摘要：
Optimization study of ground -source heat pump heating systems in extremely cold areas. Through the ground -source heat pump system built in extremely cold areas, the optimization of the heating conditions of system is researched. The results show that the average COP value of the system is increased by 9.8% when the system is intermittent in operations and the average COP of system is increased by 11.1% when two compressors operate and the irculating pumps adopt the inverter control. The average COP of the heat pump is increased by 4.3% when 3 compressors operate and the circulating pumps adopt the inverter control. This shows that the system optimization is very necessary with the ground -source heat pump system in severe cold regions, and can further improve the efficiency of system.
