Title:
COLD/HOT WATER GENERATOR AND COOLING LINE STORAGE METHOD DURING HOT WATER SUPPLY OPERATION OF CLOD/HOT WATER GENERATOR
Document Type and Number:
Japanese Patent JP2020200508
Kind Code:
A
Abstract:
To provide a cold/hot water generator capable of reducing risk of occurrence of corrosion of a cooling water line during hot water supply operation of a cold/hot water generator, and a cooling water line storage method during hot water supply operation of the cold/hot water generator like this.SOLUTION: The present invention, in order to solve the above problem, constitutes a cold/hot water generator including: a cooling water line for circulating the cooling water to/from a cooling tower by connecting with an inlet side valve and an outlet side valve of the cooling water to a piping connected to the cooling tower; and a hermetically sealed tank that is connected to the cooling water line, reserves the cooling water as reserved water inside, holds a gas phase part above water surface of the reserved water, and allows inflow and outflow of the cooling water. Furthermore, a cooling water line storage method during hot water supply operation of the cold/hot water generator that stores the cooling water line at full by closing both of the inlet side valve and the outlet side valve and by water in which an antirust agent is introduced.SELECTED DRAWING: Figure 1
