How to Keep Food Fresh In a Caravan Fridge During Hot Weather

The only experience more refreshing than sipping a cold drink on a hot summer afternoon is probably doing it while caravanning with your dear ones. Whether it’s sparkling watermelon juice, classic margaritas, or the good old Coke, cold treats can provide a cooling relief from summer’s excruciating heat.

But to enjoy fresh foods during summer, our refrigerators typically have to work overtime. 

For caravanners, running your fridge for longer can accelerate its battery’s degradation or lead to frequent appliance breakdowns. It could also have you rack up astronomical energy bills while traveling (not the ideal way to enjoy your trip). 

Fortunately, you can keep your food fresh in a caravan fridge without necessarily straining the appliance. This post explores ten ways.

1. Start With the Right Caravan Fridge

A refrigerator is arguably the most resourceful appliance for summer caravanners. But with several brands to pick from, it’s easy to get lost in the maze of recommendations. 

While shopping for a proper caravan fridge, start with surface-level considerations like size. Choose an appliance that can comfortably fit in the designated space. 

It’s prudent to consider the refrigerator’s weight as well. Shun bulky models, as these can reduce your touring caravan’s payload capacity and (consequently) its fuel economy. 

After going over the basics, delve into technical aspects like power consumption needs, energy efficiency, and noise emission. 

2. Understand Your Fridge’s Power Requirements

Most caravan refrigerators in Australia fall into two principal categories – Compressor Fridges and Three-way Fridges.

Compressor Refrigerators

Compressor fridges function pretty much like your home’s refrigerator, except that they require 12-volt power sources instead of the conventional 240V mains. These fridges are reasonably efficient and durable. 

However, compressor fridges draw less power compared to their three-way counterparts. Due to that limitation, the refrigerators require powerful batteries and consistent solar energy to keep your food fresh, especially while caravanning off-grid.

Three-Way Fridges

Three-way refrigerators may be plugged into 240-volt mains or 12-volt power sources. These fridges also utilize gas, making them remarkably versatile. Besides, they’re highly energy efficient. 

However, 3-way refrigerators are highly sensitive to ambient temperature fluctuations. You’ll require a robust indoor thermoregulation mechanism to keep these appliances in peak condition.

3. Clean the Refrigerator Ahead Of Each Trip

It’s conventional wisdom to clean your caravan fridge thoroughly before embarking on each trip. A good clean-up helps eliminate odor- and disease-causing microorganisms. 

Fortunately, caravan fridges are incredibly easy to clean. A simple wipe-down using a soft fabric dampened in warm water is all you need to keep the appliance clean. 

Start from the inside and work your way out. 

For stubborn stains, use mild cleaning solutions like sodium bicarbonate. Avoid harsh chemicals like bleach, as these could damage your refrigerator’s surface.

4. Fill Your Refrigerator Sparingly

It’s intuitive to cram your caravan fridge with food, particularly if you’re going on an extended trip. However, overpacking your refrigerator impedes free air flow. 

Note that these appliances require unhindered air circulation to cool the items efficiently. So, allow reasonable breathing space between items. 

It’s better to pack less food than cram your refrigerator, if that only reduces its efficiency. 

One ingenious packing technique is blending differently sized and shaped items. Besides, pack even less food near the vents.

5. Connect Your Refrigerator to the Right Power Source

As mentioned, caravan fridges operate on 12-volt power sources or 240-volt mains. Some also run on gas. 

Having understood your refrigerator’s power consumption needs, ensure you plug the appliance into the right power source. 

Not only will this ensure efficient charging. It also minimizes damage caused by outlet incompatibility issues.

6. Pre-cool Your Refrigerator

Another practical way to keep your food fresh and cool while caravanning is by pre-cooling your refrigerator. 

Plug the fridge into the mains power outlet before embarking on a trip. This will lower the initial energy draw from the appliance’s battery, extending the period before the first battery recharge and keeping your food fresher for longer. 

Note that your caravan fridge type will determine the duration before the next recharge. 

While three-way refrigerators can take up to eight hours to cool down, compressor fridges lose heat much faster.

7. Pre-Freeze The Items

You could also pre-freeze your food in your home’s refrigerator before packing it in your caravan’s fridge. 

Items like bread, milk, and drinks can remain fresh for considerably longer if pre-chilled, enabling you to brave summer’s scorching heat. The same is true for canned foods. 

However, shun products that come in heavy metallic tins, as these are notorious for retaining heat. 

8. Keep It Ventilated

Practicing minimal packing alone may not efficiently improve your caravan refrigerator’s air circulation. To maximize the appliance’s efficiency, ensure the cooling fin and vents are functioning optimally. 

Clean the external vents frequently to dislodge dirt and debris. It’s also best to run your refrigerator ahead of each trip and listen in for any unusual sounds, which could suggest a malfunctioning fin. 

Moreover, place your caravan fridge in a well-ventilated space. Avoid the windows or areas directly exposed to sunlight. 

When day-camping, park your touring caravan such that the side with the fridge faces south. 

9. Implement Robust Temperature Control Measures

Regulating your caravan’s ambient temperature can be significant in keeping your chilled food fresher for longer. 

First, set your caravan fridge’s temperature to around 1 – 4 degrees Celsius. This temperature range denatures microorganisms, preventing them from contaminating your food. 

Besides, open the refrigerator as infrequently as possible. This minimizes heat transfer from the ambient air into the appliance. 

Remember to also keep your refrigerator level at all times, especially if it’s a three-way fridge. A level ground enables the coolant to flow efficiently to the right spots. 

10. Defrost Occasionally

All caravan refrigerators (whether three-way or compressor models) will accumulate ice over time. 

Now, ice buildup inside a fridge’s internal components is excellent news as far as preserving your food’s freshness. However, excess ice accumulation on the appliance’s cooling fins could have disastrous consequences. 

The ice could clog the fins and reduce their efficiency, leading to frequent cycling. 

To address this problem, be sure to defrost your refrigerator regularly by turning it off and opening the door.

Take A Smart Step Towards A Fresh and Chill Caravan Experience 

Keeping food fresh while caravanning isn’t just a question of taste and comfort. It can impact your overall health as well. 

According to the Centers for Disease Control and Prevention (CDC), 30-70% of travelers globally suffer from traveler’s diarrhea (TD). TD primarily stems from consuming stale or contaminated foods, underscoring the significance of properly preserving food while traveling. 

Implementing the above pointers can help to minimize these incidents and enjoy an adventure-filled caravan trip.
