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.
