Description

Railway vehicle

The present invention relates to a railway vehicle equipped with an air conditioner, and the air conditioner is divided into a plurality of sections by a partition wall, and has an exhaust blower corresponding to each section.

Railcars are equipped with air conditioners to keep the temperature and humidity in the car comfortable. For example, when both the outside air temperature and the vehicle interior temperature are high, this air conditioner lowers the temperature of the air taken into the air conditioner from the vehicle interior and recirculates the conditioned air generated by removing the humidity into the vehicle interior. This reduces the temperature and humidity in the vehicle and realizes a comfortable vehicle environment.

In the process of generating conditioned air, the air conditioner discharges a part of the air taken in from the inside of the car and takes in fresh air from the outside of the car and returns it to the inside of the car to suppress an increase in the carbon dioxide concentration in the car. is doing. Patent Document 1 discloses a ventilation control system for a railway vehicle, which controls a damper of a ventilator and a ventilation blower based on a predicted ventilation amount calculated based on a predicted number of passengers calculated in advance. A technique for controlling a damper of a ventilator and a ventilating blower to correct the ventilation amount based on the difference between the necessary ventilation amount based on the actual number of passengers calculated and the predicted ventilation amount is shown.

Responsible for ventilation and temperature / humidity control. The other air conditioner 2b is responsible for ventilation and temperature / humidity control in the range from the guest room 76 to the entrance / exit 72b including the toilet 80.

Since the

air conditioners

2a and 2b have common components, the description of the air conditioner 2b will be omitted below, and only the configuration of the air conditioner 2a will be described. As shown in FIGS. 3 and 4, the air conditioner 2a includes a compressor 20a, an outdoor heat exchanger 21a, an outdoor fan 23a, an indoor heat exchanger 22a, an electric heater 25a, and an indoor fan that constitute a refrigeration cycle in which refrigerant circulates. 24a and an exhaust blower 29a for exhausting the air inside the vehicle to the outside of the vehicle. In addition, the component which the air conditioner 2b has is obtained by replacing “a” at the end of the reference numeral indicating each component of the air conditioner 2a with “b” (the air conditioner 2b shown in the lower right of FIG. 5). .

The air conditioner 2 a includes an air conditioning return port 26 a (FIG. 4) for taking in return air at a position corresponding to the duct return port 44 a (FIG. 2) provided on the ceiling of the railway vehicle 1, and the conditioned air duct 32 is provided with a conditioned air duct 32. An air conditioning conditioned air supply port 28a (FIG. 4) is provided at a position corresponding to the air supply port 42a (FIG. 2). The air conditioning return port 26a is provided with an in-vehicle temperature sensor 91a (FIG. 4) for detecting the temperature in the vehicle. The air conditioner 2b also includes the same air conditioning arrangement configuration and sensors as described above.

In addition, the air conditioner 2a has an air conditioning exhaust intake 30a (FIG. 4) at a position corresponding to the duct exhaust port 37a (FIG. 2) of the exhaust duct 36a (FIGS. 2 and 3) provided on the ceiling of the railway vehicle 1. Prepare.

As shown in FIGS. 3 and 4, the exhaust blower 29a discharges the exhaust air taken into the air conditioner from the air conditioning exhaust intake 30a to the outside of the vehicle from the air conditioning exhaust sweep outlet 31a. The same amount of fresh outside air as the amount of air discharged to the outside of the vehicle is introduced into the

air conditioners

2a and 2b from the air conditioning fresh air port 27a. The air-conditioning fresh air outlet 27a is provided with an outside temperature sensor 95a that detects the temperature outside the vehicle.

As shown in FIG. 4, fresh air taken into the air conditioner 2a from outside the vehicle as the exhaust blower 29a is operated is mixed with return air taken into the air conditioner from the air conditioning return port 26a. The mixed fresh air and return air are supplied to the vehicle by the indoor fan 24a after the temperature and humidity are adjusted by the indoor heat exchanger 22a and the electric heater 25a.

