Double-system circulation water cooling device

Abstract

The invention relates to a double-system circulation water cooling device. The device comprises a cooling unit, a freezing unit and a control unit, wherein the cooling unit comprises a first cooling tower, a second cooling tower, a cooling water tank and two workshop circulating water supply pipes; the first cooling tower and the second cooling tower separately communicate with workshop circulating water return water, the cooling water tank separately communicates with the first cooling tower and the second cooling tower, and the workshop circulating water supply pipes separately communicate with the cooling water tank; and the freezing unit comprises a freezing machine, a plate type heat exchanger, a cooling water circulation water pipe and a freezing water circulation water pipe. Compared with the prior art, the double-system circulation water cooling device has the advantages that the freezing unit can be automatically started or closed through a temperature sensor and an electric controller according to circulating water cooling temperature requirements; different circulating water cooling quantity requirements can be met, and working modes can be flexibly switched according to the variation of actual production requirements; the refrigerating quantity of the freezing unit is reasonably utilized, and coordination between production requirements and energy consumption reduction is realized; and the device is great in working stability and long in service life.

Description

technical field [0001] The invention belongs to the technical field of workshop circulating water cooling, and relates to a dual-system circulating water cooling device. Background technique [0002] The circulating water returned from the workshop is generally cooled by the cooling tower, and then re-transported to the workshop to provide cooling capacity for the equipment in the workshop. When the cooling capacity required by the circulating water is small, the cooling of the circulating water can be realized by using a cooling tower. However, if the cooling capacity required by the circulating water is large, the cooling tower cannot provide sufficient cooling capacity for the circulating water. Therefore, some factories use refrigerators to cool the circulating water. Due to the large power consumption of the refrigerator, if the refrigerator is used for refrigeration for a long time, the energy consumption will be greatly increased, and the production cost will be too ...

AI Technical Summary

Problems solved by technology

Due to the large power consumption of the refrigerator, if the refrigerator is used for cooling for a long time, the energy consumption will be greatly increased, and the production cost will be too high

In addition, if the cooling temperature of the circulating water will often change according to the actual production needs, the cooling capacity required for the circulating water will change more frequently. , it will waste more cooling capacity of the refrigerator, resulting in a huge waste of energy
