Résumé

This paper presents the first results from field-testing a novel solar heat driven off-grid medical refrigerator. The refrigerator is cooled by a miniature adsorption cycle, designed to run without any electricity. It is powered by hot water heated by a standard solar thermal collector, in contrast to other solar off-grid adsorption refrigerators. Water is used as the refrigerant. Firstly, the configuration of the Coolar adsorption refrigerator is introduced and then results from the first autonomous test are discussed, followed by an outlook on future steps. The refrigerator compartment temperature needs to stay within 2 to 8 °C at ambient temperatures of up to 32°C to satisfy the World Health Organization’s (WHO) requirements for off-grid vaccine refrigerators in temperate climates. This goal has not been fully achieved. However, easy to implement measures for improvement were identified and will be conducted to ensure sufficient performance of new prototypes ahead of the subsequent field tests.
