Climate Change and Air Conditioning

As temperatures go up, so does society’s need to keep cool by using air conditioning. The more society uses air conditioning, the global climate will change. Global climate changes effect how much energy the world uses. More and more people across the globe are staying cool by using air conditioning. Scientists around the world are becoming more and more alarmed about the effect of the gases these air conditioners omit on the environment. These powerful chemicals are a component of the agents causing global warming.

A treaty named the Montreal Protocol, which is approximately 25 years old, was created to mandate the control of harmful gasses such as CTF coolants. CFC coolants cause enormous damage to the ozone layer. The treaty was created in the hopes of protecting the ozone layer by stopping these coolants from being used by the general public. The CFC coolants that are exceedingly damaging to the ozone layer have been predominantly eliminated from use.

However, scientists warn that while theses new gases, known as HCFCs, are contributing to global warming thousands of times more than carbon dioxide. HCFC’s are not as damaging to the ozone layer as previous gases used were, but they are being used in record amounts. In the developing world their use has more than doubled in the past two decades alone. These rising level of use have scientists concerned.

The HCFC coolant called 410a is labeled “environmentally friendly” because it does not damage the o-zone layer. The warming effect it has though over 2,000 times that of carbon dioxide. Because of its environmentally friendly reputation, industrialized countries began switching to it over a decade ago. The Montreal Protocol treaty does not control the rise of these coolants because it only regulates any ozone depleting gases.

As a matter of fact, leading scientists in the field have considered that if all appliances that are entering the world market today use the newest gases currently employed in air-conditioners, up to 27 percent of all global warming issues will be attributable to those gases by 2050. On average, air conditioning emits more greenhouse gasses while it is pushing the heat out of a house or building than a furnace uses putting that same heat into a house or building.

In particularly hot countries, such as India and China, sales of air conditioning units grow by a vast 20% each year. This rise in sales is attributed to a fast growing middle class. And in spite of the United States’ goal to eliminate the use of HCFCs, China and India are continuing to use them. The possible demands for air conditioning of Mumbai and India alone are expected to be about a forth of those of the United States. At this time, the technology to create a commercial alternative to air conditioners that is completely environmentally friendly just does not exist.
The changing climate will undoubtedly lead to more hot days and more hot days and heat waves. Consequently, people will continue to use additional energy and air conditioning to stay cool. As this happens, it is very likely that blackouts and electricity shortages will increase. Meaning the cure to one global environment problem is only causing another.

In what many would call ironic, the act of cooling off by air conditioning only seems to be making our planet even warmer. Which leads to a vicious cycle of turning the air conditioning on to cool off and in actuality the air conditioning is simply making the planet even hotter. Most electricity is produced currently by burning fossil fuels; using more electricity to run air conditioners will also add more greenhouse gases to the atmosphere.

At this time northern California is using hydro-power to produce electricity. However, with climate changes come shifting precipitation patterns. Irregular precipitation patterns could mean that some areas will no longer have the water necessary to make hydro-power. As climate change causes precipitation patterns to shift some areas that currently have plenty of water to make hydro-power, such as northern California, might not have enough water in the future. If enough electricity can not be produced, these areas could experience power shortages and blackouts.

What can we do about climate change?

  • Keep air conditioner efficiency in mind.
  • Plant tree around your home and office that provide shade, cooling naturally.
  • Use fans more often’ ceiling fans are great.
  • Save energy by turning the thermostat down a few degrees.
  • Choose energy efficient appliances.

Schools Without Air Conditioning

Air conditioning in schools, or rather the lack thereof, is a legitimate concern for parents and teachers. With temperatures rising all over the country, there are many schools that are now dealing with incredibly hot temperatures, and no air conditioning to combat the heat. This can be a dangerous combination for students and teachers.

In Florida, schools are provided with air conditioning to deal with the oppressive heat and humidity. This is not the case for schools around Chicago and in other parts of the country where the heat can become intense. To prevent overheating of the buildings and people, schools should provide air conditioning. There are a few different options, and some can be quite cost effective for struggling schools.

