoz et al (2005) The literature review about recent publications in the field of adiabatic absorption using aqueous LiBr or lithium-based liquid absorbents is presented by Gutiérrez-Urueta et al (2011). This includes the works reported by Warnakulasuriya and Worek (2006), Elperin et al (2007) and Wang et al (2007).…”

“…Both the solution coming from the generator m str0 ng and the recirculated solution m T flow inside the absorber forming droplets or fan sheets. The experimental setup configuration, the data acquisition system, the experimental uncertainty analysis and the experimental procedure were described in detail in other publication (Gutiérrez-Urueta et al, 2011). Table 1 shows the characteristics of all sensors used in the experimental facility.…”