As shown in FIGS. 2 and 3, a duct return port 44 a for taking in the air conditioner 2 a in the ceiling portion of the railway vehicle 1, and conditioned air in which the temperature and humidity are harmonized by each air conditioner are supplied to a guest room or the like. A conditioned air duct 32 that blows air from the cab 70 to the entrance / exit 72b and an exhaust duct 36a that guides the air discharged from the inside of the vehicle to the outside of the vehicle to the air conditioner 2a are arranged.

Basically, air conditioners corresponding to the entrance / exit platform 72a and the entrance / exit platform 72b where passengers and crew are not resident are not provided. For this reason, as shown in FIG. 2, the temperature and humidity of the entrance /

exit bases

72a and 72b are conditioned air supplied from the conditioned air duct 32 connecting the entrance /

exit bases

72a and 72b and the

air conditioners

2a and 2b, and the exhaust duct. It is adjusted by exhausting or venting air out of the vehicle by means of 36a and 36b.

The air conditioner 2a supplies conditioned air from the conditioned air supply port 28a to the conditioned air supply port 42a provided in the conditioned air duct 32. The conditioned air duct 32 has a plurality of openings (not shown) provided along the X direction at both ends in its Y direction. The conditioned air supplied to the conditioned air duct 32 is supplied to each part of the railway vehicle 1 through the opening described above in the process of flowing along the conditioned air duct 32.

As shown in FIG. 2, the exhaust air from the cab 70 and the entrance / exit 72a and the exhaust air from the catering preparation chamber 74 reach the catering preparation chamber 74 through the entrance / exit 72a as shown in FIG. In addition, after passing through an exhaust duct 36a having a duct exhaust port 37a provided above a cooking device (equipment) 50 (for example, a stove) provided in the catering preparation chamber 44, the air conditioner 2a has an air conditioning exhaust port 31a. It is taken in and discharged out of the vehicle by the exhaust blower 29a.

Also, the catering preparation room 74 has cooking equipment (facility) 50 such as a stove that causes exhaust heat and causes a large equipment load. For this reason, when the air conditioner 2a takes in return air including large exhaust heat generated from these cooking appliances (equipment) 50 from the air conditioning return port 26a (FIG. 4) via the duct return port 44a (FIG. 2), air conditioning. The operating rate of the compressor 20a constituting the refrigeration cycle included in the device 2a is increased, and the air conditioner 2a may consume a large amount of power.

In order to prevent the air conditioner 2a from taking in return air having a large amount of exhaust heat, air including a large amount of exhaust heat is supplied to the air conditioning exhaust intake from a duct exhaust port 37a provided above a cooking appliance (equipment) 50 such as a stove. The air is taken into the air conditioner 2a through 30a (FIG. 4) and discharged outside the vehicle by the exhaust blower 29a. With this configuration, the air conditioner 2a does not take in air containing a large amount of exhaust heat from the air conditioning return port 26a. Therefore, the operating rate of the compressor 20a and the outdoor fan 23a of the air conditioner 2a does not increase, and the power consumption of the air conditioner 2a is reduced. The increase can be suppressed.

FIG. 5 is a system diagram illustrating a relationship between input information to the air conditioning control device and target devices controlled by the air conditioning control device.
As shown in FIG. 2, the railway vehicle 1 includes in-

vehicle temperature sensors

92a and 92b for detecting the in-vehicle temperature on the walls of the

partition walls

16c and 16d, and a passenger number counting device 90a for counting the number of passengers getting on and off. It is provided on the ceiling in the vicinity of the side doorway 12b of 72a. Similarly, the passenger number counting device 90b is provided on the side entrance 12b of the entrance / exit 72b and the ceiling near the through passage.

Furthermore, the railway vehicle 1 includes a cooking appliance operation monitoring sensor 200 (not shown) that monitors the operating status of a cooking appliance (equipment) 50 such as a stove, microwave oven, and refrigerator provided in the catering preparation room 74.

The air-conditioning control device 60 that controls the air-

conditioning devices

2a and 2b detects variations in the vehicle interior temperature from the outputs of the vehicle

interior temperature sensors

91a, 91b, 92a, and 92b, so that the difference between the vehicle interior temperature and the vehicle interior temperature is reduced. The operating rate of the compressor 20a and the like is adjusted.

