Description

Large-scale gas freight train driver's cabin refrigerating plant

Technical Field

The utility model relates to a gas freight train technical field specifically is a large-scale gas freight train driver's cabin refrigerating plant.

Background

At present, under the condition of long-distance driving of large-scale gas (LNG gas or compressed natural gas and the like) freight cars, a large amount of compressed combustible gas is required to be converted into a gaseous state from a liquid state through a pressure reducing device and then enters an engine for combustion. During the conversion of a large amount of combustible gas from liquid to gas, the condensed gas is discharged to the outside by absorbing the external heat. Under the condition that the discharged condensed gas is not released in time, the icing phenomenon is formed at the gas outlet pipe part of the filling body for storing the combustible compressed gas. Therefore, the connection part of the filling body and the air outlet pipe continuously generates the phenomenon of cold and hot alternation under the condition that the vehicle stops running, thereby reducing the service life and simultaneously having potential safety hazards.

Therefore, a large-scale gas truck cab refrigerating device is provided.
