Case Study: Heat Recovery and Demand Controlled Ventilation in Industrial Kitchens

Industrial kitchens have high HVAC load requirements due to high exhaust rates from hoods. Especially in cold climates to heat the makeup air in winter requires high initial and - more importantly - high operating costs. Heat recovery always looks like an attractive alternative due to the high temperatures of hood exhaust air. However, since hood exhaust is quite dirty, heat recovery sections are clogged very fast. Heat recovery systems are established in six restaurants in Ankara, Turkey.
