Who is the Fridge: A Mystery Behind Your Food Storage!

The fridge is an essential appliance found in almost every household that helps us store our favorite food and drinks. It keeps our perishables fresh and ensures that we don’t waste money by throwing away food. However, have you ever thought about who the fridge really is? Who is the mystery behind your food storage? Let’s explore the history, mechanics, and tips for maintaining your fridge.

The History of the Fridge

Refrigeration technology has come a long way since the discovery of the icebox in the 1800s, which helped keep food cool while preventing it from spoiling. In the early 1900s, mechanical refrigeration was introduced, which allowed households to keep food fresh for a longer period of time. It wasn’t until the 1920s that refrigerators became mainstream and began to resemble the ones we are familiar with today.

Early refrigeration units were bulky and consumed large amounts of energy. The 1927 invention of Freon, a non-toxic refrigerant, was a game-changer that led to the development of more efficient and affordable refrigeration units.

The Mechanics of the Fridge

Before we dive into the mechanics, let’s understand the purpose of a fridge. A fridge is designed to maintain an optimal temperature range of 37°F to 40°F (3°C to 5°C) to preserve food and drinks for as long as possible. The basic components of a refrigerator include:

  • Compressor: This is the heart of the refrigerator and is responsible for pumping refrigerant fluid through the coils.
  • Evaporator: This removes heat from the inside of the fridge and transfers it outside.
  • Condenser: This releases the heat that was absorbed by the refrigerant fluid.
  • Expansion valve: This controls the flow of the refrigerant fluid, which helps regulate the temperature inside the fridge.

When you adjust the temperature on your fridge, you are essentially controlling the amount of cold air that is circulated throughout the unit. This is done by adjusting the settings on the thermostat, which is connected to sensors that detect the temperature inside the fridge.

Sizing and Placement of your Fridge

When choosing a refrigerator size, you should consider the size of your household, your eating habits, and the space available in your kitchen. Refrigerators come in various sizes, with the most common options being top-mount freezer, bottom-mount freezer, side-by-side, and French door.

When it comes to placement, it is essential to keep your fridge in a cool and well-ventilated area away from heat sources such as direct sunlight or the oven. Proper airflow is necessary, and therefore, keep a gap of at least 2 inches between the fridge and the wall to prevent overheating. Additionally, ensure that the doors can be opened fully without any obstruction.

Maintaining Your Fridge

Cleaning and Organization

Keeping your fridge clean and organized can improve its efficiency and extend its lifespan. Regularly removing expired items and wiping down the shelves, walls, and drawers can prevent the growth of bacteria and mold, resulting in a healthier environment for your food. Organizing your fridge by food type can also make it easier to find what you’re looking for and help prevent food waste.

Temperature Settings

It is crucial to maintain the proper temperature range in your fridge. Set your thermostat to the recommended range of 37°F to 40°F (3°C to 5°C). If you’re unsure, purchase an appliance thermometer and place it in the fridge to measure the temperature.

Seals and Gaskets

Keep an eye on your fridge’s door seals and gaskets, which are responsible for keeping the cold air inside. Over time, these seals can become cracked, damaged, or dirty, leading to air leaks and an increase in energy usage. Clean them regularly and replace them when necessary.


The coils in your fridge are responsible for transferring heat away from the unit. If they become clogged with dust and debris, they can become less effective, reducing the efficiency of the fridge. Dust off the coils at least once a year using a coil brush or vacuum attachment to ensure proper airflow.


Your fridge is a vital appliance in your home, and understanding its history, mechanics, and proper maintenance can help prolong its lifespan and keep your food fresh. Remember to keep your fridge clean and organized, maintain the proper temperature, and check the seals, gaskets, and coils regularly.


Here are some common questions about fridges:

  • Q: How long do fridges last?

    A: With proper maintenance, a fridge can last anywhere from 10 to 20 years.
  • Q: Can I place hot food directly in my fridge?

    A: No, it is not recommended to put hot food directly in your fridge as it can increase the internal temperature, potentially spoiling other food.
  • Q: Is it necessary to clean the coils?

    A: Yes, cleaning the coils can improve the efficiency of the fridge and reduce energy consumption.
  • Q: Can a fridge be repaired?

    A: Yes, most fridge issues can be repaired, and it is usually more cost-effective than purchasing a new one.
