How does the refrigeration process work in a gas-operated RV fridge?

The refrigeration process in a gas-operated RV fridge works by utilizing a process called absorption refrigeration. This system mainly involves three key components: ammonia, water, and hydrogen gas.

First, the fridge contains a solution of ammonia and water. When the RV fridge is turned on, a burner heats this solution. The heat causes ammonia to evaporate from the solution.

Next, the ammonia gas travels through a series of tubes to a condenser. In the condenser, the ammonia gas cools down and transforms back into a liquid state. This cooling occurs because the ammonia releases heat to the surrounding air.

Then, this liquid ammonia flows into an evaporator. In the evaporator, the liquid ammonia absorbs heat from the fridge’s interior. This process cools the inside of the fridge, thereby keeping stored items cold.

Simultaneously, the remaining water in the system mixes with the hydrogen gas. The hydrogen gas helps to maintain low pressure in the system, facilitating the ammonia evaporation process.

Finally, the ammonia and water solution returns to the generator, where the cycle begins again. The combustion of gas provides the energy needed for this entire cycle, ensuring effective cooling inside the RV fridge.

In summary, the gas-operated RV fridge relies on heating ammonia, which evaporates, condenses, absorbs heat, and creates a continual refrigeration cycle.
