Title:
CONDENSER, COOLING SYSTEM, AND OPERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/018082
Kind Code:
A1
Abstract:
The purpose of the present invention is to achieve a cooling system that adjusts the amount of heat removed by a condenser, and maintains, at or below a specified temperature, the temperature of a refrigerant flowing into a heat exchanger, the cooling system thereby being capable of suppressing an increase in cost. If the nitrogen concentration inside a containment vessel (50) decreases and the amount of heat removed by the condenser (1) increases, the amount of cooling water to the condenser (1) is adjusted by a flow rate adjustment valve (5) and the amount of heat removed by the condenser (1) is controlled. Further, low-temperature cooling water is supplied from a bypass pipe (12) to a mixer (4) and is mixed, in the mixer (4), with high-temperature cooling water which has flowed from the condenser (1), and the temperature of cooling water caused to flow into an external heat exchanger (8) is lowered to the specified temperature of the external heat exchanger (8) or lower.
