EXPERIMENTAL RESULTS OF AN ADIABATIC SINGLE. EFFECT LiBr-H2O ABSORPTION FACILITY

G. Gutierrez*, P. Rodriguez, A. Lecuona, M. Venegas, J. Nogueira Universidad Carlos III de Madrid (UC3M). Departamento de Ingenieria Termica y de Fluidos. Avda.Universidad 30, 28911 Leganes, Madrid, Spain * Corresponding Author, glgutier@ing. uc3m. es Abstract An experimental facility applying the concept of adiabatic absorption has been designed and built in Universidad Carlos III de […]

The basic absorption model

Fig. 2 represents the thermodynamic states of the ideal simple effect absorption cycle, assuming mechanical, thermal and chemical equilibrium and assuming energy degradation exclusively concentrated on expansion valves. Steady state mass and energy balance in components yield the following equations: Evaporator (no superheating): Qm= m ref, K – h1); h1 = К (2) m ref, […]

Experimental setup

Two different sets of experiments were carried out to prove the advancements on the distribution system. 1. The objective of the first test is to determine the optimal size and number of discharge points distributed along the plastic tube. The optimized tube will serve the LD flow rate required by the application and ensure fairly […]

Basic absorption model vs. experimental results. Factors affecting the facility performance

Fig. 3 illustrates the comparison of experimental performance parameters with those obtained through the basic model, Eqs. (14) and (15), for 220 test points. The differences observed help identifying the influence of components performance, serving as a diagnosis. In the following, the causes of deviation from the ideal conditions are explained, evaluated and included in […]

Analysis of the results

The first set of experimental data for the distribution tube was analyzed by the factorial design analysis using MINITAB version 15. Factorial design analysis is a statistical method in which every level of one factor is tested in combination with every level of another factor. In general, in a factorial analysis, all possible combinations of […]

FIRST RESULTS OF A SOLAR-THERMAL LIQUID-. DESICCANT AIR CONDITIONING CONCEPT

B. M. Jones* and S. J. Harrison Department of Mechanical and Materials Engineering, Queen’s University, K7L 3N6, Kingston, Canada * Corresponding Author, jones@me. queensu. ca Abstract A thermal low-flow liquid-desiccant air handling machine was procured, installed, and field tested. The goal of the present investigation is to evaluate the field performance of the machine and […]
