15 Best Documentaries About Refridgerator 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. Some refrigerators have smart features, including sensors and cameras. Some refrigerators have touchscreens that let you watch videos, look up recipes, view family calendars and shopping lists or even leave notes for family members. Control of Temperature The right refrigerator temperature ensures food safety and will prevent spoilage. This is especially important for foods like eggs and milk which can quickly rot at room temperature, but remain stable in refrigerator temperatures. Refrigerators are also extensively used to store pharmaceuticals like vaccines and medicines that lose efficacy with time. Refrigerator monitoring systems are readily available to ensure that the medical facility or laboratory has the safety of its cold chain. A refrigerator has an internal thermal insulation to keep its contents cooler than the surrounding temperature. It makes use of the heat pump to move warm air from the refrigerator into an insulated compartment where it gets extremely cold. The refrigerator also has a control system that turns on the cooling system if its internal temperature is above a pre-set threshold. This prevents the formation of bacteria inside the refrigerator. Each refrigerator zone is designed to serve a specific purpose. The bottom shelves are great for perishables like fresh vegetables and meats that require the lowest temperature to keep their texture and taste. The shelves should be kept clear in order to allow cool air to circulate within the refrigerator. Store soft cheeses and cured food items in a separate deli drawer for the perfect charcuterie platter. Some refrigerators have glass or stainless steel door to safeguard the interior. They also make it easy to clean. Certain refrigerators also have door alarms that can be programmed to alert you if the doors to the freezer or fridge are left open for too long. You can set them to alert multiple people and in escalating levels based on your needs. You can also set them to send temperature graphs via email or text. Many refrigerators come equipped with thermometers however for those that don't, an independent appliance thermometer is an inexpensive way to check the fridge and freezer temperature. It is essential to check the temperature of the freezer and fridge often, particularly in the event of an electrical failure or you manually altered the temperature setting. Ideally, both the fridge and freezer should be set at 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, from small models with a capacity less than 15 cubic feet to larger models that have a capacity of more than 26 cubic feet. Take into consideration your family's cooking preferences and the number of people living in your house to determine which size is suitable for you. For two people with a family of two, an average of between 11 and 13 cubic foot of refrigerator space is sufficient and 18 to 22 cubic feet is recommended. Take a look at the depth of the fridge, in addition to the overall space. Some models are shallower than others, which allows them to fit in tight spaces without taking up too much space under the counters. Cabinet-depth refrigerators are another option, having an overall depth that is the similar to the standard kitchen cabinet front (though handles might protrude a bit further). These are a good option for homes with a limited counter space. They can also appear sleeker. Find out about the refrigerator's energy usage and noise level when shopping. Many manufacturers offer quieter refrigerators for homes. Others offer refrigerators with less electricity consumption than similar models. You can find the energy consumption average of a particular model by examining the yellow Energy Guide label. Also, test fridges uk by opening and closing the doors. A majority of modern refrigerators come with a pantry drawer, which is a full-width section with separate temperature controls that can be used for storing many different items. These drawers are ideal for storing party trays and wine, as they permit you to store them at certain temperatures. They can be programmed to hold wine, deli foods, and soft drinks, based on the model. Energy Efficiency Refrigerators use a lot of electricity. That's why it is important to have one that is energy efficient. The good news is that refrigerators have improved in energy efficiency over the years. Insulation, motors, as well as magnetic door seals have been improved over time, meaning that a newer fridge will use less power than an older one of the same size. It is possible to cut down on the power consumption of your refrigerator further by buying an energy efficient model. A refrigerator with an Energy Star rating will use much less energy than a model 10 years old or older. Energy efficiency is particularly important for consumers with limited access to electricity grids. Refrigerators are usually one of the most expensive appliances for homes that are not connected to the grid and their high energy consumption means that they require massive 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 economical for consumers to buy and run (PATH and WHO 2013; McCarney et al, 2012). We will begin by describing the basic refrigeration cycle. A refrigerator cools by pushing a liquid refrigerant through a sealed device: it starts as a liquid, and then is pushed through a compressor that compresses the liquid into a vapor. The vapor then flows through coils that are outside the fridge and draws heat out of it. It then cools and then returns to liquid. This process is repeated many times, keeping the food cold while the vapor moves through the coils. Although refrigerators are among the most expensive appliances for off grid consumers, increasing their energy efficiency makes them more affordable. By decreasing the amount of energy they use it is possible for a refrigerator to be powered by less energy and lower the overall system cost for consumers. Based on the size, style and features of the refrigerator, the savings on energy will differ. Ice-makers and water dispensers through the door, for instance can be costly, but can increase the energy consumption of the refrigerator, which increases the SHS needed to power it. Maintenance The life expectancy of a refrigerator could be greatly increased by regular maintenance and inspection. Examine the condenser, defrost drain and ice maker. Also, look for seals on the door. Cleaning and replacing water filters are equally important. These simple tasks can help you prolong the life of your refrigerator as well as save money on your energy costs. The simplest and most efficient refrigerator maintenance task is to clean the interior of your refrigerator regularly. This includes throwing away old food and wiping down shelves, crispers, walls, and the inside of the doors of your refrigerator and freezer. This will help prevent unpleasant odors and lower the chance of contracting food-borne illnesses. It is recommended to check regularly the temperature of your refrigerator using a fridge thermometer. A fridge that is not properly maintained can experience temperature fluctuations, which could cause food spoilage and a higher electricity bill. It is also important to clean the condenser coils in your refrigerator twice a year to get rid of any dirt, hair, dust and other debris that may have accumulated. These coils, which are essentially radiators that help to remove heat from the refrigerator are located at the bottom or back of your appliance. These coils can't dissipate heat as efficiently when they are dirty. Your refrigerator will use more energy to run. Another thing you should be checking often is the gasket in your refrigerator, which is designed to create an air-tight seal between your refrigerator and your home's ductwork. It is important to keep the contents of your fridge cold. However with time, the seal may be damaged by greasy fingerprints and sticky syrups. Clean 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 usually underneath the compressor unit of the refrigerator. This pan is used to store the water that comes from the defrost cycle and should be cleaned regularly to avoid the accumulation of odors and mold.
