The water storage tank or tank for water cold storage has the defects that the water storage tank or tank is large in volume, only can control temperature and cannot control humidity due to the fact that only sensible heat of water is utilized and the temperature difference of supply water and return water is small. The flow state ice storage technology is that the dual-working-condition refrigeration main machine runs at the off-peak time period to produce ice slurry by 3.5 percent of ethylene glycol, and is used at the peak time period of the electricity price.

Therefore, a central air conditioning system for water cold/heat storage and flow state ice storage with independent temperature and humidity control needs to be designed to solve the problems of single temperature and humidity control, large occupied area, high manufacturing cost and high operation cost of the existing air conditioning system.
