The Position Angle of a Greenhouse Roof Vent

greenhouse roof vent

A greenhouse roof vent allows cool air to enter the house on warm days, reducing temperature and humidity levels inside. This allows for better crop growth. However, there are a number of disadvantages to using a roof vent.

The ventilation of the greenhouse window mainly depends on the wind and the difference between the indoor and outdoor temperatures. The prevailing summer wind blows from the windward side of the house, creating a pressure difference that causes air to flow towards the leeward side. This ventilation process is most efficient when the roof vents are oriented to match the summer wind direction. However, this effect is often reduced when the ventilation system is not complemented by side or end wall louvers.

Moreover, the performance of the roof ventilation system is affected by the position angle of the greenhouse. Therefore, it is crucial to determine the optimum position angle of the greenhouse roof vents. In this article, the effects of a proposed front bottom + top and back roof (FTB) and a traditional front bottom + top (PW) ventilation structures on the airflow patterns and thermal behavior in an arched greenhouse are assessed using CFD simulation.

The results show that a roof vent with a position angle of 85° is the most suitable ventilation structure for an arched greenhouse to provide an effective cooling environment. The proposed design RS is found to be more favorable than PW with a position angle of 75° due to the improved interaction between the ventilation stack and the prevailing summer wind.

Choosing a Vaporizer


Vaporizers are a form of inhalation device that produces vapor from a substance like herbs, wax or oils. They are a healthy alternative to smoking cigarettes or other tobacco products, and also help smokers quit. Read more:

When choosing a vaporizer, you’ll want to think about what you plan on using it for and how often. You’ll also need to know how long the battery will last between charges, as some vaporizers can run out of power much faster than others.

You’ll also want to check whether the vaporizer has an adjustable temperature control or presets, as different herbs will release terpenes and other phyto materials at different temperatures. Lower heat preserves the taste of a flower, while higher temperature can lead to bigger clouds of vapor.

Portable vaporizers typically have a single button that powers up the unit and toggles through various temperature options. Precision temperature units offer a more comprehensive set of options to allow users to dial in their exact vapor experience. This style is often preferred by those looking for a more robust experience with their vaporizer, or those who enjoy having full control over their sessions.
