EMKARATE

What is EMKARATE???

The Emkarate family of lubricants is a wide range of polyol ester refrigeration oil products. They are designed specifically for use with HFC refrigerants, developed to meet the performance demands of the refrigeration industry. This superior performance is achieved with basefluids that are specifically formulated to deliver optimum performance with minimal additive levels.

he requirements of today’s refrigeration and air conditioning compressor lubricants are complex. They must be compatible and miscible with the HFC refrigerants, and they must be compatible and miscible with CFC’s and HCFC’s as well as mineral and alkylbenzene oils. Polyol ester lubricants meet these needs, and the EMKARATE RL line is the preferred choice. Working in close collaboration with compressor and system manufacturers, these OEM-approved POE lubricants cover a wide viscosity range from 7 cSt (35-40 SUS) to 220 cSt (1100 SUS) to suit most applications. The lubricants have excellent thermal and chemical stability, and are compatible with a wide range of elastomers, polymeric materials and other materials of construction. Additionally, then higher viscosity index is an indication that their effective viscosity will not change drastically with the wide swings in temperature seen by most typical refrigeration and air conditioning systems. They are the preferred choice for servicing and retrofitting existing equipment as well as for OEM charging.

Inetresting Facts on the Refrigerator

Inetresting Facts on the Refrigerator

History

The refrigerator was invented by Jacob Perkins in 1834. The original liquid used as a coolant was ammonia, which killed many consumers. Freon was later used. Early refrigerators were made with a wood cabinet and a compressor. As advances were made, steel and porcelain became more common. The basic demand for a refrigerator occurred because humans needed a reliable source of cooling for their food because ice was unreliable.

Mechanics of a Refrigerator

In older fridges, a coolant known as freon or chloro-fluoro-carbon was pumped through tubing. A pump pushes the liquid through the tubing, which evaporates. This evaporation removes the heat from the refrigerator and freezer, thus causing it to become cool. In newer fridges a gas called HFC-134a is used. A compressor pressurizes this gas, and it heats up. The gas is forced through a very small opening called an expansion valve. It loses pressure and returns to a gas. As it cools in the tubing, it pulls the heat out of the refrigerator compartment. The cold gas is then pulled back up by the compressor to start the process over again.

Styles of Refrigerators

Most consumers are familiar with the basic design of a fridge. You are not limited to these designs. A variety of custom designs are available. A transparent fridge exists which is completely clear, and all the contents inside can be seen. It is a big seller in Japan. A fridge has been designed with a built-in beer dispenser. For the college student, a modular fridge is available; several small fridges are stacked on top of each other so each student has his own private fridge.

Energy Savings

Replace your old fridge. If you have an out-of-date fridge purchased in 1980 or earlier, you can save yourself $50 a year, as of January 2011, simply on energy savings. In fact, a fridge made in 1993 or earlier can cost an average of $110 each year in electricity. Buying an Energy Star labeled refrigerator can save on your utility bill. Old inefficient refrigerators and freezers in the U.S. cost the American consumer about $4.9 billion dollars of extra expenses each year.

Life Expectancy

On average, the life expectancy of a refrigerator is 14 years. Homes in the U.S. contain about 44.5 million fridges that are over 10 years old. Many of these units serve as secondary units to a household. If each home replaced its old, inefficient fridge with a new Energy Star certified unit, consumers would save $2 billion a year in utility costs and enough energy to light up 9.2 million homes for a year.

refrigeration system

Mechanical Refrigeration Systems

The first patent for mechanical refrigeration was issued (1834) in Great Britain to the American inventor Jacob Perkins. Mechanical refrigeration systems are based on the principle that absorption of heat by a fluid (refrigerant) as it changes from a liquid to a gas lowers the temperature of the objects around it. In the compression system, which is employed in electric home refrigerators and commercial installations, a compressor, controlled by a thermostat, exerts pressure on a vaporized refrigerant, forcing it to pass through a condenser, where it loses heat and liquefies. It then moves through the coils of the refrigeration compartment. There it vaporizes, drawing heat from whatever is in the compartment. The refrigerant then passes back to the compressor, and the cycle is repeated.

