Direct cool water supply cool-storage air conditioner system and its operation method

The invention discloses a cool storage air conditioning system providing cold water directly and the running method. Electric valve V1 is set at the front of branch road of outlet port of refrigeration host computer and connected pipe is set between the absorbing end of cold supply pump and the main return pipe at the end of air conditioner. Adjusting valve V3 is set on the connected pipe and adjusting valve V4 is set on the branch road of providing cold. By selecting open or close of said electric valve loop structures with various working station are composed to realize control for different running method to system. The invention is provided with compact structure, simple control and it can realize exchange of multiple running strategies. While requirement for external loading is satisfied, output cold quantity of refrigeration host computer and cold storage slot is assigned in reason. The utilization for cold quantity in cold storage slot is improved so as to transfer electric consumption in peat at the maximum extent and save running cost.
