My SD800IS was working fine while in the very hot/humid environment of Yap. I took it out of my air conditioned room and went to take a picture almost immediately. The view finder, the LCD image and the lens were all fogged. The camera worked but took foggy images. Eventually the fog cleared and my photos were fine but most of the controls no longer work. I can change the selector knob that determines if the camera is on auto, manual, video or display modes but it won't zoom and the program and menu modes no longer work. When the camera is turned on it shows a digital time display until the shutter button is pressed. Then it shows the subject and is ready to take a picture. Have I given you enough info to determine what is damaged?

Portable air conditioning offers you the convenience of mobility. All you have to do is roll the portable air conditioner to the room in which it's needed. Install an exhaust hose out a window or other opening (everything you need is provided) and turn it on. The installation process for these units is very simple. These portable air conditioning units are built small enough to be very mobile and are supplied with wheels for easy movement. A portable air conditioner will also work very well in apartment situations where you will often find a window unit is unacceptable.

Portable air conditioners are very unique in that they are portable and can be easily moved to different locations in your home or business. They can be a highly effective way to either help out an existing HVAC system in one room or cool a single room entirely. They are also one of the best ways to cool a room or area without having to install a window mounted unit.

These air conditioners use a compressor and Freon to cool just like normal air conditioning. They are very effective in cooling rooms and to keep the humidity low. Like normal air conditioners portable units extract hot air that must be vented. That is why they need to have the exhaust hose to the outside. These units can cool air as well as air conditioning done with window air conditioners. However they do not require installation like conventional window air conditioners this makes them very convenient for seniors or physically challenged people. Most portable air conditioners are supplied with a window kit. This kit contains exhaust hoses that will work in any window: double-hung, casement, awning or slider. Because they vent through an opening like a window they require no permanent mounting like window air conditioning.

Portable air conditioners are a very good cooling option for those who can't use the more conventional air conditioning methods. Remember though that this type of unit is not as efficient as most window units or conventional air. So while they may make your environment cooler, it won’t turn your tent into a room at the local hotel.

So as you can see these air conditioning units have some great advantages over other types of air conditioning. They are a great alternative for unique applications where central air or conventional window units are either unfeasible or too expensive. During special events, portable air conditioning can also be a great way to keep guests or equipment cool and comfortable. Always be aware though that because portable air conditioning will remove moisture from the air, they will also need to be drained occasionally similar to a dehumidifier.

Does your application warrant a permanent air conditioner of some form or should you just use a portable one? There are some interesting things to consider when making that choice. Weigh out all of the different options and make that decision based on what will best suit your needs.