Prior to 1996, the refrigerants used in electric refigerators were chlorofluorocarbons (CFCs). However, because of increasing scientific evidence that the CFCs are harmful to the ozone layer of the stratosphere, they were banned by international treaty, the Montreal Protocol, after Jan., 1996. Transitional compounds, such as hydrochlorofluorocarbons (HCFCs), which are less harmful to the ozone layer, are to be used in their place until the year 2020. By that time compounds such as the hydrofluorocarbons (HFCs), which are benign to the ozone layer, are expected to have replaced HCFCs.

In the absorption system, widely employed in commercial installations, ammonia is usually used as a refrigerant to cool brine (water containing calcium chloride or sodium chloride) that is then sent through pipes to cool the refrigerated space. The steam-jet system is used where temperatures below 32°F (0°C) are not required; water is used as the refrigerant. Airplanes are cooled or heated through an air cycle system. Research and development is being carried out to apply the Peltier effect (see thermoelectricity) in various practical refrigeration systems.

warehouse

WAREHOUSE

A warehouse is a commercial building for storage of goods. Warehouses are used by manufacturers, importers, exporters, wholesalers, transport businesses, customs, etc. They are usually large plain buildings in industrial areas of cities and towns and villages. They usually have loading docks to load and unload goods from trucks. Sometimes warehouses are designed for the loading and unloading of goods directly from railways, airports, or seaports. They often have cranes and forklifts for moving goods, which are usually placed on ISO standard pallets loaded into pallet racks. Stored goods can include any raw materials, packing materials, spare parts, components, or finished goods associated with agriculture, manufacturing and production.

Polyolester oil

Polyolester oil

Polyolester oil, commonly called POE oil, is a type of Synthetic oil used in refrigeration compressors that is compatible with the refrigerants R-134a, R410A and R-12. Its recommended by experts as a replacement for HFC's. Along with R134A mineral oil its recommended as a replacement for R12 mineral oil as R134A does not mix well with mineral oil. These wax free oils are sugggested for usage with chlorine free HFC systems as they provide better lubrication and stability and are more miscible with HFC refrigerants. They can meet the lubricity requirements to those of mineral oils used with CFC's and HFC's. They are compatible with most lubricants in the market. It is noted that the viscosity of the oil increases with temperature. the dispersion behavior of this oil has also been the subject of a lot of study. it is also considered by some to be a good additive to engine oil

fact

What is Refrigerant and its properties?

REFRIGERANT:    A heat carrier must be use to move heat from the interior of a cabinet or room to the outside. Thus in refrigerating system fluids which absorb heat inside the cabinet and release it out side are called refrigerant. The ideal refrigerant would be one that could liberate all the heat that it is capable of absorbing. The refrigerant changes from liquid to vapor during the process of absorbing heat and condenses again to liquid while liberating heat in most of the refrigerating systems.

PROPERTIES OF A GOOD REFRIGERANT: The properties of a good refrigerant for commercial use are:

· it should be nonpoisonous.

· it should be non explosive

· it should be non corrosive

· it must be nonflammable

· Leaks should be easy to detect.

· Leaks should be easy to locate.

· It should operate under low pressure.

· Part moving in the fluid should be easy to lubricate.

· It should be nontoxic (not harmful if inhaled or if spilled on skin).

· It should be a stable gas.

Don't Treat Today's Refrigeration 

Systems with Yesterday's Techniques

Today's refrigeration technicians are confronted with refrigeration systems that are vastly different than those serviced last century, but they still continually use the "tried and true" repair/maintenance techniques that used to be very effective.

The hydrofluorocarbon (HFC) refrigerants and polyolester (POE) oils of today's systems have different chemical make-ups than their predecessors--hyrdrochlorofluorocarbon (HCFC) or chlorofluorocarbon (CFC) refrigerants and mineral oil. Essentially the new refrigerants are more stable than the old refrigerants, but the oils are less stable.

Grandpa probably wanted nothing but refrigerant and oil in his refrigeration systems, but today's service technicians don't have that choice. The new refrigerants and oils for the 21st Century already have many built-in additives that were never present in the old refrigerants and oils.

