How to Choose a Refrigerator

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

Certain refrigerators come with intelligent features, such as sensors and cameras. Some have touchscreens that allow you to watch videos, browse recipes, look up family calendars and shopping lists or even leave notes for family members.

Temperature Control

The ideal temperature for your refrigerator ensures food safety and will prevent spoilage. This is especially true for foods like eggs and milk which can quickly rot at room temperature however, they remain stable at refrigerator levels. Refrigerators are also extensively used to store pharmaceutical products like vaccines and medicines that lose efficacy over time. Refrigerator monitoring systems can ensure that an medical facility, laboratory or other establishment maintains an effective cold chain.

A refrigerator is equipped with an internal thermal insulator that helps keep its contents colder than the surrounding air. It makes use of a heat pump to move warm air out of the refrigerator into an insulated compartment, where it is extremely cold. The refrigerator has a control system which turns on the cooling system if its internal temperature exceeds the threshold set by the manufacturer. This prevents the formation of bacteria within the refrigerator.

Each compartment of the fridge is designed to serve a specific function. The lower shelves are ideal to store perishables such as fresh meats and vegetables that require the most low temperatures to preserve their taste and texture. Keeping the shelves clear allows cool air to circulate through the refrigerator. A separate drawer for deli can be used to store soft cheeses and cured meats to create the perfect charcuterie platter.

Refrigerators also come with stainless steel or glass doors to protect the interior and facilitate cleaning. Certain refrigerators also have a door alarm that can be programmed to warn you when the fridge or freezer doors are left open for too long. You can set them up to alert multiple people, and in escalating levels depending on your requirements. You can also set them to send temperature graphs via text or email.

Many refrigerators come equipped with thermometers however for those who don't, a stand-alone appliance thermometer can be a cheap method of monitoring the tall fridge sale and freezer temperature. It is crucial to monitor the temperature of the fridge and freezer frequently, particularly when there is an outage in power or you've manually changed the temperature setting. The ideal temperature for the refrigerator and freezer is 40 degrees Fahrenheit.

Capacity of Storage

The capacity of your refrigerator is an important aspect to consider when choosing the best model to meet your requirements. There are a variety of sizes to choose from including small models with a capacity less than 15 cubic foot to larger models that have a capacity of more than 26 cubic feet. To figure out the size you require, think about the cooking habits of your family and the number of people who live in your home. On average, 11 to 13 cubic feet of refrigerator space is enough for two people, whereas 18 to 22 cubic feet is recommended for three to four persons.

Check 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 room under the counters. Cabinet-depth refrigerators are a good alternative. Their depth is similar to the depth of a typical kitchen cabinet front, however the handles may protrude a little more. They are a great option for those with limited counter space. They also appear sleeker.

When shopping for a refrigerator, inquire about the level of noise and energy consumption. There are many manufacturers that offer quieter refrigerators for residential use. Some offer refrigerators with less energy consumption than comparable models. Look for the yellow Energy Guide label on appliances to find out about the typical energy consumption of the specific model. Also, test the model's operation by opening and closing the doors.

The majority of modern refrigerators have the pantry drawer, which is a full-width compartment with separate temperature controls that can be used to store many different items. These drawers are especially useful for storing party trays and wine, as they permit you to store them at specific temperatures. They can be programmed to store wine as well as deli food items, and soft drinks, depending on the model.

Energy Efficiency

Refrigerators consume a lot energy. It is therefore important to choose an energy-efficient refrigerator. Over time, refrigerators have become increasingly energy-efficient. Insulation, motors, and magnetic door seals have been improved over time, which means that the latest refrigerator will consume less energy than a model older in the same size. You can cut down on the electricity consumption of your refrigerator more by choosing a model that is highly energy efficient. A refrigerator that is Energy Star-rated will consume much less energy than an equivalent model 10 years old or older.

Efficiency in energy is crucial for consumers who have limited access to electricity grids. Refrigerators are typically one of the most expensive appliances for off-grid households and their large energy consumption means they require large solar home systems (SHS) which aren't affordable for families earning $2 per day or less. The annual energy usage of refrigerators is an important element in determining whether it's economically feasible for consumers to buy and operate. (PATH and refridgerator WHO 2013, McCarney and. al. 2012).

To understand how fridges function it is important to understand the basic refrigeration cycle. A refrigerator cools down by pushing refrigerant liquid through an enclosed system. It begins as a liquid, and goes through the compressor, which compresses it to form an vapor. This vapor flows into coils outside the refrigerator and draws heat out of it. It then cools before returning to liquid. This process repeats repeatedly to keep food cool as 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 can make them more affordable. A refrigerator powered by a smaller SHS will be powered by less energy. This will reduce the total cost of the system. Energy savings vary depending on the dimensions, design, and features of a refrigerator. For instance, ice-makers and through-the-door water dispensers can add cost, but can substantially increase the energy use which, in turn, increases the amount of SHS required to power it.

Maintenance

Regular maintenance and inspection can greatly increase the life expectancy of your refrigerator. Examine the condenser, the ice maker, and the defrost drain. Also, look for seals on the door. Cleaning and replacing the water filter is also important. Doing these simple tasks can extend the life of your fridge and save you money on energy bills.

The simplest and most efficient refrigerator maintenance task is to wash the inside of your refrigerator regularly. This includes throwing out old food and wiping down shelves as well as walls, crispers, and inside the doors of your freezer and refrigerator. This will eliminate unpleasant odors and reduce the chance of contracting food-borne illnesses. It is recommended to check regularly the temperature of your refrigerator by using a fridge thermometer. Unmaintained fridges may experience temperature fluctuations that can result in food waste and higher electric bills.

It is also essential to clean the condenser coils of your refrigerator twice a year to remove any dirt, hair, dust and other debris that could have built up. These coils, which are essentially radiators that remove heat from the refrigerator are located at the bottom or back of the appliance. They aren't able to disperse heat as efficiently when they're dirty. Your refrigerator will use more energy to run.

Another thing to check frequently is the gasket on your refrigerator that is designed to create an air-tight seal between the refrigerator and your home's ductwork. This is vital to ensure that the contents of your fridge stay cold However, over time, the seal may wear down from greasy fingerprints, sticky syrups and dripping drinks. Clean the seal of your fridge with a the help of a damp towel to keep it in good shape.

It is also a good idea to clean the drip tray, which is located generally beneath the compressor unit of the refrigerator. The pan is used to collect water that is drained from the defrost process and should be cleaned on a regular basis to avoid the buildup of odors and mold.
