Description

A Modular Data Center Chilled Water Air Conditioning System

technical field

The utility model relates to the field of air conditioning systems, in particular to a modular data center chilled water air conditioning system.

Background technique

With the advancement of informatization in various industries, the amount of data to be processed is increasing, and the requirements for data processing speed and processing capacity are also getting higher and higher, and data centers have emerged as the times require. A large number of servers are centrally placed in the data center to process related data. The servers are usually placed in the cabinets of the data center. Due to the large heat dissipation of the servers, they are placed in the data center in a centralized manner. If the servers in the cabinets are not timely and effectively Heat dissipation will cause the temperature in the computer room to be too high and cause damage to the server.

In the prior art, a chilled water air-conditioning system is usually used to solve the heat dissipation problem of the data center. A chilled water air-conditioning system in the prior art usually includes: an air-conditioning device arranged in a data center, a cold source, and a pipeline connecting the air-conditioning device and the cold source.

FIG. 1 is a schematic diagram of an internal top view of a data center in the prior art. As shown in FIG. 1 , the data center has a raised floor, on which air conditioners 101 and cabinets 102 in the data center are located. The air conditioner 101 is installed at both ends of the data center, and the air conditioner 101 usually adopts a special air conditioner for a refrigerated underwater blower room (hereinafter referred to as the downflow air conditioner for short). The cabinets 102 are arranged in rows in the data center. The same row of cabinets 102 is placed in the same direction, and two adjacent rows of cabinets are placed in opposite directions, forming a placement method in which the cabinet front 103 of two adjacent rows of cabinets faces the cabinet front 103, or the cabinet back 104 faces the cabinet back 104 . The aisle facing the front of a row of cabinets is a cold aisle. As shown in FIG. As shown in FIG. 1 , the back of the cabinet 104 and the aisle between the two rows of cabinets placed opposite to the back of the cabinet 104 , and the aisles facing the back of the two rows of cabinets at both ends of the data center are all hot aisles. The air conditioner 101 blows cold air into the plenum 106 located under the raised raised floor through the lower air supply port 105, and blows the cold air out through the floor air supply port 107 on the ground between the cabinets 102. Since there are cabinets on both sides of the cold aisle The front 103 is the front of the server placed in the cabinet. The server sucks in the cold air through its own fan, and discharges the hot air from the back of the server (that is, the back of the cabinet 104). The hot air is discharged to the hot aisle. The hot air in the space is sucked back by the air conditioner 101, and converted into cold air after being processed by the air conditioner 101, and continues to cool the data center.

The cooling source is connected to the air-conditioning equipment through pipelines. In the prior art, a water-cooled chiller is usually used to provide refrigeration for the air-conditioning equipment. The cold source of water-cooled chillers usually includes chillers located indoors and cooling towers located outdoors. The air conditioner is connected to the chiller through pipelines.

The air-conditioning equipment used in the chilled water air-conditioning system in the prior art is a large-scale downflow air-conditioning equipment, which is arranged at both ends of the data center to provide cooling for all equipment in the data center. Therefore, it needs to be considered according to the future capacity of the data center during deployment. The selected downflow air conditioning equipment, for example, the number of cabinets, the size of the server power, etc. However, in the initial stage of actual operation, only some cabinets may be put into use in the data center, and the downflow air-conditioning equipment arranged in the data center operates at the cooling power of all cabinets, so the energy utilization rate is low, and once the construction is completed and put into use, it is difficult to expand later. That is to say, the chilled water air-conditioning system in the prior art cannot be flexibly configured with the change of the number of cabinets in the data center; secondly, the cabinets with higher power The static pressure box under the raised access floor supplies the cabinet with cold air, and the air volume of the cold air supply will be limited by the cross-sectional area of the static pressure box (because the cross-sectional area of the static pressure box cannot be increased by raising the raised raised floor without limit), so , for cabinets with high power consumption, due to the limitation of the cross-sectional area of the plenum box, it cannot meet the cooling demand; moreover, in the prior art, the down-flow air-conditioning equipment is located at both ends of the data center, so if you want to provide The cabinets provide the same cooling capacity as the cabinets located at both ends of the data center, requiring greater power consumption of the downflow air conditioning equipment; finally, the data center in the prior art needs to provide a raised raised floor (as shown by 106 in Figure 1), Occupies the height of the building.

Utility model content
