Abstract
This research simulates a geothermal heat pump system needed to grow hemp plants for medical applications in Ardabil, Iran. Supplying energy for the cultivation of hemp plants can sometimes impose many costs. On the other hand, it is impossible to ignore the release of carbon dioxide to produce energy for the cultivation of this plant. In this regard, in this article, we will check the performance of a geothermal heat pump system and evaluate its output for cultivating the Hemet plant in the greenhouse. The results show that considering the cultivation of industrial hemp twice a year, the equivalent of 17.74 to 26.62 tons of carbon dioxide is saved per hectare. According to the 4 hectares under cultivation in the designed greenhouse, a figure equal to 70.96 to 106.48 tons of carbon dioxide per year is stored due to hemp plant cultivation in the greenhouse. In addition, using a heat pump system equivalent to 6.64 tons of oxide prevents the emission of greenhouse gases through renewable energy, which creates a negative carbon greenhouse system. Also, the heat capacity of the geothermal pump to supply energy to the greenhouse is equal to 570.2 kilowatts, which is dependent on the height and optimal temperature of the greenhouse. With the increase of these design parameters, the required heat capacity also increases.
