The invention discloses a refrigerating device applied to a light rail train. Therefrigerating device comprises a box body, a main circulating pump and a fan are arranged in the box body, the surface of the box body is provided with an air outlet and an air inlet used for introducing cooling air into the box body, and a radiator group used for performing heat exchange on the cooling air is arranged in the box body; the radiator group is connected between the main circulating pump and a plurality of cooled objects of a target light rail train through a circulating pipeline, an expansion water tank used for keeping the pressure of the circulating pipeline constant is arranged on the circulating pipeline, a brake resistor used for conducting air cooling on cooling air is further arranged in the box body, and after the brake resistor is subjected to air cooling through the cooling air, cooling air is discharged through the air outlet. Obviously, by means of the refrigerating device, noise generated in the refrigerating and heat dissipation process of the multiple cooled objects on the target light rail train can be remarkably reduced, and the user experience of passengers taking the target light rail train is improved.
Description
technical field [0001] The invention relates to the technical field of light rail trains, in particular to a refrigeration device applied to light rail trains and a control method for the refrigeration device. Background technique [0002] Light rail trains are a kind of rail trains that are more common in our daily life, such as: low-floor modern trams, suspended monorails and tourist trains, etc. Among them, light rail trains have higher requirements for the miniaturization of load-carrying converters or traction motors, and in order to avoid the interference of light rail trains on the surrounding operating environment, there are strict regulations on the noise emitted by light rail trains. [0003] At present, there are usually a variety of cooled objects that require cooling and heat dissipation on light rail trains, such as: on-board converters, traction motors, and auxiliary converters. In the prior art, when cooling and dissipating heat from these cooled objects, a ...
