Description

A positive pressure ventilation cooling system for tomato

technical field

The utility model relates to the technical field of greenhouses, in particular to a positive pressure ventilation and cooling system for tomato.

Background technique

Due to the unique "greenhouse effect" of greenhouses, there is a greater heat load than ordinary buildings in summer. In high temperature weather where natural ventilation cannot meet the cooling demand, in addition to opening the curtain system, evaporative cooling is one of the most widely used and effective cooling technologies in modern greenhouse summer production environment regulation. Among them, the use of wet curtain fan negative pressure cooling system is the most common.

However, when the system is running, a temperature gradient will be formed in the direction of the airflow. The temperature near the wet curtain is lower, and the temperature near the fan is relatively high. The distance between the wet curtain and the fan surface is limited. Not only that, the cooling effect of multi-span greenhouses used for the efficient cultivation of hanging vine crops such as tomato is also affected by the shading of plant branches and leaves, resulting in a smaller effective cooling distance and a large difference in temperature distribution in the greenhouse, which eventually leads to inconsistent crop growth. , increasing the difficulty of cultivation management.