The chlorides used in the CFC refrigerants had excellent anti-wear characteristics. Unfortunately chlorides are one of the reasons CFC refrigerants have been deemed bad for the environment. To fill the anti-wear void created when chlorides were eliminated from the new HFC refrigerants, oil manufacturers put in phosphorus and other additives. Plus there is a full range of aftermarket products that a service technician is enticed to add into a system. Generally, additives within a system fall under three different categories:

Additives that are built into today's new HFC's by the refrigerant and oil manufacturers that promote lubricity and anti-wear. These additives usually get consumed during the life of the unit resulting in sludge formation and increased wear or oxidation over time that damage the system.
Additives that are not intentionally added to the system, but get into the system during the manufacture or installation of the equipment. (such as acid, air, or moisture)
Aftermarket additives introduced by a technician that remain in the system and increase the formation of sludge or alter the equilibrium chemistry of the oil.
In general, the refrigerant and oil manufacturers have ensured that their proprietary compositions of additives are compatible within each other. However, combining these chemical additives with acid neutralizers, untested flushing fluids or leak stopping chemicals is a recipe for disaster. Many technicians also fail to realize that water and air in a system is more of a problem with the new synthetic oils.

refrigeration cycle

Refrigeration cycle 

A sequence of thermodynamic processes whereby heat is withdrawn from a cold body and expelled to a hot body. Theoretical thermodynamic cycles consist of nondissipative and frictionless processes. For this reason, a thermodynamic cycle can be operated in the forward direction to produce mechanical power from heat energy, or it can be operated in the reverse direction to produce heat energy from mechanical power. The reversed cycle is used primarily for the cooling effect that it produces during a portion of the cycle and so is called a refrigeration cycle. It may also be used 
In the refrigeration cycle a substance, called the refrigerant, is compressed, cooled, and then expanded. In expanding, the refrigerant absorbs heat from its surroundings to provide refrigeration. After the refrigerant absorbs heat from such a source, the cycle is repeated. Compression raises the temperature of the refrigerant above that of its natural surroundings so that it can give up its heat in a heat exchanger to a heat sink such as air or water. Expansion lowers the refrigerant temperature below the temperature that is to be produced inside the cold compartment or refrigerator. The sequence of processes performed by the refrigerant constitutes the refrigeration cycle. When the refrigerant is compressed mechanically, the refrigerative action is called mechanical refrigeration.
There are many methods by which cooling can be produced. The methods include the noncyclic melting of ice, or the evaporation of volatile liquids, as in local anesthetics; the Joule-Thomson effect, which is used to liquefy gases; the reverse Peltier effect, which produces heat flow from the cold to the hot junction of a bimetallic thermocouple when an external emf is imposed; and the paramagnetic effect, which is used to reach extremely low temperatures. However, large-scale refrigeration or cooling, in general, calls for mechanical refrigeration acting in a closed system. 

FRIDGE FACT

SOME MORE FRIDGE FACTS

Fridge Fact:
The first household refrigerator produced by General Electric in 1911 was based on a design by a French Cistercian monk and physics teacher named Marcel Audiffren. The monk’s sulfur dioxide refrigerating process took the form of a wooden refrigerator named the Audiffren. It cost $1000, which was twice as much as an automobile.
Fridge Fact:
Freon was the primary refrigerator coolant for many years. However, Freon has been banned as a refrigerator coolant because of its ozone depletion potential. The newer coolants are known by the acronym HCFC, which stands for hydrochlorofluorocarbon, plus a number. Two refrigerator coolants in current use are HCFC-22 and HCFC-142b.
Fridge Fact:
Older refrigerators must be disposed of properly because of the environmentally damaging materials they contain. Old refrigerators with Freon coolant and CFC-bearing insulation are of particular concern. To ensure your old refrigerator is disposed of safely and legally, contact your local utility company or locate an appliance recycler in your area.
Fridge Fact:
A crisper is a refrigerator drawer or compartment used to keep vegetables and fruit fresh and “crisp” (thus the name). Crispers work by maintaining humidity levels suitable for fresh vegetables and fruit. For healthier and better tasting produce, choose a refrigerator that has a crisper with separate temperature and moisture controls.
Fridge Fact:
In 2006, nanotechnology researchers at the University of Alabama and Belgium’s Hasselt University proposed an idea for the world’s smallest refrigerator. Known as a Brownian refrigerator, the molecular-scale device would theoretically be used to keep nanoscale machines cool and control temperatures during molecular biology experiments (it would be far too small for leftovers).
Fridge Fact:
Most people have a refrigerator magnet or two. Louise J. Greenfarb of Henderson, Nevada, has over 32,000 different refrigerator magnets. She is appropriately known as “The Magnet Lady.” Her collection was declared the world’s largest by the Guinness Book of World Records. Over 7,000 of her magnets can be seen at the Guinness Museum in Las Vegas.

fact

Fridge Fact:

A refrigerator typically accounts for around 10% of a home’s power bill. About 1/3 of a refrigerator’s cold air can escape when the door is open, which is why a closed door keeps energy costs down. So does using energy-efficient appliances: an ENERGY STAR refrigerator uses less power than a 75-watt light bulb.

