The dog days of summer have passed by again, and, although I welcome the changing leaves and cooler nights, it is bittersweet after a summer with so many gorgeous days. I live in the South, where we truly believe that we have the best of both worlds, weather-wise. True, we can have some pretty warm summers and an occasional hard winter; but, for the most part, we make the best of it all. As it comes to a close, I will miss those temperate days hiking in Appalachia, and basking at the coast. And on the really hot days, just spending the day at home and letting the sun in.
Like most people, I have air conditioning, so I can simply “hang out,” and wait for a nice day to come along. And boy, did we have a lot of them this year. It is hard to imagine that, not a century ago, I would have felt completely different about this temperate area that I live in. Before the advent of Heating Air Conditioning, many of the people who inhabited this capital city would go running for the hills, or rather, for the north, to escape the sweltering heat. No doubt I would be with them. As much as I love the outdoors, I can not deny that the cool indoor retreat from them, into air conditioned space, makes this possible.
The truth is, if Air Conditioning hadn’t been invented, I never would have lived here. My parents were transplants from up north, which came down as this area expanded, to work for one of the large tech corporations. Before they each retired, they worked each day in large, Air Conditioned offices. The products they were building required climate controlled manufacturing processes in order to exist, and we went to the market once a week for food and then basically forgot about it, moving on to other things.
However, I can’t imagine life any other way, and can’t imagine missing all of the lovely seasons that I have watched come and pass in this area of the country. Air conditioning is probably one of the most taken for granted luxuries that we have. It makes nearly everything we do more enjoyable, if not possible. For the most part, air conditioning goes unnoticed. When it does come to our attention, the results are controversial, if not emotional! When our loyal Heating Air Conditioning goes out, it becomes one of the top priorities in our life –it must be fixed, and soon! Disagreements about the settings of a central air or Heating Air Conditioning thermostat settings or can wreak havoc upon otherwise civil roommate or spousal relationships.
Furthermore, there are political and social ramifications to our dependence on such luxuries. If Air Conditioning is necessary, how can we be more responsible in the ways we utilize it? Such concerns have lead to the development of increasingly efficient Air Conditioning solutions, such as Heating Air Conditioning. Whether you love it, or hate it, refrigeration and Air Conditioning are truly one of the most life altering inventions of this century.
HISTORY IN AMERICA
Just think about it…the Air Conditioning technology we use on a daily basis, which shapes our lives into what they are today, did not come around until the 1920’s. Prior to refrigeration, we would have to visit the market and the butcher each day in order to eat fresh food. Whatever we purchased would need to be eaten right away. Unless, by chance, we were wealthy aristocrats, lucky enough to have ice delivered regularly to their ice box. In this case, we could potentially] store food for 2-3 days. The same technology that was used for the first refrigerators gave rise to modern Air Conditioners and Heating and Air Conditioning. So, no refrigeration, no Air Conditioning.
Without the convenience of central air or Heating - Air Conditioning, he summer months in many of our largest and fastest growing cities today would turn into stagnant, intolerable places. Many of the residents would retreat, leaving them as empty as ghost towns, as everyone headed north to avoid the sweltering heat and humidity. Forget about doing anything productive during this time; those of us who wished to stay would likely feel contained to our porches, fanning ourselves for dear life, dreaming of the Heating & Air Conditioning of the future. But all of that was destined to change by the turn of the century. Inventors, students, and mechanics alike were beginning to see the potential for a refrigerant system that was practical, at least on a large scale for industrial purposes. The ancestors of modern day air conditioner, heaters, and Heating and Air Conditioning were about make their big debut.
So, how did the comfort we have come to expect and enjoy in our homes come about? Well, much credit should be given to Willis Haviland Carrier. Willis Carrier graduated from Cornell University in 1902, and set out to develop heating and cooling technologies. One of his major contributions was, in 1924, the development of Dew Point Control. This humidity and temperature control device had the cooling capacity of 108,000 pounds of ice per day.
