How to Choose a Refrigerator
Refrigerators (sometimes called fridges) are kitchen appliances that keep food and drinks cold. They're used at home and in hotels, offices and college dorm rooms.
Certain refrigerators come with smart features, including cameras and sensors. Others have touchscreens to let you watch videos, browse recipes, look up family calendars and shopping lists, or leave notes for family members.
Temperature Control
The correct refrigerator temperature keeps foods safe for storage which slows down the degradation of many food items due to spoilage. This is especially important for food items like eggs and milk, which quickly turn rotten at ambient temperatures however, they remain stable at refrigerator levels. Refrigerators can also be used to store pharmaceuticals like drugs or vaccines that lose their efficacy as time passes. Monitoring systems for refrigerators can help ensure that a medical lab, laboratory or another establishment maintains an effective cold chain.
The thermal insulator inside a refrigerator keeps its contents cooler than the surrounding air. The heat pump is used to move warm air from the outside of the refrigerator into an insulated compartment, where it cools to a very low temperature. The refrigerator has a controlled system which turns on the cooling system if its internal temperature exceeds a predetermined threshold. This stops the growth of bacteria within the refrigerator.
Each refrigerator zone is designed to serve a specific function. The lower shelves are ideal for storing perishable items such as fresh meats and vegetables that require the most low temperatures to preserve their flavor and texture. Clearing the shelves allows cool air to circulate throughout the refrigerator. A separate drawer for deli can be used to store soft cheeses and cured meats to create the perfect charcuterie board.
Refrigerators also have stainless steel or glass doors to protect the interior and allow for easy cleaning. Certain refrigerators also have doors that are alarms that can be programmed to warn you when the freezer or fridge doors are closed for too long. You can program them to alert multiple people and in escalating levels based on your requirements. You can set them up to send temperature graphs by text or email.
Freestanding appliance thermometers can be a cost-effective alternative to the built-in thermometers in the majority of refrigerators. It is important to monitor the temperature of the freezer and refrigerator often, especially during power outages or when temperature settings are changed manually. The ideal is that both the fridge and freezer should be set at 40 degrees Fahrenheit or lower.
Storage Capacity
The capacity of your refrigerator is an important factor in choosing the right model for your requirements. There are many sizes to pick from, from small refrigerators that can hold a volume of less than 15 cubic feet, to large models that can hold over 26 cubic feet. To determine the size you require, take into consideration your family's eating habits and the number of people in your home. On average, 11-13 cubic feet of refrigerator space is sufficient for two people, while 18 to 22 cubic feet are recommended for three to four people.
Look at the depth of the fridge in addition to the overall space. Certain models are more deep than others, which allows them to fit in tight spaces and not take up too much space under your counters. Cabinet-depth refrigerators are a good alternative. They have a depth similar to the depth of a typical kitchen cabinet front, however the handles may protrude a little more. They are a great option for homes where counter space is limited, and they can also look sleeker than traditional fridges.
Ask about the energy consumption of the refrigerator and noise level when shopping. There are many manufacturers that provide quieter refrigerators for residential use. Other refrigerators have lower electricity consumption than similar models. Look for the yellow Energy Guide label on appliances to find out the typical energy consumption of the specific model. Test the model by opening and shutting its doors.
The pantry drawer is typically an entire width of the refrigerator that has separate temperature controls. It can be used to store a variety of items. These drawers can be used to store trays for parties, wine and other items at a particular temperature. Depending on the model, these drawers may have pre-programmed settings for wines, deli meats and soft drinks.
Energy Efficiency
Refrigerators use a lot of electricity. Therefore, it is important to choose a energy-efficient refrigerator. Over time, refrigerators have become increasingly energy-efficient. The insulation, motors and magnetic door seals of a modern refrigerator use less energy than a previous model of the same size. It is possible to cut down on the power consumption of your refrigerator more by purchasing an energy efficient model. fridges uk that is Energy Star certified will use a lot less energy than an equivalent model ten years old or more.
It is important to consider the energy efficiency of consumers who have limited access to electricity grids. Refrigerators are often one of the most expensive appliances for off-grid households and their high energy consumption means that they require large solar home systems (SHS) which aren't affordable for many families making $2 per day or less. The energy consumption of a refrigerator is therefore a crucial element in determining whether it is economical for consumers to buy and run (PATH and WHO 2013; McCarney et al, 2012).
We will start by explaining the basic refrigeration cycle. A refrigerator cools by pushing liquid refrigerant through a sealed system that begins as a liquid, and then goes through a compressor which reduces the liquid to create the form of a vapor. The vapor then flows through coils on the outside of the fridge where it draws heat from the fridge, settling down and turning back to a liquid. This process repeats many times, keeping the food cold while the vapor flows through the coils.
Refrigerators remain among the most expensive appliances that consumers off-grid can purchase however, improving their energy efficiency can make them more affordable. A refrigerator powered by a smaller SHS can be powered with less energy. This will reduce the total cost of the system. Energy savings differ based on the size, style 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, which in turn increases the amount of SHS required to power it.
Maintenance
The lifespan of a refrigerator can be significantly improved by regular maintenance and inspection. This can be done by inspecting the condenser coils, the ice maker, defrost drain, and the gasket seal on the door to make sure it is in good condition. Cleaning and replacing water filter is also vital. These simple tasks can help you prolong the life of your refrigerator as well as save money on your energy costs.
Cleaning the interior of your refrigerator regularly is the most efficient and efficient method to keep it clean. This includes throwing away old food items, cleaning shelves and crispers, walls and inside of your refrigerator's doors. This will help prevent unpleasant odors and lower the risk of foodborne illnesses. It is recommended to check regularly the temperature of your refrigerator by using a fridge thermometer. Unmaintained fridges may experience temperature fluctuations that can lead to food waste and higher electric bills.
It is also essential to clean the condenser coils of your refrigerator every two years to remove any dirt, dust, hair, grime, and other debris that may have been accumulating. These coils, which are actually radiators that help remove heat from your refrigerator, are located in the rear or bottom of your appliance. They aren't able to disperse the heat as efficiently if they are dirty. Your refrigerator will consume more energy to run.
Another thing you should be checking often is the gasket in your refrigerator that is designed to create an airtight seal between your refrigerator and your home's ductwork. It is essential to keep the contents of your fridge cold. However, over time, the seal may be worn down by greasy fingerprints and sticky syrups. To keep the gasket of your refrigerator in good condition, frequently clean it with an aqueous cloth.
In the end, it's recommended to regularly clean the drip pan, which is usually situated under the compressor unit. This pan is used to collect the water that is drained from the defrost process and must be wiped down frequently to prevent the growth of odors and mold.
