  19. Energy Efficiency SHR close to 1 and Net Sensible Capacity are distinctive parameters of Leonardo Evolution in comparison with our competitors. Sensible Heat Ratio The primary objective of Precision Air Conditioning must be to dissipate the real heat load in the space. Any unwanted latent cooling (dehumidification) provides no useful service to the equipment being cooled and is a considerable waste of energy.
