UNDERGROUND PHASE CHANGE TEMPERATURE REGULATION METHOD AND APPARATUS

Disclosed is an underground phase change temperature regulation apparatus, comprising: a cooling end (3), a heat dissipation end (4), circulation mechanisms and a control phase change generation mechanism (5). The cooling end (3), the heat dissipation end (4) and the control phase change generation mechanism (5) are all in communication with the circulation mechanisms; a phase change medium is contained in the circulation mechanisms; the control phase change generation mechanism (5) is used to control the phase change medium to undergo an endothermic phase change at the cooling end (3), and is also used to control the phase change medium after the endothermic phase change to undergo a heat dissipation phase change at the heat dissipation end (4). By means of using the endothermic phase change, heat may be absorbed to lower the temperature, and an exothermic phase change may release heat to raise the temperature, thereby achieving heat transfer and temperature control. The described apparatus is suitable for c
