Gas Fridge shares how propane refrigerators work with no moving parts

How does a propane fridge work? Gas Fridge would like to describe how propane refrigerators work - with no moving parts!

First the heat
Electric refrigerators use a coolant to keep the interior cold. In contrast, a propane fridge relies on simple chemical reactions. The process of propane refrigeration begins with a flame fed by a propane tank, which is why the appliance is called a propane fridge.

Every propane fridge contains a sealed network of tubes and chambers which hold water, ammonia and hydrogen gas. When a propane flame heats a chamber holding a solution of water and ammonia, the liquid begins to boil. Then the ammonia gas rises to another chamber, the condenser. In the condenser, the ammonia cools back into a liquid. This liquid then flows to the evaporator, where it mixes with hydrogen gas.

Then the cooling
 When ammonia meets the hydrogen gas, the chemical reaction between the two absorbs heat. In that way, the propane fridge produces its cooling action. Heat is pulled from the interior of the refrigerator into the ammonia-hydrogen mix. As heat is absorbed, the ammonia becomes a gas once again. The ammonia and hydrogen gases then combine with water. The ammonia and water form a solution yet again. That process releases the hydrogen gas to rise back to the evaporator. The process then starts all over again and is repeated continuously – all with no moving parts!

Among the many benefits of propane refrigerators, the fact that it has no moving parts means quiet operation and no mechanical issues. We proudly carry EZ Freeze gas refrigerators. We are so confident that EZ Freeze is the best product, we give you a 7-year warranty on the cooling unit and a 3-year warranty on the entire unit - the best warranty in the business.

Gas Fridge offers maintenance tips for gas refrigerators

A gas refrigerator is an important investment. As with any investment, there are maintenance requirements to get the most out of your gas appliance. Gas Fridge suggests these maintenance tips to increase the longevity of your gas refrigerator.

Proper cleanliness is important, especially on the inside of the refrigerator. A recommended and convenient time for cleaning your refrigerator is during the regular maintenance or right after defrosting.

To clean the inside:

• Use a soft cloth
• Use a mild soap and warm water solution
• Rinse the inside with a baking soda and warm water mixture of approximately 1-2 tbsp. to 1 qt. warm water.
• Wipe dry with a soft cloth
• NEVER use a coarse cloth for cleaning

For the outside:

• Clean the outside with the same instructions and products shown above for the inside
• Waxing the outside of the refrigerator box may prevent against minor scratches and add to rust protection
• Use a standard auto wax on the painted metal surfaces only. DO NOT use on the plastic handles or rubber gasket
• Always check the gasket surfaces for debris as this can cause a cold air leak from the interior.

Cleaning the absorption cooling unit will help with the unit’s overall efficiency. This should be done every three months. Simply use a large soft bristle brush and clean the dust and lint from the condenser fins (at rear top of cooling unit) and the coil pipes (at the bottom) .

Keep the area around and under the refrigerator clean. This will help prevent debris from being sucked into the burner tube. This is actually the most common problem with propane powered refrigerators not operating correctly. This should be done every three months.

A gas refrigerator is an important investment. The maintenance tips above will help to preserve your investment and keep your gas refrigerator operating properly.

In the event of a power outage, you can remain safe and comfortable if you have these important propane components recommended by Gas Fridge

Nearly all home appliances, whether heating, cooling or lighting, depend in some way on electricity to function. When the power grid goes down, our expensive appliances don’t help us. Like it or not, the power grid is one of the most important parts of our infrastructure, yet it is also the most vulnerable. It’s not only severe weather conditions that cause power outages, but now we have the more recent phenomenon of the cyber-attack. Gas Fridge shares how you can remain safe and comfortable even during a power outage with these propane appliances.

A Propane Generator. Propane fuel is available even if your gas pumps are not running, as it is stored in cylinders. The shelf life of propane is virtually limitless. Unlike gas generators, propane generators will not be full of contamination or carbon deposits even if they haven’t been run for a long time. A propane generator will get your power back quickly and dependably!

A Propane Refrigerator. You can still have safe, convenient food storage, no electricity needed, even in crisis situations. Propane appliances are a viable solution whenever you need modern refrigeration without electricity. You can rest assured that you are ready for any kind of emergency.

Gas-Fridge Discusses How a Gas Refrigerator Can Save You Money

Although the initial cost to purchase a propane gas refrigerator is a bit higher than an electric refrigerator, the long term costs should be considered, since there are a number of cost factors. Gas-Fridge would like to share some of the money-saving features of a gas refrigerator.

