How Does An RV Fridge Work?

Boil The Ammonia
The process starts with a vessel with water containing dissolved ammonia inside, as known as generator. The burner heats the generator until it reaches the ammonia boiling point. The ammonia leaves the generator and wafts up into the condenser because ammonia boils at a lower temperature than water does. Then, the ammonia starts to cool and forms liquid ammonia in the condenser, without water in it.
Cool It Down
The ammonia flows down from the condenser into the evaporator, a chamber filled with hydrogen with low pressure. In the evaporator, the ammonia expands and cooling rapidly. It is the fan on the evaporator that cools down the air as it blows past. Then, the cold air will circulate through the fridge.
Back to The Beginning
The absorber sends water trickling through the evaporator. While ammonia dissolves easily in water, the hydrogen is otherwise. Then, the water trickles down with the dissolved ammonia in tow and flows back to the generator, starting the cycle from beginning.

RV Fridge Tips and Tricks
When it comes to RV fridge, there are some things that you need to do to ensure the fridge always working properly. Below we write a few tips and tricks to keep your RV fridge running efficiently for a long time.
- Turn on the fridge the night before you hit the road. That way, the fridge gets to temperature and be ready to store the food.
- Store only frozen, cold and room temperature foods in your RV fridge. It’s because warm foods take much more time and power to cool.
- Leave space between the foods because a packed fridge restricts airflow that can cause food to cool unevenly.
- Get a battery-operated RV fridge fan, because it decreases the cool down time by 50%.
- Do not open the fridge too much because the temperature should always be 34 to 36 degrees to keep the food fine.
- Keep a thermometer in the fridge to know if it’s working properly or ready to store food.
- Defrost the freezer once or twice every month. Just turn off the fridge completely or put a pan of hot water in the freezer.
- Make sure the fridge is always in level position. As mentioned above there are RV fridges that can destroy itself if it’s put on uneven position for a long time.
- Run the fridge once in a while when you are not RVing. Because if the fridge isn’t running for a long time, the sediments in the liquid chemicals will settle on the bottom and clog.
- Park with the outside vent in the shade because the outside temperature affects how the fridge works.
- Keep things in place with expandable fridge bars.

1. Always keep the fridge door closed
When the coldness setting is on, the inside temperature of the appliance will gradually drop until it reaches the desired temperature. Thus, when the fridge door is open, it releases some of the coldness. Then, the inside temperature will go up several degrees and gains room temperature air from outside and it will take longer to get back to the previous temperature. As an alternative, bring a cooler and stash what you need for the day in there.
2. Avoid Fridge Gaps
Fill empty space with frosty treats such as cold cans, bottles, or small food items that can retail their coldness. Avoid using ice or anything that can freeze easily because it will melt somewhat. It would be a waste when the food thaws and go bad. Also when the ice melts, it makes the fridge leak.
3. Crank Up The Coldness
Turn the RV fridge to the coldest setting a day before your trip and leave it overnight. That way, when you unplug the fridge, everything inside will be ice.
4. Run A Generator
Power the fridge by hooking it to a generator. Afterward, make semi-frequent stops and let the generator running for a while. When using the generator, make sure never put it inside your RV because it releases fumes that can be poison. Keep the generator several feet away from the RV. That way, the fumes will filter into the air and not into your RV.
