RU53635U1 - VEHICLE WITH MONO-BLOCK CONSTRUCTION AIR CONDITIONER - Google Patents

Abstract

The utility model relates to railway transport and relates to air conditioning devices for monoblock construction of vehicles. The essence of the claimed technical solution lies in the fact that the air conditioner of a monoblock design is installed in a compartment located in the roof of the vehicle body and is equipped with a removable body cover made in the form of a fragment of the radius part of the vehicle body roof, copying its shape, and the cover is connected by a detachable connection through the straps clamping with the supporting surface of the compartment into a single power structure of the roof of the vehicle body. The technical result achieved by the utility model is to improve the following vehicle performance: - aerodynamic properties; - design; - manufacturability of the operation of the air conditioner.

Description

The utility model relates to railway transport and relates to air conditioning devices for monoblock construction of vehicles.

Inter-regional communication wagons with air conditioning units are known, described in the book by Yu.O. Faerstein, B. N. Kitaev, “Air conditioning in passenger cars,” Transport Publishing House, Moscow, 1984, pp. 144-149, section 6 , "Air conditioning units in passenger cars", Fig. 83. The air conditioning system of these cars consists of three main units: the compressor and condenser are located under the car body, and the evaporator is an air distributor, mounted in the air duct of the supply air conditioning system.

The undercar assembly of the air conditioning units has a significant drawback - the surface of the heat-exchange coil, blown by the outside air, is quickly covered with a thick coating of dirt, which worsens its heat transfer ability.

The main disadvantage of undercarriage compressor and condenser units is the presence of flange and threaded connections, which means the possibility of refrigerant leaks, as well as the deterioration of the heat transfer capacity of the walls of the coil of the heat exchanger blown by outside air.

A technical solution is known, protected by patent for invention N 2236967 according to application N 2002129229 dated 01.11.2002, IPC 7 В 61 D 27/00, В 60 Н 3/00, where the air conditioner body is embedded in the roof of the car body and has the maximum permissible value protrusions defined by the standard for the railway gauge.

The protruding part of the air conditioner body above the roof of the car creates additional resistance to movement and worsens the appearance (design) of the car, and smoke from the boiler’s flyarck contaminates the protruding part of the air conditioner. These comments relate to the shortcomings of the analogue.

For the prototype, a technical solution was made, protected by the certificate for utility model N 0006764 according to the application N 97104536/20 of 06.16.98 g, MPK6 B 61 D 27/00, in which the air conditioning unit is made in the form of a monoblock and is located in the under roof space.

The disadvantages of this air conditioning installation include the laborious installation and dismantling of the air conditioner monoblock in the under-roof space of a passenger car, as well as the difficulty of servicing its internal components during the operation of the cars.

The essence of the claimed technical solution lies in the fact that the air conditioner of a monoblock design is installed in a compartment located in the roof of the vehicle body and is equipped with a removable body cover made in the form of a fragment of the radius part of the vehicle body roof, copying its shape, and the cover is connected by a detachable connection through the straps clamping with the supporting surface of the compartment into a single power structure of the roof of the vehicle body.

The technical result achieved by the utility model is to improve the following vehicle performance:

- aerodynamic qualities;

- design;

- manufacturability of the operation of the air conditioner.

The essence of the utility model is illustrated by drawings, where:

figure 1 General view of the vehicle with air conditioning monoblock design;

figure 2 is a left view of a vehicle with air conditioning monoblock design;

figure 3 is a plan view of a vehicle with an air conditioner cover of a monoblock structure;

in Fig.4, the attachment point of the air conditioner cover on the vehicle.

The vehicle 1 (figure 1) is equipped with air conditioning 2 monoblock design with a cover 3 (figure 2) installed in the compartment of the roof of the body 4.

In the cover 3 there are intake windows 5 (FIG. 3) for blowing air conditioning condensers with air and a window 6 for discharging this air, as well as windows 7 for supplying fresh air to the vehicle interior. A seal is attached to the supporting surface 8 of the compartment (figure 4) of the roof of the vehicle body -

shock absorber 9. Along the contour of the compartment of the roof of the vehicle body are placed straps clamping 10 fastening the cover of the air conditioner.

The installation of the air conditioner 2 in one-piece construction in the vehicle 1 consists in joining the detachable elements for fastening the air conditioner cover and the body roof compartment and in sealing the supporting surface by means of a seal - shock absorber 9.

Thus, the claimed design of the air conditioner, compared with those discussed above in the present description allows you to:

- significantly reduce the complexity of installation and simplify the process of installing an air conditioner in a vehicle;

- to exclude the implementation in the roof of the vehicle and its side walls of special windows, louvre grilles and intermediate pipes for supplying external air to the air conditioner;

- to exclude the use in the vehicle ventilation system of intermediate air chambers, pipes and other transition elements between the hull structure of the vehicle and the air conditioner;

- significantly simplify access to the internal components of the air conditioner during its maintenance;

- to exclude from the vehicle a separate complex cover for loading the air conditioner.