Fridge Fact:

Salt water, commonly known as brine, is sometimes used as a food preservative and refrigerant. Medieval peoples discovered that brine absorbs heat as it evaporates, and placed containers in brine to keep them cool. In America, meatpacking got its name in the 118th century because workers packed meat into brine barrels.

Fridge Fact:

November 14th is National Clean Out Your Refrigerator day. Fresh foods should be kept only one to two days in a refrigerator. Cooked meats can be stored for three to four days. To keep food longer, wrap it in airtight foil or plastic wrap after use and store at a temperature below 40 degrees F.

Fridge Fact:

Did you know that Albert Einstein co-invented a refrigerator? He and his former student Leo Szilard received a patent for it in 1930. Coolants used at the time could be toxic, and Einstein got the idea for a simple, single-pressure absorption refrigerator when he read about a sleeping family killed by leaking refrigerator coolant.

eco friendly gas

R134a refrigerant – is it really Environmentally Friendly?

Sure it may have a “0″ ozone depletion rating so why is the Australian Government and other nations going to “ban” it and phase it out by 2015?
The simple answer to the question is that it may have a “0″ ozone depletion rating but the other side of that coin has not been exposed sufficiently. Like most things there’s a downside to R134a. To start with it has a global warming rating some 1300 times higher than carbon dioxide. Sure the refrigerant it replaced (R12) had higher ratings and sure R12 needed to go but was R134a the right choice and did we know the long term effects R134a was going to have and now is having on our environment?
And now with the reports coming out on the increases in component production costs (including the cost to the environment), the high compressor failure rates with R134a as opposed to R12, and the fact that it does have a global warming rating that is too high to continue using it, one has to wonder why anyone would buy a product today that claims R134a as “environmentally friendly” when it’s really “ozone friendly” but highly “global warming unfriendly”.
We’re going to be again shelling out big money within the next couple of years to replace a refrigerant that was sold as the “Big Saviour” of our environment. And has it really reduced or even helped to reduce the ozone depletion rate or did all the associated production and manufacturing of new components, materials and wastage just offset the real benefit?
And no one mentioned that R134a only has a usability life span of 14 years. So what are we going to do with all that recovered R134a refrigerant? Even though it was never labeled as flammable, it actually is highly flammable and toxic when it burns. If there was ever any measurable benefit from the use of R134a will that all be lost in the destruction of this very same gas?
So we can agree that R12 had to go but it had a cost of less than $10 AUD per kg and now we pay over $100 AUD per kg for R134a so what’s it going to cost for the next refrigerant replacement that is going to save our planet? One thing you can take to the bank is the cost of getting rid of the” Big Saviour” R134a is going to be built into the cost of the new kid on the block.
So who’s the big winner out of all of this? You can bet it’s not us the consumer and is there a real benefit to our environment? Just follow the money trail and if you’re not sure where that trail starts I would suggest the refrigerant council of Australia and benefit to the environment… yeah to the benefit of the chemical companies banking environment!
Is there a real answer to the protection our environment? Yes of course there is and we already have had the answer for many many years. The reason why these tried and proven technologies were not pushed? Simply there was no money in it for the chemical companies and all the hangers-on that jumped on the band-wagon and started hollering… the sky is falling the sky is falling, who also cashed in big time but now the cracks are showing up in the hype.
So the next time someone tells you that R134a is “environmentally friendly”… they clearly have no idea what they’re talking about and they are just blowing global warming gas out of their ___! You can fill in the blanks!

refrigerant

A refrigerant is a substance used in a heat cycle usually including, for enhanced efficiency, a reversible phase transition from a liquid to a gas. Traditionally, fluorocarbons, especially chlorofluorocarbons, were used as refrigerants, but they are being phased out because of their ozone depletion effects. Other common refrigerants used in various applications are ammonia, sulfur dioxide, and non-halogenated hydrocarbons such as propane.Many refrigerants are important ozone depleting and global warming inducing compounds that are the focus of worldwide regulatory scrutiny.
