18-compartment Room Temperature Refrigerator

If there are not many items stored, you can place a larger bottle filled with saltwater inside the vending machine. This will help to balance the internal temperature difference of the cabinet, thereby reducing the number of start-stop cycles for the compressor and extending its lifespan.

2. The condenser of an automatic vending machine is typically located beneath the steel panel of the cabinet. Therefore, the refrigerator should be placed in a well-ventilated area, and dust on the cabinet exterior should be regularly wiped away to enhance the condenser's efficiency and improve cooling performance, thereby saving energy. Over time, as refrigerators and fresh-keeping cabinets are used, the interior of the vending machine may frost over easily. It is necessary to defrost the refrigerator every few days (about every seven days) to maintain optimal cooling efficiency.

3. If the condenser of the unattended vending machine is finned, it should be cleaned with a brush about once a month to enhance its heat dissipation efficiency.
