With the cost of electricity raising what seems like almost every day many people are turning to older ideas to try to save money. One of these ideas is the propane refrigerator. They work on the idea of gas absorption. The newer models will typically last up to 25 years before needing a boiler rebuild.
Some of the best advantages for using a gas fueled refrigerator are more than just saving money. A propane fueled refrigerator is great for keeping most food cold when people are living off the grid, or other places that have no access to electric power. They typically have no moving parts in their cooling system so the parts do not wear out. They generally require little maintenance as well when compared to an electrical fridge.
Often the primary expense for purchasing a propane gas refrigerator is higher than an AC refrigerator would be, but this expense is easily recouped with cost savings from the food storage and its simplicity. Some newer models may use small 12 volt fans that are easily powered with a small solar array with a battery. The gas connection only needs a small 1/4 or 3/8 line for power.
If you do decide to make the green leap and get one you may have to know how to change out the cooling unit after the boiler is rebuilt on it. This same process can sometimes be adapted to different models for DIY conversions. While this process is easy enough, it is time consuming and this is simply and overview of the process. Always exercise caution when working on these units as the ammonia gas they use can be fatal if inhaled.
Take the fridge from where it is installed and place it some place where it is easy to get at. Make sure any gas line or electrical lines to it have been completely disconnected. Take off the door and take everything out including any food or shelves and wash it up with disinfectant.
Remove the aluminum plate which will give you access to all the copper pipes inside. Take out the screws or clamps holding any pipes leaving them loose. Set a blanket on the floor and put the refrigerator on the side so the piping in the back is easy to get to. Take out any screws holding the condensing coils, boiler assembly and the capillary tubes. Recheck your work making sure everything is loose.
Once everything is loose, get a pry bar and carefully pry the complete assembly free of the fridge. Use a cloth or towel to protect the copper you are prying on. You may have to cut some of the foam free to get it out. Keep all the screws and baffles because you will need them to reinstall the new unit.
Installation is generally the reverse of taking it out. Getting your boiler rebuild can be cheaper than buying a new unit. The key is ensuring the unit's cooling head is completely sealed and airtight. The freezer pipe should also be perpendicular with the cooling unit's back. Remember that these units use ammonia, so always practice good safety practices so your lines do not get punctured.
