The invention relates to a method and an arrangement for increasing the Heizenergiepotentialnutzung in the air conditioning of greenhouses, which is characterized by a modified Luftfuehrung. Climatically treated air is fed directly to the plant population and only comes into contact with the greenhouse enclosure surfaces after it has left the stock. From there, the return / extraction of air takes place. With the method, a better influence on the state of the near-by indoor air (humidity, temperature, movement) is achieved, the energy demand of the greenhouse at a constant temperature level in the stock due to the reduction in air temperature in the area of the Gewächshausausfassung lowered and the use of relatively low-temperature heating energy or smaller heat exchanger by the achieved increase in the heating energy potential allows. {Gewaechshaus; air conditioning; Inventory temperature; Humidity; Air temperature; Air movement}
