[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0032] The utility model provides Figure 1 and Figure 4 A cold station flow control device shown in the figure includes a water-cooling unit 1, a first water storage tank 2 is provided on the right side of the water-cooling unit 1, and the water outlet end of the first water storage tank 2 is connected to a regulating mechanism, which includes a water pump 21, a first diversion pipe 23, a second water storage tank 3, a second electric valve 31, a second diversion pipe 32, a cooling water pipe 33, a third electric valve 34, a second water collecting pipe 35 and a temperature sensor 36. The second electric valve 31 is fixedly installed at the upper end of the second water storage tank 3, and the water outlet end of the second water storage tank 3 is fixedly connected to the second diversion pipe 32. There are multiple groups of third electric valves 34, and the multiple groups of third electric valves 34 are all fixedly installed on the right side of the second diversion pipe 32. The left end of the cooling water pipe 33 is fixedly connected to the third electric valve 34, and the right end of the cooling water pipe 33 is fixedly connected to the second water collecting pipe 35. The temperature sensor 36 is fixed on the upper side of the second water collecting pipe 35, and the lower end of the temperature sensor 36 is fixedly connected to the cooling water pipe 33.
[0033] Among them, the temperature sensor 36, the second electric valve 31, and the third electric valve 34 are all equipped with wireless transmission modules, which can be remotely controlled by the central controller. During use, the temperature sensor 36 monitors the water flow discharged from the cooling water pipe 33 in real time and transmits the monitoring information to the interior of the central controller. The central controller accurately adjusts the water flow in the area according to the monitored temperature. When the cooling water pipe 33 passes through the area where it is located, the discharged water temperature is very high, which means that the area requires a large flow of cold water for heat exchange and cooling. At this time, the second electric valve 31 and the third electric valve 34 are both fully open.
[0034] In addition, when some users on the floor do not use cold water for cooling, the central controller adjusts the opening and closing degree of the second electric valve 31 according to the number of users using it, so that the cold water flowing out just meets the cold water amount required by the users. When the temperature of the cold water discharged from the cooling water pipe 33 in the area where a certain user is located is low, the central controller reduces the opening and closing degree of the third electric valve 34 in the area, reduces the cold water supply in the area, and uses a smaller cold water position to reduce the temperature in the area, thereby realizing precise control of different floors and different users in the building, ensuring precise regulation of cold water, and effectively achieving the effect of energy conservation and emission reduction.
[0035] See Figures 1 to 3 The water cooling unit 1 is provided with multiple groups, the right sides of the multiple groups of water cooling units 1 are fixedly connected with the water outlet pipe 12, the left sides of the multiple groups of water cooling units 1 are fixedly connected with the water inlet pipe 11, the water outlet end of the second water collecting pipe 35 is fixedly connected with the return pipe 16, the end of the return pipe 16 away from the second water collecting pipe 35 is fixedly connected to the water inlet pipe 11 in the water cooling unit 1, the upper end of the first water storage tank 2 is fixedly connected with the transmission pipe 15, the end of the transmission pipe 15 away from the first water storage tank 2 is fixedly connected with the first water collecting pipe 14, the surface of the first collecting pipe 14 is fixed Multiple groups of first electric valves 13 are installed, and the right ends of the water outlet pipes 12 are fixedly connected to the multiple groups of first electric valves 13 respectively. The water pump 21 is fixedly installed on the right side of the first water tank 2, and the water outlet end of the first water tank 2 is fixedly connected to the water inlet end of the water pump 21. The water outlet end of the water pump 21 is fixedly connected to the first pipe 22, and the right end of the first pipe 22 is fixedly connected to the first diversion pipe 23. The right side of the first diversion pipe 23 is fixedly connected to multiple groups of second pipes 24, and the right end of the second pipe 24 is fixedly connected to the second electric valve 31 on the upper side of the second water tank 3.
[0036] Specifically, the water-cooling unit 1 cools down the water flow inside it, and the cooled water flow is collected into the first water collecting pipe 14 through the outlet pipe 12, and then collected into the first water storage tank 2 through the transmission pipe 15. Next, the water pump 21 draws out the cold water inside the first water storage tank 2, and transports it to the inside of the first diversion pipe 23 through the first pipe 22. Then, the cold water is diverted to different floors through the first diversion pipe 23 and multiple groups of second pipes 24. At this time, the cold water is discharged to the inside of the second water storage tank 3 through the second electric valve 31. Next, the cold water inside the second water storage tank 3 is distributed to the cooling water pipes 33 in different user rooms through the second diversion pipe 32. The cooling water pipes 33 perform heat exchange and cooling on the room. Then, the cold water after heat exchange and cooling on the same floor is re-collected into the inside of the second water collecting pipe 35, and flows back to the inside of the water-cooling unit 1 through the return pipe 16 for re-cooling.
[0037] The working principle of this utility model is as follows: the temperature sensor 36 measures the temperature of the cold water discharged by each user and transmits it to the interior of the central controller, and calculates the cold water flow required by the user. Then the central controller adjusts the second electric valve 31 and the third electric valve 34 to control the water for the designated user and control the cold water usage, thereby achieving precise regulation and effectively improving the energy saving effect.
