3 terms and definitions

The terms and definitions defined in GB/T 28493 and the following apply to this document.

3.1

Refrigerated vending machines refrigeratedbeveragevendingmachines

Commercial refrigeration appliances for bottles, cans, and other packaged beverages with self-sale capabilities.

3.2

Availablerefrigeratedcapacity

It is used for pre-cooling, refrigerating, and selling after the space enclosed by the inner boundary of the refrigerated box is reduced, and the space occupied by the refrigeration system inside the refrigerated box of the vending machine is eliminated.

Space for bottles, cans and other packaged beverages.

Note. The non-isolated space inside the refrigerator for packaging beverage sales, or the space separated by detachable partitions and heat insulation materials is considered a cooling space

This part is used as a refrigerated space for selling ability and temperature tests.

3.3

Nonrefrigeration space

The space inside the vending machine for the sale of other non-refrigerated goods, which is separated from the refrigerated space by non-removable insulation materials.

Note. The non-refrigerated space with heating function is also part of the space.

3.4

Low power mode

In the inactive (sale) state, no user intervention is required, and the vending machine enables automatic adjustment of lighting, cooling, and/or other energy use systems.
