To meet increasingly rigorous mechanical codes and standards, today’s ventilation systems must become more sophisticated. Sensible-cooling loads are being reduced as codes require tighter, more energy-efficient building construction, higher-efficiency HVAC equipment, and more precise ventilation. Consequently, latent loads are becoming more significant in overall HVAC load calculations, and, in many instances, design-load sensible-heat ratio (SHR) is below 0.60.
Applying DOAS With Heat Pipes
Combining heat pipes and dedicated outside air creates reliable, energy-efficient, low-maintenance systems.
