Two methods for determining operation parameters of GSHP systems

In view of the uncertainty of operation parameter selecting criteria of ground-coupled heat pump systems, presents two comparing and design methods based on the annual energy consumption simulation and seasonal energy efficiency ratio (SEER) respectively, and compares the energy consumption of the ground-coupled heat pump system with that of the air-source heat pump system and water chiller plus boiler system to determine the proper design and operation parameters and to ensure the energy efficient effect of ground-coupled heat pump system. Taking a building in Nanjing as an example, calculates the appropriate SEER of the  system.
