The most prominent problems in application of groundwater source heat pump system are the low efficiency of recharge and groundwater resources waste. It was found in the heat source well with water source heat pump construction in a residential district of Anyang and the recharge tests, one of primary causes of low recharge efficiency was the unreasonable design and construction technology for heat source well. By increasing the number of bridge strainer, the height, particle size of filter media and gravel-fill thickness, single-well recharge increased significantly and 1∶1 effect of pumping and recharging was realized. In this case, low efficiency of recharge and groundwater resources waste are overcome and the project investment and operating costs are significantly reduced.
