'PROVISION FOR CLIMATE CONTROL IN GREENHOUSES AND SIMILAR STRUCTURES FOR CROP PROTECTION'.

摘要

Disposition for climate control in greenhouses and similar crop protection structures, designed to regulate the climate of said enclosures, by controlling the deficit of vapor pressure of the air, said deficit being the difference between the vapor pressure of the air and the saturation pressure at the temperature at which that air is, characterized in that it comprises a low-pressure "fog" system (1), composed of a network of pvc pipes (2), which are placed on top of each other. The crops, between which inserted a series of nozzles (3) that typically operate at four atmospheres, having a flow rate close to seven liters per hour, having a non-return valve (4), to achieve its pressurization, and a centrifugal pump (5) for the supply of filtered water to said network of pipes (2), a sensor (6) of humidity and temperature, as well as a controller module (7), constituted by a hardware and a firmware, which by means of the received reading of the sensor (6), it calculates by means of a proportional, integrative and differential algorithm, the vapor pressure deficit, compares it with the setpoint value and adjusts the duration of the pulses of the fog system (1) the relay is activated of the pump (5) that gives way to the water towards the nozzles (3).
