Compressor vs. Absorption RV Fridge: Which is Best?

Planning a road trip in your RV or a camping adventure and wondering if a compressor or absorption refrigerator is the right choice for your needs? This question concerns many outdoor enthusiasts, as both cooling systems have their advantages and disadvantages. In this article, we’ll explain the differences between compressor and absorption refrigerators so you can make an informed decision. Connecting a Refrigerator in an RV, after all, requires careful consideration.

How Compressor and Absorption Refrigerators Work

Let’s start with the basics:

Compressor refrigerators work similarly to your refrigerator at home. A refrigerant circulates in a closed system, changing between gaseous and liquid states. The evaporation of the refrigerant extracts heat from the interior and releases it outwards. A compressor ensures the necessary circulation of the refrigerant.

Absorption refrigerators, on the other hand, use a physical principle where a water-ammonia solution is heated. The resulting ammonia vapor is circulated through a system, re-liquefies, and cools the interior in the process. Unlike compressor refrigerators, absorption refrigerators do not require moving parts, but merely thermal energy, which can be supplied by either gas or electricity.

Advantages and Disadvantages of the Two Cooling Systems

So, which cooling system is right for you? That depends on your individual needs and the type of trip you’re planning.

Compressor refrigerators are known for their high cooling performance and energy efficiency, especially at high outside temperatures. They cool down quickly and can even freeze items. Another advantage is their independence from ambient temperature. However, they are usually slightly more expensive to purchase and can be a bit noisier due to the compressor.

Absorption refrigerators, on the other hand, score points with their low noise level and flexible power supply, as they can be operated with gas, electricity, or a combination of both. This makes them ideal for camping trips where a reliable power source isn’t available. However, their cooling performance is highly dependent on the ambient temperature, and they require more energy compared to compressor refrigerators.

“Compressor refrigerators are the best choice for travelers who value high cooling performance and energy efficiency, while absorption refrigerators impress with their flexibility and quiet operation,” according to Dr. Ing. Markus Wagner, expert in refrigeration technology at the Technical University of Munich.

Making Your Decision: Which Refrigerator is Right for You?

Here’s a summary of the most important criteria:

Compressor Refrigerator:

Advantages: High cooling performance, independent of ambient temperature, energy efficient
Disadvantages: More expensive to purchase, a bit noisier

Absorption Refrigerator:

Advantages: Low noise level, flexible operation with gas or electricity
Disadvantages: Cooling performance dependent on ambient temperature, higher energy consumption

Also consider the following factors when making your decision:

Travel Destination and Climate: In hot regions, a compressor refrigerator is the better choice.
Trip Duration: For long trips, an energy-efficient compressor refrigerator is advantageous.
Power Supply: Will you always have electricity available on the go, or are you reliant on gas?
Budget: Absorption refrigerators are generally less expensive to purchase.

More Tips for Choosing the Right Refrigerator

Pay attention to the size of the refrigerator and choose a model that meets your needs.
Inform yourself about the refrigerator’s energy consumption to avoid unpleasant surprises.
Read reviews from other users to learn more about the pros and cons of different models.
