How a Car Fridge Works

How a Car Fridge Works

When it comes to planning an outdoor adventure, there are a lot of things you can keep in mind. The destination, your vehicle’s capabilities and accommodations, the weather conditions, and of course, your supplies and food. If you’re someone who doesn’t want to spend the majority of your trip scouring gas stations or convenience stores for healthy snacks, a car fridge is an invaluable tool that can elevate your adventure beyond dehydrated food and canned beverages.

But not all car fridges are created equal, and deciding which one to buy isn’t as simple as grabbing the first one you see at a store or online. There are a number of factors to consider, from cooling type and capacity to power source and insulation quality. The best way to choose the right fridge for your needs is to understand how different models work and how each can be used.

Refrigerators work by removing heat from the inside of the refrigerator box. They do this by using a process called “phase changes.” Liquid refrigerant is extracted from the compressor into the refrigerator box. The liquid then evaporates into a gaseous state, takes away heat from the inside of the box, and cools the food and drinks within. When the temperature in the fridge reaches the desired setting, it switches off.

Some of the more popular types of portable car fridges are compressor-based. These are the most efficient and capable of freezing foods, so they’re a great choice for camping trips or other long excursions. They also tend to be smaller than other models, which can make them a good choice for tight spaces or those who are concerned about space limitations.

Another option is a thermoelectric fridge. These use P-N junctions made from special semiconductor materials to create a temperature difference. This causes the side of the fridge that is touching the food to cool down, while the other side gets warmer. This allows the refrigerator to be both a cooler and a freezer, but it’s less efficient than compressor models and doesn’t reach very low temperatures.

Lastly, there are absorption fridges. These are a bit more complicated than compressor or thermoelectric fridges, but they have the advantage of being able to operate in a wide range of temperatures. These fridges are also small, but they may take longer to achieve their target temperature. In addition, these fridges are a little more expensive than other models. When choosing a car fridge, it’s important to weigh efficiency, size, and power source compatibility against price and durability. The right choice can make a big difference in how much you enjoy your next outdoor excursion!
