Enthalpy-based ground heat exchanger (ghe) performance test instrument system

An enthalpy-based ground heat exchanger (GHE) performance test instrumentation system for connection to a ground heat exchanger (GHE) installed in a deep Earth environment during performance testing operations, said enthalpy-based GHE performance test instrumentation system comprising:

• a fluid pumping module for pumping, at controlled flow rate, aqueous-based heat transfer fluid through a test ground loop in which a GHE installation is installed, during performance testing operations, wherein said GHE installation includes inlet and outlet ports for connection to said enthalpy-based GHE performance test instrumentation system;
• a fluid heating module for heating, to a controlled temperature, said aqueous-based heat transfer fluid being pumped into said GHE installation, so as to control the temperature of aqueous-based heat transfer fluid entering said GHE installation during performance testing operations;
• a data logger/recorder for logging and recording data collected from temperature and pressure sensors installed at the inlet and outlet ports of said GHE installation, and indicative of temperature and pressure of aqueous-based heat transfer fluid entering and exiting from each said GHE installation during performance testing operations;
• a computer system running an enthalpy-based GHE performance calculation program for processing said data collected by said data logger/recorder, and calculating enthalpy-based performance measures for said GHE installation based on said data collected by said data logger/recorder;
• and
• a wireless radio frequency (RF) based transceiver for wirelessly transmitting data from said computer system to a remote wireless RF transceiver station, for reception by said remote RF transceiver station and stored for subsequent processing and display.
