Title:
AUTOMATIC VENDING MACHINE
Document Type and Number:
Japanese Patent JP2017162318
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To further reduce power consumption of an automatic vending machine by enhancing a heat pump warming ability and using heat pump warming operation at a low outdoor temperature time in which a load in a cooling chamber is reduced.SOLUTION: The automatic vending machine comprises: a three-way valve 57 for flowing a coolant which is discharged from a compressor 5, into an outside-cabinet condenser 40 through an inside-cabinet condenser 46 when warming inside of a first cooling/warming chamber 2 by the inside-cabinet condenser 46, and flowing the coolant which is discharged from the compressor 5, into the outside-cabinet condenser 40 without through the inside-cabinet condenser 46 when the first cooling/warming chamber 2 is not warmed by the inside-cabinet condenser 46; an expansion mechanism 53 provided in a bypass flow channel between a solenoid valve 52 and an outside-cabinet evaporator 41; an inside-cabinet weak cooling evaporator 54 for cooling a commodity in a dedicated cooling chamber 4 at temperature higher than that of the internal evaporator 10; and a solenoid valve 56 for opening and closing a branch flow channel between a branch point for branching a coolant flow channel to the inside-cabinet weak cooling evaporator 54 and the inside-cabinet weak cooling evaporator 54.SELECTED DRAWING: Figure 1
