Compared with the ice storage cold source system, the water storage cold source system with the same storage capacity ( ).

Compared with ice storage cold, water storage cold features: ① system efficiency comparison, water storage cold can save refrigeration electricity more than 10%, ice storage cold electricity consumption is higher than conventional air conditioning about 1/3. Water storage tanks can be implemented in summer cold storage, winter heat storage, to achieve cold storage, heat storage dual-use, while ice storage is impossible to do; ② system cost and running electricity cost comparison, ice storage of total investment than the large temperature difference water storage cold is much larger, so the domestic operation of the ice storage system basically about 1/3 peak shaving operation, otherwise, it will be a large increase in the cost of the project; ③ applicability of the comparison, the water can be used in the new water storage cold project, can also be used for renovation projects, ice storage cold is higher than conventional air conditioning about 1 / 3. It can also be used for renovation projects, and ice storage is only suitable for new projects; ④ Comparison of operating costs, water storage running costs are low, and the response speed is fast; ⑤ Water storage system covers a large area due to the large volume of cold storage tank.
