A multi-energy complementary heat pump system, including a ground source heat pump unit, is provided with at least one ground source side water circulating pump on the ground source side inlet pipeline of the ground source heat pump unit, and a pressure balance valve a is connected in series between the ground source side water circulating pump and the ground source heat pump unit, the water inlet pipeline on the ground source side is also connected with the air source heat pump energy supplement branch and the air heat energy and the solar energy supplement loop through the heat exchanger and the air source heat pump energy supplement branch. The utility model relates to a multi-energy complementary heat pump system, in which a supplementary energy module is arranged on the heat source side, integrating a ground energy heat pump unit, a water pump, an air source heat pump, an air heat energy collection heat exchanger and a solar energy collector, when the temperature of the heat source side of the local energy-source heat pump unit is low, the intelligent control system can reasonably open each energy supplement module for energy supplement work, thus ensuring the safe and stable operation of the ground-source heat pump unit.
