New and Underutilized Technology: Evaporative Pre-Cooling Systems
The following information outlines key deployment considerations for evaporated pre-cooling systems within the Federal sector. This information spans:
- Climate and Regional Considerations
- Key Factors for Deployment
- Ranking Criteria
Evaporative pre-cooling systems install ahead of the condenser to lower the condenser pressure. These systems can also work with an economizer. Evaporative pre-cooling reduces the requirement for energy intensive DX cooling.
Evaporative pre-cooling systems are applicable in most building categories.
Climate and Regional Considerations
Evaporative pre-cooling systems are well suited in dry climates.
Key Factors for Deployment
Water usage needs to be taken into account in evaporative pre-cooling system deployment. Several variations of this concept are available.
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.
