The use of powder technology to enhance the performance of copper alloys in underground HVAC pipes. Powder technology, which includes processes like powder metallurgy and nanomaterial integration, allows for precise customization of copper alloys to meet specific requirements for subterranean HVAC systems. This research aims to develop more durable, long-lasting materials that ensure the reliability and effectiveness of subterranean HVAC pipes, offering insight into the cutting-edge methodology influencing the direction of subsurface HVAC systems. A pipe design with a diameter of 1in and a length of 500 mm was cast from copper powder materials, Cu and CuNiSiCr, to determine the differences in results. Three underground depths and powder thicknesses were used for pressure and powder thickness, with varying results for each depth. The depth of an underground pipe affects vertical force, stresses, and deformations in Cu powder. The deformation value increases with depth, reaching 0.57 mm at 3 meters. The stress increases with depth, reaching 0.54 MPa. The quality of CuNiSiCr powder improves with changes in powder quality, with deformation decreasing to 0.05 mm at 1 meter depth. Increasing copper powder tube thickness improves mechanical stress, with stresses nearly nonexistent at 3 mm thickness.
