How to Choose a Refrigerator Refrigerators are kitchen appliances used to keep food and drinks cold. They're used at home and in hotels, offices and college dorm rooms. Certain refrigerators come with smart features, including cameras and sensors. Certain refrigerators come with touchscreens that allow you to watch videos and search for recipes, browse family calendars, or shopping lists, or even write notes. Temperature Control The correct refrigerator temperature ensures food is safe to store which slows down the degradation of many foods due to spoilage. This is especially true for food such as eggs and milk which are susceptible to rotting at room temperature however, they remain stable in refrigerator temperatures. Refrigerators are also extensively used to store pharmaceutical products such as vaccines and drugs which lose effectiveness as time passes. Refrigerator monitoring systems are in place to help ensure an medical laboratory or medical facility maintains the safety of its cold chain. A refrigerator has an internal thermal insulation to keep its contents colder than the surrounding environment. The heat pump transports warm air from outside the refrigerator to an insulated compartment, from which it cools down. The refrigerator has a controlled system that activates the cooling system if its internal temperature is higher than a preset threshold. This prevents bacteria from forming within the refrigerator. Each compartment of the fridge is specifically designed to serve a certain purpose. The bottom shelves are ideal to store perishables such as fresh vegetables and meats which require the minimum temperatures to preserve their taste and texture. The shelves should be kept clean to allow cool air to circulate in the refrigerator. Store soft cheeses and cured foods in a separate drawer for deli to create the perfect charcuterie platter. Refrigerators also have stainless steel or glass doors to protect the interior and allow for easy cleaning. Some refrigerators have doors that are alarms that can be programmed to notify you when the doors to the freezer or fridge are closed for too long. They can be programmed to notify multiple people in escalating tiers depending on your needs. They can even be set to record and send temperature graphs remotely via email or text. Most refrigerators have built-in thermometers however for those that don't, a freestanding appliance thermometer is a cost-effective way to check the temperature of your freezer and fridge. It is important to monitor the temperature of your freezer and refrigerator frequently, particularly after a power outage or if the temperature settings are altered manually. The ideal temperature for both the freezer and refrigerator is 40 degrees Fahrenheit. Capacity for Storage The capacity of your refrigerator is a key factor in deciding on the model that best suits your requirements. There are a variety of sizes to choose from, ranging from tiny refrigerators with a capacity of less than 15 cubic feet, to large models that accommodate more than 26 cubic feet. To figure out the size you require, think about your family's cooking habits and the number of people in your home. On average, 11 to 13 cubic feet of refrigerator space is enough for two people, while 18 to 22 cubic feet are recommended for three to four people. In addition to considering the space inside take a look at the depth of your refrigerator. Some models are shallower than others, which allows them to fit into small spaces without taking up too much room under the counters. Cabinet-depth refrigerators are another option, with a depth that is roughly the same as the standard 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 also appear more modern. Ask about the refrigerator's energy usage and noise level when shopping. There are many manufacturers that provide quieter refrigerators for residential use. Some offer refrigerators with less electricity consumption than similar models. You can find out the energy usage of a model by checking the yellow Energy Guide label. Also, test a model's operation by opening and closing the doors. The pantry drawer is typically an entire width of the refrigerator that has 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 hold wine, deli foods, and soft drinks, depending on the model. Energy Efficiency Refrigerators consume a lot of energy. That's why it is important to have one that is energy efficient. refrigerator Frydge is that refrigerators are becoming more energy efficient over the years. The insulation, motors, and magnetic door seals of a newer refrigerator consume less energy than a refrigerator that is similar in size. It is possible to cut down on the power consumption of your refrigerator further by buying an energy efficient model. A refrigerator that is Energy Star rated will consume much less energy than a comparable model that is ten years old or older. It is essential to consider energy efficiency for consumers with limited access to electricity grids. Refrigerators for homes that are off grid are typically among the most expensive appliances. Their large energy consumption also means that they require large systems of solar home systems that are out of reach for many families who earn less than $2 per day. The energy consumption per year of a refrigerator is a key factor to determine whether it's economically feasible for consumers to purchase and operate. (PATH and WHO 2013, McCarney and. al., 2012). We will start by explaining the basic refrigeration process. A refrigerator cools down by pushing refrigerant liquid through a sealed system. It starts out as a liquid, and then goes through the compressor, which reduces it to the form of a vapor. This vapor then flows into coils located on the exterior of the refrigerator where it draws the heat from the fridge, then cooling down before returning to the liquid. This process is repeated over and over again to keep food cool as the vapor flows through the coils. Refrigerators are one of the most expensive appliances that consumers off-grid can purchase however, improving their energy efficiency can make them more affordable. A refrigerator powered by a smaller SHS can be powered with less energy. This can lower the total cost of the system. Depending on the size, style, and features of the refrigerator, energy savings will differ. Water dispensers and ice makers through the door, for example are costly however they can also increase the energy consumption of the refrigerator, which can increase the amount of SHS required to power it. Maintenance Regular maintenance and inspection can greatly improve the lifespan of your refrigerator. Check the condenser unit, the ice maker, and the defrost drain. Also, check the seals on the door. Cleaning and replacing the water filter is also vital. These simple tasks can aid in prolonging the life of your refrigerator and save money on your energy bills. Cleaning the inside of your fridge regularly is the simplest and most effective way to maintain it. This includes throwing out old food, wiping down shelves and crispers, walls and the inside of your refrigerator's doors. This will lower the chance of contracting foodborne illness and unpleasant odors. A refrigerator thermometer is a good option to monitor the temperature of your fridge frequently. A fridge that is not properly maintained may be subject to temperature fluctuations that could result in food spoilage and a higher electricity bill. The condenser coils in your refrigerator should be cleaned at least twice a year. This will remove any dirt, grime, hair or other debris that has built up. These coils, which are basically radiators that help remove heat from your refrigerator, are located at the bottom or rear of your appliance. These coils can't dissipate heat as efficiently when they are dirty. Your refrigerator will consume more energy to run. Check your refrigerator's seal that is designed to create an airtight seal between the fridge and the ductwork that runs through your home. It is important to keep your fridge's contents cold. However, over time, the seal may be worn down by sticky and greasy fingerprints. syrups. Wipe your fridge's seal with a damp towel to keep it in good shape. It is also a good idea, to clean the drip tray, which is usually under the compressor unit of the refrigerator. This pan is used to collect water that is drained from the defrost process, and it should be cleaned frequently to avoid the buildup of odors or mold.
