Refrigerators are an indispensable part of modern life. Frost forms around the cooling coils of the freezer when the water vapor touches the cold coils. If the frost is allowed to build up, it can get very thick and there would not be enough space for food stuff. The earlier models required manual defrosting but the newer ones are frost free which has lessened the labor of maintaining the refrigerator.

The frost free refrigerator basically has three components, like the timer, heating coil and a temperature sensor. All three work in tandem for the smooth automatic defrosting of the refrigerator. The heating coil is turned on by the timer every few hours or so. These coils are entwined among the freezer coils. The heat melts the frost off the coils and when all of it is melted the sensor turns off the heat as soon as the temperature goes above 32 degree F. This is how the whole process of defrosting basically works.

In most of the frost free refrigerators the cooling coils are within the freezer compartment. The heater is either woven into or set on these coils. The timer normally is found at the back of the compressor in the older models but the newer ones may have them in front of the refrigerator or inside it.

Earlier, the timer would go off for defrosting whether it was required or not. But, heating the coils at every six hours or so would consume a lot of energy. But, now, with energy reserves depleting at an alarming rate and energy-efficiency being the norm, the latest frost free refrigerators have timers which are controlled electronically and are called adaptive defrost control.

The period of defrosting is not fixed. The component is programmed to take into account the usage of the refrigerator and the time it takes for the coils to be defrosted. The device then calculates the necessary time required and adapts itself accordingly.

Frost free refrigerators have certainly made life simpler. With manual refrigerators, one had to be constantly on the vigil to prevent the refrigerator from frosting all over. It needed the emptying out of the entire contents of the refrigerator and then letting the frost melt over a couple of hours or so. Then the messy draining and dripping of water had to be taken care of. The full refrigerator had to be wiped dry, the contents put back again and only then could the refrigerator be re-started.

Some really older models required overnight manual defrosting for the entire frost to melt away. This was especially tedious as the food had to be either consumed totally or some way had to be found to keep it fresh under the circumstances. The whole process was labor-intensive and time-consuming. One had to be physically present to do all this work. Now, no one has the time to do so much actual physical labor and thanks to advanced technology, we are rid of the tedium of manual defrosting.

Frost free refrigerators are easier to clean and maintain and they also have the upper hand as far as energy saving is concerned. A properly designed frost free refrigerator uses less energy than the cyclic defrost ones which have to be manually defrosted. Also, the price of these frost free models is not very much more than the direct cool ones. Frost free refrigerators are an integral part of the modern, busy lifestyle now and there scarcely will be a household which does not possess one.

Propane refrigerators can help you save energy and reduce carbon footprint without diminishing your lifestyle.

Propane refrigerator uses gas as its basic source of energy. It uses heat for burning propane that will generate the cold inside the refrigerator. You can also use this kind of refrigerator where there is no electricity available in your place. This type of refrigerator applies ammonia as the coolant and the water, ammonia and hydrogen help in the continuous cycle.

The refrigerator has five main parts that have a correlation with one another to make the refrigeration process become efficient.

• The Generator that produces ammonia gas.

• The Separator is where ammonia gas is separated from water.

• The Condenser is where hot ammonia is cooled and compressed to produce liquid ammonia.

• The Evaporator is where the liquid ammonia evaporates to produce cold temperature inside the fridge.

• The Absorber sops up the ammonia gas in water.

The refrigeration cycle using propane works like this:

• The heat coming from burning gas, kerosene, or propane is utilized in the generator.

• The generator has a solution of water and ammonia that when heated, raises the temperature to the boiling point of ammonia.

• This boiling solution will flow to the separator that will separate the water from the ammonia.

• The ammonia gas will emerge upward to the condenser that will allow the ammonia gas to disperse its heat and concentrate into liquid.

• Fluid ammonia will now proceed to the evaporator where it combines with the hydrogen gas and then evaporates and this will eventually produce cold temperatures within the refrigerator.

• The hydrogen and ammonia gases will surge to the absorber. The water that has been collected in the separator is combined with ammonia and hydrogen gas and then it will flows back to the evaporator. And this ammonia and water solution will run towards the generator to go over the cycle.

