Technical Field

[0001] This utility model relates to the field of energy-saving temperature control technology for water systems, and in particular to a temperature control and energy-saving device for circulating water systems. Background Technology

[0002] With the acceleration of industrialization and urbanization, energy consumption and environmental pollution problems are becoming increasingly serious.

[0004] Inability to flexibly regulate water circulation: Traditional systems lack effective temperature monitoring and regulation methods, making it difficult to achieve dynamic control of circulating water, which affects production efficiency and equipment lifespan. Utility Model Content

[0007] The water inlet pipe is equipped with a temperature sensor and a circulation pump.

[0008] Furthermore, one end of the water outlet pipe is connected to the condenser outlet via a flange, and the other end is connected to the cooling tower inlet via a flange.

[0009] The electric outlet valve is installed between the cooling tower and the circulation pipeline.

[0035] Working principle

[0036] An open-loop circulating cooling water system is used to cool the condenser of a refrigeration unit. The condenser transfers heat to the circulating water through contact heat transfer. A circulating pump then pumps the heated water to a cooling tower, where a cooling tower fan carries the heat outdoors, achieving the cooling purpose. When the refrigeration unit is under low load or shut down, the heat generated is relatively reduced, eliminating the need to start the cooling tower fan. By adding a temperature sensor to determine the circulating water temperature, when the temperature exceeds a set value, the cooling tower inlet electric regulating valve opens, allowing cooling through the cooling tower. When the temperature falls below the set value, the bypass pipeline electric regulating valve opens. Simultaneously, the valve opening is adjusted according to the temperature, achieving energy-saving functionality and flexible control.
