How to Choose a Refrigerator

Refrigerators are kitchen appliances utilized to keep food and beverages cold. They are used at home as well as in hotels, offices and refridgerator (great post to read) college dorm rooms.

Certain refrigerators come with smart features like sensors and cameras. Some refrigerators have touchscreens that let you watch videos, search for recipes, view family calendars and shopping lists or even leave notes for family members.

Temperature Control

The correct refrigerator temperature ensures food is safe to store and slows the degradation of many foods due to spoilage. This is particularly important for foods such as eggs and milk, which could quickly rot when exposed ambient temperatures but remain stable in the refrigerator. Refrigerators are also used to store pharmaceutical products like drugs and vaccines which lose effectiveness as time passes. Refrigerator monitoring systems are available to help ensure a medical facility or laboratory has a safe cold chain.

A refrigerator is equipped with an internal thermal insulator that helps keep its contents colder than the surrounding air. It utilizes a heat pump to move warm air outside the refrigerator into an insulated compartment, where it is extremely cold. The refrigerator also has a temperature control system that switches on the cooling system when the internal temperature exceeds the threshold set by the manufacturer. This stops the growth of bacteria in the refrigerator.

Each zone of the fridge is designed to serve a particular function. The lower shelves are ideal for storing perishable items such as fresh vegetables and meats which require the lowest temperatures to preserve their taste and texture. Clear shelves allow cool air to circulate through the refrigerator. Keep soft cheeses and cured foods in a separate deli drawer for the perfect charcuterie platter.

Refrigerators also feature stainless steel or glass doors to protect the interior and facilitate cleaning. Some refrigerators have doors that are alarms that can be programmed to warn you when the fridge or freezer doors are closed for too long. You can program them to alert multiple people, and in escalating levels depending on your requirements. They can even be set to record and send temperature graphs remotely via text message or email.

Freestanding appliance thermometers are a cheap alternative to the built-in thermometers found in most refrigerators. It is crucial to monitor the temperature of the freezer and fridge frequently, particularly when there is an electrical failure or you have manually changed the temperature setting. Ideally, both the fridge and freezer should be set to 40 degrees Fahrenheit or below.

Capacity for Storage

The capacity of your refrigerator is an important factor when it comes to choosing the right model to meet your requirements. There are a variety of sizes to pick from, ranging from small refrigerators with a capacity of less than 15 cubic feet to large models that can accommodate more than 26 cubic feet. Think about your family's cooking style and the number of people living in your home to determine which size is best 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.

Look at the depth of the fridge in addition to the space. Some models are more shallow than others, which allows them to fit into tight spaces without taking up too much space under the counters. Cabinet-depth refrigerators are another option, having the depth being roughly the same as the typical kitchen cabinet front (though handles can protrude a little farther). These can be a good choice for areas where counter space is a problem, and they can also look more sleek than traditional refrigerators.

When you are shopping for a new refrigerator, ask about the level of noise and energy consumption. Many manufacturers offer quieter options for residential use, and certain models consume less energy than comparable models. You can find the energy consumption average of a particular model by examining the yellow Energy Guide label. Test the model by opening and refridgerator closing its doors.

A majority of modern refrigerators come with a pantry drawer, which is a full-width area with separate temperature controls that can be used to store many different objects. These drawers can be used to store party trays, wine and other items at a particular temperature. They can be programmed to hold wine, deli foods, and soft drinks, depending on the model.

Energy Efficiency

Refrigerators consume a lot of electricity. Therefore, it is important to select a refrigerator that is energy efficient. The good news is that refrigerators are becoming more energy efficient over the years. Insulation, motors, and magnetic door seals have all improved over time, meaning that a modern refrigerator consumes less energy than a model older in the same size. It is possible to cut down on the energy consumption of your refrigerator further by purchasing a highly energy efficient model. A refrigerator that has an Energy Star rating will use much less energy than a model that is at least ten years old.

Energy efficiency is especially important for consumers with limited access to electricity grids. Refrigerators for homes that are off grid are usually among the most expensive appliances. Their high energy consumption also means that they require huge systems of solar home systems that are not affordable for families earning less than $2 per day. The annual energy usage of a refrigerator is a key aspect to determine if it's economically feasible for consumers to buy and operate. (PATH and WHO 2013, McCarney et. al., 2012).

To understand how refrigerators function first, we must understand the basic refrigeration cycle. The refrigerator cools down by pushing a refrigerant fluid through an enclosed system. It starts as a liquid, and goes through the compressor, which compresses it to form the form of a vapor. This vapor flows into coils that are outside the smeg mini fridge and draws heat from it. It then cools down, and turns back to liquid. This process is repeated many times, keeping the food cool while the vapor flows through the coils.

Although refrigerators are among the most expensive appliances available to off-grid consumers, enhancing their energy efficiency makes them more affordable. By cutting down on the amount of energy they use, a refrigerator can be powered by a smaller SHS and reduce the overall system cost for consumers. The savings in energy are contingent on the size, design, and features of the refrigerator. Ice-makers and water dispensers through the door, for example are costly, but can increase the energy consumption of the refrigerator, which in turn increases the SHS needed to power it.

Maintenance

Regular maintenance and inspection can greatly improve the lifespan of your refrigerator. This can be done by checking the condenser coils, ice maker, defrost drain, and the gasket seal on the door to make sure it is in good condition. Cleaning and replacing water filter is also vital. These easy maintenance tasks will aid in prolonging the life of your refrigerator and also save money on your energy costs.

The easiest and most effective refrigerator refridgerator maintenance task is to wash the interior of your refrigerator frequently. This includes throwing away old food items, cleaning shelves and crispers, walls and interior of your refrigerator's doors. This can reduce the risk of foodborne illnesses and unpleasant odors. It is also recommended to regularly check the temperature of your refrigerator by using an electronic thermometer in your refrigerator. Refrigerators that aren't maintained may experience temperature fluctuations that can lead to food waste and higher electric bills.

It is also essential to clean the condenser coils of your refrigerator every two years to get rid of any dirt, dust, hair, grime and other debris that may have built up. These coils are located on the bottom or rear of your appliance. They are essentially radiator-like parts that help remove heat from your refrigerator. If they are dirty, they won't be able to disperse heat as effectively, and your refrigerator will use more energy to run.

Another thing to check often is the gasket in your refrigerator, which is designed to create an air-tight seal between the refrigerator and the ductwork in your home. This is essential to ensure that your fridge's contents remain cool However, over time, the seal can become worn down by greasy fingerprints, sticky syrups and dripping beverages. Wipe your fridge's seal with the help of a damp towel to keep it in good condition.

It is also a good idea to clean the drip tray, which is generally underneath the compressor unit of the refrigerator. This pan is used to store the water that comes from the defrost cycle and should be wiped down frequently to avoid the buildup of odors or mold.
