Experimental Analysis and Thermodynamic Modeling of a Diffusion-Absorption Refrigerator
Experimental investigations and theoretical analysis of a commercial diffusion-absorption refrigerator are presented in this paper. During the tests, the temperature at 14 locations – at the inlet and outlet of every component of the machine – as well as the cabinet and ambient temperature is measured. The tests are repeated for various electric power inputs to the refrigerator. The steady-state cooling capacity of the machine and its coefficient of performance, COP, are evaluated. The experimental data is used to validate a theoretical simulation model of the machine developed using the flow-sheeting software HYSYS of AspenTech.
