Utilization of Solar Water Heaters In Cooling System

Abstract

Studying the absorption refrigeration system under modifications has been conducted in the current research. The system has been connected to solar heater to provide hot water instead of the electrical heater in the system. Another contribution expressed in manual condenser cooling was also conducted to the system in order to enhance the efficiency at high temperature environment. The system showed good stability with the coupling of the two enhancements (manual cooling and solar heating) comparing with original electrical heater. The enhancements were represented in terms of COPs and temperature differences. Three hot water temperatures depending on the weather were used under various refrigeration loads. Boiler temperatures of 80, 90 and 95OC were used and the system scored the maximum COP of ~0.48 and temperature difference of ~16OC under high refrigeration loading and high boiler temperature. These results revealed that the coupling of solar energy with manual cooling were effective and promising approaches towards economical, clean and environmentally friendly operating procedure that can be applied practically to the system.
