Refrigeration, Ozone, and Greenhouse Gases

Refrigeration, Ozone, and Greenhouse Gases

ozoneFrom the refrigeration installation experts in St Louis near Fenton MO, we decided to bring information your way regarding synthetic refrigerants and the environmental aspect of their use, as well as natural refrigerants we have been researching out of pure interest and intrigue. First, what are they, and what are some basic facts as gathered by your Refrigeration Sales in St Louis MO near Fenton?  “Synthetic refrigerants such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) have a negative impact on the earth’s atmosphere. The CFCs and HCFCs destroy the protective ozone layer so that the sun’s aggressive ultraviolet rays can reach the surface.”  Further than that, we found in our research on behalf of your Refrigeration Installation and Repair near Fenton, that this radiation can cause genetic damage in the cells of people, plants and animals.

This would be the reason for the international Montreal Protocol starting the phase-out of ozone depleting substances in 1987. With success: According to the latest  scientific assessment by the World Meteorology Organization and UNEP the ozone layer could recover to a large extent by 2050.  This conclusion is worth passing on as we uncover the final remarks on behalf of your St Louis Refrigeration Maintenance near Fenton.

The ozone-friendly successors came about, and unfortunately, still have their woes.  You see, the also synthetic hydrofluorocarbons (HFCs), contribute to global warming up to 4,000 times more than CO2. Even though they are specified as greenhouse gases under the Kyoto Protocol, they are still widely used in refrigeration appliances. The concentration of greenhouse gases in the atmosphere is at an all-time high and the contribution of HFCs is growing.  Stay tuned to other posts from this source where we work to uncover more details on behalf of your Refrigeration Repair in St Louis near Fenton MO, including natural refrigerants and the possible gain from their use.

Refrigeration Interest Climbs Exponentially

Refrigeration Interest Climbs Exponentially

interestedRefrigeration has many facets of interest in the real world as the global appetite for refrigeration is growing at an unprecedented rate according to experts.  On behalf of your St Louis Refrigeration sales near Overland, we bring you some of the details to back up the facts. Not only is there increasing demand for commercial refrigeration for food storage and transportation, but the domestic refrigeration market is also booming according to the sales of area refrigeration retailers in and around St Louis MO. “In mature, saturated regions like North America, home refrigerator and freezer sales are primarily driven by replacement. In emerging markets such as the Middle East, Latin America and China, the growth is spurred by a new, more affluent middle class demanding modern appliances and improved food quality and variety.” To back this up is the fact that in India, for example, purchase of home refrigerators grew by double digits last year alone.

The rapidity with which the market continues to grow has consequences, according to much that we read on behalf of your St Louis Refrigeration Repair near Overland.  “This rapid and continued growth has serious economic and environmental consequences. With the increase of refrigeration units in use comes the corresponding increase in energy consumption and environmental impact.” We can do the math by counting the approximate 1.4 billion domestic refrigerators and freezers in use worldwide, each with an annual average consumption of 450 kWh.

If we look at this from a different angle, on behalf of your St Louis Refrigeration Maintenance near Overland MO, home refrigeration units consume 649 TWh annually all together, which is equal to the entire energy consumption of the American Midwest, including Illinois, Indiana, Michigan, Ohio and Wisconsin, for one year. And, these numbers are expected to climb, as the global appetite for refrigeration continues to increase.

Variable Speed Compressors

Variable Speed Compressors

compressorThere is a definite global need and initiative to conserve energy.  This, combined with mitigating climate impacts is and has been putting pressure on manufacturers to design new ways to continue energy efficiency measures and reduce damage to the ozone layer all at the same time.  According to the research done on behalf of your St Louis Refrigeration Sales and Service, “This pressure is driving an uber-trend of sustainability in the refrigeration industry and has led to some truly innovative solutions and breakthrough technologies, especially in the design and production of compressors.”

Variable speed compressors are just one example of the above.  They tend to be extremely flexible and provide tremendous energy efficiency. Your St Louis Refrigeration Sales and Repair know that they are designed to adapt the cooling capacity according to the refrigeration need and are capable of working in any energy grid worldwide, regardless of the voltage and/or frequency being used. Thanks to the development of an intelligent electronic inverter, variable speed compressors are possible.  They have sensors that identify the temperature inside the cabinet and send signals to the compressor to change its speed to reach the target temperature much faster. Because a variable speed compressor cools according to need, it consumes 40% less energy than a conventional compressor, thereby accomplishing the combined goal of energy efficient and highly functional in refrigeration.

Looking at these compressors from a global view, it is apparent that variable speed compressor usage is trending globally and is already well established in many developed countries that are more focused on energy efficiency than others. “For example, approximately 90% of compressors currently in use in Japan are variable speed. In 2011 there were six million variable speed compressors in use around the world; by 2018 it is estimated that number will be 23 million. This is good news for the environment and for consumers.”

