AIR-WATER COMBINED COOLING PASSIVE FEEDWATER DEVICE AND SYSTEM

摘要

The present invention relates to an air-water combined cooling passive feedwater device and to a system thereof. The air-water combined cooling passive feedwater device includes: a water cooling exchanger which cools the heat of a steam generator to be connected to the inside of a containing building by using a water cooling method; a cooling water tank for storing cooling water by condensing main steam generated in a steam generator; an evaporation steam pipe which is connected to the cooling water tank and in which a cooling water steam generated by the water cooling exchanger inside the cooling water tank is inserted; an air cooling exchanger which is connected to the evaporation steam pipe, cools, and liquefies the steam inserted into the evaporation steam pipe; and a condensate collection pipe which refills steam liquefied from the air cooling exchanger to the cooling water tank.
