What is the purpose of the vent open or closed on a window air conditioner? An open vent on a window air conditioner allows fresh air from outside to come into the home and circulate along with the cool air produced by the unit. A closed vent prevents warm, fresh air from entering the home. What is a furnace fresh air intake vent? How can you use a portable air conditioner without an exhaust hose? While an open vent is not ideal for efficiency, since the unit has to work harder to cool down the warm air, it does serve a purpose. Leaving the vent open refreshes stale air and removes odors from the room. Additionally, the vent makes it possible to run the unit on the fan-only setting, which simply pulls in air from outdoors on cool or mild days. At least once a year a window air conditioner must receive routine maintenance, or else the unit's performance and efficiency may degrade while the risk of... Some portions of windows air conditioner units are simple to repair, but the compact design of window air conditioners might require users to disassemble a...

When deciding on a portable air conditioner, there are many important factors to consider. Some consumers may mistakenly purchase a portable AC that is inadequate for their cooling needs. Here are a few common mistakes to avoid when shopping for a portable air conditioner:Don't be confused by terms such as "portable air conditioner" and "air cooler," because these two appliances are quite different. While they both cool, they use completely different cooling methods to achieve lower ambient temperatures. Furthermore, portable air conditioners and air coolers (also known as "evaporative coolers" or "swamp coolers") have certain climate requirements. Portable air conditioners use refrigerants to reduce the temperature. During the cooling process, moisture is condensed out of the air and collected in a drain bucket or exhausted out through a drain hose or evaporated out the exhaust. Evaporative coolers use the simple process of evaporation to provide cooler air. A frame with a large fan is walled in by water-soaked pads, and this fan blows the warm outside air through the continually soaked pads to produce a cooling effect.

As a result, the air can be cooled by as much as 20 degrees.Climate Restrictions: These two types of portable coolers have climate restrictions. Because portable air conditioners act as dehumidifiers, they're best suited for areas with moderate humidity levels. On the other hand, swamp coolers add moisture to the air, so they are most effective in arid climates. Consequently, if the humidity level in your environment is above 20%, a swamp cooler will not work and a portable air conditioner will be more suitable. The correct way to determine a portable AC's cooling efficiency is to calculate the unit's BTUs and hope the air conditioner will provide cooling comfort in a variety of conditions. But this method can sometimes be inaccurate.  A portable air conditioner's BTUs is a good predictor of its cooling ability, but some other factors should be considered, such as the dimensions of the room and where the AC will be placed.BTU is an acronym for British Thermal Units and describes an air conditioner's cooling capacity. 

The higher the BTU, the stronger the air conditioner. However, the size of the room you're cooling is also important, and if you choose a portable AC with an incorrect number of BTUs, cooling efficiency will be compromised. A higher BTU rating than its corresponding room size will result in quick cycling and the inability to dehumidify the air. Also, if a portable AC has a lower BTU rating than is required for a particular room, there will not be adequate cooling. When choosing a portable AC and its BTU requirements, consider your room's dimensions and where it will be located. Shaded areas require a BTU reduction of 10%; sunny areas will require an increase in BTUs by 10%; and kitchens will need an addition 4,000 BTUs overall. EER stands for "Energy Efficiency Ratio" and measures how efficient a cooling system will operate when the outdoor temperature is at a certain level (usually at 95° F). This measurement is calculated as a ratio of BTUs to the amount of power the portable air conditioner consumes in watts.

The following is an example of how EER is calculated for an air conditioner with 12,000 BTUs and consuming 1500 watts: Here is an example of another portable AC with the same BTU rating but using 1200 watts of power.  This results in a higher EER:12,000 / 1200 = 10EER = 10The above calculations show that the second portable AC produces the same amount of cooling as the first but is more energy efficient. With that said, if you want to save money on your energy costs, choose an appropriately sized portable air conditioner with a high EER.Despite the fact that portable air conditioners require no permanent installation, they will need to be vented either through a window, drop ceiling, or wall due to the fact that they exhaust hot air from indoors and work as humidifiers. Therefore, this moisture must be vented out with the use of a venting kit that is provided with your air conditioning unit. When purchasing a portable air conditioner, keep your venting requirements in mind, and if venting through a window, be sure the window you intend to install the vent on matches the type of window covered by the kit (i.e., sliding or casement-type windows).
