Description

The claimed invention relates to air conditioning devices for a passenger carriage, primarily for transporting a special contingent.

A known ventilation system of a compartment of a passenger car (RF patent for utility model No. 97317, IPC B61D 27/00), which is part of a two-channel ventilation and air conditioning system, comprising an air preparation unit, air supply channels, air intake channels and a recirculation channel. In this analogue, the outputs of the air supply and intake channels are located on the walls of the compartment in the space between the end surfaces of the berths and, accordingly, the window and the door. This is unacceptable for the conditions of transportation of the special contingent, to which there is an increased requirement of vandal resistance and safety in the cramped conditions of transport.

A wagon for the special contingent is known (certificate of the Russian Federation for utility model No. 40971, IPC B61D 1/00), containing a passenger room with a ventilation system, connected by a corridor with office rooms. At the same time, air conditioners are installed only in the guard compartment, the remaining rooms do not have a climate support system, which does not meet the requirements of regulatory documents.

The ventilation car ventilation system was adopted as a prototype (RF patent for utility model No. 77231, IPC B61D 27/00). This system comprises an air blower and a first channel for supplying fresh air to one compartment of the compartment and a second channel for supplying fresh air to the second compartment of the compartment connected thereto located under the car roof.

In this prototype, airflow is supplied in a compartment. In this case, air-venting devices or openings should be provided. This decision is unacceptable for the conditions of transportation of the special contingent, to which there is an increased requirement of vandal resistance and safety in cramped conditions of transport. In addition, the presence of air ducts under the roof of the car reduces the usable volume for accommodating the special contingent.

The objective of the proposal is:

- compliance with vandal resistance requirements for a passenger carriage;

- ensuring increased passenger capacity of the car while maintaining a high rate of air exchange in passenger rooms.

For this, the car is equipped with an air conditioning system containing at least one air preparation unit (supercharger), connected to it and located inside the car, at least one supply air supply channel to the first group of rooms and at least one channel supply air supply to the second group of rooms.

What is new is that the air conditioning system is equipped with at least one recirculation air intake channel from the first group of rooms connected to at least one air preparation unit and located inside the car. New is the fact that the air conditioning system is equipped with an exhaust system for the release of air from the car, consisting of deflectors outside the car body and channels with exhaust openings inside the body. In this case, the second group of rooms is connected by a corridor over which at least one of the above-mentioned supply air supply channels to these rooms is located.

In addition, the supply air supply channels are provided with at least one hole from the side of the premises and (or) the corridor, and the corridor contains a decorative partition that sets the direction of air movement.

The technical result is expressed in the following.

The connection of the second group of rooms with a corridor and the location above it of the supply air supply channel to the second group of rooms ensures the supply of fresh air directly to the second group of rooms, thereby achieving the vandal resistance of a passenger car when transporting special contingent there. In addition, this increases the useful volume of the car to accommodate the special contingent, which increases its passenger capacity.

The presence of at least one recirculation air intake channel from the first group of rooms, connected to at least one air preparation unit, and an air exhaust system ensures acceptable air velocities in the car’s premises, as a result of which high air exchange rates are maintained under conditions of increased passenger capacity of the premises.

In addition, the presence of openings from the premises in the supply air supply channels provides ventilation by mixing, which involves large volumes of air in the carriage in the flow. As a result, the volume of the air stream increases, while its speed decreases the more, the further it penetrates into the room. The holes can be unregulated or made in the form of adjustable diffusers.

The accompanying drawings depict:

FIG. 1 - air conditioning system of a passenger car, general view;

FIG. 2 is a section A-A in FIG. 1;

FIG. 3 - section BB in figure 1;

FIG. 4 - air exhaust system, section BB in FIG. one.

The air direction in FIG. 3 is shown by arrows.

The air conditioning system of a passenger carriage comprises an air preparation unit 1 (supercharger), a supply air supply channel 2 to the first group of rooms connected to it and located inside the car, a supply air supply channel 3 to the second group of rooms, a recirculation air intake channel 4 from the first group of rooms connected to the air preparation unit 1 and located inside the car, an air exhaust system consisting of deflectors 5 (Fig. 4) outside the car body and channels 6 with exhaust openings three car bodies. The second group of rooms is connected by a corridor 7 (Fig. 1), above which there is a channel 3 for supplying fresh air to the second group of rooms. The channels 2, 3 are provided with at least one hole 8 (Fig. 3) from the side of the premises and (or) the corridor 7. The corridor 7 contains a decorative partition 9 (Fig. 3) that defines the direction of air movement.

Under the action of a fan (not shown) installed in the air preparation unit 1, air outside the car enters the supply air ducts 2, 3 of the first and second groups of rooms. From channel 2, through the openings, air enters the premises of the first group. From channel 3, through the openings, air enters a common channel, which forms a corridor 7, and then into the rooms of the second group, enveloping a decorative partition 9 that sets the direction of air movement. Through the channel 4 of the intake of recirculated air, the air flows back into the unit 1, without mixing with the air of the second group of rooms. This eliminates the spread of the microbiological danger of diseases. In addition, air is drawn from the premises by an air exhaust system consisting of deflectors 5 and channels 6.