At this point in history, the idea of Air Conditioning ourselves down was still merely in its primordial state; the technologies were primarily being created for, and utilized by, large industry. Printing shops got the first taste, as the technology allowed them to control the climate enough as not to have shifts in paper size, caused by humidity. Day’s worth of prints would not be destroyed by too much humidity on a particular day.
Other manufacturing avenues came on board shortly thereafter, realizing that they could now control factors which affected production and quality. This allowed for the manufacture of things otherwise impossible (ultimately, many computer and electronic components), and specific applications within manufacturing could be optimized by controlling the ambient temperature and humidity. “Comfort cooling,” the idea which gave rise to modern day air conditioning as we know it (beginning with room coolers much like a single zone Heating - Air Conditioning), was not far behind the industrial discovery of temperature and humidity control.
Around the same time as Carrier’s first air conditioning invention, Alfred Wolff, a consulting engineer, had already begun designing comfort cooling machines. Wolff’s air conditioners eventually made their way into the New York Stock Exchange, the Hanover National Bank, and the New York Metropolitan museum of art. By 1917, many movie-goers around the country could be lured in with promises of a theater that was “20 degrees cooler than the outdoors”. So the idea of air conditioning implemented to improve our quality of life, not just our production capacity, was beginning to travel, and fast. Willis Carrier, along with other partners, formed the Carrier Engineering Company in 1915.
The company formed out of the encouragement of all of the potential applications of developing climate control technology. One major development of Carrier (which is implemented in much of the Air Conditioning that we know today) was the development of a centrifugal compressor, which replaced the old piston-driven compressor. The compact size and exceptional efficiency of Heating & Air Conditioning would not be possible without this breakthrough. The Carrier centrifugal compressor Air Conditioning model began making appearances in 1924, with its first installation at the J.L. Hudson Department store in Detroit, Michigan. Office buildings would soon follow, and the introduction of domestic Heating and Air in American homes was on the horizon. At this point, many of the players in the Air Conditioning game could probably envision the Heating and Air Conditioning, albeit without the specifics worked out. But they knew it was possible to create an Air Conditioning appliance which was compact and practical, yet powerful enough to produce large scale and offer everyone a higher standard of living for everyone. By the early 1920’s, many had joined forces to compete for the growing demand of refrigeration technology, and so the race was on to develop an Air Conditioning System for residential home use.
Even the automotive industry was interested in playing a role. William Durant, then president of General Motors, purchased the Guardian Refrigerator Company, which was renamed “Frigidaire.” By 1929, Frigidaire had produced a room cooler which was available to the public. (Frigidaire still remains on of the most competitive air conditioning manufacturers on the market, carrying Heating - Air Conditioning of all types, from single zone to large capacity, multi-zone Heating & Air Conditioning.) Along with other companies researching temperature and refrigeration technology (such as York, Kelvinator, and General Electric – all still key players in the Heating and Air Conditioning market) Frigidaire began the quest to create the fully air conditioned home.
Early attempts to provide the highest level of comfort in a practical and affordable way were met with many obstacles. Because Air Conditioners had historically been created primarily for industrial use, many of the models were extremely cumbersome and bulky. The 1928 Carrier “Weathermaker” was one of the first compact made-for-the-home machines; however, their business was still primarily in Air Conditioners for commercial use. It was difficult for Carrier’s Air Conditioning company to manufacture such units on a large scale, and they only produced a handful of them. (Imagine trying to meet today’s internet-based demand for home Air Conditioners and Heating - Air Conditioning!) Frigidaire, on the other hand, was well seasoned in the domestic market. Frigidaire was already equipping most modern American homes with refrigerators at a profitable pace. Furthermore, Frigidaire was responsible for eliminating another dilemma the refrigeration and Air Conditioning world was facing at this time: the problem of dangerous, toxic refrigerants which leaked and posed a significant hazard. This problem was resolved with the advent of Freon.
So, Frigidaire was the first company to produce, in large quantities, a commercially successful and mechanically practical “room cooler.” However, companies including Kelvinator, GE, and Carrier were not far behind. Each of these major companies immediately took on the development of the new, and newly safe, window-unit air conditioners. As it so happens, the very first home Air Conditioners were ductless, a trend that continues with our modern ductless window units, and resurfaces with the growing popularity of Heating & Air Conditioning.
