A Propane Freezer, Gas Freezer or Propane Freezers
 for your weekend home, for your cabin or for you wilderness hide out, could be your most practical way of getting some ice cubes into your drink when you are ready for a cool down on a hot summer's day. Benefits of a Propane Freezer: Many people are discovering the benefits of a Propane Freezer. Also known as an absorption refrigerator, a propane freezer uses a propane burner instead of the electrically powered pump normally found in the standard electrical freezer. Among the benefits of a propane gas freezer is that it is portable and is available in a number of sizes. The RV propane freezer is popular among outdoor enthusiasts and more importantly is more environmentally friendly than its electrical counterparts. So key benefit is that a propane freezer does not need electrical power to function and therefore can be used off-the grid or wherever there is no electrical power. To understand fully the benefits of a propane gas freezer you need to know how it works. Ammonia is used as coolant in the propane gas refrigerator. A continuous refrigeration cycle is created using water, ammonia and hydrogen in the five main parts, namely the generator, separator, condenser, evaporator and absorber. A propane burner below the generator heats the water and ammonia. The temperature of the solution rises and eventually reaches boiling point, at which point it is carried to the separator via a pipe. In the separator, the water and ammonia are separated with the ammonia becoming a gas and rising upwards into the condenser and the water going into the absorber where it is stored for later use. The benefits of a propane freezer depend on this condenser which dissipates the heated ammonia and turns it back into its liquid form. The ammonia is then mixed in the evaporator with compressed hydrogen and forms a freezing vapour inside the freezer. There are a number of important benefits of a propane freezer. For one thing, they don't need cleaning as often as normal freezers, just once or twice a year is more than enough. Another of the benefits of a propane freezer is that it easier to maintain as there is no compressor unit and no batteries that need to be charged. It is in environmental terms though that the benefits of a propane freezer are most clear. Propane freezers or gas freezers are not dependant on electrical power and also don't contain the harmful substances that contribute to the greenhouse effect that many conventional fridges do. Because of the benefits of a propane refrigerator, the Propane Appliance Store offers a wide selection of gas freezers and propane freezer for your cabin or hide-out off the grid. A  Propane Freezer, Gas Freezer or Propane Freezers from The Propane Appliance Store will give you a reliable silent operation to meet your needs.
How does A Propane Freezer Work?
A Heated Gas Propane Freezer? You may not realize it, but modern Propane Freezers don't only cool things down, they keep things from getting too cold. Yes, you guessed it: Gas Freezers - Propane Freezer have onboard heaters/burners. They're low-wattage, but refrigerator heaters are very convenient and effective at doing everything from heating the evaporator coils to melt any accumulated frost, to keeping the butter chilled but not so cold that you'll need a chain saw to cut through it. Gas and Propane Freezer If you own an RV, chances are you have a gas- or propane-powered Freezer. These Freezers are interesting because they have no moving parts and use gas or propane as their primary energy source. Also, they use heat to produce the cold inside the Freezers. A gas Freezer uses ammonia as the coolant, and water, ammonia and hydrogen gas to create a continuous cycle for the ammonia. The Propane Freezer has five main parts: Generator - creates ammonia gas Separator - separates the ammonia gas from water Condenser - where hot ammonia gas is cooled and condensed to create liquid ammonia Evaporator - where liquid ammonia converts to a gas to create cold temperatures inside the refrigerator Absorber - absorbs the ammonia gas in water It works like this: Heat is applied to the ammonia and water solution in the generator. (The heat comes from burning gas, propane or kerosene.) As the mixture reaches the boiling point of ammonia, it flows into the separator. Ammonia gas flows upward into the condenser, dissipates heat and converts back to a liquid. The liquid ammonia makes its way to the evaporator where it mixes with hydrogen gas and evaporates, producing cold temperatures inside the Freezer's cold box. The ammonia and hydrogen gases flow to the absorber where the water collected in the separator in step No. 2 mixes with the ammonia and hydrogen gases. The ammonia forms a solution with the water and releases the hydrogen gas, which flows back to the evaporator. The ammonia-and-water solution flows toward the generator to repeat the cycle.

