Description
technical field [0001] The invention relates to a pore groundwater circulation heating system assisted by a solar energy water source heat pump, in particular to a pore groundwater circulation heating system for heating by solar energy cleaning and utilization of pore groundwater, and belongs to the field of comprehensive utilization of solar energy and pore groundwater clean energy. Background technique [0002] Shallow-layer low-temperature geothermal resources use groundwater as a carrier, heat up through water source heat pump units, and are used in human production and life. They are renewable and non-polluting, and have broad development prospects. Restricted by the hydrogeological conditions of the porous aquifer and the recharge equipment, the water source heat pump heating system generally arranges the number of production wells and recharge wells in a ratio of 1:4 to maintain the balance of production and irrigation. Smooth recharging, resulting in high project inv...
