What is a propane refrigerator and how does it work?
A propane refrigerator is an appliance that uses propane gas as its primary source of energy to cool and preserve food. Unlike conventional refrigerators that rely on electricity, propane refrigerators operate using a gas absorption cooling cycle. This cycle involves heating a refrigerant, which then evaporates and absorbs heat from the interior of the fridge, resulting in a cooler environment for food storage.
The main components of a propane refrigerator include the burner, evaporator, condenser, and absorber. The burner heats the refrigerant, causing it to vaporize and flow through the system. As the gas moves through the evaporator, it absorbs heat, cooling the interior. The cooled gas is then condensed back into a liquid form, and the cycle continues. This makes propane refrigerators an excellent option for off-grid living, camping, and areas with unreliable electricity.