The pervasive interest in air conditioning for the sake of human comfort continued to travel and expand. By 1939, the first automotive air conditioner was released. However, this was not the ultra-convenient and unobtrusive Air Conditioning that we are accustomed to simply flipping on and off today. In order to turn this automotive air condition unit off, the driver would actually be required to stop the vehicle, open the hood, and disconnect from the compressor within. Despite how ridiculous an idea this might seem today, the concept became very popular.
Having an Air Conditioner in your car meant that you were on the forefront of technology and style, and enjoyed luxuries in your life. (It is pretty funny, though, to picture such a “connoisseur” of the good life, popping his hood each time he exits his vehicle!) This just goes to show how much we really have always loved our Air Conditioning, everywhere we go, even if we do tend to take it for granted in present times. The concept of automobile refrigeration truly came to fruition in 1940, when Frederick McKinley Jones developed a roof-mounted refrigeration system. Frederick was a largely self-taught mechanic who utilized the concept of flash freezing to develop his refrigerant technology.
Frederick’s invention was far more efficient, effective, and practical than the automotive Air Conditioners which preceded him, and he turned out to be quite the refrigeration pioneer. Ultimately, he would attain over 40 patents related to refrigeration over his lifetime, in addition to patents he earned in other fields. This is a great example of how necessity facilitates novelty, and then, vice versa. This automobile cooling invention, inspired by the interest in practical “comfort cooling,” (and foreshadowing modern developments like the Air Conditioning and Heating) turned out to be an idea that was truly revolutionary, as it ultimately led to the food transport that shapes the American market for produce and other foods from coast to coast. Unlike many other cultural fixations of American society, which often wane or significantly change shape over time, the interest in comfort Air Conditioning has endured.
Throughout the remainder of the century, and beyond, Air Conditioning appliance manufacturers continued to develop and improve their products, offering more capacity at a more compact size. We arrive today at Air Conditioning solutions like the compact Air Conditioning - Heating; units that are whisper quiet and highly efficient in both Heating Air and Cooling Air, and seem that they need almost no further improvement. However, many of these companies continue a tradition of outdoing themselves in features or efficiency on a yearly basis. Although there were met with many pitfalls and failures, many of the design elements, and original principals, of the first Air Conditioners remain in the Air Conditioning & Heating units we purchase today.
The history of refrigeration and cooling is that of a beautiful marriage between necessity and novelty, as well as of human curiosity and invention. It was the curiosity of Carrier and others, which lead to breakthroughs in industry which ultimately shaped our society into what it has presently become. As we take our modern Air Conditioning for granted today, it is easy to assume that home Cooling and Heating Air was always in the grand scheme. This great invention (and our love for it) continues to drive an interest in the topic of refrigeration and Air Conditioning. But, in actuality, the life-changing result of having Air Conditioning and Heating for our comfort is perhaps an idea that we stumbled upon while working to solve other problems. In actuality, a very practical idea gave rise to something novel, which was assimilated into our daily lives, and now continues to allow for more productivity and creation, as we no longer have to spend seasons competing with the weather.
This exchange is rampant in the advent and development of Air Conditioning technology; from the birth of comfort Cooling and Heating Air out of an industrial application, back around to breakthroughs in home Air - Conditioning which find their way back to industries such as medical science, aerospace and electronics.
HOW DOES AIR CONDITIONING WORK?
If you are lucky, on a hot August day, your answer is “very well.” Or, many of us may provide a slightly more technical answer. “I turn on the Air - Conditioning - Heating, and it cools my house.” “Well, you set the thermostat to the temperature you would like, and it pumps cool (or warm) air out until the room reaches that temperature.”
