Operational characteristics of multi-energy complementary heating system of middle-deep ground source heat pump
The model of the middle-deep coaxial borehole buried pipe heat exchanger is coupled with TRNSYS,and on the basis of this model,a multi-energy complementary heating system is formed with the solar collector-tank and gas boiler.The matching rela-tionship between the system and the building load is simulated,and the influence of the control strategy on the operation characteristics of the system is analyzed.This study pro-vides a feasible operation scheme for the engineering practice of multi-energy complemen-tary heating system of middle-deep ground source heat pump.
