Description

[0001]
[Technology to which the invention belongs]
The present invention relates to a carrier using a sealed passenger car of cableway equipment, and relates to a carrier with an air conditioner provided with an air conditioner in the passenger car.
[0002]
[Prior art]
There are two types of passenger cableway facilities: a chair using a chair and a carrier using a passenger car. The cableway facilities are suitable for rough terrain due to their characteristics, and many are constructed mainly in mountainous areas. However, recently, the construction cost is low compared with other transportation systems, and attempts have been made to adopt it as an urban lightweight transportation system with a transportation distance of several kilometers within the suburbs of the city. In such a case, that is, when a cableway facility is installed near the city, it is necessary to provide passengers with the same level of convenience and comfort as other urban transport systems.
[0003]
Among these, as one of the devices for comfort, the invention of mounting an air conditioner on a passenger car of a transporter has been proposed. Japanese Patent Application No. 6-74168 “Ropeway system with air conditioning equipment” is an invention filed by the applicant of the present application on March 17, 1994. The present invention relates to a cableway system in which a plurality of transporters are grouped, and power supply equipment is mounted on one of the transporters, and power is supplied to the air conditioning equipment provided for each of the other transporters. However, the number of cableway facilities that operate by grouping a plurality of carriers is small, and it is not applicable to the automatic circulation type cableway that operates by accelerating and decelerating each of the currently mainstream carriers. Further, Japanese Patent Application No. 7-200393 “Carrier with air conditioner for rope pulling type transportation equipment” is an invention filed by the present applicant on July 13, 1995. In the present invention, a power supply device for an air conditioner is mounted on each carrier, and a gas turbine engine is used as a drive device for a generator. However, even in the case of a gas turbine engine, since a liquid fuel is mounted on the transporter, a safety measure including a fire extinguishing device is also required. In addition, the gas turbine engine is expensive, and a corresponding technique is required for maintenance and inspection, and there is a difficulty in handling.
[0004]
[Problems to be solved by the invention]
An object of the present invention is to provide a lightweight, quiet, safe and maintenance-free air conditioner that does not use a flammable liquid fuel in a passenger car of a carriage of a cableway facility, and that does not have a compressor in an air conditioner. It is in providing a carrier with an air conditioner.
[0005]

A temperature sensor is provided. A battery for power is installed under the seat.
[0008]
A DC power source supplied from the battery and a signal obtained by measuring the temperature in the cabin with a temperature sensor are input to the control unit. In such a control unit, the temperature signal from the temperature sensor is compared with the temperature preset in the control unit, and the power supply of the cooling unit, the blower fan, the intake fan, and the exhaust fan is changed depending on the magnitude of the difference, That is, the cooling capacity is changed.
[0009]
In the exhaust heat chamber, outside air is taken in by three intake fans, and if it flows between six heat sinks, the heat from the heat sink is taken away by the air, and further, the air whose temperature has increased by the three exhaust fans is moved outside the passenger car. Discharge. On the other hand, between the passenger car and the cooling room, the air blown by the passenger is sent to the cooling room by two air blowing fans, is cooled in contact with the heat absorption plate of the cooling unit, and is again sent to the guest room by the two air blowing fans. Discharge towards. In other words, air is circulated between the cabin and the cooling chamber for cooling.

【The invention's effect】
Cableway facilities are not limited to mountainous transportation, but recently the cost of construction has been reviewed, and the introduction and examination of short- and medium-sized transportation systems in the suburbs of cities are being studied and planned. In that case, it is necessary to ensure the same level of comfort and safety as other transports.
[0020]
In particular, the present invention relates to a portable device having an air conditioner in a passenger cabin in order to maintain passenger comfort. A space for installing an air conditioner is formed in the upper part of the passenger car. Further, the space is divided into a heat exhaust chamber and a cooling chamber. The cooling unit of the air conditioner is configured by arranging a plurality of thermoelectric elements in a lattice shape, and utilizes the fact that heat is exchanged by the Peltier effect when a voltage is applied to both ends of the thermoelectric elements. The cooling unit absorbs the heat in the passenger car and transfers it to the heat radiating plate on the exhaust heat chamber side, and the warm air is discharged out of the passenger car by a plurality of intake fans and exhaust fans provided on the side surfaces of the exhaust heat chamber. Separately from this, the cool air that has been deprived of heat in contact with the heat absorption part of the cooling unit in the cooling chamber is circulated in the cabin by a plurality of blower fans incorporated between the top plate and the partition plate. As for the power supply, multiple batteries are installed under the seat. In addition, a control unit for setting the temperature of the air conditioner, starting and stopping the operation, and a temperature sensor for setting the temperature in the cabin are also installed.
Thus, the conventional compressor is not used for the air conditioner of this invention. Therefore, since there are few mechanical components and there are few rotation parts, it is excellent in maintainability and quietness. Further, since no fuel or the like is mounted, the effect of the present invention is great in terms of safety against fire.
