Most, if not all, of the Fridges and Freezers in Australia will have a classification rating, based on the ambient temperature that they are designed to operate in.
Each Unit should have a visible rating plate, showing the Temperature Class, normally with 1 or 2 letters, but maybe using the class rating name.
- SN = 10°C to 32°C (Extended Temperature)
- N = 16°C to 32°C (Temperate)
- ST = 18°C to 38°C (Subtropical)
- T = 18°C to 43°C (Tropical)
On checking my two fridge/freezers, I found that I have one that is “T” and one that is “N”. My reason for looking into this today, is that my “N” rated unit has just died, and I am looking into replacing it. As it is kept in the garage, the temperature often exceeds the ambient maximum of 32°C, so the next one must be a “T” rating, to keep energy use down (electricity cost) and maybe a longer life.
