How to Choose a Refrigerator Refrigerators sometimes called fridges are kitchen appliances that keep food and beverages cold They are commonly used in homes and in offices hotels and college dorm rooms Some refrigerators have smart features such as sensors and cameras Certain refrigerators come with touchscreens that let you view videos and search for recipes look up family calendars or shopping lists or even write notes Temperature Control A proper temperature in the refrigerator will keep food safe and prevent loss This is especially important for foods like eggs and milk which are susceptible to rotting at room temperature but remain stable in refrigerator temperatures Refrigerators are also extensively used to store pharmaceutical products like drugs and vaccines that become less effective as time passes Monitoring systems for refrigerators can help ensure that the medical facility laboratory or other institution has a cold chain A refrigerator is equipped with an internal thermal insulation to keep its contents colder than the surrounding environment The heat pump is used to move warm air from the outside of the refrigerator into an insulated compartment where it cools to a very low temperature The refrigerator has a control system that turns on the cooling system when its internal temperature is higher than a predetermined threshold This stops the growth of bacteria within the refrigerator Each of the refrigerator zones is designed for a different purpose The bottom shelves are great for perishables such as fresh meats and vegetables that require the minimum temperature to keep their texture and taste The shelves should be kept clear in order to allow cool air to circulate in the refrigerator Store soft cheeses and cured items in a separate drawer for deli to create the perfect charcuterie platter Some refrigerators have doors made of stainless steel or glass to protect the interior They also make it easy to clean Some refrigerators have a door alarm that can be programmed to notify you when the fridge or freezer doors are closed for too long You can set them up to notify multiple people and in increments based on your needs You can set them up to send temperature graphs by text or email Freestanding appliance thermometers are a cheap alternative to the builtin thermometers found in the majority of refrigerators It is essential to check the temperature of the freezer and fridge often especially if there has been an outage in power or you manually altered the temperature setting Ideal temperature for both the refrigerator and freezer is 40 degrees Fahrenheit Storage Capacity The capacity of your refrigerator is an important aspect to consider when selecting the model that is most suitable for 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 larger models that accommodate more than 26 cubic feet To determine which size you require think about your familys cooking habits and the number of people in your home On average 1113 cubic feet of refrigerator space is adequate for two people 18 to 22 cubic feet is recommended for three to four people In addition to assessing the total interior space take a look at the depth of your fridge Some models are shallower than others which allows them to fit into small spaces without taking up too much space under your counters Cabinetdepth refrigerators are a good option Their depth is similar to the depth of a typical kitchen cabinet but the handles may extend a little further They are a great choice for areas where counter space is at a premium and they can also look sleeker than traditional fridges Be sure to inquire about the refrigerators energy consumption and noise level when shopping There are many manufacturers that offer quieter refrigerators suitable for residential use Some offer refrigerators with less electricity consumption than similar models You can find the energy consumption average of a model by checking the yellow Energy Guide label Also test the models operation by opening and closing the doors The pantry drawer is typically the largest section of the refrigerator that has separate temperature controls It can be used to store a variety things These drawers are ideal to store party trays and wine since they allow you to keep them at a specific temperature They can be programmed to store wine as well as deli food items and soft drinks based on the model Energy Efficiency Refrigerators consume a lot electricity Therefore it is important to select a refrigerator that is energy efficient The good news is that refrigerators have become more energy efficient over the years Insulation motors as well as magnetic door seals have all improved over time so a newer fridge will use less energy than a previous model of the same size You can reduce the electricity consumption of your refrigerator even more by purchasing one that is energy efficient A refrigerator that is Energy Star certified will consume much less energy than an equivalent model that is ten years old or older It is essential to consider energy efficiency for consumers with limited access to electricity grids Refrigerators are usually one of the most expensive appliances for households that are off grid and their high energy consumption means that they require large solar home systems SHS that are not affordable for families earning less than 2 per day The annual energy consumption of a refrigerator is therefore a key factor in determining whether it is affordable for consumers to purchase and maintain PATH and WHO 2013 McCarney et al 2012 To understand how fridges function it is important to understand the fundamental refrigeration cycle A refrigerator cools itself by pushing a refrigerant fluid through a sealed system It begins as a fluid then goes through the compressor that makes it compress into an vapor This vapor then flows into coils that are located on the outside of the fridge where it draws heat from the fridge cooling down before returning to the liquid This process is repeated several times keeping food cold while the vapor moves through the coils While refrigerators are among the most expensive appliances for off grid consumers enhancing their energy efficiency makes them more affordable A refrigerator that is powered by a smaller SHS can be powered with less energy This will lower total system cost The savings in energy are contingent on the dimensions design and features of a refrigerator For instance icemakers and throughthedoor water dispensers add cost but can significantly increase the refrigerators energy use which in turn increases the amount of SHS required to power it Maintenance The life span of a refrigerator could be greatly improved with regular maintenance and inspection This can be accomplished by checking the condenser coils the ice maker the defrost drain as well as the gasket seal on the door to make sure that it is in good working order Cleaning and replacing water filter is also important These simple maintenance tasks can extend the lifespan of your fridge and reduce your energy costs The simplest and most efficient refrigerator maintenance task is to wash the inside of your refrigerator frequently This includes throwing out old food items and wiping down shelves as well as walls crispers and inside the doors of your freezer and refrigerator This can reduce the risk of foodborne illnesses and unpleasant smells It is also recommended to periodically check the temperature of your refrigerator with the help of a thermometer for your fridge Refrigerators that are not maintained can experience temperature fluctuations that could lead to food waste and higher electricity costs The condenser coils in your refrigerator should be cleaned at least twice a year This will eliminate any hair dirt grime or other debris that may have accumulated The coils are located at the bottom or back of your appliance Theyre basically radiatorlike components that assist in helping remove heat from your refrigerator They arent able to disperse the heat as effectively when they are dirty Your refrigerator will use more energy to run Check your refrigerators seal which is designed to provide an airtight seal between the fridge and the ductwork in your home It is essential to keep your fridges contents cold However with time the seal could be damaged by greasy fingerprints and sticky syrups Clean your fridges seal with a damp towel to keep it in good condition It is also an ideal idea to regularly clean the drip pan which is normally situated under the compressor unit This pan is used to collect water that is drained from the defrost process and should be cleaned on a regular basis to avoid the accumulation of odors or mold
