Title:
COOLING DEVICE FOR AUTOMATIC VENDING MACHINE
Document Type and Number:
Japanese Patent JP3190397
Kind Code:
B2
Abstract:
PURPOSE: To lower condensation capacity, to increase high pressure and to augment the quantity of a refrigerant circulated when high pressure reaches a fixed value or less by closing a solenoid valve when the detecting pressure of a pressure sensor reaches a specified value or less.
CONSTITUTION: A compressor 6, a first condenser 8A, a third solenoid valve 20, a second condenser 8B, and capillary tubes 10 and evaporators 4A, 4B mounted to each of a plurality of good housing chambers 2A, 2B are successively connected annularly. A pressure sensor 22 installed on the outlet side of the second condenser 8B and a bypass circuit 21 connecting a section between the first capacitor 8A and the third solenoid valve 20 and a section between the second condenser 8B and the pressure sensor 22 are provided, and the third solenoid valve 20 is closed when pressure detected by the pressure sensor 22 reaches a specified value or less.
