Cold storage technology is useful to alleviate the mismatch between the cold energy demand and supply. The integration of cold energy storage in cooling system is an effective approach to improve the system. . ••Component, applications, and operation control of CTES system are. . In recent years, energy consumption is increased with industrial development, which leads to more carbon dioxide (CO2) emissions around the world. High level of CO2 in the atmo. . The cooling system with cold storage unit mainly consists of refrigeration or cooling equipment, cold storage equipment, auxiliary equipment and the connection between the equi. . Cold storage systems can be coupled with both passive and active cooling systems. Hence, cold storage unit can also be divided into two main categories according to the driven ene. . 4.1.

Armin et al. combined ethylene glycol and water instead of ethylene as PCM for cooling system, thus further optimizing the energy consumption of the storage and cooling capacity of the storage and cooling system, which makes the system energy consumption only 63 % of the energy consumption of the system without PCM.
Constraints The optimal control of a water-cooled central cooling system is a typical constrained optimization problem because the system or components confront various limitations. The commonly used constraints are summarized below. 3.4.1. Satisfying the cooling demand
Due to the common use of water-cooled central cooling systems in energy-intensive buildings, improving the energy efficiency of the central cooling system is crucial for building energy conservation. Using energy-efficient equipment is an essential measure for reducing the energy consumption of the central cooling system.
The circulating cooling water system is developed by the direct-flow cooling water system, which saves water enormously by recycling the cooling medium. The system generally includes: water supply pumps, heat exchangers, cooling towers, valves, pipes and other minor components.
The supervisory control determines the operation mode and specifies setpoints for the local control loops. The local control adjusts the sequences and processes of relevant equipment to maintain the operation mode and setpoints determined at the supervisory control level. Fig. 2. The control structure of water-cooled central cooling systems.
In the reviewed studies, the system-model-based method is still the major solution for optimizing the control of the water-cooled central cooling system, as 83.7% of reviewed papers used this kind of approach. In recent years, data mining and reinforcement learning methods have been gradually used in this field. Fig. 5.
