The “Not So Cool” Story of Refrigeration

Imagine a modern home without a refrigerator? Well, it’s hard to even think what we would do without refrigeration. Modern cities in developed countries depend heavily on refrigeration to keep perishable food items fresh and safe for daily consumption. The technique of refrigeration has impacted agriculture, industry and lifestyles across centuries evolving from ice harvesting to temperature controlled rail cars.

Refrigeration is the name given to the process that ‘removes heat from one location to another’ creating a cool or cold environment that has many applications like household refrigerators, air conditioning systems, cryogenic facilities and industrial freezer units.

The idea of cooling beverages has its origin in the ancient Chinese and Roman empires. Seasonal harvesting of snow and ice is a practice dated prior to 1000 B.C. according to a collection of Chinese lyrics from the period known as the Shih dynasty. whirlpool ice magic pro The next mention of ice harvesting is in the time of the Jews and is mentioned in the book of Proverbs in the Bible. Other civilizations such as the Egyptians, Greeks and Romans made use of large snow pits lined with tree branches and chaff to cool beverages and keep fruit cool. But it was not until the Persian culture when the usage of an ice pit called Yakhchal is mentioned; this may be the precursor to cold storage of food for preservation.

In the early 1800s, ice became a mass-market commodity with a large majority of people using ice boxes to store dairy products, fish, fruits, meat and vegetables, thus paving the way for the acceptance of refrigeration technology.

Refrigeration – the timeline

William Cullen, a Scottish professor was the first to examine the idea of artificial refrigeration by creating a partial vacuum over a container of diethyl ether that absorbed heat from the surrounding air. This was in 1755 but the experiment had no practical application at that time.

In 1758, professors Benjamin Franklin and John Hadley investigated the principle of evaporation as a means of rapidly cooling an object by conducting an experiment at Cambridge University.

In the year 1820, renowned British Scientist Michael Faraday used high pressures and low temperatures to liquefy ammonia and other gases.

American scientist Jacob Perkins working in Great Britain in 1834, assembled the first ever closed-cycle vapor compression refrigeration system. Although the prototype, not patented, was the first known system to function successfully, it did not have any commercial success.

American physician John Gorrie made a similar attempt in 1842 but again it was a commercial failure.

The first patented, practical vapor compression refrigeration system using alcohol, ether or ammonia came in 1856 built by James Harrison.

In 1860, Ferdinand Carre of France patented his gas absorption refrigeration system design referred to as “aqua ammonia”, the process of using gaseous ammonia dissolved in water.

Meanwhile, an engineering professor at the Technological University Munich in Germany had been working on an improved method of liquefying gases. In 1876 he patented this new process which was made possible by using gases such as ammonia, sulphur dioxide and methyl chloride as ‘refrigerants’, a practice that began to be widely used until the late 1920s.

A refrigerant is a substance or chemical used in a heat cycle, as in the case of refrigeration, to convert liquid into gas.

By the turn of the 19th century, refrigeration came to play a vital role in the food distribution industry first through natural ice and then on manufactured ice. Many food and meat packing houses in America adopted ammonia-cycle refrigeration units for their storage facilities.

With the idea of artificial refrigeration a huge success, came the thought of refrigeration for household purposes. The limitations were largely on account of size as they were designed for installation on lorries, truck and storage houses and the safety factor in case of fire accidents where toxic gases leaked or exploded.

Refrigeration for the home

In 1911, General Electric (GE) became the first company to overcome the challenges of meeting refrigeration needs for the home. GE released a household unit powered by gas that eliminated the need for a motor and considerably decreased the size of the unit. However, the idea of a gas-powered unit did not go down well with electric customers of GE so an electric model framework was set into operation.

In 1927, Monitor Top, the world’s first ever refrigerator to run on electricity was released. The idea created waves with many other companies hitching their bandwagon in the run-up to improve upon this new invention.

One of GE’s main competitors, Frigidaire entered the fray in 1930, synthesizing Freon as a refrigerant. This was a breakthrough invention that enabled the development of cheaper, lighter and smaller refrigerators for home use. At that time the use of Chlorofluorocarbon (CFC) was considered to be less harmful than the more commonly used refrigerants like ammonia, methyl chloride and sulphur dioxide. The intent was to provide safer home equipment at affordable prices.

Nowadays, home refrigerators have become stylized home appliances with a variety of designs, colors and sizes with varying temperature control functions to cater to the needs of small, medium and large families.

