Abstract

The invention relates to a greenhouse vapor condensing irrigation system based on a radiation refrigerating principle. There are two embodiments suitable for different circumstances. The system comprises a greenhouse, a vapor condensing device, a fan, a power supply device and an irrigation device, crops are planted on the ground in the greenhouse, the vapor condensing device is mounted in the greenhouse or below a crop root system soil layer, the power supply device is electrically connected with the fan, an air outlet of the fan is connected with an inlet of the vapor condensing device, andan outlet of the vapor condensing device is communicated with the irrigation device. The system has the advantages that aiming at the problem of water-saving irrigation of the greenhouse, the radiation refrigerating principle is adopted to create a low-temperature environment, and condensed vapor is stored for utilization, so that the objectives of economically recycling water resources in an environment-friendly manner and effectively increasing water resource utilization rate are achieved; the vapor condensing device depends on radiation refrigerating, thereby being free of energy consumption and pollution and conforming to a concept of low-carbon sustainable development.

Description

technical field [0001] The invention relates to the technical field of water-saving irrigation, in particular to a water vapor condensation irrigation system for greenhouses based on the principle of radiation refrigeration. Background technique [0002] The current shortage of agricultural water in our country is obvious. At present, the ways to save and use water resources reasonably are mainly technologies and methods such as engineering water saving, biological water saving, agronomic water saving and management water saving. Implementation of these technologies and methods. It has greatly improved the utilization efficiency of the world's water resources. But these are mostly limited to improving water use efficiency and efficiency by reducing water input and expenditure losses in crop production systems. How to recover crop evapotranspiration in situ has never been systematically considered. Achieve water recycling. In addition, most of these technologies have the ...
