Greenhouse underground water micro-fog water-cooling temperature control device

Abstract

The invention discloses a greenhouse underground water micro-fog water-cooling temperature control device and belongs to the technical field of modern agriculture. The greenhouse underground water micro-fog water-cooling temperature control device comprises a greenhouse, an outer sun-shading system arranged outside the greenhouse, a blowing system and water-cooling system inside the greenhouse, and a micro-fog system to cool the inside of the greenhouse, wherein the micro-fog system decreases interior temperature of the greenhouse mainly through evaporative heat absorption by fog 50 mu m and below in size which is produced by underground water atomized by a micro-fog nozzle; in case of a high temperature, the water-cooling system decreases the ambient temperature of a condensing pipe through low-temperature underground water flowing in the spiral condensing pipe; cooled air around the condensing pipe is blown into the greenhouse through the blowing system so that interior temperature of the greenhouse is decreased; in case of a low temperature, the water-cooling system can heat the greenhouse through the spiral condensing pipe according to the characteristic that underground waterhas constant temperature throughout the year; air outside the greenhouse is blown in through the blowing system so that CO2 concentration in the greenhouse is changed, evaporation of fog in the greenhouse is accelerated, moist air and high heat in the greenhouse are brought away, and the interior temperature and humidity of the greenhouse are kept balanced.

Description

Technical field [0001] The invention relates to the technical field of modern agriculture, in particular to a micro-mist water cooling temperature control device for groundwater in a greenhouse. Background technique [0002] Greenhouse is a kind of device that can transmit light and keep warm. It is used to cultivate plants in the seasons that are not suitable for plant growth. It is suitable for flower cultivation, vegetable cultivation and other fields, and is mostly used for plant cultivation of temperature-loving vegetables, flowers, forests and other plants in low temperature seasons. Or seedlings, etc., are widely used in agricultural production. [0003] In the prior art, in order to meet the needs of plant growth in the greenhouse and avoid high temperature or low temperature affecting the growth of plants in the greenhouse, it is necessary to configure corresponding temperature control equipment. Common cooling devices are natural ventilation and external shading systems, ...

Problems solved by technology

[0003] In the prior art, in order to meet the needs of the growth of plants in the greenhouse and avoid the impact of high temperature or low temperature on the growth of the plants in the greenhouse, it is necessary to configure corresponding temperature control equipment. The common cooling devices are natural ventilation and external sunshade systems, and the heating devices are mainly Double-layer film covering and heating can also play an auxiliary temperature control role, but most of them are passive temperature control measures, the cooling or heating effect is relatively slow, and it is impossible to achieve fine control of the temperature in the greenhouse
