DEVICE AND METHOD FOR AIR DRYING IN GREENHOUSE AND GREENHOUSE Russian patent published in 2010 - IPC A01G9/24 

FIELD: agriculture.

SUBSTANCE: system comprises water-distribution devices, by means of which water, which is colder than dew point of greenhouse air, is sprayed directly into air space of greenhouse. Parametres of devices are such that their use makes it possible to spray at least 50 litres of water per m² of greenhouse area per hour into air space of greenhouse. System additionally comprises water-collecting device to collect water sprayed into air space of greenhouse and to return it at least partially to specified devices of system. Method is characterised by the fact that air is cooled and dried directly in air space of greenhouse by supplying water, which is colder than dew point of greenhouse air by means of spraying or otherwise. Volume of water supplied per unit of time and temperature have such parametres that as supplied water passes through air space of greenhouse, more moisture is condensed in it from greenhouse air than amount of water, which is evaporated from it into greenhouse air. Volume of water supplied per unit of time sprayed into air space makes at least 50 litres of water per m² of greenhouse area per hour. Some water supplied to air space of greenhouse is returned for repeated circulation in air space of greenhouse. Greenhouse comprises water-distribution devices to supply water, which is colder than dew point of greenhouse air, into air space of greenhouse. Parametres of specified devices are arranged so that quantity of specified water used for cooling is more than 50 litres per m² of greenhouse area per hour. Greenhouse additionally comprises water-collecting devices, using which, at least one water, falling or passing through air space, is used repeatedly, and devices, using which, at least some reused water is again supplied into air space of greenhouse.

EFFECT: simplified process and reduced operational expenses to monitor moisture and temperature of air in greenhouse.
