Description

The utility model relates to railway transport and, more specifically, to the integrated equipment of passenger cars with jointly functioning heating, ventilation and air conditioning systems, ensuring the creation and maintenance of comfortable conditions for each passenger in each compartment of the car.

Known air conditioning system for a passenger railway carriage (patent RU No. 2169090, publ. 06/20/2001, IPC B61D 27/00), which contains an air-conditioned air supply fan, an air distribution duct, air-dispersed air supply panels in the service room and all compartments, thermoelectric generators cold or heat working autonomously. One of the generators is connected to the pressure and drain pipelines of the liquid heat sink system, a pump with coolant circulation pipelines and through a heat transfer pump is connected to heat exchangers located on the suction and discharge air channels of the central electric fan and is installed above the vestibule to provide the first stage of centralized cooling or heating of the air entering the carriage and compartment. The second generator is installed under the car to provide the second stage of cooling or heating of air in the car and is connected via a pump to compartment closers, consisting of heat exchangers and fans mounted in the office building and passenger compartments. Closers heat exchangers are connected to a parallel or serial hydraulic system for pumping coolant. Closers fans provide circulation of the cooled air in a compartment of the car.

Known air conditioning system for a passenger car (patent RU No. 37343, publ. 04/20/2004, IPC B61D 27/00), containing a ventilation unit and two refrigeration machines, one of which is combined with a ventilation unit and through its ducts provides the first stage of centralized cooling ( heating) of air in the car and is located on the roof and in the roof space of the car, and the second is connected by heat carrier lines with heat exchangers installed in each compartment of the car, characterized in that both olodilnye compression machine formed, wherein the second block is formed as a unit mounted on the carriage amortized over revolving platform.

Known climate control passenger car (patent RU No. 56302, publ. 09/10/2006, IPC B61D 27/00), which contains a heating system with a boiler and heaters located in each compartment, air conditioning unit located in the car space. Under the floor of the car body, discharge and recirculation channels are laid. From the air conditioning unit, air is supplied through the discharge channel to each compartment of the car through air ducts located along the side wall of the car, flowing through the air heaters, and exits through the lower exhaust windows or upper. Fresh air is supplied through the intake windows in the upper part of the car body.

A known air conditioning system for a passenger car (patent RU No. 87674, publ. 20.10.2009, IPC B61D 27/00, B60 N / 00), which, being the closest analogue, is taken as a prototype. The system comprises a monoblock air conditioner located in the roof space of the carriage with at least one refrigerating machine, with suction pipes for external and recirculated air and with treated air pipes in two parallel ducts laid along the carriage, between which there are purchased air supply units, each the purchase air supply unit is made in the form of a mixing chamber communicating through the inlet pipes with each of the air ducts and through the outlet pipe with channels for odachi air in the compartment and the passenger seats, wherein each inlet pipe of each node set controlled valve.

The disadvantage of this air conditioning system for a passenger car, as well as the above analogues, is the impossibility of creating autonomous comfortable conditions (microclimate) in a separate compartment of a passenger car, regardless of the microclimate in other coupes of the car.

The purpose of the proposed utility model is to create autonomous climatic conditions of increased comfort for each compartment of a passenger car, taking into account the needs of its passengers.

This goal is achieved by the fact that in the utility model, a two-channel ventilation and air conditioning system of a compartment (13) of a passenger car (see FIG. 1 and FIG. 2) is used, equipped with devices (5) for controlling the flow and air temperature in each compartment, air conditioning ( 1), which supplies air to the ducts (2) and (3), respectively, with a constant temperature t ₁ and t ₂ for each of them, while the temperature is set by the climatic parameters of the external environment. In addition, the system contains temperature sensors (10) in the compartment (13), modules of a wireless self-organizing computer network (MBSWS) (7, 8, 9), a central processor (11), shutters (4) with actuators (6), a mixing chamber (12), as well as a remote control (14) with a temperature indicator (15) and control buttons (16) in each compartment (13).

MBSWS is a "system on a chip" containing a transceiver with an antenna, a processor with memory, analog-to-digital converters, digital-to-analog converters, electronic keys and a power source (not shown conventionally in Fig. 1).

Two-channel ventilation and air conditioning coupe passenger car works as follows.

The passenger in the compartment sets from the control panel (14) the temperature he needs, which is displayed on the screen (15) using the buttons (16) (see figure 2).

In stand-alone mode, the MVSVS (8), without involving the computing resources of the local network of the car, controls the temperature in the compartment (13) according to a limited set of rules. MBSWS (8) cyclically interrogates temperature sensors (10) and obtains information about the temperature set by the passenger or the actual temperature in the compartment (13), compares it with the planned temperature corresponding to the optimal seasonal temperature regime and generates a control action via MBSWS (7) on the drives (6) ), controlling the position of the dampers (4), providing the necessary air supply from the air ducts (1) and (2) to the mixing chamber (12).

In the event that a limited set of rules governing the autonomous operation of MBSBCs is exceeded (8), the central processor of the car is connected to its local network, which is connected to temperature sensors (10) in each compartment (13) of the car through MBSVS (9).

If the compartment freely flaps (4) are in the closed position and air in the compartment (13) does not enter.

If in a neighboring compartment the passenger sets a temperature different from that set in the compartment under consideration (13), the central processor (11) analyzes the information and transmits it via MBSWS (9) and MBSWS (7) to flow and temperature control devices (5) as follows so that the air flow and temperature in the compartment under consideration (13) does not change.

The proposed utility model can significantly increase passenger comfort.
