The refrigerators manufactured by Whirlpool are the perfect combination of cutting-edge technology and ergonomic design. The company is reputed for using the latest technology to meet the requirements of the users.

Whirlpool refrigerators offer great features and are available in all kinds of budgets. If you want a refrigerator in affordable range, you can go for Whirlpool refrigerators. You can choose from direct cool, Frost Free and Frost Control range of refrigerators.

The refrigerators from Whirlpool are designed with latest innovations. One of their unique features is 6th sense frost control technology. Due to this technology, refrigerators defrost automatically. You need not spend your precious time over defrosting and cleaning it later. Due extended cooling option provided in these refrigerators, you can get better circulation of cold air in all the corners of the fridge.

To suit the Indian market, Whirlpool has introduced the Fusion series refrigerators. These refrigerators do not have the separate freezer option. That space is utilized for the food storage only. Though this may not suit the requirements of all the consumers but still there was demand of such type of refrigerators for long time.

Another feature in the cap is the unique ice making technology devised from Whirlpool only. This technology helps make the ice 30% faster than normal range. Then Whirlpool freezers retain the ice even in power cuts up to a certain period.

It can keep the ice as it is up to 12 hours in power cuts. Amazing! Due its unique features, Whirlpool is steadily making a place of itself in Indian market. As Whirlpool adapts itself to the market it is catering to, it has not initiated the twin door refrigerators in India because, people have more of food storing needs than freezing.

Using a Whirlpool Refrigerators is not at all expensive. There are many energy saving features in these freezers. You can save up to 30% of electricity usage due to energy saving feature of Whirlpool. This can reduce your ever mounting electricity bills.

Looks and style of Whirlpool Refrigerators are equally appealing. There is Swarovski crystal on the door handles giving them a unique look. There is wide range of colors to choose from. Among many reasons for buying a Whirlpool refrigerator; one is its after sales services. Whirlpool is known for its quick services and excellent customer care.

Robot Refrigerator

Although not a robot, Samsung is working on creating a refrigerator that will be the smartest refrigerator you will ever own. The reason for it being covered here on RobotsRule is because robots and A.I. (artificial intelligence) go hand in hand.

According to this Samsung spokesman Chae Hee-kook, the refrigerator will use RFID technology to track the items in your refrigerator. RFID stands for Radio-frequency identification. Tags are placed in many kinds of consumer goods that have RFID tags embedded in them allowing them to be tracked efficiently.

Using inventory levels set by the user, it will notify you when you are running low a particular item. Notification can happen in one of two intriguing ways:

1. The refrigerator will be able to send a shopping list of required groceries directly to your cell phone. So you may find yourself in the near future getting a call from you refrigerator instead of your significant other, asking you to pick some things up on the way home!
   
2. For participating grocery stores, it will be able to send your order directly to the store.

Given the second method, then theoretically if the store has a delivery service and your approval, you may find everything you need to make dinner tonight already waiting for you when you come home, without you having to do anything else but put the stuff away and cook it. Who knows, by the time the refrigerator is made available your home robot will do that for you! Other planned features include a recipe database that will suggest recipes based on what you have in the refrigerator, or will tell you what you need to buy if you want to make the meal for a recipe you like in the database.

Solar Power Refrigerator - A New Project

Refrigerators consume about 8% of the electric power used in American average homes and environmental temperature conditioning adds 44%. Most of these use electricity to generate the power required to operate refrigeration compressors but some use burning gas to obtain the energy to operate the refrigeration cycle.

There are about one hundred thousand portable refrigerators in use in the world which use kerosene for their power source. They are mainly used for vaccine storage in remote places without reliable electricity.

These flame powered refrigeration systems could be adapted to become solar powered refrigeration systems if the heated elements were exposed to concentrated beams of sunlight. A search of the internet didn’t come up with a permanent installation such as would be appropriate for a residential home or even an industrial setting but here at Greening the machine blog is a great site for saving energy.

The Tasman energy guy has some personal experience with various refrigerator systems and preferred the battery operated system powered by solar cells. Here the LPG Refrigeration Indonesia has several refrigerators based on gas which might be adaptable to solar use.

The diagram above is of the Hop-Hallstrom gas refrigerator designed in the 1920s and sold by Electrolux and discussed at greater length at Earth Garden.

To convert this to a solar powered system would only require a solar concentrator, such as a reflector, to concentrate the sun’s radiant energy upon the part labeled Generator-Boiler.

