New and Underutilized Technology: Multi-stage Indirect Evaporative Cooling
The following information outlines key deployment considerations for multi-stage evaporative cooling within the Federal sector. This information spans:
- Climate and Regional Considerations
- Key Factors for Deployment
- Ranking Criteria
Multi-stage indirect evaporative cooling is an advanced evaporative cooler that can lower air temperatures without adding moisture. These systems evaporate water in a secondary (or working) airstream, which is discharged in multiple stages. No water or humidity is added to the primary (or product) airstream in the process.
Multi-stage indirect evaporative cooling is applicable in office, research and development, service, and school applications.
Climate and Regional Considerations
Multi-stage indirect evaporative cooling is most effective in a dry climate, such as the western U.S.
Key Factors for Deployment
Multi-stage indirect evaporative cooling is well suited in applications where a high percentage of outside air is used or required.
Hybrid versions of multi-stage indirect evaporative coolers that also include a DX coil have been developed to meet a wider range of cooling requirements.
Federal energy savings, cost-effectiveness, and probability of success are ranked 0-5 with 0 representing the lowest ranking and 5 representing the highest ranking. The weighted score is ranked 0-100 with 0 representing the lowest ranking and 100 representing the highest ranking.
