Premier camion frigorifique utilisant un frigorigène naturel

Sainsbury a récemment annoncé avoir mis à l'essai le premier camion frigorifique de transport de denrées réfrigérées et congelées, refroidi par un frigorigène naturel.
British supermarket giant, Sainsbury’s, has announced trials of the world’s first naturally refrigerated delivery truck for frozen and chilled goods, hoping to cut its carbon footprint by up to 10 000 tonnes a year.

The company announced that it teamed up with natural refrigeration-technology specialist Carrier Transicold for a two-year trial of its NaturaLINE HFC-free refrigeration system in a work refrigerated trailer.
NaturaLINE was initially developed for deep-sea refrigerated containers and uses two stages of CO2 compression with a variable speed drive and a unique cylinder-uploading capability allowing the compressor to save energy in light-load conditions.
