What is a Propane Refrigerator?

Most of us are familiar with various propane appliances that are used for heat, light, or cooking. A propane refrigerator, on the other hand, is not quite so well known. What is a propane refrigerator, and how does it work?

Interestingly enough, the cooling process that allows a propane refrigerator to work begins with generating heat. Employing a boiler system that causes ammonia to bubble and rise, passing vapors into a condenser. Air circulating over the condenser removes the heat, which causes the vapor to condense into liquid ammonia, where it flows into an evaporator. It is here that hydrogen passes across the ammonia and causes it to evaporate. This process extracts heat from the inside of the unit, where food would be stored, creating a cooler area.

Just as with conventional electric powered refrigerators, the propane refrigerator will come in different sizes. This will also impact the amount of propane needed in order to keep the unit working properly. As an example, a propane refrigerator with a 5.6 cubic feet cooling area would consume in the range of up to three gallons of propane a week.

Many propane refrigerator models also will operate on electricity as well as propane, although typically are not as energy efficient. This versatility makes them ideal as a backup system if your area experiences frequent power failures. Also, the units may ideal for a fishing cabin or other structure where electricity is not available.

Just as with any appliance, these refrigerators are certified and tested before being sold to the public. Manufacturers provide operating instructions and suggestions for general maintenance. Currently, there are some of these refrigerators on the market that look almost exactly like a conventional refrigerator. You can even pick a color other than a standard white.

Cooling food has always been a problem in situations where electricity is not a viable option. With the advent of the this refrigerator, the consumer has a great solution to that problem.
