Abstract (en)
A refrigeration system (1) comprising a primary refrigeration circuit (2) that contains carbon dioxide and is provided with a compressor device (3), a primary cooling device (4), which is designed to perform a first cooling of the carbon dioxide leaving said compressor device (3), an expansion device (5) to expand the carbon dioxide and a heat-exchanger device (6) which accumulates heat in the expanded carbon dioxide supplied by the expansion device (5), and a secondary cooling device (10) which performs a second cooling of the carbon dioxide leaving the primary cooling device (4) to cause a further drop in the temperature of the carbon dioxide from said second temperature (t2) to a third temperature (t3), lower than said second temperature (t2), before the carbon dioxide is supplied to the expansion device (5).
