Abstract: This paper analyzes the difficulties of exact solution of existing ground thermal properties heat transfer models, discusses the method for determination of the GSHP system ground-coupled pipe’s heat exchange capacity, and establishes the modification model for metering error of integrated ground thermal resistance and analysis system for its exact solution. A new test instrument and analysis software are developed to test and analyze a number of actual projects, and get the curve of the heat exchange capacity of unit hour and unit meter of the closed-loop ground-coupled pipe and its recommendation value for design.Then further discusses the method and operation steps for the calculation of pipe design and performance evaluation.
Key words: Ground thermal properties, Thermal response test, Metering model of integrated ground thermal resistance, Error analysis system, Heat exchange capacity of unit hour and of unit meter, Operation steps