From Salt to Freon in Refrigeration

From Salt to Freon in Refrigeration

refrigerationWhen it comes to refrigeration, there is vast history in its making and it, like many other modern day technologies, hasn’t been around forever, nor has it always provided the same level of efficiency and function.  As we learned previously, salt was an ancient form of meat preservation and actually worked.  “Salting food was a common preservation method before the invention of refrigerators.” Bacteria cannot survive in salt, so rubbing dry salt on food or covering it in a salt solution called brine can help keep meat and other foods from spoiling. The actual earliest form of refrigeration was seen by the few people who had the advantage of an icehouse to cool their food to preserve it.

In the early 30’s, Freon came to be.  According to our research on behalf of your St Louis Refrigeration Repair near Clayton MO, the biggest concerns surrounding Freon were environmental.  There was definitely proof that it was not the best thing for our environment and so scientists worked to modify and help minimize the potential damaging effects.  As a result, mandates and chemical make-up of Freon has evolved over the years.

Today, just about all American households and businesses have a refrigerator. It saves a ton of time in preserving foods, making it much more practical and convenient for our modern day, demanding lifestyles.  The food being preserved, according to your St Louis Refrigeration Maintenance near Clayton, is allowed to remain safe and edible for much longer periods of time as well.  “Because of the number of refrigerators used in homes, businesses, and transporting food and supplies, there is a significant need for trained professionals who can repair and maintain this equipment. HVAC technicians are well-versed in refrigeration technologies as it cools and dehumidifies. When these systems are in need of repair, they require knowledge in the theory behind the systems and knowledge in how the equipment runs to be able to fix it.”

 

History of Refrigeration

History of Refrigeration

refrigerationThe history of refrigeration is one topic we have been meaning to explore for a while now, and so, on behalf of your St Louis Refrigeration Repair and Sales near O’Fallon MO, we will start discussing that very subject today.  There have been many changes in the way refrigeration works over time.  Salting food was a common preservation method before the invention of refrigerators. Bacteria cannot survive in salt, so rubbing dry salt on food or covering it in a salt solution called brine can help keep meat and other foods from spoiling. “Some people had the advantage of an icehouse to cool their food to preserve it, which was the earliest form of a refrigerator.”  According to our efforts in research on behalf of St Louis Refrigeration sales near O’Fallon, we know that GE came up with the first refrigeration that not all people could necessarily take advantage of due to cost.

“After General Electric produced the first electric refrigerator in 1911, the wealthiest Americans could afford the luxury of having this new invention in their homes. Other people used an icebox to preserve their food.” An ice box was a costly alternative, according to Refrigeration sales and service in St Louis, because so much water had to be used and frozen. After freezing it, the ice had to be cut, stored and finally, delivered.  In the 1930’s is when Freon was first put to use inside refrigeration.

Progressing down the timeline on behalf of your Refrigeration sales in St Louis near O’Fallon, we find that after WWII, refrigerators were produced in mass quantities, making them affordable and widely available in the US. They popped up with new features like automatic defrosting and icemakers. “Combination refrigerator and freezer units were immensely popular. Throughout the 1970s, 1980s and into the 1990s, environmental concerns over the use of Freon were debated and studied. Because of its estimated effect on the environment, the government put tight restrictions on the use of Freon in refrigeration equipment.”

Ice and Thermal Driven AC Technology

Ice and Thermal Driven AC Technology

iceThermally-driven air conditioning is the next new technology that we wish to discuss further on behalf of your St Louis Refrigeration Sales near South County MO.  “Chromasun, based out of North Sydney, as in Australia, makes a thermally-driven chiller that provides a low-cost alternative to conventional air-conditioning units, which are electrically driven.”

That seems like a lot to wrap your head around, but essentially these chillers make use of solar energy that, when running short, can be supplemented by natural gas and that lends itself to a greener route and also adds significant value to our discussion about renewable energy in the St Louis Refrigeration Sales world. The company mentioned above makes it own solar panels that generate a high enough temperature to drive a double-effect chiller, which it describes as its most effective system. According to our most recent research on the subject on behalf of your St Louis Refrigeration Service near South County, the company’s double-chiller system is said to provide more cooling than comparative photovoltaic systems, and eliminates electricity costs.

Another cool concept is the ice powered air conditioner. “Ice Energy, based out of Glendale, Calif., uses an ice-powered air-conditioning unit called the Ice Bear to cool buildings and in most cases, reduce a building’s total net energy consumption.”  Keeping up as best we can on the latest technology, your St Louis Refrigeration Maintenance and Sales near South County found the following information worth sharing for green HVAC and Refrigeration evidence in our neck of the woods.   “In a very abbreviated description, the Ice Bear works by freezing 450 gallons of water in a tank overnight and making that available for cooling the next day. When the Ice Bear is switched from its Ice Charging to Ice Cooling mode, it provides cooling for up to six hours. After its ice has melted, the job of cooling reverts back to the building’s conventional commercial A/C unit, which is why the Ice Bear works in conjunction with a conventional unit. The company describes the product as the first effectively loss-less energy solution.”

