		<description><![CDATA[HVAC Economizers (sometimes known as air-side Economizers) are useful for data centers which are located in regions of the world where the outdoor temperature is lower than the desired data center temperature (for at least some of the day or year) and the outdoor humidity is mild. Economizers save energy by cooling buildings with outside [...]]]></description>

		<description><![CDATA[This picture is from a BT Data Center in Holland, just outside Amsterdam. There are quite significant airflow benefits to keeping power and data cables overhead and out of the plenum space under the floor. Underfloor pressures can be maximized and airflow design can be maintained. If we can avoid lifting floor tiles when installing [...]]]></description>

		<description><![CDATA[  Dry coolers are used in many air cooled refrigeration systems. In case of low outdoor temperatures, outdoor air can be applied for cooling applications. In dry coolers, large fans create a forced airflow along air-to-water heat exchangers. Subsequently, the water circuit can be used for cooling of data centers, office buildings and industrial processes.  Dry coolers play an important [...]]]></description>
