| Popis: | In this paper, an investigation of aqua-ammonia solar absorption refrigeration system for domestic use is presented. The refrigeration system investigated here is a conventional aqua-ammonia absorption refrigeration system powered by solar heater. The solar heater used is a stationary, hyperbolic sprial solar concentrator equipped with a glass tube for convection loss suppression. A generator temperature as high as 140°C is reached. The lowest temperature reached in evaporator is 2°C, with an additional external heating Source. The various parameters affected the cycle performance and cooling ratio, such as, the generator temperature, evaporator temperature, collector performance and condenser temperature are presented. For fixed initial conditions, higher generator temperature and lower condenser temperature increases the coefficient of performance and improves the operation of the system. |
