![]() Hence this process is repeated every 5-6 hours. And the temperature sensor senses the temperature and when it goes above zero degrees then it turns off the heater. ![]() Every 5 to 6 hours the timer activates the heater and raises the temperature to zero degrees or 32 degrees Fahrenheit and maintains this temperature until the frozen ice melts. The timer is used to turn on the heater at the right time to prevent the formation of frost around the refrigerator. For frost-free technology to work properly, it is very important to have three components. So let’s understand how frost-free technology solves this problem. How does a frost-free refrigerator work? Working principle of a frost-free refrigerator?įrost basically forms when the water vapor strick with the coil. It not only saves your extra effort but also helps in retaining the original aroma and taste of the foods. So that the food items do not come in direct contact with the evaporating coils (or cooling coils) and prevent frost formation inside the freezer compartment. Frost-free refrigerators have hidden evaporator coils (also called cooling coils) and a blower inside the refrigerator is used to draw cold air into each compartment to maintain the required temperature. What is frost-free technology and how it workĪ frost-free refrigerator is a type of refrigerator that comes with frost-free technology which means you do not need to spend extra time cleaning the frost that forms in the freezer section.įrost-free refrigerators primarily use the convection or indirect cooling method. Without any further delay let’s get straight into the article. So stay tuned with us to know in detail about frost-free technology in refrigerators. So in this article, we will know what is a frost-free refrigerator and its working principle, advantages, and disadvantages. When we press this button, the evaporator coil around the freezer gets heated for some time so that all the frozen ice melts and the freezer becomes clean as before.īut nowadays refrigerators are getting advanced and they have come with auto defrost technology which is also known as frost-free technology. To avoid this phenomenon, the defrost button was present in older refrigerators. ![]() And if the ice in the freezer is allowed to freeze like this, a pearly layer of ice will freeze and eventually cover the entire freezer section with ice. If you have an older refrigerator or a single-door refrigerator, you would be aware of frost forming around the freezer section. And generally, nowadays we all have a refrigerator whether it is small or big in size, whether it is expensive or cheap. ![]() A refrigerator is an essential appliance that is definitely a must-have in your kitchen. ![]()