Easy Air Conditioner Maintenance Tips That Could Save You Lots Of Cash

Air conditioners are very important to have around during summer. The hot weather can become very unbearable and disturbing. There are 2 main air conditioning units you can use to improve the condition of your surroundings. There is the central unit system that can cool down large spaces in a very short time. Unfortunately, they are expensive and require a high level of maintenance. The second type is the mini air conditioning system that can easily be moved around. They are cheaper than traditional ACs and are more effective because they can be used for other things.

One of the major benefits of this type of air conditioner is its portability. It can be moved from one place to another conveniently. This means that even if you do not have coolant system in your entire house, you can still afford to bask in cool weather. Unlike the traditional system that can only be installed in a particular place. The movable air conditioner can be taken anywhere you want. You can use it in your home office during the day and take it into the kitchen when you want to whip a meal or prepare a snack. Besides, this appliance is very handy for cooling down desktop computers, laptops, musical equipment and severs that always have the probability of heating up.

Another benefit of a mini air conditioner is that it does not take a toll on your electric bill at the end of the month. When you always use your central or permanent air condition system, its heavy reliance on electricity shows at the end of the month when you get your bill. The electrical current required to power the big units easily surpass a small conditioner. It is really a waste of time, when large conditioners are used for cooling places that are not used often or inhabited. It helps to be financially prudent and cool off only the places that are required sometimes. A portable air conditioning system helps you to achieve just that. lg dual inverter ac 1.5 ton 5 star

The multi-use features of a small air conditioner cannot be under estimated. It clearly gives you a bang for your buck. Most small air conditioners come with special settings that allow you to not only use them in a hot climate but also humid weather as well. The unique feature sucks in the humidity in the air and leaves your room cool, refreshing and dry. This is a plus for people who suffer from allergens like dust mite and mold. In addition, these portable ACs come with washable filters which offer you impressive health advantages by filtering the air around you.

These ACs are available in beautiful colors and can conveniently blend in with your surroundings. They are compact and do not need an excessive amount of space. They can be easily installed. You do not require the services of a technician. Moreover, you do not need to blow a hole in the wall to pass something through.

William Hill Casino – New Gladiator Slot Machine and 66 Pounds Free

Having spent the weekend in Las Vegas, I had a chance to engage in one of my favorite forms of Las Vegas entertainment, playing the penny and quarter slot machines.

I just about doubled my modest $25 ‘investment’ and kept myself thoroughly entertained for a couple of hours. By Las Vegas standards, that was a good ROI.

It got me wondering about the allure of slot machines.  I think it has to do with the suspense of the ‘hunt’ and the thrill of the win. It’s a similar dynamic.

“How do I find my best prospects?”


“What does it take to win them over?”

If you treat your business like it’s a slot machine though, you could be suffering from some serious problems.

1. Feeling like you’re not in control
2. Trying lots of strategies but unsure which ones will really work
3. Worried about if and when your big payout is going to happen

Here are 5 ways to win at business and improve your sales, revenue and profitability.

1. Focus on your core strengths

Many people suffer from the I-have-lots-of-strengths-interests-and-abilities syndrome.  I grapple with this one sometimes myself.  You may find that you’re afraid to focus because you’re worried you’ll be leaving dollars on the table.

Actually, the opposite is true.  The more you focus, the easier it is for people who need you to find you.  So define what you do best and organize your business slot gacor  around that.

2. Know who you best serve

Similarly, many of my clients are reluctant to select a target market thinking that they’ll make less money if they don’t do everything all of the prospects in the world need.  Again, not true. Trying to serve to many people will keep you scattered, spreading your efforts too thin.

It’s easier to find specific groups of people and it’s easier to market and sell to them because you can say all of the right things that will grab their attention.

3. Listen to your clients & prospects

In order to grab their attention, you have to be speaking their language and this requires that you know what they’re talking about.  A lot of business owners make the mistake of creating products and services JUST because they’re good at it without knowing if the market is at all interested.

4. Understand their pain

When you listen deeply to your prospects and clients, you can learn what keeps them up at night.

You’ll get a visceral experience of how they’re suffering and where you can help.  You can better empathize with them and show your concern for their situation in a more authentic way.

5. Offer solutions to conquer their pain

Once you know the things you excel in, who most needs you and what their problems are, you’ll be able to offer them the perfect antidote to their dilemma and they will thank you for it while eagerly snapping up your products and services.

When you follow these 5 steps, you’ll be more strategic about your business, you’ll stop dropping coins in any random slot machine and your payout of more and bigger sales will just happen naturally.
