Application of water cool storage systems in energy saving transformation of public buildings

 Presents the application of the water cool storage technology in the air conditioning system using large water chillers in the area of peak-valley electricity price. Making use of the peak-valley price difference of the power system, the low-valley electricity is used to store the cooling capacity produced by the refrigerator in the form of low-temperature water at night, which is released at the peak of electricity price to reduce the operating cost of the air conditioning system. Taking a specific project as an example, uses the original fire spare pool of the project to carry out energy saving transformation, adopts the screw electric refrigerator equipped with open water storage system for summer refrigeration, and calculates the overall energy consumption level of water cool storage system. Analyses and compares the energy consumption of the water storage system with that of the conventional air conditioning system, and calculates transformation cost, energy saving and investment payback period.
