Method of and apparatus for interfacing geothermal equipment (GTE) in a building with a ground loop heat exchanging (GLHE) subsystem installed in the deep earth environment outside of the building

摘要

A geothermal system including geothermal equipment (GTE) for transferring heat energy in a building. A ground loop heat exchanging (GLHE) subsystem is interfaced with the GTE, and a plate heat exchanger (PHE) for interfacing the GTE and the GLHE subsystem. The PHE establishes a first hydraulic loop between the GTE, and the PHE. The PHE established a second hydraulic loop between the GLHE subsystem and the PHE. The volumetric flow rate within the second hydraulic loop is greater or less than the volumetric flow rate within the first hydraulic loop. The PHE exchanges heat energy between the first and second hydraulic loops so that the GLHE subsystem is operated at inlet water temperatures that enable maximum heat transfer rate (HTR) performance when the GTE is fully loaded.