First, comparing an electric refrigerator with a propane refrigerator is like comparing apples to oranges. An electric refrigerator runs with Freon and a compressor to pump the refrigerant through the system. A propane-powered refrigerator operates with a propane gas flame to heat the ammonia and distilled water, using hydrogen gas to circulate steam vapor and liquid ammonia to cool it down. No electric lines or inverters and generators are needed to power the refrigerator.

• Comparing the operating costs of appliances that use fuels as different as propane and electricity is no easy task. The two fuels produce energy differently, they are measured and priced differently, and their energy is used differently by appliances. So a direct operating-cost comparison between a propane appliance and an electric appliance requires an understanding of energy cost, energy efficiency and appliance design.

• Let’s look at one of the long term cost differences: the energy needed to run the refrigerator. The first step in comparing the operational costs of appliances that use the two fuels is understanding how much energy each fuel contains per unit of measurement. Electricity is measured in kilowatt-hours, and propane is usually measured in gallons. A gallon of propane can produce the same amount of energy as 27 kilowatt-hours of electricity.

• The next step is to calculate the cost of an energy source per unit of measurement. For example, if the national average cost for residential propane is $3.08 per gallon, and the electric company’s baseline rate for electricity is 13.6 cents per kilowatt-hour, the 27-kilowatt-hour-per-gallon energy density of propane means it costs $3.67 to produce as much energy using electricity as it would cost to produce the same amount of energy using propane. As long as propane costs less than $3.67 per gallon, it's a cheaper energy source than electricity. Today's average rate for propane is about $ 2.36 per gallon.

The other cost-saving feature of a gas refrigerator is that it does not have moving parts like an electric refrigerator, which means in the long term there is less need for service and the appliance tends to last longer.

So the next time you are talking about getting a new refrigerator, consider the cost savings that could be realized with the purchase of a propane refrigerator - they’re not just for people living off the grid!

Gas-Fridge Compares Propane Refrigerators of Today and Yesterday

When compared to the SERVEL built in the 1930's -1950's which lasted for generations, the refrigeration units of today have become more streamlined with less heavy-duty materials for lighter weight and still have quality performance. Gas-Fridge, retailer of quality propane refrigerators, says an average propane gas refrigerator today will last approximately 15 yrs. By that time the box will be looking quite tattered under normal use.

The older style SERVELS were much heavier in weight weighing as much as 400- 500 lbs. The newer refrigerators weigh anywhere from 150-275 lbs. This again is due to lighter materials and higher quality workmanship. There is also a larger amount of selection available on the market to choose from today compared to 50 years ago.

The Servel brand was sold to Electrolux and then to the Dometic Corporation. The SERVEL name was still being used by DOMETIC until 2005. This refrigerator is now called a DOMETIC refrigerator which is still being produced by DOMETIC in Sweden. Some of the newer propane refrigerators for backwoods and off the grid living that are on the market today are: DIAMOND, EZ-FREEZE, DOMETIC, CONSUL, and DANBY. These are all ammonia absorption systems that run off of either, propane, natural gas, or butane burners. The DOMETIC refrigerator is the only one that is still available with kerosene

As was mentioned before, an average absorption cooling unit today runs for 10-15 years. The cause of this difference in length of performance compared to the older style SERVELS is based on 1 primary thing. When SERVEL built those huge old refrigerators, the materials used on the cooling units was so much heavier and thicker, thus adding all the extra weight, that they hardly ever rusted out. The evaporator was galvanized to prevent rusting. Rusting is a primary cause for leakage in the cooling units itself.

The gas consumption on a “modern day” gas refrigerator is less than half the amount than an older SERVEL is due to the designing of this cooling system. An average amount of propane used in the older SERVELS was 3-4 lbs. a day. This is approx. ¾ gal. of propane a day. The average amount that the newer style propane refrigerators use is 1 – 1 ½ lbs. a day through their more efficient operation. The amount of improvements that have been made in the newer style refrigerators [built from the mid 1970's - today] by improved performance in gas usage is credited wholly to the improved engineering on absorption cooling systems

Any propane refrigerator built in the 1980's until current are much cleaner to operate than the older SERVELS.  A new propane refrigerator does not generally need to be vented to the outside. However, If a homeowner is going to enclose his propane refrigerator in a kitchen with cabinets built over the top of the refrigerator and around the sides, it is always important to put a vent in the floor towards the back of the refrigerator and on the top of the refrigerator for ventilation so that heat can escape from the cooling system. If this is not done, a refrigerator may overheat, causing it to lose efficiency in cooling.

As you can see, modern technology has made huge improvements in the propane refrigerator of today. To learn more about propane refrigerator comparisons, contact the professionals at Gas-Fridge 928-636-6674 or visit our website at http://www.gas-fridge.com.
