Ventilation moves fresh air into and out of a space. It is essential for health and comfort. It removes moisture, odors, and pollutants. It brings in oxygen. It controls temperature and humidity. Ventilation is not the same as air conditioning. Air conditioning cools and dehumidifies. Ventilation exchanges air. In the kitchen, the ventilation is the range hood. It removes smoke, steam, and grease. It brings in fresh air. It is the ventilation of the kitchen. It is the ventilation of the cook.

Ventilation comes in several types. Natural ventilation uses wind and buoyancy to move air through windows, vents, and chimneys. Mechanical ventilation uses fans and ducts. A hybrid system uses both. A heat recovery ventilator exchanges heat between the outgoing and incoming air. In the kitchen, the range hood is mechanical ventilation. It uses a fan. It uses a duct. It exhausts to the outside. It is the ventilation of the kitchen. It is the ventilation of the same.
