What do economizers achieve with the same power input?

Economizers are designed to optimize energy usage in HVAC systems by utilizing outside air to cool the building when conditions are favorable. The principal function of an economizer is to reduce the reliance on mechanical refrigeration, which can significantly enhance the cooling system's overall efficiency.

With the same power input, economizers achieve increased capacity because they allow the system to take advantage of cooler outside air instead of solely relying on the energy-intensive process of chilling air through mechanical means. This capability enables the system to provide a greater cooling effect without requiring additional energy beyond what is already being used. The integration of economizers leads to the potential for a lower overall energy demand while still meeting or exceeding the cooling loads needed for the building.

In summary, economizers facilitate more effective cooling processes at existing power levels, demonstrating increased capacity while also contributing to energy efficiency improvements.
