Single-well power generation utilizing ground energy source

摘要

A ground energy collection system is disclosed. The system includes a well configured to absorb ground energy and provide the absorbed ground energy to a first heat transferring fluid. A pump is used to circulate the first heat transferring fluid to an evaporator. The evaporator is configured to: receive the first heat transferring fluid; facilitate heat exchange between the first heat transferring fluid and a second heat transferring fluid; and return the first heat transferring fluid to the well. A compressor then compresses the second heat transferring fluid. An electricity generator generates electricity based on the second heat transferring fluid received from the compressor. A condenser then retrieves heat and liquefies the second heat transferring fluid. An expansion valve is utilized to regulate pressure of the second heat transferring fluid received from the condenser and return the second heat transferring fluid to the evaporator.
