How to Choose a Refrigerator

Refrigerators (sometimes called fridges) are kitchen appliances that keep food and beverages cold. They are commonly used in homes and in hotels, offices, and college dorm rooms.

Certain refrigerators come with intelligent features, such as cameras and sensors. Some refrigerators are equipped with touchscreens that let you watch videos, search for recipes, look up family calendars, or shopping lists, or even write notes.

Control of Temperature

The proper temperature in the refrigerator ensures that food items are safe for storage which slows down the degradation of many food items due to spoilage. This is especially true for foods like eggs and milk which are susceptible to rotting at room temperature but remain stable at refrigerator levels. Refrigerators can be used to store pharmaceuticals such as vaccines or drugs that become less effective as time passes. Refrigerator monitoring systems are available to ensure that a medical facility or laboratory has an appropriate cold chain.

The internal thermal insulator of a refrigerator keeps its contents cooler than the surrounding air. It uses an energy source to transport warm air outside the refrigerator into an insulated storage compartment where it gets extremely cold. The refrigerator has a control system which turns on the cooling system when its internal temperature is higher than a preset threshold. This stops the growth of bacteria within the refrigerator.

Each of the refrigerator zones is designed to serve a distinct purpose. The lower shelves are ideal for storing perishables like fresh meats and vegetables, which require the lowest temperatures to preserve their flavor and texture. The shelves should be kept clean to allow cool air to circulate in the refrigerator. A separate drawer for deli can be used to store soft cheeses and cured meats to create the perfect charcuterie platter.

Certain refrigerators have glass or stainless steel door to safeguard the interior. They also make it easy to clean. Certain refrigerators also have doors that are alarms that can be programmed to warn you when the doors to the freezer or fridge are closed for too long. You can set them up to alert multiple people, and in escalating levels depending on your needs. They can also be programmed to record and send temperature graphs remotely via text message or email.

Most refrigerators have built-in thermometers however, for those that don't, an independent appliance thermometer is an inexpensive way to check the temperature of your freezer and fridge. It is crucial to monitor the temperature of the freezer and fridge often, particularly when there is an electrical failure or you've manually changed the temperature setting. Ideally, both the fridge and freezer should be set at 40 degrees Fahrenheit or below.

Capacity for Storage

The capacity of your refrigerator is a crucial aspect to consider when selecting the model that will best suit your requirements. There are many sizes to pick from, from small refrigerators with a capacity of less than 15 cubic feet to large models that accommodate more than 26 cubic feet. Take into consideration your family's cooking preferences and the amount of people living in your house to determine the best size for you. On average, 11-13 cubic feet of refrigerator space is enough for two people, while 18 to 22 cubic feet are recommended for three to four persons.

In addition to assessing the overall space of your kitchen take a look at the depth of your fridge. Some models are more shallow than others, which allows them to fit in tight spaces without taking up too much room under your counters. Cabinet-depth refrigerators are a good option. They have a depth similar to that of a standard kitchen cabinet front, however the handles may protrude a little further. They are a great choice for kitchens where counter space is a problem, and they can also look sleeker than traditional fridges.

When shopping for a refrigerator, inquire about the level of noise and energy consumption. There are many manufacturers that offer quieter options for residential use, while others offer refrigerators that use less energy than similar models. Take a look at the yellow Energy Guide label on appliances to find out about the typical energy usage for the specific model. Test the model by opening and closing its doors.

A majority of modern refrigerators come with the pantry drawer. It is a full-width area with separate temperature controls that can be used for storing many different items. These drawers are especially useful to store party trays and wine, as they permit you to store them at a specific temperature. Based on the model, these drawers may come with pre-programmed settings for wine as well as deli meats, soft drinks.

Energy Efficiency

Refrigerators consume a lot of electricity. That's why it is important to have one that is energy efficient. Over the years refrigerators have become more energy efficient. Insulation, motors, and magnetic door seals have all improved over time, meaning that the latest refrigerator will consume less power than a model older in the same size. It is possible to cut down on the refrigerator's electricity consumption even further by buying an energy efficient model. A refrigerator that is Energy Star certified will consume much less energy than an equivalent model ten years old or older.

It is essential to consider energy efficiency for those who have limited access to electricity grids. Refrigerators for homes that are off grid are usually among the most expensive appliances. Their large energy consumption also means that they require large fridge freezers systems of solar home systems which aren't affordable for families earning less than $2 per day. The annual energy usage of refrigerators is an important element in determining whether it's economically feasible for consumers to purchase and operate. (PATH and WHO 2013, McCarney et. and., 2012).

We will start by explaining the basic refrigeration cycle. A refrigerator cools by pushing a liquid refrigerant through a sealed device: it starts as a liquid and is pushed through a compressor that compresses the liquid to form the form of a vapour. The vapor is then pumped into coils outside of the fridge and draws heat from it. It then cools down, and turns back to liquid. This process is repeated several times, keeping food cool while the vapor flows through the coils.

Although refrigerators are among the most expensive appliances for off-grid consumers, increasing their energy efficiency makes them more affordable. By reducing the amount of energy they use it is possible for a refrigerator to be powered by less energy and lower the overall system cost for consumers. Energy savings vary depending on the dimensions, design and other features of the refrigerator. For instance, ice-makers and through-the-door water dispensers add cost, but they can also significantly increase the refrigerator's energy use which, in turn, increases the SHS required to power it.

Maintenance

The life expectancy of a refrigerator can be greatly increased by regular maintenance and inspection. Check the condenser, defrost drain and ice maker. Also, look for seals on the door. Cleaning and replacing water filter is also essential. These simple tasks can help you prolong the life of your refrigerator and save money on your energy costs.

Cleaning the interior of your fridge on a regular basis is the easiest and most effective way to maintain it. This means throwing away old food and refridgerator wiping down shelves as well as walls, crispers, and even inside the doors of your freezer and refrigerator. This can reduce the chance of contracting foodborne illness and unpleasant smells. A fridge thermometer is recommended to check the temperature of your refrigerator regularly. If your refrigerator is not properly maintained can experience temperature fluctuations, which could result in food spoilage and an increase in your cost of electricity.

It is also important to clean the condenser coils in your refrigerator at least twice per year to remove any dirt, hair, dust and other debris that may have built up. These coils, which are basically radiators that remove heat from the refrigerator, are located at the bottom or back of the appliance. They aren't able to disperse the heat as efficiently if they're dirty. Your refrigerator will require more energy to run.

Check your refrigerator's seal which is designed to provide an airtight seal between your refrigerator and the ductwork in your home. This is vital to ensure that the contents of your fridge remain cold But over time, the seal may wear down from greasy fingerprints, sticky syrups and dripping beverages. Clean your fridge's seal with a damp towel to keep it in good shape.

It is also a good idea, to clean the drip tray, which is located generally underneath the compressor unit of the refrigerator. This 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 smells.
