How to Choose a Refrigerator
Refrigerators are kitchen appliances that are used to keep food and drinks cold. They are used in offices, homes in hotels, restaurants and college dorms.
Some refrigerators are equipped with smart features, such as sensors and cameras. Some have touchscreens that allow you to watch videos, search for recipes, view family calendars and shopping lists or leave notes for family members.
Temperature Control
The proper temperature in the refrigerator ensures food is safe to store and slows the degradation of many foods due to spoilage. This is especially true for foods like eggs and milk which are susceptible to rotting at ambient temperatures however, they remain stable in refrigerator temperatures. Refrigerators can also be used to store pharmaceuticals like vaccines or drugs that lose their efficacy over time. Refrigerator monitoring systems can ensure that an medical facility, laboratory or any other institution has an effective cold chain.
A refrigerator's internal thermal insulator keeps its contents cooler than the surrounding air. The heat pump is used to move warm air from outside the refrigerator to an insulated compartment, from which it cools to a very low temperature. The refrigerator has a controlled system that turns on the cooling system if its internal temperature exceeds a preset threshold. This prevents bacteria from forming inside the refrigerator.
Each refrigerator zone is designed for a different purpose. The lower shelves are ideal for perishables such as fresh vegetables and meats that require the lowest temperature to keep their texture and flavor. The shelves should be kept clear to allow cool air to circulate in the refrigerator. Keep soft cheeses and cured items in a separate drawer for deli for the perfect charcuterie tray.
Refrigerators also come with stainless steel or glass doors to protect the interior and allow for easy cleaning. Certain refrigerators have a door alarm that can be programmed. It will alert you if the fridge or freezer is left open for bottom Freezer fridge too long. You can set them to alert multiple people, and in escalating levels based on your needs. They can be configured to record and send temperature graphs remotely via email or text.
The majority of refrigerators come with thermometers, but for those that don't, a freestanding appliance thermometer can be a cheap way to monitor the temperature of the freezer and refrigerator. It is crucial to monitor the temperature of the fridge and freezer often, especially when there is an electrical failure or you manually altered the temperature setting. The ideal temperature for the freezer and refrigerator is 40 degrees Fahrenheit.
Capacity for Storage
The capacity of your refrigerator is an important factor in choosing the right model to meet your needs. There are numerous sizes to choose 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 figure out the size you require, take into consideration the cooking habits of your family and the number of people who live in your home. On average, 11 to 13 cubic feet of refrigerator space is enough for two people, whereas 18 to 22 cubic feet are recommended for a family of three to four.
Take a look at the depth of the pharmacy fridge, as well as the total space. Certain models are deeper than others, allowing them to fit into tight spaces without taking up too much room 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 more). These are a great choice for homes with limited counter space. They can also appear more modern.
Ask about the refrigerator's energy usage and noise level when you are shopping. There are many manufacturers that offer quieter refrigerators suitable for homes. Some offer refrigerators with lower electricity consumption than similar models. Look for the yellow Energy Guide label on appliances to find out the typical energy usage for the specific model. Also, test a model's operation by opening and closing the doors.
The pantry drawer is typically an entire width of the refrigerator that has separate temperature controls. It can be used to store various things. These drawers are ideal for storing party trays as well as wine, as they permit you to store them at certain temperatures. They can be programmed to store wines or deli food items as well as soft drinks, depending on the model.
Energy Efficiency
Refrigerators consume a lot electricity. It is therefore important to choose an energy-efficient refrigerator. Over the years, refrigerators have become increasingly energy-efficient. The insulation, motors and magnetic door seals on a modern refrigerator consume less energy than a previous model 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 with an Energy Star rating will use much less energy than a model that is ten years or older.
Energy efficiency is particularly important for consumers with limited access to the electricity grid. Refrigerators are usually among the most costly appliances for homes that are not connected to the grid Their large energy consumption means they require massive solar home systems (SHS) that are not affordable for families earning less than $2 a day. The annual energy consumption of refrigerators is a crucial factor to determine whether it's affordable for consumers to purchase and operate. (PATH and WHO 2013 ). McCarney et. al. 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: it starts as a liquid and is pushed through a compressor that compresses the liquid into a liquid. The vapor then flows through coils on the outside of the fridge where it draws the heat from the fridge, then cooling down before turning back into a liquid. This process repeats over and over again, keeping food cold as the vapor circulates through the coils.
While refrigerators remain among the most expensive appliances available to off-grid consumers, enhancing their energy efficiency makes them more affordable. A refrigerator that is powered by a smaller SHS can be powered with less energy. This will lower total system cost. Energy savings vary depending on the size, style, and features of a refrigerator. For example, ice-makers and through-the-door water dispensers can add cost but may substantially increase the energy use and, in turn, increase the amount of SHS needed to power it.
Maintenance
Regular maintenance and inspection can significantly increase the life expectancy of your refrigerator. This can be accomplished by inspecting the condenser coils, the ice maker, the defrost drain, and the gasket seal on the door to ensure it is in good condition. Additionally, cleaning and replacing water filters are essential. Performing these simple maintenance tasks can prolong the lifespan of your fridge and reduce your energy costs.
Cleaning the inside of your fridge regularly is the simplest and most efficient method to keep it clean. This includes throwing away old food items and wiping the shelves as well as walls, crispers, and the inside of the doors of your freezer and refrigerator. This will eliminate unpleasant odors and lower the chance of contracting food-borne illnesses. A refrigerator thermometer is recommended to check the temperature of your fridge freezer regularly. If your refrigerator is not properly maintained can have temperature fluctuations, which can lead to food spoilage and a higher cost of electricity.
It is also crucial to clean the condenser coils in your refrigerator every two years to remove any dirt, dust, hair, grime and other particles that might have built up. These coils, which are actually radiators that help remove heat from your refrigerator, are located at the bottom freezer fridge or rear of the appliance. If they are dirty, they won't be able to disperse heat effectively, and your refrigerator will require more energy to run.
Another thing to be able to check frequently is the gasket on your refrigerator, which is designed to create an airtight seal between the fridge and your home's ductwork. This is crucial to ensure that your fridge's contents remain cool However, over time, the seal can become worn down by greasy fingerprints, sticky syrups and dripping beverages. Wipe your fridge's seal with the help of a damp towel to keep it in good condition.
It is also a good idea to clean the drip tray, which is usually underneath the compressor unit of the refrigerator. The pan is used to collect the water from the defrost cycle and must be wiped down regularly to avoid the accumulation of odors and mold.
