Abstract

The invention relates to the field of facility environment regulation, and discloses a greenhouse environment regulation system based on positive pressure ventilation, including an air conditioning unit, an air supply pipe, a CO 2 generator and ozone generator. The air supply pipe is arranged in the greenhouse. The air inlet of the air supply pipe is connected to the air conditioning unit. The air supply pipe is provided with multiple air outlets. The air that meets the temperature and humidity requirements of the greenhouse environment is sent to various places in the greenhouse under positive pressure through the air supply pipe. CO 2 Generators for boosting CO in greenhouses 2 Concentration; Ozone generators are used to generate ozone for disinfection of greenhouses. The greenhouse environment regulation system based on positive pressure ventilation provided by the embodiment of the present invention realizes the comprehensive adjustment and control of the greenhouse environment in the positive pressure greenhouse environment, and can evenly transport wet and cold air to the greenhouse space through the air supply pipe, and the air replacement is fast and the construction cost is low. Low.

Description

technical field [0001] The invention relates to the field of facility environment regulation, in particular to a greenhouse environment regulation system based on positive pressure ventilation. Background technique [0002] High-efficiency, high-quality, clean, and safe production in greenhouses is the development direction of the protected horticulture industry, but unsuitable environmental conditions in the greenhouse have become a limiting factor for its development. In order to ensure suitable environmental conditions for crop production, improve the efficiency of greenhouse environmental control and the economic benefits of greenhouse production, it is necessary to comprehensively regulate the greenhouse environment, rather than simply regulate a certain environmental factor. The comprehensive control of the greenhouse environment involves heating, cooling, humidification, dehumidification, CO 2 The implementation process of replenishment, air filtration, disinfection,...
