Automatización y control de temperaturas bajas en invernaderos

The need to improve processes in the world of agriculture makes it necessary to implement current techniques to control low temperatures, these affect the optimal development of plants that are grown in greenhouses. In the central part of the country the well-known frosts occur, these are the main causes of economic losses due to damage to the crops, the need to study mechanisms to stabilize the low temperature and at the same time avoid the use of fossil fuels by taking advantage of geothermal heat from the ground. The project is based on the design, construction and analysis of the behavior of low temperatures inside a greenhouse, which is used for practices in the Agronomy career at the Technical University of Cotopaxi. The system consists of an underground pipe that It was installed at a depth of 1.5 m to capture the geothermal heat and thus regulate the temperature by entering the air through the tubes, into the interior of the greenhouse. This allowed us to take advantage of the stable soil temperature of 15º, the fan installed in one of the pipes will be in charge of sending forced air to prevent the temperature drop from being abrupt, this works through an on-off controller that is set to start operating, as a result it was possible to raise at 3.3ºC during the monitoring of one day, in the early morning hours, this allows the crops to be within an ideal temperature for their correct growth.
