Most server rooms do not have easy window access and may be interior rooms, which makes venting a complication. As a solution, you can direct the hot air discharge hose into a drop ceiling space or through a hole in the wall to an adjacent room. Our is a great choice for server rooms because it is a ceiling-mounted portable air conditioner. It can be easily mounted above a standard drop-ceiling, as shown below.
Portable air conditioners are often used for supplemental cooling in computer server rooms or as the primary cooling source in these rooms on weekends, when central air conditioning may be shut off. We recommend portable ACs that use fully self-evaporative technology for these applications. This means that you will never have to manually remove collected condensation and can leave the portable AC running unattended.
Some portable air conditioners have one hot air exhaust hose, and some have two air hoses: one for air intake and one for hot air exhaust. A single-hose portable air conditioner will take air from the room it's in, cool it, and return most of that air back into the room. During this process, a small amount of that air will be used to cool the unit and will be subsequently blown out of the air conditioner's exhaust hose. This creates slightly negative pressure within the room being cooled, as a small amount of air is constantly being removed from the room. If this negative pressure is anticipated by drawing unconditioned air into the room from adjacent spaces, then the cooling efficiency is slightly affected.
A dual-hose portable air conditioner works by taking in air from the outside through one hose and using that air to cool the unit. The hot exhaust air is then expelled through the second hose. This process does not create negative pressure inside the room being cooled. However, there is a tradeoff. Dual-hose units use warmer, unconditioned air to cool their compressors, which results in slightly less efficiency. They also employ two internal fans, which can mean slightly higher energy usage. At this time, we have not seen conclusive evidence that either solution, single- vs. dual-hose, is better than the other when all factors are considered.
For sliding glass door installations, we recommend using at least two window installation kits that are designed to work with your particular portable AC to completely cover the door opening. The two window installation kits can then be secured together using screws. Plywood and Styrofoam can also be used as covering and insulation material when installing a portable air conditioner into your door frame.
Venting portable air conditioners through sliding glass doors is much more complex than simple window installations. The window installation kits used for traditional windows typically don’t extend far enough to cover the height of the door.
