A hot-or-cold chamber and a second hot-or-cold chamber containing a heater and an evaporator are defined in an independent chamber, and the two evaporators are connected to a condensing unit of a refrigerator through a capillary tube, respectively. In an internal cooling system for a vending machine that connects piping in parallel to keep products stored in each chamber cool, this device is used to switch between two types of capillary tubes with different resistances for the evaporator installed in the second hot-or-cold chamber. In the operation mode in which it is connected with a solenoid valve and both chambers are cold, the capillary tube with the larger resistance is selected from the two types of capillary tubes mentioned above, and the first and second hot or cold chambers are hot and cold, respectively. 1. An internal cooling device for a vending machine, characterized in that in an operating mode, a capillary tube with small resistance is selected by switching a solenoid valve. (2) Utility Model Registration Scope of Claims In the refrigerator compartment cooling system described in claim 1, the solenoid valves connected to two types of capillary tubes corresponding to the covaporators of the second hot-or-cold chamber switch the operation mode. An internal cooling system for a vending machine, characterized in that both solenoid valves are controlled to be closed in an operation mode in which the second hot-or-cold chamber is hot. .
