Description

[Detailed description of the invention] [Industrial application field] This invention includes an intake port for taking in air inside the towing vehicle and outside air, a heat exchanger, and an outlet for the heated air. Moreover, regarding a heating system for a railway vehicle that heats the interior of the train using a heater installed in the above-mentioned traction vehicle, it is particularly suitable for application to a heating system for a diesel vehicle and an auxiliary vehicle towed by the diesel vehicle. be.

[Summary of the idea]

This idea uses a duct for introducing cabin air into the heater installed in the towing vehicle, and a duct for supplying warm air from the heater to the accompanying vehicle being towed by the towing vehicle. By arranging the damper, the pressure and temperature inside the two vehicles can be maintained uniformly at all times.

[Conventional technology]

As a conventional technique, for example, as shown in Japanese Utility Model Publication No. 56-49803, there is a technique in which a heater is provided under the floor of a diesel vehicle to heat the interior of the diesel vehicle.

In addition, as shown in Japanese Utility Model Application No. 58-41607, a heater is specially installed on the roof of the passenger car, which is an accompanying vehicle, and warm air is sent through a duct to the driver's cabin of the locomotive, which is the traction vehicle. There is something like this.

[Problem that the invention attempts to solve]

However, in the example disclosed in Japanese Utility Model Publication No. 56-49803, the heater only heats the interior of the vehicle in which the heater is installed, and there is no mention of means for heating an accompanying vehicle with the heater.

Furthermore, in the example disclosed in Japanese Utility Model Application Publication No. 58-41607, a heater is specially installed in the accompanying vehicle, and the operator's cabin, which is only a part of the towing vehicle, is also heated by this heater. The interior of the accompanying vehicle and the driver's cabin are simply communicated through a duct.

By the way, since a towing vehicle is equipped with an engine for driving the vehicle, if this engine is a diesel engine, for example, as shown in the first example above, the cooling water heated by this engine may be used to save energy. The heater used is likely to be installed on the towing vehicle. Furthermore, based on the capacity of the heater, it is often attempted to heat not only the towing vehicle equipped with the heater, but also the accompanying vehicle.

In this case, since the interior volumes of the above two vehicles are generally almost equal, it is difficult to ensure uniform air pressure and temperature inside the vehicle and provide comfortable heating by simply connecting the interiors of the two vehicles with a duct. It is.

In view of the above-mentioned points, the present invention provides a heating system for a railway vehicle that is capable of always providing comfortable heating even when the towing vehicle and the accompanying vehicle are simultaneously heated by a heater installed in the towing vehicle. be.

[Means for solving problems]

The present invention is equipped with an intake port for taking in the interior air of the towing vehicle and outside air, a heat exchanger, and an outlet for the heated air, and is operated by a heater installed in the towing vehicle. In a heating system for a railway vehicle that heats the interior of a train, a heating duct piped into the interior of an auxiliary vehicle towed by the traction vehicle is connected to a flexible duct installed between the traction vehicle and the auxiliary vehicle. A heating duct piped into the interior of the vehicle and the flexible duct are connected at one end to the outlet and the other end to the other end of the branched duct, and the flexible duct is connected to the inlet for air inside the vehicle. A heating system for a railway vehicle was constructed by disposing a damper for adjusting air volume in the connected duct for taking in air inside the train and the above-mentioned flexible duct.

[Effect]

Therefore, it is possible to maintain the interior pressure of the towed vehicle at a positive pressure at all times by operating the damper provided in the duct for taking in the interior air. Further, by operating a damper disposed in the flexible duct, it is possible to prevent a difference in air pressure and temperature inside the vehicle between the towing vehicle and the accompanying vehicle. In other words, by operating the two dampers in conjunction with each other, the interior air pressure of the two vehicles can be maintained at a uniform positive pressure, the interior temperature can be kept uniform, and comfortable heating can be achieved.

〔Example〕

Hereinafter, an embodiment in which the present invention is applied to heating a diesel vehicle and an accompanying vehicle towed by the diesel vehicle will be described with reference to FIGS. 1 to 3.

As shown in Figure 1, diesel vehicle train formations generally have a leading and a trailing traction vehicle (hereinafter referred to as
(abbreviated as "M vehicle"), and two accompanying vehicles (hereinafter abbreviated as "T vehicle") between the above two M vehicles.
is often placed. In this case, the adjacent M vehicle and T vehicle are connected by a flexible duct 1, and the interiors of both vehicles are communicated with each other to form one unit, and the interior of the vehicle is heated.

As shown in FIG. 2, a heater 2 is provided in the ceiling of the vehicle M, and heated and cooled water from the diesel engine is circulated through a heat exchanger 3 disposed within the heater 2. In addition, for piping to heat exchanger 3,
is provided, and when this pot 4 is closed, the heat exchanger 3 is cut off from the heat source.

The outside air intakes 5 with louvers belonging to the heater 2 are arranged on the left and right sides of the vehicle M, respectively, as shown in FIG. In addition, the two left and right interior air intakes 8 provided on the rear side of the heater 2 have interior air intake ducts 9 connected to the louvered openings 9a provided in the ceiling of the M vehicle, as shown in FIG. are connected to each other, and a first damper 10 whose opening/closing degree can be freely set is provided at the end of the duct 9 on the intake port 8 side.

