Description

In this project, air conditioning has been simulated in a greenhouse. Greenhouses are environments built to cultivate plants under favorable humidity, temperature, and suitable light conditions. These environments are used to produce agricultural products in seasons with harsh weather conditions. One of the advantages of using greenhouses is that the internal conditions can be controlled and adjusted, so the optimal conditions for plant growth and development can be provided. Heating systems, air conditioning, irrigation systems, and lighting systems are used in greenhouses to provide suitable conditions for plant growth. Due to the control of environmental conditions, various agricultural products can be grown in greenhouses. The use of greenhouses is of great importance due to the reduction in water needs, reduction of product losses, increased efficiency, and increased lifespan of plants. Additionally, greenhouses can help reduce carbon dioxide emissions and improve air quality.

However, as agricultural production in greenhouse conditions is costly and requires special equipment, the prices of products produced in greenhouses may be higher than those produced in open spaces. Nevertheless, agricultural production in greenhouse conditions is considered a solution to the problems of agricultural output in open spaces. In open spaces, agricultural products face weather conditions that may reduce their performance and quality. In addition, due to soil erosion and decreased fertility in open spaces, agricultural production in such conditions faces natural challenges.

Alongside these advantages, agricultural production in greenhouse conditions is also considered a business opportunity for farmers and investors.

Method:

In this project, radiation modeling has been performed using the Discrete Ordinate (DO) model. This model has higher accuracy than other radiation models and is suitable for simulating complete radiation. However, it also has a higher computational cost compared to other models.

The geometry of this project has been created using the software Space Claim. The meshing of this geometry has been performed using Ansys Meshing software, and the number of elements used for this project is 292102. For this greenhouse, a fan is assumed to be placed on the left wall, which brings air into the greenhouse at a velocity of one meter per second. A window has also been considered in the right wall for air to exit.

Result:

After simulating and converging the residuals, we can see the velocity, pressure contours, and radiation-related parameters.
