Air-conditioner and humidifier for greenhouses - consists of air and/or water-suction pipe embedded in the ground, and ventilators pumps in the greenhouse

摘要

An air-suction shaft (4) is embedded in the ground to a depth (2)- for example thirty metres-sufficient to guarantee a constant temperature of over 9 deg.C in summer and winter. Connected to the suction-pipe (4) are heating or cooling pipes (3) which blow the sucked-up air via ventilator (5) into the greenhouse (9). A pipe (6) sucks up the greenhouse (9). A suction-pump and spray-pump (7) set at a pre-set air-humidity and temperature, sprays the ground-water into the greenhouse (9) via water-spray-jets (8). Controls (10), for example cylinders, controlled by temperature and air-humidity, open and close the openings in the greenhouse.
