Description

thermoelectric devices for air conditioning in her

installed in each compartment of the car.

The disadvantage of this system is that it has insufficiently high cooling capacity.

This is explained by the fact that the cooling capacity of this system is determined by the cooling capacity of its thermoelectric devices.

The objective of the present invention is to develop the design of the air conditioning system of a passenger car, which allows to increase the cooling capacity of this system without increasing electricity costs.

The problem is solved in that the known passenger car air conditioning system comprising ventilation means, a longitudinal air supply channel and thermoelectric air conditioning devices installed in a compartment and connected to a longitudinal air supply channel is provided with an indirectly evaporative air conditioning device, the input of which is connected to the means ventilation, the output of the main air stream is with a longitudinal air supply channel, and the output of the auxiliary air stream is connected with outdoor atmosphere.

The difference between the proposed air conditioning system

passenger car from the above known, closest to it, is to provide it with an indirect evaporative device for air conditioning, the inlet of which is connected to the ventilation means, the output of the main air stream - with a longitudinal air supply channel, and the output of the auxiliary air flow is connected to the outside the atmosphere. it is cooled and then into thermoelectric devices for

air conditioning installed in the compartment where it is re-cooled.

Thus, the technical result of the proposed system is to increase its cooling capacity without changing the electric power costs.

The proposed air conditioning system is illustrated by the drawings shown in FIG. 1-3.

In FIG. 1 shows a general view of the air conditioning system of a passenger car;

in FIG. 2 - indirect evaporation device in the context of dry channels;

in FIG. 3 - indirect evaporation device in the context of wet channels.

The air conditioning system of the passenger carriage comprises ventilation means 1, a longitudinal air supply channel 2 and thermoelectric air conditioning devices 3 installed in the compartment 4 and connected to the longitudinal air supply channel 2.

This system is equipped with an indirect evaporating device 5 for air conditioning, the inlet 6 of which is connected to the main ventilation means 1, the output 7 of the main air flow is connected to the longitudinal air supply channel 2, and the output 8 of the auxiliary air flow is connected with the external atmosphere, i.e. thermoelectric devices 3 for air conditioning are connected to the ventilation means 1 through an indirectly evaporating device 5 for air conditioning.

The main ventilation means 1 can be made in the form of one or more fans.

3 which has a package of plates 10 forming dry channels (see Fig. 2) for the main air flow and wet channels (see Fig. 3) for the auxiliary air flow. This device 5 has at least one transverse row located in the middle of the plate pack 10 and longitudinally placed in the dry and wet channels of the closed water containers 11, one of the longitudinal walls of which are formed by the plates 10. The closed containers 11 are interconnected via openings 12 for the supply of water made in the plates 10. The device 5 also has means (not shown in the drawings) for supplying and discharging water into these containers I. Position 13 indicates a pipe for removing the auxiliary air flow outside the car, and 14, plugs for removing the auxiliary air flow into the nozzle 13. The air conditioning system of the passenger car in this embodiment of the particular embodiment has a pipe 15 for supplying and discharging water to the hot junctions of thermoelectric devices 3 for air conditioning. The specified pipe 15 is connected with a pump 16 for supplying water and with a heat exchanger 17 for cooling the water. The pipe 13 can be equipped with a deflector 18. The air conditioning system of a passenger car works as follows. Fresh air enters the ventilation means 1 and is supplied by it to the indirect evaporation device 5. In this device, air passes through the dry channels (see Fig. 2) and through the moist channels (see Fig. 3), forming the main air flow and auxiliary. The auxiliary air flow passing through the wet channels along the walls of the plates 10 of capillary-porous material moistened with water by capillary wetting from closed containers 11, being moistened and taking away heat from the main air flow, enters through the wet channels, deflecting the plugs 14, into the outlet pipe 13 (see. Fig. 3), and from it into the outdoor atmosphere. The main air flow through dry channels cooled without changing 4 of its moisture content (see

FIG. 2) enters the longitudinal channel 2 for air supply. From it, this air enters the cold junctions of thermoelectric devices 3, passing through which it is additionally cooled and then enters compartment 4.

Through pipeline 15, water is pumped by pump 16 to heat exchanger 17, where it is cooled, and then to hot junctions of thermoelectric devices 3, cooling them.

For better air conditioning efficiency, air recirculation is used, while the air coming from the compartment into the corridor of the car is sucked in by ventilation means 1 and supplied to the indirect-evaporation device 5 for air conditioning.

Thus, the use of the proposed system

air conditioning of a passenger car allows to increase its cooling capacity without increasing electricity costs.
