It is not uncommon for corporate or medical facility server rooms to grow increasingly dense as the need for data storage and transfer grows with a business. The end result can be a server room that starts to run hotter than the company would like. This is especially true when the server room is built into a leased space that was never designed for the types of heat loads that a room full of servers will create. One solution that is seeing more application is to add a Koldwave air-cooled portable air conditioner to the room. In this case the Koldwave unit was added to the end of the rack cold aisle in a semi-permanent installation. The result was a relatively low cost answer to the overheating that was also easy to install.
