Abstract

The utility model relates to railway transport, in particular to isothermal vehicles. The technical problem to which the proposed utility model is aimed is to improve the layout of the equipment of the engine room in order to improve the convenience of maintenance, equipment repair, as well as increase the volume of the fuel tank. The technical result is achieved by the fact that in a refrigerator car containing an engine room equipped with a refrigeration unit, a diesel generator unit, a fuel tank, is located on one side of the car, while the fuel tank is mounted on the frame of the car under the floor of the engine room.

Description

The utility model relates to railway transport, in particular to isothermal vehicles.

A well-known autonomous refrigerator car (Osadchuk G.I., Farafonov E.S. Refrigeration equipment of cars and air conditioning. M .: Transport, 1974. P.223) containing a cargo room and two engine rooms located at the ends of the body. Each engine room has one diesel generator set, as well as refrigeration and heating systems.

Closest to the proposed utility model and selected as a prototype is an autonomous refrigerated wagon designed for the transport of perishable goods. The wagon has a cargo room and two engine rooms located at the ends of the body, each of which has a diesel generator unit and a refrigeration unit. The removable diesel-generator unit of the block type has a steel frame on which are mounted: a diesel connected to the generator, a heating installation, as well as a fuel tank (http://www.aswn.ru/design/freihtcars/izotermicheskie/refrigerated).

The disadvantage of this car is the irrational layout of refrigeration and diesel generator equipment, in which the equipment occupies a significant part of the engine room space, which complicates maintenance and repair.

The technical problem to which the proposed utility model is aimed is to improve the layout of the equipment of the engine room in order to improve the convenience of maintenance, equipment repair, as well as increase the volume of the fuel tank.

The technical result is achieved by the fact that in a refrigerator car containing an engine room equipped with a refrigeration unit, a diesel generator unit, a fuel tank, is located on one side of the car, while the fuel tank is mounted on the frame of the car under the floor of the engine room.

The utility model is illustrated by drawings, where:

in FIG. 1 shows a general view of the engine room of a refrigerator car;

in FIG. 2 - layout of the equipment of the engine room;

in FIG. 3 is a section AA in FIG. 2.

The refrigerator car 1 contains an engine room 2, equipped with a refrigeration-heating installation (hereinafter - HOU) 3, made in the form of a single unit with a diesel unit and an electric generator.

HOU 3 is located on the insulated partition 4, dividing the engine room 2 and the cargo room of the car 1.

To supply the diesel generator set with fuel, a fuel tank 5 is placed on the frame of the car 6 under the floor 7 of the engine room 2.

Due to the fact that in the proposed refrigerator car the engine room is located on one side of the car, it is necessary to install a set of refrigeration and power equipment with greater productivity compared to the prototype. For the operation of such equipment, a large-capacity fuel storage tank is required, which occupies a large volume of the engine room, which complicates the mutual arrangement of power and refrigeration equipment, and also reduces the comfort of equipment maintenance and repair.

Placing the fuel tank on the car frame under the engine room floor eliminates the problem.

HOU 3 has an electronic control system 8 located on the partition 4, and for remote monitoring and control of the operation of special equipment and temperature conditions in the cargo room via a wireless communication channel (satellite or cellular) - a remote control and control system 9 is also located on the partition four.

Refrigerated car works as follows.

The cargo compartment of wagon 1 is insulated and equipped with an air duct located under the ceiling, as well as floor grilles for circulating air flows around the transported cargo.

HOU 3, located on the partition 4 of the engine room 2, pumps cold air into the cargo room of the car 1, evenly distributing it along the entire length through the duct. Air washes the load, returns to the vertical channel between the load and the partition 4 of the engine room 2 of the car under the floor grilles, is sucked in by the fans and, passing through the air cooler, is again pumped into the duct. Similarly, the circulation of warm air occurs during the heating of the car, while instead of the refrigeration unit, the heating devices of the HOU are switched on.

The remote monitoring and control system 9, consisting of an electronic wireless communication device and a set of sensors, is connected to the control system 8 of the CLE 3. The remote monitoring and control system 9 transmits to the operator, via a wireless communication channel, information about the current operating conditions of the CLE and the controlled parameters of the car (geolocation, temperature conditions in the cargo room, fuel level in the tank, door open signal, etc.), and also allows you to adjust the operating modes of the HOU 3, receiving control signals from the operator and transferring them to the control system 8.

Claims (1)

A refrigerator car comprising a machine room equipped with a refrigeration unit, a diesel generator unit, a fuel tank, characterized in that the engine room is located on one side of the car, and the fuel tank is mounted on the car frame under the floor of the engine room.