Heating Ammonia

  • Propane refrigeration works effectively in a cycle of heat, evaporation and condensation. A mixture of ammonia, water and hydrogen is stored inside a cooling unit. This unit is heated--using liquid propane gas so that no moving components are necessary--until bubbles containing small amounts of ammonia rise to the surface of the unit. This solution is passed through a tube called the siphon pump while the gas form of ammonia is sent to the water separator. Water vapor is condensed and directed back toward the cooling unit's boiling system while the actual dry vapor moves on to the condenser.

Ammonia Vapor

  • When ammonia vapor comes into contact with the air flowing above the condenser, it is condensed into liquid ammonia. This liquid ammonia is sent on to the evaporator, where hydrogen is passed over its surface. This lessens the vapor's pressure, causing it to evaporate. The temperature inside the refrigerator or freezer is lowered when the ammonia, as the result of this process, extracts heat from the food storage area. Afterward, the remaining mixture of ammonia and hydrogen vapor passes on to the absorber

Ammonia Solution

  • A continuous trickle of the ammonia solution is leaked into the upper part of the propane refrigerator or freezer where the absorber is located. It then takes up the ammonia (from the mixture of ammonia and hydrogen vapor). Remaining hydrogen, once separated, is left to rise through the absorber coil and back to the evaporator--in order to unmechanically repeat the process.

New Ammonia Solution

  • Detailed picture of the propane refrigerating/freezing process

    This stronger version of the ammonia solution flows down the absorber and back to the main cooling unit. The process can now repeat itself.

Important Notes

  • Free air circulation must be continued above the condenser and absorber tanks so that the heat may be correctly dissipated into the surrounding air. Heat must be maintained at the correct temperature--enough to boil ammonia--and with proper application so that the unit may function properly (beginning with heating the cooling unit).

Absorption System:
An absorption refrigerator is a  that uses a heat source (e.g., propane,solar, kerosene-fueled flame, waste heat from factories or district heating systems) to provide the energy needed to drive the cooling system. In the early years of the twentieth century, the vapor absorption cycle using water-ammonia systems was popular and widely used, but after the development of the vapor compression cycle it lost much of its importance because of its low coefficient of performance (about one fifth of that of the vapor compression cycle). Nowadays, the vapor absorption cycle is used only where waste heat is available or where heat is derived from solar collectors. Absorption Freezers are a popular alternative to regular compressor Freezers where electricity is unreliable, costly, or unavailable, where noise from the compressor is problematic, or where surplus heat is available (e.g., from turbine exhausts or industrial processes, or from solar plants). For example, absorption refrigerators powered by heat from the combustion of liquefied petroleum gas - propane - are often used for food storage in recreational vehicles and cabins, off the grid dwellings - propane refrigerator Absorptive refrigeration can also be used to air -condition buildings using the waste heat from a gas turbine or water heater.  This use is very efficient, since the gas turbine produces electricity, hot water and air-conditioning (called trigeneration). Both absorption and compressor refrigerators use a refrigerant with a very low boiling point (less than 0 F (−18 C)). In both types, when this refrigerant evaporates (boils), it takes some heat away with it, providing the cooling effect. The main difference between the two types is the way the refrigerant is changed from a gas back into a liquid so that the cycle can repeat. An absorption refrigerator changes the gas back into a liquid using a different method that needs only heat, and has no moving parts other than the refrigerant itself. The other difference between the two types is the refrigerant used. Compressor Freezers typically use an HCFC or HFC, while absorption Freezers typically use ammonia or water.

Absorptive refrigeration uses a source of heat to provide the energy needed to drive the cooling process. The absorption cooling cycle can be described in three phases: Evaporation: A liquid refrigerant evaporates in a low partial pressure environment, thus extracting heat from its surroundings – the refrigerator. Absorption: The gaseous refrigerant is absorbed – dissolved into another liquid - reducing its partial pressure in the evaporator and allowing more liquid to evaporate. Regeneration: The refrigerant-laden liquid is heated, causing the refrigerant to evaporate out. It is then condensed through a heat exchanger to replenish the supply of liquid refrigerant in the evaporator.

