The results above provide you the cost savings that can be achieved by combining CPI Passive Cooling® System with three of today’s most effective cooling solutions. These are:
KyotoCooling® – KyotoCooling utilizes outside air temperatures as the cooling source for the data center during hours when the outside dry-bulb temperature is less than the data center supply air temperature requirement. Using a rotary heat wheel (energy recovery system); KyotoCooling removes heat from inside the data center with minimal air transfer between the ambient and computer room temperature. KyotoCooling provides all of the benefits of evaporative air-side economizers without the exposures like contamination and humidity control. CPI Passive Cooling Solutions maintain the critical hot and cold air separation required for maximum KyotoCooling effectiveness.
Water-side Economizer – A water-side economizer uses the building’s cooling towers to cool the data center chilled water loop by taking advantage of the hours of the year when the outdoor dry-bulb temperature is sufficiently lower than the chilled water supply set point. Instead of running the chiller plant during those hours, the cooling tower water is bypassed around the chiller plant and diverted to a heat exchanger so that it can cool the chilled water directly. CPI Passive Cooling Solutions increase economizer hours by providing complete isolation between supply and return air in the data center, allowing for higher supply air temperatures and associated higher chilled water temperatures.
Evaporative Air-side Economizer – Instead of cooling and re-circulating the hot air from the servers, evaporative air-side economizers expel the hot air outdoors and draw in outside air to cool the IT equipment when the outdoor wet-bulb temperature is below the data center supply air temperature and employs adiabatic pre-cooling during those hours when the ambient temperature exceeds the data center requirements. This portion of the evaporative air-side economizer control scheme is called free cooling. Evaporative air-side economizers can reduce HVAC energy costs in cold and temperate climates and warm and dry while also potentially improving indoor air quality, but are most often not appropriate in hot and humid climates. CPI Passive Cooling Solutions maintain the hot and cold air separation required for maximum evaporative air-side economizer effectiveness.
