Description

Technical Field

[0001] The utility model relates to the field of design of chilled water supply systems for data centers, specifically a skid-type cold water system for data centers, which stably and reliably provides the chilled water required for the operation of the data center, while also saving floor space, improving system energy efficiency, and significantly shortening the construction period. Background Art

[0002] With the development of technologies such as big data, cloud computing, and artificial intelligence, the scale and number of data centers are constantly increasing. Data centers are highly intensive computing environments that generate a large amount of heat during operation. Therefore, efficient cooling systems are crucial infrastructure to ensure their stable operation.

[0003] This utility model is a skid-type chilled water system for data centers. Servers in data centers generate significant heat during operation, necessitating a highly efficient cooling system to maintain the equipment within a suitable temperature range. Furthermore, data centers consume significant amounts of energy, making the energy efficiency of chilled water systems crucial. Data center computer room space is limited, and the design must support expansion to facilitate on-demand addition of cooling capacity to meet future needs. Conventional data center chilled water systems not only require large floor space, require long construction cycles, require redundant piping, but also suffer from low system energy efficiency. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the Figure 1 This utility model is described in detail, and the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the embodiments described are only some of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this utility model.

[0019] The present invention provides a skid-type chilled water system for a data center. Figure 1As shown, it can be implemented as follows: the system includes a cooling hydraulic module 1, a cold source module 2, a chilled hydraulic module pipe 3, a sand filter 4, a cooling water dosing device 5, a cooling water pump 6, a chiller 7, a plate heat exchanger 8, a chilled water pump 9, a chilled water dosing device 10, a constant pressure device 11, a water supply tank 12, a cooling water supply pipe 13, a chilled water return pipe A14, a chilled water supply pipe 15, a chilled water return pipe B16, an electric regulating valve 17, a temperature sensor 18, a pressure sensor 19, and a flow sensor. 20, electric switch valve 21; the sand filter 4, cooling water dosing device 5, and cooling water pump 6 are connected through pipes and integrated into the cooling hydraulic module 1; the chiller 7, plate heat exchanger 8, electric regulating valve 17, temperature sensor 18, pressure sensor 19, flow sensor 20, and electric switch valve 21 are connected through pipes and integrated into the cold source module 2; the chilled water pump 9, chilled water dosing device 10, constant pressure device 11, and water supply tank 12 are connected through pipes and integrated into the chilled hydraulic module pipe 3. The cooling hydraulic module 1, cold source module 2, and chilled hydraulic module pipe 3 can be assembled and integrated in the factory and then shipped to the site. On site, the modules only need to be connected through the reserved pipe interfaces, which greatly shortens the installation and commissioning time, saves floor space, and effectively improves the system energy efficiency.

[0020] The refrigeration unit operates in three modes: normal cooling, full free cooling, and partial free cooling. When the outdoor wet-bulb temperature is below the set value for 20 minutes (adjustable), the chiller operates in cooling mode. The chiller regulates its load by controlling the cooling tower fan frequency (priority) and adjusting the opening of the electric control valve to ensure the outlet water temperature remains at the set value. If the outdoor wet-bulb temperature is below or equal to the set value for 20 minutes (adjustable), an audible and visual alarm will sound, shutting down the chiller and entering full free cooling mode. If the outdoor wet-bulb temperature is between the set value and the set value for 20 minutes (adjustable), an audible and visual alarm will sound, shutting down some chillers and the system will enter partial free cooling mode. Automatic control of these three cooling modes fully utilizes cold air for cooling, significantly improving system energy efficiency.

[0021] The utility model includes a cooling hydraulic module (including a cooling water pump, a cooling water dosing device, a sand rate controller, etc.), a chilled water hydraulic module (including a chilled water pump, a chilled water dosing device, a constant pressure device, a water replenishment device, etc.), a cold source module (including a chiller, a plate heat exchanger, etc.), cooling water piping, chilled water piping, an electric regulating valve, an electric on-off valve, a pressure sensor, a temperature sensor, a flow sensor, etc. The cooling water pump, cooling water dosing device, sand rate controller, and supporting pipes and valves are integrated into the cooling hydraulic module; the chilled water pump, chilled water dosing device, constant pressure device, water replenishment device, and supporting pipes and valves are integrated into the chilled hydraulic module; and the chiller, plate heat exchanger, and supporting pipes and valves are integrated into the cold source module. This achieves flexible expansion, avoids over-cooling and energy waste, saves machine room space, and significantly shortens system installation and commissioning time.
