Intelligent greenhouse and environmental control method using greenhouse effect heat collection and water-air film heat exchange

Abstract

The invention discloses an intelligent greenhouse and an environment control method utilizing greenhouse effect heat collection and water-air film heat exchange. The greenhouse is a multi-unit combination light-transmitting greenhouse with a high overhead structure, and an inner shed that is breathable and rain-proof is arranged in the middle, and the greenhouse is divided into an upper control buffer zone and a lower planting area. Sprinklers are installed on the top and the lower part of the insulation curtain, and the rainwater collection and circulating water supply pipelines are connected to the heat storage pool through the water pump. The invention is based on the principle of solar greenhouse effect~water-air film heat exchange~convective cycle, and intelligently controls the greenhouse environment; in the cold season, the airtight greenhouse and water-air film heat exchange store heat in water during the day and supplement CO to crops 2 At night, the water film radiates infrared heat to heat up the greenhouse. In the hot season, intermittent spraying, evaporation and heat absorption are used to enhance the ventilation and cooling effect. The "green and low-carbon" method of the present invention overcomes the problem of high cost of regulating the greenhouse environment in the prior art, has the effects of significantly increasing production and quality, reducing chemicals and saving water, and is conducive to the transformation and upgrading of facility agriculture.

Description

technical field [0001] The invention belongs to the technical field of solar heat utilization and greenhouse planting environment control, and in particular relates to an intelligent greenhouse and a planting environment control method that utilizes greenhouse effect heat collection and water-air film heat exchange with simple structure, easy realization and operation. Background technique [0002] Agricultural production is often rigidly constrained by adverse climates such as low temperature and frost, drought and little rain, and little sunshine. It has been difficult to get rid of the trouble of "depending on the weather" to varying degrees since ancient times. The rise of facility agriculture and greenhouse agriculture has enabled people to overcome the impact of adverse climate to a large extent, especially greenhouse heating and supplementary radiation measures have enabled off-season high-efficiency production to be realized. However, the heating process of the green...

Problems solved by technology

In order to obtain high-yield and high-quality results, it is often necessary to control the greenhouse environment by means of forced ventilation or heating, but due to high energy consumption and high cost, it is difficult to expand the application area

The air heating that has been promoted in recent years is indeed more environmentally friendly than fossil fuels, but there are also problems of high one-time investment, high energy consumption, and a sharp drop in energy efficiency ratio during low temperature hours at night
