If the air in restaurants is not properly ventilated, it can suddenly become ”visible” due to its strong odours; after all, the smell of food being prepared cannot go unnoticed.
Restaurant ventilation is directly related to kitchen ventilation. The problem that needs to be solved here is how to prevent the smell of food from the kitchen from spreading into the dining room, where customers enjoy their meals. This also presents an important part of the culinary experience, but it is often neglected. The energy surplus from the kitchen can be used during winter to heat other areas of the restaurant free of charge.