Next, in both M and T vehicles, heating ducts 1 are installed on the left and right sides near the floor 11 inside the vehicle and along the longitudinal direction of the vehicle.
A plurality of hot air outlets 15 with louvers provided in the duct 12 open below the seat 16. Further, the duct 12 of the T vehicle is connected to one end 1a of the flexible duct 1 after the partition wall is raised as shown in FIG. 3, and the left and right sides are combined.

Next, a branch duct 18 is connected to the heated air outlet 17 arranged on the rear side of the heater 2 in order to take out the heated air from the heater 2. In addition, the ends of the rising portions 12a of the left and right heating ducts 12 arranged in the vehicle M and the other end 1 of the flexible duct 1 are arranged in the partition wall of this vehicle.
b are respectively connected to the other branched ends of the branch duct 18. The other end 1b of the flexible duct 1 is provided with a second damper 19 whose opening/closing degree can be freely set.

As a result of the heater 2 being installed in the ceiling of the vehicle as described above, the configuration of the ducts 9, 12, 18, etc. is simplified, and the space inside the vehicle and under the floor can be used effectively. Furthermore, the heater 2 can also be used as a ventilation system in the car by closing the heater 4.

Next, to describe the operation of the vehicle heating system configured as above, when the cooktop 4 shown in FIG. 2 is opened,
Cooling water heated by the diesel engine is transferred to heat exchanger 3
circulate through. Therefore, the air that is sent to the heat exchanger 3 by the blower installed in the heater 2 and that has passed through the heat exchanger 3 is heated.
By sending this air into the car as described below, the inside of the car can be heated.

In this case, if the air inside the car is introduced from the intake port 8 along with the outside air introduced from the intake port 5, and the ratio of both is adjusted appropriately and heated by the heat exchanger 3, the air can be heated even in extremely cold weather. , the temperature inside the vehicle can be kept within a desired range. Furthermore, since a desired amount of outside air can be sent into the car interior, there is no fear that the air inside the car will become contaminated and cause discomfort to the passengers.

Next, the air heated through the heat exchanger 3 flows out from the outlet 17 shown in FIG. 3 into the branch duct 18 due to the wind pressure created by the blower,
After being distributed to the heating ducts 12 of both T vehicles and flowing in, the hot air is blown out from the hot air outlet 15 into the interior of each vehicle to heat the interior of the vehicle.

In this case, a first damper 10 is provided at the end of the in-vehicle air intake duct 9, and a second damper 19 is provided at the other end 1b of the flexible duct 1, and both can be freely opened and closed. Since the pressure can be set, it is easy to maintain the internal pressure of both M and T vehicles at positive pressure at all times.

That is, each cross-sectional position is distinguished by a suffix, with the air flow rate being V (m ³ /h), V _F : Outside air passing through the intake port 5 V _R : Air inside the vehicle passing through the first damper 10 V _M : M vehicle Air flowing into the heating duct 12 _VT : Air passing through the second damper 19 V _EM : Air passing through the exhaust port 22 provided on the gable side of the M car V _ET : Air flowing through the exhaust port 22 provided on the gable side of the T car Considering the air passing through the exhaust port 22, etc., in a steady state, V _F +V _R =V _M +V _T ...(1) V _M =V _R +V _ET ...(2) V _T =V _ET ...( The relationship 3) holds true.

Therefore, from equation (2), V _M > V _R ...(4) If equations (2) and (3) are substituted into (1) and V _M and V _T are eliminated, V _F = V _EM + V _ET ...(5) Here, due to the presence of dampers 10 and 19, V _T and V _R
is a variable, so if the internal pressure of the T vehicle fluctuates for some reason, the second damper 19 can be operated to increase or decrease V _T to return the internal pressure to a predetermined positive pressure.

Furthermore, if the internal pressure of the M vehicle fluctuates for some reason, the first damper 10 may be operated to increase or decrease V _R to return the internal pressure to a predetermined positive pressure.
In this case, if the relationship of equation (4) exists, even if the above-mentioned interior pressure becomes negative, the interior pressure can be returned to the desired positive pressure.

Since the interior of the vehicle becomes a load, problems such as outside air with snow being sucked into the interior of the vehicle through the exhaust port 22 or gaps between doors do not occur. Also, as a result, there is no inconvenience such as the door freezing. Furthermore, as is clear from equation (5), the outside air that needs to be newly supplied to the inside of the car is supplied to the intake port 5.
Incorporated from.

[Effect of idea]

Since the present invention has the above-described configuration, the accompanying vehicle can also be heated by the heater installed in the towing vehicle. Moreover, the device configuration can be extremely simple.

Furthermore, in the device of the present invention, a portion of the air inside the towed vehicle is returned to the heater to save energy, but this does not place a load on the interior air pressure of the towed vehicle.

In addition, the device of this invention uses a simple air volume adjustment mechanism to equalize the interior temperature of the towing vehicle and accompanying vehicle.
Moreover, the air pressure inside the vehicle can be maintained at a desired positive pressure.