Central Air Conditioning

Central air conditioning is the most preferable choice for cooling large buildings and structures. It vents air into each room via air ducts above the ceiling, creating a uniform temperature for whichever rooms are connected to the same air conditioning unit. Air conditioning removes humidity from the air, making it an excellent choice for schools in humid areas. There are little tips and tricks for keeping air conditioning costs low, and schools can employ these tips to be able to provide air conditioning for students and employees. Turning the air conditioning up, or off, at the end of the day is a good way to save money. Keeping the outside unit, which contains the compressor and condenser, in a shady place, and doing as much as possible to keep sunlight from entering the building are other ways to lower cooling costs of the school. Choosing a SEER rating of 13 or higher will keep the unit energy efficient, and save money over the long run. Central air conditioning is, however, quite pricey to install. If schools are unable to provide central air conditioning, there are other options.

Window Units

Window air conditioning units are fairly inexpensive, and easy to install. Schools that make use of trailers for classrooms may especially benefit from window units. They can be placed in an open window, and keep the room cool. The sealing around the window is not tight, and may cause air leaks. However, a window unit is still more energy efficient and cost effective than using a portable air conditioner.

Wall Units

Wall air conditioning units are very similar in price to window units. If central air conditioning is not an option for air conditioning in schools, wall units can be a great choice. Wall units are commonly used in hotels. Installation can take several days since the unit is mounted on the wall. The wall may need braces to ensure safety of the wall and unit, not to mention safety of students and teachers. Wall units are energy efficient, and can be cost effective cooling small spaces, like a single classroom.

Swamp Coolers

Evaporative air coolers, or swamp coolers, are the perfect option for air conditioning in schools in dry, desert-like climates. Swamp coolers would not work for schools in humid areas, since humidity can be quite dangerous, and swamp coolers actually add to the humidity. However, if a school in Arizona or New Mexico is looking for air conditioning, swamp coolers are perfect for the classroom. They are low cost, low maintenance, eco friendly, and easy to use. They do need to be refilled every 6-8 hours, as evaporative air cooling uses water to cool the air.

Portable Air Conditioning

Out of all the options for cooling a building, portable air conditioning is the least preferable. Although easy to install and use, it is high priced and not as cost effective as other options, like the window or wall air conditioning units. It can raise electric bills by quite a bit, making them a poor option for installing air conditioning in schools.

With summer heat that can drag on for the at least the first several months of school, not to mention how early in spring it can begin to get hot, schools should be concerned with how to put air conditioning in schools for the safety of the students and employees. Central air conditioning is the easiest and best choice, although the most expensive. Window or wall air conditioning units are perfect for cooling a room, rather than an entire building. Swamp coolers work well for desert-like climates, and portable air conditioning is not a cost effective option for schools.

Getting the Very Best Air Conditioning

There are a variety of options available for cooling your home. There are portable air conditioners, window and wall units, swamp coolers, and central air conditioning. With all these options, how do you know which one is best for you? There are a few things to take into consideration before determining which 1 hour air conditioning is best for you. You will need to take into account the climate in which you live, what fahrenheit temperature you would like the keep your home at, and what will be easiest for you.

Portable Air Conditioners

While portable air conditioners are easy to use, they are on the more expensive end of 1 hour air conditioning. Portable air conditioners are compact and easily transported from room to room. They are not really energy efficient, therefore they can raise your electric bill. Overall, portable air conditioners are really only your best option if all the others are out. Ease of use and portability are cancelled out by high costs and having to roll the air conditioner to each room and wait for it to cool down.

Window and Wall Units

Window and wall units are great for cooling a room. They are not transportable, but they are more energy efficient. Window units, however, take up window space and can “leak air” due to lack of proper sealing around the edges. They are easy and quick to install, and are cheaper than portable or central air conditioning. Wall units do not take up window space and are sealed well along the edges making them more efficient at keeping a steady fahrenheit temperature. They can take several days to install, however, as the wall often needs to be braced to hold the weight of the air conditioning unit. If your building is unable to install central air conditioning, window and wall units are really great options for cooling your home.

Swamp Coolers

Evaporative air coolers, or swamp coolers, are eco friendly, low cost, low maintenance, and a perfect option for people who reside in a dry, hot climate. Swamp coolers sounds like a wonderful option, but if you’re living in Florida, the last thing you want to do is make your home more humid. Swamp coolers cool the air with water, creating humidity. They also need to be refilled with water every 6-8 hours. They are simple to use, easily transported, and the perfect choice for residents of Arizona or New Mexico. If you’re in Florida, your best option is coming up.

