A passive planting greenhouse system

Abstract

The invention discloses a passive planting and breeding greenhouse system, which relates to the technical field of agricultural facilities. Specifically, it includes the greenhouse, the main water tank and the auxiliary water tank. The greenhouse includes a transparent main wall, and the main wall is hollow inside and forms a closed-loop heat exchange cavity. The main water tank is communicated with the lower cavity of the heat exchange cavity through a capillary tube. The upper end of the heat exchange cavity is connected to the main water tank through a first circulating pump, and the lower end of the heat exchange cavity is connected to the auxiliary water tank through a second pipe and a first valve. The auxiliary water tank is connected with the main water tank through a third pipeline, and the third pipeline is provided with a second valve and a first bypass branch in parallel with the second valve. A second circulation pump and a third valve are arranged on a bypass branch. The system can store excess heat during the day and release it at night, passively achieving temperature balance in the greenhouse.

Description

technical field [0001] The invention relates to the technical field of agricultural facilities, in particular to a passive planting and breeding greenhouse system. Background technique [0002] Greenhouses, also known as "greenhouses", are agricultural buildings that use highly translucent materials instead of walls and windows to absorb heat from solar radiation. Greenhouse is an agricultural facility that can ensure the normal growth of animals and plants during the growth and development period, and even increase the output in the season when the weather conditions such as temperature and humidity are not suitable for planting crops and raising animals by changing relevant parameters such as indoor temperature and humidity. [0003] The effect of air temperature and humidity on plant growth Temperature and humidity are very important for plant growth, and temperature has a great impact on plant photosynthesis and respiration. Temperatures that are too low delay plant gro...

AI Technical Summary

Problems solved by technology

[0004] At present, the ordinary three-dimensional greenhouse absorbs heat from solar radiation due to sufficient light during the day, resulting in high temperature, which requires ventilation and cooling; the temperature is too low at night, especially in winter nights, insulation measures need to be taken

This method of actively achieving temperature balance between day and night, on the one hand, increases operating costs and consumes more energy
