How to Choose a Refrigerator

Refrigerators are kitchen appliances that are used to keep food and beverages cold. They are found in offices, homes hotels, and college dorms.

Some refrigerators are equipped with smart features, including sensors and cameras. Some have touchscreens that let you watch videos, search for recipes, browse family calendars and shopping lists, or even leave notes for family members.

Control of Temperature

The right refrigerator temperature will ensure food safety and avoid the food from spoiling. This is especially important for food items such as eggs and milk, which can quickly rot when exposed temperatures that are not ideal but stay stable in the refrigerator. Refrigerators are also widely used to store pharmaceutical products like drugs and vaccines that become less effective as time passes. Refrigerator monitoring systems are readily available to ensure that the medical facility or laboratory has an appropriate cold chain.

The internal thermal insulator of a refrigerator keeps its contents cooler than surrounding air. The heat pump moves warm air from outside the refrigerator to an insulated compartment, where it cools down. The refrigerator also has a controlled system that activates the cooling system when the internal temperature is above the pre-set threshold. This stops the growth of bacteria within the refrigerator.

Each refrigerator zone is designed to serve a distinct function. The lower shelves are ideal for storing perishable items such as fresh meats and vegetables that require the minimum temperatures to preserve their flavor and texture. The shelves must be kept clean to allow cool air to circulate through the refrigerator. A separate drawer for deli can be used to store soft cheeses and cured meats for the perfect charcuterie board.

Refrigerators also have doors made of stainless steel or glass to protect the interior and facilitate cleaning. Certain refrigerators also have doors that are alarms that can be programmed to warn you when the doors to the freezer or fridge are closed for too long. They can be set to alert multiple individuals and in escalating levels based on your needs. They can be configured to record and send temperature graphs remotely via text or email.

Freestanding appliance thermometers can be a cost-effective alternative to the built-in thermometers in most refrigerators. It is important to monitor the temperature of the freezer and refrigerator often, especially after a power outage or when temperature settings are altered manually. The ideal is that both the fridge and freezer should be set to 40 degrees Fahrenheit or below.

Storage Capacity

The capacity of your refrigerator is an important factor in deciding on the model that is most suitable for your requirements. There are many sizes available including small models with a capacity less than 15 cubic feet to large models that can hold more than 26 cubic feet. To determine which size you need, consider your family's cooking habits and the number of people in your home. For two people, an average of 11-13 cubic foot of refrigerator space is enough for a household of two. For a family of three, 18 to 22 cubic feet is recommended.

In addition to assessing the overall space of your kitchen take a look at the depth of your refrigerator. Some models are more shallow than others, which allows them to fit into tight spaces without taking up too much room under the counters. Cabinet-depth refrigerators are another option, and have a depth that is roughly the similar to the typical front of a kitchen cabinet (though handles can protrude a little more). They are a great option for homes with a limited counter space. They can also appear sleeker.

Ask about the energy consumption of the refrigerator and the level of noise when you are shopping. Many manufacturers offer quieter refrigerators suitable for refridgerator residential use. Others offer refrigerators with less electricity consumption than similar models. You can find out the energy usage of a particular model by examining the yellow Energy Guide label. Test the appliance by opening and closing its doors.

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

Energy Efficiency

Refrigerators consume a lot energy. It is therefore important to select a refrigerator that is energy efficient. As time has passed, refrigerators have become increasingly energy-efficient. The insulation, motors and magnetic door seals of a modern refrigerator use less energy than an older fridge similar in size. It is possible to cut down on the refrigerator's electricity consumption even more by purchasing an energy efficient model. A refrigerator that is Energy Star rated will use less energy than a comparable model ten years old or more.

Energy efficiency is particularly important for those who have no access to the grid for electricity. Refrigerators are typically among the most costly appliances for households that are off grid, and their large energy consumption means they require huge solar home systems (SHS) that are not affordable for many families making $2 per day or less. The annual energy consumption of a refrigerator is therefore a key aspect in determining if it is economical for consumers to purchase and maintain (PATH and WHO 2013; McCarney et al, 2012).

To understand how refrigerators function, we start with the basic refrigeration cycle. A refrigerator cools by pushing liquid refrigerant through a sealed unit that begins as a liquid and passes through a compressor that compresses the liquid to form a vapor. This vapor is then pumped into coils on the outside of the fridge where it draws the heat from the fridge, settling down before turning back into a liquid. This process is repeated several times, ensuring that the food remains cold while the vapor moves through the coils.

Refrigerators remain one of the most expensive appliances that consumers off-grid can purchase but enhancing their energy efficiency can make them more affordable. A refrigerator powered by a smaller SHS can be powered with less energy. This will reduce the total system cost. Energy savings differ based on the size, style and other features of a refrigerator. For example, ice-makers and through-the-door water dispensers add cost, but they can also significantly increase the refrigerator's energy use, which in turn increases the SHS required to power it.

Maintenance

The lifespan of a refrigerator refridgerator can be significantly improved by regular maintenance and inspection. Examine the condenser, defrost drain and ice maker. Also, check the seals on the door. In addition, cleaning and changing water filters is essential. Performing these simple maintenance tasks can prolong the life of your refrigerator and also save you money on energy bills.

Cleaning the interior of your refrigerator regularly is the most efficient and efficient method to keep it clean. This means throwing away old food items, wiping down shelves and crispers, walls, and the inside of your refrigerator's doors. This can reduce the chance of contracting foodborne illness and unpleasant smells. It is also recommended to regularly check the temperature of your refrigerator using an electronic thermometer in your refrigerator. A fridge that is not properly maintained could have temperature fluctuations, which can lead to food spoilage as well as a higher electric bill.

It is also crucial to clean the condenser coils in your refrigerator at least twice per year to remove any dirt, dust, hair, grime, and other debris that may have built up. These coils are located on the rear or bottom of your appliance and are basically radiator-like components that help remove heat from your refrigerator. These coils can't dissipate the heat as efficiently if they are dirty. Your refrigerator will require more energy to run.

Another thing to check regularly is your refrigerator's gasket that is designed to form an airtight seal between the fridge and your home's ductwork. This is vital to ensure your fridge's contents remain cold But over time, the seal could wear down from greased fingerprints, sticky syrups, and dripping drinks. To keep the gasket of your refrigerator in good shape, you should frequently clean it with the help of a damp cloth.

Lastly, it is a good idea to regularly clean the drip pan, which is normally located beneath the compressor unit. This pan is used to collect the water that is drained from the refrigerator's defrost process. It is recommended to clean it regularly to avoid the growth of mold and unpleasant smells.
