How to Choose a Refrigerator Refrigerators are kitchen appliances used to keep food and beverages cold. They are commonly used in homes, offices in hotels, restaurants and college dorms. Certain refrigerators come with sophisticated features such as cameras and sensors. 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 proper temperature in the refrigerator keeps foods safe for storage, slowing the deterioration of many food items due to spoilage. This is particularly important with food items like eggs and milk that quickly turn rotten at room temperature, but remain stable in refrigerator temperatures. Refrigerators can also be used to store pharmaceuticals, such as vaccines or drugs that lose their efficacy with time. Refrigerator monitoring systems are in place to help ensure a medical facility or laboratory keeps a safe cold chain. A refrigerator has an internal thermal insulator that helps keep its contents colder than the surrounding temperature. The heat pump transports warm air from outside the refrigerator to an insulated compartment, from which it becomes very cool. The refrigerator is equipped with a control system that turns on the cooling system when its internal temperature is higher than a preset threshold. This prevents bacteria from forming in the refrigerator. Each of the refrigerator zones is designed to serve a distinct purpose. The lower shelves are perfect for storing perishable items such as fresh meats and vegetables, which require the minimum temperatures to preserve their flavor and texture. Clearing the shelves allows cool air to circulate throughout the refrigerator. Keep soft cheeses and cured items in a separate drawer for deli for the perfect charcuterie tray. Certain refrigerators have doors made of stainless steel or glass to safeguard the interior. They also make it easy to clean. Some refrigerators have door alarms that can be programmed to notify you if the freezer or fridge doors are left open for too long. You can set them to notify multiple people and in escalating levels depending on your requirements. They can be configured to record temperature and send graphs remotely via text or email. Freestanding appliance thermometers are a cheap alternative to the built-in thermometers found in the majority of refrigerators. It's important to check the temperature of your freezer and refrigerator frequently, particularly during power outages or if temperature settings are changed manually. The ideal is that both the fridge and freezer should be set to 40 degrees Fahrenheit or below. Capacity of Storage The capacity of your refrigerator is an important factor in deciding on the model that will best suit your requirements. There are many sizes to pick from, ranging from small refrigerators that can hold a volume of less than 15 cubic feet to larger models that hold over 26 cubic feet. To determine which size you require, think about your family's cooking habits and the number of people who live in your home. For two people the average of 11-13 cubic foot of refrigerator space is enough for a household of two. For a family of three, 18 to 22, cubic feet is recommended. Check the depth of the fridge in addition to the overall space. Some models are more deep than others to allow them to fit in small spaces and not take up too much space under your counters. Cabinet-depth fridges are also an alternative. Their depth is similar to the depth of a typical kitchen cupboard front, though handles may protrude a little further. These are a great choice for homes with a limited counter space. They can also appear more modern. Ask about the energy consumption of the refrigerator and noise level when shopping. There are many manufacturers that offer quieter models for residential use, while others offer refrigerators that use less energy than similar models. You can find out the energy usage of a particular model by examining the yellow Energy Guide label. Also, test a model's operation by opening and closing the doors. The pantry drawer is typically the largest section of the refrigerator with separate temperature controls. It can be used to store a variety items. These drawers can be used to store trays for parties wine, other food items and more at a certain temperature. Based on the model, these drawers could include pre-programmed settings to store wines, deli meats and soft drinks. Energy Efficiency Refrigerators use a lot of energy. That's why it is important to choose one that is energy efficient. Over the years refrigerators have become more energy-efficient. Insulation, motors, as well as magnetic door seals have all improved over time, so a modern refrigerator consumes less energy than a previous model of the same size. It is possible to reduce the refrigerator's electricity consumption even more by purchasing an energy efficient model. A refrigerator that is Energy Star certified will use less energy than a comparable model that is ten years old or more. It is crucial to think about energy efficiency for those who have limited access to electricity grids. For off-grid homes, refrigerators are usually among the most expensive appliances. Their high energy consumption also implies 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 annual energy usage of a refrigerator is a key factor to determine whether it's economically feasible for consumers to buy and operate. (PATH and WHO 2013 ). McCarney et. and. 2012). To understand how fridges work first, we must understand the basic refrigeration cycle. A refrigerator cools by pushing liquid refrigerant through a sealed unit that begins as a liquid, and then passes through a compressor that compresses the liquid to form the form of a vapor. This vapor is then pumped into coils that are located on the outside of the fridge, where it draws the heat from the fridge, cooling down before turning back into a liquid. This process is repeated several times, keeping food cold while the vapor moves through the coils. Refrigerators are still one of the most expensive appliances that consumers who are not connected to the grid can purchase, but improving their energy efficiency can make them more affordable. A refrigerator powered by a smaller SHS could be powered by less energy. This will lower total system cost. Energy savings differ based on the size, design, and features of the refrigerator. For instance, ice makers and through-the-door water dispensers can add cost, but they can also significantly increase the refrigerator's energy consumption and, in turn, increase the amount of SHS required to power it. Maintenance Regular maintenance and inspection can significantly increase the life expectancy of your refrigerator. Check the condenser, defrost drain and ice maker. Also, look for seals on the door. Cleaning and replacing the water filter is also important. These simple tasks can help you prolong the life of your refrigerator and also save money on your energy bills. Cleaning fridges www.frydge.uk of your refrigerator 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 interior of the refrigerator's doors. This will eliminate unpleasant odors as well as reduce the risk of food-borne illnesses. A refrigerator thermometer is a good option to monitor the temperature of your fridge regularly. Refrigerators that aren't maintained may experience temperature fluctuations that could cause food waste and higher electric bills. The condenser coils inside your refrigerator should also be cleaned every two years. This will eliminate any dirt, grime, hair or other debris that has built up. These coils, which are essentially radiators that remove heat from your refrigerator, are located at the bottom or back of your appliance. When these are dirty, they aren't able to release heat as efficiently and your refrigerator will use more energy to run. Another thing to be able to check often is the gasket in your refrigerator that is designed to create an air-tight seal between your refrigerator and your home's ductwork. It is important to keep your fridge's contents cool. However with time, the seal can be damaged by greasy fingerprints and sticky syrups. Clean the seal of your fridge with a a damp towel to keep it in good condition. In the end, it's a good idea to clean the drip pan, which is typically situated under the compressor unit. This pan is used for collecting the water from the refrigerator's defrost process. It is recommended to clean it regularly to prevent the development of mold and unpleasant odors.
