Energy efficiency investigation and energy saving analysis of ground-source heat pump in cold zone

Obtains the energy efficiency ratio of ground-source heat pump (GSHP) systems in summer and the coefficient of performance in winter by testing 74 GSHP projects in cold zone. Analyses the application effect and existing problems of different GSHP projects. Calculates conventional energy alternative amount of the GSHP projects and obtains fitting formula between the project scale and the conventional energy alternative amount by data regression, which can provide a reference for similar projects.
