FRIDGES FEATURE
The fridge is the most relied-upon appliance in an RV setup. Keeping your food fresh and beverages cold are imperatives for a fun trip. So much so, having more than one fridge is not unusual these days, particularly if you take the tow vehicle into account as well. In this article we will explore how they work, the various types of fridges available, the pros and cons and how to get the most out of them. As there are some complex concepts here, we have used a little repetition to reinforce the ideas.
HOW DO THEY WORK
At the most fundamental level, all fridges work on the same principle. They have two heat exchangers. One of the heat exchangers (evaporator) absorbs heat out of the fridge compartment lowering its temperature. Fridges often have two evaporators, one for the freezer compartment and another for the main fridge compartment. The other heat exchanger (condenser) dissipates heat into the air outside the fridge compartment. The heat exchangers do their thing thanks to fluid (refrigerant) that repeatedly flows between them via a closed loop of pipes. The refrigerant is pushed around the loop of pipes by a heat/pressure source. The net result is the fridge gets cool on the inside and hot on the outside. It is therefore necessary to dissipate this external heat to prevent the fridge from having to operate in an increasingly hot environment. This is achieved with ventilation
