Document Type and Number:
Japanese Patent JP2003214682
Kind Code:
A
Abstract:
To provide a temperature control apparatus preventing a problem of a water hammer even in a large capacity refrigerating unit.
In the brine temperature control apparatus, a temperature of the brine in a tank 41 provided in a brine fluid circulating circuit 40 is controlled by using the three-way proportional control valve 46. In the three-way proportional control valve 46, clear changing of opening and closing as in an ON/OFF solenoid valve is not carried out, and opening of the valve supplying chilled brine to the tank 41 is continuously adjusted by a temperature controller 53 in proportion to a temperature detection signal of the brine in the tank 41 by a temperature sensor 52.
