WHAT IS CLAIMED IS:

1. A refrigerated vending machine, comprising:

a main cabinet;

a sensor circuit configured to detect a refrigerant leaked in the ma cabinet: and

a control equipment configured to operate a component of the refrigerated vending machine based on the detected refrigerant.

2. A refrigerated vending machine, comprising:

a main cabinet;

a refrigerated compartment located in the ma cabinet and configured to store chilled goods; a first sensor circuit configured to detect a refrigerant leaked in the refrigerated compartment; a second sensor circuit configured to detect a refrigerant leaked in the mam cabinet o utside of the refrigerated compartment; and

a control equipment configured to disable power to the refrigerated vending machine based on the detected refrigerant

3. A refrigerated vending machine, comprising:

a main cabinet;

a refrigerated compartment located in the main cabinet and configured to store chilled goods; a first sensor circuit configured to detect a refrigerant leaked in the refrigerated compartment; a second sen sor circuit configured to detect a refrigerant leaked in the main cabinet outside of the refrigerated compartment;

a battery configured to provide power to one or more of the first sensor circuit, the second sensor circuit and a control equipment; and

the control equipment configured to disable external power to the refrigerated vending machine based on the detected refrigerant during startup of the refrigerated vending machine.

4. The refrigerated vending machine of any of Claims 1-3, wherein the component includes a vending machine controller (VMC) configured to disable power to electrical components of the refrigerated vending machine based on a detected refrigerant leak.

5. The refrigerated vending machine of any of Claims 1-3, wherein:

the component is a smart GFCI device with an embedded gas sensor, and

the smart GFCI device is configured to disable power to the refrigerated vending machine based on the embedded gas sensor detecting the refrigerant

6. The refrigerated vending machine of Claim 5, wherein the smart GFCI device includes an indicator light to display a visual alert and an audible indicator to produce an audible alert in response to the embedded gas sensor detecting the refrigerant.

7. The refrigerated vending machine of any of Claims 1-3, wherein the component includes evaporator and condenser fans configured to dissipate the refrigerant from an inside of the mam cabinet and the refrigerated compartment.

The refrigerated vending machine of Claim 7, wherein:

the sensor circuit is further configured to detect a concentration level of the refrigerant in the main cabinet, and

the control equipment is further configured to variably control a speed of the evaporator and condenser fans based on the detected concentration level.

9. The refrigerated vending machine of claim 8, further comprising:

a feedback mechanism configured to variably control the speed of the evaporator and condenser fans.

10. The refrigerated vending machine of any of Claims 1-3, wherein the component includes a visual indicator configured to display a visual alarm based on a detected refrigerant leak.

11. The refrigerated vending machine of any of Claims 1-3, wherein the component includes an audible indicator configured to generate an audible warning based on a detected refrigerant leak.

12. The refrigerated vending machine of any of Claims 1-3, wherein the component includes a communicative indicator to transmit an alarm message based on a detected refrigerant leak.

13. The refrigerated vending machine of any of Claims 1-3, further including a communications unit configured to communicatively connect to another refrigerated vending machine.

14. The refrigerated vending machine of Claim 13, wherein:

the control equipment is further configured to transmit a signal to the other refrigerated vending machine indicating a detected refrigerant, and

power is disabled to other refrigerated vending machine.

15. The refrigerated vending machine of Claim 13, wherein the control equipment is further configured to:

receive a signal from the other refrigerated vending machine indicating that the other refrigerated vending machine detected a leaked refrigerant; and

disable power to electrical components of the refrigerated vending machine.

16. The refrigerated vending machine of any of Claims 1-3, wherein:

the component includes an electronic door lock on a door of the mam cabinet, and

the electronic door lock is configured to lock the door upon detection of the refrigerant until an authorized personnel unlocks the electronic door lock.

17. The refrigerated vending machine of any of Claims 1-3, wherein:

the component includes an exhaust fan separate from an evaporator fan and a condenser fan, and the exhaust fan is configured to variably adjust dispersion of the refrigerant.

18. The refrigerated vending machine of Claim 17, wherein:

the sensor circuit is further configured to detect a concentration level of the refrigerant in the main cabinet, and

the control equipment is further configured to variably control the speed of the exhaust fan based on the detected concentration level.

19. The refrigerated vending machine of any of Claims 1-3, wfierein:

the component includes a condenser fan configured to circulate air within the main cabinet, and the control equipment is configured to reverse a direction of the circulated air to reduce a concentration of the refrigerant.

20. The refrigerated vending machine of any of Claims 1-3, further comprising:

a battery' configured to power the sensor circuit when input power is not supplied by an external power source,

wherein the battery' is connected to the sensor circuit.
