How to Choose a Refrigerator

Refrigerators are kitchen appliances used to keep food and beverages cold. They are commonly used in offices, homes, hotels and college dorms.

Some refrigerators have intelligent features, such as cameras and sensors. Some refrigerators have touchscreens that allow you to watch videos, search for recipes, view family calendars and shopping lists. You can also leave notes.

Control of Temperature

The proper temperature in the refrigerator keeps foods safe for storage which slows down the degradation of many food items due to spoilage. This is particularly important for foods such as eggs and milk, which could quickly rot when exposed temperatures outside but remain stable in the refrigerator. Refrigerators can be used to store pharmaceuticals such as vaccines or drugs which lose their effectiveness over time. Refrigerator monitoring systems are in place to help ensure a medical facility or laboratory maintains an appropriate cold chain.

The internal thermal insulator of a refrigerator keeps its contents cooler than surrounding air. It makes use of the heat pump to move warm air out of 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 the internal temperature exceeds the pre-set threshold. This prevents bacteria from growing within the refrigerator.

Each zone of the fridge is designed to serve a particular function. The bottom shelves are great for perishables like fresh vegetables and meats that require the lowest temperature to keep their texture and flavor. The shelves should be kept clear in order to allow cool air to circulate in the refrigerator. Store soft cheeses and cured items in a separate drawer for deli to create the perfect charcuterie platter.

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

Many refrigerators come equipped with thermometers, but for those who don't, a stand-alone appliance thermometer is an inexpensive method of monitoring the fridge and freezer temperature. It is important to check the temperature of the fridge and freezer often, especially when there is a power failure or if you manually altered the temperature setting. The ideal temperature for the freezer and refrigerator is 40 degrees Fahrenheit.

Capacity of Storage

The capacity of the refrigerator is a crucial factor in choosing the right model for your requirements. There are a variety of sizes to choose 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. To figure out the size you need, consider the cooking habits of your family and the number of people living 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 three to four persons.

Take a look at the depth of the fridge, in addition to the space. Certain models are deeper than others, which allows them to fit in tight spaces and not take up too much space under your counters. Cabinet-depth fridges are also an alternative. Their depth is comparable to that of a standard kitchen cabinet front, however the handles may extend a little further. They are a great choice for homes where counter space is at a premium, and they can also look sleeker than traditional fridges & Freezers.

Ask about the energy consumption of the refrigerator and the level of noise when you are shopping. There are many manufacturers that offer quieter refrigerators suitable for homes. Others offer refrigerators with less electricity consumption than similar models. Take a look at the yellow Energy Guide label on appliances to find out the typical energy usage for a specific model. Test the appliance by opening and shutting its doors.

The majority of modern refrigerators have the pantry drawer. It is a full-width area with separate temperature controls that can be used for storing various things. These drawers can be used to store trays for parties as well as wine and other things at a specific temperature. Based on the model, these drawers could include pre-programmed settings to store wines as well as deli meats, soft drinks.

Energy Efficiency

Refrigerators consume a lot of energy. Therefore, it is important to choose an energy-efficient refrigerator. The good news is that refrigerators have become more energy efficient in the past. The insulation, motors and magnetic door seals of a newer refrigerator will use less energy than a previous model similar to its size. You can lower the power consumption of your refrigerator even more by buying one that is energy efficient. A refrigerator that has an Energy Star rating will use less energy than a model at least ten years old.

Efficiency in energy is crucial for those who have no access to the grid for electricity. Refrigerators are typically one of the most expensive appliances for homes that are not connected to the grid and their large energy consumption means they require large solar home systems (SHS) that are not affordable for many families making less than $2 per day. The energy consumption of a refrigerator is therefore a crucial aspect in determining if it is affordable for consumers to purchase and operate (PATH and WHO 2013; McCarney et al, 2012).

To understand how fridges work, we start with the basic refrigeration cycle. A refrigerator cools by pushing a liquid refrigerant through a sealed device: it starts as a liquid, then passes through a compressor that compresses the liquid to form an vapor. This vapor then flows into coils that are located on the outside of the fridge where it draws the heat from the fridge, then cooling down and turning back to a liquid. This process repeats over and over again, keeping food cold as the vapor circulates through the coils.

While refrigerators are among the most expensive appliances available to off-grid consumers, increasing their energy efficiency makes them more affordable. A refrigerator that is powered by a smaller SHS will be powered with less energy. This will lower total cost of the system. The savings in energy are contingent on the size, style and other features of the refrigerator. Water dispensers and ice makers through the door, for example, add cost however they can also increase the energy consumption of the refrigerator, which in turn increases the amount of SHS required to power it.

Maintenance

Regular maintenance and inspection can greatly improve the lifespan of your refrigerator. This can be accomplished by checking the condenser coils the ice maker, the defrost drain and the gasket seal on the door to ensure that it is in good working order. Cleaning and replacing water filter is also important. Performing these simple maintenance tasks can prolong the life of your fridge and save money on energy bills.

The easiest and most effective refrigerator maintenance task is to clean the inside of your refrigerator frequently. This includes throwing away old food items, wiping down shelves and crispers, walls, and the interior of your refrigerator's doors. This will reduce the risk of foodborne illnesses and unpleasant smells. It is also recommended to periodically check the temperature of your refrigerator by using an electronic thermometer in your refrigerator. Unmaintained fridges may experience temperature fluctuations that can lead to food waste and higher electricity costs.

It is also crucial to clean the condenser coils in your refrigerator at least twice per year to get rid of any dirt hair, dust, and other debris that may have been accumulating. These coils, which are actually radiators that help remove heat from the refrigerator are located at the bottom or back of your appliance. If they're dirty, they aren't able to release heat as efficiently and your fridge will require more energy to run.

Another thing you should be checking often is the gasket in your refrigerator, which is designed to create an air-tight seal between your refrigerator and your home's ductwork. It is essential to ensure that your fridge's contents remain cold. However, over time, the seal could be damaged by greasy fingerprints and sticky syrups. Clean the seal of your fridge freezers with a a damp towel to keep it in good shape.

It is also a good idea to clean the drip pan, which is normally located under the refrigerator's compressor unit. The pan is used to collect the water that comes from the defrost cycle and must be wiped down on a regular basis to avoid the accumulation of mold or unpleasant odors.
