BY evaporation of volatile liquid
No. Evaporation and condensation is enough.
low rates of evaporation.
The cooling element in a refrigerator is the refrigerant, which circulates through a series of coils and compressor to absorb heat from the interior of the fridge and release it outside. This process helps to maintain a low temperature inside the refrigerator to keep food fresh.
Evaporation is used for cooling in refrigerators. In refrigerator's freezing compartment, a gas, lets say freon is evaporated. Evaporation needs energy, therefore when freon evaporates it takes this energy from the surrounding, thus evaporation decrease the temperature of surrounding.
Refrigerators use evaporation to produce cooling because of the thermodynamic principle that when a liquid evaporates, it absorbs heat from the surroundings. In a refrigerator, a refrigerant liquid evaporates inside the coils, absorbing heat from the interior of the fridge and causing it to cool down. This process helps maintain a low temperature inside the refrigerator to keep food and drinks fresh.
Evaporation is improved at high temperature, low pressure, low humidity, etc.
Evaporation increase with the increase of temperature.

The FDA says on their website to keep the refrigerator set below forty degrees Fahrenheit. "Keeping the refrigerator at 40°F or below is important because - unlike most foodborne bacteria - Listeria will grow in the refrigerator, and it will grow faster at refrigerator temperatures above 40°F. And, the longer ready-to-eat, refrigerated foods are stored in the refrigerator, the more time Listeria has to grow. Finally, Listeria can spread from one food to another through spills in the refrigerator. That's why keeping the refrigerator clean is also important!"
High temperature, low pressure, low humidity, strong winds favors evaporation.
Absorption of the heat from the air due to evaporation of the liquid refrigerant.
