Capillary network tail end water source heat pump (WSHP) central air conditioning system

The invention discloses a capillary network tail end water source heat pump (WSHP) central air conditioning system, comprising a water source heat pump (WSHP) set, a capillary network radiation cyclic system, a replacement fresh air dehumidification cyclic system and a temperature and humidity control system, wherein the WSHP set is communicated with the water inlet of the capillary network radiation cyclic system via a circulating pump, a water collector and a water segregator; external cold and heat sources are communicated with the inner cavity of a surface cooler via a circulating pump and a water inlet orifice, and go back via a water outlet orifice; and fresh air is communicated with an indoor air outlet through the surface cooler after heat exchange is realized between the refresh air and indoor return air via a plate heat exchanger. The invention has the advantages of higher temperature of cold water in summer, lower temperature of hot water in winter, high unit efficiency, stable and efficient operat
