Abstract
Conservation of useful form of energy, i.e. electricity to be used in the production sector rather than consumption sector is becoming a priority in the KSA (Kingdom of Saudi Arabia). One of the consumption sectors which utilize a large amount of electrical energy is the air-conditioning and refrigeration sector. Improving the performance of refrigeration and air-conditioning systems and utilizing solar energy in powering such systems will contribute to significant conservation of electrical energy in the kingdom of Saudi-Arabia. Hence, the objective of the present study is to improve the performance of intermittent solar absorption refrigeration system. To achieve this objective, the design of a conventional intermittent system has been modified by introducing an economizer into the system. The analysis of the modified design system indicated an increase of 20% in the coefficient of performance of the system.
