How to Choose a Refrigerator

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

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

Temperature Control

The proper temperature in the refrigerator ensures that food items are safe for storage which slows down the degradation of many foods due to spoilage. This is particularly important with foods like eggs and milk that can quickly rot at room temperature however, they remain stable in refrigerator temperatures. Refrigerators are also used to store pharmaceutical products like drugs and vaccines which lose effectiveness with time. Refrigerator monitoring systems can help ensure that an medical facility, laboratory or any other institution has the cold chain.

A refrigerator has an internal thermal insulator that helps keep its contents colder than the surrounding temperature. The heat pump moves warm air from outside the refrigerator to an insulated compartment where it cools to a very low temperature. The refrigerator also has a temperature control system that switches on the cooling system when its 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 specific function. The bottom shelves are perfect for perishables, such as fresh vegetables and meats that require the most low temperature to keep their texture and taste. Clearing the shelves allows cool air to circulate throughout the refrigerator. A separate deli drawer can be used to store soft cheeses and cured meats to create the perfect charcuterie board.

Refrigerators also have stainless steel or glass doors to protect the interior and allow for easy cleaning. Some refrigerators include a door-alarm that can be programmed. It will alert you if the fridge freezer is left open for too long. You can program them to alert multiple people and in escalating levels based on your needs. You can also set them to send temperature graphs by text or email.

Freestanding appliance thermometers are an inexpensive alternative to the built-in thermometers in the majority of refrigerators. It is essential to check the temperature of the fridge and freezer often, particularly when there is a power failure or if you manually altered the temperature setting. Ideally, outbuildings both the refrigerator and freezer should be set to 40 degrees Fahrenheit or lower.

Storage Capacity

The capacity of your refrigerator is a key factor in deciding on the model that will best suit your needs. There are a variety of sizes available that range from small models that have a capacity of less than 15 cubic feet to larger models that can hold more than 26 cubic feet. Think about your family's cooking style and the amount of people who live in your house to determine which size is best for you. For two people with a family of two, an average of between 11 and 13 cubic feet of refrigerator space is enough, while 18 to 22 cubic feet is recommended.

Check the depth of the fridge, in addition to the space. Some models are more deep than others to allow them to fit in tight spaces and not take up too much space under your counters. Cabinet-depth refrigerators are another option, having an overall depth that is the same as the standard front of a kitchen cabinet (though handles might protrude a bit further). These are a great choice for outbuildings homes with limited counter space. They can also look more sleek.

Find out about the refrigerator's energy usage and noise level when you are shopping. There are many manufacturers that offer quieter models for residential use, and certain models consume less electricity than similar models. Check the yellow Energy Guide label on appliances to find out about the typical energy consumption of a specific model. Test the model by opening and closing its doors.

The pantry drawer is usually an entire width of the refrigerator, with separate temperature controls. It can be used to store a variety things. These drawers can be used to store trays for parties, wine and other items at a particular 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. That's why it's crucial to have one that is energy efficient. The good news is that refrigerators have become more energy efficient over the years. Insulation, motors, fridge freezers and magnetic door seals have been improved over time, meaning that the latest refrigerator will consume less power than a previous model of the same size. It is possible to reduce the refrigerator's electricity consumption even more by purchasing an energy efficient model. A refrigerator with an Energy Star rating will use much less energy than a model ten years or older.

It is important to consider energy efficiency for consumers with limited access to electricity grids. For off-grid homes, refrigerators are typically among the most expensive appliances. Their high energy consumption also means that they require large amounts of solar home systems which aren't affordable for many families who earn less than $2 per day. The energy consumption per year of a refrigerator is a key element in determining whether it's cost-effective for consumers to purchase and operate. (PATH and WHO 2013, McCarney et. and., 2012).

To understand how fridges work, we start with the basic refrigeration cycle. A refrigerator cools by pushing a liquid refrigerant through a sealed system beginning as a liquid, then goes through a compressor which compresses the liquid into an vapour. This vapor then flows into coils located on the exterior of the refrigerator where it draws the heat from the fridge, settling down before turning back into a liquid. This process is repeated many times, ensuring that the food remains cold while the vapor flows through the coils.

Refrigerators are still one of the most expensive appliances that consumers who live off grid can buy however, improving their energy efficiency will make them more affordable. A refrigerator powered by a smaller SHS will be operated with less energy. This will reduce the total cost of the system. Energy savings vary depending on the size, design and features of a refrigerator. Ice-makers and water dispensers through the door, for instance, add cost, but can increase the energy consumption of the refrigerator, which can increase the amount of SHS required to run it.

Maintenance

Regular maintenance and inspections can significantly increase the life expectancy of your refrigerator. Check the condenser, defrost drain and ice maker. Also, look for seals on the door. Cleaning and replacing the water filter is also vital. Performing these simple maintenance tasks can help prolong the lifespan of your fridge and reduce your energy costs.

The simplest and most efficient refrigerator maintenance task is to clean the interior of your refrigerator regularly. This includes throwing out old food, wiping down shelves and crispers, walls, and the interior of the refrigerator's doors. This will reduce the risk of foodborne illnesses and unpleasant smells. A fridge thermometer is a good option to monitor the temperature of your fridge frequently. A fridge freezer on sale that is not properly maintained may have temperature fluctuations, which could result in food spoilage and an increase in your electric bill.

The condenser coils in your refrigerator should also be cleaned at least twice a year. This will eliminate any hair, outbuildings dirt, grime or other debris that has built up. These coils are located on the rear or bottom of your appliance and are basically radiator-like components that assist in helping remove heat from your refrigerator. These coils can't dissipate heat as efficiently when they are dirty. Your refrigerator will use more energy to run.

Check your refrigerator's seal, which is designed for an airtight seal between your fridge and the ductwork inside your home. It is important to ensure that your fridge's contents remain cold. However with time, the seal could be worn down by greasy fingerprints and sticky syrups. To keep your fridge's gasket in good shape, you should regularly wipe it down with a damp cloth.

It is also a good idea to clean the drip tray, which is generally beneath the compressor unit of the refrigerator. The pan is used for collecting the water from the refrigerator's defrost cycle. It should be cleaned frequently to prevent the growth of mold and unpleasant smells.
