PHYTOTRON Russian patent published in 2015 - IPC A01G9/26 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to climatic chambers for growing plants. The phytotron comprises a working chamber with the ventilation holes located in lower and upper parts, a temperature sensor placed in the working chamber, the racks formed with ventilation slots and windows for placing containers with plants, a highlighter mounted above the containers, comprising LED panels, and the highlighter control system. The LEDs are arranged in groups of LEDs with different spectral ranges, such as 400-500, 500-600, and 600-700 nm. The phytotron is equipped with the air-cooling unit with the shutoff unit. The panels are made of a thermally conductive material and provided with ventilation openings which are communicated with the air-cooling unit by the ventilation ducts. The temperature sensor is located at the location of the containers with plants and is connected to the air-cooling unit control system. The temperature sensor is located at the location of the containers with plants and is connected to the air-cooling unit control system.

EFFECT: implementation enables to stabilise the temperature at the location of the containers with plants regardless of the temperature of the outside space and the emission intensity of the LEDs; to stabilise cooling and the necessary temperature mode of LEDs operation and thus to ensure their high durability.
