How to Choose a Refrigerator
Refrigerators (sometimes called fridges) are kitchen appliances that keep food and drinks cold. They are commonly used in homes, offices, hotels and college dorms.
Some refrigerators are equipped with intelligent features, such as sensors and cameras. Some refrigerators are equipped with touchscreens that let you view videos and search for recipes, browse family calendars and shopping lists. You can also leave notes.
The correct refrigerator temperature ensures that food items are safe for storage, slowing the deterioration of many food items due to spoilage. This is particularly important for foods such as eggs and milk, which can quickly turn rotten when exposed to ambient temperatures but remain stable in the refrigerator. Refrigerators are also extensively used to store pharmaceutical products such as vaccines and drugs that become less effective as time passes. Refrigerator monitoring systems are available to help ensure an medical laboratory or medical facility keeps a safe cold chain.
The thermal insulator inside a refrigerator keeps its contents cooler than surrounding air. It uses an energy source to transport warm air out of the refrigerator into an insulated compartment where it becomes very cold. The refrigerator has a control system that turns on the cooling system if its internal temperature is higher than a predetermined threshold. This prevents the formation of bacteria within the refrigerator.
Each zone of the fridge is designed to serve a particular purpose. The bottom shelves are ideal to store perishables such as fresh vegetables and meats which require the minimum temperatures to preserve their taste and texture. Clear shelves allow cool air to circulate through the refrigerator. Store soft cheeses and cured food items in a separate deli drawer to create the perfect charcuterie platter.
Refrigerators also come with stainless steel or glass doors to protect the interior and facilitate cleaning. Some refrigerators have a door alarm that can be programmed to alert you when the freezer or fridge doors are left open for too long. You can set them to alert multiple people and in increments based on your needs. They can also be programmed to record and send temperature graphs remotely via 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 after a power outage or if temperature settings are manually adjusted. The ideal temperature for the freezer and refrigerator is 40 degrees Fahrenheit.
Capacity of Storage
The capacity of your refrigerator is an important factor when choosing the model that best suits 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 can accommodate more than 26 cubic feet. To figure out the size you require, think about your family’s eating habits and the number of people who live in your home. On average, 11-13 cubic feet of refrigerator space is enough for two people, while 18 to 22 cubic feet is recommended for a family of three to four.
Look at the depth of the fridge, in addition to the total space. Some models are more shallow than others, allowing them to fit in tight spaces without taking up too much room under the counters. Cabinet-depth refrigerators are another option, with the depth being roughly the similar to a standard front of a kitchen cabinet (though handles might protrude a bit more). These can be a good option for areas where counter space is at a premium and also appear more stylish than traditional fridges.
Be sure to inquire about the energy consumption of the refrigerator and noise level when shopping. Many manufacturers offer quieter models for residential use, and others offer refrigerators that use less energy than comparable models. Look for the yellow Energy Guide label on appliances to find out about the typical energy consumption for the specific 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 to store various things. These drawers are ideal for storing party trays and wine, since they allow you to keep them at certain temperatures. Based on the model, these drawers might include pre-programmed settings to store wines as well as deli meats, soft drinks.
Refrigerators consume a lot of electricity. This is why it’s important to select one that is energy efficient. As time has passed refrigerators have become more energy-efficient. Insulation, motors, and magnetic door seals have been improved over time, so a newer fridge will use less power than a previous model of the same size. It is possible to cut down on the energy consumption of your refrigerator further by purchasing a highly energy efficient model. A refrigerator that has an Energy Star rating will use much less energy than a model 10 years old or older.
Energy efficiency is particularly important for those who have no access to the grid for electricity. Refrigerators are often among the most costly appliances for households that are off grid, and their large energy consumption means they require huge solar home systems (SHS) that are unaffordable for families earning less than $2 a day. A refrigerator’s annual energy consumption is therefore an important element in determining whether it is economical for consumers to buy and run (PATH and WHO 2013; McCarney et al, 2012).
We will begin by describing the fundamental refrigeration cycle. The refrigerator cools down by pushing a refrigerant liquid through a sealed system. It starts out as a liquid, and then goes through the compressor that compresses it to form the form of a vapor. This vapor flows into coils outside of the refrigerator, and draws heat from it. It then cools before returning to liquid. This process is repeated many times, ensuring that the food remains cold while the vapor moves through the coils.
While refrigerators remain among the most expensive appliances for off-grid consumers, improving their energy efficiency makes them more affordable. By reducing the amount of energy they consume the refrigerator can be powered by a smaller SHS and reduce the overall cost of the system for consumers. Depending on the size, style and features of the refrigerator, the energy savings will vary. Ice makers and water dispensers that are located through the door, for instance, add cost, but can increase the energy consumption of the refrigerator, which increases the amount of SHS required to run it.
The life span of a refrigerator could be significantly improved by regular maintenance and inspection. This can be accomplished by checking the condenser coils, ice maker, defrost drain, as well as the gasket seal on the door to make sure that it is in good working order. Cleaning and replacing the water filter is also vital. Doing these simple tasks can extend the life of your american fridge and reduce your energy costs.
The simplest and most efficient refrigerator maintenance task is to clean the interior of your refrigerator on a regular basis. This includes throwing out old food items and wiping the shelves, crispers, walls, and even inside the doors of your freezer and refrigerator. This will eliminate unpleasant odors as well as reduce the risk of foodborne illnesses. A refrigerator thermometer is a good option to monitor the temperature of your fridge frequently. Unmaintained fridges can experience temperature fluctuations which can cause food waste and higher electric costs.
The condenser coils in your refrigerator should also be cleaned at least twice a year. This will get rid of any dirt, grime, hair or other debris that has built up. These coils are located on the rear or bottom of your appliance. They are basically radiator-like components that help remove heat from your refrigerator. These coils aren’t able to release the heat as efficiently if they are dirty. Your refrigerator will consume more energy to run.
Another thing to be able to check frequently is the gasket on your refrigerator, which is designed to form an airtight seal between the refrigerator and the ductwork in your home. It is important to ensure that your fridge’s contents remain cold. However in time, the seal can be worn down by greasy fingerprints and sticky syrups. To keep your fridge’s gasket in good shape, you should frequently clean it with the help of a damp cloth.
It is also a good idea to clean the drip tray, which is typically underneath the compressor unit of the refrigerator. The pan is used for collecting the water from the refrigerator’s defrost process. It should be cleaned regularly to avoid the development of mold and unpleasant odors.
