How to Choose a Refrigerator

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

Some refrigerators are equipped with smart features like sensors and cameras. Some refrigerators have touchscreens that let you view videos and search for recipes, look up family calendars and shopping lists, or even write notes.

Temperature Control

The right refrigerator temperature will ensure food safety and avoid spoilage. This is especially crucial for foods like eggs and milk, which could quickly rot when exposed temperatures that are not ideal but stay stable in the refrigerator. Refrigerators can be used to store pharmaceuticals such as vaccines or drugs that become less effective as time passes. Refrigerator monitoring systems can ensure that the medical lab, laboratory or another institution has an effective cold chain.

A refrigerator's internal thermal insulator 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 storage compartment where it becomes very cold. The refrigerator has a controlled system that turns on the cooling system when its internal temperature is higher than a predetermined threshold. This stops the growth of bacteria inside the refrigerator.

Each refrigerator zone is designed for a different purpose. The bottom shelves are perfect for perishables like fresh vegetables and meats that require the lowest temperature to keep their texture and flavor. Keeping the shelves clear allows cool air to circulate through the refrigerator. A separate deli drawer can be used to store soft cheeses and cured meats to create the perfect charcuterie board.

Refrigerators also have glass or stainless steel doors to protect the interior and allow for easy cleaning. Some refrigerators come with a door alarm that can be programmed. It will notify you when the fridge or freezer is left open for too long. They can be set to notify multiple people in escalating tiers based on your needs. They can be configured to record and send temperature graphs remotely via email or text.

Many refrigerators come equipped with thermometers however, for those who don't, a stand-alone appliance thermometer can be a cheap way to check the temperature of your freezer and fridge. It is essential to check the temperature of the freezer and refrigerator often, especially after a power outage or if temperature settings are manually adjusted. The ideal temperature for both the freezer and refrigerator is 40 degrees Fahrenheit.

Capacity of Storage

The capacity of your refrigerator is an important factor in deciding on the model that best suits your needs. There are many sizes to pick from, from small refrigerators that can hold a volume of less than 15 cubic feet to large models that can contain more than 26 cubic feet. To determine the size you need, consider the cooking habits of your family and the number of people who live in your home. On average, 11-13 cubic feet of refrigerator space is sufficient for two people, whereas 18 to 22 cubic feet is recommended for a family of three to four.

In addition to looking at the total interior space consider the depth of your fridge. Certain models are deeper than others to allow them to fit in tight spaces and not take up too much space under your counters. Cabinet-depth refrigerators are another option. They have a depth similar to the depth of a typical kitchen cabinet, but the handles may extend a little more. They are a great option for kitchens where counter space is at a premium and also look more sleek than traditional refrigerators.

Ask about the energy consumption of the refrigerator and noise level when shopping. There are many manufacturers that offer quieter options for residential use, and some offer refrigerators that consume less energy than similar models. Look for the yellow Energy Guide label on appliances to learn about the typical energy usage for a specific model. Test the appliance by opening and closing its doors.

The pantry drawer is usually the largest section of the refrigerator with separate temperature controls. It can be used to store various things. These drawers are especially useful for storing party trays and wine, as they permit you to keep them at specific temperatures. Based on the model, these drawers may include pre-programmed settings to store wines as well as deli meats, soft drinks.

Energy Efficiency

Refrigerators use a lot of electricity. Therefore, it is important to choose an energy-efficient refrigerator. The good news is that refrigerators have become more energy efficient over time. Motors, insulation, and magnetic door seals have all improved over time, so the latest refrigerator will consume less energy than a model older in the same size. You can lower the power consumption of your refrigerator more by choosing one that is energy efficient. A refrigerator with an Energy Star rating will use much less energy than a model that is at least ten years old.

It is important to consider energy efficiency for those who have limited access to electricity grids. Refrigerators are usually one of the most expensive appliances for households that are off grid, and their high energy consumption means that they require large solar home systems (SHS) that are not affordable for many families earning $2 per day or Refridgerator less. The annual energy usage of refrigerators is an important aspect to determine if it's affordable for consumers to purchase and operate. (PATH and refridgerator WHO 2013 ). McCarney and. al., 2012).

To understand how refrigerators function, we start with the fundamental refrigeration cycle. A refrigerator cools down by pushing a refrigerant fluid through an enclosed system. It starts out as a fluid, then goes through the compressor, which makes it compress into an vapor. This vapor then flows into coils that are located on the outside of the fridge where it draws heat from the fridge, then cooling down before turning back into the liquid. This process is repeated repeatedly to keep food cool as the vapor flows through the coils.

Refrigerators remain one of the most expensive appliances that consumers who live off grid can buy however, improving their energy efficiency can make them more affordable. By decreasing the amount of energy they consume, a refrigerator can be powered by less energy and lower the overall cost of the system for consumers. Based on the dimensions, style, and features of the refrigerator, the energy savings will vary. For instance, ice-makers and through-the-door water dispensers can add cost, but they can also substantially increase the energy consumption, which in turn increases the amount of SHS required to power it.

Maintenance

Regular maintenance and inspections can greatly improve the lifespan of your refrigerator. Check the condenser unit, the ice maker, and the defrost drain. Also, check the seals on the door. Cleaning and changing water filters is essential. Doing these simple tasks can extend the lifespan of your refrigerator and also save money on energy bills.

The simplest and most efficient refrigerator maintenance task is to wash the inside of your refrigerator on a regular basis. This includes throwing away old food items, cleaning shelves and crispers, walls and the interior of your refrigerator's doors. This will lower the chance of contracting foodborne illness and unpleasant odors. It is also recommended to periodically check the temperature of your refrigerator by using a fridge thermometer. Refrigerators that are not maintained can experience temperature fluctuations that could result in food waste and higher electric costs.

The condenser coils inside your refrigerator are also required to be cleaned every two years. This will get rid of any hair, dirt, grime or other debris that may have accumulated. These coils, which are basically radiators that help remove heat from the refrigerator, are located in the rear or bottom of your appliance. These coils aren't able to release the heat as effectively when they are dirty. Your refrigerator will consume more energy to run.

Check your refrigerator's seal which is designed to provide an airtight seal between your refrigerator and the ductwork inside your home. This is essential to ensure that your fridge's contents stay cold But over time, the seal may wear down by greasy fingerprints, sticky syrups, and dripping beverages. To keep the gasket of your refrigerator in good working order, frequently clean it with the help of a damp cloth.

Lastly, it is recommended to clean the drip pan, which is usually situated under the compressor unit. This pan is used to collect the water that is drained from the defrost process, and it should be cleaned regularly to avoid the buildup of odors and mold.
