Abstract The earth-air heat exchanger is a geothermal heating and cooling system that uses the Earth as a heat source and receiver to heat or cool various buildings, includingcommercial and residential buildings, in different seasons. As well as many applications of earth-air heat exchanger systems, its design based on the heating and cooling needs of the building, climate change, and the amount of soil moisture is important. The right choice of design parameters saves the materials used and leads to optimal running and performance costs. In this study, the control volume model was used to simulate the model. In the present proposed model, air humidity and thermal penetration of heat into the soil are predicted. Then, by using the parameter optimization algorithm, it is selected so that we have the highest thermal efficiency according to the coldest day of the year, and by designing the exchanger based on the coldest day of the year, we can be sure that it will have an acceptable performance on other days of the year.
