Title:
LIQUID CONSTANT-TEMPERATURE APPARATUS
Document Type and Number:
Japanese Patent JP2002130847
Kind Code:
A
Abstract:
To provide a liquid constant-temperature device that can be prevented from becoming unusable.
A heat exchanger 16 is constituted to cool a liquid to be cooled by performing heat exchange between the liquid and a refrigerant. A temperature sensor 11b is constituted to detect the state of the refrigerant passed through the heat exchanger 16. A compressor 15 is constituted to compress the refrigerant. A fan motor 23 is constituted to cool the compressed refrigerant. A control computer 17 is constituted to control the number of revolutions of the fan motor 23 based on the detected value of the sensor 11b. Consequently, the refrigerant is maintained at a temperature higher than the freezing temperature T1 of the liquid to be cooled.
