Abstract
When using systems that use the principle of absorption for the production of cold there is a great delay between the starting of the installation and the production of cold. This delay is due to the necessary time for the production of vapour.According to the invention a storing device of cooling liquid under pressure is proposed that is used instead of the vapours produced by a boiler (1) when starting the installation. This storing is done in a receiver (4) commanded by two valves, one called upstream valve (3) and the other called downstream valve (5).According to the invention the method consists in storing cooling liquid under pressure in a receiver and using this liquid under pressure when starting the installation.
