How to Choose a Refrigerator

Refrigerators (sometimes called a fridge) are kitchen appliances that keep food and drinks fridge undercounter cold. They are used in offices, refridgerator homes in hotels, restaurants and college dorms.

Some refrigerators are equipped with smart features, such as sensors and cameras. Certain refrigerators come with touchscreens that let you view videos and search for recipes, look up family calendars and shopping lists. You can also leave notes.

Control of Temperature

The right refrigerator temperature will ensure food safety and avoid spoilage. This is particularly important for foods like eggs and milk, which can quickly rot when exposed to temperatures outside but remain stable in the refrigerator. Refrigerators can be used to store pharmaceuticals such as medications or vaccines that lose their efficacy with time. Refrigerator monitoring systems can help ensure that the medical facility, laboratory or any other institution maintains a 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 outside the refrigerator into an insulated compartment, from which it cools to a very low temperature. The refrigerator also has a control system that switches on the cooling system if its internal temperature is above the pre-set threshold. This stops the growth of bacteria in the refrigerator.

Each refrigerator zone is designed to serve a distinct purpose. The bottom shelves are perfect for perishables such as fresh meats and refridgerator vegetables that require the minimum temperature to keep their texture and refridgerator taste. The shelves should be kept clear to allow cool air to circulate through the refrigerator. A separate drawer for deli can be used to store soft cheeses and cured meats to create the perfect charcuterie board.

Some refrigerators feature doors made of stainless steel or glass to protect the interior. They also make it easier to clean. Certain refrigerators also have doors that are alarms that can be programmed to notify you when the freezer or fridge doors are closed for too long. You can set them up to alert multiple people, and in escalating levels based on your requirements. They can also be programmed to record and send temperature graphs remotely via text or email.

Most refrigerators have built-in thermometers however, for those that don't, an independent appliance thermometer is a cost-effective way to monitor the temperature of the freezer and refrigerator. It's important to check the temperature of the freezer and refrigerator often, especially in the event of a power failure or if the temperature settings are changed manually. Ideally, both the refrigerator and freezer should be set to 40 degrees Fahrenheit or below.

Storage Capacity

Refrigerator capacity is an important factor in choosing the right model for your requirements. There are many sizes to choose from, ranging from tiny refrigerators with a capacity of less than 15 cubic feet to large models that can contain more than 26 cubic feet. To determine the size you require, think about your family's cooking habits and the number of people living in your home. For two people the average of 11 to 13 cubic feet of refrigerator space is enough for a household of two. For a family of three, 18 to 22 cubic feet is recommended.

Check the depth of the fridge zanussi, as well as the overall space. Some models are more shallow than others, which allows them to fit into small spaces without taking up too much space under the counters. Cabinet-depth refrigerators are another option, with an overall depth that is the similar to the standard front of a kitchen cabinet (though handles might protrude a bit more). These are a great choice for homes with limited counter space. They also appear more modern.

Be sure to inquire about the refrigerator's energy consumption and noise level when you are shopping. Many manufacturers provide quieter refrigerators for homes. Other refrigerators have less energy consumption than comparable models. You can find the energy consumption average of a particular model by examining the yellow Energy Guide label. Also, test the model's operation by closing and opening the doors.

The majority of modern refrigerators have the pantry drawer, which is a full-width compartment with separate temperature controls that can be used to store various items. These drawers are especially useful for storing party trays as well as wine, as they permit you to store them at certain temperatures. They can be programmed to store wine or deli food items as well as soft drinks, based on the model.

Energy Efficiency

Refrigerators use a lot of electricity. Therefore, it is important to select a refrigerator that is energy efficient. The good news is that refrigerators are becoming more energy efficient in the past. The insulation, motors and magnetic door seals of a modern refrigerator will use less energy than a refrigerator that is similar to its size. It is possible to cut down on the power consumption of your refrigerator further by buying an energy efficient model. A refrigerator with an Energy Star rating will use much less energy than a model 10 years old or older.

Energy efficiency is especially important for those who have no access to electricity grids. Refrigerators are often one of the most expensive appliances for households that are off grid and their high energy consumption means that they require huge solar home systems (SHS) that are not affordable for families earning less than $2 per day. The annual energy consumption of a refrigerator is therefore an important aspect in determining if it is economical for consumers to purchase and operate (PATH and WHO 2013; McCarney et al, 2012).

To understand how fridges function first, we must understand the fundamental refrigeration cycle. A refrigerator cools by pushing liquid refrigerant through a sealed unit beginning as a liquid, then passes through a compressor that reduces the liquid to create a vapor. This vapor flows into coils outside of the fridge and draws heat from it. It then cools down, and turns back to liquid. This process repeats over and over again and keeps 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. By decreasing the amount of energy they use, a refrigerator can be powered by a smaller SHS and reduce the overall system cost for consumers. Based on the size, style, and features of the refrigerator, the savings on energy will vary. For instance, ice-makers and through-the-door water dispensers can add cost, but they can also significantly increase the energy consumption which, in turn, increases the amount of SHS required to power it.

Maintenance

The life span of a refrigerator can be greatly improved with regular maintenance and inspection. Examine the condenser, defrost drain and ice maker. Also, check the seals on the door. Cleaning and replacing water filters is equally important. These simple maintenance tasks can extend the life of your fridge as well as reduce your energy costs.

Cleaning the inside of your refrigerator regularly is the easiest and most efficient method to keep it clean. This includes throwing away old food and wiping down shelves and crispers, walls and inside the doors of your freezer and refrigerator. This will eliminate unpleasant odors and lower the risk of foodborne illnesses. A refrigerator thermometer is recommended to check the temperature of your fridge regularly. Refrigerators that aren't maintained are prone to temperature fluctuations that can lead to food waste and higher electricity costs.

The condenser coils inside 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 accumulated. These coils are located on the rear or bottom of your appliance and are essentially radiator-like parts that help remove heat from your refrigerator. If they are dirty, they won't be able to disperse heat effectively and your fridge will require more power to run.

Another thing you should be checking regularly is your refrigerator's gasket, which is designed to create an air-tight seal between the refrigerator and the ductwork in your home. This is crucial to ensure your fridge's contents stay cold However, over time, the seal could wear down from greased fingerprints, sticky syrups, and dripping drinks. 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 regularly clean the drip pan, which is typically located under the refrigerator's compressor unit. The pan is used to collect water from the refrigerator's defrost process. It is recommended to clean it regularly to avoid the development of mold and unpleasant smells.
