Water source side control system of water source heat pump

The utility model provides a water source side control system of a water source heat pump, which comprises a heat source well and a water source heat pump unit, the water source heat pump unit is arranged outside the heat source well, a submersible pump is arranged inside the heat source well, and a water outlet of the submersible pump is communicated with a water supply pipeline. The water supply pipeline is communicated with a water inlet of the water source heat pump unit through a water treatment system. According to the water source side control system of the water source heat pump, the water pumping function and the recharging function of the heat source well can be interchanged, so that the safety of the water source side system is improved, the stability of the water source side system in use is improved, stable operation of the water source heat pump system is guaranteed, and the submersible pump can achieve a better frequency conversion effect; finally, system stability is achieved, initial investme
