In a railway-car total heat exchange ventilation system for railway-car air-conditioning ventilation equipment, a value of heat load outside the car, 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, calculated by multiplying the amount of average heat generation per passenger by the current number of people on board inside the car calculated from the passenger weight detected by the passenger weight detection device. 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.
