Almost in every home there is a refrigerator. The refrigerators which we are having at homes are more cost effective, efficient and they are having long life also. But the refrigerators that we use in home run on electricity. That’s why those refrigerators don’t work if we live in area where there is no electricity or go for camping. For such type of conditions there are other types of refrigerators which are called gas powered refrigerators. Gas powered refrigerators works on the places where electricity is not available.

How Gas Refrigerators Work?
Gas powered refrigerator’s basic components are same like the electric refrigerators such as:
-
Generator
-
Separator
-
Condenser
-
Evaporator
-
Absorber
These components work together, uses the gas as both fuel and coolant to make the refrigerator work when there is no electricity available. The whole process is effective, as its less energy efficient than the standard refrigerator. But it works effectively. Read the full story

You might think that if you live in an area where there is no electricity available, you will be deprived of many basic facilities such as the use of refrigerators or air conditioners. But the good news is that there are still options available such as a gas or propane powered refrigerator.

These refrigerators are very interesting, as they have no moving parts and use gas or propane as their main source of energy. They build up and maintain the cold temperature inside the refrigerator by burning propane and using the heat.
A gas refrigerator uses the following:
- Ammonia as a coolant
- Water
- Ammonia and hydrogen gas to maintain a continuous cycle for ammonia.

The basic working of a refrigerator is quite similar to that of an air conditioner. Except that in the case of a refrigerator, there is an insulated box present to contain the things and maintain temperature inside.
Evaporation In Refrigerator
As it has been described in the earlier articles, a refrigerator uses the concept of evaporation of a liquid to absorb heat. When you put some water on your skin, it evaporates by taking the heat from your body and making you feel cool. If you put alcohol on your skin, it will make your skin feel even cooler as it evaporates at a lower temperature as compared to water. And the liquid used in a refrigerant evaporates at an extremely low temperature enabling the refrigerator to keep things cool and create freezing temperatures inside.
If you put some refrigerator’s refrigerant on your skin, it can freeze your skin as it evaporates (Don’t try to do it). Thus it is mainly due to the evaporation of the refrigerant that the things kept inside the refrigerator are kept cold. The heat from these things is carried by the refrigerant and a steady cold temperature is thus maintained.

Main Parts Of Refrigerators
Similar to an air conditioning system, a refrigerator also has five main parts:
