Understanding what an Absorption Refrigerator is, and why should choose Gas Fridge for your next EZ Freeze Refrigerator

What is an Absorption Refrigerator? It’s a lot simpler than you might expect. Gas Fridge is here to tell you all about Absorption Refrigerators and how to make an informed purchase when shopping for off the grid refrigerators.

What exactly is an Absorption Refrigerator? In an Absorption Refrigerator, the unit refrigerates itself by moving the hot air inside to the outside of the fridge. This process uses a sealed system containing a solution mixture of ammonia, water, sodium chromate, and hydrogen that is boiled by heat. The ammonia in the system is the main driving component, causing the change from liquid to gas, and back again. This pure ammonia liquid conducts heat away from the unity using aluminum plates on the back of the fridge. This system uses no moving parts at all and is accomplished using a combination of thermodynamics and the physical properties of gases.

The system is very specific in design, meaning a slight change in piping angle can lower performance and efficiency. A small solution ingredient difference will also change the gas refrigerator performance, as well as any weak welds will shorten the fridge’s life. Strict quality control is vital toward good production results. That’s why, at Gas Fridge ou

Defrosting your gas refrigerator - Helpful information from Gas Fridge

What’s for dinner? A common question that leads many people looking into the freezer, chipping away at frozen shelves of food, and trying to find something before frostbite sets in causing them to abandon their quest. Gas Fridge would like to discuss with you about defrosting your natural gas or propane refrigerator.

All gas refrigerators are manual defrost, why?

Those who have owned a newer electric freezer know of their auto defrost feature. In order to accomplish this, the unit’s defrost cycle includes timers and heating elements, this puts a large load on the electric supply. For this reason, the manufacturers of propane gas refrigerators elect not to include this feature.

Frost build-up inside of a refrigerator compartment is inevitable and will eventually lower the efficiency of any refrigerator. You will need to defrost your gas fridge manually. Depending on a few factors your application and time will help to determine when and how often the off-grid refrigerator will need to be defrosted.

How do I know when it’s time to defrost my Gas Refrigerator?

A non-electric refrigerator has aluminum cooling fins located on the back wall of the refrigerator compartment. Humidity collects on these fins and turns to ice. Monitor these fins and when the frost builds up between these fins to the point where there is no air space between the fins it is time to defrost.

The humidity in the air, number of door openings, and moisture on groceries will all contribute to frost build up and will vary depending upon the owner and climate. We find that a defrosting schedule can be as often as every 3 months or as little as once a year even within the largest propane refrigerator. EZ Freeze has developed a defrosting method that takes all of the work out of defrosting. It is as simple as turning a dial. The EZ-Defrost System is available on all models.

How does the EZ-Defrost System work?

The EZ-Defrost System includes multiple parts. First is a pan under the cooling fins inside the fridge compartment with drip spout that directs the water to a funnel mounted on the back wall of the fridge interior. The water then funnels out through the back wall and down into a removable tray on the rear of the unit. The tray is designed to either be removed and emptied or left in place where the water will evaporate due to the heated tray holder.

This is as close to automatic as it gets. In order to defrost, all you need to do is turn the temperature thermostat dial to a minimum setting in the evening and in the morning the frost in the fridge will be defrosted and drained through the above process. At this point in time all you need to do is turn the thermostat dial back to where it was prior to defrosting. No need to empty the contents of the fridge. No need to turn off the unit. No need to use a hair dryer or hot water to defrost. This is why we call it the EZ-Defrost System.

A little about maintaining your gas fridge or gas freezer – Information from Gas-Fridge

A gas fridge or freezer is a wonderful thing! For those people in remote locations without power, and areas prone to extended or unpredictable power outages, a gas fridge or freezer can be a life saver. Keeping food fresh or frozen makes life in remote locations easier and, during the winter months, the only real possible solution. Gas-Fridge brings you information on maintaining your gas fridge and freezer.

Because there are no moving parts in these gas refrigerators and gas freezers, there's not much maintenance needed. One very important thing you can do to keep the unit working to its maximum efficiency is to clean the flue periodically. The flue will soot up due to impurities in the gas. The dirtier the gas, the more soot will develop.

