How to Choose a Refrigerator

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

Some refrigerators have intelligent features, such as cameras and sensors. Others have touchscreens to allow you to watch videos, browse recipes, refrigerators browse family calendars and shopping lists, or leave notes for family members.

Control of Temperature

The proper temperature in the refrigerator ensures that food items are safe for storage, slowing the deterioration of many foods due to spoilage. This is especially important for foods like eggs and milk that quickly turn rotten at ambient temperatures but remain stable at refrigerator levels. Refrigerators are also widely used to store pharmaceutical products like vaccines and medicines that lose efficacy over time. Refrigerator monitoring systems can ensure that a medical lab, laboratory or another institution maintains a cold chain.

A refrigerator is equipped with an internal thermal insulator that helps keep its contents colder than the surrounding temperature. It utilizes the heat pump to move warm air out of the refrigerator into an insulated compartment, where it is extremely cold. The refrigerator is equipped with a control system which turns on the cooling system if its internal temperature exceeds a predetermined threshold. This prevents the formation of bacteria inside the refrigerator.

Each of the refrigerator zones is designed for a different purpose. The lower shelves are perfect for storing perishable items such as fresh meats and vegetables, refrigerators which require the most low temperatures to preserve their flavor and texture. Keeping the shelves clear allows cool air to circulate around the refrigerator. A separate deli drawer can be used to store soft cheeses and cured meats for the perfect charcuterie platter.

Refrigerators also feature doors made of stainless steel or glass to protect the interior and facilitate cleaning. Some refrigerators also include door alarms that can be programmed to alert you if the freezer or fridge doors are left open for too long. They can be set to alert multiple individuals and in escalating levels based on your needs. They can even be set to record temperature and send graphs remotely via email or text.

Many refrigerators come equipped with thermometers however, for those that don't, an independent appliance thermometer can be a cheap way to monitor the temperature of the freezer and refrigerator. It is essential to check the temperature of the freezer and fridge often, especially if there has been an electrical failure or you manually altered the temperature setting. Ideally, both the refrigerator and freezer should be set to 40 degrees Fahrenheit or lower.

Capacity for Storage

The capacity of your refrigerator is a key aspect to consider when selecting the model that will best suit your requirements. There are numerous sizes to pick from, ranging from tiny refrigerators that have a capacity of less than 15 cubic feet to large models that can contain more than 26 cubic feet. To determine the size you need, consider your family's cooking habits and the number of people in your home. For two people with a family of two, an average of 11 to 13 cubic foot of refrigerator space is adequate for a household of two. For a family of three, 18 to 22, cubic feet is recommended.

Look at the depth of the fridge in addition to the total space. Some models are shallower than others, which allows them to fit in tight spaces without taking up too much room under your counters. Cabinet-depth fridges are also an alternative. Their depth is similar to the depth of a typical kitchen cabinet front, however the handles can extend a bit more. These are a great choice for homes with limited counter space. They also appear more sleek.

When shopping for a refrigerator, inquire about its noise level and energy consumption. There are many manufacturers that offer quieter options for use in homes, and others offer refrigerators that use less energy than comparable models. Check the yellow Energy Guide label on appliances to find out about the typical energy consumption of a specific model. Also, test a model's operation by closing and opening the doors.

The majority of modern refrigerators have a pantry drawer, which is a full-width section with separate temperature controls that can be used for storing a variety of objects. These drawers are especially useful to store party trays and wine, since they allow you to store them at specific temperatures. Based on the model, these drawers may include pre-programmed settings to store wines, deli meats and soft drinks.

Energy Efficiency

Refrigerators consume a lot of energy. It is therefore important to choose a energy-efficient refrigerator. The good news is that refrigerators have improved in energy efficiency over time. Insulation, motors, and magnetic door seals have been improved over time, so a modern refrigerator consumes less power than a previous model of the same size. You can reduce the electricity consumption of your refrigerator more by choosing one that is energy efficient. A refrigerator that is Energy Star rated will use a lot less energy than an equivalent model 10 years old or older.

It is important to consider the energy efficiency of consumers who have limited access to electricity grids. Refrigerators are often among the most costly appliances for off-grid households, and their high energy consumption means that they require large solar home systems (SHS) which aren't affordable for many families making less than $2 a day. The annual energy consumption of a refrigerator is therefore a crucial aspect in determining if it is economical for consumers to purchase and maintain (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 system: it starts as a liquid, and then passes through a compressor that reduces the liquid to create the form of a vapor. This vapor then flows into coils located on the exterior of the fridge where it draws heat from the fridge, then cooling down before returning to liquid. This process repeats over and over again, keeping food cold as the vapor circulates through the coils.

Refrigerators are among the most expensive appliances that consumers off-grid can purchase however, improving their energy efficiency can make them more affordable. A refrigerator that is powered by a smaller SHS could be powered by less energy. This will lower total system cost. Energy savings vary depending on the dimensions, design, and features of the refrigerator. Water dispensers and ice makers through the door, for example, add cost, but can increase the energy consumption of the refrigerator, which increases the amount of SHS required to run it.

Maintenance

Regular maintenance and inspection can greatly increase the lifespan of your refrigerator. This can be accomplished by checking the condenser coils the ice maker, defrost drain, and the gasket seal on the door to make sure it is in good condition. Cleaning and replacing water filter is also important. These easy maintenance tasks will aid in prolonging the life of your refrigerator as well as save money on your energy bills.

Cleaning the interior of your fridge regularly is the most efficient and efficient way to keep it in good condition. This means throwing away old food items, wiping down shelves and crispers, walls, and the interior of your refrigerator's doors. This will help prevent unpleasant odors and lower the risk of foodborne illnesses. It is also recommended to periodically check the temperature of your refrigerator using the help of a thermometer for your fridge. Unmaintained fridges are prone to temperature fluctuations that can cause food waste and more expensive electricity costs.

The condenser coils of your refrigerator should also be cleaned every two years. This will eliminate any dirt, grime, hair or other debris that has accumulated. These coils, which are actually radiators that help remove heat from the refrigerator are located in the rear or bottom of the appliance. When these are dirty, they can't dissipate heat effectively and your fridge will require more power to run.

Another thing to check frequently is the gasket on your refrigerator, which is designed to create an air-tight seal between your refrigerator and your home's ductwork. This is essential to ensure that your fridge's contents remain cold However, over time, the seal may wear down from greased fingerprints, sticky syrups and dripping drinks. Clean the seal of your fridge freezer clearance with a the help of a damp towel to keep it in good condition.

It is also recommended to regularly clean the drip pan, which is typically located under the refrigerator's compressor unit. This pan is used to collect water from the defrost cycle, and it should be cleaned regularly to avoid the accumulation of mold or unpleasant odors.