Central Air Conditioning

Living in Florida, central air conditioning is your best option. 1 hour air conditioning can come with a hefty price tag and take several days to install, but it is completely worth it for beating the heat. Central air conditioning is becoming more energy efficient all the time, and can be a good investment to keep mold and allergens out of your home. Most new buildings are built with central air conditioning, to keep a comfortable fahrenheit temperature of around 78 degrees in buildings. With central air conditioning, air is vented throughout the house by being moved through air ducts above the ceiling. These air ducts should be kept clear and clean, not allowing dust and allergens to transfer throughout the house. Central air conditioning is easy to use, controlled by a small box mounted on the wall. From there, you can control the temperature, see the level of humidity in your home, and even program times for the air to go off or raise, and come back on to cool down the house. It is imperative to keep the air conditioning unit in good working order and have it regularly maintenanced. Keep weeds and tall grasses away from the outside unit, and with regularly maintenance visits, your central air conditioning will keep you happy and cool in the Florida heat.

Before buying an air conditioning unit, take into consideration your climate and needs. Central air conditioning removes humidity from your home, while swamp coolers add it. Window and wall units are inexpensive, but do not thoroughly cool more than one room. Portable air conditioners are expensive and do not cool as efficiently as other options. 1 hour air conditioning is important in the Florida heat, so choose the option that works best to keep you from overheating.

Make Your AC More Efficient

The air conditioning parts on your unit allow your air conditioning to run smoothly and efficiently. If one part breaks down, or is damaged in some way, your air conditioning ceases to run with productivity. Learn how to maintain your air conditioning parts to make your unit run more efficiently, increasing productivity.

Air Conditioning Parts

The major air conditioning parts of your unit are the compressor, condenser, evaporator, and fan. The compressor and condenser are usually located outside of your home, while the evaporator and fan are inside. All of these must be kept in good working order to keep your air conditioning running efficiently. Concerns to watch out for are leaking and debris. Always check your outside unit for leaking of any kind. If Freon is leaking, it will appear as a strange green substance. Freon is the substance that allows your air conditioning to blow cool air, so if there is a leak, you will need a certified technician to check out the problem and repair it. Freon does not normally need to refilled, so if Freon is low, that is also a sign that there is a leak. Any water pooling anywhere on the unit is a sign that you need to call your air conditioning repair company. Clear away any weeds and debris from around your outdoor air conditioning unit. Tall grasses, weeds, and debris, can block drains and equipment, causing your air conditioning to break down, or decrease productivity. On the inside of your home, pay attention to how well your air conditioning is working. Do you find some rooms are warmer than others? Is your air conditioning blowing hot air, rather than cool air? These are signs that you should have a technician check out your air conditioning parts to make sure that they are running efficiently. Air conditioning parts can be complex and intricate for those who are unfamiliar with air conditioning units, so having a certified technician evaluate and fix the problem is a guaranteed safety net that your air conditioning will be back to cooling your home efficiently in no time.

Other Ways to Increase Productivity

Your air conditioning’s job is to cool your home, efficiently and quietly, without causing you grief. While the major air conditioning parts are usually your main concern when considering how to keep your air conditioning running efficiently, there are other things to consider. Air ducts are what moves central air conditioning throughout your home to cool it. On occasion, air ducts can become dirty, so you might want to have them cleaned. This is the sort of job that isn’t needed regularly, but on an as needed basis. Any visible debris is a sure sign that they should be cleaned. Infestation by vermin is another. Sometimes, you just need to have your air ducts checked because you can’t always see the problem. Mold can grow, and dust can collect, in your air ducts, and then be transferred around your house when the air conditioning is running. Mold and dust can be harmful to your health, and can provoke allergies. Another way to ensure that your air conditioning is running efficiently, is to set your thermostat. Most central air conditioning units are equipped with a handy little box that is mounted on your wall and allows you to control your air conditioning settings. You can preprogram the air conditioning to turn off while you are out of the house for work, and turn on in enough time to cool down the house before your return. You can also view the level of humidity in your home to make sure that the air conditioning unit is doing it’s job of removing humidity from the air inside. Keeping an eye on the extra parts of your air conditioning can keep it running efficiently.,

If you are at all concerned about parts of your air conditioning, and whether they are working properly, contact your trusted air conditioning repair company. They can send a certified technician to check your air conditioning parts and the productivity of your unit and give you peace of mind. In the Florida heat, you don’t want to be concerned about your air conditioning not running efficiently.
