Technical Field

Background
The cooling water circulation system refers to a water supply system for cooling water to exchange heat, reduce the temperature and recycle, and comprises an open type and a closed type.
The cooling apparatus is divided into an open type and a closed type, and thus the cooling water circulation system is divided into two types, i.e., an open type and a closed type. Open systems are complex to design and operate.
And (3) opening: the cooling equipment comprises a cooling pool and a cooling tower, and the water temperature is reduced mainly by means of water evaporation. Furthermore, cooling towers often use fans to facilitate evaporation, and cooling water is often lost. The open cooling water circulation system must be replenished with fresh water. As evaporation, the circulating water is concentrated, the concentration process will promote salt scaling (see deposit control). Make-up water has a diluting effect and its flow rate is often determined based on the circulating water concentration limit.
And (3) closed type: the closed cooling water circulation system adopts closed cooling equipment, circulating water flows in a pipe, and the outside of the pipe is usually radiated by wind. Except the leakage of the materials of the heat exchange equipment, no other factors change the water quality of the circulating water. In order to prevent salt scale from being caused in the heat exchange equipment, sometimes the cooling water needs to be softened (see softening of water).
The patent publication No. CN202110087613.3 discloses a cooling circulating water system and a control method thereof, which can meet the requirements of a user side and an energy consumption side simultaneously by uniformly monitoring and managing the pressure difference, the temperature and the pressure, the ambient temperature and the flow of the cooling circulating water system, and manage the comprehensive energy consumption while ensuring the normal use of the user side, thereby ensuring the lowest comprehensive energy consumption.