• Propane refrigerator is one of the alternatives for costly electrical refrigerators.

Here are some useful tips in purchasing propane refrigerator:

• Consider the cost and the capacity of the refrigerator you need. Propane refrigerators come in different sizes - from 8 to 19 cubic feet. The location and gas consumption will also affect your decision.

• Select the type that will suit your needs. Some of these propane refrigerators can be modified to work on either electric or kerosene fuels.

• Keep in mind the accessories in your purchase of propane refrigerator. Some of these types of refrigerator require a glass shelf or deli drawer accessories. It may also come with doors and it’s up to you to decide if you will install it left or right handed.

• Study all the product brochures on different brands for comparison.

• Know about the warranties and expanded service contracts. You really need to understand what is the coverage of the warranty and if it is incorporated with your purchase or it has an extra cost.

• If you already liked a model that appeals to you, look around for the most reasonable price.

When using propane refrigerator, always be extra careful because it is highly flammable. Be sure to read and follow instructions and precautions when it comes to using and storing propane tank when it is not used. With propane refrigerator there are a lot of possibilities where you can use it like in your RV, boats, when you are on a camping, cabins and vans.

Choosing a good fridge is not only about to buy an expensive one, you have to decide about its quality, system and energy saving function. How to choose a good fridge can be described as follows;

1. You should choose the fridge that large enough for all of your family members. For family that has only 2 persons the 2.3 ft3 is the suitable size. The size of the fridge should be increased correspond to the additional person in your family, 1 ft3 for 1 additional person.

2. Choose only the fridge that has heat resistant pad that thick enough to protect the cold leaks out and to save energy.

3. Be aware that a two-doors fridge consume more power than ones that has single door, because the two-doors model uses longer cold transmission pipe.

4. The fridges that has automatic no-froze system will consume for power than the ones that has semi-automatic no froze system.

5. If you have to choose the fridge that uses 110-120 voltage (in some countries may have different voltage power supply), don’t for get to ask electricity adaptor. Please also noted that using with adaptor will consume more power.

Use refrigerator to save energy

1. Before use, read entire manual completely and make sure that you understand all detail in manual

2. About the location, you should locate the fridge at least 15 cm away from the wall. Put the fridge a bit away from the wall will increase effective ventilation.

3. Avoid locate the fridge near equipments that generate heat, such as oven, stove and also avoid to locate it against sun light.

4. the slope of the floor is also important, if you adjust the slope of the floor which will make the fridge is a bit lean backward, the fridge’s door will automatically close after use.

5. Always check the quality of all rubber seals, which the cool may leaks out.

6. Do not open the fridge too often, and close the fridge’s door quickly after use.

7. Often use the auto froze system to make sure that there will be no ice in the freeze tray.

8. Adjust the temperature suitable for each type and quantity of food in the fridge.

9. If you have to go away from your house for long time or there are no stuff in the fridge, you can unplug it until you sue it again.

Using a fridge safely

1. Install ground cable attached to the fridge and plug. If you did not install ground wire, switching the plug anode may reduce the quantity of electricity leak

2. Use screw driver to test whether the electricity leaks out (use type of screw driver that can test the electricity leaks)

3. If possible, choose the fridge that has automatic power cut and resume operation. This will help when your house has power short or uncertain power shortage.

4. If the lamp in the fridge is broken, do not remove it until you have a new one to replace

5. Do not let the area around the fridge wet, it could be danger if your fridge has power leaks.

6. Always remember or take note on emergency numbers.

psymom asked:


We are remodeling our kitchen and putting in a half bathroom. The toilet and corner sink will be black. (The washer and dryer will also be in the same room.) The room is located in the “wealth”/ “health and family” areas of the house. With the black toilet and sink, I thought about doing a Mary Englebreit kind of decor. I would like to do something whimsical, but if that’s not “feng shui” enough for the location of the bathroom, I would love to hear some ideas. (I’m pretty sure that we are already starting with bad feng shui with the bathroom being right next to the kitchen!)Thanks in advance for any ideas!
