How to Choose a Refrigerator Refrigerators are kitchen appliances used to keep food and beverages cold They are used in homes, offices, hotels and college dorms Certain refrigerators come with smart features, such as sensors and cameras Some refrigerators have touchscreens that allow you to watch videos, look up recipes, look up family calendars and shopping lists, or even leave notes for family members Temperature Control The ideal temperature for your refrigerator will ensure food safety and will prevent loss This is especially important for food such as eggs and milk that can quickly rot at room temperature however, they remain stable at refrigerator levels Refrigerators can also be used to store pharmaceuticals such as drugs or vaccines that lose their efficacy with time Refrigerator monitoring systems are readily available to ensure that the medical facility or laboratory maintains a safe cold chain The internal thermal insulator of a refrigerator keeps its contents cooler than the surrounding air The heat pump is used to move warm air from outside the refrigerator to an insulated compartment, where it cools to a very low temperature The refrigerator has a control system that activates the cooling system if its internal temperature is higher than a predetermined threshold This prevents the growth of bacteria within the refrigerator Each compartment of the fridge is specifically designed to serve a certain purpose The lower shelves are ideal for perishables, such as fresh vegetables and meats that require the lowest temperature to keep their texture and flavor Clear shelves allow cool air to circulate throughout the refrigerator A separate deli drawer can be used to store soft cheeses and cured foods for the perfect charcuterie platter Refrigerators also have stainless steel or glass doors to protect the interior and allow for easy cleaning Some refrigerators come with a door alarm that can be programmed It will notify you if the fridge or freezer is left open for too long You can set them to notify multiple people and in escalating levels based on your requirements You can also set them to send temperature graphs via email or text Most refrigerators have built-in thermometers, but for those who don't, a stand-alone appliance thermometer is a cost-effective way to check the temperature of the freezer and refrigerator It is important to check the temperature of the freezer and fridge frequently, particularly when there is an electrical failure or you manually altered the temperature setting Ideally, both the refrigerator and freezer should be set at 40 degrees Fahrenheit or lower Capacity of Storage The capacity of your refrigerator is a key factor when choosing the model that will best suit your requirements There are many sizes available including small models with a capacity less than 15 cubic feet to large models that have a capacity of more than 26 cubic foot Think about your family's cooking style and the amount of people who live in your home to figure out which size is suitable for you On average, 11 to 13 cubic feet of refrigerator space is adequate for two people, whereas 18 to 22 cubic feet are recommended for three to four people In addition to assessing the total interior space, look at the depth of your fridge Certain models are deeper than others to allow them to fit in small spaces and not take up too much space under your counters Cabinet-depth refrigerators are a good option Their depth is comparable to that of a standard kitchen cabinet, but the handles can extend a bit more These are a good option for homes with limited counter space They can also look sleeker When shopping for a refrigerator, inquire about the level of noise and energy consumption There are many manufacturers that offer quieter refrigerators suitable for homes Other refrigerators have less energy consumption than comparable models You can find the energy consumption average of a particular model by examining the yellow Energy Guide label Also, test the model's operation by opening and closing the doors A majority of modern refrigerators come with the pantry drawer It is a full-width section with separate temperature controls that can be used for storing a variety of items These drawers are ideal to store party trays and wine, since they allow you to store them at certain temperatures Based on the model, these drawers may have pre-programmed settings for wines, deli meats and soft drinks Energy Efficiency Refrigerators consume a lot of electricity Therefore, it is important to select a refrigerator that is energy efficient Over time refrigerators have become more energy efficient Insulation, motors, and magnetic door seals have been improved over time, meaning that the latest refrigerator will consume less energy than a model older in the same size You can reduce the electricity consumption of your refrigerator more by choosing one that is energy efficient A refrigerator that is Energy Star rated will use a lot less energy than a comparable model ten years old or more Energy efficiency is especially important for consumers who have limited access to electricity grids Refrigerators are often among the most costly appliances for homes that are not connected to the grid, and their high energy consumption means that they require huge solar home systems SHS which aren't affordable for many families earning less than 2 per day The annual energy usage of refrigerators is an important factor to determine whether it's economically feasible for consumers to buy and operate PATH and WHO 2013 McCarney et al, 2012 We'll begin by explaining the basic refrigeration cycle A refrigerator cools down by pushing refrigerant liquid through a sealed system It begins as a fluid, then goes through the compressor, which reduces it to a vapour This vapor then flows into coils located on the exterior of the fridge where it draws heat from the fridge, cooling down before returning to the liquid This process is repeated over and over again, keeping food cold as the vapor circulates through the coils While refrigerators are among the most expensive appliances for off-grid consumers, improving their energy efficiency makes them more affordable A refrigerator that is powered by a smaller SHS could be powered by less energy This will reduce the total cost of the system Depending on the size, style, and features of the refrigerator, the energy savings will vary Ice makers and water dispensers that are located through the door, for instance can be costly however they can also increase the energy consumption of the refrigerator, which in turn increases the amount of SHS required to run it Maintenance Regular maintenance and inspection can significantly increase the lifespan of your refrigerator Check the condenser, defrost drain and ice maker Also, look for seals on the door In addition, cleaning and replacing water filters is equally important These easy maintenance tasks will aid in prolonging the life of your refrigerator and also save money on your energy costs The simplest and most efficient refrigerator maintenance task is to clean the inside of your refrigerator frequently This means throwing away old food items and wiping the shelves and crispers, walls and even inside the doors of your refrigerator and freezer https//wwwfrydgeuk/ can reduce the risk of foodborne illnesses and unpleasant odors A fridge thermometer is recommended for checking the temperature of your refrigerator regularly Refrigerators that aren't maintained are prone to temperature fluctuations that could result in food waste and higher electricity costs The condenser coils of your refrigerator should also be cleaned twice a year This will get rid of any dirt, grime, hair or other debris that may have accumulated These coils, which are actually 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're dirty Your refrigerator will consume more energy to run Another thing to check frequently is the gasket on your refrigerator that is designed to create an airtight seal between your fridge and your home's ductwork This is vital to ensure your fridge's contents stay cold But over time, the seal could wear down by greasy fingerprints, sticky syrups, and dripping drinks 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 located generally underneath the compressor unit of the refrigerator The drip pan is responsible to collect water from the defrost cycle of the refrigerator It should be cleaned frequently to prevent the development of mold and unpleasant odors