In the case where the outside air temperature is relatively high (such as in summer), the air-conditioning control device 60 detects the operation of a cooking device (facility) 50 (for example, a stove) that generates a large amount of heat from the output of the cooking device operation monitoring sensor 200. In this case, the air-conditioning control device 60 increases the rotational speed of the exhaust blower 29a built in the air-conditioning device 2a, and attracts the air whose temperature has been increased by the exhaust heat of the stove from the duct exhaust port 37a (FIG. 2). To discharge.

In addition to the configuration in which the duct exhaust port 37a is provided above the cooking appliance (equipment) 50 (for example, a stove), the air conditioning control device 60 detects the operation of the cooking appliance (equipment) 50 (for example, a stove). Thus, the rotation of the exhaust blower 29a is increased. As a result, the air conditioner 2a does not attract high-temperature return air from the air conditioning return port 26a (FIG. 4) via the duct return port 44a (FIG. 2), and therefore air containing large exhaust heat from the air conditioning return port 26a. As a result, the operating rates of the compressor 20a and the outdoor blower 23a are not increased, and an increase in power consumption of the air conditioner 2a can be suppressed.

In the case where the outside air temperature is relatively low (such as in winter), the air conditioning control device 60 detects the operation of a cooking device (facility) 50 (for example, a stove) with large heat generation from the output of the cooking device operation monitoring sensor 200. In this case, since the air conditioning control device 60 maintains the rotational speed of the exhaust blower 29a and lowers the operating rate of the electric heater 25a, it can reduce the amount of power consumed by the electric heater 25a and increase the power consumption of the air conditioning device 2a. Can be suppressed.

FIG. 6 is a system diagram of an air conditioning duct according to the second embodiment of the present invention. The air conditioning duct according to the second embodiment is provided on the ceiling of a railway vehicle having a first class cabin and a second class cabin. In the following, description of matters common to those described in the first embodiment will be omitted, and only matters necessary for the description of the second embodiment will be described.

The railway vehicle 1 including the air-conditioning duct according to the second embodiment has two air-conditioning apparatuses arranged on the roof along the X direction. One air conditioner (not shown) mainly air-conditions the entrance / exit stand 72a and the first class guest room 77a, and the other air conditioner (not shown) mainly air-conditions the second class guest room 77b and the entrance / exit stand 72b.

Passenger

number counting devices

90a and 90b for counting the number of passengers getting on and off the railway vehicle 1 are provided on the ceilings of the

entrances

72a and 72b, respectively.

Ventilation blowers

29a and 29b (FIGS. 3 and 4) built in the air conditioner allow air inside and outside the railway vehicle 1 so that the concentration of carbon dioxide in the vehicle that rises as passengers discharge does not exceed a predetermined value. Replace (ventilation). However, when only a small number of passengers are in the first class cabin 77a with a small capacity, the power consumption of the air conditioner 2a increases if the ventilation fan ventilates despite the fact that the concentration of carbon dioxide gas has not increased. There is a fear.

For example, excessive ventilation in summer increases the ratio of the ventilation load to the air conditioning load, so the operating rate of the compressor and the outdoor blower constituting the refrigeration cycle increases, and the power consumption of the air conditioner increases. In addition, the excess ventilation in winter also increases the ratio of the ventilation load to the air conditioning load, which increases the operating rate of the electric heater and increases the power consumption of the air conditioner.

Therefore, the number of passengers obtained from the passenger count device calculated by the passenger count device 90a provided in the entrance / exit 72a and the passenger count device 90b provided in the entrance / exit 72b is input to the air conditioning controller 60. The air conditioning control device 60 adds the number of passengers obtained from the

passenger count devices

90a and 90b to the carbon dioxide emission per unit time of one passenger, and calculates the estimated value of the carbon dioxide concentration in the vehicle. The air conditioning control device 60 controls the rotational speeds of the

exhaust blowers

29a and 29b based on the calculated estimated value.

As another control method, the air conditioning control device 60 calculates an estimated value of the human load by adding the number of passengers obtained from the

passenger count devices

90a and 90b to the calorific value per passenger, Based on the estimated value of the dynamic load, the rotational speeds of the

exhaust fans

29a and 29b are controlled.

