Design and experiment of IOT cooling system in glass greenhouse based on CFD simulation

Abstract

In the summer heat season, the performance of greenhouse cooling system is the key factor of the greenhouse crop pollination and fruit formation. Scientific design of greenhouse cooling system and intelligent control of cooling equipment can ensure the normal growth of greenhouse crops and save energy. In this paper, the thermal equilibrium theory of greenhouse is analyzed, and the thermal environment model of glass greenhouse is established based on the theory of engineering thermophysics combined with greenhouse environmental regulation. This study uses CFD (Computational Fluid Dynamics) simulation technology to simulate the change of greenhouse temperature field and perform experimental analysis, and designs an intelligent greenhouse temperature control cooling system scientifically. It provides reference for the design of IOT (Internet of Things) cooling system in glass greenhouse in theoretical analysis and engineering practice.
