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.”

Restaurant Equipment Investigation

Restaurant Equipment Investigation

refrigerationWhen it comes to our job writing for St Louis Restaurant Equipment sales and service, we find that the playing field is wide open.  There are many different facets to the industry and so many different pieces of equipment that are needed depending upon the restaurant type an details you choose for your business.  We will start today and continue the subject in future posts to follow, covering the main pieces of restaurant equipment you will likely need in order for your commercial restaurant to be successful.

“All commercial kitchens require a refrigeration unit of some type. Refrigerating food items prevents them from perishing quickly, preserves freshness, and provides cold food storage space.”  It is a sensible place to start in the realm of St Louis Restaurant Equipment installation near Sunset Hills MO.  Industrial grade refrigeration units are designed to meet the unique needs of the food industry, so they are a key purchase for any food handling operation, according to all things we found online. There are many varieties of coolers and freezers available, but your purchasing decisions will generally involve two types: reach-in or walk-in units and so this is a great place to begin when researching your restaurant equipment.

Before making a final decision, you will want to consider the size of your St Louis Restaurant near Sunset Hills and its specific equipment needs. “Although they have larger cold storage space and can be custom built to fit any kitchen, smaller restaurants may not require a walk-in cooler. There are even outdoor refrigeration and freezing options available if interior space is an issue.”  No matter which you choose, your refrigeration unit or units will be an essential part of your restaurant equipment needs indeed.  You will, therefore, also want someone professional when it comes time to put the units in your kitchen.  We recommend St Louis Restaurant Equipment Install and Repair near Sunset Hills.

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.

Many Facets of HVAC

Many Facets of HVAC

miscWhen it comes to the heating process that is involved within an HVAC system, and more specifically, the furnace of a St Louis heating system near Ladue MO, there are several key factors to consider and about which to learn.  “This heating process is accomplished using one of four possible heat sources — combustion (burning natural gas, oil, coal, or propane), electric resistance, heat pump, or solar energy collected on site.”

We will dive, now, further into the capillaries of each of these main points beginning with the heat exchanger, on behalf of your St Louis Heating Sales near Ladue MO.  “The heat exchanger is found inside your furnace unit’s housing. This component switches on when the furnace is activated by thermostat to produce warmer temperatures in winter. The heat exchanger pulls in cool air, heats it, and circulates the resulting heated air via your ducts and out through the vents.”

Next, we take a closer and more in-depth look at the evaporator coil which has an opposite role to the heat exchanger.  The evaporator coil, according to the experts from your Heating and Cooling repair and sales near Ladue in St Louis MO, acts to cool the air when your thermostat is set to lower temperatures in summertime. Working in a fashion that is somewhat familiar to an automobile’s radiator in order to produce cool air that can be circulated effectively through the ductwork, an evaporator coil is located in a metal enclosure on the furnace’s exterior, to the top or side.  Evaporators correspond directly to condensers both in the case of heating and cooling in St Louis and also in the area of refrigeration.  Stay tuned for more information from this source in future posts on the specifics surrounding the condenser and other facets of HVAC.
