“…The COP maximizing charge was related to a COP maximizing subcooling. Primal and Lundqvist (2005) had also optimized the charge of an R290 domestic water heat pump and found the corresponding subcooling to be 4e5 C. Poggi et al (2008) published a review about refrigerant charge issues in refrigeration systems. They also related COP maximizing refrigerant charges to an appropriate subcooling in the condenser.…”

“…The paper presents a very interesting series of results and conclusions about the possibilities for charge reduction and minimization of leakages in refrigeration equipment. The second one, Poggi et al (2008), because it presents a very complete review on the subject and an excellent discussion on all aspects related with charge reduction.…”

“…En el Sistema Internacional la capacidad de refrigeración se expresa normalmente en kW. Para el volumen de control que incluye el evaporador, los balances de masa y energía dan el calor transferido por unidad de masa de refrigerante donde n evaporació h  es la variación entálpica másica y m  es el flujo másico de refrigerante (Poggi et al, 2008).

Para ello se realizó el estudio experimental de las prestaciones de compresores herméticos a temperaturas ambientes de 35 y 38 °C y se compararon con las obtenidas según las condiciones de pruebas estándar ASHRAE y CECOMAF. Se emplearon compresores herméticos de tres fabricantes en los que se determinaron los parámetros termodinámicos citados a través de un calorímetro a fluido secundario y se realizó la prueba de marcha acelerada para conocer los desgastes mecánicos de los grupos constructivos. Los resultados evidencian que se pierde como promedio más del 10 % de la capacidad frigorífica y más de 7 % de eficiencia. La evaluación en banco de marcha acelerada mostró que ningún compresor manifiesta en sus partes desgaste mecánico intenso.

Efficiency and Cooling Capacity AbstractThe behavior of the cooling capacity and efficiency of hermetic compressors operating in tropical conditions is studied and the effect on the functioning of domestic refrigerators is evaluated. For this experimental study, the performance of hermetic compressors at ambient temperatures of 35 and 38 ° C was analyzed and compared with those obtained under the standard CECOMAF and ASHRAE test conditions. Hermetic compressors from three manufacturers were used, in which such thermodynamic parameters were determined through a secondary flow calorimeter and an accelerated run test to know the mechanical wear of the compressor components. The results show that, on the average, more than 10% of the cooling capacity and more than 7% efficiency of the hermetic compressors studied are lost. The assessment in accelerated run showed that none of the compressor components presented intense mechanical wear.
