Centralized heat source side water supply system for water source heat pump unit

The invention relates to a centralized heat source side water supply system for a water source heat pump unit. The centralized heat source side water supply system comprises a pipeline communicating with multiple water sources. The pipeline is embedded underground in the horizontal direction, and the embedding depth of the pipeline is below the static water level of the located region; multiple technological wells are arranged on the pipeline at intervals and used for pipeline construction, radiation pipe construction, water taking and natural water supplementing, and valves are mounted on the portions, communicating with the technological wells, on the two sides of the pipeline; and radiation pipes with valves are arranged at the bottom, close to a water source ground water source, of each technological well, one end of each radiation pipe is connected with the water source ground water source, and the other end of each radiation pipe is connected with the corresponding technological well.
