The invention relates to the field of facility environment regulation and control, and discloses a positive-ventilation
greenhouse environment regulation
system, comprising an air-conditioning unit, blast tubes, a CO2 generator and an
ozone generator, wherein air inlets of the blast tubes are connected with the air-conditioning unit, the blast tubes each is provided with a plurality of air outlets, the air-conditioning unit is used for filtering air, heating or cooling, humidifying or dehumidifying air, and air meeting requirements on
greenhouse environment temperature and
humidity is delivered to different position in the
greenhouse in a positive-pressure state through the blast tubes. Besides, the CO2 generator is used for increasing concentration of CO2 in the greenhouse, and the ozonegenerator is used for generating
ozone for disinfecting the greenhouse. According to the embodiment of the invention, the positive-ventilation greenhouse environment regulation
system realizes comprehensive regulation and control on greenhouse environment in the positive-pressure greenhouse environment, delivers humid and cool air to the greenhouse space through the blast tubes uniformly, realizesquick
air change and needs low construction cost.
