How to Choose a Refrigerator

Refrigerators (sometimes called fridges) are kitchen appliances that keep food and drinks cold. They are used at home as well as in hotels, offices, and college dorm rooms.

Some refrigerators are equipped with smart features, such as cameras and sensors. Some refrigerators have touchscreens that let you watch videos, search for recipes, browse family calendars, or shopping lists or leave notes.

Control of Temperature

The right temperature for refrigerators ensures that food items are safe for storage which slows down the degradation of many foods due to spoilage. This is especially true for food items like eggs and milk, which quickly turn rotten at room temperature but remain stable at refrigerator levels. Refrigerators can be used to store pharmaceuticals like drugs or vaccines which lose their effectiveness with time. Refrigerator monitoring systems can help ensure that the medical facility, laboratory or other establishment maintains an effective cold chain.

A refrigerator is equipped with an internal thermal insulator to keep its contents colder than the surrounding air. It uses a heat pump to move warm air outside the refrigerator into an insulated compartment, where it becomes very cold. The refrigerator also has a control system that turns on the cooling system when its internal temperature is above the pre-set threshold. This prevents bacteria from growing in the refrigerator.

Each of the refrigerator zones is designed to serve a distinct function. The lower shelves are ideal for perishables such as fresh meats and vegetables that require the minimum temperature to preserve their texture and taste. The shelves must be kept clean to allow cool air to circulate in the refrigerator. Store soft cheeses and cured food items in a separate deli drawer for the perfect charcuterie tray.

Some refrigerators have stainless steel or glass doors to protect the interior. They also make it easy to clean. Some refrigerators have a door alarm that can be programmed to warn you if the freezer or fridge doors are left open for too long. They can be set to notify multiple people in escalating tiers depending on your needs. They can even be set to record and send temperature graphs remotely via email or text.

Freestanding appliance thermometers can be a cost-effective alternative to the built-in thermometers found in the majority of refrigerators. It is important to check the temperature of the freezer and fridge often, especially if there has been an outage in power or you have manually changed the temperature setting. Ideally, both the fridge and freezer should be set at 40 degrees Fahrenheit or below.

Storage Capacity

Refrigerator capacity is an important aspect to consider when choosing the best model for your needs. There are many sizes to pick from, ranging from small refrigerators that have a capacity of less than 15 cubic feet, to larger models that accommodate more than 26 cubic feet. Consider your family's cooking style and the amount of people living in your home to figure out which size is suitable for you. For two people, an average of 11-13 cubic foot of refrigerator space is enough, while 18 to 22, cubic feet is recommended.

In addition to looking at the space inside take a look at the depth of your refrigerator. Certain models are larger than others to allow them to fit in small spaces and not take up too much space under your counters. Cabinet-depth refrigerators are a good alternative. They have a depth similar to that of a standard kitchen cupboard front, though handles may extend a little more. These are a good option for homes with a limited counter space. They can also look sleeker.

When buying a refrigerator, ask about the level of noise and energy consumption. Many manufacturers offer quieter refrigerators for residential use. Other refrigerators have lower electricity consumption than similar models. Take a look at the yellow Energy Guide label on appliances to find out the typical energy usage for the specific model. Also, test the model's operation by opening and closing the doors.

A majority of modern refrigerators come with the pantry drawer, which is a full-width section with separate temperature controls that can be used to store a variety of things. These drawers are especially useful for storing party trays and wine, as they permit you to store them at specific temperatures. These drawers can be programmed to hold wine as well as deli food items, and soft drinks, based on the model.

Energy Efficiency

Refrigerators consume a lot energy. It is therefore important to choose an energy-efficient refrigerator. Over time refrigerators have become more energy efficient. The insulation, motors, and magnetic door seals on a modern refrigerator use less energy than a refrigerator that is similar in size. It is possible to reduce the power consumption of your refrigerator more by purchasing an energy efficient model. A refrigerator that is Energy Star-rated will consume much less energy than a comparable model that is ten years old or older.

It is crucial to think about the energy efficiency of consumers who have limited access to electricity grids. For off-grid homes, refrigerators are typically among the most expensive appliances. Their high energy consumption also implies that they require huge systems of solar home systems that are out of reach for many families who earn less than $2 per day. A refrigerator's annual energy consumption is therefore a key element in determining whether it is economical for consumers to purchase and maintain (PATH and WHO 2013; McCarney et al, 2012).

To understand how fridges function it is important to understand the basic refrigeration cycle. A refrigerator cools down by pushing refrigerant liquid through a sealed system. It starts as a liquid, and then goes through the compressor, which makes it compress into an vapor. The vapor then flows through coils outside of the refrigerator, and draws heat from it. It then cools down, and turns back to liquid. This process repeats repeatedly, keeping food cold as the vapor moves through the coils.

While refrigerators remain among the most expensive appliances for off grid consumers, enhancing their energy efficiency makes them more affordable. A refrigerator powered by a smaller SHS can be operated with less energy. This will lower total system cost. Energy savings vary depending on the size, design, and features of the refrigerator. Ice-makers and water dispensers through the door, for example, add cost however they can also increase the energy consumption of the refrigerator, which can increase the amount of SHS required to power it.

Maintenance

Regular maintenance and inspection can greatly increase the life expectancy of your refrigerator. Examine the condenser, ice maker and defrost drain. Also, look for seals on the door. Cleaning and replacing water filter is also important. Performing these simple maintenance tasks can help prolong the life of your fridge and reduce your energy costs.

Cleaning the interior of your fridge on a regular basis is the simplest and most efficient way to keep it in good condition. This means throwing away old food and wiping down shelves and crispers, walls and inside the doors of your refrigerator and freezer. This can reduce the risk of foodborne illness and unpleasant odors. A refrigerator thermometer is recommended for checking the temperature of your refrigerator regularly. If your refrigerator is not properly maintained may be subject to temperature fluctuations that could cause food spoilage and an increase in your electric bill.

The condenser coils of your refrigerator should be cleaned at least twice a year. This will get rid of any hair, dirt, grime or other debris that may have accumulated. These coils, which are actually radiators that remove heat from the refrigerator, are located at the bottom or rear of your appliance. When these are dirty, they can't dissipate heat as efficiently and your fridge will require more power to run.

Another thing to be able to check often is the gasket in your refrigerator that is designed to create an airtight seal between the fridge freezer Deals and your home's ductwork. This is crucial to ensure that your fridge's contents remain cold However, over time, the seal may wear down from greased fingerprints, sticky syrups and dripping beverages. To keep the gasket of your refrigerator in good working order, often clean it with a a damp cloth.

It is also a good idea to clean the drip tray, which is located typically beneath the compressor unit of the refrigerator. The drip pan is responsible to collect water from the refrigerator's defrost process. It should be cleaned regularly to prevent the growth of mold and unpleasant odors.
