Dynamic Analysis of Natural and Mechanical Ventilation of a Solar Greenhouse Combining Controlled Mechanical Ventilation with a Ground-To-Air Heat Exchanger

Analysis of different air conditioning systems in a solar greenhouse realized in a warm temperate climate. In summer, the exploitation of the soil by means of a ground-to-air heat exchanger gives excellent results by reducing temperature peaks by up to 5 °C, compared to the use of a traditional mechanical ventilation system. In winter, even if the ground-to-air heat exchanger is not the solution that raises the temperature more during the day, its use allows to flatten the thermal wave more.