Further, the above control method for calculating the estimated value of the human load by integrating the number of passengers and controlling the rotational speed of the exhaust fan based on the estimated value of the human load is the configuration of the air conditioning duct according to the first embodiment. It can also be applied to the case. That is, a pattern for calculating an estimated value of the human load by the number of passengers obtained from the passenger count device 90a and controlling the rotational speed of the exhaust blower 29a based on the estimated value of the human load, similarly, counting the number of passengers The estimated value of the human load based on the number of passengers obtained from the device 90b is calculated, and the rotational speed of the exhaust blower 29b is controlled based on the estimated value of the human load, and the

passenger count devices

90a and 90b are used. An estimated value of the human load is calculated by integrating the number of passengers to be used, and a pattern for controlling the rotational speed of the

exhaust blowers

29a and 29b based on the estimated value of the human load can be appropriately adopted. In that case, it respond | corresponds to the operation state of the cooking appliance (equipment) detected from the control corresponding to the fluctuation | variation of the vehicle interior temperature detected from the output of the vehicle interior temperature sensor shown in Example 1, or the output of the cooking appliance operation monitoring sensor. It is applied separately from control.

Thereby, since excessive electric energy consumed by the

compressors

20a and 20b, the

outdoor fans

23a and 23b, and the electric heaters 25a and 25b can be reduced, an increase in power consumption of the

air conditioners

2a and 2b can be suppressed.

In addition, a carbon dioxide concentration sensor is provided in addition to the in-vehicle temperature sensors (91a, 91b, 92a, and 92b) provided in the wall surface of the partition wall in the vehicle or the air conditioning return port of the air conditioner shown in FIGS. The above-described effects can also be obtained by inputting the output of the carbon dioxide concentration sensor to the air conditioning control device 60 (see the broken line portion in FIG. 5).

When two air conditioners are mounted on one railway vehicle and the operation (number of rotations) of the exhaust blowers contained in each air conditioner is controlled independently, the difference between the operation frequencies of both exhaust blowers or both exhaust blowers Based on the difference in the flow path length of the exhaust duct connected to, a phase difference occurs in the noise from both exhaust blowers. Due to this phase difference, a beat that pulsates the noise level in the vehicle may occur, which may impair passenger comfort.

Therefore, a condition for generating this beat is input to the air conditioning control device 60 in advance. Thereby, when the air-conditioning control device 60 determines the operating frequency of each exhaust blower based on each output of the cooking appliance operation monitoring sensor and the passenger number counting device or the carbon dioxide concentration sensor, avoid the condition that this beat occurs. Each exhaust blower can be operated.

Therefore, even when a plurality of exhaust blowers that are independently controlled are provided on one of the rail vehicles, no whistling due to noise generated from the exhaust blower occurs, and passenger comfort is hindered. A railway vehicle having no in-vehicle environment can be provided.

In the first embodiment, an example of the railcar 1 having a catering preparation room (section) 74 and a guest room 76 that may cause a large heat load will be described. In the second embodiment, the first class guest room 77a and the fixed capacity with a small capacity will be described. The example of the railway vehicle 1 having the second class guest room 77b having a large number has been described. In addition to the combinations described above, a railway vehicle having a compartment with a bicycle storage area or a luggage storage area and a guest room is assumed.

Designing the arrangement of conditioned air ducts and exhaust air ducts on the ceiling and the air conditioner with built-in exhaust blower according to the compartments and guest rooms provided on the railway vehicle increases the number of design steps and the number of types, which increases the number of manufacturing steps. Become. For this reason, it may be difficult to provide a low-cost railway vehicle.

On the other hand, even in the case of a railway vehicle that combines any of the above-described compartments and a guest room, the air-conditioning control device according to the present invention provides the heat load or carbonic acid of the compartment or guest room to be adjusted for temperature and humidity by the air-conditioner. It detects (estimates) the amount of gas discharged and controls the exhaust blower, compressor, outdoor blower, electric heater, and the like built in the air conditioner. Thereby, it is not necessary to redesign the arrangement of conditioned air ducts and exhaust air ducts corresponding to the combination of compartments and guest rooms, and the air conditioner incorporating the exhaust blower, and it is possible to provide a railway vehicle with low design cost. .
