Operable vents, windows, and doors can promote convective air ventilation in your greenhouse. You should consider the ventilation design after the configuration is selected. Proper planning can provide fresh air and cooling to the living space.
The use of ridge vents, which are placed at the roof’s highest point, reduces the chance of the greenhouse overheating.
When hot air rises and becomes trapped in the peak of the roof, the ridge vents open via a motor or a pole operator and allow the hot air to escape convectively.
Multiple bays can be joined together, and the entire roof line can open. Windows and eave vents add natural air circulation and can draw cool, fresh air into the greenhouse while forcing hot air out through ridge vents. These components assist in circulation and temperature balancing within the greenhouse.
Ridge vents and windows can be mechanically controlled by a linear actuator motor. This motor is specifically designed for high humidity areas such as a greenhouse.
All controls are contained in weatherproof housing. Each vent operates based on temperature, which is read on a thermostat mounted in the greenhouse.
A signal is sent to the motor, which opens the vents when the thermostat reaches a designated degree.Correct thermostat placement is necessary to prevent false readings from direct sunlight or heaters.
Thermostats are set to operate based on a temperature range of approximately 5-10 degrees. For example, vents can be set to open when the greenhouse reaches 70 degrees and close when the temperature drops to 60 degrees.
The vents will remain open and allow air to circulate while the temperature is within this range. The vents can be forced to open manually if needed, but are intended to provide effortless natural ventilation to the plants and people inhabiting your space.