That is a good, short answer to what your central air or Air - Conditioning - Heating compressor/condenser does. Regardless of whether you have ductwork, a Air - Conditioning - Heating, or a window unit, the purpose of modern day home Air Conditioning is to keep us in a comfortable climate, around the clock, 365 days a year. But how does it accomplish this? Air Conditioners, in fact, work the same way refrigerators do. The utilize much of the same technology, and the same components. Except, room and home Air Conditioners have a larger job; rather than cool just a small insulated space, they must cool an entire room , or, in some cases, an entire house. Whether you have central air or a Air - Conditioning - Heating system, the Air Conditioning aspect works the same way.
All forms of mechanical refrigeration require a closed system and a refrigerant. But what is a refrigerant? A refrigerant is a compound of elements which have a low boiling point. In other words, refrigerant chemicals will turn from liquid to gas very easily, without as much heat energy applied. (As opposed to, say, olive oil, a substance which has a very HIGH boiling point, rendering it useful for heated applications, such as cooking.) So, refrigerants readily return and stay in a gas state. Air conditioners utilize refrigerants that will most easily convert from gas to liquid, and back. Using this property of refrigerants, the air conditioning unit or Airconditioning - Heating can transfer heat from the inside air of home back to the outside. (And, this process can work in reverse when heating your home with a traditional or Airconditioning - Heating heat pump.)
An Air Conditioner has three main parts: the compressor, the condenser, and an evaporator. The compressor is responsible for compressing, or squeezing, the refrigerant, which will increase it energy and temperature. The condenser is responsible for condensing the resulting product of the compressor, and dissipates the heat. The evaporator is the portion of the Air Conditioning Unit that is responsible for removing heat from the internal air, and delivering the cool air into the space that needs it. (And, if your Air - Conditioning and Heating is equipped with a heat pump, it will work in the opposite fashion, by removing the cooler air and circulating the warm air that would be gathered externally. The compressor is usually the portion of the Air Conditioning Unit or, in the case of a Air - Conditioning & Heating, the “split”, which is located outside. It is the portion of the older central Air Conditioning Units which is associated with the most noise, but tends to be less of a nuisance in newer units and Air - Conditioning and Heating. The compressor is the first portion of the Air Conditioning Unit to receive the refrigerant after it has done the job of heat collection indoors.
These chemicals involved in air conditioning arrive at the compressor in the form of cool, low-pressure gas. The compressor’s work is exactly as it sounds; it compresses, or squeezes, the refrigerant compound, packing the molecules and charging it with energy. The harder the compressor compresses the gas it receives, the higher the energy and the more heat is created. As the molecules compress together, the gas is charged with energy and heat. Again, the harder the compressor works, the greater the heat of the fluid. The working fluid will then leave the compressor as hot, high pressure gas, and head for the condenser.
The condenser of the Air conditioning Unit or Air - Conditioning & Heating is also located outdoors. The condenser is equipped with metal “fins” which fan the heat created by the compressor away from the unit, and your home. Much like the radiator of your automobile, the condensers job is to dissipate heat as quickly as possibly as the machinery runs. During its time in contact with the condenser, the temperature of the working fluid lowers significantly, and will change from a gas back into a liquid. So, the condenser also has a fitting name, as it changed the hot gas created by the compressor back into cool liquid condensate. This can now be cycled through the system again, as the heat has successfully been removed. That is the function of Air Conditioning, whether it is central, “plug-in” or Air - Conditioning & Heating Units; to transport heat away from the place it is cooling, or into a place it is warming up. From the condenser, the liquid is on its way back to the evaporator.
The evaporator is located indoors, sometimes as a portion of the furnace, which is used to heat your house. (In the case of Air - Conditioning & Heating Units, the evaporator/handler refers to the indoor side of the “split”.) The cooled refrigerant liquid from the condenser enters the evaporator through a very narrow, tiny hole. As it crosses the hole, into the other side, the pressure on the refrigerant liquid immediately drops. This drop in pressure causes it to quickly evaporate into gas, as it has made contact with a new heat source: your interior. (Hence, the “evaporator.” Starting to make sense?) Since process of evaporation (transformation from liquid into gas) requires heat in order to occur, and the refrigerant is of the ilk that most loves to evaporate intgo gas, the compound will be utilizing any heat it can find in the ambient air to complete the transition back into a gas.
