Optimized Control Method for Geothermal Heat Pump System

摘要

The invention and the load; Variable speed compressor, the direction switching valve, the heat source side heat exchanger, a heat pump unit and provided with an expansion device and a load-side heat exchanger; Buried in the ground and underground heat exchanger and having a bore hole assembly with a plurality of boreholes which are arranged at a predetermined distance from each other and having a feed pipe for ground-exchange tube passing cycle number; Number of cycles to ground passing through the heat-source heat pump cycle to the variable speed type to circulate circulating underground group the underground heat exchanger; relates to the optimal controlling method of a geothermal heat pump system including a plurality of bores forming the bore hole assembly S10 assigning a weight value of the high side is as small as to face each other with respect to the hole; S20 determining a total flow rate of the circulating an underground circulating the ground as the heat exchange capacity on the basis of the load change; S30 determining a number of bore holes passing underground cycle number according to the number of the total flow rate determined by the geological circulation step S20; Include; but selecting the bore hole in the underground boreholes aggregate supply cycle number determined according to the number of bore holes in the step S30, the bore hole in order to select the weight value is assigned to the high step S40 the number of circulating underground circulation which is characterized in that. ;
