Heating means (14) are provided in at least a number of air tubes, which heating means extend in the longitudinal direction of the air tube for heating air that flows past the heating means under the influence of the pressure means. A heating element (13) is disposed upstream of the heating means for heating air before it flows past the heating means. The invention further relates to an air circulation system for such a greenhouse and to a method for circulating air in a greenhouse.
