Geothermal energy combined operating system

Abstract

The invention discloses a geothermal energy combined operating system. The geothermal energy combined operating system comprises a medium deep stratum geothermal downhole heating supply system, a shallow stratum buried pipeline system, a transition season circulating pipeline, a heat pump unit, in-house circulating pipelines and a building terminal thermoregulation system. The in-house circulatingpipelines comprise the winter circulating pipeline and the summer circulating pipeline. The medium deep stratum geothermal downhole heating supply system and the shallow stratum buried pipeline system communicate with the building terminal thermoregulation system through the heat pump unit and the in-house circulating pipelines. Heating and cooling are alternately implemented by regulating valveson the corresponding pipelines to be turned on and turned off. According to the geothermal energy combined operating system, the medium deep stratum geothermal downhole heating supply system can getmedium deep stratum geothermal heat energy on the premise of only using heat and not using water and makes full use of the medium deep stratum geothermal heat energy to supply heat to a ground building in winter; the shallow stratum buried pipeline system makes full use of shallow soil to provide cold energy for the ground building in summer. Tkothermal energy combined operating system is ingenious in design, reasonable in layout, safe and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of geothermal utilization systems, in particular to a geothermal energy composite operation system. Background technique [0002] In recent years, the pollution of the air environment has been serious, and the problem of smog control has become increasingly prominent. The extensive development of traditional energy is no longer advisable, and it is urgent to vigorously develop clean energy. Under the background of the increasingly intensified energy crisis and increasingly urgent environmental protection, improving energy utilization efficiency, developing new energy to replace traditional energy, and reducing environmental pollution have become a top priority. [0003] Geothermal resources not only do not pollute the environment, but also can be applied all-weather and all-time. It has the characteristics of green and low-carbon, large reserves, wide distribution, good stability, and high utilization coeffi...
