When you open the freezer and place items inside, you may notice steam or condensation coming out from the freezer. This phenomenon occurs due to the difference in temperature between the items you're placing inside and the cold air already present in the freezer.
Here's what happens:
Warm Air from Outside: When you open the freezer door, warmer air from the surrounding environment enters the freezer. This air contains moisture in the form of water vapor.
Warm Air Meets Cold Air: The warm air from outside comes into contact with the cold air inside the freezer. As warm air cools down rapidly, its ability to hold moisture decreases.
Condensation: The cooling process causes the water vapor in the warm air to condense into tiny water droplets. This is the steam you see coming out from the freezer. The process is similar to the formation of dew on a cold surface during the morning.
Steam Subsides: As the newly introduced warm air cools down, and its moisture condenses, the steam will gradually subside, and the freezer's internal temperature will stabilize again.
It's important to note that this process is entirely normal and does not indicate any issues with your freezer. In fact, modern freezers are designed to handle temperature changes efficiently. However, to maintain the best cooling performance and energy efficiency, it's a good practice to minimize the time the freezer door is kept open and avoid placing hot or warm items directly into the freezer. Allow hot food or beverages to cool to room temperature before placing them inside the freezer. This helps reduce the amount of warm air entering the freezer, minimizing the formation of steam and preserving the frozen items more effectively.