On a molecular level, heat is required to separate the molecules of the fluid into a gas. So, during this change from liquid back into gas, the refrigerant is extracting heat from the air around it. Like the condenser, the evaporator also has metal fins, which in its case assist the exchange of thermal energy with the surrounding air. The fluid then leaves the evaporator as a cool, low pressure gas. It has now completed the cycle and is destined for the compressor, where the process begins again.
So, there you have a somewhat simplistic explanation of how a modern day Air Conditioner or Air - Conditioning & Heating Units does its part of the work. The machine itself is designed to exploit the chemical properties of refrigerants in order to transport heat. But there is more needed than passive heat transport, in order to get the job done. How does this “conditioned” air get distributed throughout one room, or an entire house?
The internal evaporator component of most Air Conditioning Units and Air Conditioning & Heating System air handlers incorporates a fan, which re-circulates room air through the air handler. So, air from the room goes in, is blown across the fins of the evaporator’s fan. Heat is continuously removed from the entering air, and returned to the room, all ready to be enjoyed. Because warm air is lighter than cold air, the warmest air within an enclosed space is destined to rise to the ceiling. So, in locales which tend to have hot summers (most in need of cool Air Conditioning), structures tend to be built or equipped with vents that make good use of this phenomenon. Vents will be installed high on walls, or on the ceiling, in order to suck in the warmer air and redirect it into your appliance. In the case of Air Conditioning & Heating System, there are no ducts involved; the air handler itself is designed to manage the warm air, which is why the indoor portion of the “split” in a Air Conditioning & Heating System will often be mounted on a wall upper or ceiling. The heat from this air will then be used to cool the gas within the evaporator, or pumped back outdoors by your Air Conditioning & Heating System. As the heat is removed from the air, the air cools, and is then blown back into the house a lower level (often, vents in the floor, in ducted Air Conditioning Systems.)
The air in your home continuously cycles through this process until its condition reaches the settings you desire. An important accessory technology associated with modern Air Conditioners is the thermostat, which can often be set to whatever temperature and humidity level you prefer. The thermostat senses the temperature (and, in some cases, humidity) of the ambient air, and communicated with the compressor/condenser outdoors. When your desired settings are achieved, it will turn off the air conditioner (or, more often, lower to a whisper, “sleep” or “economy” mode) via an inverter. As the room warms up, the thermostat causes the compressor to ramp back up, returning to work, and the process of Air conditioning resumes. Heat pumps work similarly to a Cooling Air Conditioning System, except backwards. Rather than having the cold coil on the inside and the hot coils dissipating outdoors, it is the other way around. Heat pumps are an incredibly efficient means of heating your home, as it is simply transferring heat from the outside environment and, literally, “pumping” it back indoors.
Air Conditioning units and Heating System - Air Conditioning that are also equipped with a heat pump often have a valve which can switch the flow of the working fluid from one direction to the other. In the winter months, when this valve is switched, the liquid begins flowing in the opposite direction. So, unlike the cooling configuration, where the fluid makes its way from the compressor, to condenser, to evaporator, the process is reversed, collecting heat externally and then dissipating it from your air conditioning unit. One difficulty that arises with heat pumps is the external coils in freezing weather.
When the temperature is low enough, these coils may collect ice. If this occurs, the Air Conditioning Unit must melt this ice if it is to continue working properly. The obvious solution to this problem is to heat the outdoor coils, in order to melt the ice. In this way, the Air Conditioner actually a built-in ability to maintain itself; in cooling mode, these coils would be the hot coils! So, periodically, an Air Conditioner that is working hard as a Heat Pump may need to switch back into Air Conditioning mode in order to heat the coils of the compressor. But, it is cold outside! No one wants to crank up the air when they are trying to stay warm!
