The utility model discloses a scattered type water-ring earth source heat pump air conditioning system capable of being used in a scattered manner. The prior water-ring earth source heat pump air conditioning system adopts conventional hot and cold sources, is low in efficiency and bad in environmental protection. The utility model is characterized in that a plurality of customer devices are connected with one end of a water transportation loop, the other end of the water transportation loop is connected with an earth source device, each customer device is made up of a customer heat pump and a customer water pump, and the earth source device is made up of an earth source heat exchanger and a system water pump. In the utility model, the on-off of a scattered type heat pump air conditioner can be controlled by a user individually and also can be controlled by a central control system uniformly, when being used individually, the scattered type heat pump is under an efficient work state so as to facilitate the account management, and meanwhile, and renewable energy source of shallow geothermal resource is used by the system at the same time, so that the utility model further improves the system efficiency, saves energy and protects the environment; and the construction and the operation are simple.
