The present invention is to realize a railway-car total heat exchange ventilation system for railway-car air-conditioning ventilation equipment, which is capable of maintaining comfort inside the car that would be impaired by rapid variations in the external air temperature and variations in the temperature inside the car, or the like, accompanied by the change in the number of people on board caused by passengers getting on/off at a station, or the like. In the total heat exchanger control unit of the control device that controls the total heat exchanger, a value of heat load outside the car, which is calculated on the basis of the difference between the external air temperature detected by the car-exterior temperature detection sensor and the temperature inside the car detected by the car-interior temperature detection sensor, is compared with a value of heat load inside the car, which is calculated by multiplying the amount of average heat generation per passenger (approximately 0.115 kW) by the current number of people on board inside the car calculated from the passenger weight detected by the passenger weight detection device, and then a variation in a future temperature inside the car is predicted and switching between a heat exchange operation of the heat exchanger and a normal operation is carried out on the basis of the predicted result, so that the comfort inside the car is maintained. |