Propane Fuel Consumption
 
A typical 12 cubic foot propane refrigerator consumes an average 1.5 lbs. of propane per day, which works out to about 1,400 British thermal units of energy per hour or 32,225 BTU per day. Propane refrigerators are available as small as 4 cubic feet and as large as 18 cubic feet. Small units may consume well under 1 lb. of propane per day while large units may consume nearly 2 lbs. per day. Consumption also varies somewhat by brand. Running Time A standard 20 lb. propane bottle, widely available, provides 430,000 BTU of energy when full. At 32,225 BTU or 1.5 lbs. per day, that 20 lb. bottle will run your 12 cu. ft. propane refrigerator for 13 days. If you used two of these bottles, you would get around 26 days of running time. If you had access to larger propane bottles, you could run your typical 12 cu. ft. refrigerator far longer. A pair of 40 lb propane bottles would run your unit for 52 days, while a single 100 lb. bottle would run the appliance for 66 days.

Why Propane?
Propane Refrigerators running on propane or other fuels were introduced in the 1930s, when most of rural America lacked any electric service. Fuel-powered Freezers are still being produced by a number of manufacturers for sale to the Amish and others who choose to live without electricity, and for remote hunting lodges and vacation cabins located far from power lines. For remote dwellings used only seasonally, propane Freezers and other propane-powered appliances can be a viable alternative to bringing in electric power. How They Work A propane Freezer uses a sealed piping system containing a mix of ammonia, water and hydrogen. The propane flame heats a boiler filled with an ammonia/water solution. The heated solution bubbles up through a percolator pump, releasing hot ammonia vapor and returning the water to the boiler. The ammonia vapor rises to a condenser where it transfers heat to the room air and turns back into liquid. The ammonia liquid drains down into an evaporator filled with hydrogen gas that reacts with the ammonia to vaporize it again, drawing the necessary heat energy from the interior of the refrigerator. This cools the box and contents. The ammonia-hydrogen mixture drains down to an absorber chamber where the ammonia re-dissolves in water, releasing the hydrogen gas to rise back up into the evaporator. The water-ammonia solution drains down into the boiler to continue the cooling cycle.

Venting
Although propane is a clean-burning fuel, without enough combustion air, the flame releases carbon monoxide. This gas is invisible, colorless and odorless; it bumps oxygen out of the blood, damages major organs and could kill you. Since propane refrigerator burners are tucked away in an enclosed space, the burners must be supplied with sufficient combustion air, and exhaust gases must be vented outside. To do this, enclose the burner in a vented box, and position the outside exhaust vent well above the air intake tube; this will force rising hot gases to suck cold air down to the burner.

How to turn on a Propane Freezer
1-Locate the propane/electric switch on your RV's refrigerator. This is usually located on a panel on the top edge of the refrigerator, although in some models you may find it at the bottom.
2- Set the switch to "propane." The switch may be a dial type switch that you turn from one setting to another or it may be a button that is pushed to activate the propane refrigeration system.
3- Push in and hold the button labeled "push to start." This will be located near or next to the propane/electric switch.
4- While holding in the button, press the "ignitor" button. Look into the viewing window or prism on the control panel for a flame. Press the ignitor again if you don't get a flame the first time. When you see the flame, continue holding in on the "push to start" button for 30 seconds, then release. Check to be sure the flame is still burning--if it isn't, repeat the process.

How to Burb Propane Freezer
1-Shut off the electricity and gas running to the Freezer. Unscrew the connections to the gas and disconnect any wires.
2-Remove the screws holding the Freezer in place. Remove the refrigerator from its compartment.
3-Place the Freezer outside on level ground. Enroll the help of another person to avoid back injury.
4-Turn the Freezer on its side and leave it for two hours. Listen to the Freezer for the chemicals mixing together. Turn the freezer upside-down. Leave the Freezer in this position for 24 hours.
5-Carry the Freezer back into the RV. Secure the Freezer back in its compartment. Hook up the electricity and gas lines.
