Resum: In the last years we have witnessed a great advance in plastic crops, especially in cultivation techniques and plant improvements, but these advances have not been translated until recent days in an improvement of structures and climatic control due to the high costs of renovation of the structures. Therefore, this project is oriented towards this trend of continuous improvement in greenhouses, proposing the incorporation of air conditioning systems in the greenhouses to achieve more favorable conditions for cultivation. The next step is to achieve sustainable air-conditioning methods, which not only reduce CO2 emissions, but are economically viable, taking into account the high electricity prices which would increase the cost of production and reduce competitiveness of the product. In short, this project aims to contribute to the development of air conditioning methods for greenhouses with low environmental impact and reduced electricity consumption. For this, two possible alternatives are analyzed, one active, based on earth-air heat exchangers, and another passive based on phase change materials. For this, a detailed model of a greenhouse in the area of Almería will be made using Trnsys as a simulation tool to verify the feasibility of this type of equipment. The demands of heat or cold during a productive cycle and the efficiency of the equipment to be installed will be studied. The study will focus mainly on the winter period which is the productive time of greater economic profitability. For the two proposed solutions, the minimum temperature control capacity will be analyzed and the equipment will be dimensioned to avoid that the temperature inside the greenhouse is below 8 ºC.
