FIELD: gas industry.
SUBSTANCE: device for recuperation of cold units of LNG (liquefied natural gas) used as fuel in vehicles, including: the first heat exchanger (1) placed on the tractor (10) of the vehicle between the LNG tank (14) and the gasification circuit (12, 18) and heating the LNG, while the specified LNG is sent to the engine (13) of the vehicle, the second heat exchanger (2) located inside the cooled cabin (11) of the trailer or semi-trailer (20) of the vehicle, a closed intermediate circuit (15), in which the heat transfer fluid, including a device (3) for moving the heat transfer fluid, systems (4, 5) for connecting and disconnecting pipelines of the intermediate circuit (15), which are installed on the tractor (10), and pipelines of the same intermediate circuit (15) installed on a trailer or semi-trailer (20), and a device for storing and reintegrating the heat transfer fluid in the intermediate circuit (15) and for maintaining fluid-t coolant at a certain pressure value in the specified intermediate circuit (15).
EFFECT: invention allows the use of LNG refrigeration units that would otherwise be dispersed to the environment when LNG is used as a fuel in refrigeration vehicles, thereby achieving corresponding fuel savings and a corresponding reduction in pollutant and carbon dioxide emissions to the atmosphere.
