The next chapter in RV cooling

Absorption technology has helped generations of motorhome and caravan travellers and continue to serve specific travel needs well. At the same time, changing vehicle designs, growing battery capacity, the rise of solar-ready systems, and changing travel needs are making compressor refrigeration an increasingly relevant choice for today’s motorhomes and caravans.

Absorption and compressor refrigerators explained

Absorption refrigerators are flexible systems because they can run on 12V, 230V or gas. Unlike a household refrigerator, they do not use a compressor. Instead, a heat source, powered by gas or electricity, drives a cooling process that lowers the temperature inside the refrigerator. This process also releases heat, which is why exterior ventilation grilles are an essential part of the system.

Compressor refrigerators work in a way that is more familiar to most of us, as the technology is like the refrigerator we use at home. They run on electricity, usually from the vehicle’s 12V battery system. A compressor circulates refrigerant through the cooling system, while the evaporator absorbs heat from inside the refrigerator. This allows the interior to cool down quickly and efficiently.

The main differences between absorption and compressor refrigerators:

Shift to compressor refrigerators

Today, compressor refrigeration is becoming more relevant because it fits naturally with the direction of modern leisure vehicles. As manufacturers work with increasingly stronger battery systems, solar preparation and more electric-ready layouts, appliances are evolving with them.

There are also benefits for vehicle design and energy use. As compressor refrigerators only run on electricity, no gas systems or pipes are needed. They also do not require an outside ventilation grille, giving manufacturers more flexibility in vehicle design and creating a cleaner exterior look.

For travellers, this shift brings many practical benefits too. The fast, stable and reliable performance of compressor refrigerators helps keep drinks cool and food fresh, even in warm weather. Compressor technology also requires less technical space inside the refrigerator compared to absorption technology, creating more usable shelf space for everyday groceries. And because compressor refrigerators are not sensitive to vehicle tilt, travellers have more freedom to stop and stay at uneven locations.

Some concerns from the past, such as noise and limited off-grid capability, are becoming less relevant thanks to quickly evolving technology. Modern compressor refrigerators are increasingly efficient, which helps reduce noise and energy use. At the same time, the rise of lithium batteries and solar-ready systems makes longer off-grid stays more realistic than ever.

Thetford’s role in this shift

‘’Absorption refrigeration has served the market well for many years and will remain a logical choice for many travellers in the years ahead,’’ says Dennis van den Berg, Product Manager RV/OEM at Thetford. ‘’Now, with a clear electrification trend and travellers looking for flexible energy use, compressor refrigeration is gaining relevance. Our role at Thetford is to offer a diverse portfolio that serves all leisure vehicle travellers, now and in the future.’’
