Title:
COOLING UNIT
Document Type and Number:
Japanese Patent JP2020085399
Kind Code:
A
Abstract:
To provide a cooling technique capable of exhibiting sufficient cooling capacity by air-water cooling combination, and capable of saving water and energy.SOLUTION: An integrated type cooling unit 10 includes a refrigerant circuit 38 in which a compressor 40, an air-cooling condenser 42, a water-cooling condenser 44 and the like are connected by a refrigerant pipe 56, and is arranged in a ceiling 14 of a prefabricated type refrigerator 12. In a water supply pipe 30 connected to the water-cooling condenser 44, a water-cooling solenoid valve 58 is interposed. A plurality of sensors are provided in the refrigerant circuit 38, and measurement data is outputted to a control part 85. The control part 85 compares each of the measurement data with an opening condition 56 of the solenoid valve 58, and when the condition is satisfied, it opens the solenoid valve 58 and shifts from an air-cooling operation to an air-water-cooling operation. At the same time, after the shift to the air-water-cooling operation, the control part compares each of the measurement data with a closing condition 87 of the solenoid valve 58, and when the condition is satisfied, it closes the solenoid valve 58 and returns to the air-cooling operation from the air-water-cooling operation.SELECTED DRAWING: Figure 3
