What are refrigerators?
Refrigerators are devices that transfer heat from lower temperature regions to higher temperature regions.

Refrigeration is a process of moving heat from one location to another in controlled conditions. The work of heat transport is traditionally driven by mechanical work, but can also be driven by heat, magnetism, electricity, laser, or other means. Refrigeration has many applications, including, but not limited to: household refrigerators, industrial freezers, cryogenics, and air conditioning.

The Best Refrigerators to Buy in 2019

1- GE Profile Series French-Door Refrigerator
The GE Profile Series French-Door Refrigerator with a Keurig K-Cup Brewing System got top marks for temperature maintenance and uniformity. It also wowed our Kitchen Appliance Lab experts with its smart design features: You get a top-of-the-line fridge, plus a built-in Keurig coffeemaker in the door. It's Wi-Fi enabled, so after you download the app you can adjust settings, preheat water for coffee, and get alerts if the door is open.

2- Samsung Family Hub Refrigerator
Think of Samsung's Family Hub Refrigerator as your family's kitchen command center. With Bixby, Samsung's smart voice assistant, you can ask your fridge to add groceries to a shopping list, order food on Grubhub, or play Pandora (on the built-in speakers). In our tests, we were impressed with its ability to maintain super steady temperatures in the fridge and freezer, which is a must to keep foods fresh.

3- Maytag Wide French Door Refrigerator
For a solid fridge without a hefty price tag, this Maytag model is the one to beat. It has slide-out shelves and a built-in water and ice dispenser with filter. In our tests, fridge and freezer temps held steady and door shelves were cool enough to safely store dairy.

4- LG InstaView Door-in-Door Refrigerator
You can depend on the LG InstaView Refrigerator to do an excellent job of keeping your food fresh, but what really distinguishes it is the unique door-in-door feature: The easy-access compartment lets you quickly grab a snack or beverage without having to open the full door.

5- Kenmore Elite French Door Refrigerator
In addition to steady temps, Kenmore Elite's French door refrigerator is the king of compartments. It delivers tons of storage space, shelves you can adjust for tall items, and two trays plus a drawer in the freezer. Useful climate-controlled bins help extend the life of produce, meat, poultry, and fish.
