Abstract

This utility model discloses a four-source synergistic coupling heat pump system based on wind-solar hybrid power supply, including an air-source heat pump unit, a ground-source heat pump unit, a water-source heat pump unit, an energy storage tank, photovoltaic (PV) panels, a wind turbine generator, and a PLC control mechanism. The air-source heat pump unit is connected to the energy storage tank via a first circulation pipeline, the ground-source heat pump unit is connected to the first circulation pipeline via a second circulation pipeline, and the water-source heat pump unit is connected to the energy storage tank via a third circulation pipeline. The beneficial effects are: by coupling four types of heat sources—air, ground, water, and solar energy—and intelligently selecting the optimal combination, the limitations of a single heat source are significantly overcome, greatly improving the overall operating efficiency and stability of the heat pump system. It also captures data across multiple dimensions and environmental conditions on a broad scale and large scale, effectively improving the comprehensive utilization efficiency of thermal energy resources.
