Abstract

The invention relates to a cooling system, a temperature control method, device, equipment thereof and an air conditioning system, and belongs to the technical field of temperature control. Temperature detection assemblies are arranged at water outlets of cooling devices of the cooling system, adjusting valves with the adjustable opening degrees are arranged at water inlets of the cooling devices, so that opening degree adjusting instructions are sent to the corresponding adjusting valves according to water inlet temperature values and preset water outlet temperature threshold values of the cooling devices, the opening degrees of the adjusting valves and the water inlet amount of the cooling devices are adjusted, the heat dissipation capacity of the cooling devices is adjusted, therefore, the outlet water temperature of each cooling device is consistent, the heat of the cooling system is balanced, and the stability of the system is ensured.

Description

technical field [0001] The invention belongs to the technical field of temperature control, and in particular relates to a cooling system and its temperature control method, device, equipment, and air-conditioning system. Background technique [0002] The cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it to the atmosphere to reduce the water temperature. The cooling tower plays an important role in the cooling system because of its good cooling effect. [0003] In the related art, in order to realize the cooling effect, it is often necessary to use multiple cooling towers in parallel in the cooling system. However, when multiple cooling towers are used in parallel, due to the difference in pipeline resistance, the water distribution of each cooling tower is different when the valve opening is the same, making it difficult to distribute water evenly, resulting in water discharge from each cooling tower. If the t...