Getting started:

Cleaning the flue is simple. Turn the unit off and let the flue cool for a while. Place something over the burner orifice to protect it from the falling soot. Place a rag or piece of tin foil under the unit to catch any falling soot. Remove the baffles from the flue (if any). Be careful!! They may be hot. Use the Flue Brush and gently scrub the full length of the flue. Rotate the brush a few times to get all the soot possible.

One other common occurrence is debris in the burner air intake. If the gas fridge or gas freezer has been sitting for a while, spiders like the smell of propane and will make webs in the burner area and the unit will not light or burn with a dirty foul flame. Dirt, dust, pet hair, insects, lint, or anything migrating behind the gas fridge will increase the chances of the burning running foul.

Next step:

While in use, if the flame tip is yellow or orange, then chances are there is debris in the burner tube and air intake. It is very easy to remove. Turn the unit off. Using a piece of 1/4" flexible rubber hose, just aim it at the Air Intake of the Burner and blow through the other end to clean out the debris. Using compressed air or "air in a can" works well also. Be sure the unit is off and cooled before using "air in a can" since it can be highly flammable. Re-light the unit and visually check the flame. It should be a crisp blue flame with a white or yellow tip.

Continued maintenance:

Your refrigerator will give you years of trouble-free service if you do the following simple maintenance we mention above. To prevent debris from getting into the burner tube and creating most issues, it's a good idea to vacuum under and around your gas refrigerator or gas freezer often.
Checks every three to six months will help. Refer to the operator’s guide provided with your refrigerator for more details.

Adjusting the Temperature of Propane Gas Refrigerators - Gas Fridge

Most propane gas refrigerators end up in remote locations. Off-grid owners have more of a vested interest in keeping the refrigerator operating efficiently. Propane is usually trucked to the location or hand carried. Most rural off grid homes, cabins, and cottages don’t have automatic climate control. The off grid refrigerator is subject to a wider range of ambient temperatures during the day and during the seasonal changes. Gas Fridge has a few sets of instructions for adjusting the thermometer to help you economize your power usage.

Gas refrigerators are all manually temperature controlled (no digital thermostats or electronics).

Using the Fridge for the weekend only:
•    Allow 12 hours of chill down time for your gas fridge, if empty at 70°-80° room temperature.
•    Keep the door closed as much as possible – it’s tempting to look inside; at least know what you need before opening the door. Temperatures inside the fridge won’t fluctuate as often and your fridge will run more efficiently.
•    Don’t load the fridge with any food or liquids that are not already cold or frozen.
•    Set the temperature setting to maximum. If possible, set the thermostat to maximum and replenish the ice trays or drinks at night right before bedtime.
•    Now that the fridge is chilled down, load the groceries in smaller amounts at timed intervals (10 lb / 2 hours). Recovery times increase by three times, if all loaded items are not cold or frozen.
•    If all your items are cold or frozen, it’s okay to load all of them at once.
•    Liquid is more dense and takes longer to chill. 4 individual quarts of liquid chill faster than a one gallon container with liquid.
•    If you’re having extra guests or a party at the cabin, rely on an ice chest for cold drinks – this reduces the traffic to the fridge, keeps the door closed, and helps to keep the perishable items cold.

Using the fridge full-time:

•    Allow 12 hours of chill down time for your gas fridge, if empty at 70°-80° room temperature.
•    Keep the door closed as much as possible – it’s tempting to look inside; at least know what you need before opening the door. Temperatures inside the fridge won’t fluctuate and your fridge will run more efficiently.
•    Load the groceries in smaller amounts at timed intervals (10 lb / 2 hours).
•    Keep track of the refrigerators interior temperatures – the setting will affect the refrigerator compartment temperatures. (There is no setting for the freezer.)
•    The thermostat for the home type refrigerators is located at the bottom of the cabinet on the outside front, near or behind the kick plate.
•    If possible install a remote digital thermometer. This allows you to monitor inside temperatures without opening the door and it also has an alarm in case the gas supply suddenly stops working.

Stabilizing the temperature:

•    Start at the maximum setting.
•    Take a true reading first thing in the morning before the door is opened.
•    When the reading reaches 32°, slightly move the dial toward the minimum setting, 1/12 of a turn.
•    Ideally the temperature should be 34° - 38°.

Seasonal Changes and humidity levels will have an affect on demand and will produce more frost on the cooling fins. Food mass or a full fridge will keep the temperature more stable compared to an empty fridge with more air mass. Cold air from a fairly empty fridge will simply fall to the floor.
