The invention belongs to the technical field of ground source heat pumps and particularly relates to a ground source heat pump air conditioning system based on independent temperature and humidity control. The ground source heat pump air conditioning system based on independent temperature and humidity control solves the technical problem that the design is not reasonable enough in the prior art. The ground source heat pump air conditioning system based on the independent temperature and humidity control comprises a heat pump main body, wherein a cooling water circulation heat exchange subsystem and a freeze water circulation heat exchange subsystem are connected to the heat pump main body, a temperature processing subsystem and a humidity processing subsystem connected to the temperature processing subsystem are connected to the freeze water circulation heat exchange subsystem, the cooling water circulation heat exchange subsystem and the freeze water circulation heat exchange subsystem are connected, and a heat exchange mechanism is arranged between the cooling water circulation heat exchange subsystem and the freeze water circulation heat exchange subsystem. Compared with the prior art, the ground source heat pump air conditioning system based on independent temperature and humidity control has the advantages that the refrigeration load and heating load of the heat pump main body are reduced, the condensing temperature or the evaporating temperature of the heat pump main body can be more appropriate, and thus the working stability of the heat pump main body is improved.
