Example of cooling of the heat exchange ventilation system

2 is a configuration diagram in which only the cooling module is installed. Referring to FIG. 2, the train does not include the waste heat recovery ventilation module, and is formed in a state in which only the cooling module 110 is installed, thereby lowering an internal temperature by cooling the air inside the train.

In this case, the cooling module 110 includes an evaporator 111, a compressor 113, a condenser 115, and an expansion valve 117. The evaporator 111 allows the refrigerant to phase change from a liquid state to a gaseous state, at the same time take away heat from the surroundings, and cool the air around the evaporator 111.

At this time, the first ventilation pipe 120 is formed to discharge the air in the train interior space to the outside, the second ventilation pipe 122 is formed to introduce the outside air into the train interior space.

The air discharged through the first ventilation pipe 120 is cold, but the indoor air is contaminated. In addition, the air introduced through the second ventilation pipe 122 is hot, but clean air.

At this time, the air inside the train can be kept clean by discharging the contaminated air to the outside through the first ventilation pipe 120 and the second ventilation pipe 122 and introducing clean air into the train.

If only the air in the train interior space is simply ventilated through the first ventilation pipe 120 and the second ventilation pipe 122, the air inside the cold train is discharged to the outside, and the hot outside air flows in. This can reduce the cooling efficiency of the train.

Therefore, an embodiment of the present invention includes a waste heat recovery ventilation module 130 that recovers waste heat in order to ventilate the air inside the train and improve the cooling efficiency of the train.

The interior of the waste heat recovery ventilation module 130 may be used by applying the total heat exchanger 132 as shown in FIG. 4, and may be used by applying the heat pipe heat exchanger 134 as shown in FIG. 5. .

Referring to FIG. 13, unlike the sixth and seventh embodiments, the eighth embodiment does not connect the first heating pipe 240 or the second heating pipe 250 to the waste heat recovery ventilation module 230. Can be formed. Accordingly, the internal air sucked through the air suction nozzle 254 may not be directly connected to the second ventilation pipe 222, but all may be transferred to the heater 214.

At this time, the air inside the train may be exchanged with the outside air through the waste heat recovery ventilation module 230 formed separately from the heating module 210 to ventilate the air inside the train. At this time, the air cooled in the air flowing in the train may be formed to discharge through the first ventilation pipe 220. Accordingly, the waste heat recovery ventilation module 230 may be formed in the ceiling of the train.

In addition, since the air introduced through the second ventilation pipe 222 is fresh outside air and heat exchanged with the first ventilation pipe 220, the air may be formed at a higher temperature than the air outside the train. It may be formed at a lower temperature than the air supplied from the nozzle 244.

At this time, the air introduced through the second ventilation pipe 222 is mixed with the air inside the train to ventilate the air inside the train to the outside clean air, the train through the first ventilation pipe 220 The polluted air inside can be discharged to the outside. In addition, the first ventilation pipe 220 and the second ventilation pipe 222 may further include a blower such as a fan to more effectively ventilate the air inside the train.

In addition, the waste heat recovery ventilation module 230 may be operated at a predetermined time interval by a control device (not shown), and the amount of ventilation may also be controllable. In addition, the above-described cooling module and heating module may be installed in both trains, and may be selectively used according to seasons or temperatures.

At this time, the cooling module and the heating module may be installed in parallel. Accordingly, the cooling air supply pipe during cooling may be used as the cooling air discharge pipe during heating, and the heating air discharge pipe during cooling may be used as the heating air supply pipe during heating.

On the other hand, Figure 14 shows a state in which the waste heat recovery ventilation module of the present invention is installed in the train. Referring to FIG. 14, it may be installed at an outer ceiling of the train, and the first blower 136 having the blower may be formed in a horizontal direction to forcibly discharge air in the train.

In addition, the second blower 138 may be formed in a direction perpendicular to the driving direction of the train so that external air may be introduced therein without a separate power unit during the driving. In addition, a heat exchanger 132a may be formed between the first blower 136 and the second blower 138 to allow ventilation and heat exchange at the same time.
