15 Interesting Facts About Refridgerator That You Never Knew
How to Choose a Refrigerator

Refrigerators (sometimes called fridges) are kitchen appliances that keep food and beverages cold. They're used at home and in hotels, offices, and college dorm rooms.

Certain refrigerators come with smart features like cameras and sensors. Some refrigerators have touchscreens that allow you to watch videos and search for recipes, look up family calendars, and shopping lists. You can also leave notes.

Control of Temperature

The correct refrigerator temperature ensures food is safe to store which slows down the degradation of many food items due to spoilage. This is particularly important for foods such as eggs and milk, which can quickly rot when exposed temperatures that are not ideal but stay stable in the refrigerator. Refrigerators can be used to store pharmaceuticals like drugs or vaccines that lose their efficacy with time. Refrigerator monitoring systems are in place to ensure that a medical facility or laboratory keeps an appropriate cold chain.

The internal thermal insulator of a refrigerator keeps its contents cooler than surrounding air. The heat pump is used to move warm air from the outside of the refrigerator into an insulated compartment, from which it becomes very cool. The refrigerator also has a controlled system that activates the cooling system when the internal temperature exceeds the threshold set by the manufacturer. This prevents the growth of bacteria within the refrigerator.

Each refrigerator zone is designed to serve a specific function. The lower shelves are ideal for storing perishable items such as fresh meats and vegetables, which require the minimum temperatures to preserve their taste and texture. Clear shelves allow cool air to circulate around the refrigerator. A separate drawer for deli can be used to store soft cheeses and cured meats for the perfect charcuterie board.

Refrigerators also come with glass or stainless steel doors to protect the interior and facilitate cleaning. Certain refrigerators have a door alarm that can be programmed. It will notify you when the fridge or freezer is not closed for too long. You can set them to alert multiple people, and in escalating levels depending on your requirements. You can set them up to send temperature graphs via text or email.

Many refrigerators come equipped with thermometers however for those that don't, an independent appliance thermometer is a cost-effective way to monitor the fridge and freezer temperature. It is important to check the temperature of the freezer and fridge often, especially when there is an outage in power or you manually altered the temperature setting. The ideal temperature for both the freezer and refrigerator is 40 degrees Fahrenheit.

Storage Capacity

The capacity of your refrigerator is a key factor when choosing the model that is most suitable for your requirements. There are numerous sizes to pick from, ranging from small refrigerators with a capacity of less than 15 cubic feet, to larger models that hold over 26 cubic feet. Take into consideration your family's cooking preferences and the amount of people living in your home to figure out which size is suitable for you. For two people the average of 11-13 cubic feet of refrigerator space is enough and 18 to 22 cubic feet is recommended.

Take a look at the depth of the fridge, in addition to the overall space. Some models are larger than others, allowing them to fit in small spaces and not take up too much space under your counters. Cabinet-depth refrigerators are another option, and have a depth that is roughly the similar to the standard front of a kitchen cabinet (though handles can protrude a little more). They can be a great option for homes where counter space is a problem and can look more sleek than traditional refrigerators.

Find out about the refrigerator's energy consumption and noise level when shopping. Many manufacturers offer quieter options for use in homes, and some offer refrigerators that consume less energy than comparable models. Look for the yellow Energy Guide label on appliances to learn about the typical energy consumption of the particular model. Also, test the model's operation by opening and closing the doors.

Most modern refrigerators include the pantry drawer. It is a full-width compartment with separate temperature controls that can be used to store many different items. These drawers are ideal for storing party trays as well as wine, as they permit you to store them at a specific temperature. These drawers can be programmed to store wines, deli foods, and soft drinks, based on the model.

Energy Efficiency

Refrigerators consume a lot energy. It is therefore important to choose a energy-efficient refrigerator. Over the years, refrigerators have become increasingly energy efficient. Motors, insulation, and magnetic door seals have all improved over time, which means that a newer fridge will use less power than a previous model of the same size. It is possible to reduce the energy consumption of your refrigerator further by purchasing a highly energy efficient model. A refrigerator with an Energy Star rating will use less energy than a model at least ten years old.

Energy efficiency is particularly important for consumers who have limited access to electricity grids. Refrigerators are often one of the most expensive appliances for off-grid households, and their large energy consumption means they require large solar home systems (SHS) that are unaffordable for many families making less than $2 a day. The annual energy consumption of a refrigerator is therefore a crucial factor in determining whether it is cost-effective for consumers to buy and run (PATH and WHO 2013; McCarney et al, 2012).

To understand how fridges work first, we must understand the basic refrigeration cycle. A refrigerator cools by pushing a liquid refrigerant through a sealed device that begins as a liquid, then is pushed through a compressor that compresses the liquid into a liquid. This vapor then flows into coils located on the exterior of the fridge where it draws heat from the fridge, then cooling down and turning back to liquid. This process is repeated over and over again and keeps food cold as the vapor flows through the coils.

Although refrigerators are among the most expensive appliances available to off-grid consumers, improving their energy efficiency makes them more affordable. By reducing the amount of energy they use, a refrigerator can be powered by less energy and lower the overall system cost for consumers. The savings in energy are contingent on the dimensions, design and other features of a refrigerator. For instance, ice-makers and through-the-door water dispensers can add cost, but they can also significantly increase the energy consumption and, in turn, increase the amount of SHS needed to power it.

Maintenance

Regular maintenance and inspections can significantly increase the lifespan of your refrigerator. Check the condenser, the ice maker, and the defrost drain. Also, check the seals on the door. Additionally, cleaning and replacing water filters are essential. These simple tasks can help you prolong the life of your refrigerator as well as save money on your energy costs.

Cleaning the interior of your fridge on a regular basis is the easiest and most efficient way to keep it in good condition. This includes throwing out old food items, cleaning shelves and crispers, walls and the inside of your refrigerator's doors. This will prevent unpleasant odors as well as reduce the risk of foodborne illnesses. fridge sale is also recommended to regularly check the temperature of your refrigerator with a fridge thermometer. A refrigerator that isn't properly maintained could experience temperature fluctuations, which can lead to food spoilage and a higher electricity bill.


The condenser coils of your refrigerator should be cleaned at least at least twice a year. This will eliminate any dirt, grime, hair or other debris that may have accumulated. These coils, which are basically radiators that help remove heat from the refrigerator are located at the bottom or back of the appliance. These coils aren't able to release heat as efficiently when they're dirty. Your refrigerator will use more energy to run.

Another thing you should be checking regularly is your refrigerator's gasket that is designed to form an airtight seal between your fridge and your home's ductwork. This is vital to ensure that your fridge's contents stay cold But over time, the seal can become worn down from greased fingerprints, sticky syrups, and dripping beverages. Wipe your fridge's seal with the help of a damp towel to keep it in good condition.

In the end, it's recommended to regularly clean the drip pan, which is typically located beneath the compressor unit. The drip pan is responsible to collect the water that is drained from the defrost cycle of the refrigerator. It should be cleaned regularly to prevent the development of mold and unpleasant smells.
