Abstract
In an absorption refrigerating apparatus (18) operated by a fuel in gas or liquid state the condenser (50) is cooled by an air flow generated by a fan (82). The fan is driven by a heat operated motor consisting of an endless wire loop formed (84) of a shape memory alloy which gets its operating heat from the exhaust gas from the fuel.
