Embodiment 1

[0022] see figure 1 , a kind of anti-low temperature cooling water system A100 provided in this embodiment includes: cooling unit 30, water inlet pipeline, water outlet pipeline, connecting pipeline, cooling tower 40, cooling filler 41, first temperature sensor, second temperature Sensor, third temperature sensor, pressure sensor, first butterfly valve 2, second butterfly valve 11, third butterfly valve 12, pressure gauge 3, thermometer 4, automatic air release valve 5, check valve 6, drain valve 8, Y-type filter Device 9, water flow switch 10, proportional bypass valve 13 and ball valve 14.

[0023] One end of the cooling unit 30 is connected to the water inlet pipeline, the other end of the cooling unit 30 is connected to the water outlet pipeline, and the two ends of the connecting pipeline are respectively connected to the water inlet pipeline and the water outlet pipeline. The water pipeline is connected, the end of the water inlet pipeline away from the cooling unit 30 ...

Embodiment 2

[0032] Please refer to figure 2 In this embodiment, the difference from Embodiment 1 is that a three-way electric regulating valve 25 is provided at the branch node of the anti-low temperature cooling water system B200 provided in this embodiment. The three-way electric control valve 25 is connected to three pipelines, and the effect of two electric butterfly valves 15 can be achieved by controlling one three-way electric control valve 25 to select the water outlet pipeline.

[0033]The working principle of the present invention is: when the anti-low temperature cooling water system is in a temporary shutdown state, when the temperature of the inlet and outlet water and the ambient temperature drop to a certain level, the anti-low temperature cooling water system enters the antifreeze mode, and the water pump 7 and the pipeline heating device 16 are turned on. All the cooling water at the water inlet end of the cooling tower 40 returns directly to the vicinity of the water ou...

Abstract

The invention discloses a cooling water system structure device used under a low-circumstance-temperature working condition. The cooling water system structure device comprises a cooling unit, a water inlet pipeline, a water outlet pipeline, a connecting pipeline, a cooling tower and cooling packing. A branch joint is arranged at the end, close to the connecting end of the cooling tower, of the water outlet pipeline. The water outlet pipeline is divided into a first water outlet pipeline and a second water outlet pipeline through the branch joint. The first water outlet pipeline is connected with the cooling packing. The second water outlet pipeline is directly connected into the cooling tower. The first water outlet pipeline and the second water outlet pipeline can be selected for water discharging according to different circumstance temperatures. Through the cooling water system structure device, the temperature of cooling water can be increased more rapidly, the electric heating time can be reduced, energy can be better saved, and emission is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration and air-conditioning equipment, in particular to a cooling water system structural device used under low ambient temperature conditions. Background technique [0002] Different demand sides, due to the special needs of production and technology, the year-round refrigeration water-cooled units and evaporative cooling units are more and more widely used. The cooling water of the unit comes out of the cooling tower water tank and passes through water pumps and other accessories to the unit condenser for replacement. The heat is then returned to the cooling tower, sprinkled from the upper part of the cooling tower, passes through the filler heat exchange to reduce the temperature, and then returns to the bottom water tank. When the product is used in winter, after the antifreeze mode is turned on, and the unit is in the antifreeze and auxiliary heating mode, when the cooling water enters the coo...