This adaptation could be ideally accomplished by exposing the generator-boiler located on the back of the refrigerator to the outside of the sun exposed side of the house and piping through the wall to a fully insulated compartment opening to the inside of the house.

A larger system of this type could be used for air-conditioning the entire house.

Comparing the Dometic and Norcold Cooling Units

The vertical pipe on the right in the photographs of these two refrigerator systems is the generator-boiler and in this photograph they seem to be discussing the electrical option of heating the working material within it.

As it is possible to use either burning gas or electricity to heat the material it would also be reasonable to use solar heat for that purpose. That would be easy enough to do if the columns were designed in such a way that a solar heatable surface were presented.

How Refrigerator Works? Another Explanation

The refrigerator in your kitchen uses a cycle that is similar to the one described in the previous section. But in your refrigerator, the cycle is continuous. In the following example, we will assume that the refrigerant being used is pure ammonia, which boils at -27 degrees F. This is what happens to keep the refrigerator cool:

1. The compressor compresses the ammonia gas. The compressed gas heats up as it is pressurized (orange).
2. The coils on the back of the refrigerator let the hot ammonia gas dissipate its heat. The ammonia gas condenses into ammonia liquid (dark blue) at high pressure.
3. The high-pressure ammonia liquid flows through the expansion valve.

   You can think of the expansion valve as a small hole. On one side of the hole is high-pressure ammonia liquid. On the other side of the hole is a low-pressure area (because the compressor is sucking gas out of that side).

4. The liquid ammonia immediately boils and vaporizes (light blue), its temperature dropping to -27 F. This makes the inside of the refrigerator cold.
5. The cold ammonia gas is sucked up by the compressor, and the cycle repeats.

By the way, if you have ever turned your car off on a hot summer day when you have had the air conditioner running, you may have heard a hissing noise under the hood. That noise is the sound of high-pressure liquid refrigerant flowing through the expansion valve.

Pure ammonia gas is highly toxic to people and would pose a threat if the refrigerator were to leak, so all home refrigerators don't use pure ammonia. You may have heard of refrigerants know as CFCs (chlorofluorocarbons), originally developed by Du Pont in the 1930s as a non-toxic replacement for ammonia. CFC-12(dichlorodifluoromethane) has about the same boiling point as ammonia. However, CFC-12 is not toxic to humans, so it is safe to use in your kitchen. Many large industrial refrigerators still use ammonia.

In the 1970s, it was discovered that the CFCs then in use are harmful to the ozone layer, so as of the 1990s, all new refrigerators and air conditioners use refrigerants that are less harmful to the ozone layer.

Confused about the Refrigerator Parts-Here is a Clear Explanation

What is a refrigerator made of?
Here are the major components of a refrigerator:

Compressor

Heat-exchanging Pipes

Expansion Valve

Refrigerant

Confusing! What are those parts?

A Compressor is a mechanical device used to compress or compact something. In the case of the refrigerator it is the refrigerant.

The Heat-exchanging pipes are the coiled set of pipes inside and outside the refrigerator. You can usually see this by looking on the back of the fridge.

The expansion valve allows the refrigerant to change its pressure by expanding a small pipe into a big one.

The refrigerant the liquid that evaporates inside the refrigerator to create the cold temperatures. This liquid in the past was ammonia or a chlorofluorocarbons (CFCs).

Ammonia is used because of its extremely low boiling rate. It boils at -27 degrees Fahrenheit or -32 degrees Celsius.

Now days ammonia is no longer used because it stinks, and CFCs are no longer used because of ozone depletion. CFCs have been banned from use by the Kyoto protocol. 134A is now used in most fridges today.

Introduction to Refrigerator

In almost every home in America maybe even the world, there is a refrigerator. This marvelous machine that can keep many things cool and preserve food.

With out a refrigerator much of our food cooked and not cooked would go bad in a short while. On many refrigerators there is also a freezer to keep stuff frozen and preserved even longer then the refrigerator can.

Refrigerators these days are getting larger, more organized chock full of great features like water dispensers and ice machines.

We really can take a refrigerator for granted sometimes. Just take a look back and see what they had to do to keep food good. Meat had to be salted in-order to be kept it edible. Cold drinks on a hot summer day were a luxury for most people.

Freezer is the one who, or that which, cools or freezes, as a refrigerator, or the tub and can used in the process of freezing ice cream.
