How to Choose a Refrigerator

Refrigerators (sometimes called fridges) are kitchen appliances that keep food and drinks cold. They are used in offices, homes in hotels, restaurants and college dorms.

Some refrigerators have sophisticated features such as sensors and cameras. Certain refrigerators come with touchscreens that let you view videos or search for recipes, view family calendars and shopping lists, or even write notes.

Temperature Control

The proper temperature in the refrigerator ensures food is safe to store, slowing the deterioration of many foods due to spoilage. This is particularly important for foods such as eggs and milk, which could quickly turn rotten when exposed to ambient temperatures but remain stable in the refrigerator. Refrigerators can also be used to store pharmaceuticals, such as vaccines or drugs which lose their effectiveness over time. Refrigerator monitoring systems are in place to help ensure a medical facility or laboratory maintains the safety of its cold chain.

A refrigerator is equipped with an internal thermal insulation to keep its contents cooler than the surrounding environment. It utilizes an energy source to transport warm air outside the refrigerator into an insulated compartment where it is extremely cold. The refrigerator also has a controlled system that activates the cooling system when the internal temperature rises above a pre-set threshold. This stops the growth of bacteria inside the refrigerator.

Each refrigerator zone is designed to serve a specific function. The lower shelves are perfect for storing perishable items such as fresh meats and vegetables that require the lowest temperatures to preserve their flavor and texture. Clearing the shelves allows cool air to circulate throughout the refrigerator. A separate drawer for deli can be used to store soft cheeses and cured meats to create the perfect charcuterie board.

Certain refrigerators have glass or stainless steel door to safeguard the interior. They also make it easier to clean. Some refrigerators include a door-alarm that can be programmed. It will alert you if the fridge freezer is left open too long. They can be programmed to alert multiple individuals and in escalating levels based on your needs. They can also be programmed to record temperature and send graphs remotely via email or text.

Many refrigerators come equipped with thermometers however for those who don't, a stand-alone appliance thermometer is an inexpensive way to check the temperature of your freezer and fridge. It is important to monitor the refrigerator and freezer temperature frequently, particularly in the event of a power failure or when temperature settings are changed manually. Ideally, both the fridge and freezer should be set to 40 degrees Fahrenheit or less.

Capacity for Storage

The capacity of your refrigerator is an important factor in deciding on the model that best suits your needs. There are numerous sizes to choose from, ranging from tiny refrigerators that have a capacity of less than 15 cubic feet, to large models that can hold over 26 cubic feet. Take into consideration your family's cooking preferences and the number of people living in your house to determine the best size for you. For two people with a family of two, an average of 11 to 13 cubic foot of refrigerator space is adequate and 18 to 22 cubic feet is recommended.

In addition to assessing the total interior space, look at the depth of your fridge. Certain models are larger than others to allow them to fit into tight spaces and not take up too much space under your counters. Cabinet-depth refrigerators are another alternative. Their depth is comparable to that of a standard kitchen cabinet, but the handles may extend a little further. They are a great choice for areas where counter space is a problem and also look more sleek than traditional refrigerators.

Be sure to inquire about the energy consumption of the refrigerator and noise level when shopping. Many manufacturers offer quieter refrigerators suitable for homes. Some offer refrigerators with less energy consumption than comparable models. Look for the yellow Energy Guide label on appliances to find out the typical energy consumption of the specific model. Test the model by opening and shutting its doors.

The majority of modern refrigerators have the pantry drawer. It is a full-width area with separate temperature controls that can be used for storing many different things. These drawers are ideal to store party trays and wine, as they permit you to keep them at certain temperatures. Based on the model, these drawers could include pre-programmed settings to store wines, deli meats and soft drinks.

Energy Efficiency

Refrigerators consume a lot energy. Therefore, it is crucial to select a refrigerator that is energy efficient. As time has passed refrigerators have become more energy-efficient. Insulation, motors, as well as magnetic door seals have been improved over time, so the latest refrigerator will consume less energy than a model older in the same size. You can reduce the electricity consumption of your refrigerator even more by choosing one that is energy efficient. A refrigerator that is Energy Star rated will use a lot less energy than a comparable model that is ten years old or older.

It is crucial to think about the energy efficiency of consumers who have limited access to electricity grids. Refrigerators are often among the most costly appliances for off-grid households Their high energy consumption means that they require large solar home systems (SHS) that are unaffordable for many families making $2 per day or less. The annual energy consumption of a refrigerator is therefore an important factor in determining whether it is affordable for consumers to buy and run (PATH and WHO 2013; McCarney et al, 2012).

To understand how fridges function it is important to understand the basic refrigeration cycle. A refrigerator cools itself by pushing a refrigerant fluid through an enclosed system. It begins as a fluid, then goes through the compressor that compresses it to form an vapor. This vapor then flows into coils located on the exterior of the fridge, where it draws the heat from the fridge, settling down before turning back into a liquid. This process is repeated repeatedly and keeps food cold as the vapor moves through the coils.

Refrigerators remain among the most expensive appliances that consumers who are not connected to the grid can purchase however, improving their energy efficiency will make them more affordable. By decreasing the amount of energy they use the refrigerator can be powered by a smaller SHS and reduce the overall system cost for consumers. Based on the dimensions, style, and features of the refrigerator, the savings on energy will vary. For instance, ice-makers and through-the-door water dispensers increase cost, but can substantially increase the energy consumption, which in turn increases the SHS required to power it.

Maintenance

The life span of a refrigerator could be significantly improved by regular maintenance and inspection. This can be done by checking the condenser coils, the ice maker, defrost drain and the gasket seal on the door to make sure that it is in good working order. Cleaning and replacing the water filter is also important. These simple maintenance tasks will aid in prolonging the life of your refrigerator and also save money on your energy bills.

Cleaning the inside of your fridge on a regular basis is the most efficient and efficient way to keep it in good condition. This means throwing away old food items, wiping down shelves and crispers, walls, and the interior of your refrigerator's doors. This can reduce the risk of foodborne illnesses and unpleasant smells. It is recommended to check regularly the temperature of your refrigerator by using a fridge thermometer. Refrigerators that aren't maintained may experience temperature fluctuations that could cause food waste and higher electric costs.

It is also crucial to clean the condenser coils on your refrigerator at least twice per year to get rid of any dirt hair, dust, and other debris that could have been accumulating. The coils are situated on the bottom or rear of your appliance and are basically radiator-like components that assist in helping remove heat from your refrigerator. When these are dirty, they aren't able to release heat as effectively and your fridge will require more energy to run.

Check your refrigerator's seal that is designed to create an airtight seal between your refrigerator and the ductwork in your home. It is essential to ensure that your fridge's contents remain cool. However, over time, the seal could be worn down by greasy fingerprints and sticky syrups. To keep your fridge's gasket in good condition, regularly wipe it down with the help of a damp cloth.

It is also a good idea, to clean the drip tray, which is typically beneath the compressor unit of the refrigerator. This pan is used for collecting the water from the refrigerator's defrost cycle. It is recommended to clean it regularly to prevent the development of mold and unpleasant odors.
