This document discusses demand control kitchen ventilation (DCKV) systems, specifically Melink's Intelli-Hood system. The Intelli-Hood uses optic and temperature sensors along with self-learning algorithms to automatically adjust fan speed based on cooking activity levels. This leads to significant energy savings of 65% on average compared to standard kitchen exhaust fans that run at a constant high speed. The Intelli-Hood also improves ventilation, reduces noise, and ensures compliance with various industry standards and codes. Melink is a global provider of energy efficiency and renewable energy solutions, including their Intelli-Hood DCKV system, HVAC testing and balancing services, solar energy projects, and geothermal HVAC systems.
