Each crop shall have its own climate conditions to grow in a good environment. In response to that, Hortinergy takes into account 3 settings : heating, humidity and vents opening.
Heating system will be activated to prevent the inner temperature to drop below these settings. Then, due to insolation, inner temperature could go up fast. In that time, vents opening settings will be turned on to cool the inside of the greenhouse.
When humidity is higher than the settings, vents, active ventilation or dehumidification are activated.
Heating settings
Heating system is turned on when temperature will not drop below the required inner temperature of the greenhouse.
Hereabove the different temperature regulation modes :
- Constant during a period
First, the “Constant during a period” option, as indicated, means that the minimum temperature to heat the greenhouse during a day will be the same. However inner temperature can be higher due to external clilmate. Mostly used for pot plants.
2.Day-Night
Then, with the “Day-Night” option, you need to insert the minimum required inner temperatures during the day and night. It is based on two parameters : the delta temperature inside/outside and the solar radiation, which will be used to deploy the thermal screen. Daytime setpoint temperature is usually higher than nightime one, so as to ensure a good growth of the crop and a better return on energy saving. Mostly used for the crop of cannabis.
3.Pre-Post night
Finally, the “Pre-Post night” option is used to split the night in two. For instance, if the night lasts 8 hours, it will be composed of a 4 hours pre-night, followed by a 4 hours post-night. Pre-night setpoint temperature is usually lower than post-night one. Mostly used for tomato crop.
The duration of a period is set by the customer. For instance, a period may be from 12/01/2021 to 13/01/2021 or from 15/03/2021 to 18/09/2021. Moreover, in one year, 6 periods may be chosen.