Modern air conditioner and Heating System - Air Conditioning manufacturers have come up with a solution to this problem. In order to avoid pumping cool air into the house, as this mode would cause the air conditioner to do in the summertime, most heat pumps are equipped with burners or electric strip heaters in order to warm up the cooled return air. After the ice on the external coil melts away, the heat pump will turn off these burners and resume heating in its normal mode. One of the key appeals of Heating System - Air Conditioning or “ Heating Units - Air Conditioning” Air Conditioning Systems is their simplicity.
With Heating Units - Air Conditioning, you can achieve excellent results in the area that you need, without having to settle for an ugly, leaky window unit, or retrofit your entire home with ductwork. With a Heating Units - Air Conditioning, you can be a quick installation away from the comfy environment you’ve been craving. However, there are a few things you should take into consideration if you have chosen a Heating Units - Air Conditioning. Heating Units - Air Conditioning can be quite an investment, but can provide years of hassle-free enjoyment if properly maintained.
The average lifespan of a Heating or - Air Conditioning is 12-15 years, provided you take a few easy steps to properly maintain your unit. Cleanliness is key if you would like your Heating or - Air Conditioning to provide you with the maximum years of comfort. In order to avoid breakdowns or freeze-ups, it is important to regularly change the filters of your Heating or - Air Conditioning air handler. Most modern units make this process quite simple, by providing easy access and lift tabs. Not only will this extend the life of your Heating or - Air Conditioning system, but it will also ensure that it is functioning at top form and efficiency. There will be no obstructions within the filters which will affect your air flow, and the air you receive will continue to be as clean and filtered as possible. It is also important to keep the outdoor compressor of your Heating or - Air Conditioning clean. Try to keep the area which surrounds your compressor clean of yard and other debris.
This will prevent obstruction of the compressor which can prevent optimal air flow. Even if you keep the area around the Air Conditioning or Heating compressor relatively tide, it may still need a little maintenance cleaning. Several times during seasons of heavy use, go outside and blast it down with a garden hose. Doing so will prevent overheating, which can cause a major break down of your Air Conditioning or Heating compressor. This can shorten the life of your system, and lead to costly repairs! When it comes to repairing your unit, in the case of an overheat or break down, make sure to repair it promptly. Never, never attempt any maintenance involving water, or repair until disconnecting the unit from the power source! And never attempt a repair yourself unless you have familiarized yourself with Air Conditioning or Heating mechanics and operation. Maintaining or repairing your Air Conditioning or Heating in the case of a malfunction, promptly, is important in order to avoid further damage to your Air Conditioning or Heating system. When in doubt, call a certified HVAC technician, to best protect your investment and extend the life of your Air Conditioning or Heating.
INSTALLING A MINI SPLIT
As a disclaimer, it is never a good idea to attempt any aspect of Air Conditioning / Heating installation unless you have a good understanding of the why’s and how’s of HVAC, and Air Conditioning / Heating in specific. However, here is a brief overview of how a Air Conditioning / Heating is installed. First, you will lay out whatever pad you plan on installing your Air Conditioning / Heating condenser on.
This is where your Air Conditioning / Heating condenser will be permanently installed, so be sure that you understand you configuration, and that the space does not exceed 50’, or the length of the lines you intend to use. You will want to also check and make sure it is level. Then, you can lay the condenser on the pad. Use a hole saw to drill a hole through an exterior line, large enough in diameter to allow the conduit tubing (containing the refrigerant and connection lines) through. It should also be in proximity to where you will be mounting the internal handler of your new Air Conditioning / Heating. Feed the conduit line, containing all of the connection components, through the hole you have drilled. Depending on the configuration, this may be up through a basement wall or from the exterior.
If you have already decided where the internal air handler is going to be mounted, you can screw in the metal mounting bracket into the wall at the manufacturer’s recommended height. Once this step in completed, you can also hang the indoor air handler of your Air Conditioning / Heating onto the wall. At this point, you should allow a qualified HVAC/electrical technician that knows about Air Conditioning / Heating to make the final connections, including the refrigerant line, PVC drain, and electrical wires. The technician will also be able to charge the line. At this point, you can install the Air Conditioners cover, any final details, and you are good to go with a new Air Conditioning / Heating that, if maintained properly, will last for years and years!
