Parasol with incorporated atmosphere refrigeration system comprises central tube support containing charge able to sublimate at ambient temperature and generate cold through holes in support

摘要

The parasol comprises a central tube support (2) having a movable sliding stiffener system (11) able to open or close the parasol. Incorporated in the support is a charge with a composition able to sublime at ambient temperature by an endothermic mechanism, i.e. generating cold, through holes (13,15).
