How to Choose a Refrigerator Refrigerators (sometimes called a fridge) are kitchen appliances that keep food and beverages cold. They are used at home as well as in hotels, offices and college dorm rooms. Some refrigerators are equipped with smart features like sensors and cameras. Certain refrigerators come with touchscreens that allow you to watch videos or search for recipes, view family calendars, and shopping lists or leave notes. Control of Temperature The ideal temperature for your refrigerator ensures food safety and will prevent loss. This is especially true for food such as eggs and milk that can quickly rot at room temperature but remain stable at refrigerator levels. Refrigerators are also extensively used to store pharmaceuticals such as vaccines and drugs that become less effective over time. Refrigerator monitoring systems can help ensure that the medical facility, laboratory or other institution has a cold chain. A refrigerator is equipped with an internal thermal insulator that helps keep its contents cooler than the surrounding air. The heat pump transports warm air from outside the refrigerator into an insulated compartment, where it becomes very cool. The refrigerator also has a control system that switches on the cooling system when the internal temperature exceeds the threshold set by the manufacturer. This prevents the formation of bacteria in the refrigerator. Each refrigerator zone is designed to serve a distinct purpose. The bottom shelves are great for perishables, such as fresh vegetables and meats that require the minimum temperature to preserve their texture and taste. The shelves must be kept clear in order to allow cool air to circulate within the refrigerator. Keep soft cheeses and cured items in a separate deli drawer for the perfect charcuterie tray. Certain refrigerators have glass or stainless steel door to protect the interior. They also make it easy to clean. Some refrigerators also include doors that are alarms that can be programmed to warn you when the fridge or freezer doors are closed for too long. They can be programmed to notify multiple people and in escalating levels based on your needs. They can even be set to record temperature and send graphs remotely via text or email. Freestanding appliance thermometers are an inexpensive alternative to the built-in thermometers in the majority of refrigerators. It is essential to check the temperature of the freezer and fridge often, particularly in the event of an outage in power or you've manually changed the temperature setting. The ideal temperature for both the refrigerator and freezer is 40 degrees Fahrenheit. Capacity for Storage The capacity of your refrigerator is an important factor in deciding on the model that will best suit your needs. There are numerous sizes to pick from, ranging from tiny refrigerators with a capacity of less than 15 cubic feet to large models that can accommodate more than 26 cubic feet. To determine the size you need, consider your family's cooking habits and the number of people living in your home. For two people with a family of two, an average of 11 to 13 cubic feet of refrigerator space is enough, while 18 to 22, cubic feet is recommended. In addition to assessing the overall space of your kitchen take a look at the depth of your refrigerator. Certain models are more deep than others, allowing them to fit into tight spaces and not take up too much space under your counters. Cabinet-depth refrigerators are another option, and have a depth that is roughly the similar to the typical kitchen cabinet front (though handles may protrude slightly farther). These are a good option for homes with a limited counter space. They also appear sleeker. Find out about the refrigerator's energy usage and noise level when you are shopping. There are many manufacturers that offer quieter options for residential use, while certain models consume less energy than comparable models. You can find the energy usage of a refrigerator by looking at the yellow Energy Guide label. Also, test a model's operation by opening and closing the doors. The pantry drawer is usually a full width section of the refrigerator with separate temperature controls. It can be used to store various items. These drawers are ideal for storing party trays and wine, as they allow you to store them at a specific temperature. Based on the model, these drawers may have pre-programmed settings for wines and deli meats as well as soft drinks. Energy Efficiency Refrigerators use a lot of energy. This is why it's important to select one that is energy efficient. Over time refrigerators have become more energy-efficient. The insulation, motors and magnetic door seals on a modern refrigerator use less energy than an older fridge similar to its size. It is possible to reduce the energy consumption of your refrigerator further by purchasing a highly energy efficient model. A refrigerator that is Energy Star rated will consume much less energy than a comparable model 10 years old or more. It is important to consider energy efficiency for those who have limited access to electricity grids. Refrigerators are typically one of the most expensive appliances for off-grid households and their large energy consumption means they require huge solar home systems (SHS) that are not affordable for many families earning $2 per day or less. A refrigerator's annual energy consumption is therefore a crucial factor in determining whether it is economical for consumers to purchase and operate (PATH and WHO 2013; McCarney et al, 2012). To understand how refrigerators function first, we must understand the fundamental refrigeration cycle. The refrigerator cools down by pushing a refrigerant fluid through a sealed system. It starts as a liquid, and then goes through the compressor, which compresses it to form an vapor. This vapor is then pumped into coils that are located on the outside of the refrigerator where it draws the heat from the fridge, settling down before turning back into the liquid. This process is repeated repeatedly and keeps food cold as the vapor circulates through the coils. Refrigerators are still among the most expensive items that consumers who are not connected to the grid can purchase, but improving their energy efficiency can make them more affordable. By reducing the amount of energy they consume the refrigerator can be powered by an enlarge SHS, which will reduce the overall cost of the system for consumers. Based on the size, style and features of the refrigerator, the energy savings will vary. For example, ice-makers and through-the-door water dispensers add cost, but can substantially increase the energy use and, in turn, increase the amount of SHS needed to power it. Maintenance Regular maintenance and inspection can greatly improve the lifespan of your refrigerator. Examine the condenser, the ice maker, and the defrost drain. Also, check the seals on the door. Additionally, cleaning and replacing water filters are also important. These easy maintenance tasks will ensure the longevity of your refrigerator and also save money on your energy costs. Cleaning the interior of your fridge on a regular basis is the most efficient and effective way to maintain it. This includes throwing away old food items and wiping down shelves as well as walls, crispers, and inside the doors of your freezer and refrigerator. This will reduce the risk of foodborne illness and unpleasant odors. A refrigerator thermometer is a good option to monitor the temperature of your fridge regularly. If your refrigerator is not properly maintained could be subject to temperature fluctuations that could result in food spoilage and a higher cost of electricity. The condenser coils inside your refrigerator are also required to be cleaned twice a year. This will get rid of any hair, dirt, grime or other debris that has accumulated. These coils are located on the bottom or back of your appliance and are basically radiator-like components that help remove heat from your refrigerator. When www.frydge.uk are dirty, they won't be able to disperse heat as effectively and your refrigerator will require more energy to run. Examine the seal of your refrigerator that is designed to create an airtight seal between your fridge and the ductwork that runs through your home. It is important to keep the contents of your fridge cool. However with time, the seal may be worn down by greasy fingerprints and sticky syrups. To keep the gasket of your refrigerator in good shape, you should often clean it with a the help of a damp cloth. It is also an ideal idea to clean the drip pan, which is typically situated under the compressor unit. The drip pan is responsible to collect the water that is drained from the refrigerator's defrost process. It should be cleaned frequently to prevent the growth of mold and unpleasant smells.
