How to Choose a Refrigerator
Refrigerators (sometimes called a fridge) 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 are equipped with intelligent features, such as cameras and sensors. Some refrigerators are equipped with touchscreens that allow you to watch videos or search for recipes, look up family calendars and shopping lists, or even write notes.
Temperature Control
The right temperature for refrigerators keeps foods safe for storage and slows the degradation of many foods due to spoilage. This is especially crucial for foods such as eggs and milk, which could quickly rot when exposed to temperatures that are not ideal but stay stable in the refrigerator. Refrigerators are also extensively used to store pharmaceuticals like drugs and vaccines that lose efficacy over time. Monitoring systems for refrigerators can help ensure that a medical facility, laboratory or other establishment maintains a cold chain.
A refrigerator is equipped with an internal thermal insulator that helps keep its contents cooler than the surrounding temperature. The heat pump transports warm air from outside the refrigerator into 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 the threshold set by the manufacturer. This prevents bacteria from growing inside the refrigerator.
Each zone of the fridge is specifically designed to serve a certain function. The lower shelves are perfect for storing perishable items such as fresh meats and vegetables that require the minimum temperatures to preserve their taste and texture. The shelves must be kept clean to allow cool air to circulate through 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 easier to clean. Certain refrigerators also 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 up to notify multiple people and in increments based on your requirements. They can even be set to record and send temperature graphs remotely via email or text.
The majority of refrigerators come with thermometers however for those that don't, an independent appliance thermometer is an inexpensive method of monitoring the temperature of your freezer and fridge. It's important to check the temperature of your freezer and refrigerator frequently, particularly in the event of a power failure or if temperature settings are altered manually. Ideal temperature for both the refrigerator and freezer is 40 degrees Fahrenheit.
Storage Capacity
The capacity of your refrigerator is an important factor in choosing the right model to meet your needs. There are a variety of sizes to choose from, ranging from tiny refrigerators that have a capacity of less than 15 cubic feet to large models that accommodate more than 26 cubic feet. Consider your family's cooking style and the number of people living in your home to figure out which size is suitable for you. For two people, an average of 11 to 13 cubic foot of refrigerator space is sufficient and 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, which allows them to fit in tight spaces and not take up too much space
under counter fridge ice box your counters. Cabinet-depth refrigerators are another option, and have an overall depth that is the same as a standard front of a kitchen cabinet (though handles may protrude slightly further). These are a good option for homes with a limited counter space. They can also look more sleek.
Find out about the energy consumption of the refrigerator and noise level when you are shopping. Many manufacturers offer quieter refrigerators for residential use. Others offer refrigerators with less electricity consumption than similar models. Check the yellow Energy Guide label on appliances to learn about the typical energy usage for the particular model. Test the appliance by opening and closing its doors.
Most modern refrigerators include a pantry drawer, which is a full-width compartment with separate temperature controls that can be used for storing a variety of things. These drawers are especially useful for storing party trays as well as wine, since they allow you to store them at a specific temperature. These drawers 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 energy. That's why it's crucial to have one that is energy efficient. Over time, refrigerators have become increasingly energy efficient. Insulation, motors, and magnetic door seals have all improved over time, so the latest refrigerator will consume less power than a model older in the same size. You can lower the power consumption of your refrigerator even more by choosing a model that is highly energy efficient. A refrigerator that has an Energy Star rating will use much less energy than a model ten years or older.
Efficiency in energy is crucial for consumers who have limited access to the grid for electricity. Refrigerators are typically among the most costly appliances for homes that are not connected to the grid, and their high energy consumption means that they require large solar home systems (SHS) which aren't affordable for families earning less than $2 a day. A refrigerator's annual energy consumption is therefore an important aspect in determining if it is affordable 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 down by pushing a refrigerant fluid through an enclosed system. It begins as a fluid, then goes through the compressor that makes it compress into the form of a vapor. The vapor then flows through coils outside the fridge and draws heat from it. It then cools down and then returns to liquid. This process is repeated repeatedly, keeping food cold as the vapor moves through the coils.
Refrigerators remain among the most expensive appliances that consumers who are not connected to the grid can purchase, but improving their energy efficiency will make them more affordable. A refrigerator that is powered by a smaller SHS will be operated with less energy. This can lower the overall system costs. Energy savings differ based on the size, style and features of the refrigerator. For instance, ice-makers and through-the-door water dispensers add cost, but can significantly increase the energy consumption which, in turn, increases the SHS required to power it.
Maintenance
The lifespan of a refrigerator can be greatly improved with regular maintenance and inspection. This can be done by checking the condenser coils ice maker, defrost drain and the gasket seal on the door to ensure it is in good condition. Cleaning and replacing the water filter is also essential. These simple maintenance tasks will ensure the longevity of your refrigerator and save money on your energy bills.
Cleaning the inside of your fridge on a regular basis is the easiest and most efficient way to keep it in good condition. This includes throwing away old food, wiping down shelves and crispers, walls, and the interior of your refrigerator's doors. This will prevent unpleasant odors and lower the risk of foodborne illnesses. A
free standing fridge thermometer is recommended for checking the temperature of your fridge frequently.
