The invention relates to an indoor central cooling system in summer using underground water as refrigerant. Underground water provided by a water supply well subsystem is conveyed into indoor cold-heat exchangers of many users which are in parallel connection or multi-level parallel connection in a water supply network and a water return network through the water supply network and a pressure pump station; cold-heat exchange is carried out for the underground water and the indoor heat air; and then the underground water is conveyed to a water return well subsystem through the water return network and the pressure pump station to be injected underground or discharged into ponds, lakes and sight rivers or be used for fresh water aquaculture to beautify the environment and permeate underground. In the cooling period in summer, the invention incessantly supplies the underground water for the indoor cold-heat exchangers for 24 hours per day, thereby achieving ideal refrigeration effect.
