Study on the Influence of Solar Array Tube on Thermal Environment of Greenhouse

Abstract

The stratum and microenvironment temperatures in a greenhouse are important factors that affect crop yield. In order to solve the problem of temperature imbalance caused by solar radiation in greenhouses, this paper proposes the application of a solar radiation array tube in a greenhouse. By adding water or phase change materials to the array tube, the influence of the array tube on the formation and microenvironment temperature changes was studied, and a 10-day test was carried out. A test group and control group were set up to monitor test results, and the ground was divided into six areas. The depths of each area were 10 cm, 30 cm, and 50 cm, and the heights of the greenhouse centers were 0 cm, 30 cm, 60 cm, 90 cm, 120 cm, 150 cm, and 180 cm. Via an analysis of the test results obtained for the formation and microenvironment temperature, the arrangement of the array tube was found to exert a constant temperature regulation effect on the microenvironment of the greenhouse at a formation depth of 10 cm and was able to improve this formation depth to a certain extent. The temperature at 30 cm and 50 cm plays a positive role in building a good vegetation growth environment.

“…Besides, the two peaks at 781.2 and 796.4 eV are attributed to the 2p 3/2 and 2p 1/2 peaks of Co 2+ in Co 3 O 4 , respectively. 31 In the Ti 2p spectrum, the two peaks are located at 459.2 and 465.0 eV, which correspond to 2p 3/2 and 2p 1/2 of Ti 4+ of TiO 2 , respectively (Fig. 2c).…”

Research Status and Prospects on the Construction Methods of Temperature and Humidity Environmental Models in Arbor Tree Cuttage

“…The heat transfer of the substrate is mainly through heat conduction and heat radiation. Light intensity has a certain influence on the temperature of the substrate [120] because the absorption and reflection of light by the substrate will cause itself to be heated [121]. The color of the substrate affects the effect of heat radiation energy transfer because the color of different types of substrates has a different ability to absorb and release heat.…”