Commercial Refrigeration Brand Decision

Commercial Refrigeration Brand Decision

brandWhether you are buying your first one or setting out to replace what you already have, buying restaurant equipment, such as commercial refrigeration in St Louis near O’Fallon MO, can be a hassle that leaves you frustrated to say the least.  There are some basic tips that we intend to share, when it comes to shopping for your St Louis Refrigeration near O’Fallon, we hope it helps ease the process.  In this post, we cover the importance of putting some stock in the brand of refrigeration you choose.

Be aware of the brand. “Like most products you buy, your commercial refrigerator’s brand matters. There are a lot of manufacturers out there, so it’s important to zero in on a manufacturer you know you can trust.” There will be different commercial refrigeration brands focused on a variety of things.  Some will be quality focused, but may also be higher priced.  Others will be value focused with the price being the most affordable part, but may sacrifice some features or quality.

According to the research we did on behalf of your Refrigeration Sales and Service in St Louis, the following is true, “Bottom line: every manufacturer has its niche. True, Turbo Air, and Delfield are three well-known and trusted names in the refrigeration biz that are worth putting your stock in.” Don’t forget that each of the brands deemed safe bets, also often have used models floating about that are worth consideration.  “Because these brands are trusted to last a long time and are of such high quality, it is often beneficial for restaurants to purchase them as pre-owned equipment. This will save you money, while not compromising quality.”  Most places, like your Refrigeration Sales in St Louis will also guarantee their sale of whichever refrigerator you buy for a minimum of 30 days or longer.

Refrigeration History Elaboration

Refrigeration History Elaboration

historyDid you know that the Chinese harvested ice from rivers and lakes as early as 1.000 BC in the name of primitive refrigeration?  They even had religious ceremonies for filling and emptying ice cellars. That’s not all.  Hebrews, Greeks, and Romans placed large amounts of snow into storage pits and covered it, insulating material like grass, chaff, or branches of trees. They actually used these pits as well as snow to cool beverages, according to our recent research on behalf of your St Louis Refrigeration Maintenance near Sunset Hills MO. “Egyptians and ancient people of India would moisten the outside of the jars and the resulting evaporation would cool the water that was inside of the jars. The first group of people to use cold storage to preserve food was Persians. They invented Yakhchal, a type of an ice pit.”  The history of refrigeration is a very interesting subject with vast effects from one end of the world to the other.

According to our studies done on behalf of your St Louis Refrigeration Sales, we learned that ice harvesting was the only method of food refrigeration for centuries.  In fact, in 18th century England, servants collected ice in the winter and were putting it into icehouses. “Icehouses were places where the sheets of ice were packed in salt, wrapped in flannel, and stored underground to keep them frozen until summer. In the 19th century, the first ice boxes started appearing in England. At that time, the first commercial ice started appearing with spreading of ice-storehouses and iceboxes. Frederic Tudor started harvesting ice in New England and shipping it to the Caribbean islands and to the southern states. At first he had ice wastage of 66% but with better insulated ships he reduced the waste to 8%. He expanded ice market and by the early 1830s ice became a mass-market commodity.”

We hope you have enjoyed this lesson on the history of refrigeration brought to you by your St Louis Refrigeration sales and repair near Sunset Hills.

 

The History of Refrigeration

The History of Refrigeration

historyToday, on behalf of your St Louis Refrigeration sales and install near Maryland Heights, we have decided to explore the history of the subject at hand.  First, we ought to define it as much as we can from the start.  In its most basic form, refrigeration is a method in which work is done to remove heat from one location to another. Refrigerators, then, are machines, sometimes household appliances, sometimes commercial, which are used for such a purpose and are generally used to keep food fresh longer. Although they are a relatively modern invention, people have been attempting to extend the life of food via freshness by keeping it at lower temperatures for thousands of years.

“History of refrigeration is long and refrigeration changed along the way from the pretty primitive yet ingenious to modern technology which allowed people to have refrigerators in their house and not depend on nature.”   Some of the basic, yet pertinent facts to cover on behalf of your refrigeration sales and service in St Louis are as follows, “…may look like mundane machines that everyone has in their home and that work on simple physical laws that work since the beginning of time but that is not all that can be said about them.”

The invention of the refrigerator is a good place to land and wrap up for now, only to pursue the topic of refrigeration history in the next post as well, in more details.  “One showed how with simple apparatus temperature can be lowered artificially; the other held the first patent for a refrigerator. Both are part of the history of artificial refrigeration and without them who knows how the world would look.”  For a more complete discussion about refrigeration and its history, please feel free to look up and read our next post on behalf of your St Louis Refrigeration Install near Maryland Heights MO.
